More Information
Summary:A heat exchanger and a method of manufacturing the same are provided. With the heat exchanger and method of manufacturing, a tube may be inserted into a through hole formed in a fin coated with a filler metal, the tube may be expanded using a tube expansion ball, and the tube and the fin may be joined through the filler metal by brazing processing. The tube may be made of aluminum (Al). An interval between an outer circumferential surface of the tube and an inner circumferential surface of the fin collar before expanding the tube may be approximately 0.1 mm or more, and the tube may be expanded so that the interval between the outer circumferential surface of the tube and the inner circumferential surface of the fin collar is approximately 0.1 mm or less. Accordingly, the heat transfer performance of the heat exchanger may be improved.
