Abstract

The utility model discloses a circular heat exchange fin, including first fin and second fin, first fin and second fin all are the disc, first fin adopts pipeline fixed connection to be in the same place with the second fin, first fin and second fin surface machining have a plurality of archs. The utility model discloses a circular heat exchange fin conveniently tailors processing, and the fin edge is the circular closed angle that does not have, therefore is difficult for hindering the hand, the utility model discloses effectively improve the heat exchange efficiency who installs the heat exchange device of this fin, has practiced thrift the energy, the utility model has the advantages of simple structure, low in manufacturing cost, convenient to use.

Description

A kind of circular heat exchange fin

Technical field

The utility model relates to a kind of parts of technical field of heat exchange, refers to a kind of circular heat exchange fin especially.

Background technology

In technical field of heat exchange, conventional heat exchanging fin has pipe with wound fin, plate finned tubes, empiecement pipe and roll sheet pipe etc., pipe with wound fin is that very thin sheet metal is confined through warding off tin around to light pipe, but root fold place is easily contaminated, remove difficulty, empiecement pipe is that light pipe outer wall is rolled out helicla flute on special purpose machine tool, metal tape is wound around in groove, make it fastening through extruding, but manufacturing process relative complex, and quality can not ensure, thus the raising of heat exchanger effectiveness is limited, and patent " a kind of heat exchange fin of rectangle " (application number: 201110437839.8) adopt rectangle heat exchange fin, both inconvenient cutting processing, also easily hand is hindered.

Utility model content

Problem to be solved in the utility model is the deficiency overcome in background technology, provides a kind of circular heat exchange fin, this circular heat exchange fin, and structure is simple, effectively can improve heat exchanger effectiveness.

For solving the problem, the utility model takes following technical scheme:

The circular heat exchange fin of one of the present utility model, comprise the first fin and the second fin, described first fin and the second fin are all in disc, and described first fin and the second fin adopt pipeline to be fixed together, and described first fin and the second flap surface are processed with multiple projection.

Further, described first fin and the second fin adopt two pipelines to be fixed together.

Further, the two ends of described pipeline respectively seal welding on the surface of the surface of the first fin and the second fin.

Because two pipelines are formed with described first fin and the second fin respectively seal, therefore, exchange heat between two panels fin just completes by close-connected pipeline, sealing structure makes heat exchanger effectiveness greatly improve, the projection of the Surface Machining of described fin, in order to increase the rigidity of fin, and the turbulent flow of fin outer fluid can be strengthened.

The circular heat exchange fin of one of the present utility model, owing to comprising the first fin and the second fin, described first fin and the second fin are all in disc, described first fin and the second fin adopt pipeline to be fixed together, described first fin and the second flap surface are processed with multiple projection, therefore, the circular heat exchange fin of one of the present utility model, conveniently cut out processing, and flap edges is rounded does not have wedge angle, thus not easily hand is hindered, the utility model effectively improves the heat exchanger effectiveness of the heat-exchange device installing this fin, save the energy, it is simple that the utility model has structure, low cost of manufacture, the advantage such as easy to use.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

As shown in Figure 1, a kind of circular heat exchange fin of the utility model, comprise the first fin 1 and the second fin 2, described first fin 1 and the second fin 2 are all in disc, described first fin 1 and the second fin 2 adopt pipeline 3 to be fixed together, and described first fin 1 and the second fin 2 Surface Machining have multiple protruding 4.

Described first fin 1 and the second fin 2 adopt two pipelines 3 to be fixed together.

The two ends of described pipeline 3 respectively seal welding on the surface of the surface of the first fin 1 and the second fin 2.

Because two pipelines 3 are formed with described first fin 1 and the second fin 2 respectively seal, therefore, exchange heat between two panels fin just completes by close-connected pipeline 3, sealing structure makes heat exchanger effectiveness greatly improve, 6 projections 4 of the Surface Machining of described fin, in order to increase the rigidity of fin, and the turbulent flow of fin outer fluid can be strengthened.The circular heat exchange fin of one of the present utility model, conveniently cut out processing, and flap edges is rounded does not have wedge angle, thus not easily hand is hindered, the utility model effectively improves the heat exchanger effectiveness of the heat-exchange device installing this fin, saved the energy, it is simple that the utility model has structure, low cost of manufacture, the advantage such as easy to use.

Should be noted that; the foregoing is only preferred embodiment of the present utility model, be not limited to the present embodiment, all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
