Patent ID: 8040145

Claim:
A temperature control device comprising: an interface surface configured to provide a thermal path to a device under test (“DUT”); a fluid-cooled heat sink structure configured to maintain a cross-flow of coolant in three dimensions for cooling said interface surface, where said fluid-cooled heat sink structure comprises: a first continuous fluid conduit for accommodating coolant flow in a first direction; a first three-dimensional microchannel structure located within said first continuous fluid conduit, said first microchannel structure being configured to direct coolant flow in three dimensions within said first continuous fluid conduit; a second continuous fluid conduit for accommodating coolant flow in a second direction different than said first direction; and a second three-dimensional microchannel structure located within said second continuous fluid conduit, said second microchannel structure being configured to direct coolant flow in three dimensions within said second continuous fluid conduit; and a heater assembly configured to heat said interface surface.
