Description

Technical Field

[0001] The utility model relates to the technical field of spoiler bars, in particular to a spoiler bar for enhancing heat transfer. Background Art

[0002] A turbulator (also known as a spoiler bar or turbulence enhancer) is a device that enhances turbulence by changing the fluid flow state and disrupting the laminar boundary layer. Its core function is to improve the mixing efficiency between the fluid and the heat transfer surface or different fluids, and it is widely used in heat exchangers, chemical mixing equipment, fluid输送 pipelines and other fields.

[0003] In industrial processes such as fluid输送, heat exchange, and mixing, it is often necessary to increase the turbulence degree of the fluid through a spoiler bar (turbulator) to improve efficiency. However, the existing spoiler bars have the problems of cumbersome installation and limited spoiler effect. Some spoiler bars require professional tools for installation and are difficult to quickly adapt to different devices. At the same time, their structural design has not been fully optimized, resulting in insufficient disturbance of the fluid and affecting the heat exchange or mixing effect. Therefore, we urgently need an improved spoiler bar to solve the above problems. Summary of the Utility Model

[0004] In view of the deficiencies of the existing technology, the utility model provides the following technical solutions:

[0005] A spoiler bar for enhancing heat transfer, comprising a fixing part and a spoiler part;

[0006] The fixing part is arranged at one end of the spoiler part;

[0007] The fixing part includes a stamping sheet and a first metal strip, and the fixing part is formed by pressing the stamping sheet and the first metal strip, and a plurality of reinforcing members are welded and fixed between the stamping sheet and the first metal strip;

[0008] The spoiler part includes a second metal strip and metal wires. The metal wires are arranged outside the second metal strip. The second metal strips are staggered with each other in a spiral shape. The metal wires are distributed in a bent spiral shape and staggered on the second metal strip. The second metal strip and the metal wires are fixed by welding.

[0009] As an improvement of the above technical solution, the reinforcing member is in a "U" shape, and the reinforcing member is a stainless steel metal component.

[0010] As an improvement of the above technical solution, the second metal strip in the spoiler part and the first metal strip in the fixing part are integrally formed.

[0011] As an improvement of the above technical solution, the fixing part and the first metal strip are pressed by a machine to form a clamping structure. The opening angle of the clamping structure is 30° - 60°, and the first metal strip is an elastic metal strip component.

[0012] As an improvement to the above technical solution, the metal wire of the turbulence section is made of stainless steel and its surface is polished.

[0013] As an improvement to the above technical solution, the fixing part and the turbulence-disrupting part are connected by welding, and the fixing part is located at the top of the turbulence-disrupting part.

[0014] As an improvement to the above technical solution, the spiral and zigzag shapes of the turbulence-inducing parts are staggered along the fluid direction to form a multi-level turbulence-inducing structure.

[0015] The beneficial effects of this utility model are:

[0016] 1. The metal strips and wires in the turbulence section are arranged in a bent and complex spiral pattern and are processed by special technology. Based on the principles of fluid mechanics, they can greatly increase the fluid contact area, force the fluid to change its flow direction and form a large number of small eddies, and significantly enhance the degree of turbulence. In heat exchange scenarios, they can make the fluid contact the heat exchange surface more fully and improve the heat exchange efficiency; in mixing scenarios, they can accelerate the mixing of different fluids.

[0017] 2. By using a clamping structure formed between a stamped sheet and a metal strip in the fixing part, the turbulence device can be successfully installed and fixed to the surface of the equipment, such as the pipe or container wall, by hand, which greatly saves installation time and labor costs, significantly improves installation efficiency, and thus increases the convenience of installation.
