The heat radiating plate 10 is used for connecting a control panel of an air conditioner external unit. The heat sink 10 is connected to the control board, and absorbs heat generated from the control board, and emits the heat to the air, or absorbs the heat by other structures. Alternatively, the heat dissipation plate 10 is made of aluminum to effectively conduct heat of the control board and to be released or absorbed.
In addition, a control chip is provided on the control board, the control chip is a main location for generating heat generated by the control board, and the heat dissipation plate 10 is actually connected to the control chip to achieve effective heat conduction.
In an embodiment of the present invention, the heat dissipation plate 10 includes a plurality of heat dissipation fins arranged at intervals, and is adjacent to the heat dissipation fins with heat dissipation gaps therebetween.
By providing a plurality of heat dissipation fins arranged at intervals, the contact area between the heat dissipation plate 10 and the air can be increased, and the heat dissipation efficiency can be improved. Specifically, the method comprises the following steps. The heat sink 10 further includes a contact portion connected to the control board, and the plurality of heat dissipation fins are arranged at intervals on the contact portion.
The evaporation flow path 20 is provided on the heat sink 10, and both ends of the evaporation flow path 20 are connected to a refrigerant circulation line of an air conditioner, respectively. So that the refrigerant in the air conditioner refrigerant circulation line flows into the evaporation flow path 20 from the first end of the evaporation flow path 20, and returns to the air conditioner refrigerant circulation line again from the second end of the evaporation flow path 20.
Thus, a part of the refrigerant on the refrigerant circulation line flows to the evaporation flow path 20, and the evaporation flow path 20 is disposed on the heat dissipation plate 10, so that the part of the refrigerant evaporates and absorbs heat, thereby enhancing the heat dissipation function of the heat dissipation plate 10. The refrigerant that has absorbed heat and has changed into a gaseous state also flows back to the refrigerant circulation line. It should be noted that, since the heat dissipation plate 10 is very small, the amount of the refrigerant flowing into the evaporation flow path 20 is very small, and the evaporation flow path 20 is a pocket-sized evaporator, the cooling effect of the internal evaporator 50 is not affected, and thus the cooling effect in the room is not affected.
In this embodiment, the first end of the evaporation flow path 20 is connected to the outlet of the condenser 30, the second end of the evaporation flow path 20 is connected to the inlet of the compressor 40, that is, the return pipe of the refrigerant circulation line, the refrigerant in the condenser 30 becomes liquid after releasing heat, the heat of the heat dissipation plate 10 is absorbed by the evaporation flow path 20 to become gaseous, and then the gaseous refrigerant enters the return pipe and is mixed with the gaseous refrigerant in the refrigerant circulation line, so as to realize circulation.

In the foregoing embodiment, the heat dissipation plate 10 includes a plurality of spaced fins, and the evaporation flow path 20 is disposed in the heat dissipation gap.
Since the heat dissipation plate 10 dissipates heat at the heat dissipation fins, the evaporation flow paths 20 are disposed in the heat dissipation gaps, which further improves the heat dissipation effect of the heat dissipation plate 10.
Specifically, on the basis that the evaporation flow path 20 is coiled in the heat dissipation plate 10, here, the evaporation flow path 20 is coiled in a plurality of heat dissipation gaps, that is, the evaporation flow path 20 extends from the first end to the second end of the heat dissipation plate 10 along the heat dissipation gap, and then bends vertically along the extending direction of the first end to the second end of the heat dissipation plate 10, and returns to the first end from the second end of the heat dissipation plate 10 along the adjacent heat dissipation gap, and further bends vertically along the extending direction of the first end to the second end of the heat dissipation plate 10, and so on, so as to realize that the evaporation flow path 20 is coiled in the heat dissipation gap, and improve the heat dissipation effect of the heat dissipation plate 10. Further, the evaporation flow path 20 may be arranged in each of the heat dissipation gaps in a winding manner, or may be arranged in each of the heat dissipation gaps in a winding manner, and the evaporation flow path 20 may be arranged in an adjacent heat dissipation gap in a winding manner.
Optionally, in order to further increase the heat dissipation effect, when the evaporation flow path 20 is disposed in the heat dissipation gap, the evaporation flow path 20 is in contact with both the adjacent two heat dissipation fins, and when the refrigerant flows along the evaporation flow path 20, the heat absorption effect is better because the heat absorption is performed on the heat dissipation fins on both the adjacent sides at the same time.
