Title:
HEAT EXCHANGER AND METHOD FOR MANUFACTURING HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2023/166612
Kind Code:
A1
Abstract:
This heat exchanger comprises a plurality of heat transfer tubes extending in a first direction and spaced apart from each other in a second direction intersecting the first direction. The heat exchanger has a first end section and a second end section at both ends in the first direction. The plurality of heat transfer tubes are arranged in m rows (m≥3) in a third direction intersecting the first direction and the second direction. Each of the first end section and the second end section of the heat exchanger is provided with one or more inter-row connection sections that connect two adjacent rows of the heat transfer tubes. In 1≤n≤(m–2), an n-th heat transfer tube and an (n+1)th heat transfer tube are connected with an inter-row connection section therebetween, which is provided at either the first end section or the second end section of the heat exchanger. An (n+1)-th heat transfer tube and an (n+2)-th heat transfer tube are connected with an inter-row connection section therebetween, which is provided at the other of the first end section and the second end section of the heat exchanger. At least one row of the plurality of heat transfer tubes of the heat exchanger has a bent section bent in a third direction at at least one location in the first direction.
