Example Embodiment
[0041] Example 1
[0042] As shown in the figure, the LED array device 100 includes a substrate 101, and a plurality of LED light emitting elements 102 are arrayed on the substrate 100; a lens 103 is installed on each LED light emitting element 102 to direct the light from the LED light emitting element.
[0043] A cooling device for LED array devices, comprising a plurality of tube-shaped evaporators 1, a condensation chamber 2 and a heat dissipation manifold 3. The condensation chamber 2 includes a cylindrical body 2.1 with an upper opening and a circular cover plate 2.2. 2.2 Screw fixed on the body 2.1. The bottom plate of the main body is provided with a plurality of mounting holes 2.3; the tube-shaped evaporator 1 is made of fast heat-conducting materials, such as copper, aluminum alloy, graphene, or other materials with high thermal conductivity. The tubular evaporator 1 is installed on the mounting hole 2.3 of the bottom plate of the condensing chamber 2; the tubular evapor...
Example Embodiment
[0053] Example 2
[0054] The tube-shaped evaporator 1 includes a tube body 1.1, the tube body 1.1 is closed at both ends, and a phase-changeable working medium is installed in the tube body 1.1; the condensation chamber 2 is equipped with heat-conducting oil, and the liquid surface of the heat-conducting oil contacts at least the condensation of the heat dissipation manifold 3. Section 3.1;
[0055] The other features are the same as the first embodiment. The phase change heat dissipation of embodiment 2 occurs at the upper end of the tube-shaped evaporator 1. The heat is transferred from the upper tube wall of the tube-shaped evaporator 1 to the heat transfer oil, the heat transfer oil is conducted to the heat dissipation manifold, and the heat transfer medium of the heat transfer oil is added in the middle , The phase change heat transfer increases the link, which reduces the phase change heat dissipation efficiency compared to Example 1.
