Abstract

The utility model provides a stacked fin type radiator, comprising a plurality of radiating fins which are mutually fastened. Wherein, each radiating fin is provided with an identity and two fastening portions arranged on the identity, each fastening portion comprises a protrusion and a dent portion which are formed by multiple bending, and the protrusion and the dent portion are respectively positioned on two opposite faces of the fastening portion. The protrusion of a radiation fin of the two adjacent radiating fins is matched with the dent portion of the other radiating fin. Other tools are not needed to be used when each radiating fin is mutually fastened in the assembling process of the utility model, and the lock jointing process is simple. The fatigue strength of the fastening portion of each radiating fin is not greatly influenced when the stacked fin type radiator is disassembled, and the stacked fin type radiator can be assembled repeatedly.

Description

The stacking fin type radiator

[technical field]

The utility model refers to a kind of radiator that is used for electronic element radiating especially about a kind of radiator.

[background technology]

Fast lifting along with the electronic component operating frequency, the heat that it produced is also increasing, if the heat that produces is not in time distributed, stability when too high temperature will have a strong impact on the electronic component operation, even also whole element may be burnt, so the heat dissipation problem utmost point of electronic component need solve.

In the traditional heat-dissipating mode, people use finned radiator that electronic component is dispelled the heat usually.This method is at the heat-generating electronic elements end face radiator of fitting, and sets firmly a fan auxiliary heat dissipation then on radiator.This class radiator is to extend upward the fin that several are used to increase area of dissipation on metal base mostly.Its heat dissipation capacity is extremely limited, in order to increase area of dissipation, can only increase the volume of radiator, and the trend that this makes the weight of radiator and institute take up space all to increase greatly and electronic component is day by day lightly changed is disagreed, and is difficult to meet more and more high heat radiation needs.

For addressing the above problem, industry adopts a kind of multi-disc fin stacked radiator that forms in parallel more, as No. the 00254564.0th, Chinese patent.As shown in Figure 1, this radiator comprises the radiating fin 20 of a plurality of mutual fastenings, wherein each radiating fin 20 has a body 21 and by on the body 21, two flangings 22 that are parallel to each other that the vertical bending of lower edge forms, each flanging 22 both sides has extended to form a pair of clamping part 23, on body 21, lower edge near the position of the corresponding clamping part 23 in flanging 22 places dash respectively be provided with can with the button hole 24 of clamping part 23 tablings, during assembling that several pieces radiating fins 20 are stacked in regular turn, and the clamping part 23 of a later radiating fin 20 is chimeric mutually with the button hole 24 of adjacent last radiating fin 20, this radiator can effectively increase area of dissipation, and radiating effect is good.But, need to use bending tool in the snapping process of this radiator, the snapping complexity, production efficiency is low, and the fatigue strength of clamping part 23 is limited, can not repeat repeatedly to install.

[summary of the invention]

The purpose of this utility model is to provide a kind of snapping process simple and can repeatedly repeat the radiator assembled.

The purpose of this utility model is achieved through the following technical solutions: a kind of stacking fin type radiator, the radiating fin that comprises a plurality of mutual fastenings, wherein each radiating fin has a body and is located at two buckling partss on the body, each buckling parts comprises a projection and the depressed part through repeatedly being bent to form, this projection and this depressed part are positioned at the two relative surfaces of this buckling parts respectively, in the two adjacent radiating fins, wherein the projection of a radiating fin cooperates with the depressed part of another radiating fin.

In the utility model assembling process, need not use other instrument when each radiating fin fastens mutually, the snapping process is simple, and is little to each radiating fin buckling parts fatigue strength influence during dismounting, can repeatedly repeat assembling.

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

[embodiment]

See also Fig. 2 to Fig. 4, the utility model provides a kind of stacking fin type radiator 10, and this radiator 10 is to be fastened mutually by a plurality of radiating fins 11 to form.

Each radiating fin 11 is to be bent to form by the good single light sheet material punching press of thermal conductivity such as aluminium, copper, comprises a body 12 and directly bends upper and lower two buckling partss 13 that form by body 12 upper and lower marginal lappets.Form first, second depressed part 132,133 of first, second flat part 130,131 and arc on each buckling parts 13 at interval, buckling parts 13 then forms first, second projection 14,15 of arc at the another side of first, second depressed part 132,133 correspondences.First flat part 130 is parallel with second flat part 131, and first flat part 130 is lower than second flat part 131, and its difference in height equates with the thickness of second flat part 131.Second projection 15 equates with the radian of first depressed part 132.

During assembling, utilize certain pressure upper and lower two buckling partss 13 of back one radiating fin 11 to be pressed to the body 12 of last radiating fin 11, the upper and lower edge of the body 12 of second of a radiating fin 11 projection 15 and last radiating fin 11 contacts after this moment, under the effect of pressure, upper and lower two buckling partss 13 of back one radiating fin 11 can outwards open certain angle.When second projection 15 of back one radiating fin 11 slips into first depressed part 132 of last radiating fin 11, on this back one radiating fin 11, two buckling partss 13 inwardly close up certain angle down, this moment, first depressed part 132 of last radiating fin 11 and first flat part 130 fitted tightly with second projection, 15 and second flat part 131 of back one radiating fin 11 respectively, and on the body 12 of last radiating fin 11, lower edge is resisted against first projection 14 of back one radiating fin 11 respectively, thereby former and later two radiating fins 11 are snapped together tightly, assemble each sheet radiating fin 11 in regular turn according to this method then.

Because the difference in height of first flat part 130 and second flat part 131 equals the thickness of second flat part 131, therefore, after assembling finished, second flat part 131 of each radiating fin 11 correspondence was positioned at same plane, promptly constitutes the upper surface and the lower surface of the utility model radiator 10.
