Abstract:
A micro cooling engine array system, which is fabricated by micro electro mechanical system technology, the micro cooling engine array system comprising:a matrix, being made of non-silicon materials, and having a first plate, a second plate and a laminated layer being sandwiched in and being bonded between the first plate and the second plate;a plurality of micro cooling engines enclosed and arrayed in the matrix, each of the micro cooling engines have a fluid for pumping heat out of a heat source which contacts to the first plate, each of the micro cooling engines further comprising:a heat-absorbing end having an expansion space and a first back space touching the first plate, a first flexible diaphragm bonded in the matrix separating the expansion space and the first back space for expanding the expansion space by deforming the first flexible diaphragm, thereby allowing the fluid to absorb heat form the heat source;a heat-ejecting end having a compression space and a second back space touching the second plate, a second flexible diaphragm bonded in the matrix separating the compression space and the second back space for compressing the compression space by deforming the second flexible diaphragm, thereby allowing the fluid to eject heat out of the micro cooling engine; anda regenerator interposed between the heat-absorbing end and the heat-ejecting end for allowing the fluid to flow therein.
