Abstract

The utility model provides a heat sink for LED lamp, include: basement with set up a plurality of fins in the basement, basement and fin are piled up by the flat layer of the heat conductor range of multilayer adoption rule and are formed, fin evenly distributed is in the basement. The utility model discloses utilize regular graininess aluminium alloy material, pursue to pursue and pile up the radiator appearance that becomes to need with vibration material disk's mode, have sufficient convection current and radiation heat radiating area when having sufficient heat conduction area, effectual volume and the weight that has reduced the product, the cost is reduced simultaneously.

Description

A kind of LED lamp heat abstractor

Technical field

This utility model relates to a kind of heat abstractor, is specifically related to a kind of LED lamp heat abstractor.

Background technology

Light fixture is indispensable article in people's daily life in the present age, along with constantly carrying of people's living standard Height, the effect of light fixture is the most not only limited as illuminating effect, and LED is as a kind of light source quilt energy-conservation, efficient It is widely used in various field, but LED self operationally produced heat is to affect LED to use The key factor in life-span, therefore, general LED lamp all can be by a heat radiation being arranged on LED back Plate dispels the heat.

Existing LED radiator, based on fin type structure, uses the method manufactures such as aluminium extruded type, die casting, punching press, Often it is difficult to balance between heat-conducting area and convection current, heat loss through radiation area, causes heatsink weight, volume The hugest, cost is the highest.

Utility model content

For the problem overcoming above-mentioned prior art to exist, this utility model provides a kind of LED lamp heat radiation dress Put.

The technical solution of the utility model is: a kind of LED lamp heat abstractor, including a: substrate with set Put the flat board of the heat carrier arrangement being used rule at suprabasil some fins, described substrate and fin by multilamellar Layer stack is long-pending to be formed, and described fin is uniformly distributed in substrate.

Further, described heat carrier is heat conduction ball, uses spot welding mode to connect between described heat conduction ball.

Further, described heat conduction ball is the graininess spheroid that aluminum alloy materials makes.

The beneficial effects of the utility model are:

This utility model utilizes rule particle shape aluminum alloy materials, by the mode of spot welding (electric resistance welding), by By to increase the radiator profile being piled into needs in the way of material manufacture, having the same of enough heat-conducting areas Convection current that Shi Yongyou is enough and heat loss through radiation area, be effectively reduced volume and the weight of product, drop simultaneously Low cost.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in detail.

Seeing Fig. 1 to Fig. 4, wherein Fig. 1 is a kind of LED lamp construction for heat radiating device that the utility model proposes Front view；Fig. 2 is a kind of LED lamp construction for heat radiating device upward view that the utility model proposes；Fig. 3 is A kind of LED lamp construction for heat radiating device right view that the utility model proposes；Fig. 4 is for the utility model proposes A kind of LED lamp construction for heat radiating device axonometric chart.

As shown in Figures 1 to 4, a kind of LED lamp heat abstractor, including a: substrate 1 be arranged on Suprabasil some fins 2, described substrate 1 and fin 2 are used the flat board of the heat carrier arrangement of rule by multilamellar Layer stack is long-pending to be formed, and described fin 2 is uniformly distributed in substrate 1.

This utility model utilizes rule particle shape aluminum alloy materials, by the mode of spot welding (electric resistance welding), by By to increase the radiator profile being piled into needs in the way of material manufacture, owing to using the mode of spot welding by granule The heat carrier of shape connects, at spot welding outside be can convection current and heat loss through radiation area, therefore having enough Heat-conducting area while have enough convection current and heat loss through radiation area, be effectively reduced the volume of product With weight, reduce cost simultaneously.

Above this utility model is described in detail, but this utility model is not limited to above-mentioned embodiment, In the ken that those of ordinary skill in the art are possessed, it is also possible to without departing from this utility model objective On the premise of make a variety of changes.Many other can be made without departing from spirit and scope of the present utility model to change Become and remodeling.Should be appreciated that this utility model is not limited to specific embodiment, scope of the present utility model It is defined by the following claims.

Claims

1. a LED lamp heat abstractor, it is characterised in that including a: substrate and be arranged on base Some fins at the end, described substrate and fin are used the flat board layer stack of the heat carrier arrangement of rule by multilamellar Amassing and form, described fin is uniformly distributed in substrate.
