Promote heat directional transmission's phase transition base plate

The utility model relates to a promote heat directional transmission's phase transition base plate, include: two micro -structure boards, packing ring and liquid phases matter of exchanging work, theunilateral surface of micro -structure board has a two -layer capillary structure, and surface that two blocks of micro -structure boards have capillary structure is relative and put, in the middle ofthe packing ring is located two blocks of micro -structure boards, and the connection of closely laminating of two blocks of micro -structure boards and packing ring, inside vacuole formation, the cavity intussuseption is filled with the liquid phases matter of exchanging work, still including being used for toward the interior filling liquid attitude phase -change working medium's of cavity notes liquid pipe. First layer capillary structure is little slot, and second floor capillary structure is the slightly -inclined hole, and the adjacent setting of two -layer capillary structure and the size order of magnitude are
