Abstract

The utility model relates to an aluminium extruded radiating fin capable of increasing the radiating efficiency, which is composed of a radiating fin and a heat conducting fin, wherein the bottom of the radiating fin is provided with at least one calking groove which can be matched with the heat conducting fin made of materials with better heat conductivity (such as copper, etc.). The bottom surface of the heat conducting fin is directly contacted with an electronic assembly so that heat can be conducted to the radiating fin by the heat conducting fin to be radiated to the air, and accordingly, the utility model can achieve a favorable radiating effect.

Description

Has the aluminium extruded type fin that increases radiating efficiency

The utility model relates to a kind of aluminium extruded type fin that increases radiating efficiency that has, refer in particular to a kind of being installed on the electronic building brick, its material that thermal conductivity is preferable is located at the bottom of fin, and can be by its capacity of heat transmission to improve the aluminium extruded type fin of radiating efficiency.

Because the quick upgrading of computer industry, to develop the electronic building brick that many high precision, these electronic building bricks are along with the raising of technical merit, the speed of its running also increases day by day, and the heat that it produced also increases thereupon, therefore, can under the temperature of its permission, continue running for keeping electronic building brick, constantly do improvement so that will be installed in the fin on electronic building brick surface, by the shape that changes fin, make it have preferable heat dissipation capability, to adapt to the electronic building brick that this kind running speed is fast and caloric value is high.

As shown in Figures 1 and 2, it is conventional aluminium extruded type fin 1a, this fin 1a is made by aluminium, and be installed on the electronic building brick 2a of motherboard 3a, and be its radiating efficiency of raising, thus most fins be provided with at the end face of this fin 1a, to increase the area of heat radiation, and add a fan 4a with the heat sucking-off external world, make electronic building brick 2a can continue running and can keep suitable temperature.

Yet, in any case the shape of improvement fin, its radiating efficiency all can't have improvement significantly, to adapt to that running speed improves constantly and the electronic building brick that caloric value also increases thereupon, because of general employed fin is made with aluminum metal, it has certain radiating efficiency, so can't increase its heat-sinking capability by the profile of improvement fin, but if with the preferable silver of radiating efficiency or copper as material, its required cost then improves relatively, also value-for-money not, therefore, still only can be only second to the material of the aluminium of silver and copper, and can't improve its radiating efficiency significantly with thermal conductivity as fin.

So as from the foregoing, the aluminium extruded type fin of above-mentioned routine obviously is difficult to improve the efficient of its structure with the raising heat radiation again, and can't adapts to the higher electronic building brick of caloric value, is improved so can wait.

The purpose of this utility model is to propose a kind of aluminium extruded type fin of being made up of fin and conducting strip with increase radiating efficiency, and it has high radiating efficiency, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it includes:

One fin, its bottom is provided with a caulking groove at least, and

At least one conducting strip, it is made with the preferable material of thermal conductivity, and matches with the caulking groove of fin, and embeds in the caulking groove in friction tight mode.

Characteristics of the present utility model are that it has higher radiating efficiency.

Fig. 6 is the three-dimensional exploded view of another embodiment of the present utility model;

Fig. 7 is the three-dimensional exploded view of another embodiment of the present utility model.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.See also Fig. 3 and Fig. 4, it is respectively and is three-dimensional exploded view of the present utility model and three-dimensional combination figure.The utility model provides a kind of aluminium extruded type fin that increases radiating efficiency that has, this fin 1 is made by aluminium, its bottom is provided with recessed caulking groove 10, other is combined with the made conducting strip 11 of the preferable material of heat-conducting effect such as copper, this conducting strip 11 is to embed in the caulking groove 10 of fin 1 in friction tight mode, and its bottom surface is concordant with the bottom surface of fin 1, and closely fuses.

As shown in Figure 5, when fin 1 is installed in electronic component 2 tops of motherboard 3, because conducting strip 11 is directly to contact with electronic building brick 2, so the part heat that electronic building brick 2 is sent can be shed, and diffuse to fin 1 rapidly, to reach the purpose of its heat radiation.

In addition, the shape of this caulking groove 10 and conducting strip 11 can be arbitrary shapes (as Figure 6 and Figure 7) such as circle, triangle, square or polygon, and the also size of visual fin and the appropriateness increase and decrease of its quantity.

The utlity model has the aluminium extruded type fin that increases radiating efficiency is the radiating efficiency that can improve fin 1 by conducting strip 11, it is that to have the material of preferable thermal conductivity by copper etc. made, good radiating efficiency can be arranged, so can improve the heat-sinking capability of fin 1 significantly, and this fin 1 is still made with cheap aluminum metal, and only have conducting strip 11 made with expensive copper metal, but because of its volume less, so can't make cost too expensive, still meet economic benefit, also can produce in a large number.

In sum, the utility model is real in improving profile that conventional aluminium extruded type fin only improves fin increasing its heat-sinking capability, thereby can't make problems such as the radiating efficiency of fin improves significantly; The utility model is rare novel creation product.

But above-described only is preferable possible embodiments of the present utility model; be not so promptly inflexible limit claim of the present utility model; so the equivalent structure that uses the utility model specification and accompanying drawing content to be carried out such as changes, all must belong in the scope of claims protection of the present utility model.
