摘要： A cooling apparatus of a power module includes a guide provided inside a manifold cover to control a flow of a cooling fluid, wherein the cooling fluid circulated inside the manifold cover forms a vertical turbulent flow by the guide so that cooling efficiency of the power module is secured only using an internal structure of the manifold cover. Thus, heat dissipation performance is improved without a separate fin plate or a separate nozzle injection device.
