Abstract

A radiating fin for an LED radiator comprises a planer fin main body. The fin main body is equipped with a plurality of ventilating holes and a plurality of heat conductive pipe holding holes. The radiating fin for an LED radiator is characterized in that a plurality of connecting fins perpendicular to the fin main body are arranged along one side of the periphery of the fin main body at intervals, the top of each connecting fin is provided with a 'T'-shaped connecting fastener, and the bottom of each connecting fin is equipped with a 'T'-shaped connecting hole. By utilizing the technical scheme that the fin main body extends to form the connecting fins on the periphery of the fin main body at intervals, when the radiator is combined, the T-shaped connecting hole on the base portion of oneconnecting fin is used for holding the 'T'-shaped connecting fastener on the top of the other connecting fin, the connecting fins are overlapped and interlocked, and the combined radiator is high inconnection strength and uniform in radiating passage. Besides, after the ventilating holes and the heat conductive pipe holding holes are additionally equipped with turned edges, heat transmission andradiating effects of the radiating fin are more obvious by utilizing the heat conduction function of the turned edges of the ventilating holes and the enlarged heat conduction area of the turned edges of the holding holes.

Description

LED radiator fin

[technical field]

The utility model relates to a kind of LED radiator fin.

[background technology]

At present, advanced luminescent material LED shows bright development prospect, particularly great power LED, along with continuing to increase of technology, investigation of materials dynamics, application is also constantly being widened, and product has related to industries such as Landscape Lighting, mine lamp, street lamp and emergency light, favored by the user.Certainly, also have some difficult points in the great power LED product development process, radiator structure is exactly one of problem wherein.In the prior art, the radiator that is used to install great power LED is combined mutually by the multi-disc fin, and compound mode has two kinds of welding, overlap joints.Welding manner exists assembling complexity, operation inconvenience, and the problem that the production cost of wasting time and energy is high is if rosin joint also can influence product quality; Overlapping mode is owing to existing heat radiating fin structure reason, have that linking intensity is low, heat dissipation channel is inhomogeneous and and the heat pipe contact area little, and influence the problem of radiator heat-dissipation effect.

[summary of the invention]

For overcoming the problems referred to above that prior art exists, the utility model aims to provide a kind of LED radiator fin with new structure, and the radiator that utilizes this fin assembling to form has the linking intensity height, heat dissipation channel is even, the advantage of good heat dissipation effect.

For achieving the above object, the utility model has adopted following technical scheme: this LED radiator fin, comprise plane sheet main body, the sheet main body is provided with a plurality of ventilation holes and heat pipe receiving opening, it is characterized in that: along a side of sheet body peripheral edge, have the multi-disc brace perpendicular to sheet main body compartment ground, the top of brace is provided with the junction button of " protruding " font, and the base portion of brace (3) has the convex connecting hole.

Aforesaid LED radiator fin is characterized in that: have the ventilation flange on the limit, hole of described ventilation hole.

Aforesaid LED radiator fin is characterized in that: have the receiving opening flange on the limit, hole of described heat pipe receiving opening.

Beneficial effect: compared with prior art, the utility model is owing to adopted in the sheet body peripheral edge, the technical scheme of extending some braces by sheet main body compartment, during combined heat radiator, the convex connecting hole of brace base portion is used to admit the convex junction button on another brace top, the sheet sheet is stacked, all linked with one another, the radiator linking intensity height that combines thus, heat dissipation channel is even, moreover, after setting up flange on ventilation hole and the heat pipe receiving opening, utilize the heat conduction function of ventilation hole flange, heat-conducting area after the receiving opening flange enlarges makes heat transfer, radiating effect is more obvious.

Among the figure: sheet main body 1, ventilation hole 2, ventilation flange 22, brace 3, limited step 31, connecting hole 32, junction button 33, heat pipe receiving opening 4, receiving opening flange 41, stuffing hole 42.

[embodiment]

Referring to Fig. 1, and in conjunction with Fig. 2, Fig. 3, Fig. 4 and Fig. 5.Every fin comprises plane sheet main body 1, and sheet main body 1 is provided with a plurality of rectangular-shaped ventilation holes 2, heat pipe receiving opening 4.Wherein, 22 guide functions of ventilation flange, receiving opening flange 41 is used to enlarge the contact area of fin and heat pipe tube wall; The purpose of the stuffing hole 42 on the heat pipe receiving opening 4 is set, adds scolder when being to make things convenient for the welding of heat pipe and fin.

Brace 3 is formed by 1 extension of sheet main body, all braces 3 are positioned at sheet main body 1 one sides, and become 90 degree with sheet main body 1 plane, and compartment is evenly arranged in the periphery of sheet main body 1, certainly, what, quantity etc. is set decides according to the fin size of brace 3 of brace and brace spacing distance.The top of every brace 3 is the junction button 33 of " protruding " font, the bottom of brace 3 is the flat board that the middle part has " protruding " font hole, junction button 33 base portion both sides have limited step 31, and the setting of limited step 31 makes the radiator heat-dissipation passage height everywhere after the assembling consistent.

Referring to Fig. 6, and in conjunction with Fig. 4.After multi-disc sheet main body 1 was assembled into radiator, " protruding " font junction button 33 of every brace 3 was folded in the convex connecting hole 32 that is embedded in adjacent blocks of main body 1 brace 3 in addition.
