Abstract
The utility model relates to a heat radiator structure, comprising a heat conducting base and heat radiating fins. A plurality of heat radiating fins which are arranged in crisscross on the heat conducting base can make the air which is driven by the fan when the fan blows downward flow left to right and up and down between each heat radiating fin. The hot gas cannot gather under the heat radiating fins through the fast switching and flow of the air hot and cold molecula between fins. Intervals for the air circulation are arranged between heat radiating fins to make the hot gas dissipate to the circumference. So the fast heat radiation can be finished. The heat radiator structure is suitable for the radiators of computers, electronic instruments or other heating appliance components.
Description
Technical field
The utility model relates to a kind of heat spreader structures, particularly a kind of structure that is provided with the radiating fin of several criss-cross arrangements above heat conducting base.
Background technology
Because the progress of modern computing machine information is quick, the operating rate of its CPU speeds day by day, and the high temperature that produces must be dependent on the cooling effect of dynamical radiator and fan together, just can keep normal working temperature.
With general radiator a (as shown in figure 10), it is extruded with aluminium extruded type and makes, but the radiator a that makes with aluminium extruded type, the fin b of its moulding arranges to equi-spaced apart with folk prescription, when external combination of fans during in the top of radiator a, the air-flow that fan produced is cut apart by each fin b, only can flow between each fin b respectively.Because the flowing space of hot-air is restricted, make hot gas that CPU produced still accumulate in the below of fin b in a large number, can't form heat exchange with the colder air molecule in fin b top, and reach the effect of heat radiation.
See also shown in Figure 11, for solving the above-mentioned problem that radiator produces of commonly using, the dealer is converted into several radiating fins c with a sheet metal Curved Continuous, and the top of this fin c is set as inverted V-shaped, and cut a finedraw d at the flanging place, so that the air-flow that fan e is produced flows between each fin c fast.Though said structure can make the area of dissipation of radiating fin c strengthen, but because but the space of its heat supply air flows is still limited, and the set finedraw breach d in fin c top only can pass through for a spot of space, when producing high temperature when the CPU working at high speed, still fail effectively to make airborne cold and hot molecule exchange, so that hot gas is discharged, its radiating effect is not satisfactory.
Summary of the invention
The purpose of this utility model provides a kind of heat spreader structures that can quicken to dispel the heat.
Above-mentioned purpose of the present utility model is achieved in that a kind of heat spreader structures, it is characterized in that comprising a heat conducting base, and its top is provided with several staggered radiating fins.
A plurality of radiating fins that are criss-cross arrangement that the utility model utilizes the top of heat conducting base to be provided with, make fin up and down cold and hot molecule quick exchange between crisscross radiating fin of air flow, the high temperature that CPU is produced can not accumulate in the below of fin.Hot-air is flowed about between each fin fast in length and breadth, make hot gas to dissipation all around, to reach the effect of heat radiation.
The utility model is elaborated with instantiation below in conjunction with accompanying drawing.

Embodiment
See also first embodiment of the utility model heat spreader structures 1 of Fig. 1～shown in Figure 3, this heat spreader structures 1 comprises a square heat conducting base 2, its top is plane 21, this plane 21 is provided with several radiating fins 3, and these radiating fins 3 are the strip lamellar body of four side rounding of angle arc (also can be square column, strip trapezoid block).These several radiating fins 3 comprise first fins group 4 and second fins group 5, and this two fins group (4,5) comprises the radiating fin 3 that several rectangular array shapes are arranged, the radiating fin 3 interlaced arrangements of above-mentioned first fins group 4 and second fins group 5 respectively.
See also Fig. 4 and Fig. 5, the top of several radiating fins 3 of the present utility model links a fan 6, and the below of heat conducting base 2 links a CPU 7.When CPU 7 ran up, its heat upwards conducted, and makes the below that most hot gas is gathered in each radiating fin 3 via heat conducting base 2.When the air that is driven when fan 6 rotation blows downwards, formed air-flow can flow between each crisscross radiating fin 3 up and down, make the cold and hot molecule quick exchange of the air of 3 of each fins, thus the heat upwards diffusion fast that each radiating fin 3 below is gathered.In addition, because the four side angle of these radiating fins 3 has radian, can make that hot gas is smooth and easy to flow, and the gap 31 that institute forms respectively between each radiating fin 3 when hot gas flows fast, to dissipation all around, can reach the effect of rapid heat radiation via this gap 31.
See also second embodiment of the utility model heat spreader structures 1 of Figure 6 and Figure 7, wherein the radiating fin 8 of this strip (also can be trapezoidal shape) is bent by a plate 81 and is formed, it vertically forms a duct that communicates 82, the area of dissipation of radiating fin 8 and the path that hot gas flows can be increased, thermolysis can be strengthened.
See also Fig. 8 and shown in Figure 9 shown in two kinds of aspects of the 3rd embodiment of the utility model heat spreader structures 1, wherein the upper end of the radiating fin 9 that forms of this plate 91 bendings is provided with a breach 92 longitudinally, can increase the area that air that fan 6 drives blows downwards, and make air have more path, outwards distribute fast to impel hot gas.
The utility model has the advantage of:
1, the arrangement mode of the set radiating fin of the utility model can provide up and down air cold and hot of fin The molecule rapid exchange fluid is moving, so that the upwards diffusion of heat that each radiating fin below is gathered, and in can not making The high temperature store that Central Processing Unit produces helps hot gas to be taken away rapidly below fin.
2, have crisscross gap between set each radiating fin of the utility model, can blow at fan When sending air, make the hot gas rapid flow, and via each gap to around dissipation, to reach the effect of heat radiation.
In sum, the utility model really can reach the expection purpose of creation, provide a kind of can be with radiator institute The heat of assembling, moving by the cold and hot molecule rapid exchange fluid of the air between each radiating fin, to reach heat radiation The heat spreader structures of effect.
