HEAT EXCHANGER, AND HEAT PUMP DEVICE

摘要

This heat exchanger is provided with: a plurality of thin-plate members (1) which are disposed with a clearance therebetween, which have a fluid flowing therebetween, and in which passages are formed, said passages having, flowing therethrough, a medium for performing heat exchange with the fluid; and a pair of headers which respectively connect both ends of the plurality of thin-plate members (1). In cases when Fp is the clearance between neighbouring thin-plate members (1), and Ft is the thickness of the thin-plate members (1), the plurality of thin-plate members (1) satisfy the relationship 3 ≤ Fp/Ft ≤ 21.
