Description

Technical Field

[0001] This utility model belongs to the technical field of heat exchange equipment, specifically relating to a device that does not directly contact the heat exchange medium, and more particularly to a heat exchanger. Background Technology

[0002] Heat exchangers are widely used in industries such as chemical, semiconductor, and photovoltaic. In the semiconductor cleaning industry, different cleaning processes require different temperatures of the cleaning solution. To meet this requirement, the principle of heat conduction is usually used to transfer heat from one medium to another. Specifically, when the cleaning solution needs to cool a high-temperature hot fluid, the high-temperature hot fluid transfers heat to a low-temperature cold fluid through the pipe wall, and then the heat is discharged from the cold fluid through heat exchange, thus achieving heat transfer. However, directly connecting the heat exchanger to the cleaning solution pipeline can lead to leakage at the pipeline connection and the heat exchanger itself due to the corrosive nature of the solution. To solve this problem, a heat exchanger device has been proposed.

[0003] There is an urgent need to provide a solution to the technical problem of heat exchanger pipe leakage in related technologies.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content
