After the fan 3 is started, the air flow after heat exchange by the heat exchanger 21 flows towards the direction of the fan 3, and during the flowing process, part of the air flow directly flows into the inlet of the fan 3, and part of the air flow flows along the surface of the electric control box 41 to take away the heat released by the circuit board 42 absorbed by the heat dissipation component 43, so that the heat dissipation efficiency of the heat dissipation component 43 is improved.

In an embodiment, the ventilation connection port 132 is further provided with a drainage cover 14, and the cross-sectional area of the drainage cover 14 tends to increase along the air outlet direction.

Specifically, the flow guiding cover 14 is connected to the ventilation connection opening 132 for guiding the airflow output from the fan 3, the flow guiding cover 14 guides the airflow to the air outlet 12 of the casing 1, so as to increase the air outlet coverage area of the air outlet 12, and an air outlet channel is formed by the flow guiding cover 14.

In an embodiment, the surface of the electric control box 41 adjacent to the volute of the fan 3 is a drainage surface 410, the drainage surface 410 is obliquely arranged, the heat dissipation air duct is formed between the drainage surface and the outer wall of the volute of the fan, and the heat dissipation air duct is in a tapered structure along the airflow flowing direction of the heat dissipation air duct.

Specifically, in order to improve the heat dissipation efficiency of the circuit board 42 and improve the operation reliability of the circuit board 42, the surface of the electric control box 41 adjacent to the volute of the fan 3 is a drainage surface 410, so that the airflow is guided to flow through the electric control box 41 by the drainage surface, a heat dissipation air channel is formed between the drainage surface 410 and the volute of the fan 3, and after the fan is started, the airflow after heat exchange by the heat exchanger flows to the fan. Part of the air flow is sucked by the fan, and the other part of the air flow is sucked into the fan after passing through the heat dissipation air duct, so that the heat dissipation treatment can be effectively carried out on the circuit board of the electric control box through the heat dissipation air duct.

In an embodiment, the heat dissipation component is provided with a plurality of heat dissipation fins, and the heat dissipation fins are arranged in an extending manner along the rotating shaft direction of the fan.

Specifically, since the radiating fins are located in the radiating air duct, the extending direction of the radiating fins is the same as the flowing direction of the air flow in the radiating air duct. On one hand, the air flow can flow along the radiating fins in the flowing process of the air flow so as to quickly take away heat, and on the other hand, the radiating fins can guide the air flow so as to ensure the smooth flowing of the air flow in the radiating air duct.

In some embodiments, for the drainage surface 410 formed on the electronic control box 41, the drainage surface 410 may be formed on the box 411. The box 411 is formed with a drainage surface 410, and the drainage surface 410 extends obliquely from the inner wall of the housing 1 along the direction away from the water pan 22. That is, the first end of the drainage surface 410 on the box 411 is close to the side wall of the housing 1 and the water receiving disc 22, and the second end of the drainage surface 410 on the box 411 is far away from the side wall of the housing 1 and the water receiving disc 22.

In some embodiments, the box 411 is further provided with a threading hole, and the threading hole is provided with a threading rubber plug 46 therein. Specifically, the cable that the circuit board 42 in the electric control box 41 stretches out to the outside of the electric control box 41 is led out through the threading rubber plug 46, and the threading rubber plug 46 can seal the led-out part of the cable so as to improve the waterproof performance.

In the description of the above embodiments, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The foregoing is merely illustrative of the present application, and the present application is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present application should be included in the scope of the present application. Therefore, the protection scope of the application is subject to the protection scope of the claims.
