Abstract
This utility model relates to the field of module heat dissipation technology, and discloses a heat dissipation structure for a power module, including a motherboard. A heat transfer layer is fixedly connected to the bottom of the motherboard, and a heat dissipation base is slidably connected to the bottom of the heat transfer layer. A housing is fixedly connected to the bottom of the heat dissipation base, and a heat dissipation component is installed on the bottom of the housing. In this utility model, the housing provides support for the cooling fan, filter plate, and filter screen, enabling them to operate stably. The cooling fan dissipates heat from inside the housing, while outside air enters the housing through the filter screen. The filter plate and filter screen filter dust and impurities, thereby allowing the interior of the housing and the heat sink to cool down rapidly. This dissipates the heat generated by the power module during operation, ensuring stable operation and improving the working efficiency of the power module.
