A series of copper heat pipes for transporting power dissipation away from hot electronic components, has been introduced by Advanced Thermal Solutions. These transfer component heat to heat sinks and distribute heat across the length of heat spreaders. 33 round and flat profile heat pipes are available for a range of applications.
Each model in the series has been designed for both thermal resistance and heat transport. Liquid in the heat pipe turns to vapour by absorbing heat and removing thermal energy from hot component surfaces. This vapour travels to the cold end of the pipe where it releases latent heat and condenses back to liquid. The liquid then returns to the hot interface along an internal copper wick to provide continuous thermal management.
The heat pipes provide cooling even when a heat sink cannot be applied directly onto a heat source, as the cold end attaches to many heat sinks. The pipes, which are hand or machine-shaped, can be friction fit, clamped, soldered or adhesively attached.
Each heat pipe consists of a sealed copper tube, internal copper wick structure, and distilled water as its working fluid. Round profile heat pipes are available in lengths from 200-300mm and diameters from 4.0-8.0mm. Flat profile heat pipes are available in lengths from 100-250mm, widths from 8.2-10.5mm, and heights from 2.5-4.5mm. Weights range from 8-33g. Both types operate in temperatures from 30-120°C. Other fluids and sizes are available on request.
