Title: HEAT EXCHANGER AND REFRIGERATION DEVICE
Abstract:
A heat exchanger with excellent efficiency and comprising multiple rows of heat exchange units in which flat pipes circulating a refrigerant are arranged side-by-side is provided. This indoor heat exchanger (25) comprises multiple rows of heat exchange units (50, 60), in which multiple flat multi-hole pipes (45) circulating a refrigerant and extending from a first end to a second end are arranged side-by-side in the vertical direction. In this indoor heat exchanger, the multiple rows of heat exchange units (50, 60) are arranged overlapping in the air flow direction. The number of gas-side flat multi-hole pipes included in the upwind-side, front-row heat exchange unit (50) that have a gas refrigerant port (45aa) provided at one end is less than the number of gas-side flat multi-hole tubes included in the downwind-side, last-row heat exchange unit (60).
