Abstract

A radiator for a high-power LED street lamp comprises a base, heat conducting tubes and fin groups. Two U-shaped grooves with outward openings are bilaterally symmetrically arranged on the upper surface of the base in a left-and-right direction, the U-shaped heat conducting tubes are welded and embedded into the U-shaped grooves of the base, the fin groups in an integral square-wave shape tightly press the heat conducting tubes to be riveted onto the upper surface of the base in bilateral direction, and the square top end of each fin group is provided with a square radiating window. The radiator is novel in design and reasonable in structure, guarantees fine radiation effect, further can facilitate processing, save material and reduce cost, and has wide market prospect and popularization value.

Description

A kind of radiator that is used for high-power LED street lamp

Technical field

The utility model relates to a kind of radiator, especially a kind of radiator that is used for high-power LED street lamp.

Background technology

The LED street lamp has characteristics such as high light efficiency, energy-conserving and environment-protective by means of it and is widelyd popularize in city illumination.Yet the LED street lamp especially heat dissipation problem of high-power LED street lamp is perplexing people always.Because the radiating effect difference of LED street lamp directly causes aggravating the light decay of LED road-light light-source, significantly shorten the service life of LED street lamp.At present, the radiator that is used for high-power LED street lamp adopts a global facility of aluminium extruded fin mostly, and this fin not only radiating effect is poor, and consume material, is difficult for processing.

Summary of the invention

At the weak point of existing high-power LED street lamp radiator, the purpose of this utility model provides a kind of radiator that is used for high-power LED street lamp, makes it not only have better heat radiating effect, and can save material, convenient processing.

For achieving the above object, technical solution adopted in the utility model is: a kind of radiator that is used for high-power LED street lamp, comprise base, heat-conducting copper pipe and fins group, and the upper surface of base is provided with two U-lags that opening is outside along the left and right directions left-right symmetry; The welding of U-shaped heat-conducting copper pipe is embedded in the U-lag of base; The fins group that integral body is square-wave form is pressed the upper surface that heat-conducting copper pipe is riveted on base along left and right directions; The square top of described fins group all is provided with square thermal window.

The beneficial effects of the utility model are: owing to adopt said structure, the welding of U-shaped heat-conducting copper pipe is embedded in the U-lag of base, the fins group that integral body is square-wave form is pressed on the heat-conducting copper pipe, make the heat that led light source produced that is positioned at the base lower surface center to dispel the heat, thereby guarantee better heat radiating effect by the whole fins group of the outside fast guiding of U-shaped heat-conducting copper pipe; Fins group is riveted on the split design of base, not only can save material, reduces cost, and makes that processing is convenient.The utility model modern design, rational in infrastructure, under the prerequisite that guarantees great heat radiation effect, can also be convenient to processing, save material, reduce cost, have extensive market prospects and promotional value.

Description of drawings

Accompanying drawing is a three-dimensional exploded view of the present utility model.

Each label is respectively among the figure: (1) base, (2) heat-conducting copper pipe, (3) fins group, (4) U-lag, (5) window.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to accompanying drawing 1, a kind of radiator that is used for high-power LED street lamp of the utility model comprises base 1, heat-conducting copper pipe 2 and fins group 3, and the upper surface of base 1 is provided with two U-lags 4 that opening is outside along the left and right directions left-right symmetry; 2 welding of U-shaped heat-conducting copper pipe are embedded in the U-lag 4 of base 1; The fins group 3 that integral body is square-wave form is pressed the upper surface that heat-conducting copper pipe 2 is riveted on base 1 along left and right directions; The square top of described fins group 3 all is provided with square thermal window 5.

The above, it only is a kind of preferred embodiment of the utility model, be not that technical scope of the present utility model is imposed any restrictions, every foundation technical spirit of the present utility model all still belongs in the scope of the utility model technology any trickle modification, equivalent variations and modification that top embodiment did.

Claims

1. a radiator that is used for high-power LED street lamp comprises base, heat-conducting copper pipe and fins group, it is characterized in that: the upper surface of base is provided with two U-lags that opening is outside along the left and right directions left-right symmetry; The welding of U-shaped heat-conducting copper pipe is embedded in the U-lag of base; The fins group that integral body is square-wave form is pressed the upper surface that heat-conducting copper pipe is riveted on base along left and right directions; The square top of described fins group all is provided with square thermal window.
