The application discloses a manufacturing method of a high-heat-dissipation-efficiency pouring type driving transformer, and belongs to the technical field of power electronic equipment manufacturing. The method aims to solve the technical problems of low heat dissipation efficiency and insufficient long-term reliability of the existing driving transformer caused by the limited heat conduction performance of the pouring material, the simple surface heat dissipation structure and the difficult coordination of internal thermal stress. The method comprises the following steps: constructing a three-dimensional digital model of a reinforced heat dissipation structure with a boss array and a groove array and preparing a corresponding forming die; positioning a magnetic core and a winding as an insert in a die cavity; pouring insulating colloid with different mechanical and heat conduction properties in batches in a vacuum environment; through a segmented curing process, the flexible colloid is fully filled in the internal gap and buffers the stress, and at the same time, the high-heat-conduction rigid colloid forms an external main body and a heat dissipation structure, thereby forming an integrated pouring body. The method is used for manufacturing the driving transformer suitable for high-power-density and high-heat-dissipation scenes, and can significantly improve the heat dissipation capacity and operation reliability of the driving transformer.
