Abstract
The utility model relates to a novel radiating profile which comprises an upper uniform heat installation platform, a lower uniform heat installation platform, air flow channels, inner radiating fins and wave-shaped protuberances on the inner radiating fins. An electronic device transfers heat to the uniform heat installation platforms. Heat is further transferred to the inner radiating fins and the wave-shaped protuberances on the surfaces of the inner radiating fins, and contacts air for heat exchanging, so that the purpose of radiating is realized. The air flow channels are formed between the inner radiating fins. Heated air flows out from one end of each air flow channel, and negative pressure is formed in the air flow channel. Cold air is taken in from the other end, so as to enhance the radiating effect.
Description
Technical field
The utility model belongs to the heat sink section bar technical field, relates in particular to a kind of heat sinking section bar.
Background technology
Electronic equipment needs radiator to accelerate heat radiation, and radiator is usually blocked and makes by actual demand by heat sink section bar, and heat sink section bar has the advantages that thermal conductivity is good, lightweight, be applicable to a large amount of manufactures.Common heat sink section bar be shaped with radiating fin mostly be open, structural strength deficiency radiating fin and heat sink section bar, and because radiating fin is open, can't utilize cold air supplemental heat air and the balance that causes flows, so radiating effect is not good.
The utility model content
(1) technical problem that will solve
Goal of the invention of the present utility model is to provide a kind of structural strength high, the heat sinking section bar that radiating fin closure and heat sink section bar global sections are rectangular,
(2) technical scheme
For addressing the above problem, the utility model adopts following technical scheme:
A kind of heat sinking section bar, comprise even hot mounting platform (1), lower even hot mounting platform (2), interior radiating fin (3), described even hot mounting platform (1) and lower even hot mounting platform (2) be arranged in parallel, described interior radiating fin (3) interval is located between described even hot mounting platform (1) and lower even hot mounting platform (2), is provided with air flow channel (5) between adjacent described interior radiating fin (3).
The surface of described interior radiating fin (3) is provided with wavy projection (4).
Described section bar cross section is rectangular, the ratio L1/L2=9/7 of the height L2 of the height L1 in described section bar cross section and described interior radiating fin (3).
(3) beneficial effect
The utility model is compared to prior art, has following beneficial effect: 1. the utility model profile closure and cross section are rectangle, and are provided with interior radiating fin, have increased structural strength, have formed even hot mounting platform and lower even hot mounting platform simultaneously; 2. by the closure of the utility model profile, can utilize cold air to suck that the supplemental heat air flows out and the balance that causes flows increases radiating effect; 3. be provided with wavy projection on the surface of interior radiating fin, to increase the surface area contacted with air.
The accompanying drawing explanation
Fig. 1 is outside drawing of the present utility model.
Fig. 2 is profile of the present utility model.
Fig. 3 is A of the present utility model section enlarged drawing.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for the utility model is described, but are not used for limiting scope of the present utility model.
As shown in Figure 1 to Figure 3, a kind of heat sinking section bar, material is aluminium, comprise even hot mounting platform 1, lower even hot mounting platform 2, interior radiating fin 3, described even hot mounting platform 1 and lower even hot mounting platform 2 be arranged in parallel, described interior radiating fin 3 intervals are located between described even hot mounting platform 1 and lower even hot mounting platform 2, between adjacent described interior radiating fin 3, are provided with air flow channel 5.
The surface of described interior radiating fin 3 is provided with wavy projection 4.
Described section bar cross section is rectangular, the ratio L1/L2=9/7 of the height L1 in described section bar cross section and the height L2 of described interior radiating fin 3.
The upper surface of described even hot mounting platform 1 all can contact with electronic equipment with the lower surface of lower even hot mounting platform 2, electronic equipment transfers heat to upper and lower even hot mounting platform, heat further is delivered on interior radiating fin 3 and the surperficial wavy projection 4 be provided with thereof, contact and carry out heat exchange with air, reach the heat radiation purpose.Meanwhile, heated air expands, due to heat sinking section bar profile closure, heated air will flow out from an end of heat sinking section bar, form negative pressure in the air flow channel 5 formed between interior radiating fin 3, and suck cold air from the other end, utilize cold air to suck that the supplemental heat air flows out and the balance that causes flows increases radiating effect.The height L1 at place, heat sinking section bar square-section is 9: 7 o'clock with the ratio of the height L2 of interior radiating fin 3, the radiating effect maximum that balance flows and increases.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
