Embodiment 1
[0025] see figure 1 The LED lateral fluid cooling COB light source described in the embodiment of the present invention includes: a microarray heat pipe plate 1, a silver plating layer 2, a circuit layer 3, an insulating paint layer 4, a chip 6, a silica gel 7, and a copper plating layer 8. Array heat pipe plate 1, copper plating layer 8, silver plating layer 2, circuit layer 3, and insulating varnish layer 4 are compounded sequentially. The outer surface of the chip 6 is sealed and fixed with silica gel 7, and the chip 6 is closely attached to the silver plating layer 2 and welded. Fixed, the shape of the microarray heat pipe plate 1 is a thin plate. The microarray heat pipe plate 1 is integrally formed by cold drawing of aluminum material. Inside the microarray heat pipe plate 1, a plurality of independently operating micro-array channels 11 are arranged side by side. The micro-array channel 11 is filled with The working fluid is filled with working fluid in the micro-array ...
