[0002] A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements, and it is an industrial application of convective heat transfer and heat conduction. Heat exchangers can be classified in different ways: according to their operating processes, they can be divided into three categories: shell-and-tube heat exchangers, direct contact heat exchangers, and regenerative heat exchangers (or recuperators); according to the compactness of their surfaces, they can be divided into two categories: compact heat exchangers and non-compact heat exchangers.

[0003] Based on the above, the inventor found the following problems: after the existing heat exchanger is used for a period of time, dirt is likely to adhere to the inside of the pipeline.
