AI Technical Summary

Technical Problem

The current air conditioner control board has an unreasonable component layout, resulting in low heat dissipation efficiency of heat-generating components and an inability to meet the control requirements of higher frequencies and performance.

Method used

The base plate of the electronic control board is divided into multiple mounting areas, where the main control chip circuit, active power factor correction control circuit, frequency conversion control circuit and power input circuit are laid out respectively. Power devices with large heat generation are reasonably distributed to enhance heat dissipation. Passive components are connected through copper lines to optimize the layout design.

Benefits of technology

The heat dissipation efficiency of the control board has been improved, the overall size has been reduced, and the installation flexibility and assembly efficiency of the control board have been enhanced, making it suitable for control requirements with higher frequencies and performance.

Abstract

The invention discloses an electric control board, an air conditioner outdoor unit and an air conditioner, and belongs to the technical field of household appliances. The electric control board is divided into a first mounting area, a second mounting area, a third mounting area and a fourth mounting area; the main control chip circuit, the active power factor correction control circuit, the frequency conversion control circuit, the power input circuit and the functional interface circuit are respectively mounted in different mounting areas; as the partition installation is adopted, the main control chip circuit is arranged on one side of the substrate, namely the edge position close to the substrate, and the passive components are arranged around the control chip or the passive components are intensively arranged on one side of the control chip, the heat generated by the control chip can be dissipated more easily, and the heat dissipation efficiency is improved. Heat interference generated between the electronic control board and devices in other installation areas is reduced, the heat dissipation efficiency is improved, and the electronic control board can adapt to the control requirements of higher frequency and performance.
