The present invention provides an apparatus for cooling parts of a hybrid electric vehicle. The apparatus cools the main heating parts of a motor driving system, including an inverter, in the HEV. A heat dissipater may also be provided and equipped with different heating parts, such that the heating parts share the heat dissipater. A channel for a coolant to flow is formed in the heat dissipater, and the heat dissipater defines heat transfer paths for transferring heat generated from the heating parts to the coolant. The heating parts include a power module, an inductor, and a film capacitor.
