热交换器和制造该热交换器的方法
摘要：
提供一种热交换器和制造该热交换器的方法。使用所述方法，管可以被插入形成在涂覆有填充金属的至少一个翅片中的通孔中，以及通过硬钎焊工艺由所述填充金属来结合所述管与所述至少一个翅片的翅片翻边。凸缘可以不形成在所述至少一个翅片翻边的顶部上或所述至少一个翅片翻边的顶部处，所述翅片翻边从所述至少一个翅片的中央纵向平面竖直地突出。所述管由铝(Al)制成，并且所述管的外周面与所述至少一个翅片的所述翅片翻边的内周面之间的间隔可以为大约0.1mm或更小。因此，当使用机械管膨胀方法制作翅片管热交换器时产生的接触热阻可以减小，且因为形成在管内的槽可以不变形所以可以改善热交换器的传热性能。
摘要（英）：

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.
