Electrical box and air conditioner

Abstract

The invention provides an electrical box and an air conditioner. The electrical box comprises a box body and an electrical component module located in the box body. The box body is provided with an airflow inlet, a flow guiding air duct is formed between the airflow inlet and the electrical component module, and the flow rate of airflow entering from the airflow inlet can be increased through theflow guiding air duct. According to the electrical box and the air conditioner, the heat dissipation efficiency of large-power components in the electrical box can be obviously improved, the temperature of the components is decreased, and the stability and reliability of the components are improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an electrical box and an air conditioner. Background technique [0002] The electrical box is widely used in air conditioners, and it is mainly used as a carrier for electrical components, so that the electrical components can be isolated from the external environment to achieve dustproof and waterproof effects. However, there are high-power components in the current electrical components, such as common traditional semiconductor material IPM modules and PFC modules, which generate relatively large heat and generate a lot of heat during operation, requiring heat dissipation. At present, the heat dissipation method for such high-power components is mostly forced air-cooled heat exchange. Specifically, air inlets and air outlets are set on the box body of the electrical box, and then corresponding air inlets and / or outlets are set. fan, so as to realize the fo...

Problems solved by technology

At present, the heat dissipation method for such high-power components is mostly forced air-cooled heat exchange. Specifically, air inlets and air outlets are set on the box body of the electrical box, and then corresponding air inlets and / or outlets are set. fan, so as to realize the forced flow of airflow, and then realize the effect of forced heat exchange, but because the components of the electrical box include high-power components and other components with relatively small heat dissipation requirements, the current way, the entrance After the fan introduces the airflow into the electrical box and diffuses it rapidly, only part of the electrical components dissipate heat, that is, the cooling airflow lacks pertinence to high-power components. Therefore, the heat exchange and cooling effect on high-power components is insufficient. Good, needs to be improved
