Title:
HEAT EXCHANGER, FIN TUBE MANUFACTURING METHOD, AND HEAT EXCHANGER MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/103180
Kind Code:
A1
Abstract:
The present invention relates to a heat exchanger comprising multiple arranged fin tubes, each of which comprises a heat transferring fin and multiple tubes integrally formed on a plate, wherein refrigerant flows through the tubes. Each of the fin tubes has a first surface forming the front surface of the fin tube and a second surface forming the rear surface of the fin tube, and has opening part which communicates with at least a side of the multiple tubes and is formed to extend through the first surface and the second surface; and the perimeters of the openings of the fin tubes adjacent to each other may be connected through a connection part such that the openings of the adjacent fin tubes communicate with each other. Therefore, there is an advantage in that refrigerant can be distributed without a separate header.
