AI Technical Summary

Technical Problem

The vertical arrangement of the heat dissipation duct of the existing air conditioner outdoor unit causes dust to accumulate under the circuit board, affecting the reliability of the circuit board and potentially causing localized overheating of the circuit board and interference with the internal structure of the air conditioner outdoor unit.

Method used

A horizontally arranged heat dissipation channel is set inside the electrical control box, and the air inlet is located on the side of the circuit board to avoid dust accumulation. The horizontal airflow also prevents heat from accumulating in the vertical direction. At the same time, heat exchange is carried out using a heat dissipation module to achieve uniform heat dissipation of the circuit board.

Benefits of technology

This effectively prevents dust accumulation, ensures the reliability and uniform heat dissipation of the circuit board, avoids interference between the electrical control box and the internal structure of the outdoor unit of the air conditioner, and improves the heat dissipation efficiency and service life of the circuit board.

Abstract

The application provides an electric control box assembly, an air conditioner outdoor unit and an air conditioner. The electric control box assembly comprises: an electric control box, which has a heat dissipation flow channel inside, and a communication port, an air inlet and an air outlet are arranged on the surface of the electric control box and communicate with the heat dissipation flow channel; a heat dissipation module, which is installed in the heat dissipation flow channel and at least partially faces the communication port; and a circuit board, which covers the communication port and contacts the heat dissipation module; wherein the air inlet is arranged along one side height edge of the circuit board, and the heat dissipation flow channel extends towards the other side height edge of the circuit board. The application makes the airflow entering the heat dissipation channel uniformly distributed at the height edge of the circuit board, and the dust in the airflow can naturally settle along the height edge of the circuit board, thereby avoiding the phenomenon that the dust in the airflow is deposited on the components and devices below the circuit board.
