Title:
HEAT EXCHANGER AND REFRIGERANT CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/018977
Kind Code:
A1
Abstract:
In a heat exchanger (100), a refrigerant flows in the longitudinal direction (DL) between an upper second flow hole (120b) and a lower second flow hole (120b). The heat exchanger (100) comprises a first heat transfer plate (110) and a second heat transfer plate (120) which form N flow channel regions (F1-F5) arranged next to each other in the longitudinal direction (DL). The number and cross-sectional areas of the flow channels in the first flow channel region (F1) are different from the number and cross-sectional areas of the flow channels in the Nth flow channel region (F5). The first flow channel region (F1) is located first among the N flow channel regions in the longitudinal direction (DL) from the upper second flow hole (120b) side. The Nth flow channel region (F5) is located Nth among the N flow channel regions in the longitudinal direction (DL) from the upper second flow hole (120b) side.
