The technical field to which the invention relates

The present invention relates to mechanical engineering and can be used in mobile objects for efficient cooling of the heating in the process of its constituent units by circulating in the fluid output after heating in the unit and is cooled in the heat exchanger, for example: mobile radar stations for cooling phased array antenna in the process of radiation, which generates a large amount of thermal energy.

The level of technology

A device containing a mounted on a wheeled vehicle frame, a container in which is placed a cooled object, connected by a piping system composed of suction pump with hub and pressure with the accumulator highways with two series-connected heat exchangers mounted on one another and additionally forced cooled by fans mounted on the top of the housing, on the underside of which is secured the upper heat exchanger and the housing is fixed inside the frame, which has all the elements combined into a separate unit with front panel mounted on the frame, the bottom of the heat exchangers is supplied from the lower �their side of the suction duct, and over the top fan forced - exhaust duct, the opposite ends of which are mounted on the frame on the inner side of the front panel of the unit, with the outside in which these places are installed at the openings of the ducts of the rotary cap, the axes of rotation of which is on one side fixed arms pivotally connected to each other by means of thrust, and on the other side of the axis of the bottom cap installed similar lever pivotally connected output shaft of the electrically operated, providing linear reciprocating movement of the rod, and levers on axes made of different lengths from the axis of its rotation to the swivel axis with a thrust or piston rod, wherein the system contains several similar cooling blocks mounted along the entire length of the container adjacent to each other in the opening of the container, at the top of each opening of the container is fixed spring-loaded stop interacting with its inclined surface with a similar conical surface of the stop mounted on the outer surface of the frame of each of the cooling units, also under the front panel of each of these blocks on the wall of the container frame alternately placed with stretch marks in the upper part on both sides, and in this frame is fitted with a roller carriage, p�remesiana on the frame by passing the screw-nut and attached to the frame via the front panel by means of two intermediate parts, and on the upper outer surface of the frame from both sides at the point of attachment under the front panel is made grooves for secure installation on the frame of the cooling unit bracket with roller and stationary ledge beneath him after a partial pull-out unit from the container into this frame.

The disadvantage of this device is its insufficiently high functional and operational capabilities, which consists in that when the location of the heat exchangers on each other decreases the efficiency of heat transfer of the upper heat exchanger due to blowing his bottom with warm air from the bottom of the heat exchanger. In addition because of the location of the heat exchangers inside the container there is no natural (convection) heat exchange with the environment and is not possible in this design to use a greater number of forced fans. In addition, since the heat exchange efficiency depends on the resistance in the air path and shape to the heat exchanger, the small cross-section of the suction duct and its angular shape reduces the efficiency of forced fans, i.e., the heat transfer deteriorates. Insufficient operational capabilities is a long-time maintenance and / or repair the cooling units for alternately�about the nomination of these units attachable to the frame with stretch marks, installation and rearrangement which serviced units and their extension on it and return retraction into the container takes considerable time.

The proposed multi-channel liquid cooling system of the mobile object contains mounted on a wheeled frame 1 of the vehicle turning the container 2, in which is placed a cooled object 3 is connected through a piping system consisting of a suction pipe 4 of the pump unit 5 and the discharge line 6 from the accumulator 7 in a closed circuit through the series-connected one behind the other heat exchangers 8, further cooled by electric fan (fan forced) 9, in the aggregate are combined in a separate cooling unit (within the system of their twelve), functioning independently and in parallel to other similar units and consisting of the intermediate body 10 and the front panel 11. Such blocks are located next to each other across the wall of the container 2 and for compactness combined two units into one module with a total for both blocks face plate and intermediate housing (see Fig. 1 and 2), wherein each cooling unit to the cooling object 3 are fed by two pipelines passing under the roof of the container 2 (not shown) made of flexible tubes in places of transition from the container 2 to the object 3 and the container 2 to the hydraulic system in each cooling unit. The intermediate casing 10 is installed in the opening (about�Seca) of the container can be rotated in a vertical plane on the additional axes 12, mounted on each of the side walls of an aperture coaxially to each other.

To the intermediate housing 10 from the opening of the container is connected to the heat exchangers 8, and the opposite - the fans 9 with the exhaust duct 13, the opposite ends of which are located in the respective holes of the front panel 11, on the outer side of which the axes 14 of the intermediate casing rotatably mounted on the cover 15, and on the same axes fixed arms 16 pivotally connected to each other by a rod 17 formed thereby lever-parallelogram mechanism to ensure simultaneous rotation of all caps.

With one of the links of the mechanism is pivotally connected to the coupler 18, the other end of which is pivotally connected on the axis 19 with the additional lever 20, through which additional leverage is pivotally mounted through the axis 21 on the intermediate casing 10, and the opposite end is articulated on the axis 22, and on the same axis is pivotally mounted to an additional rod 23, the opposite end of which is pivotally mounted on the container rear wall of the opening (not shown). The axis 22 in turn is loosely fitted in the oval grooves 24 of a bracket 25 of the tubular form of rectangular cross section, performed on both vertical walls. Lower part of this bracket is fixed to the output rod 26 specificati�charisma 27, and at its inner upper horizontal surface has a different height platforms 28 and 29, the vertical transition between which is situated in the same plane with the axis of the groove 24, and the lower surface of the pad engages the radial protrusion 30 more traction 23 when you move the rod down from its extreme extended position, and placed under the upper platform 29 when fully retracted stem electromechanism, the body of which its lower part is pivotally mounted on the side wall of the opening of the container (in the drawings conventionally not shown), and stroke 26 for electrically operated to its extended position is limited additional resistant ledge 31 on the wall of the aperture. At the bottom of the bracket 25 is pivotally mounted to the strap 32, which is located along with the electrical mechanism 27 and its opposite end in the lower part of the opening pivotally mounted on the emphasis of a container made in the form of a latch 33, and located at the maximum radius of rotation of the protrusion 34 in turn communicates with the abutments 35 and 36 on the intermediate casing 10 of the cooling unit in each of its extreme positions. The axis 22 with fixed lever 20 and rod 23 is in the operating position of the system when the extended rod 26 above the axes of rotation of the opposite ends of the same lever and thrust.

The implementation of the invention

Proposed �mnogokanalnoj liquid cooling system of a mobile object in each of its channels works as follows: initially included electrical systems 27 (each side of the module), when nominating output rod 26 (see Fig. 5 and 7) initially moves up the bracket 25 relative to the fixed axis 22 until the stop of the lower end of the groove 24 in this axis: for this movement simultaneously lower the platform 28 in this bracket rose above the radial protrusion 30 29 thrust, and the protrusion 34 is disengaged from the stop 35 on the intermediate housing 10 by rotation of the latch 33 of the strap 32, thereby cooling the unit as a whole refexive from transport position (shown in Fig. 4). Upon further advancement of the rod 26 of the bracket 25 of the lower part of his groove 24 moves up the axis 22, thereby turning the lever 20 and rod 23 to the stop bracket 25 in additional thrust shoulder 31 on each side wall of the opening of the container. Simultaneously at turn thrust her 23 radial protrusion 30 overlaps the lower pad 28, the intermediate body 10 turns on the secondary axis 12 from exposure to the axle 21 of the pivoting lever 20. Simultaneously, the coupler 18, turning on committing arcuate movement of the axis 19, acts on the lever-parallelogram mechanism of opening of the lids 15: turning one of the levers 16 on the axle 14, rotates, and simultaneously opens all of the cover 15. The opening angle of the lids 15 depends on the ratio of the shoulders in the levers 16 and 20. Simultaneously climbing strap 32 steering�et the latch 33 to call her ledge 34 in the counter roaming cap (groove) 36. Going down the ledge 34 in the groove 36 of the intermediate body 10 is ensured by the fact that at the time of his entry into this groove the axis of rotation of the lever 20 and 23 and the thrust axis 23 are arranged on one line, i.e., at the approach to this position, and further movement resistant up to an additional protrusion 31 moves the intermediate housing 10 and, accordingly, the groove 36 in the horizontal plane is many times less than the movement of the protrusion 34 in the vertical direction. When passing through the axis 22 this "dead spots" and further upward movement to the contact I of the bracket 25 with additional thrust ledge 31 is pivoted on the secondary axis 12 of the intermediate casing 10 commits mini turn down, dojima the protrusion 34 to the bottom of its groove 36.

Thus, in the working position of the system put forward by the rotation method of opening the container module of the two cooling blocks its mass through the axis 21 of the lever 20 and the axis 22 presses via a webcam on it traction 23 radial protrusion of the bracket 30 to 25 additional resistant ledge 31 on the container, i.e. the stem 26 27 for electrically operated unloaded from axial forces, and additional fixation protrusion 34 in the groove 36 forms a fixation nominated for the cooling module (see Fig. 3).

Next, turn on the pump unit 5 and pumps the coolant from the cooled object 3 via pipelines�the delivery of 4 and 6 and the coil 8 and the accumulator 7 round on this closed circuit. Forced fans (electric fans) 9 is further cooled heat exchangers 8, sucking air from the side of the container 2, and releasing hot air through the exhaust duct 13 from the opposite side.

The translation process of the cooling module from working to transport position, followed in fixing it is done in reverse order (see Fig. 3): is the electrical mechanism 27 in the mode of being drawn into the rod 26 is thus moved together with the bracket 25 with its surface 28 via the radial projection 30 traction 23 moves down the axis 22, thereby turning mounted on the lever 20 and the thrust 23. Before the approach axis 22 to the "dead point" (the point on the same line with the axis 21 and the axis of rotation 23 on the thrust wall of the container) of the intermediate casing 10 is moved in small increments to the left on the secondary axis 12 (see Fig. 3), thereby contributing to the output of the ledge 34 of the latch 33 from the groove 36 of the intermediate body 10, since the linear movement of the protrusion 34 is significantly greater than the displacement of the walls of the groove 36.

Only after the axis 22 of the "dead point" begins the process of rotation of the cooling unit on the secondary axis 12 inside the opening of the container: the bracket 25 with its surface 28 presses on the radial protrusion 30 thrust 23, thereby the thrust and the lever 20 is moved together with the axle 22 down (OST�is fixed with respect to the groove 24, while in its lower part), turning on her, which leads to the end point of their rotation: pull rod 23 to its radial projection 30 will be released from contact with the pad 28 of the bracket 25. as the lever 20 through the axis 21 will turn the intermediate casing 10 in the lowermost position, wherein the front panel 11 in contact with the outer surface of the container 2, completely closing the opening therein. Additionally, the axis 19 of the lever, making a turning movement along the radius relative to the axis 21, will entail a coupler 18, which with its opposite end will turn the lever 16 on the axle 14, and by the rod 17 and the other levers 16 of this lever-parallelogram mechanism and close all covers 15 on the front panel 11. In addition descends strap 32, also turning down the latch 33. This situation is depicted in Fig. 4: the modulus of the two cooling blocks transferred to the transport position into the opening of the container 2, but not fixed. Upon further retraction of the inside of the electromechanism 27 of the rod 26 with the axis 22 of the lever 20 and rod 23 remain stationary and floating down through the groove 24 (each wall bracket) bracket 25 through the bar 32 makes further down the latch 33. which ledge 34 captures the intermediate casing 10 in the transport position resting on the stops 35. At the same time the radial protrusion 30 is located underneath the surface�TEW 29 of the bracket 25 (see Fig. 5).

Each of the cooling modules included in your opening of the container and are fixed in position, the vehicle is ready for movement.

Shown in Fig. 8...14 versions of the cooling unit are the same as the above, have the same mechanism for moving this unit from the transport position and back by fixing into the end position of the move (so these mechanisms on their drawings not shown) and differ mainly by the configuration of the intermediate body 10 and located in relation to forced him fans and heat exchangers, which are presented in two sizes, withstanding the ratio of the two embodiments, the heat exchanger in Fig. 2...5 is equivalent to the heat transfer to the three smaller sizes of the heat exchangers in the variants of Fig. 8...14.

Multivariance of the presented structures due to the required power dissipation for an actual working design, and also the conditions in which it is applied.

So, for example, variants in Fig. 8, 10, 11, 13 with a horizontal arrangement of the 9 most fans for optimal performance during precipitation, while in Fig. 9 and 14 with a vertical electric fan is the most optimal according to the criterion of efficiency of heat transfer, because they practical�ski is possible the leak is from the bottom of the heat exchangers coming from fans of hot air even in a strong crosswind, which will only serve to exacerbate the cravings of fans, also this design can work and when precipitation provided that extends from the exhaust duct airflow overcomes the pressure of these precipitation and when you disconnect the fans during the folding of the product in General in the transport position inside the water will drain out through the drainage holes.

The advantages of multi-channel liquid cooling system of the mobile object are:

- increased efficiency of heat exchangers by applying for them blowing more fans, in some embodiments, is also due to the greater size of the heat sink surface in a greater number of heat exchangers;

- increased efficiency of heat exchangers by reducing the resistance to the suction of air in the heat exchangers (no suction ducts) and series-connected heat exchangers are located near each other and due to the natural (convection) cooling of heat exchangers in the open air, i.e. increases the functionality of the device.

In addition, expanded operational capabilities of the system: separate automatic extension of the cooling modules from the openings of the container provides quick and easy access� the possibility of carrying out the maintenance and / or repair in less time and eliminates the use of additional devices for his nomination. Also available for maintenance and the internal cavity of the opening of the container. While all these activities may take place immediately after the completion of the product.

It is also evident that despite the use in the cooling unit of a larger number of fans (as well as heat exchangers that size) occupied by unit volume in the rotary container is not increased due to the exceptions to the overall design of the suction duct and reduce the size of the exhaust duct.

SUBSTANCE: invention relates to systems for heat removal from computer equipment mounted inside server or mounting cabinets, and namely to a condensation cabinet. The condensation cabinet consisting of a protective casing; two and more injectors serving for spraying of a mixture into an inner cavity of the cabinet; highly heat-conducting plates with installed heat releasing equipment; thermoelectric batteries (TEB); heat bridges; a pin fin heat sink; a fan unit; a control unit (CU); a condensate flowing-down chute; a pump serving for the supply of condensate to injectors, and a temperature sensor involves an evaporation and condensation cooling principle. Liquid is injected through the injectors located on the cabinet ceiling into the inner cavity of the cabinet; after it is deposited on heat releasing elements, it is evaporated, and therefore, the heat releasing elements are cooled down. Liquid vapours are condensed on the ceiling (upper part of the cabinet) that is technically made with an inclination to a rear wall of the cabinet for directed condensate flowing-down. In order to strengthen condensation properties of the evaporated liquid, TEB having a close contact of cold junctions to the upper cover plate of the cabinet are used, and the mounted pin fin heat sink that is also in close contact to TEB junctions, but already on the hot side, performs the heat pick-up. The heat bridges are located between TEB (they alternate in a staggered order with TEB) and serve for cooling of the upper surface of the cover plate by means of the pin fin heat sink and the fan units without any activation of TEB to save electric energy. The fan unit consisting of four fans is controlled by the control unit (CU) that gives a possibility of their pair activation for the purpose of electric energy saving by blowing over a radiator. TEB is fed through CU. A condensed mixture on the upper cover plate flows down through the rear wall and penetrates onto a special chute located throughout the length of the rear wall. From there, it is supplied via the liquid channel to CU, in which a pump is installed. The mixture is supplied back to the injectors through the liquid channels under the action of the pump.

The temperature sensor supplies a signal to CU that includes a pump for liquid supply to injectors located on the cabinet ceiling. The mixture is injected to the internal cavity of the cabinet and deposited on heat-emitting elements; its evaporation process takes place, therefore, cooling of heat-emitting elements is achieved. When vapours of the mixture go upwards, they are condensed on the ceiling (upper part of the cabinet) that is technically inclined to the rear part of the cabinet for directed condensate flowdown onto a special chute located throughout the length of the rear wall. Then it enters CU, in which the pump is installed. The mixture is supplied again to the injections through liquid channels under action of the pump. In order to amplify condensation properties of the evaporated liquid, the thermoelectric units are used, the cold junctions of which are in close contact with the upper cover of the cabinet, and the installed pin fin heat sink that is in the same close contact with the junctions of the thermoelectric units, but is on the hot side, performs heat removal. The fan unit consisting of four fans is controlled by the control unit (CU) that provides the possibility of their paired actuation for the purpose of electric energy saving.
