DEVICE FOR COOLING PARTS OF HEV

摘要

PURPOSE: The whole pressure drop can be reduced through the flow rate distribution of the cooling water. The efficient cooling is included of the structure of being simple. CONSTITUTION: A cooling device of heating element for hybrid electrical vehicles comprises a radiating unit(10). The radiating unit comprises a cooling jacket(11), an inlet(14), and an outlet(15). In the cooling jacket, flow paths(12,13) in which the cooling medium passes by inside the radiating unit is formed. The bottom plate is installed in center and the cooling jacket is classified into the front side and back side. The respective flow path is separately formed in the front side and back side of the cooling jacket. The inlet is formed in the cooling jacket one side. It is communicated with the flow path and the cooling medium flows in. It is communicated with the flow path of the front side and the flow path of the back side and the inlet distributes the cooling medium to the front side and back side. It is communicated with the flow path of the front side and the flow path of the back side and the outlet discharges the cooling medium.
