Inventor: ZHOU DEWEI
IPC: H05B3/68
Filed: 2019-04-08
Abstract: The present utility model relates to a brazed aluminum alloy composite bottom plate and a heating coil.
An aluminum alloy composite bottom plate uses 1000, 3000 or 6000 series aluminum alloy as a substrate, and then a 4000 series aluminum-silicon alloy double-sided metallurgical composite is formed, the ratio of the thickness of a single-layer 4000 series aluminum-silicon alloy to the thickness of the total composite substrate being 5-15%;
a heating coil is formed by being brazed by a heat pipe, the aluminum alloy composite bottom plate, and a chassis.
The utility model causes brazing welding metallurgical quality to be high, eliminates the metallurgical looseness of brazing, and greatly improves the heat transfer efficiency of a heating pipe to a stainless steel or an aluminum alloy by means of the aluminum alloy bottom plate. In addition, the aluminum alloy has a high recovery rate, thereby reducing the use of flux and being beneficial in environmental protection. Compared with single aluminum alloy solder powder, aluminum solder paste or solder sheet brazing techniques, the heating coil brazed and manufactured by using the aluminum alloy composite bottom plate may reduce the coating amount; in addition, coating a brazing flux is simple and convenient, and the number of operators may be reduced, achieving automatic brazing flux coating.
