Passive liquid phase-change cooling system with no fan, called a heat pipe. At the end of the heat pipe located near the element to be cooled, the liquid fluid vaporizes by absorbing thermal energy emitted by the LEDs. Steam then circulates in the heat pipe to the other end located at a heat sink where it condenses to return to a liquid state. Condensation permits the transfer of thermal energy. This system allows for intensive use in extreme conditions. It is indispensable in places where absolute silence is required.
