Round and flat profile heat pipes

8 October 2014 Circuit & System Protection

Advanced Thermal Solutions has introduced a series of copper heat pipes for transporting dissipated power away from hot electronic components. Thirty-three round and flat profile heat pipes are available to meet application needs, which transfer component heat to heatsinks with minimal temperature difference and distribute it efficiently across the length of heat spreaders.

Liquid in the heat pipe turns to vapour by absorbing heat and removing thermal energy from hot component surfaces. This vapour then travels to the cold end of the pipe where it releases latent heat and condenses back to liquid. The liquid returns to the hot interface along an internal copper wick to provide continuous thermal management.

The cold end of the copper heat pipe attaches easily to most heatsinks, providing effective cooling when a heatsink can’t be applied directly to a heat source. All heat pipes are easily hand- or machine-shaped to meet application needs, and they can be friction fit, clamped, soldered or adhesively attached.

Each model in the range has been characterised by ATS for both thermal resistance and maximum heat transport capability. The transport property is determined as a function of the working temperature and the pipe’s angle of inclination.

Every heat pipe consists of a sealed copper tube, internal copper wick structure, and distilled water as its working fluid. Round profile heat pipes come in lengths from 200 to 300 mm and diameters from 4 to 8 mm. Flat profile heat pipes range in length from 100 to 250 mm, widths from 8,2 to 10,5 mm, and heights from 2,5 to 4,5 mm. Weights range from 8 to 33 grams.

The pipes are effective in temperatures between 30°C and 120°C, and their lack of moving parts means they require no maintenance. They are available separately from ATS or in thermal solutions integrating the company’s widely-used Push Pin and maxiFLOW heatsinks. Other fluids and sizes can be accommodated with custom heat pipe designs.
