Description

A kind of radiator fin

Technical field

The utility model relates to the concrete structure of a kind of radiator fin.

Background technology

Traditional mining lamp all adopts stretching Section Bar Heat Sinks, and it is low that stretching section bar has die cost, and lamp power changes the features such as flexible, and still, along with the increase of lamp power, the cost of light fixture is more and more higher, and the weight of light fixture is also more and more heavier. In the time of the high-power high-performance bulkhead lamp capable of exploitation, stretching Section Bar Heat Sinks has just demonstrated its weak point, and due to light fixture enlarged diameter, die cost also will increase, and lamp power strengthens, and length and the weight of light fixture increase simultaneously.

The integrated formed structures that adopt between the fin of traditional heat-dissipating device and base plate more, complex process, production cost is high, and dismounting, keep in repair very inconvenient. In addition, between traditional heat-dissipating device fin and fin, easily pile up dust, directly affect the radiating efficiency of radiator.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of plug-in type radiator fin is provided, and dismounting, easy to maintenance prevents dust accretions under the prerequisite that ensures radiating efficiency.

The purpose of this utility model is achieved through the following technical solutions: a kind of radiator fin, comprise fin body, the top of fin body is provided with radiating part, between radiating part and fin body, be provided with bayonet socket, the top of fin body is also provided with the first back-up block, matches with the position of bayonet socket in the position of the first back-up block; The bottom of fin body is provided with at least one projection of pegging graft, and the bottom of fin body is also provided with the second back-up block, and the second back-up block flushes with the protruding end of pegging graft.

The first described back-up block and the second back-up block are all vertical with fin body place plane.

The arranged outside of described fin body has dust excluding plate, and dust excluding plate is vertical with fin body place plane.

On described dust excluding plate, be provided with at least one louvre.

The beneficial effects of the utility model are:

1) adopt connected structure to be connected with base plate and fixed head, dismounting, maintenance and convenient transportation.

2) the first back-up block and the second back-up block can support fin well, make fin more firm with being connected of base plate and fixed head.

3) dust excluding plate can prevent that airborne dust is attached in fin gap well, thereby ensures the good heat conduction efficiency of fin.

4) on dust excluding plate, be provided with multiple louvres, further ensured the radiating efficiency of radiator.

In figure, 1-fin body, 2-radiating part, 3-bayonet socket, 4-the first back-up block, 5-pegs graft protruding, 6-the second back-up block, 7-dust excluding plate, 8-louvre.

Detailed description of the invention

Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.

As shown in Figure 1, a kind of radiator fin, comprise fin body 1, fin body 1 is square, and the top of fin body 1 is provided with radiating part 2, radiating part 2 is triangular in shape, between radiating part 2 and fin body 1, be provided with bayonet socket 3, bayonet socket 3 matches with the fixed head of radiator, concrete, the width of bayonet socket 3 matches with the thickness of fixed head, so that the engaging better effects if of pegging graft. The top of fin body 1 is also provided with the position of the first back-up block 4, the first back-up blocks 4 and matches with the position of bayonet socket 3, and the fixing board card of radiator is connected on bayonet socket 3 when interior, and the first back-up block 4 is adjacent to fixed head. The bottom of fin body 1 is provided with at least one projection 5 of pegging graft, and the projection 5 of pegging graft matches with the slot on base plate of radiator. The bottom of fin body 1 is also provided with the second back-up block 6, the second back-up blocks 6 and flushes with the end of the projection 5 of pegging graft, and on the projection of pegging graft 5 slots that are plugged on base plate of radiator time, the second back-up block 6 is adjacent to base plate.

As preferably, the first described back-up block 4 and the second back-up block 6 are all vertical with fin body 1 place plane.

In the present embodiment, the arranged outside of described fin body 1 has dust excluding plate 7, and dust excluding plate 7 is vertical with fin body 1 place plane.

Further, on described dust excluding plate 7, be provided with at least one louvre 8.

The above is only preferred embodiment of the present utility model, be to be understood that the utility model is not limited to disclosed form herein, should not regard the eliminating to other embodiment as, and can be used for various other combinations, amendment and environment, and can, in contemplated scope described herein, change by technology or the knowledge of above-mentioned instruction or association area. And the change that those skilled in the art carry out and variation do not depart from spirit and scope of the present utility model, all should be in the protection domain of the utility model claims.
