<p>PROBLEM TO BE SOLVED: To provide a complex type heat exchanger capable of efficiently cooling a high electrical current type appliance while cooling air-conditioning coolant before the same flowing into an air-cooled condenser.SOLUTION: A complex type heat exchanger 1 comprises: a sub-radiator 20 which cools cooling water passing through a high electrical current type appliance 3; an air-cooled condenser 40 which cools an air-conditioning coolant different from the cooling water; and a water-cooled condenser 30 which exchanges heat between the cooling water and the air-conditioning coolant. The sub-radiator 20 has a first heat exchange section 20A and a second heat exchange section 20B. The cooling water cooled by the first exchange section 20A exchanges the heat with the air-conditioning coolant in the water-cooled condenser 30. The cooling water which exchanges the heat inside the water-cooled condenser 30 exchanges the heat in the second heat exchange section 20B. Then the cooling water which exchanges the heat in the second heat exchange section 20B is used for cooling the high electrical current type appliance 3.</p> |
