Compact power module for distribution network

The invention relates to a compact power module for a distribution network, and belongs to the technical field of high-voltage direct-current distribution networks. According to the scheme, the power module comprises a box body, the box body comprises an upper panel, a lower panel, a front panel and a rear panel, an air duct cylinder used for ventilating the power module is arranged between the front panel and the rear panel, and an air inlet and an air outlet used for ventilating the air duct cylinder are formed in the connecting position of the front panel and the air duct cylinder and the connecting position of the rear panel and the air duct cylinder respectively. An installation structure used for installing an IGBT assembly is embedded in one end, close to the air inlet, of the air duct cylinder, wherein the two ends of the installation structure are provided with through holes. The scheme of the invention is used for solving the problem that the heat dissipation and maintainability of the converter are
