Abstract

The utility model discloses a combined LED radiator. The LED radiator comprises an aluminum alloy member body, wherein the aluminum alloy member body is equipped with a base plate; the circumference of the base plate extends upwards to compose a tapered hollow housing, an inward-recessed shallow slot is opened in the base plate, and a copper sheet member which closely fits with the shallow slot is inlaid in the shallow slot. In the utility model, the good heat conductive capability of copper is combined with the strong heat radiation capability of aluminum, wherein a copper bottom is inlaid in the aluminum radiator, so that heat is transmitted to the aluminum radiator by utilizing the heat conductive capability of copper, and the heat is rapidly radiated through the heat radiation feature of aluminum; thus, the heat of chips can be more effectively conducted and radiated, the heat radiation effects are good, and the safety level is high.

Description

Combined type LED radiator

Technical field

The utility model relates to the heat sink technology field, is specifically related to a kind of combined type LED radiator.

Background technology

Along with the development of solid state lighting, the LED illumination that integrates multiple advantage just progressively strides forward to third generation new type light source at present.LED changed the incandescent lamp tungsten filament luminous with the luminous principle of fluorescent lamp tricolor powder, utilize electroluminescence, have that light efficiency height, radiationless, life-span are long, an advantage of low-power consumption and environmental protection.Along with the progress of science and technology, aluminum products LED lamp is developed fast, and the heat that is produced is not well improved; Therefore; All be provided with radiator at these energy-saving LED lamps, common radiator all is that aluminum alloy materials is made, and through the fin on the radiator heat is distributed.But,, still can not effectively the heat that is produced be distributed rapidly owing to receive the restriction of material cost.

The utility model content

The purpose of the utility model is exactly the defective to prior art, and a kind of combined type LED radiator is provided, and its radiating effect is better than the radiator that adopts homogenous material to make.

To achieve these goals; The technical scheme of the utility model is: a kind of combined type LED radiator is provided; Comprise the aluminium alloy element body, said aluminium alloy element body has a base plate, and the periphery of base plate extends upward and constitutes a tapered hollow housing; On institute's base plate, offer the shallow slot that inwardly concaves, be inlaid with the copper member of a slice and said shallow slot tight connecting at said shallow slot.

In above-mentioned combined type LED radiator, the centre of said hollow housing is a hollow cylinder with upper shed, and the outside of hollow cylinder is attached with one-body molded, and is the multi-disc heat radiation thin slice that grid type is interspersed.

In above-mentioned combined type LED radiator, the rounded structure of the said shallow slot that inwardly concaves, the edge of said copper member and the profile phase of said shallow slot coincide.

In above-mentioned combined type LED radiator, also offer a seam groove that is used to install chip on the said base plate.

The utility model beneficial effect is: the combined type LED radiator that the utility model provides; It includes the radiator body that adopts aluminium to make, adopting the heat absorption copper sheet with the contacted position of heater, good in conjunction with the capacity of heat transmission of copper, characteristics such as the heat-sinking capability of aluminium is strong; At the bottom of radiator adopted aluminium radiator edge copper; The capacity of heat transmission that can utilize copper like this to aluminium radiator, distributes heat transferred at the heat dissipation characteristics through aluminium fast with heat, thereby more effectively the heat of chip is conducted; Good heat dissipation effect, safe.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described, like Fig. 1～shown in Figure 3,

A kind of combined type LED radiator is provided; Be provided with an aluminium member bodies 1; Said aluminium member bodies 1 has a base plate 103; The periphery of base plate 103 extends upward and constitutes a tapered hollow housing, on institute's base plate 103, offers the shallow slot 102 that inwardly concaves, is inlaid with the copper member 2 of a slice and said shallow slot 102 tight connectings at said shallow slot 102.

In above-mentioned combined type LED radiator, the centre of said hollow housing is a hollow cylinder 101 with upper shed, and the outside of hollow cylinder 101 is attached with one-body molded, and is the multi-disc heat radiation thin slice 104 that grid type is interspersed.

At the above-mentioned combined type LED radiator of stating, the said shallow slot that inwardly concaves 102 rounded structures, the edge of said copper member 2 and the profile phase of said shallow slot coincide.

In above-mentioned combined type LED radiator, on said base plate 103, also offer a seam groove 105 that is used to install luminescence chip.

Tool and Die Technology capable of using is carried out shut up formula fit with radiator body and copper sheet and is inlayed, and reliability is high.
