Abstract

The present invention provides a cooling system for a backlit device. The cooling system has a first heat collector that comprises a micro tube. The first heat collector is for maintaining contact with the backlit device. The cooling system also has a first radiator, a first pump, an interconnecting tubing, a fluid, and optionally a fan and/or a reservoir. The first radiator is for distributing and/or dispersing heat, the first pump is for driving a fluid flow, and the reservoir is for storing the fluid. The interconnect tubing is interposed between the first heat collector, the first radiator, and the first pump to form a closed cooling loop. Some embodiments further provide a method of cooling a backlit device by using such a cooling system.
