In this embodiment, the third heat exchange assembly 120 further includes a second liquid inlet pipe 138, a first switch valve 140, and a second switch valve 142. One end of the second liquid inlet pipe 138 is communicated with the first liquid inlet pipe 122, and the other end of the second liquid inlet pipe 138 is communicated with the first liquid outlet pipe 124, so that the second liquid inlet pipe 138 is installed, and a first medium in the first liquid inlet pipe 122 can enter the first liquid outlet pipe 124 through the second liquid inlet pipe 138. The first switch valve 140 is disposed on the second liquid inlet pipe 138, so that the first switch valve 140 can control the on-off of the second liquid inlet pipe 138. The second switch valve 142 is disposed between the first inlet pipe 122 and one end of the first condenser 126 and one end of the second inlet pipe 138, so that the second switch valve 142 can control the on-off of the pipeline between the first inlet pipe 122 and the first condenser 126. By providing the first switch valve 140 and the second switch valve 142, the first medium can be controlled to flow into the second liquid inlet pipe 138 or the first condenser 126, and the first medium flowing out of the first liquid inlet pipe 122 can be radiated in different manners.

When the temperature outside the machine room is very high, namely the outdoor air temperature T is not less than T2, the first condenser 126 cannot provide refrigerating capacity, and the liquid inlet end of the first condenser 126 can be closed, so that the first medium enters the first liquid discharge pipe 124 through the second liquid inlet pipe 138, and only the third heat exchanger is used for refrigerating the first medium, and then the heat in the machine room is taken away through the third heat exchanger.

Specifically, the first switch valve 140 is a first electric valve, and the second switch valve 142 is a second electric valve, so that the on-off of the pipeline is controlled by adopting an electric valve mode.

In the process of radiating the server 200, the following three radiating modes are included:

In the pure heat pipe mode, the first condenser 126 is a heat pipe condenser, when the temperature outside the machine room is low, namely, the outdoor air temperature T is smaller than T1, the first switch valve 140 is closed, the second switch valve 142 is opened, the outdoor temperature is relatively low, heat in the machine room is taken away completely through the refrigeration cycle of the first condenser 126, the third heat exchanger is not required to be started for supplementing cold circulation, the whole energy consumption unit is less, the energy efficiency of the system is extremely high, and T1 can be adjusted according to specific requirements.

The mechanical compression part cooling supplementing mode, namely the mode that the first heat exchanger 128 supplements the first medium, when the outdoor temperature is relatively high, namely T1 is less than or equal to the outdoor air temperature T < T2, the first switch valve 140 is closed, the second switch valve 142 is opened, the outdoor temperature is relatively high at this moment, after the heat in the machine room is precooled through the first condenser 126, the first heat exchanger 128 is circularly operated to supplement the cooling, and the compressor 132 with the highest energy consumption does not need to be operated under full load at this moment, so that the heat dissipation system still has better energy consumption, and the T1 and the T2 can be adjusted according to the specific requirements.

The mechanical compression complete cooling mode is a mode of only adopting the circulating operation of the first heat exchanger 128 for refrigeration. When the temperature outside the machine room is high, that is, the outdoor air temperature T is not less than T2, the first switch valve 140 is opened, the second switch valve 142 is closed, at this time, the outdoor air temperature is high, the first condenser 126 cannot provide cold, and the heat in the machine room needs to be taken away by the first heat exchanger 128 for cooling circulation. Because the system is close to heating load refrigeration, the refrigerant evaporation temperature in the computer lab is compared with ordinary forced air cooling system and has great promotion, so T2 promotes correspondingly to the grow up when this mode operates and reduces greatly, and whole energy consumption increases limitedly, and T2 can adjust according to specific demand.

Specifically, one side of the first condenser 126 is provided with a first evaporation spraying module, so that the first evaporation spraying module can spray the cooling liquid to the first condenser 126, thereby shortening the cooling time of the first medium and improving the condensation efficiency.

Specifically, the second evaporation spraying module is disposed on one side of the second condenser 130, so that the second evaporation spraying module can spray the cooling liquid to the second condenser 130, thereby shortening the cooling time of the first medium and improving the condensation efficiency.

The heat pipe compression refrigeration integrated machine consists of a heat pipe refrigeration cycle and a mechanical compression cold compensation cycle. The heat pipe refrigeration cycle mainly comprises a first condenser 126 and corresponding pipelines, and when the outdoor temperature is low, the high-temperature gaseous refrigerant evaporated from the indoor is condensed into low-temperature liquid by the heat pipe condenser and then flows back to the indoor cabinet side by gravity; the mechanical compression refrigeration cycle mainly includes a compressor 132, a second condenser 130, an expansion valve 134, a first evaporator 136, and corresponding piping. When the outdoor temperature is higher, the low-pressure refrigerant is compressed into high-temperature high-pressure gas by the compressor 132, then condensed into high-pressure liquid by the second condenser 130, throttled into low-pressure liquid by the expansion valve 134, and then evaporated and absorbed in the first evaporator 136, so as to supplement the cooling of the first medium circulation in the first liquid discharge pipe 124.
