Known water containing exhaust tower with pool in the lower part with inlet and outlet pipes, partitions, finned heat pipes, spray devices before heat pipes, closed housings with louvered openings [1].

A disadvantage of the known device is the need to use water cooling refrigerant-air and the need for a considerable amount of energy for which utilizacii low-grade heat of the liquid, comprising a housing with top and bottom plates, fittings inlet and outlet for cooled liquid, which is placed inside a horizontal partition dividing the internal volume of the shell height at level rise and cooling and attached to the inner surface of the shell with flanged slots (vertical walls attached to the slits), forming a lifting tunnels, side (vertical partitions) directed downwards, forming between the edge of the tunnel and below the horizontal partition gap, sufficient for the passage of fluid; an internal cavity of winding tunnels filled porous nozzle, part of which rises above the surface of the upper horizontal walls, and the other reaches the upper surface below the horizontal septum and the surface of horizontal and vertical partitions covered with or made of hydrophilic and hydrophobic materials [2].

The disadvantages of the known devices include the need to create expensive and bulky reinforcing structures for sustainable location in space, due to the fact that the optimal value of the parameters of the cooling is achieved when eenie height of the device, due to the lack of messages misunnelig cavities with each other and the atmosphere and leading to the cessation of movement of the fluid, which reduces the reliability of the device.

The technical task to be solved by the invention is to simplify the design and increase the reliability of the device.

The task is implemented in a capillary cooling unit including a housing with top and bottom plates, fittings inlet and outlet of fluid, which is placed inside the horizontal septum and connected to vertical plates with a gap between its lower edge and the plane of the lower horizontal wall separating the cavity of the body on the steps of lifting and cooling systems made of or coated with a hydrophilic and a hydrophobic material and filled with a porous nozzle, and the upper horizontal partition made without cracks and below the horizontal partitions are made with slits, vertical walls are connected alternately through one of its top or bottom edge with the surface of the adjacent upper or lower horizontal partitions with the creation of cracks, alternately located at the bottom or top of Gori is diversified partitions arranged alternately along the fluid through one n hollow levels of education of the free surface, n-1 cooling stages and one notch of uplift and cooling, and the cooling stage filled porous nozzle so that it partially protrudes from the upper slits, occupying the upper part of the hollow cavity of the levels of education of the free surface, which are interconnected by vertical equalization tubes with holes in the top of each stage, passed through all of the horizontal partition, and a top cover provided with an air fitting.

The technical result of the invention is to obtain the optimal parameters of cooling water by repeated manual lifting fluid in the capillaries of the porous nozzle cooling stages, Oceania her on the hydrophilic surface of the vertical partitions to the bottom of the hollow rungs and education there is a free surface on each horizontal partition, multiple stepwise rise in capillary porous nozzle cooling stages and rise to the top horizontal partitions and create equal pressure in all the volume of the device.

The drawing shows the proposed capillary water.

Capillary cooling unit includes a housing 1 with the upper and lower covers 2, sleep is th posted by horizontal partitions 6, vertical partition 7 divides the cavity of the housing 1 between each two nearby horizontal partitions 6 are located alternately in the direction of the hollow liquid level of the free surface 8, the cooling stage 9, stage lifting and cooling 10 filled with a porous nozzle 11 so that the portion of the porous nozzle 11 is located in the cavity of the hollow level of the free surface 8, a few speaking from the gap the cooling stage 9 and rising above the plane of the horizontal partition wall 6, the bottom surface of the horizontal partitions 6 and the surface of the vertical partitions 7, the front flow of liquid covered with a hydrophobic material 12, the other surface of the partition walls 6, 7 is covered with a hydrophilic material 13, the pressure compensation tube 14 is passed through all of the horizontal partition 6 with holes 15 in the upper part of the hollow rungs of the free surface 8.

The basis for the offer of capillary water on the way speed of capillary rise of a liquid, accompanied by her cooling by reducing the heat content of the surface layer and the increase of pressure due to its climb to a certain height, and the function of the cap is to be placed and lifting 10 [2, 3].

Capillary water works as follows. The circulating water after it is heated in the heat exchange apparatus with temperature tgthrough the fitting 3 is served in the lower, first in the direction of the hollow liquid level of education of the free surface 8 in a quantity sufficient to lower the gap of the first stage 9 was flooded; and then begins the ascent of the water due to capillary forces in the porous nozzle 11 to a height h to a hydrophobic surface viseslava horizontal partitions 6, which repels water particles, the saturation of all the capillaries of the porous nozzle 11, a portion of which protrudes from the upper slit the cooling stage 9, in contact with the hydrophilic surface of the vertical walls 7, which is due to the combined effects of gravity forces hydrophilic surface vertical partitions 7 and gravity drains the water, which is collected on the hydrophilic surface of the horizontal partition 6 step 8 with the formation of a free surface, reducing its heat content, and accordingly, the temperature attC, reaches the lower slots following the cooling stage 9, after which the process of movement and olabode surface 8; then the water reaches the bottom of the slit-stage cooling and lifting 10 rises due to capillary forces in the porous nozzle 11 to a height h, spreads over the hydrophilic surface of the hollow stage 9 viseslava horizontal partitions 6, while reducing its temperature totC, reaches the bottom of the first slit in the direction of fluid the cooling stage 9, where the cooling process and recovery is the same as the above, to the upper horizontal partition 6, where the water is cooled to a temperature t0comes to the consumer. The parameters of water will be equal to

t0=Nnt; (1)

H=Nh; (2)

where N is the number of horizontal partitions 6, PCs;

n is the total number of cooling stages 9 and lifting 10 on one horizontal partition 6, PCs

At the same time, due to the fact that all hollow level of education of the free surface 8 are communicated with each other through the balance tube 14 with holes 15, and through the air nozzle 5 and with the atmosphere, in the whole volume of the device are set to the same pressure equal to the atmosphere to the outlet fitting 4 and then fed to the consumer.

Thus, the proposed capillary water can reduce the height of the device in comparison with the known n times, providing a stable position it in the space without reinforcing structures and maintains uniform pressure throughout the volume of the apparatus, which simplifies the design and increases the reliability of the device.
