However, the conventional water cooling device is basically a fixed device, and is faced with the working condition requirement of rotating along any axis for a long time, because leakage occurs, air is sucked into a pipeline circulation system and other faults, the conventional water cooling device basically cannot work normally, particularly, after the air is sucked into the pipeline system, the cooling system occupies the space of the cooling liquid because the air occupies the space of the cooling liquid, so that a heating component cannot fully contact the cooling liquid, poor heat dissipation is easy to occur, and the temperature rise is rapidly increased, so that serious faults of burning loss of devices are caused. Because of the many problems associated with the use of water cooling systems in space rotary equipment, the heat dissipation of the space rotary equipment, despite the greatly improved power density, still has to rely on air-cooled cooling. The disadvantages of low heat dissipation power density, large volume and the like of an air cooling heat dissipation mode have severely restricted the development of equipment, and the equipment is very necessary to be solved.

The liquid in the cavity of the outer water tank is collected to the middle converging cavity 4, an annular converging cavity 2 is arranged around the heat exchanger water tank, a water inlet 3 is arranged on the annular converging cavity 2, and the water inlet 3 is arranged at the middle part of the annular converging cavity; the center of the heat exchanger water tank is provided with a middle converging cavity 4, and the water outlet and inlet of the heat exchanger water outlet 6 are arranged at the center of the middle converging cavity; the annular converging cavity 2 is communicated with the middle converging cavity 4 through a guide pipe, a core body 1 is arranged between the annular converging cavity and the middle converging cavity, a core body flow passage or a guide pipe is arranged in the core body 1, the annular converging cavity around the heat exchanger water tank is communicated with the middle converging cavity positioned at the center of the heat exchanger through the core body flow passage or the guide pipe, so that water of the heat exchanger is converged into the middle converging cavity and is discharged from a water outlet positioned at the center.
Fig. 1 shows a heat exchanger for water-cooling heat dissipation of a space rotation device, which can rotate on any axis without sucking air and has an expansion tank function; the heat exchanger comprises a core body 1, an annular converging cavity 2, a middle converging cavity 4, a water inlet 3 connected with an external circulation system, a water outlet 6 connected with a water pump and a conduit 5 communicated with the water outlet.
The core body 1 is separated by the middle converging cavity and is divided into a left core body and a right core body which are identical, and the two core bodies can be manufactured separately and independently or can be manufactured together by communicating the middle converging cavity.
As shown in fig. 2, the width of the water inlet is ensured to be smaller than the thickness of the cavity of the water tank at the outer side during the manufacture of the core body, and bubbles in the water tank are ensured not to enter the core body flow channel 7 at the horizontal position. Meanwhile, the water inlet part of the core runner 7 of the core 1 is lengthened, so that the water inlet of the core runner 7 extends into the outer water tank cavity 2 to protrude a certain length, and the air which does not reach the purpose of moving in the water tank rotating process cannot enter the core runner 7. The matching part of the core body 1 and the middle converging cavity keeps the same as the width of the middle converging cavity 4, which is beneficial to the discharge of gas.
The guide pipe 5 is welded on the middle converging cavity, so that the guide pipe 5 extends into the right center of the converging cavity, the inlet 8 of the guide pipe 5 is arranged at the center of the middle converging cavity 4, the length of the guide pipe is controlled, and the guide pipe is connected to the water outlet 6 (the position of the water inlet and the water outlet can be adjusted according to the actual structural requirement, the diagram is only illustrated) so that the liquid level 9 in the box is always above the inlet 8, and the sealing performance of the middle converging cavity is inspected after the completion.
As shown in fig. 3, the core body 1 and the middle confluence cavity 4 are welded and wrapped by an outer side water tank cavity except a ventilation surface, the inner wall of the water tank of the outer side cavity is kept smooth as much as possible, and the outer side water tank cavity and the heat exchanger core body and the middle confluence are integrated. The width 10 of the core flow channel 7 is smaller than the width 11 of the core 1; the width of the core 1 is smaller than the width 12 of the hollow of the outer water tank cavity.
And a water inlet 3 is formed in the cavity of the outer water tank, and the tightness of the whole heat exchanger is checked.

Because the heat exchanger and the water cooling device rotate at a relatively low speed in the process of rotating movement, bubbles have enough time to transfer in the switching process of various typical working conditions, so that the bubbles are always at the highest point of the heat exchanger and cannot enter other working devices such as a heat exchanger core flow channel, a water pump and the like. Meanwhile, residual bubbles exist in other positions of the closed circulating water system due to various reasons, and all the bubbles are finally collected into a cavity around the heat exchanger through the circulation of liquid.

Further, the water outlet of the heat exchanger is arranged in the middle of the heat exchanger, namely, the inlet of the water outlet of the heat exchanger is arranged in the center of the heat exchanger, and circulating cooling water entering the heat exchanger is collected to the center of the heat exchanger from all directions and then discharged from the water outlet positioned in the center of the heat exchanger.

Has the following characteristics:
1. the heat exchanger and the water tank are integrated into a whole, the periphery of the heat exchanger is designed into a communicated water tank cavity, the water inlet is arranged on the water tank cavity at the outer side, and when the heat exchanger rotates in space, gas can move rapidly in the water tank cavity and is always at the highest position in the water tank cavity. The thickness of the outer water tank cavity is larger than the size of the water inlet of the core body, so that air cannot enter the flow channel of the core body when the heat exchanger is placed horizontally. The core runner is deep into the outside water tank cavity by a certain distance, so that when the heat exchanger rotates, bubbles with slower moving speed can not enter the core runner, and the separation of water and gas is realized.
2. The middle converging cavity is arranged in the middle of the heat exchanger, the water outlet is positioned in the middle converging cavity at the right center of the whole heat exchanger, the water outlet is always below the liquid level, and bubbles cannot enter a circulating pipeline of the water cooling system. Through the gas-liquid separation of the outer water tank cavity and the core body and the gas-liquid separation of the middle converging cavity and the guide pipe, the separation of liquid and gas twice is realized, and no air in the water outlet pipeline is ensured to enter.
3. Through the runner optimal design of the core body, the flow velocity of the core body is reduced, so that gas in the middle converging cavity of the heat exchanger can be automatically discharged back to the cavity of the outer water tank through buoyancy.
4. A part of air is reserved in the outer cavity, so that the volume change generated by expansion and contraction of cooling liquid in the closed circulation system can be changed into the volume change of air, the principle that gas can be compressed is facilitated, the pressure of the system cannot be greatly changed, and the stability of the pressure of the system is maintained.
