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.
