Abstract

See full text

Apparatus and method are provided for cooling an electronic component. The apparatus includes a refrigerant evaporator in thermal communication with a component(s) to be cooled, and a refrigerant loop coupled in fluid communication with the evaporator for facilitating flow of refrigerant through the evaporator. The apparatus further includes a compressor in fluid communication with a refrigerant loop, an air-cooled heat sink coupled to the refrigerant evaporator, for providing backup cooling to the electronic component in a backup, air cooling mode, and a controllable refrigerant heater coupled to the heat sink. The refrigerant heater is in thermal communication across the heat sink with refrigerant passing through the refrigerant evaporator, and is controlled in a primary, refrigeration cooling mode to apply an auxiliary heat load to refrigerant passing through the refrigerant evaporator to ensure that refrigerant in the refrigerant loop entering the compressor is in a superheated thermodynamic state.
