Abstract

The utility model discloses a novel fin, include, the fin strip is a plurality of, and is a plurality of the fin strip distributes in a staggered way mutually, be provided with two at least toothings on the fin strip, through punching press or roll forming toothings. The included angle of both sides of tine is 30-32, the width of the top surface and the bottom surface of tine is the same, the last plane of tine all is in a plane, the lower plane of tine all is in a plane. The fin strip is strip-shaped, the thickness of the fin strip is 0.3mm, and the width of the fin strip is at least 1 mm. The utility model discloses a mechanical punching press or rolled fin can be put in heat exchanger's high temperature side or low temperature side when using, and the rack arrangement of staggering is favorable to when the fin is flowed through to the fluid, and is more smooth and easy, more even inside through whole lumen, when reducing the fluid and passing through the resistance, ensures the passability of the interior little impurity of fluid.

Description

Novel fin

Technical Field

The utility model relates to a heat transfer component technical field specifically is a novel fin.

Background

The finned tube is a heat exchange element. In order to improve the heat exchange efficiency, the contact area (or the inner expanded surface area) between the inner cavity of the heat exchange tube and fluid is increased by adding fins, so that the purpose of improving the heat exchange efficiency is achieved.

The finned tube is used as a heat exchange element and is directly contacted with fluid, so that the finned tube has very direct effects on the turbulence and flow resistance of the fluid and further directly influences the heat exchange performance of the whole heat exchanger. The prior art has poor effect on uniform distribution and flow resistance of fluid after the fins are combined with the tubes.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel fin to solve the relatively poor problem of evenly distributed and the flow resistance effect of the prior art fin that proposes in the above-mentioned background art after combining with the pipe to the fluid.

In order to achieve the above object, the utility model provides a following technical scheme: the novel fin comprises a plurality of fin strips, wherein the fin strips are distributed in a mutually staggered mode, at least two tooth sheets are arranged on the fin strips, and the tooth sheets are formed through stamping or rolling.

Preferably, the included angle of two sides of each tooth sheet is 30-32 degrees, the width of the top surface and the width of the bottom surface of each tooth sheet are the same, the upper planes of the tooth sheets are on the same plane, and the lower planes of the tooth sheets are on the same plane.

Preferably, the fin strip is strip-shaped, the thickness of the fin strip is 0.3mm, and the width of the fin strip is at least 1 mm.

Preferably, the offset distance of the fin strips is half of the distance of the top surfaces of the tooth sheets.

Preferably, the radian of two sides of the top surface of the tooth piece is R0.9mm-1mm, the radian of the lower end of the tooth piece is R0.9mm-1mm, and the distance between the top surface and the bottom surface of the tooth piece is 3.19-3.25 mm.

Preferably, the distance between two adjacent fin strips is 0.3mm-1 mm.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses a mechanical punching press or rolled fin can be put in heat exchanger's high temperature side or low temperature side when using, and the rack arrangement of staggering is favorable to when the fin is flowed through to the fluid, and is more smooth and easy, more even inside through whole lumen, when reducing the fluid and passing through the resistance, ensures the passability of the interior little impurity of fluid.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides a novel fin, includes, fin strip 1 is a plurality of, and is a plurality of fin strip 1 crisscross distribution each other, be provided with two at least tooth pieces 2 on the fin strip 1, fin strip 1 is through punching press or roll forming tooth piece 2.

Furthermore, the included angle of two sides of the tooth piece 2 is 30-32 degrees, the width of the top surface and the width of the bottom surface of the tooth piece 2 are the same, the upper plane of the tooth piece 2 is on one plane, and the lower plane of the tooth piece 2 is on one plane.

Further, the fin strip 1 is strip-shaped, the thickness of the fin strip 1 is 0.3mm, and the width of the fin strip 1 is at least 1 mm.

Further, the offset distance of the fin strip 1 is half of the distance of the top surface of the tooth piece 2.

Furthermore, the radian of two sides of the top surface of the tooth piece 2 is R0.9mm-1mm, the radian of the lower end of the tooth piece 2 is R0.9mm-1mm, and the distance between the top surface and the bottom surface of the tooth piece 2 is 3.22 mm.

Further, the distance between two adjacent fin strips 1 is 0.3mm-1 mm.

The working principle is as follows: the utility model discloses a mechanical punching press or rolled fin are favorable to when the fin is flowed through to the fluid when using, and are more smooth and easy, more even inside through whole lumen, when reducing the fluid and passing through the resistance, ensure the passability of the interior little impurity of fluid.
