Abstract: A heat exchanger and a method of manufacturing the same are provided. With the method, a tube may be inserted into a through hole formed in at least one fin coated with a filler metal, and the tube and a fin collar of the at least one fin may be joined through the filler metal by a brazing processing. A flange may not be formed on or at a top of the at least one fin collar, which protrudes vertically from a central longitudinal plane of the at least one fin. The tube may be made of aluminum (Al), and an interval between an outer circumferential surface of the tube and an inner circumferential surface of the fin collar of the at least one fin may be approximately 0.1 mm or less. Accordingly, contact resistance occurring when fabricating a fin-tube heat exchanger using a mechanical tube expansion method may be reduced, and heat transfer performance of the heat exchanger may be improved because grooves formed within the tube may not be deformed.
Abstract translation: 提供一种热交换器及其制造方法。 利用该方法，管可以插入到形成在涂覆有填充金属的至少一个翅片中的通孔中，并且该管和至少一个翅片的翅片套环可以通过钎焊处理通过填充金属接合。 凸缘可以不形成在从至少一个翅片的中心纵向平面垂直突出的至少一个翅片环的顶部或顶部。 管可以由铝（Al）制成，并且管的外周表面与至少一个翅片的翅片套环的内圆周表面之间的间隔可以为大约0.1mm或更小。 因此，可以减少使用机械管膨胀法制造翅片管式热交换器时发生的接触电阻，并且可以改善热交换器的传热性能，因为形成在管内的槽可能不会变形。
