Abstract
The utility model relates to a heat exchanger fin which comprises a fin body, a radiating structure and a bending part, wherein the radiating structure is arranged on the fin body, the bending part is arranged on the side of the fin body and is formed by bending the edge of the fin body towards the inner side surface or the outer side surface of the fin body. According to the heat exchanger fin, the bending part is formed by bending the edge of the fin body, so that the tensile strength and impact-resistant performance of the edge of the fin can be greatly improved. Furthermore, according to the heat exchanger fin, the thickness of the fin body does not need to be additionally increased, and the material cost can not be greatly improved, welding process of the existing fin can not be changed, only one bending step is added in the production process of the existing fin, and the production technique is simple. The utility model further provides a heat exchanger provided with the heat exchanger fin.
Description
Technical field
The utility model relates to the heat-exchange apparatus field, especially relates to a kind of heat-exchanger fin and has the heat exchanger of this heat-exchanger fin.
Background technology
At present, the overall structure that heat exchanger for vehicle adopts aluminum pipe and fin assembly welding to form in a large number, wherein the fin majority is the wave banding pattern, the effect in heat-exchange system is that heat and air are exchanged.Because heat exchanger majority be external, condition of work is abominable, and the material of fin is as thin as a wafer, the edge of fin in the vehicle use procedure, easily be subject to foreign matter bump, cause damage, and then affect the performance of heat exchanger even make heat exchanger failure.Usually the solution that adopts at present is to improve the raw-material thickness of fin, perhaps uses more high performance raw material instead.But, improve raw-material thickness, the material cost of heat exchanger can be significantly increased, and after welding, the edgewise compression strength of fin can not be significantly improved; And alternative high performance raw material seldom and might need to change soldering processes, therefore is not solution preferably.Therefore, how to develop the heat-exchanger fin that edgewise compression strength is high, manufacturing process is simple, cost is low and become the technical problem that those skilled in the art need to be resolved hurrily.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of heat-exchanger fin is provided, and has solved the existing technical problem of prior art.
For achieving the above object, the utility model has adopted following technical proposal: a kind of heat-exchanger fin, it comprises fin body, radiator structure and bending part, described radiator structure is arranged on the fin body, described bending part is arranged on the side of described fin body, is formed by medial surface or the lateral surface bending to fin body of the edge of described fin body.
In above-mentioned heat-exchanger fin, preferably, described fin body is the wave band-type of configuration that thin slice is bent into.
In above-mentioned heat-exchanger fin, preferably, described radiator structure comprises the protuberance that a plurality of intervals arrange.
In above-mentioned heat-exchanger fin, preferably, described radiator structure has the opposite protuberance of protrusion direction.
In above-mentioned heat-exchanger fin, preferably, described bending part is arranged on two sides of described fin body, is formed by the lateral surface bending to described fin body of the edge of described fin body.
In above-mentioned heat-exchanger fin, preferably, described bending part and described fin body are fitted.
In above-mentioned heat-exchanger fin, preferably, the folding surface between described bending part and the described fin body is circular arc.
In above-mentioned heat-exchanger fin, preferably, described fin body is that aluminium or copper become.
The utility model also provides a kind of heat exchanger, and it comprises above-mentioned each described heat-exchanger fin.
This heat-exchanger fin forms bending part by the edge bending with fin body, can greatly improve compression strength and the impact resistance of fin edges.And this heat-exchanger fin need not to increase fin body thickness, can significantly not increase material cost, also need not to change simultaneously existing fin welding procedure, and only needing increases a bending step in existing fin production technology, so production technology is simple.
Description of drawings
Fig. 1 is the structural representation of the heat-exchanger fin that provides of the utility model.
Fig. 2 is the partial structurtes schematic diagram of the heat-exchanger fin of Fig. 1.
Among the figure, 100, heat-exchanger fin; 10, fin body; 20, radiator structure; 30, bending part.
The specific embodiment
Please refer to Fig. 1 and Fig. 2, the heat-exchanger fin 100 that the utility model embodiment provides comprises fin body 10, radiator structure 20 and bending part 30.
The wave band-type of configuration that fin body 10 is bent into for thin slice.In the present embodiment, fin body 10 is that aluminium or copper become.
Bending part 30 is arranged on the side of fin body 10, is formed by medial surface or the lateral surface bending of fin body 10 edges to fin body 10.In the present embodiment, bending part 30 is arranged on two sides of fin body 10, is formed by the lateral surface bending to fin body 10 of the edge of fin body 10, and bending part 30 is fitted with fin body 10.The width of bending part 30 is 0.5-2.0mm.Preferably, the folding surface between bending part 30 and the fin body 10 is circular arc, is conducive to improve better compression strength and the impact resistance of fin edges.
This heat-exchanger fin 100 forms bending part 30 by the edge bending with fin body 10, can greatly improve compression strength and the impact resistance of fin edges.And this heat-exchanger fin 100 need not to increase fin body thickness, can significantly not increase material cost, also need not to change simultaneously existing fin welding procedure, and only needing increases a bending step in existing fin production technology, so production technology is simple.
The utility model also provides a kind of heat exchanger with above-mentioned heat-exchanger fin, and it also has the various beneficial effects of above-mentioned heat-exchanger fin certainly.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used the terms such as heat-exchanger fin, fin body, radiator structure, bending part, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
