[0024] Embodiment:

[0025] As shown in the attached Figures 1-5 figure

[0026] A unidirectional cyclic refrigerant two-phase change siphon radiator provided with a nano-superconducting alloy mesh according to the present invention comprises an evaporator group composed of a bottom plate 1, a fixing plate 2, a steam generating device 3, a U-shaped gas-liquid separator 4, a nano-superconducting alloy mesh 5, a cover plate 7, an evaporation gas pipe 8 and a liquid guide pipe 9, and further comprises a condenser group composed of a shunt pipe 11, a gas-liquid heat exchange microchannel 12, a confluence pipe 13 and heat dissipation fins 14, wherein: an evaporation gas pipe 10 and a condensate liquid pipe 15 are fixedly installed between the evaporator group and the condenser group, and the evaporation gas pipe 10 and the condensate liquid pipe 15 are communicated with the evaporator group and the condenser group. This application mainly utilizes the heat conduction nanostructure and fast heat conduction property of the nano-superconducting alloy mesh, so that the heat transferred upward by the CPU generates more and smaller microbubbles through the large surface area of this structure. After the microbubbles are generated, they immediately float to the gas pipe for circulation;

[0027] Specifically, the steam generating device 3 and the U-shaped gas-liquid separator 4 are fixedly installed between the bottom plate 1 and the cover plate 7 through the fixing plate 2. The nano-superconducting alloy mesh 5 is fixedly installed in the steam generating device 3. Through the setting of the nano-superconducting alloy mesh 5 and the steam generating device 3, the contact area with the refrigerant can be increased, and the heat exchange efficiency can be improved. The U-shaped gas-liquid separator 4 is on one side of the steam generating device 3. The two side edges of the U-shaped gas-liquid separator 4 are respectively fixedly connected to the bottom plate 1 and the cover plate 7. Through this, the evaporation gas pipe 8 and the liquid guide pipe 9 are fixedly installed on the cover plate 7. One end of the evaporation gas pipe 8 is fixedly connected to one end of the evaporation gas pipe 10, and the evaporation gas pipe 8 is communicated with the evaporation gas pipe 10, so that the evaporation gas enters the condenser group for condensation into liquid. One end of the liquid guide pipe 9 is fixedly connected to one end of the condensate liquid pipe 15, and the liquid guide pipe 9 is communicated with the condensate liquid pipe 15, so that the liquid refrigerant enters the evaporator group;

[0028] Specifically, two gas-liquid heat exchange microchannels 12 are evenly and fixedly installed between the shunt pipe 11 and the confluence pipe 13. The two gas-liquid heat exchange microchannels 12 are respectively communicated with the shunt pipe 11 and the confluence pipe 13.

At the same time, the gas-liquid heat exchange microchannels 12 and the heat dissipation fins 14 can perform air-cooling to reduce the temperature.

[0029] Specifically, a cavity 21 and a liquid inlet 22 are penetrated through the surface of the fixing plate 2 so that the refrigerant can enter and contact the steam generating device 3, and the cavity 21 and the liquid inlet 22 are communicated; a positioning hole 23 corresponding to the positioning column 17 is formed on the surface of the fixing plate 2, and a second positioning column 24 is fixedly installed on the surface of the fixing plate 2; the second positioning column 24 is clamped with the cover plate 7; the positioning column 17 is clamped in the corresponding positioning hole 23; the liquid inlet 22 is communicated with the liquid guide pipe 9 through the cover plate 7; the steam generating device 3 and the U-shaped gas-liquid separator 4 are fixedly installed in the cavity 21, and the U-shaped gas-liquid separator 4 is located between the cavity 21 and the liquid inlet 22, and the U-shaped gas-liquid separator 4 is communicated with the cavity 21 and the liquid inlet 22.

[0030] Specifically, a plurality of liquid channels 31 are uniformly arranged on the bottom surface of the steam generating device 3, and a plurality of U-shaped cavities 32 are uniformly arranged on the upper surface of the steam generating device 3, and the U-shaped cavities 32 are communicated with the liquid channels 31; the liquid channels 31 and the U-shaped cavities 32 are arranged vertically; the nano superconducting alloy mesh 5 is fixedly installed in the corresponding U-shaped cavity 32. Due to the existence of a large number of microstructures, the nano superconducting alloy mesh has a high surface area, greatly increasing the bubble generation points and generating finer bubbles, and accelerating the heat cycle effect of the radiator. This material is not limited to superconducting materials, and the alloy material can be a metal, such as stainless steel, copper, or aluminum.

[0031] Specifically, a plurality of liquid replenishing holes 41 corresponding to the liquid channels 31 are uniformly arranged on one side of the bottom of the U-shaped gas-liquid separator 4, and the liquid replenishing holes 41 are communicated with the liquid channels 31, the cavity 21, and the liquid inlet 22; since the gas density is small and cannot sink and flow backward, the reverse flow of the evaporated gas of the refrigerant can be effectively controlled, and the liquid can replenish the refrigerant liquid through the liquid replenishing holes 41.

[0032] Specifically, a concave cavity 71 and a groove 72 corresponding to the cavity 21 and the liquid inlet 22 are formed on the bottom surface of the cover plate 7, and the concave cavity 71 and the groove 72 are communicated; an evaporation gas outlet 73 is penetrated through the concave cavity 71 of the cover plate 7, and the evaporation gas pipe 8 is communicated with the evaporation gas outlet 73 so that the evaporation gas can enter the evaporation gas pipe 8, and a condensate liquid inlet 74 is penetrated through the groove 72 of the cover plate 7, and the condensate liquid inlet 74 is communicated with the liquid guide pipe 9 so that the liquid refrigerant can enter; a second positioning hole 75 corresponding to the second positioning column 24 is formed on the surface of the cover plate 7, and the second positioning column 24 is clamped in the corresponding second positioning hole 75; the upper half parts of the steam generating device 3, the U-shaped gas-liquid separator 4, and the nano superconducting alloy mesh 5 are located in the concave cavity 71, and the U-shaped gas-liquid separator 4 is located between the concave cavity 71 and the groove 72.

[0033] In this embodiment, the evaporator group is fixedly installed on the CPU through the bottom plate 1. After the heat comes from the CPU, it is transmitted upward through the bottom plate 1 to the steam generating device 3. Therefore, the heat is introduced into the nano-superconducting alloy mesh 5 from the lower, left, and right sides of the U-shaped cavity 32. By means of the highly extended surface area of the microstructure of the nano-superconducting alloy mesh 5, more bubble generation points are provided, and at the same time, the generation of large bubbles is suppressed. After the micro-bubbles are generated, they immediately float to the gas pipe and circulate in the siphon radiator, increasing the heat dissipation efficiency.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
