Abstract

The utility model discloses a heat dissipation device provided with pins comprising a long strip-shaped main body made of aluminum alloy materials. The upper surface of the main body is provided with a plurality of parallel fins along a longitudinal direction. The upper surface of the main body is also provided with a groove, in which is disposed a screw hole penetrating the upper surface and the lower surface of the main body. A heat conduction silicon sheet is disposed in the groove, and two sides of the main body are provided with bending sheets, which are parallel to the fins, and are provided with pins. The bending sheets and the fins are disposed on the same surface of the main body. The heat dissipation device is advantageous in that the main body is provided with a plurality of fins, and therefore the heat dissipation area is greatly increased, and the cross ventilation can be enhanced, and then the heat dissipation problem of the electronic elements having high heating value in the limited space can be solved; the main body is provided with the pins, and therefore the heat dissipation device and the bottom plate can be fixedly connected together in various ways.

Description

A kind of radiator with pin

Technical field

The utility model relates to a kind of radiator, relates to specifically a kind of radiator with pin.

Background technology

On circuit board, be generally welded with multiple electronic devices and components, wherein, some electronic devices and components are elements that caloric value is high, and the heat when by the work of high these caloric values element distributes as early as possible, configure separately radiator generally can to the high electronic devices and components of these caloric values.Expanding area of dissipation is the effective way in various heat transfer types, conventional method is by increasing radiator shutter, area of dissipation to be increased, but easily cause the volume and weight of radiator to increase, and then the application of this method is restricted, meanwhile, radiator shutter only has a side and base plate to fix conventionally, long-term use can make radiator shutter unstable, therefore,, based on the defect of above-mentioned existing radiator, need to improve existing radiator.

Utility model content

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of radiator with pin, this radiator has that area of dissipation is large, the good advantage of radiating effect, can in limited space, solve the heat dissipation problem of the electronic devices and components that caloric value is high preferably.

To achieve these goals, the technical solution adopted in the utility model is: a kind of radiator with pin, comprise main body, described main body is strip and is made up of aluminum alloy materials, suitable long to being provided with multiple fins that are parallel to each other on main body, suitable long to being also provided with groove on main body, in groove, be provided with screw hole, screw hole runs through the top and bottom of main body, in groove, be also provided with heat-conducting silica gel sheet, be provided with bent sheet in the both sides of main body, its bent sheet is parallel with fin, all be positioned at the same face of main body, in bent sheet, be provided with pin.

Preferably, the material one-shot forming that described fin and main body are identical material is made.

Further, the two sides of described fin is also provided with protruding ripple glaze.

Further, the end of described bent sheet is not higher than the top of fin.

Adopt the utility model of the technical program, its beneficial effect is: radiator of the present utility model, due to the multiple fins of being provided with of main body, this just makes area of dissipation greatly increase, and can effectively strengthen cross-ventilation, thereby in space that can be limited, solve preferably the heat dissipation problem of the electronic devices and components that caloric value is high.In addition,, due to the pin that is provided with of main body, make fixed form and approach between radiator and base plate there are multiple choices.Heat spreader structures of the present utility model is simple, good heat dissipation effect, and fixed form is many.

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

Number in the figure: 1, main body; 2, fin; 3, heat-conducting silica gel sheet; 11, groove; 12, screw hole; 13, bent sheet; 14, pin; 21, ripple glaze.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1, radiator with pin of the present utility model, comprise main body 1, described main body 1 is strip and is made up of aluminum alloy materials, suitable long to being provided with multiple fins that are parallel to each other 2 on main body 1, suitable long to being also provided with groove 11 on main body 1, in groove 11, be provided with screw hole 12, screw hole 12 runs through the top and bottom of main body 1, in groove 11, be also provided with heat-conducting silica gel sheet 3, be provided with bent sheet 13 in the both sides of main body 1, its bent sheet 13 is parallel with fin 2, all be positioned at the same face of main body 1, in bent sheet 13, be provided with pin 14.Described fin 2 is made with the material one-shot forming that main body 1 is identical material.The two sides of described fin 2 is also provided with protruding ripple glaze 21.The end of described bent sheet 13 is not higher than the top of fin 2.

In use, the screw hole 12 in main body 1 can be used for fixedly mounting radiator, also can work as the cable-through hole of electronic component down-lead and use.In addition, the height wide dark and fin 2 of its groove 11 all can be determined according to actual demand, does not specifically just repeat at this.

Above are only a kind of embodiment of the present utility model; not in order to limit the utility model; those skilled in the art can make various changes and improve said structure; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
