Common Cooling Techniques in Thermal Management
Removing heat from an electronic device can be achieved from one or more external surfaces, or through internal means. In addition, several modes of heat transfer can be capitalized on to cool an electronic device that is warmer than desired.
Heat Sink Selection Methodology in Electronics Cooling
To select the best heat sink for your application, it is important to understand the basic heat transfer mechanism used to remove heat flux. The heat transfer theory helps explain practical aspects of how heat sinks work. It also helps to clear up common misconceptions and design mistakes.
Heat Transfer Coefficient in High Altitudes
At higher elevations, the pressure and density are low. Fans are basically constant volume sources, implying that the mass flow rate, which is the product of volumetric flow rate and density, reduces at elevations. With the significant reduction of mass flow, a designer must consider different possibilities.
TECs and Micro TECs for Spot Cooling Electronics
The microprocessor evolution should make the jobs of system thermal engineers easier. However the complexity of the processor brings a unique set of cooling challenges. Spot cooling with TECs offers several advantages which must be carefully studied to ensure a successful implementation.
