LAMINATE-TYPE HEAT EXCHANGER AND HEAT PUMP SYSTEM EQUIPPED WITH SAME

摘要

Provided is a laminate-type heat exchanger that requires no bending process for a heat transfer pipe and has no dead space caused by a header pipe, and also provided is a heat pump system equipped with the laminate-type heat exchanger. A heat exchanger (10) has a construction in which a plurality of first heat transfer pipes (1) and second heat transfer pipes (2) having a rectangular shape are stacked alternately. The first and second heat transfer pipes comprise refrigerant passages having rectangular cross sections through which a refrigerant flows, wherein the refrigerant passages have substantially the same length in the direction in which the refrigerant flows, and substantially the same length in the width direction of the refrigerant passages.
