The temperature/humidity sensor may be disposed inside the target device 17, or may be disposed at any position outside the target device 17, but needs to be disposed close to the target device 17.
As shown in fig. 2 and fig. 3, the present invention further provides a heat dissipation apparatus, which includes a cooling module 300 and a refrigeration control system; the refrigeration control system is used for controlling the cooling module 300 to cool down the target device 17.
The cooling module 300 comprises a liquid circulation submodule for cooling the target device 17 and a refrigeration circulation submodule for refrigerating liquid in the liquid circulation submodule;

The refrigeration assembly comprises at least two refrigerant radiators 4 connected in series and at least two heat dissipation structures 3, and the heat dissipation structures 3 dissipate heat for the refrigerant radiators 4. Through setting up a plurality of refrigerant radiators 4 in series, the heat radiating area that has increased refrigerant radiator 4 in limited space refrigerant flows in refrigerant radiator 4, passes through a plurality of refrigerant radiators 4 that set up in series in proper order, and the amount of wind that is produced by heat radiation structure 3 can directly act on refrigerant radiator 4, has improved refrigeration effect.

Similarly, three fans are connected in series for description, and the wind pressure generated by the three fans can be three times of that generated by one fan at the rotating speed, so that the purpose of reducing noise is achieved, and a high heat dissipation effect is achieved.

The specific setting is set according to actual needs.
When the inverter compressor 8 is adopted, the rotating speed of the inverter compressor 8 can be directly adjusted, and low-rotating-speed starting is realized, so that the starting noise of the heat dissipation device of the target equipment 17 is reduced; meanwhile, when the thermal load of the target equipment 17 is low, the inverter compressor 8 is operated at a low rotation speed, thereby reducing the noise of the start of the heat sink of the target equipment 17.
