Novel aluminum heating ring and manufacturing method thereof

Abstract

The invention provides a novel aluminum heating ring and a manufacturing method thereof. The novel aluminum heating ring comprises a heating tube and two semicircular annular heating rings, wherein each semicircular annular heating ring comprises an outer ring, an inner ring and a heat conduction ring; the outer ring, the inner ring and the heat conduction ring are all made of aluminum calenderedplates, and a groove is formed in the inner side surface of the outer ring; the heating tube is arranged in the groove; the heat conduction rings are distributed in a spaced mode along the circumferential direction of the inner ring; lugs are arranged on the circumferential end face of the outer ring; fastening holes are formed in the lugs; and an aluminum brazing layer is arranged between the outer side of the heat conduction ring and the inner side of the inner ring, between the outer side of the inner ring and the inner side of the outer ring, and between the heating tube and the groove. The manufacturing method comprises the following steps of manufacturing the outer rings, the inner rings and the heat conduction rings, preparing a brazing flux solution and a brazing flux material mixture, coating the brazing flux material, and carrying out assembling, brazing, appearance processing, and wiring end assembling or welding. The invention aims to provide the novel aluminum heating ringwith high heat conduction efficiency, no pollution in the manufacturing process, simplicity in manufacturing and low cost, and the manufacturing method of the novel aluminum heating ring.

Description

technical field [0001] The invention relates to a novel aluminum heating ring and its manufacturing method, specifically, a novel aluminum heating ring made of aluminum rolling plate and its manufacturing method. Background technique [0002] Aluminum heating ring is generally composed of heating tube and cast aluminum parts. The general molding method is to place the manufactured heat pipe in the clay mold cavity, and then inject molten aluminum alloy slurry into the clay mold cavity to cast it. Since there is no pressure during the casting process, the cast aluminum heating ring has a loose structure, low density, and low heat transfer capacity. Moreover, the machining workload of the cast aluminum heating ring is large, resulting in high costs. In addition, the pollution of the foundry process is very serious, and it is a pollution problem under the national key monitoring. If precision die-casting is used, although the above-mentioned problems can be perfectly solved,...
