COMBINED HEAT EXCHANGER

摘要

A combined heat exchanger includes a first heat exchanger, a second heat exchanger accommodated in a first tank of the first heat exchanger, and a third heat exchange disposed above or beneath the first heat exchanger. First refrigerant flowing in the first tank exchanges heat with second refrigerant flowing in the second heat exchanger, and the second refrigerant that has exchanged heat flows into a third tank of the third heat exchanger. The second heat exchanger includes a refrigerant flow-in port and a refrigerant flow-out port. The refrigerant flow-in/flow-out ports are disposed at positions opposed to each other on the first tank. The refrigerant flow-out port is connected with the third tank. According to the combined heat exchanger, the refrigerant flow-in/flow-out ports aren't protruded laterally outward from the second heat exchanger, and thereby layout flexibility of the refrigerant flow-in/flow-out ports can be improved.

1. A combined heat exchanger comprising:
a first heat exchanger; a second heat exchanger that is accommodated in a first tank of the first heat exchanger; and a third heat exchanger that is disposed above or beneath the first heat exchanger, wherein first refrigerant flowing in the first tank exchanges heat with second refrigerant flowing in the second heat exchanger, and the second refrigerant that has exchanged heat flows into a third tank of the third heat exchanger, the second heat exchanger includes a refrigerant flow-in port into which the second refrigerant flows and a refrigerant flow-out port from which the second refrigerant flows out, the refrigerant flow-in port and the refrigerant flow-out port are disposed at positions opposed to each other on the first tank, and the refrigerant flow-out port is connected with the third tank.
