Brazed aluminum heat exchanger |
摘要 |
An aluminum heat exchanger is provided. In one embodiment, the aluminum heat exchanger comprises a fin having a first aperture therethrough with a flange formed around the first aperture. The fin is made from a first alloy having a first melting point. The heat exchanger includes a refrigerant tube made from a second alloy having a second melting point. The refrigerant tube extends through the first aperture. The heat exchanger also has a tubular coupling made from a third alloy having a third melting point and that is coupled to an end of the refrigerant tube. A fourth alloy having a fourth melting point less than the first, second, and third melting points is interposed the refrigerant tube and the flange, and further interposed the refrigerant tube and the tubular coupling. A method of manufacturing and a refrigeration unit are also provided.
