Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Referring to figs. 1 through Fig. 7, an embodiment of radiator of the present invention is proposed, this radiator is column, and the stacked assembling of fin 10 of being produced by some splits forms.This fin 10 is regular polygon setting, is provided with some braces 20 in the edge-perpendicular of fin 10, the aligned in position of the brace 20 on stacked fin 10, and brace 20 is for the connection between stacked fin 10.This brace 20 is for to extend to form downwards along the edge-perpendicular of fin 10, one-body molded with fin 10.Be provided with the notch 21 of upper end open on the top of brace 20, this notch 21, for to cut formation downwards from the edge of fin 10 and the connecting place of brace 20, is fillet trapezoid setting wide at the top and narrow at the bottom.Be provided with in the bottom of fillet and the inserted sheet 22 of notch 21 adaptations, the inserted sheet 22 of brace 20 bottoms on upper strata fin 10 inserts in the notch 21 on brace 20 tops on lower floor's fin 10.Limit, upper end at notch 21 is provided with outwardly tenon 23, is provided with and the tongue-and-groove 24 of tenon 23 adaptations on inserted sheet 22, and in the time that inserted sheet 22 inserts notch 21, tenon 23 buckles in tongue-and-groove 24.
When the stacked assembling of fin 10, inserted sheet on upper strata brace 20 22 is inserted in the socket on lower floor's brace 20, tenon 23 on socket buckles in the tongue-and-groove 24 on inserted sheet 22 simultaneously, adjacent fin 10 is interconnected, can complete the assembling of radiator, assembly operation is simple, can complete fast, and packaging efficiency is high.
Wherein, tenon 23 is downward and outward-dipping setting, thereby in the time that inserted sheet 22 inserts notch 21, the frictional force between tenon 23 and inserted sheet 22 is little, and inserted sheet 22 can slip over from tenon 23 preferably, is convenient to the connection of fin 10.
The limit, lower end of tongue-and-groove 24 is inwardly recessed, thereby in the time that inserted sheet 22 inserts socket, the limit, lower end of tongue-and-groove 24 is blocked in tenon 23 in tongue-and-groove 24, and tenon 23 is stuck in tongue-and-groove 24.
The stacked assembling of fin 10 that this radiator is produced by split forms, and monolithic fin 10 is thin and light, can alleviate weight and the consumptive material of radiator; And the production technology of monolithic fin 10 is relatively simple, the thickness of monolithic fin 10 is more easy to control and finishing also, can reduce the production and processing difficulty of radiator, enhances productivity.
The cost of monolithic fin 10 is than low many of the cost of existing radiator, and as fin 10 exists defect, when defective, its cost expending is low many of the radiator of entirety also, thereby can reduce costs.And radiator, in production or use procedure, as certain exists defect, only needs to change the fin 10 that has defect, without radiator integral is scrapped, thereby can reduce waste.
Because notch 21 is arranged on the top of brace 20, inserted sheet 22 is arranged on the bottom of brace 20, the inserted sheet 22 on upper strata brace 20 inserts the socket on lower floor's brace 20, after fin 10 is interconnected, upper strata fin 10 is supported on lower floor's fin 10 by brace 20, between the opposite face of upper strata fin 10 and lower floor's fin 10 every at regular intervals, make to form ventilation slot 30 between the opposite face of fin 10, be beneficial to ventilation and heat, can allow every fin 10 fully contact with air, improve radiating efficiency.
On fin 10, be provided with some air vents 12, air vent 12 is arranged in flower shape, aligns one by one in air vent 12 positions on adjacent fin 10, forms vented cavity.Vented cavity is crossing in length and breadth with ventilation slot 30, is interconnected, and realizes 360 ° of ventilation and heat of radiator, and heat radiation evenly, can be accelerated the integral heat sink effect of radiator.
Being provided with the short slot 11 of outer end opening at the edge of fin 10, aligns one by one in short slot 11 positions on adjacent fin 10, forms strip-shaped clamp groove.This short slot 11 is U-shaped groove or dovetail groove, and it is U-shaped draw-in groove or dove-tail form draw-in groove that the strip-shaped clamp groove forming is arranged in short slot 11 alignment.In strip-shaped clamp groove, be inserted with the connection strap 40 of an adaptation, on connection strap 40, be provided with the connecting hole 42 for being connected with LED light source plate.
As shown in Figure 1, this short slot 11 is U-shaped groove, and it is U-shaped draw-in groove that the strip-shaped clamp groove forming is arranged in short slot 11 alignment.Fin 10 is polygon, the radiator of fin 10 stacked formation is polyhedron, on each limit of fin 10, be provided with a short slot 11 and two braces 20, brace 20 is arranged on the dual-side of short slot 11, thereby, brace 20 and strip-shaped clamp groove arrange on each side of radiator, and strip-shaped clamp groove is placed between two row's braces 20.
Connection strap 40 is L-type, and its one end is vertically provided with flanging 41, and in the time that connection strap 40 inserts strip-shaped clamp groove, flanging 41 is overlapped on the outermost layer fin 10 of radiator one end, makes connection strap 40 fixing.When LED light source plate is installed, LED light source plate is posted on two row's braces 20 of radiator side, the connection strap 40 of the strip-shaped clamp groove in the middle of being placed in is relative with LED light source backboard face, on LED light source plate, be provided with the connecting hole corresponding with connecting hole 42 on connection strap 40, at LED light source plate and mounting screw in relative connecting hole on connection strap 40, LED light source plate can be fastened on radiator.Be connected with LED light source plate by connection strap 40, LED light source plate be arranged on the side of radiator, be convenient to the installation of LED light source plate.On fin 10, be also provided with some installing holes 13, be convenient to, in the end of radiator, LED light source plate is installed.The LED light source backboard face of installing and radiator laminating, large area contact, heat conduction is quick.This radiator can be used for high-power corn lamp, bulb lamp, bulkhead lamp capable etc., of many uses.
These are only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure transformation that utilizes description of the present invention and accompanying drawing content to do, or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
