In the application, the branch hose 3 can be connected in series with the air inlet pipe 21, one end of the air inlet pipe 21 is connected with the branch hose 3, and the other end is communicated with the liquid storage tank 51, so that not only can the liquid drop amount in the refrigerant entering the air inlet pipe 21 be reduced to prevent the liquid impact, but also the vibration of the compressor 5 can be effectively prevented from being transmitted to the branch hose 3.

In some embodiments, the air inlet pipe 21 is communicated with the liquid storage tank 51 of the compressor 5, and a buffer 7 is arranged at the joint of the air inlet pipe 21 and the liquid storage tank 51.

In an embodiment, the substrate 13 adopts an integral structure, and the heat absorbing module 131 and the heat dissipating module 132 are isolated by the heat insulating module, so that a temperature difference can exist between the heat absorbing module 131 and the heat dissipating module 132, and condensation caused by too low temperature of the heat absorbing module 131 is avoided.

In another embodiment, the heat absorbing module 131 and the heat dissipating module 132 are respectively arranged, so that heat exchange between the heat absorbing module 131 and the heat exchanging module is not directly performed, and further, a temperature difference between the heat absorbing module 131 and the heat dissipating module 132 is ensured, and a condensation phenomenon caused by too low temperature of the heat absorbing module 131 is avoided.

In one embodiment, the heat absorbing module 131 of the substrate 13 is attached to the component, and is used as the heat absorbing end 11 to absorb the heat emitted by the component, so that the temperature of the heat absorbing module 131 of the substrate 13 is not too low, and the component is not exposed; in another embodiment, the first end 141 of the heat conducting tube 14 is attached to the component, and is used as the heat absorbing end 11 to absorb the heat emitted by the component, so that the component can be more directly cooled; in yet another embodiment, the heat absorbing module 131 of the substrate 13 and the first end 141 of the heat conducting tube 14 are used together as the heat absorbing end 11 for absorbing the heat emitted by the component.
