Patent ID: 7870893

Claim:
A cooling device, comprising: a base configured to couple with an electronic device, the base comprising at least one cell; at least one pipe coupled to the base, the at least one pipe comprising a first passage in fluid communication with the at least one cell and a second passage in fluid communication with the at least one cell, the first passage being configured to carry fluid toward the at least one cell and the second passage being configured to carry fluid away from the at least one cell; a magnetohydrodynamic pump system coupled to the at least one pipe configured to circulate fluid within the passages and the at least one cell, wherein the magnetohydrodynamic pump system comprises at least one pump comprising: an electrically non-conductive outer tube segment; an electrically non-conductive inner tube segment at least partially disposed in the outer tube, the inner tube comprising an inner passage, at least a portion of the space between the inner tube and the outer tube forming an outer passage; a plurality of conductors, each conductor passing through a wall of the outer tube and a wall of the inner tube; an insulator coupled to each of the plurality of conductors, each insulator configured to electrically insulate the respective conductor from fluid in the outer passage; and one or more magnets configured to produce a magnetic field in the inner passage; and an orifice configured to emit a jet of fluid from the first passage into the at least one cell when the fluid is circulated by the magnetohydrodynamic pump system.
