Embodiment Construction

[0011] Hereinafter, the present invention will be further described through embodiments in combination with the drawings.

[0012] Such as figure 1 As shown, a new type of high-power LED heat sink includes a substrate (1), a finned heat sink (2), a micro pump (3), a fan (5) and an infusion tube (4). The substrate (1) is two The end is provided with an inlet and outlet for communicating with the infusion tube (4), the infusion tube (4) is in communication with the micro pump (3) and the finned radiator (2), and the infusion tube (4) is equipped with There is a cooling liquid, the micro pump (3) provides power to the cooling liquid to form a circulation loop, and the fan (5) is arranged under the fin radiator (2).

[0013] The substrate (1) is filled with a porous medium (8).

[0014] The position of the fin radiator (2) is not limited, and can be placed at a required position according to actual conditions.

[0015] The LED chip (9) is fixed on the substrate (1). When the high-power ...

Abstract

The invention relates to a novel high-power LED radiating device which comprises a base plate, a finned radiator, a miniature pump, a fan and a liquid delivery tube. An inlet and an outlet which are used for being communicated with the liquid delivery tube are formed in two ends of the base plate, the liquid delivery tube is communicated with the miniature pump and the finned radiator and is filled with cooling liquid, the miniature pump provides power for the cooling liquid to form a circulating circuit, the fan is arranged below the finned radiator, the base plate is filled with porous media, and the finned radiator is free of location limitation and can be placed at a required position according to actual conditions. The novel high-power LED radiating device has the advantages that LED heat can be transferred by the aid of characteristics of large contact area and high heat transfer rate of the porous media, the miniature pump provides the power for the cooling liquid to form the circulating circuit, the flow rate of the liquid can be changed, and accordingly the LED heat can be radiated under the control.

Description

Technical field [0001] The invention relates to an LED heat dissipation device, in particular to a new type of high-power LED heat dissipation device. Background technique [0002] Compared with traditional light sources, LED lighting has the advantages of energy saving, environmental protection and long life. Today, with the theme of energy saving, emission reduction, and environmental protection, LED lighting has become a new economic growth point and has attracted great attention. With the development of LEDs and the continuous improvement of people's requirements for luminous brightness, power and reliability, the demand for high-power LEDs continues to grow. However, the development of high-power LEDs is still in its infancy and there are many problems. In the working process of high-power LED, in addition to light emission, a large amount of heat is generated at the same time, and the temperature of the LED chip directly affects the life of the lamp. Therefore, high-powe...
