Recent developments in fibre wick structures however, enable Columbia-Staver to offer Heat pipes with a thickness as small as 0.4mm. The body of these ultra-thin heat pipes is made of copper with pure deionised water as the working fluid. The Ultra-thin heat pipes are easily able to transfer heat fluxes in the range of 1?6 W/cm2 often required mobile-handheld chipsets.

Ultra-thin heat pipes can come in a variety of lengths, widths and thicknesses.
