Abstract

The utility model discloses a sheet-through heat sink, which belongs to the field of heat sinks. It includes pipes and heat dissipation fins, the heat dissipation fins are wave-shaped, and through holes are formed in the transverse direction. The pipe passes through the through hole on the heat dissipation fin and is welded and fixed to the heat dissipation fin, and the heat dissipation fin is in the shape of a flat sheet or a windowed fin. The through hole is preferably circular, and the pipe is selected as a circular tube matching the through hole. The heat dissipation fins are made with through holes, and the pipes are welded after passing through the holes, which is more reliable and can adapt to harsh vibration environments without the phenomenon of fin loss.

Description

Wear sheet fin

Technical field

The utility model belongs to fin field, is specifically related to one and wears sheet fin.

Background technology

Exchange field, as automobile water tank radiator, is made up of metallic conduit and metal fin, and the medium being cooled is water, in pipeline, flows.Cooling medium is air, contacts with pipeline outer wall with metal fin, takes away heat.Convection transfer rate between air and metal is very little, and the effect of metal fin is to increase heat exchange area, reduces thermal resistance, strengthens heat transfer effect.Common version is between pipeline and pipeline, to be fin at present, more integrally welded.This version requires pipeline section to be shaped as oblong shape, and the position contacting with fin is plane, and guarantee contacts with fin part is seamless, the shape relative complex of pipeline.Under the condition of work of vibration, between fin and pipeline, easy sealing-off, causes wing, and heat transfer effect declines thereupon, and reliability decreases.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides one to wear sheet fin.

The utility model is to adopt following technical scheme to realize: one is worn sheet fin, and it comprises pipeline and radiating fin.It is characterized in that: described radiating fin is waveform, and be laterally manufactured with through hole; Described pipeline is fixedly connected with radiating fin through the through hole on radiating fin.

Further: described radiating fin is welded on pipeline outer wall.

Described radiating fin is plain film shape or louvered fin shape.

Described through hole is circular, and described pipeline is the round tube matching with through hole.

The beneficial effects of the utility model are: in the utility model, radiating fin is manufactured with through hole, and pipeline welds through behind hole, more firm, can adapt to severe vibration environment, does not fall the phenomenon of wing; Easily manufactured, reliability is high.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is described in further detail.

Fig. 1 is perspective view of the present utility model;

Fig. 2 is the utility model generalized section.

In figure: 1, pipeline, 2, radiating fin.

Detailed description of the invention

As depicted in figs. 1 and 2, one is worn sheet fin, and it comprises pipeline 1 and radiating fin 2; It is characterized in that: described radiating fin 2 is waveform, and is laterally manufactured with through hole; Described pipeline 1 is through the through hole on radiating fin 2, and pipeline 1 outer wall surrounding contacts with radiating fin 2, and is welded and fixed.Described radiating fin 2 is preferentially chosen as plain film shape or louvered fin shape, improves heat transfer efficiency.Through hole circular on described radiating fin 2, the described pipeline 1 selection round tube that matches with through hole.Described pipeline and radiating fin are metal material

As shown in Figure 2, in use, medium one flows along pipeline 1 is interior, with pipeline 1 inwall generation heat exchange, heat is by pipeline 1 and radiating fin 2 perimeter of preaching, medium two flows in pipeline 1 perimeter, with pipeline 1 outer wall and fin 2 surfaces, heat exchange occurs, thereby completes the heat exchanging process of medium one and medium two.
