[0014] figure 1 Shown is a schematic flow chart of the manufacturing method of the airtight cavity structure of the present invention, which includes the following main steps: making a core mold with a porous structure → pre-treatment for the first electroforming → forming a capillary structure by the first electroforming → before the second electroforming Processing → secondary electroforming to form outer shell → electroforming post-processing → finished product.
[0015] For brevity and convenience of description, the following is Figure 4 versus Figure 5 The airtight cavity structure 30 shown in is representative to illustrate the above-mentioned manufacturing method. Figure 4 versus Figure 5 It is a schematic diagram of the air-tight cavity structure 30 before being filled with working liquid and without being sealed. The air-tight cavity structure 30 includes a shell 31, a cavity 32 is formed in the shell 31, a porous capillary structure 33 is arranged on the entire inne...
