Abstract
The utility model provides a heat sink structure for LED industrial and mine lamps, which comprises an annular heat sink body, and the center of the body is provided with a central heat pipe hole for mounting a heat pipe; fins are evenly distributed in the form of a sunflower on the periphery of the body; and a plurality of cavities are evenly distributed between the central heat pipe hole of the body and the fins. The heat sink structure has the advantages that: since the technical scheme is adopted, the heat-dissipating efficiency is high, and meanwhile, since the separate cavities are formed in the heat sink, water can be conveniently prevent.
Description
Technical field
The utility model belongs to LED lamp technical field, especially relates to a kind of radiator structure of LED bulkhead lamp capable.
Background technology
The LED bulkhead lamp capable is to adopt the ultra-bright LED white light as illuminating source, shell adopts the metal materials such as aluminium alloy, outer cover has adopted the materials such as high efficiency lens, heat radiation is adopted copper sheet heat conduction to add the aluminum alloy bar heat radiation and is circulated in conjunction with natural air, LED bulkhead lamp capable power is only 20% of sodium vapor lamp, meet especially the green low-carbon requirement that country proposes, be applicable to the inflammable and explosive places such as factory and enterprise, industrial and mining enterprises, oil, chemical industry, smelting and do light projector or floodlighting.
In prior art, various radiator structures are arranged, but its existence is not easy to the defective of waterproof.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of radiator structure of LED bulkhead lamp capable.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of radiator structure of LED bulkhead lamp capable comprises the circular radiating body, and the center of described body is provided with the heat pipe mesopore, is used for installing heat pipe; The uniform radiating fin of body outer rim is the heronsbill type; Uniform some cavitys between the heat pipe mesopore of described body and radiating fin.
Further, described body and radiating fin are formed in one.
Further, uniform several special-shaped fins in described radiating fin.
Further, a kind of being shaped as in described special-shaped fin, the middle part of two fins is arc, the bottom is integrated; The middle part that is shaped as fin of another kind of special-shaped fin respectively is provided with a projection to both sides.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, radiating efficiency is high, forms independently cavity in the middle of making simultaneously radiator, is convenient to waterproof.

The specific embodiment
As shown in Figure 1, the radiator structure of a kind of LED bulkhead lamp capable of the utility model comprises circular radiating body 1, and the center of described body 1 is provided with heat pipe mesopore 2, is used for installing heat pipe; The body 1 uniform radiating fin of outer rim is the heronsbill type; Uniform some cavitys 3 between the heat pipe mesopore 2 of described body 1 and radiating fin; Described body 1 is formed in one with radiating fin; Uniform several special-shaped fins 4 in described radiating fin, a kind of being shaped as in described special-shaped fin 4, the middle part of two fins is arc, the bottom is integrated; The middle part that is shaped as fin of another kind of special-shaped fin respectively is provided with a projection to both sides.
The course of work of this example: the power source cavity of body 1 upper end connection LED bulkhead lamp capable, the bottom connects the LED installing plate, heat-conductive thermo tube is arranged in heat pipe mesopore 2, the heat that LED produces is transmitted on radiator body 1 by heat-conductive thermo tube fast, reduce the LED central temperature, form airtight cavity, dustproof and waterproof between cavity 3 and power source cavity.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
