A self-controlled air-cooled power electronic co-complement module

Abstract

The invention discloses a self-controlling air-cooled power electronic co-complement module, which comprises a fixed base, a support column is symmetrically arranged on the upper end of the fixed base, an installation box is arranged on the top of the support column, and a box cover is arranged on the upper end of the installation box. A heat dissipation shell is provided, the module body is installed in the heat dissipation shell, an insulating heat conducting sheet is provided between the module body and the heat dissipation shell, and a heat absorption cavity is opened inside the heat dissipation shell, and the heat absorption cavity is filled with cooling liquid. In the present invention, the circulation pump, the cooling shell, the heat-absorbing cavity, the cooling liquid, and the structural components such as the first conduit and the second conduit are used to realize the heat absorption of the cooling liquid in a circulating flow type, and achieve self-cooling of the cooling liquid, which can continuously absorb heat. At the same time, when the temperature is too high, the fan extracts the hot air inside the installation box, and then uses the coolant and the heat dissipation block to blow the cooled cold air to the installation box again, achieving the effect of secondary cooling and greatly enhancing the heat dissipation performance.

Problems solved by technology

[0003] Since the electronic power module is a centralized modular design, there are many electronic components, and the heat is relatively large during operation. If the heat dissipation cannot be carried out in time, the electronic components will be damaged. However, the current heat dissipation method is not ideal, so , the present invention provides a self-controlled air-cooled power electronic co-complement module to solve the above-mentioned problems
