Abstract

The utility model discloses a folding pressurized heat dissipation fin, which is a rectangular heat dissipation fin used for a heat pipe radiator. A through hole is provided on the heat dissipation fin for the heat pipe to be inserted and fixed. A spacer is bent in the same direction at the center of four sides. Guide plates are bent in the same direction at the two diagonal ends of the heat dissipation fin, and the guide plates at the two adjacent ends are bent in the opposite direction. By setting the guide plates, when the wind side flows through the heat dissipation fin, the wind pressurization effect can be achieved through the guidance of the guide plates, so that high-efficiency heat dissipation can be achieved. Moreover, since the guide plates are directly formed by bending the heat dissipation fins themselves, the volume of the components will not be increased, and the purpose of miniaturization can be achieved.

Description

Doubling formula supercharging radiating fin

[technical field]

The utility model is about a kind of doubling formula supercharging radiating fin, refers in particular to a kind ofly can guide fan airstream can carry out efficiently radiates heat with supercharging radiating fin.

[background technology]

Because the processing speed of integrated circuit components such as computer CPU, the operation frequency is more and more higher, it is also high more to be accompanied by the heat that is produced, and high heat is for all integrated circuit components, all can cause bad influence, therefore a kind of can be rapidly with heat important by the just apparent ten minutes of the radiating fin of integrated circuit component.

Existing radiating fin, mostly be plate-like structure, carry out heat conduction, and be aided with blowing of fan and dispel the heat by the mode that multi-disc is stacked, in recent years, in order to strengthen radiating effect, existing thermal conductance tubular radiator, it is in order to the heat pipe that conducts heat, fold and be provided with many pieces radiating fin, the band heat behind integrated circuit component, via the conduction of radiating fin, carries out the efficient heat radiation through blowing of passing through fan via the thermal conductance pipe racks again.But, because when the heat radiation wind of fan goes out, if its intensity is not enough, can't rapidly the heat on the radiating fin be left equally, so someone proposes No. the 488497th, the novel bulletin of TaiWan, China " fan forced inducer device ", utilization is arranged on the guiding device of fan air side, reaches the effect of wind power boosting.

Though yet above-mentioned fan forced inducer device can supercharging wind-force, reach the effect of efficient heat radiation, but but can increase fan thickness, make the volume of spare part become big, be not adapted on the electronics spare part of present trend toward miniaturization, therefore if can be on existing tabular radiating fin, but the structure of supercharging wind-force be set, believes and to solve the above problems.

[utility model content]

Because the demand, the purpose of this utility model provides a kind of doubling formula supercharging radiating fin, can guide fan airstream and make wind power boosting, therefore can carry out high efficiency heat radiation, and can not increase the volume of radiating fin, can miniaturize the elements.

In order to achieve the above object, the utility model is to take following technological means to be reached, a kind of doubling formula supercharging radiating fin of the present utility model, it is the rectangle radiating fin that is used for the heat pipe radiator, this radiating fin is provided with the heat supply conduit and places fixing perforation, and towards being bent with distance piece in the same way, it is characterized in that in four sides:

This radiating fin is bent with flow deflector towards reverse bending to being less than side two ends.

The diagonal two ends of this radiating fin court respectively are bent with flow deflector in the same way, and the flow deflector of adjacent both ends is towards reverse bending.

Setting by above-mentioned flow deflector, when wind-force effluent during through radiating fin, can reach the wind power boosting effect via the guiding of flow deflector, therefore can carry out high efficiency heat radiation, and because flow deflector is directly to be formed by radiating fin bending itself, so can not increase the volume of element, can reach the purpose of miniaturization.

[embodiment]

Please referring to shown in Figure 1, the utility model doubling formula supercharging radiating fin is to use the long rectangle radiating fin (10) in the heat pipe radiator, it is provided with the heat supply conduit and places the fixedly perforation of usefulness (11), and four sides central authorities are towards being bent with distance piece (12) in the same way, and its improvement is:

This radiating fin (10) in the side on long limit and position at diagonal position respectively towards being bent with triangle flow deflector (13) in the same way, being positioned at the formed flow deflector of each end dual-side (13) is towards reverse bending.

With regard to present embodiment, wherein the broken line of each triangle flow deflector (13) is the position that is extended to the minor face close end by the long limit central authorities of square radiating fin (10).

Please referring to shown in Figure 2, when the utility model doubling formula supercharging radiating fin (10) is assembled on the heat pipe (20), be as the existing heat pipe radiator, perforation (11) back that directly heat pipe (20) was placed plural number piece radiating fin (10) is fixing, allows the interval that is separated out between each radiating fin (10) between distance piece (12) get final product.

Please referring to shown in Figure 3, the utility model doubling formula supercharging radiating fin (10) is when using, it is the fan (30) that horizontal air-supply is set in a side of radiating fin (10), when fan (30) operates, its heat radiation wind can be via the guiding of flow deflector (13), the supercharging radiating fin (10) of flowing through, the heat that therefore can rapidly heat pipe (20) be conducted to radiating fin (10) leaves.

Owing to directly be bent with flow deflector (13) on the radiating fin (10), so fan (30) uses general fan to get final product, and the practice that directly bends on radiating fin (10), can't increase the volume of element, has the value on the industry.

Please referring to shown in Fig. 4,5, the utility model also can only be formed with the flow deflector (13) of reverse bending at side two ends of radiating fin (10) again, and it can reach the effect of water conservancy diversion supercharging equally.
