Liquid-circulation-based LED array cooling system

Abstract

The invention discloses a liquid-circulation-based LED array cooling system which comprises an LED array composed of a plurality of LEDs. A cooling mechanism of each LED is in a cavity shape. Each cavity shaped cooling mechanism is provided with a liquid inlet end and a liquid outlet end. The liquid inlet ends and the liquid outlet ends of each two adjacent LEDs are connected through liquid pipelines. The liquid inlet end and the liquid outlet end at two ends of the LED array are connected with a liquid circulation drive device through pipelines. Heat is transferred between the whole LED array and liquid inside a drive liquid pipeline of the liquid circulation drive device. The liquid circulation drive device is provided with a heat exchanger used to guide out liquid carrying LED heat. The manner of liquid circulation cooling is adopted, the LED array composed of the LED lamps is serially connected with the pipelines which are used to circulate for cooling, and accordingly cooling cost for each LED is reduced, and the circulating liquid is capable of transferring heat quickly.

Problems solved by technology

The core light-emitting part of the LED lamp is the LED wick. The LED wick will generate a lot of heat during work. Due to the small size of the LED wick, no matter what type of LED lamp, it is necessary to achieve rapid heat conduction, which also affects the life of the LED lamp. And one of the key factors of lighting quality, and because of this, the heat dissipation structure of the existing LED lamps is very large in volume. Considering the overall appearance and volume requirements of the lamps, the heat dissipation structure of the LED lamp is relatively Due to the large volume occupancy rate of the LED wick

[0004] On the other hand, the existing single LED lamps all use independent heat dissipation mechanisms. In more applications, it is usually necessary to install multiple LED lamps, which undoubtedly increases the overall cost of lamps and installation costs, especially in indoor lighting applications. , the installation of LED arrays composed of multiple existing heat dissipation mechanisms and LED lamps with LED wicks independently set, the cost disadvantages are particularly prominent
