Celsia Technologies has unveiled MicroSpreaders, a new line of thermal management products equipped with an optimal cooling design for all types of systems and devices. Built on the company's patented microthermofluidic design, these new devices are touted to be the thinnest and lightest two-phase heat spreaders in the industry.

In addition to being thinner and lighter, MicroSpreaders deliver significantly higher thermal conductivity (heat transfer capacity) versus conventional options such as aluminium, copper, heat pipes and other metal materials used for cooling, Celsia said. With thermal conductivity of more than 5,000W per meter Kelvin, MicroSpreaders have a heat transfer capacity that's 25 times greater than aluminium and 13 times greater than copper, the two most commonly used metal heat conductors, according to the company. In a given application, these devices are said to increase the cooling system's performance by 25 to 60 percent over other industry solutions.

Measuring at 1.4mm thick and weighing 25g, the spreaders boast a 28 percent reduction in thickness and 33 percent reduction in weight over competitive products, Celsia said. The thin plates or tubes can be built to fit a variety of small and large devices. With no mechanical parts, MicroSpreaders are noise- and vibration-free, eliminating the need to reconfigure product design to accommodate the cooling device. Within the plate or tube is an extensive network of micro channels through which pure water moves rapidly, changing from water to vapor and back to water, removing excess heat. The MicroSpreaders can be attached directly to the heat source to enhance cooling capability.

MicroSpreaders are already shipping worldwide through the company's strategic partnerships. Pricing starts at less than $10 per unit.
