Cooling module

Abstract

A cooling module comprises an intercooler 100 and an integrated heat exchanger 1 including a condenser unit 200 for cooling a refrigerant circulated in a refrigeration cycle by heat exchange between the refrigerant and air and an oil cooler unit 300 for cooling an oil higher in temperature than the refrigerant by heat exchange between the oil and air. Condenser unit 200 and oil cooler unit 300 are vertically arranged in parallel to each other, and integrated heat exchanger 1 is arranged downstream of intercooler 100 in the air flow. The vertical length of integrated heat exchanger 1 is larger than the vertical length of intercooler 100 . Oil cooler unit 300 is arranged in superposition with at least a part of intercooler 100 as viewed from the direction of air flow.
