HEAT EXCHANGER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/205622
Kind Code:
A1
Abstract:
A heat exchanger (1) and an air conditioner. The heat exchanger (1) comprises one or more slit fins (11) and one or more plate fins (12). Each slit fin (11) has one or more through holes for insertion of heat exchange tubes. Adjacent through holes communicate with each other by means of slits, such that air can circulate between adjacent slits of the slit fin (11). Each plate fin (12) has one or more through holes for insertion of heat exchange tubes. Each plate fin (12) is arranged between two or more slit fins (11), such that one or more slit fins (11) between two adjacent plate fins (12) form an air circulation region. Inserting plate fins (12) between slit fins (11) optimizes an air flow path, thereby improving heat exchange performance of a heat exchanger, and increasing heat exchange efficiency.
