[0002] The electric vehicle controller, as the main control component of the electric vehicle, generates a lot of heat during operation. In order to avoid the internal temperature of the electric vehicle controller being too high and causing damage to its components, the relevant industry often fixes its power tubes on the radiator to achieve heat dissipation. Traditionally, the power tube is directly fixed to the radiator with screws, or the spring is fixed to the radiator and then the power tube is pressed on the radiator through the spring. This part of the structure usually requires machining. However, traditional machining is more likely to produce machining errors during the machining process, and the machining cost is relatively high. Utility Model Content
