Wicking material for heat pipes

Wicking material for heat pipes
Bekaert metal wicking material for heat pipes is made of very fine metal fibers. The material can be randomly stacked and sintered to produce a porous capillary wick. Unlike regular powder wicks, the porosity of fiber wicks can reach a very broad porosity range (between 50 and 85%).

Miniaturization technology

Heat pipe designs are trending toward miniaturization. As the devices are getting smaller, engineers face new challenges in meeting the required performance, size, weight, operating temperature, noise and budget. Each of these factors impacts the choice of thermal management technology. Choosing cutting edge wicking material plays an important role in enabling engineers to meet all project requirements of their design.

High thermal conductivity

Bekaert wicking materials feature high thermal conductivity. This allows a better transfer of high heat loads and fluids in heat pipes. Because the fibers are easy to process, the size of the heat pipes can be significantly reduced to fit into small and complex spaces. Depending on the wick parameters, Bekaert offers a wide range alloys including copper, aluminum, nickel, stainless steel and titanium, with diameters ranging from 12 to 30 µm.
