[0002] The heat exchanger generally includes: a saddle and a flat cover arranged above the saddle, a tube box, a tube sheet, a cylinder and an elliptical head. A number of tube bundles are welded on the tube sheet. Since the tube bundle is arranged in a longitudinal direction, during the process of installing the tube bundle into the cylinder, if the rear end of the tube bundle is not supported by a support, the front end of the tube bundle is at risk of hitting the inner wall of the cylinder, thereby causing damage to the inner wall of the cylinder.
[0003] Existing heat exchanger tube bundle supports mostly use an integral support plate structure, with densely arranged tube holes processed on the metal plate. The number of support plates is set according to the tube bundle length, and the support plate thickness is set according to the tube bundle diameter. When in use, the heat transfer tube passes through the tube holes of each support plate in turn. If the tube bundle size is different, it needs to be re-customized. It will deform and produce errors after long-term use. It has poor compatibility, wastes a lot of resources and is unstable. Utility Model Content
