AI Technical Summary

Technical Problem

Duct-type indoor units lack independent and dedicated heat dissipation fins in their electrical boxes, resulting in poor heat dissipation and complex and costly on-site installation procedures.

Method used

Heat dissipation fins are integrated inside the electrical box, and an independent circulating heat dissipation air duct is set up. A circulating heat dissipation path is formed through the first heat dissipation air inlet, the second heat dissipation air inlet, and the heat dissipation air outlet, eliminating the need for on-site installation procedures.

Benefits of technology

It significantly improves the heat dissipation effect of the heat sink fins, reduces costs, improves the overall heat dissipation effect of the electrical box, and simplifies the installation process.

Abstract

The application discloses a duct type indoor unit, a mounting cavity is formed in a shell; a support plate is arranged in the mounting cavity, the support plate separates the mounting cavity into a front mounting cavity and a rear mounting cavity; a first air inlet for heat dissipation is arranged on the support plate; an electric appliance box is arranged in the rear mounting cavity; the electric appliance box comprises a box body, a second air inlet for heat dissipation is arranged on a wall of the box body on a side facing the support plate, the second air inlet for heat dissipation is communicated with the first air inlet for heat dissipation, a heat dissipation air outlet is arranged on a wall of the box body on a side facing the rear mounting cavity; a substrate is arranged in the box body; heat dissipation fins are connected with the substrate and located in the box body; air in the front mounting cavity enters the box body through the first air inlet for heat dissipation and the second air inlet for heat dissipation, and after heat exchange with the heat dissipation fins, the air enters the rear mounting cavity from the heat dissipation air outlet. The heat dissipation structure of the electric appliance box is improved, and the heat dissipation effect of the electric appliance box is improved.
