The controller 700 is further configured to determine whether to turn on the second stage cooling device 300 or the heating device 500 according to the first temperature or the second temperature to adjust the temperature of the third coolant output by the heating device 500.
In one embodiment, the specific structure of the first stage cooling device 100 is not limited as long as it has a function of exchanging heat with the first coolant 101. In one embodiment, the first stage cooling device 100 may be comprised of a conventional heat exchanger and a converging three-way valve. In one embodiment, the third coolant in the first stage cooling device 100 exchanges heat with the first coolant 101, and the first temperature is obtained by detecting the temperature of the third coolant output by the power plant 200 in real time through the first temperature detecting device 400. And sending the first temperature to the controller 700, and adjusting the first-stage cooling device 100 through the controller 700 according to the first temperature and a preset target temperature, so that the temperature fluctuation of the third coolant output by the first-stage cooling device 100 tends to be stable.
In one embodiment, the first coolant 101 may be low temperature water and provided through a water chiller. In one embodiment, the second coolant 102 may also be low temperature water and provided by a water chiller. In one embodiment, the third coolant may be tap water. It is to be understood that the specific structure of the power plant 200 is not limited as long as it can provide circulating power to the third coolant. In one embodiment, the power plant 200 may be a pressure pump. In one embodiment, the power plant 200 may also be a conventional water pump.
In one embodiment, the power plant 200 and the first stage cooling unit 100 may be in communication via a conduit.

In one embodiment, the second stage cooling device 300 may be in communication with the power plant 200 via a conduit.
After the temperature fluctuation of the third coolant output by the first-stage cooling device 100 tends to be stable, if the third coolant output by the first-stage cooling device 100 needs to be further cooled and controlled, the second-stage cooling device 300 may be used to perform a second temperature control adjustment on the third coolant. Specifically, the controller 700 and the second temperature detection device 600 may be matched to enable the controller 700 to adjust the second-stage cooling device 300 based on the second temperature and a preset target temperature threshold, so as to realize temperature control adjustment of the third coolant output by the second-stage cooling device 300.
It is to be understood that the specific structure of the first temperature detection device 400 is not limited as long as it has a function of detecting the temperature of the third coolant output from the power unit 200. In one embodiment, the first temperature detection device 400 may be a temperature sensor. In one embodiment, the first temperature detecting device 400 may also be a smart thermometer. The temperature of the third coolant output from the power plant 200 may be obtained in real time by the first temperature detection device 400, and the first temperature may be obtained.
In one embodiment, the first temperature detection means 400 may be provided in a pipe between the power plant 200 and the second stage cooling device 300 as long as it is ensured that the first temperature detection means 400 can detect the temperature of the third coolant. In one embodiment, the first temperature sensing device 400 may also be disposed at an output port of the power plant 200 or an input port of the second stage cooling device 300.
It is to be understood that the specific structure of the heating device 500 is not limited as long as it has a function of heating the third coolant when the third coolant needs to be heated. In one embodiment, the heating device 500 may be a sleeve electric heater. Specifically, the output power of the sleeve electric heater can change in real time along with time, namely, corresponding heating compensation can be carried out on the first temperature. For example: the first temperature is 20+/-1.5 degrees while the target temperature is set to 21+/-0.1 degrees by the controller 700. At this time, the electric heater of the sleeve adjusts the heat value output in real time according to the real-time temperature (i.e. the second temperature) detected by the second temperature detection device 600, so as to meet the final temperature control requirement.
In one embodiment, after the heating device 500 (i.e., the electric sleeve heater) is turned on, the output power of the heating device 500 may also be adjusted by the second temperature and the target temperature threshold acquired by the controller 700 in real time, so as to also achieve the function of adjusting the third coolant temperature output by the heating device 500.
In one embodiment, the heating device 500 and the second stage cooling device 300 can be in communication via a conduit. In one embodiment, the heating device 500 and the first stage cooling device 100 may also be in communication via a conduit. In one embodiment, the specific structure of the second temperature detection device 600 may adopt the structure of the first temperature detection device 400. The temperature of the third coolant output from the heating device 500 may be detected in real time by the second temperature detecting device 600, and the second temperature may be obtained.
In one embodiment, the controller 700 may be a programmable controller. The first temperature is obtained in real time by the controller 700, and is compared with a preset target temperature, and the first-stage cooling device 100 is adjusted based on the comparison result, so that the temperature fluctuation of the third coolant output by the power plant 200 tends to be stable, that is, the temperature fluctuation is controlled within +/-1.5 ℃.
The controller 700 then obtains the second temperature and determines whether to turn on the second stage cooling device 300 or the heating device 500 according to the second temperature and a preset target temperature threshold. Specifically, the preset target temperature threshold may be set according to the requirements of the electronic component 22. For example, the electronic components 22 require a cooling temperature of 21+/-0.1 ℃ and the third coolant output by the first stage cooling arrangement 100 has a temperature of 20+/-1.5 ℃. That is, the second temperature is lower than the preset target temperature threshold, the controller 700 may control the heating device 500 to be turned on (the second stage cooling device 300 and the heating device 500 are turned off by default), and the second stage cooling device 300 is turned off.
That is, the heating device 500 heats the third coolant output by the second-stage cooling device 300, and meanwhile, the heating device 500 can adjust the calorific value output by itself in real time according to the preset target temperature threshold, so as to meet the temperature control requirement of the electronic component 22. It is noted that the second stage cooling device 300 is inactive when the heating device 500 is active. That is, the second stage cooling device 300 is equivalent to a pipe and functions only to transmit the third coolant. Through heating device 500 with second temperature-detecting device 600 with controller 700 cooperation can not only reach the cooling demand to the sensitive electronic part 22 that generates heat of temperature, can also reduce the temperature fluctuation of third coolant realizes the accuse temperature requirement.
In one embodiment, if the required cooling temperature for the electronic components 22 is 19+/-0.1 deg.C, the temperature of the third coolant output by the first stage cooling arrangement 100 is 20+/-1.5 deg.C. That is, the second temperature is greater than the preset target temperature threshold, the controller 700 may control the second stage cooling device 300 to be turned on and the heating device 500 to be turned off. That is, the second-stage cooling device 300 is used to cool down the third coolant output by the power plant 200 again, so as to meet the temperature control requirement of the electronic component 22.
It is noted that the heating device 500 is not in operation when the second stage cooling device 300 is in operation. That is, the heating device 500 corresponds to a pipe and functions only to transmit the third coolant. Through second level cooling device 300 with second temperature-detecting device 600 with controller 700 cooperation can not only reach the cooling demand to the sensitive electronic part 22 that generates heat of temperature, can also reduce the temperature fluctuation of third coolant realizes accuse temperature requirement.
In one embodiment, the controller 700 may also determine whether to turn on the second stage cooling device 300 or the heating device 500 based on the first temperature. Specifically, the controller 700 may compare the first temperature with the preset target temperature threshold, and obtain a comparison result. If the comparison result indicates that the first temperature is greater than the preset target temperature threshold, the controller 700 turns on the second-stage cooling device 300 and turns off the heating device 500. That is, the temperature of the third coolant output from the power plant 200 is reduced again by the second stage cooling device 300. If the comparison result indicates that the first temperature is lower than the preset target temperature threshold, the controller 700 turns on the heating device 500 and turns off the second-stage cooling device 300. Namely, the third coolant output from the second stage cooling device 300 is heated by the heating device 500.
In one embodiment, if the electronic component 22 is not sensitive to temperature fluctuations, the medical device 20 can apply the third coolant from the output of the power unit 200 directly to the electronic component 22. The electronic component 22 sensitive to temperature fluctuation may apply the third coolant output from the output end of the heating device 500 to the electronic component 22.
In this embodiment, the temperature fluctuation of the third coolant output from the first stage cooling device 100 to the power plant 200 is controlled within +/-1.5 ℃ by cooperation of the first stage cooling device 100, the first temperature detection device 400 and the controller 700, and then whether to turn on the second stage cooling device 300 or the heating device 500 is determined by cooperation of the second stage cooling device 300, the heating device 500 and the second temperature detection device 600 with the controller 700 based on the first temperature detected by the first temperature detection device 400 or the second temperature detected by the second temperature detection device 600, so as to adjust the temperature of the third coolant, further reduce the temperature fluctuation of the third coolant, and further achieve the cooling demand of the temperature-sensitive heat-generating electronic component, the temperature control requirement is realized.
Referring to fig. 2, in one embodiment, the second stage cooling device 300 includes: a first heat exchanger 310, a first three-way valve 320. The input end of the first heat exchanger 310 is communicated with the output end of the power device 200. The first heat exchanger 310 is electrically connected to the controller 700. The first heat exchanger 310 is used for heat exchange with the second coolant. A first input of the first three-way valve 320 communicates with an output of the first heat exchanger 310.

The output of the first three-way valve 320 is in communication with the input of the heating device 500. The first three-way valve 320 is electrically connected to the controller 700.
In one embodiment, the first three-way valve 320 is a converging three-way valve. In one embodiment, the first three-way valve 320 and the first heat exchanger 310 may communicate with each other through a pipe. In one embodiment, the controller 700 may determine whether to turn on the first heat exchanger 310 based on the second temperature and the preset target temperature threshold. If the second temperature is greater than the preset target temperature threshold, the controller 700 turns on the first heat exchanger 310, and adjusts the temperature of the third coolant output by the heating device 500 by changing the opening degree of the first three-way valve 320, so as to meet the temperature control requirement of the electronic component 22.

The output of the second three-way valve 120 is in communication with the input of the power plant 200. The second three-way valve 120 is electrically connected to the controller 700. The controller 700 is configured to obtain the first temperature, and determine whether to adjust the opening degree of the second three-way valve 120 based on the first temperature and a preset target temperature.

In one embodiment, the second three-way valve 120 and the second heat exchanger 110 may be in communication via a conduit. In one embodiment, the controller 700 may determine whether to adjust the opening degree of the second three-way valve 120 according to the first temperature and the preset target temperature after acquiring the first temperature.
Specifically, the first temperature may be compared with the preset target temperature, and if the first temperature is lower than the preset target temperature, the opening degree of the second input end of the second three-way valve 120 is closed or decreased. If the first temperature is greater than the preset target temperature, a path between the second three-way valve 120 and the output end of the heating apparatus 500 is closed. I.e. the opening of the bypass of the second three-way valve 120 is closed or reduced, so that more high-temperature coolant enters the heat exchanger for cooling. In this way, the temperature fluctuation of the third coolant output from the first-stage cooling device 100 is stabilized.
