Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically a heat exchanger with a fixed anti-fall-off function. Background Technology

[0002] Heat exchangers are key devices for transferring heat from one medium to another, and are widely used in chemical, energy, refrigeration, and other fields. In the actual use of heat exchangers, installation stability is a crucial prerequisite for ensuring their efficient and safe operation.

[0003] Existing heat exchangers still have the following problems in use: On the one hand, the connection between traditional heat exchangers and external installation structures is relatively simple. During long-term operation or when affected by vibration, the connection is prone to loosening or even falling off, which seriously affects the continuity and safety of heat exchange. On the other hand, the heat exchange structure design of some heat exchangers is relatively simple, and the heat transfer efficiency needs to be further improved, making it difficult to meet the heat exchange requirements under high load conditions. In addition, most existing heat exchangers lack convenient operating status observation structures, making it inconvenient for operators to keep abreast of the internal medium flow and heat exchange status, which brings inconvenience to the maintenance and management of the equipment.
