Abstract: The present invention provides a power module including a substrate and a modular housing structure. The substrate includes an electronic element disposed thereon. The modular housing structure is disposed on the substrate and located around the electronic element. The modular housing structure includes a plurality of sidewalls configured to connect with each other detachably. Each sidewall includes two connecting elements disposed on two opposite ends thereof respectively. The two connecting elements of any one of the sidewalls are connected to two corresponding connecting elements of two adjacent sidewalls respectively. Consequently, the numbers and connections of the sidewalls are adjustable and varied according to the size of the substrate so as to avoid the waste of space and enhance the power density.
