The proposed liquid cooling system of a mobile object contains mounted on the wheeled frame 1 of the vehicle rotating container 2, in which is placed the cooled object 3, which is connected through a piping system consisting of a suction pipe 4 with a pumping node 5 and the pressure line 6 with the hydraulic accumulator 7 in a closed loop through a heat exchanger 8, further cooled by two fans, 9, together United in a separate cooling unit consisting of a frame 10 and the front panel 11. These blocks are located next to each other across the wall of the container 2 (see figure 1), with each cooling unit for cooling the object 3 summarizes p. the two pipelines, passing under the roof of the container 2 (conditionally not shown)made of flexible tubes in places of transition from container 2 to the object 3 and the container 2 to the hydraulic system in the frame 10 (see figure 2).

The heat exchangers 8 of each of the cooling units equipped with its lower side suction duct 12, and from the top over the forced suction ventilation of the two electric fan 9 to the exhaust duct 13, the opposite ends of which are secured to the frame 10 from the inner side of the front panel 11 of the cooling unit, with the outer side of which the frame is installed on the axis 14 of the same rotary cover 15. Below the front panel 11 of each of the cooling units on the wall of the container 2 in turn is attached frame 16 with stretch marks 17 in its upper part on both sides, and in this frame is fitted with roller carriage 18 with rollers 19, moved along the frame by passing the screw 20 - samoustraniajutsia nut 21. The carriage 18 is fastened to the frame 10 through the panel 11 by means of two intermediate parts 22 in the upper part and a lower part, these parts are inserted into the groove on the carriage 18 and can seal bolts (see figure 5). On the upper outer surface of the frame 16 from both sides in the direction of its attachment to the container 2 under the front panel 11 is made grooves 23 for the stop on the frame 10 of the brackets 24 with a similar roller 19 by a roller 25 in the upper part of the bracket and the fixed protrusion 26 in the lower part of the bracket, installed on the frame 10 is made after partial pull-out of the cooling unit from the bracket 2 on a frame 16.

On the axis 14 of rotation of each of the lids 15 on the one hand fixed to the levers 27 and 28 pivotally connected to each other by means of thrust 29, and on the other side of the axis 14 of the lower cover 15 is installed similar in shape to the lever 30 is connected to the output shaft 31 electromechanism 32, providing linear reciprocating movement of your rod and the levers 27, 28, 30 are made of different lengths, i.e. have a different size from the axis of its rotation to the axis of the swivel with a thrust or shaft. Case electromechanism 32 pivotally mounted on the frame 10.

On the outer upper surface of the frame 10 of each of the cooling units has a conical stop 33, interacting with its inclined surface with the same surface of the spring stop 34, fixed to the container 2.

The implementation of the invention

The proposed multi-channel liquid cooling system of a mobile object in each of its channels works as follows: initially starts electromechanism 32, when the extension of the output shaft 31 which rotates the hinge with it connected to the lever 30, opening the bottom cover 15, while the rotation axis 14 is transmitted to the lever 2 and further through the rod 29 of the lever 27, which rotates the upper axis 14, thus opening and the top cover 15, while the bottom of the lid 15 is opened at an angle less than 90°, to reduce the suction to the inside of precipitation, and the upper angle greater than 90° to avoid reflection from her down leaving the top of the duct 13 hot air. The possibility of opening the covers 15 different angles is provided by selection of the length of the levers 27, 28, 30. Further included the pump Assembly 5 and the electric fan 9: coolant on highways 4 and 6 passes through the heat exchanger 8 for its cooling efficiency is enhanced by further blowing an electric fan 9, which provide in the suction duct 12 directional air flow, which also increases the efficiency of the heat exchanger 8 and minimizes the influence of the heat from the similar heat exchangers in the adjacent cooling blocks. Hydraulic accumulator 7 when this stabilizes the operation of the hydraulic system: allows you to smooth out the pulsations of pressure of the coolant and compensates for its expansion arising in the process of pumping pumping node 5. Heated in the heat exchanger 8, the air is also directed air flow exits through the outlet duct 13, thereby creating an additional barrier to the external atmospheric influences, nab is emer, the rain from the suction duct 12. In addition, the proposed air supply system is isolated from contact with the interior of the container 2: all the air that is sucked through the duct 12 exits through the duct 13. Obviously, for maintenance or repair of any of the cooling units must be completely removed from the container 2. To implement this feature with maintaining efficiency of the product as a whole in the proposed device to the front panel 11 to be removed from the cooling unit on the vertical wall of the container 2 is attached frame 16 with stretch marks 17 from both sides, forming a kind of reception table for proposed cooling unit. The frame 10 of the cooling block size is less than the face panel 11, so the unit cannot be extended directly to the frame 16. To ensure the extension unit on the frame 16 is a roller carriage 18, which by passing the screws 20 and nuts 21 moves to the front panel 11 and through the two parts 22 fastened to the frame 10 (see figure 5), while the lower part of the parts 22 is placed in the slots on the carriage 18.

After unlocking the front panel 11 of the locking device, for example, depicted under the covers 15 figure 2 and 6 (this is the device shown in the Locked position), cooling BL is prepared to raise. The rotation of the screw 20 moves the carriage 18 on the rollers 19 on the frame 16 and, accordingly, raise the frame 10 of the same profile of the opening in the container 2, while if the front part of the frame 10 is moved on the rollers 19 on the frame 16, the rear part of the private guides in its lower part, for example, on rollers (see figure 2). The process of this extension shall be suspended for a set of brackets 24 on the frame 10 at the time of coincidence of the slots 23 with the mounting location of the bracket on a retractable frame 10 and then continues until full extension of the frame at a distance, providing access to the vacant opening in the container 2 for inspection and maintenance and in it: remove dust, grease rails, etc. and after the installation of the brackets 24, the frame 10 is moved along the frame 16 in addition to the rollers 19 on the rollers 25. Electricity and hydrowash with extended block is not interrupted due to the flexible tubing and electrical cables between the container 2 and the frame 10 of the cooling unit (see figure 2). From unauthorised tipping advanced unit on the frame 16 protect the parts 22 and the protrusions 26, coming under the frame 16.

After maintenance or repair cooling unit can be tested for efficiency in extended condition of the frame 16.

The retraction is installed on the frame 16 of the block in the container 2 productivity is implemented in reverse order: the rotation of the screw 20 to move the roller carriage 16 and is bonded with the frame 10 is moved to the location of the brackets 24 opposite the grooves 23, at the same time frame their 10 track rollers on its lower plane will be included in the guides in the opening of the container 2. Remove the brackets 24 and continue the process of sadhane frame 10 into the opening until it stops its focus 33 in the spring stops 34 (see figure 10), thereby locking the frame 10 in a vertical direction, and the locking mechanism locks it in a horizontal direction. Podpruzhinennom stop 34 provides a adjust to any misalignment of its conical rolling element without additional adjustment of the focus in General in each of the openings of the container 2, where the cooling blocks. Then removed the frame 16 with stretch marks 17: the product is ready for use.

The advantages claimed for a liquid cooling system include: improved efficiency of heat exchangers by providing a passage through them directed air streams are not dependent on the heating of the neighboring blocks that allows you to set close to each other similar cooling units without reducing the performance of each of them, i.e. increases the functionality of the device.

In addition, expanding the operational capabilities of the system: hanging outside for more of the receiving table, consisting of a frame 16 with stretch marks 17 and the carriage 18, allows the operations staff to produce comfortable you shall Viganj-retraction of the cooling unit from the container 2 for maintenance or repair, being directly on the surface location of the vehicle, i.e. without additional supports, etc. are Also receiving this table is both operating and production facilities and technological adaptation, because it allows you to install a new cooling unit when it is replaced in the operating organization and the primary installation at the factory, which reduces the number of used special equipment. Also provides full extension cooling unit out of the opening of the container 2 with providing service to the internal cavity of the opening and checking of the block after it has been repaired in the extended position.
