摘要:
The present invention provides an apparatus for effectively cooling electric modules such as an inverter and an LDC installed in a hybrid electric vehicle or an electric vehicle. The cooling apparatus for electric modules of a hybrid electric vehicle or an electric vehicle secures a uniform cooling efficiency and achieves an excellent heat radiating efficiency at the same time by realizing a new type of cooling system adapted to separately manage heat transfer in the cooling water passages of first and second electric modules by separating an upper passage of the first electric module and a lower passage of the second electric module using a cooling separator.

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.
