Self-control air-cooled power electronic co-compensation module

Abstract

The invention discloses a self-control air-cooled power electronic co-compensation module which comprises a fixed base, supporting columns are arranged at the upper end of the fixed base in a bilateral symmetry mode, a mounting box is arranged at the tops of the supporting columns, a box cover is arranged at the upper end of the mounting box, a heat dissipation shell is arranged in the mounting box, a module body is mounted in the heat dissipation shell, and an insulating heat-conducting sheet is arranged between the module body and the heat dissipation shell. A heat absorption cavity is formed in the heat dissipation shell and filled with cooling liquid. Circulating flowing type heat absorption of the cooling liquid is achieved through structural components such as the circulating pump, the heat dissipation shell, the heat absorption cavity, the cooling liquid, the first guide pipe and the second guide pipe, self-cooling of the cooling liquid is achieved, continuous and good heat absorption can be achieved, meanwhile, when the temperature is too high, the draught fan extracts hot air in the mounting box, and the cooling liquid and the heat dissipation block are reutilized; and thecooled cold air is blown to the mounting box again, so that the secondary cooling effect is achieved, and the heat dissipation performance is greatly enhanced.

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
