Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a sealing strip for heat exchangers. Background Technology

[0002] Plate-fin heat exchangers utilize the disturbance of fluids by fins to continuously break the boundary layer, thus achieving a large heat transfer coefficient. Simultaneously, the high thermal conductivity of the metal materials used in manufacturing plate-fin heat exchangers enables them to achieve excellent heat transfer efficiency. A plate-fin heat exchanger mainly consists of a core and end caps. The core primarily comprises seals, baffles, and fins. The seals, as a crucial component, seal the heat and cold medium passages and provide structural support for the fins.

[0003] Existing sealing strips have some shortcomings in use, such as low structural strength and poor resistance to deformation, which affect the sealing effect and have a short service life. Therefore, we propose a new type of sealing strip for heat exchangers. Utility Model Content
