Problems solved by technology

[0002] When the fins are installed in the heat exchanger, it is used to increase the surface area of ​​the heat exchanger and improve the heat exchange efficiency. The heat exchange efficiency of the fins with a height of 2mm is relatively higher than that of the same type of fins. The performance is better, but there is a large resistance. The gas or liquid that needs temperature adjustment needs to provide a large power when passing through the heat exchanger, and it is easy to trap the dirt in the gas or liquid, further increasing the resistance and causing channel blockage.

Embodiment Construction

[0016] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0017] see Figure 1 to Figure 3 , the low-resistance zigzag fins are welded by several fin bodies 1 with a thickness of 0.15 mm, and several fin bodies 1 are arranged alternately in pairs. Starting from the convex mouth 3 of the fin plate 2, the shape of the convex mouth 3 is a U-shaped convex mouth 3, and 10 U-shaped convex mouths 3 are arranged on the described fin body. The pitch of the opening is 4mm, the depth of the protrusion 3 is 2mm, and the length of the fin body 1 is 30mm.

[0018] The pitch of the convex mouth 3 is reduced, which reduces the resistance of the fin body 1, and the fin body 1 with a large pitch and a small thickness has light weight and is convenient for transportation. In addition, the U-shaped convex mouth 3 can also be modified. With the V-shaped convex notch 3, the d...

Abstract

The invention discloses a low-resistance sawtooth-shaped fin which is formed by splicing a plurality of fin bodies, wherein the fin bodies are staggered two by two; each fin body comprises a fin flat plate and a convex opening protruding from the fin flat plate; opening pitches of the convex openings are 3.5-4.5mm; the convex openings are 2mm in depth, and the fin bodies are 30mm in length; by enlarging the opening pitches of the fin bodies, on the premise of not affecting the heat dissipation effect, the resistance of the fin bodies is reduced, so that pollutes in fluid flowing through the fin are difficultly blocked by the convex openings, and blocking of the fin bodies is prevented.

Description

technical field [0001] The invention relates to heat exchanger equipment, in particular to a serrated fin with low resistance. Background technique [0002] When the fins are installed in the heat exchanger, it is used to increase the surface area of ​​the heat exchanger and improve the heat exchange efficiency. The heat exchange efficiency of the fins with a height of 2mm is relatively higher than that of the same type of fins. The performance is good, but there is a large resistance. The gas or liquid that needs temperature adjustment needs to provide a large power when passing through the heat exchanger, and it is easy to trap the dirt in the gas or liquid, further increasing the resistance and causing channel blockage. Contents of the invention [0003] The object of the present invention is to provide a low-resistance zigzag fin with little resistance. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A ...
