Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger accessories, in particular to a heat exchanger fin with a protection structure. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. Fins are an important component of plate-fin heat exchangers. Through different structural designs, the flowing medium can be made to generate turbulence to improve the heat transfer efficiency of the heat exchanger. In the process of using existing heat exchanger fins, they are prone to damage and deformation, which in turn affects the normal use and normal heat dissipation of the heat exchanger and affects the heat dissipation efficiency of the heat exchanger.

[0003] After retrieval, a Chinese patent with the publication number CN220366737U discloses a heat exchanger fin with a protection structure, including a number of fin bodies. The number of the fin bodies is installed in a protection frame. A buffer is provided between the protection frame and the fin body, and the buffer is also provided between every two of the fin bodies. Two fixing plates are installed on both sides of the protection frame. A number of support plates are welded on one side of each of the two fixing plates. Both sides of the number of fin bodies are clamped between two adjacent support plates.

[0004] Through the setting of the protection frame, the four sides of the fin body can be protected. Through the setting of the buffer, the fin body can be buffered and supported, reducing the deformation of the fin body and increasing the service life of the fin body. Through the setting of the fixing plate, both sides of the fin body can be fixedly supported. Through the setting of a number of support plates, the fin body can be protected, avoiding the phenomenon of deformation and damage of the fin body due to the influence of external forces.

[0005] However, the device still has the following problems. The device is provided with a protection frame. A number of pairs of support plates are fixedly connected to both inner walls of the protection frame. Then, the fin body is fixed between the protection frame and the support plates by a clamping method. In the actual use process, due to the limitation of the support plates and the protection frame, the heat dissipation area of the fin body is inevitably reduced. At the same time, the setting of the protection frame inevitably affects the air flow velocity flowing near the fin body, making it difficult to effectively improve the heat dissipation efficiency of the heat exchange fins.
