Description

A kind of fin being applied to radiator

Technical field

This utility model relates to a kind of fin being applied to radiator, particularly a kind of fin for heat dissipation device of LED lamp.

Background technology

It is known that, LED is low due to its energy consumption, long service life and be subject to the favor of people, but LED in use can produce substantial amounts of heat, those heats must be distributed in time, just it is effective to ensure that the service life of LED, otherwise can cause that the service life of LED is greatly reduced.

The existing high-power LED lamp overwhelming majority is equipped with heat abstractor, those heat abstractors generally all include a radiator body, integrally formed with many fins for dispelling the heat on the sidewall of described radiator body, although those fins can play the effect of heat radiation, but owing to the surface area of those fins is generally relatively larger, heat is transferred to other side with radiator body from the side that fin contacts needs the longer time, thus heat can not distribute readily through the whole surface of full wafer fin, radiating rate is relatively slow, thus have impact on the integral heat sink effect of those heat abstractors, and then make the radiating effect of those heat abstractors can not meet the demand of people well.

Utility model content

In order to solve the problems referred to above, the purpose of this utility model is in that to provide a kind of simple in construction, the fin of good heat dissipation effect simultaneously.

This utility model the technical scheme is that for solving its technical problem

A kind of fin being applied to radiator, including a heat sink body, at least provided with the slot of two spaced certain distances in described heat sink body, described slot extends along the longitudinal direction of heat sink body.

As the improvement of technique scheme, described slot is a groove running through described heat sink body.

As the further improvement of technique scheme, described heat sink body is provided with the slot of three spaced certain distances.

In this utility model, described heat sink body is one-body molded by extruded aluminium, and the cross section of described slot is the hole that a circumference completely closes.

Preferably, described heat sink body is by a stamped bending forming of lamellar body, and the cross section of described slot is a notched hole of circumference.

The beneficial effects of the utility model are: due to this utility model by heat sink body at least provided with two the slot extended along the longitudinal direction of heat sink body, and be at intervals distributed between slot in described heat sink body, therefore, when the super heat-conductive pipe of good heat conduction effect is plugged in described slot, heat is rapidly transferred to the process of its other end from one end of super heat-conductive pipe, heat also promptly can outwards transmit and be transferred to each position of heat sink body from the both sides of slot, and then heat promptly can be distributed outward by the whole surface of heat sink body, it is greatly improved the heat-sinking capability of fin of the present utility model；Additionally when the transverse width of fin is broader, a plurality of slot kept at a certain distance away can be set in heat sink body, and then ensure that the whole surface of fin can be utilized to heat radiation fully, greatly increase the utilization rate of fin.

Detailed description of the invention

Referring to figs. 1 through 3, first preferred embodiment of fin of the present utility model, a kind of fin being applied to radiator, including a heat sink body 10, at least provided with the slot 11 of two spaced certain distances in described heat sink body 10, here, it is preferable that, being provided with two slots being parallel to each other 11 in described heat sink body 10, described slot 11 extends along the longitudinal direction of heat sink body 10.It is further preferred that described slot 11 is a groove running through described heat sink body 10；Certainly above-mentioned slot 11 can also be the blind slot not through described heat sink body 10, i.e. the one end open of described slot 11, and the other end is closed.

When the super heat-conductive pipe 20 of good heat conduction effect is plugged in described slot 11, heat is rapidly transferred to the process of its other end from one end of super heat-conductive pipe 20, heat also promptly can outwards transmit and be transferred to each position of heat sink body 10 from the both sides of slot 11, and then heat promptly can be distributed outward by the whole surface of heat sink body 10, it is greatly improved the heat-sinking capability of fin of the present utility model；When the transverse width of fin is broader, the a plurality of slot 11 kept at a certain distance away can be correspondingly put in heat sink body 10, a plurality of super heat-conductive pipe 20 is plugged in above-mentioned a plurality of slot 11 respectively, and then heat can be transferred to full wafer fin from a plurality of super heat-conductive pipe 20, ensure that the whole surface of fin can be utilized to heat radiation fully, greatly increase the utilization rate of fin.

Further, so that fin of the present utility model manufacture simpler convenience, preferably, described heat sink body 10 is one-body molded by extruded aluminium, the cross section of described slot 11 is the hole that a circumference completely closes, and here, adopts the integrated mode of extruded aluminium to make described heat sink body 10, required slot 11 can be processed in heat sink body 10 simultaneously, simple and convenient.Make outside heat sink body 10 in manner just described except of course that adopt, it is also possible to adopt other modes: as described in heat sink body 10 by a stamped bending forming of lamellar body, the cross section of described slot 11 is a notched hole of circumference.

With reference to Fig. 4 and Fig. 5, the second preferred embodiment of fin of the present utility model, itself and the first preferred embodiment are different in that: be provided with the slot 11 of three spaced certain distances in described heat sink body 10.When the surface area of heat sink body 10 is relatively larger, by arranging three slots being spaced a distance 11 in heat sink body 10, can so that the super heat-conductive pipe 20 being plugged in three slots 11 can transfer heat to full wafer fin, the whole surface of the fin that therefore surface area is relatively larger can also be used for dispelling the heat by ground fully, and then fin can be done more, without the problem that the utilization rate worrying fin is low.

The foregoing is only preferred embodiments of the present utility model, broadly falling within protection domain of the present utility model as long as realizing the technical scheme of this utility model purpose with essentially identical means.
