Description

Technical Field

[0001] The utility model relates to the technical field of heat exchanger fins, in particular to a heat exchanger fin which is easy to install. Background Art

[0002] Finned heat exchanger is the most widely used heat exchange equipment in gas and liquid heat exchangers. It achieves the purpose of enhancing heat transfer by adding fins to ordinary base tubes.

[0003] In order to ensure that the heat inside the base tube can be easily transferred to the fins and exchange heat with the outside air through the fins, the fins currently used in heat exchangers are generally fixedly connected to the base tube by welding or other methods.

[0004] However, although the fins installed by welding can achieve the heat exchange effect, since the fins are fixedly connected to the base tube, when there is a lot of dust and other debris stuck between the fins during subsequent use, it is difficult for personnel to easily remove the fins for cleaning. In addition, when the fins are tilted and damaged due to being touched by outsiders or objects, it is difficult for personnel to easily remove the fins for cleaning. Therefore, in order to solve the above technical problems, we propose a heat exchanger fin structure that is easy to install. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in order to overcome the above problems, a heat exchanger fin which is easy to install is provided, which solves the above problems.

[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0007] A heat exchanger fin that is easy to install includes a heat exchange tube and two split fin outer tubes. Flange joints are provided at the ends of the fin outer tubes. The flange joints are fixedly connected by bolts. External fins are fixedly welded at intervals on the outer side walls of the fin outer tubes for heat dissipation.

[0008] Preferably, an internal support rib is welded and fixed on the inner wall of the fin outer tube, and the inner circle of the internal support rib abuts against the outer wall of the heat exchange tube to provide good support for the fin outer tube.

[0009] Preferably, a one-way valve injection port is provided on the fin outer tube for filling silicone grease. After the fin outer tube is symmetrically installed, the silicone grease is filled into the gap between the heat exchange tube and the fin outer tube through the one-way valve injection port to ensure the heat exchange efficiency.

[0010] Preferably, sealing rings are fixedly provided on the side wall surfaces of the two fin outer tubes that are in contact with each other.

[0011] Preferably, the built-in supporting ribs are of a hollow structure, so as to facilitate the silicone grease to quickly fill the outer tube of the fin.

[0012] Preferably, the built-in supporting ribs are made of copper-aluminum alloy with galvanized outer wall surface.

[0013] The advantages and positive effects of the utility model are: easy installation, and convenient disassembly, maintenance and cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
