[0027] So that the traditional water cooling system can circulate the water in different systems with the help of the circulating pump thrust, such as the car water cooling system cooling the engine, the computer server cooling chip and so on.

[0028] Specifically, the limiting plate 2 is fixedly mounted on the bottom plate 1, the steam generating device 3 and the U-shaped gas-liquid separator 4 are fixedly mounted in the limiting plate 2, the limiting plate 2 is fixedly connected to the cover plate 5, the steam generating device 3 and the U-shaped gas-liquid separator 4 are located inside the cover plate 5, the liquid guide pipe 7 and the gas guide pipe 8 are fixedly mounted on the cover plate 5, the U-shaped gas-liquid separator 4 is located on one side of the steam generating device 3, and the two sides of the U-shaped gas-liquid separator 4 are respectively fixedly connected to the bottom plate 1 and the cover plate 5; so as to seal the steam generating device 3 and form a closed space required for evaporation;

[0029] Specifically, two gas-liquid heat exchange microchannels 11 are fixedly installed between the shunt pipe 10 and the confluence pipe 12, and the gas-liquid heat exchange microchannels 11 are connected with the shunt pipe 10 and the confluence pipe 12, and the heat dissipation fins 16 are fixedly installed on the surfaces of the two gas-liquid heat exchange microchannels 11; so that the gaseous refrigerant enters the two gas-liquid heat exchange microchannels 11 through the evaporating gas pipe 9 and the shunt pipe 10 respectively to be cooled and turned back into liquid;

[0030] Specifically, the liquid outlet of the circulation pump 14 is fixedly connected to one end of the delivery pipe 15, the other end of the delivery pipe 15 is fixedly connected to the liquid guide pipe 7, the liquid inlet of the circulation pump 14 is fixedly connected to one end of the return pipe 13, the other end of the return pipe 13 is fixedly connected to the manifold 12, one end of the evaporation gas pipe 9 is fixedly connected to the air guide pipe 8, and the other end of the evaporation gas pipe 9 is fixedly connected to the diversion pipe 10; so that the liquid refrigerant inside the condenser group can be transported to the evaporator group through the circulation pump 14 to continue the heat exchange.

[0031] Specifically, an evaporation chamber 21 and a liquid inlet 22 are opened on the limit plate 2, and the liquid inlet 22 is connected to the evaporation chamber 21, so that the liquid refrigerant enters the evaporation chamber 21 and contacts the steam generating device 3 for heat exchange; the steam generating device 3 and the U-shaped gas-liquid separator 4 are fixedly installed in the evaporation chamber 21, and the U-shaped gas-liquid separator 4 is between the steam generating device 3 and the liquid inlet 22; the liquid inlet 22 is connected to the liquid guide pipe 7 through the cover plate 5.

[0032] Specifically, a plurality of channels are opened through the interior of the steam generating device 3 to increase the contact area with the liquid refrigerant, thereby improving the heat exchange efficiency, and four liquid channels 31 are evenly distributed on the bottom surface of the steam generating device 3, and an evaporation channel 32 is opened on the upper surface of the steam generating device 3; the channels are connected with the liquid channels 31 and the evaporation channels 32, and the channels are vertically arranged with the liquid channels 31 and the evaporation channels 32; the liquid channel 31 is connected with the evaporation chamber 21, and the liquid channel 31 is connected with the liquid inlet 22 through the U-shaped gas-liquid partition plate 4; the evaporation channel 32 is connected with the air duct 8 through the cover plate 5.

[0035] In this embodiment, this application mainly uses the active circulation characteristics of the circulating pump to bring the heat absorbed from the heat source to the condensation end, condenses most of the gas into liquid after condensation, and uses the active stacking force of the circulating pump to overcome the height difference and inclination of the evaporator and condenser, and adjusts the thrust to achieve the best heat exchange.

[0036] Technical features:

[0037] A. Liquid refrigerant absorbs heat from the evaporator, turns into gas and is then transferred to the condenser. After the refrigerant condenses into liquid, it is pushed back to the evaporator through the refrigerant circulation pump. The flow rate of the circulation pump can be adjusted to achieve the best heat exchange efficiency.

[0038] B. Figure 1 As shown, under the active stacking force of the refrigerant circulation pump, the design of the pipeline will not be limited by circuit conditions such as long distance, many bends and height difference. The designer can give priority to the customer's space.

[0039] C. Compared with common siphon radiators, if the product is tilted or the evaporator and condenser are not at the same level (depending on the situation), problems may occur in the transmission of gas to the condenser or the return of liquid to the evaporator, thus affecting performance; using a circulating pump can greatly overcome this problem.
