Abstract
A coolant flow drive apparatus is provided for facilitating removal of heat from a cooling structure coupled to a heat generating electronics component. The coolant flow drive apparatus includes a turbine in fluid communication with a primary coolant flowing within a primary coolant flow loop, and a pump in fluid communication with a secondary coolant within a secondary coolant flow path. The secondary fluid flow path is separate from the primary coolant flow path. The flow drive apparatus further includes a magnetic coupling between the turbine and the pump, wherein the turbine drives the pump through the magnetic coupling to pump secondary coolant through the secondary coolant flow path.
