The utility model is described in further detail below in conjunction with drawings and Examples.

The specific embodiment

Following examples introduce in the process at concrete structure or parts, only understand of the present utility model with reference to the property illustration as those skilled in the art, those skilled in the art can also design or technical scope or the various of technical spirit that patterning is not exceeded the utility model are equal to or the similar techniques feature under the enlightenment of embodiment description technique scheme.Thus, be unfavorable if limit the protection domain that the utility model claim includes with this exemplary illustration.Be equal to or be similar to the protection domain that the technical solution of the utility model still belongs to the utility model claim.

As shown in Figure 1, high-power LED (Light-Emitting Diode) lamp radiator (hereinafter to be referred as radiator) 1 is the core heat dissipation element with columniform plume 20, plume 20 bottoms are that a round table-like base 30(is referring to Fig. 4), plume 20 external peripheral surfaces are socketed with a plurality of fin that are parallel to each other 10.The quantity of fin 10 and size can suitably increase and decrease according to watt level.

As shown in Figures 2 and 3, the interarea of fin 10 is four jiaos of shapes with essentially rectangular of chamfering, its upper punch is pressed with the rectangle heat conduction window 11 of a plurality of marshallings, the center of fin 10 stamps out a trepanning 12, trepanning 12 edges form and fly along 14, fly the firm socket that not only is conducive to fin 10 and plume 20 along 14, also helping increases plume 20 to the heat-conducting area of fin 10.Heat conduction window 11 a wherein opposite side punching press formation becomes 2 radiating fins 13 of an angle of 90 degrees with plane, fin 10 place; The height of radiating fin 13 is preferably 2/5ths of the heat conduction window 11 another side length of sides, so namely is conducive to one time punching moldedly, also is conducive to form suitable air flow passage.Fin 10 also has the flanging 15 of two symmetries, is used for neatly locating under the cooperation of frock when fin 10 is assembled to plume.

As Fig. 2, Fig. 3 and shown in Figure 4, a plurality of heat conduction windows 11 on each fin 10 on horizontal and vertical closely mutually alignment arrange, form the neat row and column that is parallel to fin 10 adjacent both sides respectively, a plurality of fin 10 are closely adjacent, under the effect of radiating fin 13, form a plurality of linear air flow passage 50 perpendicular to plume 20 axis; For a plurality of fin 10 on the radiator 1, also alignment mutually of the heat conduction window 11 of corresponding position on every adjacent two fin 10, thus form the linear air flow passage 40 that is parallel to plume 20 axis.Therefore, no matter be on the parallel direction that also is perpendicular to plume 20 axis, can both form the structure of a plurality of similar chimneys, utilize stack effect, performance of ventilating increases, and cross-ventilation is more smooth and easy, thereby guarantee that radiator 1 when 360 degree angular ranges use, can keep heat dispersion preferably.

In other embodiments, fin also can be circular or other shapes, and at this moment, the heat conduction window on each fin preferably also is proper alignment on horizontal and vertical, form orthogonal row and column, in order to form the linear air flow passage perpendicular to the plume axis; If the also alignment mutually of heat conduction window in per two adjacent fin corresponding positions also is conducive to form the linear pattern air flow passage that is parallel to the plume axis.

Certainly, heat conduction window arrangement mode in the various embodiments described above can not be that the linear pattern that is horizontal and vertical is arranged, arrange but be other modes, annular array for example, diagonal angle line style arrangement etc., in a word, which kind of arrangement mode the heat conduction window adopts, and can carry out freely selecting according to factors such as using needs and processing conditions; The shape of heat conduction window also can not be rectangle but circular or other shapes.And the quantity of radiating fin also can be one, and shape also can change according to the different of heat conduction window shape with the position, but should be in the marginal position of heat conduction window.In addition, the shape of plume can not be cylindrical also, also can adopt cylindrical shape, cuboid, hollow, rectangular body etc.
