norwood, ma, july 2014 - advanced thermal solutions, inc., ats, has introduced a series of copper heat pipes for transporting power dissipation away from hot electronic components. thirty-three round and flat profile heat pipes are available to meet application needs.
the heat pipes transfer component heat to heat sinks with minimal temperature difference. they also distribute heat 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. the vapour 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 heat sinks, providing effective cooling when a heat sink can’t be applied directly on a heat source. all heat pipes are easily hand or machine-shaped to meet specific application needs. they can be friction fit, clamped, soldered, or adhesively attached.
each model in the new heat pipe series has been characterized by ats for both thermal resistance and maximum heat transport capability. the heat 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 200-300 mm and diameters from 4mm to 8mm. flat profile heat pipes range in length from 100mm to 250mm, widths from 8.2mm to 10.5mm, and heights from 2.5mm to 4.5mm. weights range from 8 to 33 grams. they are effective in temperatures ranging from 30c to 120c. other fluids and sizes can be accommodated with custom heat pipe designs.
the heat pipes are available separately from ats or in thermal solutions integrating the company’s widely-used push pin and maxiflow heat sinks. the heat pipes have no moving parts and require no maintenance, says the company.
