COOLING STRUCTURE OF HIGH VOLTAGE ELECTRIC PARTS FOR HEV

摘要

A cooling structure of high voltage electric parts for a hybrid electric vehicle is provided to improve cooling performance and prevent loss of cooling air by adhering a blower and a duct to high voltage electric parts. A cooling structure of high voltage electric parts for a hybrid electric vehicle cools several high voltage electric parts through air cooling way. The cooling structure of the high voltage electric parts for a hybrid electric vehicle comprises an electric parts package(200) in which several high voltage electric parts and a heat sink are arranged; a blower(270) adhered closely to one side of the electric parts; and a duct(280) integrated with the blower on the upside of the blower. The high voltage electric parts and heat sink is arranged to the flow direction of cooling air regardless of number. The blower cools high voltage electric part. The duct expels the cooling air passing through the electric parts package.
