Title:
FINLESS-TYPE HEAT EXCHANGER, OUTDOOR UNIT OF AIR CONDITIONER PROVIDED WITH FINLESS-TYPE HEAT EXCHANGER, AND INDOOR UNIT OF AIR CONDITIONER PROVIDED WITH FINLESS-TYPE HEAT EXCHANGER
Document Type and Number:
WIPO Patent Application WO/2017/159726
Kind Code:
A1
Abstract:
A finless-type heat exchanger (10), having: a pair of headers (2, 3) having tubular parts (20, 30) extending in a first direction and a plurality of branching parts (2a, 3a) formed at predetermined intervals along the first direction on the tubular parts; and a tube group comprising a plurality of flat tubes (1) arranged in the first direction so as to link the branching parts of the pair of headers, the tubes having a flat cross-section that is long in one direction. Two adjacent flat tubes from among the tube group are provided with a channel structure in which the respective flat surfaces of the flat tubes face each other and the respective side surfaces of the flat tubes face a second direction side orthogonal to the first direction. The flat tubes link the branching parts so as to curve in a wave shape, and the side surfaces of the flat tubes as viewed from the second direction have a wave shape. In the tube group, mutually adjacent flat tubes are not in contact with each other, and the both side surfaces of the tube group in the second direction are open so that air flows in from one side surface side and flows out from the other side surface side.
