Abstract

The utility model relates to a punching process structure for a radiator capable of increasing the contact area. The punching process structure comprises a heat pipe 6 and a heat radiation fin 3. When the heat radiation fin 3 is punched, the edge wall of a turned-over edge 4 is inclined inward by a certain angle n (smaller than 90 but bigger than or equal to 45 degrees). The inner diameter size of the punched hole on the heat radiation fin 3 is slightly larger than the outer diameter size of the heat pipe 6 so as to be convenient for the penetration thereof, and a plurality of triangular notches 5 are formed on the turned-over edge 4 of the punched hole. When the heat pipe penetrates through the heat radiation fin, the turned-over edge of the punched hole of the heat radiation fin tightly presses the heat pipe like a plurality of elastic metal sheets, thereby increasing the contact area and the contact intensity of the heat pipe and the heat radiation fin, and greatly enhancing the heat radiation performance.

Description

A kind of radiator that can increase contact area is worn tailor's structure of planting

Technical field

The utility model relates to the structure of radiator, and more particularly, what relate to a kind of radiator that can increase contact area wears tailor's structure of planting.

Background technology

In the last few years, along with constantly weeding out the old and bring forth the new and the develop rapidly of production technology of IC design in the semiconductor devices, the volume of semiconductor devices is constantly dwindling, and the normal power in its integrated level and when work is continuing to increase, this just need carry out good processing to its heat dissipation problem, and radiator just arises at the historic moment.Traditional radiator mainly adds that by fan a radiating module forms, radiating module may be some radiating fin vertical distribution of seeing usually on base plate, and with base plate structure in aggregates; It also may be a kind of tailor of wearing structure of planting.

Tradition is worn the plant radiator of structure of tailor, it is that with the maximum difference of general radiator its radiating fin separates with base plate, radiating fin can be made by two kinds of different materials with base plate, its structure is punching on radiating fin, pass punching by some heat pipes again, last heat pipe two ends are converged and are connected in base plate.This structure helps to strengthen the heat dispersion of radiator, has also improved the heat conductivility of radiator.In traditional production and processing, formed flange is vertical with radiating fin after the radiating fin punching.Owing to be difficult to accurately to guarantee the internal diameter size size of heat pipe outside dimension and radiating fin punching, when heat pipe outside dimension during less than the internal diameter size of radiating fin punching, heat pipe can not be combined closely with radiating fin, causes heat dispersion to decline to a great extent; When heat pipe outside dimension during greater than the internal diameter size of radiating fin punching, heat pipe can't pass radiating fin again.In addition, because radiating fin (referring generally to the metal species plate) is thinner, add also easy modification in man-hour.

Summary of the invention

The technical problems to be solved in the utility model is, at the above-mentioned defective of prior art, what a kind of radiator that can increase heat pipe and radiating fin contact area was provided wears tailor's structure of planting.

The technical scheme that its technical problem that solves the utility model adopts is: the tailor's structure of planting of wearing of radiator is made up of heat pipe and radiating fin.The formed piercing and flanging of radiating fin punching processing slopes inwardly, and the angle of inclination is 45 °-90 °.The outside dimension that the internal diameter size of radiating fin punching is slightly larger than heat pipe passes to make things convenient for heat pipe, and has opened the leg-of-mutton breach in several places at the piercing and flanging place, and this vee can be opened before punching press also and can open after punching press.

Because radiating fin punching internal diameter is slightly larger than the heat pipe external diameter, heat pipe can pass radiating fin very easily during practical operation; On the other hand, because the piercing and flanging on the radiating fin slopes inwardly, and with the vee design, the radiating fin piercing and flanging can outwards open by nature when cooperating with heat pipe, because the intrinsic elasticity of sheet metal itself, piercing and flanging can tightly suppress heat pipe as the number of metal shell fragment, has increased the contact area and the contact strength of heat pipe and radiating fin, has strengthened heat dispersion greatly.

Implement radiator of the present utility model and wear tailor's structure of planting, have following beneficial effect:, make installation very light because the internal diameter size of radiating fin punching is slightly larger than the outside dimension of heat pipe.Because piercing and flanging can tightly suppress heat pipe as the number of metal shell fragment, increase the contact area and the contact strength of heat pipe and radiating fin in addition, strengthened heat dispersion greatly.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the local figure of the punching of traditional radiator heat-dissipation fin;

Fig. 2 is the local figure of the punching of the utility model radiator heat-dissipation fin;

Fig. 3 is the cutaway view schematic diagram of the utility model radiator heat-dissipation fin;

Fig. 4 is the part figure of the utility model radiator heat-dissipation fin and heat pipe combination.

The specific embodiment

As shown in Figure 1, the flange 2 after traditional radiator heat-dissipation fin 1 punching processing is vertical with radiating fin 1.

As shown in Figure 2, the radiating fin 3 of radiator of the present utility model, the formed piercing and flanging 4 of radiating fin punching processing slopes inwardly, and the angle of inclination is 45 °-90 °.On piercing and flanging 4, have several vees 5.

As shown in Figure 3, radiator of the present utility model, radiating fin 3 and flange 4 angles at 45 in the present embodiment.

As shown in Figure 4, in practical operation, when heat pipe 6 passed radiating fin 3, because the flange 4 that radiating fin 3 produces has vee 5 designs, piercing and flanging 4 is easier during installation outwards opened.Because the intrinsic elasticity of sheet metal itself, piercing and flanging can tightly suppress heat pipe as the number of metal shell fragment, has increased the contact area and the contact strength of heat pipe and radiating fin, has strengthened heat dispersion greatly.

Claims

1, a kind of radiator that can increase contact area is worn tailor's structure of planting, and is made up of heat pipe and radiating fin, it is characterized in that the flange of radiating fin slopes inwardly, and the angle of inclination is 45 °-90 °.
