Heat sink

In particular, the present invention provides a heat dissipating device that utilizes a spiral airflow in a tube body to quickly and efficiently remove heat from the heat dissipating convex portion to greatly enhance the heat dissipating effect.

According to the continuous improvement of the industry, electronic components such as LEDs or CPUs tend to be light, thin and short. At the same time, under the demand of high power and high performance, the meaning is not only the improvement of power and performance, but also the improvement of performance. In the process, the relative heat of the electronic components is relatively increased, and the operating temperature of the electronic components is closely related to its reliability and service life. Therefore, how to effectively improve the heat dissipation capability of the electronic components and maintain the electronic components at normal operating temperatures becomes A key issue.

Taking the heat dissipation structure of the conventional illumination device as an example, the LED module of the illumination device is generally connected to the heat dissipation fin, and when the LED module emits light, the heat generated by the LED module is transmitted to the heat dissipation fin, and Cooling through the fins; however, the heat dissipation fins have a limited heat dissipation effect, which often makes the LED module unable to dissipate heat efficiently, especially for high-power lighting devices (such as outdoor lighting or collecting fish). For lamps and the like, the LED module of the high-power lighting device will generate more heat, and the way of dissipating the heat dissipation fins naturally will not be sufficient for the high-power LED module to dissipate heat quickly and effectively. The brightness and service life of the LED module.

In order to solve the above-mentioned drawbacks, the manufacturer has developed a method of forced convection to dissipate heat; as shown in Fig. 1, there is a conventional lighting device comprising a light source 10 and a heat sink 20; Have a first table a substrate 11 having a surface and a second surface, and a light emitting diode 12 disposed on the first surface of the substrate 11. The heat dissipating device 20 is disposed on the second surface of the substrate 11. The hollow casing 21 is provided with an air inlet 211 on the first side wall of the casing 21, an air outlet 212 on the second side wall, and a fan 22 at the air outlet 212, and the casing The heat dissipation fins 23 having the bottom plate 231 are disposed in the body 21, and the bottom plate 231 of the heat dissipation fins 23 is in contact with the second surface of the substrate 11. When the light-emitting diodes 12 of the light source 10 emit light, the light-emitting diodes The heat generated by the pole body 12 is transmitted to the bottom plate 231 of the heat dissipation fin 23, and the heat is dissipated in the casing 21 via the heat dissipation fin 23, and the hot air in the casing 21 is taken out by the fan 22. The air port 212 is exhausted, and the external cold air flows in from the air inlet 211 of the casing 21, so that the inside of the casing 21 and the outside air are forcibly convected, and the heat radiated from the heat radiating fins 23 is discharged to improve the heat dissipation effect; The use of forced convection can improve the heat dissipation effect, however, the light emission The heat of the body 12 is first transmitted to the bottom plate 231 of the heat dissipation fin 23, and then transmitted to the heat dissipation fin 23 by the bottom plate 231, so that the contact position of the bottom plate 231 with the light-emitting diode 12 has the highest heat, however, The airflow in the casing 21 can only accelerate the heat dissipation fins 23 to dissipate heat, and cannot directly remove the high heat from the bottom plate 231. Therefore, the forced convection heat dissipation method has better heat dissipation performance than the natural heat dissipation method. However, it is still insufficient for the light-emitting diode 12 to dissipate heat quickly and effectively, thereby affecting the brightness and the service life of the light-emitting diode 12.

In view of this, the inventor has been engaged in research and development and production experience of related industries for many years, and has conducted in-depth research on the problems currently faced. After long-term efforts and research, he has finally developed a cooling device and its application lighting equipment. In order to effectively improve the shortcomings of the prior art, this is the design tenet of the present invention.

And guiding the airflow in the air duct of the pipe body with the spiral blade of the flow guiding screw, so that the airflow flows in a spiral path in the air duct of the pipe body; thereby, the spiral airflow in the pipe body can be used quickly And effectively remove the heat of the heat dissipation convex portion, thereby achieving the practical purpose of greatly improving the heat dissipation effect.
