Abstract
The utility model discloses the heat radiation accelerating structure of radiation fins. The heat radiation accelerating structure is provided with threads which are crossed or declinate with the direction of cooling liquid on the heat radiation surface of a sheet-shaped radiation fin which is shaped by stamping, or a rough heat radiation surface is formed. By means of the threads or the rough heat radiation surface, the cooling liquid can stay longer time on the radiation fin because of standing wave action and a friction effect, and therefore, the cooling liquid can absorb more heat on the radiation fin, so that the effect of accelerating heat radiation can be achieved.
Description
Technical field
The utility model relates to a kind of heat radiating fin structure, is meant that especially the fin with preferable radiating effect quickens radiator structure.
Background technology
Radiator is the important device in the electronic equipment, and it mainly is to cooperate the effect of fan that electronic device exterior is discharged in the heat pressure that the electronic equipment operation process is produced, and this electronic equipment can run well under normal temperature.The radiator that is used in the earliest in the electronic equipment mostly is by milling the radiating block with grid sheet that processes by transcalent aluminium, or by the radiating block of aluminum extruded shaping, because the weight of this kind radiating block is heavier and process time is long, therefore occur at existing another the novel radiator of the prerequisite of considering cost.This new radiator 1, as shown in Figure 1, fin 11 slices of being made through punching press by the thin-sheet metal material are arranged in a combination, between per two fin 11, be formed with space 12, and the air-flow 21 that is blown out by fan 2 from this space 12 by and take away the heat on fin 11 surfaces, the radiator of being formed by means of this thin type fin 11 1 contacts with electronic component like this, the heat transferred that electronic component running is produced is to each fin 11, the air-flow 21 that utilizes fan 2 to blow out is again taken away the heat in the fin 11, goes round and begins again to reach the heat that the produces eliminating with electronic component running institute.
Above-mentioned stamping forming thin fin is comparatively economized material and is saved time on making, and because of its thickness thin than the traditional heat-dissipating sheet, therefore, also more traditional good of its radiating effect, but applying to long-pending thermal velocity faster in the electronic component time, also can't reach the stage of long-pending heat and heat radiation balance, its main cause is all to form comparatively smooth plane at the both sides of fin 11 heat-delivery surface, therefore cooling blast 21 in the space 12 that inserts and puts by it by the time flicked the heat-delivery surface of fin 11 with fast speeds, therefore, the heat that cooling blast 21 can be taken away in moment is limited, when this radiator 1 is used for the slower electronic component of long-pending thermal velocity, but the speed that the continuous cooled gas flow of its nationality is come its accumulated temperature of balance, but if meet accumulated temperature speed faster during electronic component, its cooling effect just is not so good as expection institute to be thought, may could improve its cooling effect by increasing modes such as fin quantity or increase fan power.
Summary of the invention
For this reason, the acceleration radiator structure of fin mainly is in order to solve the existing existing above-mentioned deficiency of radiator in the utility model.
The acceleration radiator structure of fin in the utility model is to be formed with non-level and smooth heat-delivery surface on the heat-delivery surface of stamping forming thin slice shape fin.This non-level and smooth heat-delivery surface can be one to have the surface of lines, and this ridge orientation and cooling blast direction be not parallel to each other, and simultaneously, this non-level and smooth heat-delivery surface also can be one to have the surface or the coarse surface of sags and crests lines.
No matter the heat-delivery surface of fin is concavo-convex rough surface or the surface with lines in the utility model, the frictional force that produces in the time of all can increasing cooling fluid and flow through, and make fluid generation standing wave (standing wave) effect, allow fluid extend in the time that heat-delivery surface stops, thereby can absorb more heat and discharge outside the radiator, and then reach the purpose that promotes heat sinking benefit.In addition, owing to form coarse or textured surface can't form too much operation or weight to the making of fin and increase volume, but can promote its radiating effect, have more economy, effectively than increasing fin quantity or improving fan power in fin surface.
Description of drawings
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structure and the cooling effect schematic diagram that passes radiator;
Fig. 2 is the front view of radiator in the utility model;
Fig. 3 is the front view of another embodiment of radiator in the utility model.
Embodiment
As shown in Figures 2 and 3, fin 3 is formed with twill 32 in the utility model on the surface, one or both sides of its heat-delivery surface 31, this twill 32 can be as shown in Figure 2 the rhombus twill, it also can be the twill of single direction, even twill not necessarily, promptly can be the lines lines of Any shape, but this lines preferably and the flow direction of the cooling fluid 4 that blown out of fan be not parallel to each other, otherwise can't reach the required effect of the utility model.Twill 32 on heat-delivery surface 31 can make the cooling fluid 4 that passes through be rubbed and can't pass through fin 3 with normal speed, moreover, have the direction that the heat-delivery surface 31 of twill 32 can make cooling fluid 4 advance and be interfered, and make fluid must utilize the more time by fin 3.Comprehensive above-mentioned two factors, increase the time of contact of cooling fluid 4 and fin 3, thereby produce the enough heat absorption time, so temperature too much in the fin 3 can be absorbed and discharge, and brings into play preferable radiating effect.
As shown in Figure 3, the structure of another preferred embodiment in the utility model promptly is formed with recessed or protruding point 52 on the heat-delivery surface 51 of fin 5, this sags and crests 52 is identical with lines, have and make the cooling fluid stop effect of 4 stroke long periods, thereby can increase the heat-sinking capability of fin.This sags and crests 52 on heat-delivery surface 51 then can be considered a kind of fine particle or a kind of coarse heat-delivery surface at heat-delivery surface 52 if more detailed-oriented.
In sum, a kind of non-smooth structure that is formed on the fin heat-delivery surface: as the lines of twill, asperities, coarse particles or Any shape, can both promote the endothermic effect of cooling fluid, to increase the heat radiation function of fin.
