Abstract

The utility model discloses an air-cooling fin of a plate-fin type radiator, comprising a plurality of fins and composite plates fixedly connected with fins; two adjacent fines are spaced with the composite plates; a side face of each fine is like a wave; the top of each fin is flat; the side face of each fin is provided with at least two bending units formed end-to-end. Each bending unit has an included angle of 15-75 degrees centigrade. The air-cooling fin provided by the utility model has the advantages that heat exchange efficiency is significantly improved, and the air-cooling fin is easily produced.

Description

A kind of wind-cooling heat dissipating sheet of plate fin type radiator

Technical field

The utility model relates to the heat exchange equipment field, particularly relates to the fin of heat exchanger.

Background technology

Heat exchanger has been widely used in fields such as aviation, automobile, diesel locomotive, engineering machinery, air compression, air separation, petrochemical industry, air-conditioning, refrigeration at present.Wherein aluminum plate-fin heat exchanger at first obtains strong propelling in empty branch trade, and is as shown in Figure 1, and fin is the significant element that constitutes plate-fin heat exchanger, and heat exchanger is being brought in constant renewal in fin structure.Fin has two effects generally in heat exchanger structure: 1, supporting-core body structure 2, participate in the exchange of heat as the secondary heat exchange face.The fin type of practical application at present has a lot, like flat type, zigzag, ripple type, undaform or the like.Satisfying under the required intensity prerequisite of support, what need consideration emphatically is exactly how on fin structure, to make improvement, to increase heat.Increase heat and mainly contain two technique directions, promptly how to increase heat exchange area and how to strengthen turbulent flow.Fin in use if working environment is more abominable, takes place and stops up in rippled fin easily, influences properties of product, need improve to boost productivity prior art.

The utility model content

The utility model has been to overcome the defective of prior art, and the wind-cooling heat dissipating sheet of the plate fin type radiator that a kind of production efficiency is high, failure free time is long is provided.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

Comprise that a plurality of fins reach and the affixed composite plate of fin, two adjacent said fin and composite plate spaces, said fin side is similar to undulate, and said fin top is a flat, in said fin side, comprises the bend unit that two tandem arrays are processed at least.

Said bend unit is 15 °-75 ° of angles.

Compared with prior art, the utlity model has following beneficial effect:

Strengthen properties of product, and can enhance productivity.

To the not high shortcoming of former money radiating efficiency, change the fin side into the setback face, make the fluid flow direction that gets into fin constantly change, air-flow produces disturbance, thereby has aggravated turbulent flow, has improved heat exchange efficiency.

Change fin top into flat shape, the rolling of band machine is rolled in the fin utilization at a high speed, has realized high speed machine production, thereby has improved production efficiency greatly.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Shown in Fig. 2-6, the wind-cooling heat dissipating sheet of plate fin type radiator comprises that a plurality of fins 1 reach and affixed composite plate 2, two adjacent fins 1 and composite plate 2 spaces of fin; Fin 1 lateral surface is similar to undulate, and fin top is a flat, in said fin side; The bend unit 3 that a plurality of tandem arrays are processed, bend unit 3 are 15 °-75 ° of angles, make the fluid flow direction that gets into fin 1 constantly change; Air-flow produces disturbance, thereby has aggravated turbulent flow, has improved heat exchange efficiency.

The utility model mainly is to be used for aluminum plate-fin heat exchanger; Change the fin side into the setback face in the fin cut-away portions; Form the concaveconvex shape of arranging according to certain rules, increase this concaveconvex shape is to prevent to occur in the product use fin to stop up as far as possible, and this kind fin can utilize high speed to roll the rolling of band machine; Realized high speed machine production, enhanced productivity.

The above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.

Claims

1. the wind-cooling heat dissipating sheet of a plate fin type radiator; Comprise that a plurality of fins reach and the affixed composite plate of fin, is characterized in that two adjacent said fin and composite plate spaces; Said fin side is similar to undulate; Said fin top is a flat, in said fin side, comprises the bend unit that two tandem arrays are processed at least.

2. the wind-cooling heat dissipating sheet of plate fin type radiator according to claim 1, it is characterized in that: said bend unit is 15 °-75 ° of angles.
