Embodiment 1

[0025] A cooling device, the structure of which is as follows figure 1 , including a radiator 1 and an air passage 2 installed on one side of the radiator 1 for air convection and heat dissipation.

[0026] Radiator 1 is made of aluminum, and its structure is as follows: figure 2 As shown, it consists of a cylindrical heat dissipation base 11 and heat dissipation fins 12 arranged around the heat dissipation base 11 .

[0027] The air channel 2 is set in two, made of heat insulating material, and is a cylindrical structure with a central through hole, symmetrically fixedly connected to one side end surface of the radiator 1, and a gap gap. The through hole of the air channel 2 is perpendicular to the end surface of the radiator 1 .

Embodiment 2

[0029] An LED lamp is composed of three parts: the light source part, the cooling device and the power supply part. Its appearance assembly diagram is as follows: image 3 As shown, the internal structure is as Figure 4 , Figure 5 .

[0030] The heat sink adopts the heat sink described in Embodiment 1.

[0031] Light source parts such as Figure 5 , consists of a boss 31, an LED chip 32, a reflector 33, a silicone pad 34, a light-transmitting mirror 35 and a snap ring 36 in turn. The boss 31 is made of the same aluminum material as the heat sink 1 , and is embedded on the heat dissipation base 11 on one end surface of the heat sink 1 . The reflector 33 is mounted on the boss 31 , and an LED chip 32 is embedded at the bottom of the reflector 33 . The light-transmitting mirror 35 is fixedly mounted on the front end of the reflector 33 with a snap ring 36 , and a silicone gasket 34 is used for sealing between the reflector 33 and the light-transmitting mirror 35 .

Abstract

The invention provides a heat sink. The heat sink comprises a heat-dissipating body consisting of a column-shaped heat-dissipating base body and heat-dissipating fins arranged around the heat-dissipating base body, and an air channel provided with a central through hole, wherein the air channel is fixedly connected to the end surface of one side of the heat-dissipating body, and the through hole is vertical to the end surface of the heat-dissipating body. A light source part and a power supply part of the LED light using the heat sink are arranged on the end surfaces of both sides of the heat sink respectively. Because the air channel structure used for cross-ventilation and heat dissipation is adopted in the heat sink, the heat-dissipating efficiency of the heat-dissipating body is obviously improved. When the heat sink is used on the LED light, the heat-dissipating problem of the LED light is better improved, and the practicability of the LED light is also improved.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device which utilizes air convection to improve the heat dissipation efficiency of the heat dissipation device. The invention also relates to an LED lamp using the cooling device. Background technique [0002] With the enhancement of people's awareness of energy conservation and environmental protection, countries are vigorously developing renewable clean energy such as solar energy and wind energy. In the field of lighting, various new light sources are constantly being introduced and widely used. Among them, LED (Light Emitting Diode) is more and more widely used in the lighting field due to its advantages of low energy consumption, high light efficiency, long life and good color rendering. [0003] It is an ideal choice to use high-power LEDs as lighting devices. For LEDs, increasing the input power increases the brightness proportionally. The efficiency of t...
