Title: HEAT EXCHANGER AND METHOD FOR MANUFACTURING SAME
Abstract:
To provide a heat exchanger and a method for manufacturing a heat exchanger, with which it is possible to improve defrosting efficiency and suppress frost formation to a greater extent than in the prior art. A heat exchanger for exchanging heat between internally flowing coolant and peripherally flowing air, wherein: the heat exchanger is provided with a plurality of heat transfer tubes 12 extending in a straight line, and hollow headers 10, 11 into which both ends of each of the plurality of transfer tubes are inserted to constitute a part of a coolant flow route; each of the plurality of transfer tubes has openings 15A–15F at both ends, and internally has a plurality of coolant flow paths 15a–15f through which the coolant flows; and in at least at one end connected to the header in the long direction of the plurality of the heat transfer tubes, the openings 15A–15C provided at some locations including the location positioned farthest to the upstream side of the flow of air are orientated differently inside the header relative to the openings 15D–15F at the remaining locations provided at the one end.
