Advanced microprocessor design creates more power on smaller processor sizes and requires therefore more intelligent cooling solutions as before.
Traditionally processors have been cooled by fan/heat sink combinations.
Due to height reductions and noise restrictions computer manufactures are looking for new solutions to get the maximum performance from the processor.
One of these solutions is Heatpipe cooling.
Processor Heatpipes consists generally of
- a heat spreader block to pick up the heat from the processor
- the Heatpipe itself to transfer the heat
- a fin area on which to dissipate the heat to ambient
The heat spreader block, fitted with one or more Heatpipes, transfers the generated heat to an area where the heat can be dissipated to ambient.
This could be another heat spreader block coupled to a metal housing, or stacked fins for natural convection, or stacked fins with a fan for forced convection.
Main applications for such Heatpipe Cooling is Laptop-, Desktop Computer- and Server Cooling.
