Abstract:
1. A vapor chamber comprising: a planar lid with first support structures attached to and protruding from a first planar surface, with said first support structures spaced apart from each other by a first distance and arranged in parallel rows that are spaced apart by a second distance; first interlocking fixtures attached to said first support structures, the first interlocking fixtures extending from the first support structures to form first grooves which are dimensioned to receive second interlocking fixtures therein, the first interlocking fixtures and the first support structures forming first solid blocks; a planar base with second support structures attached to and protruding from a second planar surface, with the second support structures spaced apart by the first distance and arranged in parallel rows that are spaced apart by the second distance; the second interlocking fixtures attached to the second support structures, the second interlocking fixtures extending from the second support structures to form second grooves which are dimensioned to receive the first interlocking fixtures therein, the second interlocking fixtures and the second support structures forming second solid blocks; the first interlocking fixtures are dimensioned to fit tightly into the second grooves causing the first interlocking fixtures to be tightly maintained in the second grooves to prevent unwanted separation of the planar lid from the planar base; wherein said second distance is large enough to permit the parallel rows of the first support structures with the first interlocking fixtures to fit between the parallel rows of the second support structures with the second interlocking fixtures when the planar lid is moved toward the planar base; and wherein the first interlocking fixtures interlock with the second interlocking fixtures when the planar lid and the planar base are positioned to permit the first interlocking fixtures and the second interlocking fixtures to contact each other to lock the planar lid to the planar base to maintain the planar structure of the planar lid and the planar base by preventing their distortion from positive pressure on the first planar surface of the planar lid and on the second planar surface of the planar base of the vapor chamber caused when pressure from the vapor chamber exceeds atmospheric pressure.
