The utility model has the advantages of simple structure, easy manufacture, low cost, good heat emission effect and the like, which may be used as the heat emission device of a plurality of large electric appliances.

Description

Novel corrugated plate formula finned radiator

Technical field:

The utility model relates to a kind of radiator, relates in particular to a kind of finned radiator.

Background technology:

At present, the finned radiator that is used for electronic equipment mostly is the blade inserting structure, promptly processes some fin mounting grooves on radiator base plate, and the fin of slab construction inserts in this groove, by modes such as mechanical presses or welding fin is fixed then.Mainly there are defectives such as process structure complexity, processing trouble, cost height and poor rigidity, area of dissipation are little in the radiator of this traditional structure.

The utility model content: at the above-mentioned defective that exists in the prior art, the utility model aims to provide that a kind of structural rigidity is good, easy to process, the novel corrugated plate formula finned radiator of good heat dissipation effect.

To achieve these goals, the utility model by the following technical solutions: it comprises substrate, is fixed on the some fins on this substrate; The stage casing that cross sectional shape is the fin of I-shaped structure is corrugated curved slab; Each fin is connected as a single entity by the positioning step combination overlap joint that is located at upper and lower end respectively and is fixed on the substrate.

The middle section surface of fin is provided with laciniation.

Compared with the prior art, the utility model is owing to adopted technique scheme, therefore can utilize anchor clamps and the mode by soldering that each fin is assembled fast and form the radiator that is fixed on substrate, thereby simplify processing technology effectively, improved production efficiency; Because the top of each fin overlaps mutually and is connected as a single entity, therefore improved the rigidity of radiator greatly, the top that has thoroughly overcome the traditional heat-dissipating device is easily because of the defective of pushing or collision deforms; In addition,, therefore increased the area of dissipation of fin effectively, can improve radiating efficiency about 7% because the stage casing of fin is wavy curved slab.

Description of drawings:

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

Fig. 2 is the enlarged drawing among Fig. 1;

Fig. 3 is the structural representation of traditional finned radiator.

Among the figure: fin 1 solder plate 2 substrates 3

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In Fig. 1～2, the cross sectional shape of fin 1 is I-shaped structure, and the stage casing of this fin is corrugated curved slab, is provided with positioning step in the top and bottom of fin 1; Be linked to be a radiator that is fixed on the substrate 3 by described positioning step combination overlap joint between each fin 1.For the area of dissipation that further increases fin 1, improve radiating effect, be provided with laciniation at the middle section surface of fin 1.

For the ease of making, scribble the solder of welding usefulness at the positioning step place of each fin 1, utilize anchor clamps that each fin 1 assembly is got up to form a radiator then, again this radiator is positioned on the substrate 3 by the solder plate 2 that scribbles solder, entire radiator is sent in the soldering oven welded at last.

Be not difficult to find out that from Fig. 3 the fin 1 of traditional heat-dissipating device directly is inserted in the mounting groove of substrate 3 and by the mode of extruding or welding and fixes; Because the locus between each fin 1 is narrower, therefore operation is relatively more difficult when pushing or welding fixedly, and productivity ratio is lower; In addition, because each fin 1 is for plate-like structure and upper end are separated from each other, so the radiating effect of radiator is bad, and rigidity is also relatively poor, easy deformation.
