The existing application number is CN202222170539.4. The tangential plate radiator of the transformer includes a transformer and a radiator arranged on both sides of the transformer. The radiator is fixedly provided with a connecting plate on one side close to the transformer... By setting a fixing mechanism, the plug-in plate is prevented from being dislocated from the connecting plate and the L-shaped plate, the tightness of the connection between the radiator and the transformer is increased, and the displacement of the radiator causes the interface to be dislocated. However, the device is fixedly provided with a plug-in plate that matches the L-shaped plate on both sides of the transformer. It is necessary to first process an additional connection structure on the transformer by welding or other methods to fix the plug-in plate on the transformer. Before installation, additional processing is required to fix the plug-in plate on the transformer, which is not efficient enough and affects the structural strength and appearance of the transformer after processing.
