Description

technical field [0001] The invention relates to the technical field of novel tubular resistors, in particular to a high-power resistor with a tubular liquid-cooled structure. Background technique [0002] Most of the existing water-cooled resistors adopt a tubular or cylindrical structure, and the two ends of the metal tube or ceramic tube are sealed. The central cavity forms a fluid path, and then the metal wire or metal strip is wound on the outside of the tube wall to form a conductive path. This kind of resistance has a simple structure and is easy to implement, but the water inlet and outlet ports are at both ends of the resistance pipe, which has certain requirements for installation space and pipeline layout. In addition, when using a large pipe diameter or large cylinder diameter for design, due to the large volume of the internal cavity, the internal fluid will accumulate and cannot form turbulent flow, and cannot form a uniform flow. The heat transfer efficiency is...
