Title:
HEAT DISSIPATION APPARATUS, INVERTER AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/017312
Kind Code:
A1
Abstract:
Disclosed in the present application are a heat dissipation apparatus, an inverter and an electronic device. The heat dissipation apparatus comprises a main heat radiator, an expansion heat radiator, and a heat conduction member. The main heat radiator comprises a main substrate and main heat dissipation teeth, with one end of each main heat dissipation tooth being connected to the main substrate; the expansion heat radiator is located at the end of each main heat dissipation tooth away from the main substrate; the expansion heat radiator is detachably connected to the main heat radiator; and the heat conduction member extends from the main substrate to the expansion heat radiator so as to conduct heat between the main substrate and the expansion heat radiator. In the present application, the heat dissipation apparatus is designed to have a split structure, the double heat dissipation effects of the main heat radiator and the expansion heat radiator improve the heat dissipation capability of the heat dissipation apparatus and improve the heat dissipation efficiency, and in addition, the expansion heat radiator is detachably connected to the inverter on which the main heat radiator is mounted, such that a flexible configuration is achieved, and the problem of difficulties occurring during transportation, mounting and maintenance is avoided.
