[0002] Tubular heat exchangers (also known as shell and tube, tube-in-tube) are the most typical wall-type heat exchangers. They have a long history of industrial application and still dominate all heat exchangers. Tubular heat exchangers are mainly composed of shell, tube bundle, tube sheet and head. The shell is mostly circular, with parallel tube bundles inside. Both ends of the tube bundle are fixed on the tube sheet.

In addition, the bolts are prone to rust when used outdoors, further increasing the difficulty of disassembly. Therefore, a tubular heat exchanger that is easy to install and disassemble is proposed to solve the above problems. Utility Model Content
