Description

Technical Field

[0001] The utility model belongs to the technical field of heat exchangers, and in particular relates to a heat exchanger with a quick-disassembly structure. Background Art

[0002] A heat exchanger is a device used to transfer heat between two or more fluids. It is widely used in industries such as industry, construction, refrigeration, HVAC, etc. Heat exchangers can be divided into many types according to different working principles and structures. During use, the heat exchanger needs to import the heat source from the outside world and relatively isolate it from the cold source to prevent contact and mixing between different media, which affects the relative purity of the heated medium. During the use of the heat exchanger, the pipes and fittings used to transport the heat source medium are relatively easy to damage, so they need to be maintained or replaced regularly. Some heat exchangers have an integrated structure for the pipes and fittings used to transport the heat source medium, which makes it impossible to disassemble or inconvenience to disassemble during subsequent maintenance and repair operations. It may be necessary to violently disassemble and then weld and assemble, which affects the normal maintenance and repair of the heat exchanger, and thus affects the subsequent normal use of the heat exchanger.

[0003] In summary, heat exchangers without a quick-disassembly structure have some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Summary of the Invention
