The temperature control body 11 is used to contact the temperature control 20. The temperature control body 11 is provided with a relatively closed vacuum chamber 111. The wall of the vacuum chamber 111 close to the temperature control 20 is a heat dissipation wall 1111. The wall of the vacuum chamber 111 is There is an injection port 112 and a suction port 113 connected to the outside; the spray assembly 12 is connected to the injection port 112, and the spray assembly 12 is used to atomize the coolant and spray the coolant onto the heat dissipation wall 1111; the suction assembly 13 is connected to the exhaust port 111.

Specifically, the temperature control device 10 provided by the embodiment of the present application can use the suction assembly 13 to suck the gas and/or liquid inside the vacuum chamber 111 through the suction port 113 in advance, thereby causing the vacuum chamber 111 to form a vacuum environment, so as to reduce the subsequent The boiling point of the liquid entering the vacuum chamber 111; when it is necessary to cool the heated control 20, the spray assembly 12 sprays atomized cooling liquid into the vacuum chamber 111 through the injection port 112, especially towards the heat dissipation wall 1111, so that The atomized coolant can absorb the heat of the temperature control 20 and vaporize at low temperature in the vacuum environment of the vacuum chamber 111; then, it is sucked through the suction port 113 by the suction assembly 13 to cool the vaporization and liquefaction inside the vacuum chamber 111. liquid to remove heat. By repeating this cycle, rapid, reliable, and controllable cooling of the temperature control unit 20 can be achieved. In particular, the dosage and frequency of the spray component 12 spraying atomized coolant through the injection port 112 can be controlled to accurately adjust the temperature control unit 20 . cooling temperature of piece 20. Therefore, compared with the prior art, the temperature control device 10 provided in the embodiment of the present application has a better heat exchange effect, that is, a temperature regulation effect, and a higher heat exchange efficiency, that is, a temperature regulation efficiency, for the heated control 20 .

In addition, in the existing technology, in order to ensure smooth flow of coolant, the cooling flow channels of the liquid cooling plate need to be laid out continuously without blind ends, resulting in a long distance between the cooling flow channels and the temperature controlled control 20, causing the liquid cooling plate to have a negative impact on the temperature controlled. The heat exchange effect and temperature adjustment effect of the control 20 are poor. In this regard, the temperature control device 10 provided by the embodiment of the present application, on the basis of ensuring that the vacuum chamber 111 is relatively closed, basically has no other restrictions on the layout of the vacuum chamber 111, so that the vacuum chamber 111 can be close to, close to or even bordering the temperature-controlled environment.

By adopting the above solution, when the vacuum chamber 111 needs to be sucked into a vacuum, the suction assembly 13 can start the vacuum pump 133, so that under the action of the vacuum pump 133, the vaporized coolant and other gases and/or liquefied cooling in the vacuum chamber 111 can be promoted. Liquid such as liquid is sucked into the second pipe 132 through the suction nozzle 131 and flows along the second pipe 132 through the vacuum pump 133 to the end of the second pipe 132 that penetrates into the second liquid storage area 16; subsequently, the second liquid storage Zone 16 can recover vaporized coolant and wait for the vaporized coolant to dissipate heat and liquefy, and/or recover liquefied coolant.
