Retractable heat exchanger

A heat dissipation assembly for an electronic device, comprising:

• a first heat spreader comprising a tab and positioned adjacent the processing device and in thermal communication with the processing device;
• and
• a second heat spreader comprising an alignment slot to receive the tab and positioned adjacent the first heat spreader and in thermal communication with the first heat spreader;
• wherein the second heat spreader is slideably engaged with the first heat spreader and is moveable between a first position in which the second heat spreader is disposed within the chassis and a second position in which at least a portion of the second heat spreader extends outside the chassis.

A controller for an electronic device comprising logic, at least partly including hardware logic, to:

• monitor a heat dissipation assembly for an electronic device, the heat dissipation assembly comprising:
• a first heat spreader comprising a tab and positioned adjacent the processing device and in thermal communication with the processing device;
• and
• a second heat spreader comprising an alignment slot to receive the tab and positioned adjacent the first heat spreader and in thermal communication with the first heat spreader;
• wherein the second heat spreader is slideably engaged with the first heat spreader and is moveable between a first position in which the second heat spreader is disposed within the chassis and a second position in which at least a portion of the second heat spreader extends outside the chassis;
• determine whether the second heat spreader is in the first position or the second position;
• and
• adjust an operating parameter of the processing device in response to a determination that the second heat spreader is in the first position or the second position.
