Abstract

Provided is a radiating fin device, which is a peculiar radiating fin used for the radiating fin group of the computer radiator to dissipate heat, the both sides heat dissipation surface of the radiating fin forms a plurality of convex blades turning outward, the blades are usually arranged in a plurality of rows, so as to make the radiator composed of the radiating fin increase the contacting area with the thermal wind by the blades, thereafter improve the heat dissipation effect.

Description

The fin device

Technical field

The utility model is the fin device in the radiator used of a kind of computer equipment, and it is can increase the blade of endotherm area and increase distinguished and admirable contact-making surface by forming on the heat-delivery surface of the both sides of this fin device, to promote the heat radiation function of radiator.

Background technology

Computer equipment is owing to the demand because of function and processing speed, its inside has usually increased very many devices, and when these devices operate in narrow and small mainframe box together, the high temperature that is produced in its work is unusual surprising, therefore, when desire expanded or increase the function of computer equipment, how the high temperature that is derived effectively discharged, and also was must be also with the problem of considering.

All be provided with radiator in the present computer equipment, with pressure the temperature that relevant apparatus was produced effectively got rid of, heat sink part comprises fan, groups of fins, heat absorption base plate, fastener ... in device.Fan is the temperature that fin is absorbed, and forces to discharge outside the mainframe box.And existing radiator 3, as shown in Figure 1, has a groups of fins that forms side by side by plural pieces fin 30 on top 31, this groups of fins 31 is bonding on the heat absorption base plate 33 of position in the bottom, heat absorption base plate 33 is positioned over above the computer motherboard CPU, by heat absorption base plate 33 the temperature transmission of CPU is adsorbed in groups of fins 31, again in groups of fins 31 with the temperature of aforementioned CPU by groups of fins 31 on band from, and reach so-called radiating effect.

Though help the long-pending hot type of computer equipment to remove on the effect of above-mentioned radiator; precisely because radiating effect shows weak point is arranged; reason exists: the surperficial generally planar shape of this fin 30; and the flow direction of wind (as the arrow of Fig. 1) f mostly is parallel with fin 30 surfaces; therefore; distinguished and admirable by these fin 30 sides; the thermal source on the fin of taking away 30 be very limited; cause the long-pending hot major part on fin 30 to finish by dispelling the heat of long period from body; making fin 30 will amass hot type in the shortest time like this removes; and also make the working temperature of this computer equipment effectively to get rid of under the vicious circle, cause hang-up.

The utility model content

For solving existing fin such as above-mentioned problem, the utility model proposes a kind of new departure, its heat-sinking capability that lays particular emphasis on the fin device promotes, thereby improves the radiating efficiency of entire radiator.Its practice is a plurality of to the blade that turns up and protrude with forming on the both sides heat-delivery surface of existing flat fin device, and this blade can be formed by direct punching out on the fin, perhaps is additional to the surface of fin in addition.The main application of the blade that this is outwards routed up is that fin protrudes out, thus the area increase relatively also increase with distinguished and admirable contact area, and then with this practice the thermal source on the fin, effectively with distinguished and admirable band from promoting its heat dissipation.Increase in order to utilize the blade that stretches out to make with the distinguished and admirable area that contacts, this blade can be construed as number row's arrangement, but the blade that turns up of the fin of each adjacent arrangement is not interfered each other, in order to distinguished and admirable smooth and easy flowing, and the shape of this blade and arrangement position thereof are the override consideration to guide distinguished and admirable.

By the above-mentioned this blade that on fin, turns up, can produce more outstanding radiating effect really, use the made radiator of this kind fin, also have good heat dissipation.

Description of drawings

Fig. 1 is the surface structure stereogram of the groups of fins of existing radiator;

Fig. 2 is the surface structure stereogram of fin of the present utility model;

Fig. 3 is the vertical view of the fin of Fig. 2;

Fig. 4, Fig. 5 are other preferable enforcement structure front views of fin of the present utility model.

Embodiment

The preferable enforcement structure of the utility model, as shown in Figure 2, the surface of fin 1 is provided with at interval, and layout is the fin-shaped blade 10 that turns up, the arrangement of this blade 10 can utilize staggered mode, so that it forms the setting of multi-disc in limited area, select between last row's blade 14, to begin in the space 11 to arrange as among Fig. 2 time one row's blade 12.Arrangement mode another feature of this blade 10 is, last row's blade 14 and time one row's blade 12 its to turn up in the direction on fin 1 surface be to be relative (as Fig. 3), that is last row's blade 14 is routed up to the left of fin 1, then 12 in time one row's blade is routed up to the right-hand of fin 1, it is opposite to the design of routing up that this adjacent row's blade is mutually, main purpose is when providing fin 1 to form groups of fins, its left and right sides all has the blade that turns up so that produce more contact area with distinguished and admirable f, and the long-pending heat on the fin 1 is left fast.Therefore, heat radiation power provided by the utility model be otherwise flat shape fin plural number doubly, but not only one times.In addition by

blade

12,14 shapes of Fig. 3 as can be known, it must outwards be relaxed by fin 1 body surface rout up, and to reduce the resistance after the distinguished and admirable f collision, makes distinguished and admirable can the discharge smoothly after the heat absorption.

The utility model is provided with the blade that turns up promoting its endotherm area in fin 1 surface, and then reaches better heat radiating effect, and its fact is not sayed and can be explained.Only, its blade shape that turns up is not limited to above-mentioned fin-shaped shape, it is alleged and included that any blade that can reach this heat radiation function is the utility model, as Fig. 4, rimmer knife shape blade 16 shown in Figure 5 and Long Circle blade 18 or anyly can imagine the shape of spreading to, fin 2 its wind directions wherein shown in Figure 4 are from top to bottom, therefore, the arrangement of its blade 16 is the declivity to central authorities, the long-pending heat that distinguished and admirable guiding central authorities are forced to drive away this place still all right.

Claims

1, a kind of fin device is characterized in that, is formed with the blade that protrudes to turning up on the both sides heat-delivery surface of this fin.

2, fin device as claimed in claim 1 is characterized in that, wherein the both sides heat-delivery surface is provided with number row's the blade to the protrusion that turns up.
