Description

Continuous wave-shaped finned tube of air cooler

Technical Field

The utility model relates to an air cooler field, concretely relates to continuous wave air cooler finned tube.

Background

The air cooler is a high-efficiency energy-saving air cooling device and is widely applied to the field of petrochemical industry. A large number of plug-type air coolers are adopted in the existing petrochemical device, and the existing plug-type air cooler pipe box structure comprises an inlet pipe, a top plate, a plug plate, a pipe plate, a heat exchange pipe and other parts. The air cooler mainly adopts a large amount of flowing air to cool the flowing working fluid in the heat exchange pipe, and the working fluid in the production procedure is introduced into the heat exchange pipe through the liquid inlet pipe to be subjected to heat exchange and cooling and then is introduced into the next procedure through the liquid discharge pipe to be processed; the unreasonable heat exchange effect that leads to because of the structural design of heat exchange tube is poor, leads to the working solution temperature after the heat exchange tube cooling to be on the high side to the quality of product has been influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to above problem, make research improvement, provide a continuous wave air cooler finned tube.

In order to achieve the purpose, the utility model provides a continuous wave-shaped finned tube of an air cooler, which comprises a tube body, wherein the tube body is a continuous wave-shaped round tube, a group of uniformly distributed disk-shaped fins are arranged between tube orifices on two sides of the tube body, and the fins are inclined to the same side at the same angle; the pipe orifice is provided with a lining pipe, the outer side of the lining pipe is fixedly connected with an air cooler pipe box, and an elastic body is arranged in a gap between the inner side of the lining pipe and the pipe body.

As a preferred arrangement of the present invention, the fin inclination angle is 60 °.

As the preferred arrangement of the present invention, the elastic body is connected to the pipe body and the bushing pipe in a corrugated shape.

As the utility model discloses an optimal setting, the elastomer material is high temperature resistant rubber materials.

As the utility model discloses an optimal setting, the body the fin material is the stainless steel.

The utility model has the advantages that:

the continuous wavy pipeline structure increases the flow stroke of fluid in the pipeline, and simultaneously the continuous wavy pipeline can change the motion direction and the motion speed of the fluid at each bent part, thereby greatly prolonging the heat exchange time and enhancing the heat exchange effect; a set of a plurality of fins has prolonged the circulation route that the air passes through the heat exchange tube outer wall, further improves its heat transfer effect.

And an elastic body is arranged in a gap between the lining sleeve and the pipe body, the lining sleeve is fixedly connected with the air cooler pipe box, the gap between the finned pipe and the pipe box is eliminated, the finned pipe is limited in the radial direction, the vibration of the finned pipe during working is reduced, meanwhile, the finned pipe can be effectively protected by the rubber elastic body, the abrasion of the finned pipe caused by the impact between the vibration and the pipe box is reduced, and the elastic body can also compensate the abrasion loss by depending on the elasticity of the elastic body even if the abrasion occurs.
