The heat absorbing fin group 2 and the heat releasing fin group 3 are connected up and down through the heat pipe body 1, and the heat exchange medium in the heat pipe body 1 is vaporized and rises through the heat absorbing fin group 2 and takes away the heat, and after reaching the heat releasing fin group 3, it is cooled and liquefied by the heat dissipation fan 4 and returns to the heat absorbing fin group 2, and circulates in sequence to realize the heat dissipation of the vacuum water pump.

[0024] like Figure 1 As shown, there are several heat pipe bodies 1 and they are arranged in a horizontal direction in sequence. The heat pipe body 1 is used for heat transfer. The heat pipe body 1 can make the heat exchange medium evaporate at the heat absorbing fin group 2 and then condense at the heat releasing fin group 3, so that the heat is quickly transferred.

[0025] The heat pipe body 1 is in a U-shaped tube with a bend 11, the two closed ends of the heat pipe body 1 are respectively located at the upper end of the heat pipe body 1, and the bends 11 of the heat pipe body 1 are respectively located at the lower end of the heat pipe body 1. The heat exchange medium can be circulated in the heat pipe body 1, saving costs.

[0026] like Figure 4 As shown, the lower end of the heat pipe body 1 and the heat absorbing fin group 2 is the evaporation section 5, and the upper end of the heat pipe body 1 connected to the heat releasing fin group 3 is the condensation section 6, and an insulation section 7 is formed between the evaporation section 5 and the condensation section 6.

[0027] like Figure 1 As shown, the heat absorbing fin group 2 includes a plurality of heat absorbing fins 21 arranged sequentially from top to bottom, one side of the heat absorbing fins 21 is arranged against the outside of the vacuum water pump, the heat pipe body 1 passes through each heat absorbing fin 21, and the heat pipe body 1 and the heat absorbing fins 21 are connected by welding. The heat absorbing fins 21 can increase the heat absorption area, and the heat absorbing fins 21 transfer the heat they contact to the heat pipe body 1, and then the heat pipe body 1 transfers the heat.

[0028] There are five heat absorbing fins 21 arranged at equal intervals. The heat absorbing fins 21 are made of metal aluminum or copper, which can transfer heat to the surface of the heat absorbing fins 21 more quickly, thereby improving heat dissipation efficiency.

[0029] Specifically, the heat dissipation fin group 3 includes a plurality of heat dissipation fins 31 arranged sequentially from top to bottom, the heat pipe body 1 passes through each heat dissipation fin 31, and the heat pipe body 1 and the heat dissipation fin 31 are connected by welding, a heat dissipation channel 32 is formed between two adjacent heat dissipation fins 31, and the heat dissipation fan 4 corresponds to the heat dissipation channel 32. The heat dissipation fan 4 can cool the heat dissipation fin 31 by air, thereby cooling the inside of the heat pipe body 1, and the heat dissipation channel 32 can speed up air circulation to facilitate heat dissipation.

[0030] Furthermore, the number of the heat dissipation fins 31 is 15 and they are arranged at equal intervals, and the heat dissipation fins 31 are made of metal aluminum or copper.

[0031] Furthermore, a liquid wick made of a porous material is provided in the heat pipe body 1. The liquid wick is arranged on the inner wall of the heat pipe body 1, and a heat exchange medium flow channel is formed between the liquid wick and the heat pipe body 1. The heat exchange medium is heated and evaporated to form steam, which moves upward from the middle of the heat pipe body 1, and then cooled and liquefied and falls from between the heat pipe body 1 and the liquid wick, thereby improving the working efficiency.

[0032] Preferably, the total surface area of ​​the heat absorbing fin 21 and the heat radiating fin 31 is 100 cm 2 -100m 2 .

[0033] The principle of this embodiment is:

[0034] The heat absorbing fin group 2 and the heat releasing fin group 3 are connected through the heat pipe body 1. The heat absorbing fin group 2 is used to absorb and transfer heat, and the heat releasing fin group 3 cooperates with the cooling fan to dissipate heat. The heat pipe body 1 has a heat exchange medium inside. The heat exchange medium is affected by the heat absorbing fin group 2, causing the temperature to rise and vaporize, and moves to the heat releasing fin group 3 with heat, and then is cooled and liquefied by the cooling fan 4 and falls to the heat releasing fin group 3, and circulates in sequence to perform heat dissipation work.

[0035] For example:

[0036] Take a certain type of vacuum water pump as an example, its power is 180w, the ultimate vacuum is 0.0974Mpa, the air extraction volume is 10L / min, and the heat generation of the vacuum water pump is about 42J according to the empirical formula. The heat sink is made of aluminum, the specification of a single heat sink is 120mm×120mm, the number of heat sinks is 20, the heat sink used for heat exchange with air is the heat-releasing heat sink 31, the number is 15, and the heat sink used for heat exchange with the heat exchange medium is the heat-absorbing heat sink 21, the number is 5. The air volume Q of the cooling fan 4 is 0.925cmm, and the power is 5w. At room temperature of 25℃, the operating temperature of the vacuum water pump can be controlled at 30℃-35℃ after stable operation for 24 hours. The heat absorbing fin group 2 of the air-cooled heat dissipation device is connected to the vacuum water pump. After the vacuum water pump is started, heat is generated, and the heat is absorbed by the heat absorbing fin group 2 and transferred to the heat pipe body 1. The heat exchange medium in the heat pipe body 1 is vaporized and moves with the heat to the heat releasing fin group 3. Then, the heat releasing fin group 3 is cooled by the cooling fan 4. The heat exchange medium is cooled and liquefied and falls down, and circulates in sequence, so that the heat can be dissipated through the heat pipe body 1, thereby achieving a cooling effect. In this way, the vacuum water pump can be cooled to a set temperature in a short time.
