[0002] Shell and tube heat exchanger is also called shell and tube heat exchanger. It is a wall heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. This type of heat exchanger has a simple structure, low cost, wide flow cross section, and is easy to clean scale, but has a low heat transfer coefficient and occupies a large area. It can be made of various structural materials (mainly metal materials) and can be used under high temperature and high pressure. It is the most widely used type.
[0003] The existing shell and tube heat exchanger device has the problem of not being able to descale the inner wall of the fluid port during use, resulting in scaling on the inner wall of the fluid port, which accumulates over time, thereby affecting the heat exchange efficiency of the heat exchanger, reducing the heat exchange efficiency of the heat exchanger. Secondly, the existing shell and tube heat exchanger device has the problem of being difficult to clean during use, because the space between the tube bundle and the shell is narrow, which makes it inconvenient to clean the inside of the heat exchanger.

[0021] In the above structure, by setting the handle 17, when there is no need to clean the inner wall of the heat exchanger body 1, the handle 17 is used to pull the round block 14 upward to separate the round block 14 from the inner wall of the fluid port 2 3, so that the fluid port 2 3 can work normally.
[0022] In a preferred embodiment, a water pump is disposed on the inner wall of the water tank 16 , and a water inlet is disposed on the top of the water tank 16 .
[0023] In the above structure, by setting the water inlet, water can be injected into the inner wall of the water tank 16, so that the round block 14 and the second limit block 15 can clean the inner wall of the heat exchanger body 1.

[0025] In the above structure, the second limiting block 15 is slidably connected with the second limiting groove, so that the second limiting groove can be used to limit the round block 14.
[0026] In a preferred embodiment, a support 5, a fluid port three 6 and a fluid port four 7 are fixedly mounted on the outer edge of the heat exchanger body 1, and the number of the supports 5 is two.
[0027] In the above structure, the stability of the device is improved by providing two supports 5 .
