Abstract:
An apparatus for dissipating heat generated by an electronic device, comprising:a channel structure which is in thermal communication with an electronic device; a temperature sensor positioned in thermal communication with said channel structure; a circuit which generates a control signal if a temperature sensed by said temperature sensor is in a predetermined temperature range determined by thermal tolerance data for the electronic device; a baffle positionable, in response to said control signal, at a first position and a second position, wherein (i) said baffle is positioned to direct fluid flow in a first flow path defined by said channel structure when said baffle is in said first position, and (ii) said baffle is positioned to direct fluid flow in a second flow path when said baffle is in said second position; a first plurality of pumps configured to advance fluid through said first flow path; and a second plurality of pumps configured to advance fluid through said second flow path; wherein said first plurality of pumps are also configured to advance fluid through said second flow path when said baffle is in said second position.
