HEAT EXCHANGER UNIT WITH A VARIABLE CORE CAPABLE OF INCREASING HEAT EXCHANGE EFFICIENCY

摘要

PURPOSE: A heat exchanger unit with a variable core is provided to preferentially cool a radiator requiring high cooling performance.;CONSTITUTION: A heat exchanger unit with a variable core comprises a heat exchanger(1), a reservoir tank, and an actuator module(20). The heat exchanger heat exchanges high temperature cooling water discharged from an engine and an electric device with outdoor air and comprises a core which sends the low temperature cooling water to the engine and the electric device. The reservoir tank sends the high temperature cooling water to the heat exchanger and the low temperature cooling water heat-exchanged by the heat exchanger to the engine and the electric device. The actuator module varies an inflow space of the high temperature cooling water and a discharge space of the low temperature cooling water.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Core position; (BB) Out; (CC) In
