Description

Technical Field

[0002] The air conditioner electronic control box is a device used to control the air conditioner. A certain number of electronic control components are arranged inside the electronic control box. The components inside the air conditioner are connected through the electronic control components to effectively control the corresponding components.

[0003] When electronic control components are installed in an electronic control box, due to the large number of electronic control components and the large number of electronic control component wiring, in order to avoid mutual influence between the electronic control components and the connecting wires, the electronic control components need to be placed in a dispersed manner, so that the layout and wiring settings of the electronic control components are more reasonable.

[0004] Since placing the electronic control components in a dispersed manner will increase the overall volume of the electronic control box, which is not conducive to the rational use of the installation space in the electronic control box, the size of the electronic control box is generally reduced to facilitate installation and effectively save the installation space of the air conditioner. However, after reducing the size of the electronic control box, the electronic control components in the electronic control box will be too close to each other, making it impossible for the heat generated by the electronic control components during operation to be effectively dissipated, thereby causing certain damage to the electronic control components, which is not conducive to the long-term use of the electric control box.
