Abstract

To guide lubricating oil flowing into a plate-type heat exchanger to an oil-recovery port, while minimizing the amount of lubricating oil trapped therein.
A plate-type heat exchanger includes: a plate assembly 120 that is a plate stacked body including a stack of a plurality of heat-transfer plates 100; an inlet port and an outlet port for refrigerant 7 provided in the plate assembly 120; an inlet port and an outlet port for water 10 provided in the plate assembly 120; and an oil-recovery port 103e from which lubricating oil 8 contained in the refrigerant 7 is extracted, the oil-recovery port 103e being provided below the outlet port for the refrigerant 7 provided in the lower part of the plate assembly 120. Oil recovery holes 200 communicating with the oil-recovery port 103e are provided at the lower part inside the plate assembly 120, and a flow-smoothing embossed portion 201 is provided on each heat-transfer plate 100 so that the lubricating oil 8 smoothly flows toward the oil recovery hole 200.
