Abstract

The utility model discloses a radiator which comprises a radiator body with a central axle hole. The radiator body is made of aviation aluminum material. A hot air vent hole and a fixation hole are arranged in the radiator body. The hot air vent hole is in line with the central axle hole of the radiator body. The radiator body has two or more heat conduction sub-branches which stretch outwards along the axial direction. Each heat conduction sub-branch has two heat dissipation fins which stretch outwards along the axial direction, and a Y-shaped structure is formed by the two heat dissipation fins and each corresponded heat conduction sub-branch. The outer ends of the heat dissipation fins are provided with chamfers. The radiator provides a part of a light-emitting diode (LED). The radiator body contacts with the LED base plate at work directly and transmits the heat into the heat conduction sub-branches which can transmit the heat to the heat dissipation fins. The temperature reduced by the radiator is lower than that reduced by an ordinary radiator by 8 DEG C to 10 DEG C and the service life of an LED lamp is significantly prolonged.

Description

Radiator

Technical field

The utility model relates to a kind of LED accessory, particularly radiator.

Background technology

Along with the raising of the whole society to energy-saving and cost-reducing consciousness, the LED lamp is popularized as a kind of illuminations of low energy consumption gradually, and the heat that produces during its work is perplexing many light fixtures manufacturer always; Temperature one height shortens the life-span of LED light fixture greatly; Therefore must dispel the heat to the LED lamp, and radiator miscellaneous is of common occurrence, but all designs unreasonable; Though the radiator volume is big but radiating effect is bad; Light decay is serious, thereby has reduced the service life of LED, and be between 3.5 ~ 50,000 hours the service life of present LED lamp.

Summary of the invention

The purpose of the utility model is for the deficiency that solves above-mentioned prior art a kind of good heat dissipation effect to be provided, and improves the LED radiator in service life.

To achieve these goals; The radiator that the utility model designed comprise the heat radiator body of central shaft hole, and heat radiator body is made up of the aviation aluminum; On heat radiator body, be provided with hot gas through hole and fixing hole; The hot gas through hole is consistent with the central shaft hole of heat radiator body, and heat radiator body is outward extended with two and above heat conduction branch body vertically, and each heat conduction branch body has all outwards extended axially two radiating fins; And described two radiating fins constitute " Y " type structure with each corresponding heat conduction branch body, and the outer end of radiating fin is provided with chamfering.

The radiator that the utility model obtains; Through two radiating fins of design on heat conduction branch body; With heat radiator body directly and the LED substrate contacts, heat is passed to heat conduction branch body during work, pass to radiating fin by heat conduction branch body again; Realized that radiating effect is compared than common radiator and totally fallen 8 ~ 10 ℃, prolonged the life-span of light fixture LED greatly.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Embodiment 1:

In Fig. 1; Radiator comprises the heat radiator body 1 of central shaft hole; And heat radiator body 1 is made up of the aviation aluminum, on heat radiator body 1, is provided with hot gas through hole 3 and fixing hole 5, and hot gas through hole 3 is consistent with the central shaft hole of heat radiator body 1; And heat radiator body 1 is outward extended with two and above heat conduction branch body 4 vertically; Each heat conduction branch body 4 has all outwards extended axially two radiating fins 2, and these two radiating fins 2 and each corresponding heat conduction branch body 4 formation " Y " type structure, and the outer end of radiating fin 2 is provided with chamfering 6.

Concrete duty: the direct and LED substrate contacts of heat radiator body, heat is passed to heat conduction branch body, pass to radiating fin by heat conduction branch body again.
