Description

Fin structure of heat exchanger Technical Field The utility model relates to the technical field of heat exchange equipment, in particular to a heat exchanger fin structure. Background The fin type heat exchanger is the most widely used heat exchange equipment in the gas and liquid heat exchanger, achieves the purpose of enhancing heat transfer by additionally arranging fins on a common base pipe, and is widely applied to the fields of air conditioners, refrigerators, automobile heat dissipation systems, industrial cooling and the like. Its main function is to increase heat exchange efficiency by increasing heat exchange surface area, and fin type heat exchanger enhances surface area of heat exchanger by installing fins (sheet metal sheets) on the outer surface of the tube. The fluid flows through the tube and the fins increase the heat exchange by contact with air or other fluid. The prior heat exchange equipment for heat exchangers, pressure vessels and the like is welded and fixed between fins and a base pipe, and a plurality of fins and the base pipe are welded into a whole, so that when a certain fin on a pipe column is impacted to cause bending damage, the heat exchange effect can be affected, and the whole fin pipe can be replaced generally, so that the use cost is increased, a large amount of materials are wasted, and the economic efficiency is lower. Disclosure of utility model The utility model aims to solve the problems that when a fin on a tubular column is bent and damaged due to impact, the whole fin tube can be replaced and the use cost is increased in the prior heat exchange equipment such as a heat exchanger, a pressure vessel and the like because the fin and a base tube are welded and fixed. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a heat exchanger fin structure, includes the semicircle fin of heat exchange tube and cover at its outer wall, be provided with a plurality of equidistance distribution's locating plate on the heat exchange tube, one side of locating plate is provided with the auxiliary positioning subassembly that is used for auxiliary positioning semicircle fin, the both sides outer wall symmetry of heat exchange tube is provided with the fixed establishment who is used for locking fixed semicircle fin. As the further description of the technical scheme, the auxiliary positioning assembly comprises an iron clamping rod fixed on one side of the semicircular fin and a clamping hole formed in one side of the positioning plate and matched with the iron clamping rod, wherein a magnetic block is arranged in the clamping hole, and one end of the magnetic block is magnetically connected with the iron clamping rod. As further description of the technical scheme, the fixing mechanism comprises a fixing block fixed on the outer wall of the heat exchange tube, a through groove is formed in one side of the fixing block, an inserting assembly is arranged in the through groove, and an inserting hole is formed in one side, far away from the iron clamping rod, of the semicircular fin. As further description of the technical scheme, the plug assembly comprises a guide rod fixedly connected inside the through groove, one end of the guide rod is sleeved with a reset spring, one end of the reset spring is movably sleeved with a moving block, one side, away from the reset spring, of the moving block is fixedly connected with the plug rod, and the front face of the moving block is provided with a limiting assembly. As further description of the technical scheme, the limiting component comprises a U-shaped block fixedly connected to the front face of the moving block, the inner wall of the U-shaped block is rotationally connected with a rotating block through a pin shaft, and one side of the rotating block is fixedly connected with an L-shaped limiting block.
