Over the past decade Aavid Thermalloy has pioneered heat pipe technology and its application, developing a high quality manufacturing process to ensure long life and reliability in its heat pipes. Andrea Sce, Aavid certified thermal systems design engineer, project leader at Aavid Thermalloy, tells us more
Heat pipes have many advantages and applications in thermal management. The availability of a wide range of heat pipes sizes and power-handling capabilities make them suitable for integration in heat sinks for 50W processors to multi kilowatt IGBTs. Heat pipes are great thermal energy transporters that use an evaporator and condenser in place of a solid conductor. While they do not dissipate heat themselves, heat pipes quickly move heat from one area of the heat pipe to another area especially when embedded in a base plate.
They can quickly move heat away from temperature sensitive devices to a place the heat may be dissipated. Heat pipes can also be used to increase fin efficiency by moving heat directly to the cooler top portion of fins. Many types of applications can benefit from heat pipes, from UPS to telecommunications to motor drives and controls to transportation to servers and computers.
As well as extending the thermal range of both natural and forced convection cooling, heat pipes reduce overall cost and weight without increasing the volume in a base plate and have no moving parts. Small-diameter heat pipe assemblies provide greater thermal efficiency whilst large diameter heat pipe assemblies transfer greater power loads.
Now Aavid Thermalloy has produced a white paper that explains the uses of heat pipes in high-power industrial equipment. It shows examples of the way in which heat pipes can dramatically improve the effectiveness of a cooling system’s fans and/or heat sinks.
