[0037] refer to Figure 2 to Figure 4 , the heat spreader of the present invention (thermal spreader) comprises: casing 1 defines steam chamber or vapor chamber (vapor chamber) 10 in it, fills into the evaporable working fluid after vacuumizing; And reticular intersecting capillary structure 2 is located in the steam chamber 10 of the housing.
[0038] The casing 1 can be made of materials such as metal with good thermal conductivity, and includes: a first casing cover 11 and a second casing cover 12 . The second casing 12 covers the first cover 11 and defines a steam chamber 10 between the first and second cover 11 , 12 .
[0039] Capillary thin layers 111, 121 can be connected to the inside of each of the shell covers 11, 12, and the capillary thin layers 111, 121 are selected from: metal (such as copper) mesh, sintered film, powder metallurgy thin layer, and other capillary thin layers . The thin capillary layers 111 , 121 can be welded, glued, and other connection metho...
