[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. According to the heat transfer principle, it can be divided into a partition heat exchanger, a heat storage heat exchanger, a fluid-connected indirect heat exchanger, a direct contact heat exchanger, and a compound heat exchanger. Among them, the partition heat exchanger is the most widely used heat exchanger. In the partition heat exchanger, two fluids with different temperatures flow in a space separated by a wall. Heat is exchanged between the two fluids through heat conduction on the wall and convection of the fluid on the wall surface.

[0003] The shell-and-tube heat exchanger is a type of partition-type heat exchanger. When the heat exchanger is in operation, the hot flow medium directly enters each tube bundle from the liquid inlet and flows out from the liquid outlet after completing the heat exchange. When the hot flow medium enters each tube bundle in the heat exchanger, due to the diversion and transportation method, the total contact area of ​​the heat exchange (that is, the total wall area for heat conduction between the hot flow medium and the cold flow medium) is large, so the amount of cold flow medium that absorbs heat and vaporizes into gas is also large. In the process of filling the cavity of the entire heat exchanger shell, the pressure in the shell cavity is changed, which in turn affects the strength of the shell to a certain extent. It is also inconvenient to move and adjust.
