Abstract

Disclosed is an unbalanced radiation fin. An even contact surface is arranged at the bottom parts of the radiating fins which are in wavy arrangement and stand tall and upright on the bottom surface. The wavy fins has continuous surface with at least three integrated or more than three integrated wave crests and are arranged gradually at almost the same intervals. When the surface of the fins is jointed to a central processor, the heat source of the processor is transmitted to towards the fins and the hot air transmitted by the fan on the top escapes from a radiation channel. In the structure the whole radiator area and the channels are increased and thus the radiation efficiency is effectively improved.

Description

Uneven radiating fin

Technical field:

The utility model relates to a kind of heat abstractor, relates in particular to a kind of shape and arrangement of radiating fin of heat abstractor of central processing unit, and is better to reach the low cost of manufacture radiating effect.

Background technology:

The applicant has applied for that in January 8 calendar year 2001 application number is 01200116.3, and denomination of invention is the utility model of " uneven radiating fin ".Its application mainly forms smooth surface of contact in heat radiator bottom, and by the bottom upwards stand plural number by both sides with wait until approximately arrange downwards gradually apart from arc after, and the wavy fin of up bringing together to central authorities, the top of diffusing sheet then is provided with fan, to blow unbalanced axial flow wind at the heat dissipation channel between adjacent fin, with so that axial flow wind in the heat dissipation channel produces the bump of variable speed, the hot-fluid that is accumulated in the heat radiator is overflowed outside the heat dissipation channel fast, yet, the plural fin of the wavy arrangement that heat radiator was convexly equipped with of original bill has two complete crests, the heat radiation and the tropospheric area that cause fin itself to produce are less, and be relatively poor for the heat energy radiating efficiency that central processing unit produces.

Summary of the invention:

The purpose of this utility model is: for the heat radiator of the uneven radiating fin that makes original bill effectively increases area of dissipation and heat dissipation channel uses, and the heat radiator setting had at least the wavy fin of the complete crest more than three or three, in order to the number of increase area of dissipation and heat dissipation channel, but still has the advantage of original bill.

The utility model is achieved in that the main smooth surface of contact that is formed with in heat radiator bottom, and upwards being stood by the bottom has the plural fin that is wavy arrangement, this wavy fin has three complete crests or the above continuous face of three complete crests at least, and wavy fin forms approximately equidistantly to arrange gradually.Wherein, the top of this heat radiator is provided with fan, and to blow axial flow wind at heat radiator, the two side-flank surfaces inboard of this heat radiator convexes with a supporting part for correspondence.This heat radiator inside is provided with the groove cross-shaped with fin, the heat dissipation channel bottom that forms between this heat radiator central authorities adjacent fin is projection comparatively, and to both sides declivity gradually, to increase the sectional area that the central processing unit thermal source is directly conducted to the heat absorption usefulness of heat radiator, in order to improve heat conduction efficiency.

The utility model is a smooth surface of contact because of the bottom, when the surface of contact of heat radiator is fitted in central processing unit, its central processing unit thermal source promptly transmits towards heat radiator, the axial flow wind that give after the fan established rotates its top can blow towards the plural fin place of heat radiator, and makes hot blast after the heat radiation via the heat dissipation channel effusion place circle between fin.The utility model is provided with wavy fin in the continuous face of the complete crest more than at least three or three, and wavy fin is arranged with equidistant approximately circular arc gradually by both sides, and heat radiator entire area and heat dissipation channel are increased, with effective raising radiating efficiency, and also have function and the characteristics that original application has simultaneously.

Embodiment:

As Figure 1-3, be respectively the constitutional diagram of solid of the present utility model, outside drawing and side view.It comprises heat radiator 1, fan 2 and elastic body 3 constitute, the bottom of heat radiator 1 is a smooth surface of contact 11, its top is to be convexly equipped with the plural fin 12 that is wavy arrangement and has the complete crest more than three or three at least, and tilt to extend one by two side-flank surfaces 13 of heat radiator to evagination and be the H type, blocking part 131 and convex with horizontal former supporting part 132 in two side-flank surfaces, 13 inboards, and inner (cut open and establish) has the groove 14 cross-shaped with each fin 12 on plural fin 12, on the above-mentioned supporting part 132 for can be equipped with fan 2, and utilize a U type elastic body 3 to be located in the blocking part 131, the buckling parts 31 of elastic body 3 both sides is stretched out outside the blocking part 131, utilize the buckling end 311 of buckling parts 31 to be fastened in the perforation 21 of fan 2 again, just make fan 2 be positioned at heat radiator 1 directly over, the surface of contact 11 of heat radiator 1 bottom then is fitted in the upper surface of the central processing unit 41 of circuit board 4, has promptly constituted the integral body of this device.

Heat dissipation channel 121 bottoms of 12 formation of above-mentioned heat radiator 1 central adjacent fin are projection comparatively, and to both sides declivity gradually, to increase the cross section that central processing unit 41 thermals source are directly conducted to the heat absorption usefulness of heat radiator 1, in order to improve conduction efficiency.

Shown in Fig. 3-5, be the side view of this device, wind speed flow graph, troposphere wind rose.After the high heat that discloses central processing unit 41 generation when action among the figure is to be entered by heat radiator 1 bottom surface of contact 11, promptly fast thermal source is transmitted on the plural fin 12 of top, the axial flow wind C that utilizes the cooling usefulness that fan 2 produces in a clockwise direction, and the shape mode is down blown in the shape of a spiral, deliver in the heat dissipation channel 121 in each fin 12 gap, promptly cause axial flow wind C to be blown into along fin 12 this moment, if when with axial flow wind C over against plural fin 12 regional when upwards arranging gradually, can diminish because of holding the wind face, then can form one high wind A, otherwise, when axial flow wind C over against plural fin 12 when down arranging gradually, it holds the wind face and can diminish, and then can form one gentle breeze B, and in heat dissipation channel 121, produce the bump of variable speed by high wind A and weak wind B, the hot-fluid that is accumulated in the heat radiator 1 is overflowed outside the heat dissipation channel 121 fast.Plural number fin 12 can by both sides with about isometric circle arcuation arrange gradually the design of continuous face, make the bump of the axial flow wind formation variable speed in the heat dissipation channel 121, and can accelerate the speed of wind convection current, favourable axial flow wind C can enter in the heat dissipation channel 121 in adjacent fin 12 gaps once more fast.The application utilizes to protrude out at least three intact crests or three wavy fins 12 that the above equidistant approximately circular arc of complete crest is arranged gradually on the heat radiator, the area of dissipation and the convection channel of its heat radiator 1 are effectively increased, in order to improve whole radiating efficiency, to form the application's whole implementation state.
