Patent ID: 7672129

Claim:
A cooling system for a heat producing component, comprising: a base comprising a plurality of microchannel cells, at least two of the cells having one or more microchannel passages therein, the base being configured to couple to an electronic device, wherein the plurality of microchannel cells is arranged in an N-by-M array such that temperatures are controllable in two dimensions on the heat producing component; and at least one magnetohydrodynamic pump configured to provision fluid to at least one of the microchannel passages, wherein the at least one magnetohydrodynamic pump comprises one or more pairs of magnetohydrodynamic pumps, wherein each of the one or more pairs of magnetohydrodynamic pumps is arranged to pump fluid in series and configured to pump fluid in one of the microchannel cells, wherein at least one of the one or more pairs of magnetohydrodynamic pumps comprises a first magnetohydrodynamic pump and a second magnetohydrodynamic pump in a common enclosure, wherein the first magnetohydrodynamic pump is configured to pump fluid through the common enclosure in a first direction and the second magnetohydrodynamic pump is configured to pump fluid from the first magnetohydrodynamic pump through the common enclosure in a direction opposite to the first direction.
