[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid. They are also called heat exchangers and are widely used in chemical, petroleum, power, food and many other industrial production. Heat exchangers are usually composed of tube bundles, tube sheets and shells. Tube sheets are an important component connecting the tube bundles and shells and play an irreplaceable role. However, the current heat exchanger tube sheets still have the following shortcomings:

[0003] For example, the patent document with application number 202120838255.0 discloses a composite heat exchanger tube sheet. The composite heat exchanger tube sheet uses a tube sheet composed of an anti-corrosion plate and a base plate for use in a heat exchanger, which can achieve an anti-corrosion effect while ensuring the production process and performance of the heat exchanger. However, when fixing the heat exchange tubes, each heat exchange tube needs to be welded to the tube sheet, which is time-consuming and labor-intensive, and the tube sheet has poor strength and is easily damaged during use, resulting in a short service life.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-strength heat exchanger aluminum tube sheet is proposed. Utility Model Content
