Abstract
The utility model relates to a copper and aluminum composite type LED lamp radiator. The copper and aluminum composite type LED lamp radiator comprises an aluminum radiator body. A heat conducting copper piece is embedded into the heat conducting face of the aluminum radiator body through forging and pressing, and the outer surface of the heat conducting copper piece and the heat conducting face of the aluminum radiator body are kept smooth. The good heat conducting capacity of copper, the good heat dissipation performance of aluminum and other characteristics are combined, heat is rapidly transmitted to the aluminum radiator body through the heat conducting capacity of copper and is then rapidly dissipated due to the good heat dissipation performance of aluminum, and therefore the copper and aluminum composite type LED lamp radiator has the advantages of being good in heat dissipation effect, high in safety, long in service life, simple in structure, convenient to manufacture and the like.
Description
Technical field
The utility model relates to heat sink technology field, relates in particular to a kind of copper aluminium combined type LED lamp radiator.
Background technology
Along with LED power improves constantly, particularly the LED lamp of high-power integrated packaging COB light source, requires more and more higher to the heat radiation of radiator.In general, increasing heat radiation area can increase the radiating effect of radiator, but also increased volume and the cost of radiator simultaneously, because LED light fixture all trends towards miniaturization development now, therefore can change an angle and consider its heat dissipation problem from the selection aspect of radiator.
At present, LED lamp radiator mainly has die casting aluminium radiator, aluminium extrusion moulding radiator and forging forming radiator etc., its selection is the aluminium that heat dispersion is good, but the heat conductivility of aluminium is general, can not timely and effectively the heat of COB light source in light fixture be conducted and be come rapidly, thereby finally have influence on the radiating effect of radiator, reduce the service life of LED lamp etc.
Utility model content
The purpose of this utility model is to overcome the defect of prior art, provides a kind of also Quick diffusing of can rapidly heat conduction being come to go out, and copper aluminium combined type LED lamp radiator simple in structure, easy to make.
The purpose of this utility model is achieved through the following technical solutions:
A copper aluminium combined type LED lamp radiator, comprises Aluminium Radiator main body, on the thermal conductive surface of described Aluminium Radiator main body, by forging and stamping, has embedded a heat conduction copper sheet, and the thermal conductive surface of the outer surface of heat conduction copper sheet and Aluminium Radiator main body keeps smooth.
Further, be provided with and the corresponding pre-indent of heat conduction copper sheet shape on the thermal conductive surface of described Aluminium Radiator main body, described heat conduction copper sheet embeds in this pre-indent by forging and stamping.
Further, the notch of described pre-indent is less than the size of heat conduction copper sheet, so that between the two be interference fit.
Further, described heat conduction copper sheet is colored shape, circle or square.
Further, the thickness of described heat conduction copper sheet is 0.5mm～5mm.
Further, described Aluminium Radiator main body has a substrate, and a described substrate wherein end face is provided with plural radiating fin, and described substrate other end is thermal conductive surface.
The beneficial effects of the utility model are:
The feature such as capacity of heat transmission heat dispersion good, aluminium in conjunction with copper is strong, adopt Aluminium Radiator main body to inlay the composite construction of heat conduction copper sheet in radiator, can utilize like this capacity of heat transmission of copper heat to be conducted in Aluminium Radiator main body rapidly, by the heat dissipation characteristics of aluminium, fast dissipation of heat is gone out again, thereby more effectively the heat of COB light source in light fixture is conducted to good heat dissipation effect, safe, long product lifecycle, and simple in structure, easy to make.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 5, a kind of copper aluminium combined type LED lamp radiator providing according to the utility model, comprise Aluminium Radiator main body 1, Aluminium Radiator main body 1 has a substrate 10, and substrate 10 fronts are provided with plural radiating fin 11, and substrate 10 back sides are thermal conductive surface 12, on thermal conductive surface 12, be provided with pre-indent 121, in pre-indent 121, by forging and stamping, has embedded a heat conduction copper sheet 2, shape and the heat conduction copper sheet 2 of indent 121 match in advance, and the outer surface of heat conduction copper sheet 2 and thermal conductive surface 12 maintenances smooth.
For strengthening adhesion, guarantee that heat conduction copper sheet 2 and Aluminium Radiator main body 1 are combined with each other reliably, the notch of described pre-indent 121 is less than the size of heat conduction copper sheet, so that between the two be interference fit.
As shown in Figures 2 to 4, the shape of heat conduction copper sheet 2 can be flower shape, circle, square or other various shapes, and the thickness of heat conduction copper sheet 2 is 0.5mm～5mm.
As described above, it is only preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented with this, the simple equivalence of generally doing according to the utility model claim and utility model description changes and modifies, and all still belongs in the scope that the utility model patent contains.
