Abstract
An apparatus for cooling a computer'"'"'s microprocessor includes a thermal housing having a receiving aperture in alignment with the microprocessor. A thermal head is inserted into and guided by the receiving aperture such that a cooled surface of the thermal head will be in thermal contact with the microprocessor. The thermal head defines a flow channel for passage of a refrigerant fluid so as to cause cooling at the cooled surface. A clamping arrangement is attached to the mounting structure to maintain the thermal head in operative position. The apparatus further includes a refrigeration system in fluid communication with the flow channel of the thermal head to supply refrigerant fluid thereto.
