Abstract

The utility model provides a radiating device, comprising a base, a plurality of heat radiating fin tablets continuously arranged on the base in separation, a plurality of diversion parts being formed on the radiating fin tablets, wherein each radiating fin tablet is provided with two sides back to back, and each diversion part is provided with an air opening the two sides of the radiating fin tablets, and a convex tablet stretching out between the air opening and the radiating fin tablets which stretches out of one side of the radiating fin tablet and can be covered on the air opening permeably so that the radiating area and the air disturbance effect can be increased and the radiating efficiency can be improved.

Description

Heat abstractor

[technical field]

The utility model relates to a kind of heat abstractor, and particularly relating to a kind of area of dissipation increases, and the air turbulence effect promoting, can improve the heat abstractor of radiating efficiency.

[background technology]

The heat generating component of general main frame inside, as central processing unit, in the running, can produce heat, for avoiding this heat generating component Yin Wendu to rise, and damage or, usually on this heat generating component, establish a heating radiator, and establish a radiator fan near being adjacent to this heat generating component, to heat sink to the external world, as shown in Figure 1, general heating radiator 1 includes the base 11 that can be located on the heat generating component 2, and a plurality of radiating fins 12 that take shape on this base 11, and base 11 is attached on the surface of heat generating component 2, conduct on this base 11 with the heat that heat generating component 2 runnings are generated, reach these radiating fins 12 again, and heated sink in the surrounding air by the surface of each radiating fin 12, the while is by the running of the radiator fan 3 of contiguous heat generating component 2, air is flowed 12 of adjacent two radiating fins, the heat on all radiating fins 12 is dissipated to the external world with the convection current of borrowing air.

Along with above-mentioned heat generating component 2 high-orderizations as central processing unit, the lifting of computer-internal radiating efficiency, also phase shape ground is more important, according to the above, flowing of the area of dissipation of the radiating fin 12 of this heating radiator 1 and surrounding air, can influence the radiating efficiency of this heating radiator, in the past for improving the radiating efficiency of this heating radiator 1, be by the area that increases these radiating fins 12, improve the wind flow of radiator fan 3, yet, but cause making the volume of this heating radiator 1 to increase, and the comparatively complicated inconvenience that causes in the use in the improvement, and the trouble on making.

[utility model content]

A purpose of the present utility model is to provide a kind of heat abstractor that improves radiating efficiency.

Another purpose of the present utility model is to provide a kind of heat abstractor that can improve area of dissipation under the situation that does not change size.

Of the present utility model being characterised in that: this heat abstractor includes a base, a plurality of radiating fin that is connected with on this base, and a plurality of diversion divisions that take shape on these radiating fins.Each radiating fin has two opposing sides, and is connected with discretely on this base, has a conduit between two adjacent radiating fins.Each diversion division has a ventilating opening that runs through the two side faces of these radiating fins, and a lug that extends between the radiating fin of these ventilating opening both sides, and this lug protrudes on the side of this radiating fin, and ventilative the covering on this ventilating opening.

[description of drawings]

Below by most preferred embodiment and accompanying drawing heat abstractor of the present utility model is elaborated, in the accompanying drawing:

Fig. 1 is that general heating radiator is installed in the synoptic diagram on the heat generating component.

Fig. 2 is a stereographic map, and a preferred embodiment of the utility model heat abstractor is described.

Fig. 3 is the side view of Fig. 2.

[embodiment]

As shown in Figure 2, the utility model heat abstractor 5 includes a base 51, a plurality of radiating fin 52 that erectly is connected with on this base 51, and a plurality of diversion divisions 53 that take shape on these radiating fins 52, above-mentioned have a plurality of radiating fins and diversion division is a most preferred embodiment of the present utility model, but enforcement of the present utility model is not with the above-mentioned system of exceeding, the utility model also can utilize a radiating fin and a plurality of diversion division to implement, and does not illustrate in addition at this.

Each radiating fin 52 has two opposing sides 521,522, and these radiating fins 52 uprightly and discretely are connected with on this base 51, and two 52 adjacent of radiating fins have a conduit 523.

Each diversion division 53 is to form by punching press, during punching press the two opposite sides, the fin 52 lamellar body left and right sides of diversion division 53 positions are thrust, a plurality of arrow gauges that both sides still link to each other with fin 52 lamellar bodies about only forming, then these arrow gauges are gone out to same direction, make to form and have a two side faces 521 that runs through these radiating fins 52,522 ventilating opening 531, an and lug 532 that extends in these ventilating opening 531 1 sides, and this lug 532 protrudes on the side 521 of this radiating fin 52, and can hide on this ventilating opening 531 with ventilating, as above-mentioned, each radiating fin 52 is provided with a plurality of diversion divisions 53, these diversion divisions 53 can be matrix form on each radiating fin 52 arranges, or is staggered.

As shown in Figure 3, as described in top background technology, the bottom of the base 51 of this heat abstractor 5 is fixedly arranged on the heat generating component 4, this heat generating component 4 can be the CPU (central processing unit) of a main frame, and be provided with a radiator fan 6 in contiguous these heat generating component 4 places, with auxiliary these heat abstractor 5 heat radiations.

The heat that is produced when this heat generating component 4, can reach this base 51 by conduction, reach again on these radiating fins 52, these radiating fins 52 carry out heat interchange with ambient air, and heat sink in the ambient air, and by the action of this radiator fan 6, more quicken the carrying out of heat interchange, to promote the radiating effect of this heat abstractor 5, moreover, the lug 532 of these diversion divisions 53, the surface area that makes these radiating fins 52 contact with surrounding air increases, and therefore can improve the radiating effect of this heat abstractor 5.In addition, during these radiator fan 6 starts, the formed air-flow of air flow all can flow to another side 522 through these ventilating openings 531 by a side 521 of these radiating fins 52, and on another radiating fin 52 surfaces that arrive, therefore, air-flow can be with the path shown in the arrow in scheming, flow in 523 of the conduits of these radiating fins 52 through the ventilating opening 531 of these diversion divisions 53, increase the perturbation action of air-flow, relatively improve heat-conduction coefficient, increase radiating efficiency.

Conclude above-mentioned, heat abstractor of the present utility model is on all radiating fins, form a plurality of diversion divisions, can increase area of dissipation on the one hand, improve the effect of heat interchange, can promote the perturbation action of air on the other hand, to promote thermal convection, make heat exchange effect better, and then reach the effect that improves radiating efficiency, so very practical really and progressive.
