Abstract
Apparatuses, systems and methods for effective cooling of electronic devices are presented herein. More specifically, embodiments of the present invention comprise one or more heat pipes thermally coupled to electronic components and to a first heat sink and a second heat sink. The heat pipes are constructed to transfer heat generated at the one or more electronic components to the first heat sink and to the second heat sink. The first heat sink is operable to transfer heat energy to the ambient air using dissipation or advection. The second heat sink is able to transfer heat energy to the ambient air using dissipation. A controller is operable to switch between a passive mode of operation and an active mode of operation. The system can operate in a passive mode only in temperatures less than 25 degrees Celsius, can switch operation between a passive mode and an active mode without throttling in temperatures less than 60 degrees Celsius, can switch operation between a passive mode and an active mode in temperatures greater than 60 degrees Celsius while maintaining about 85% or greater maximum processing speed, and can operate in a passive only mode with minimal throttling.
