Celsia Technologies has announced the availability of its MicroSpreader line of thermal management products equipped with an optimal cooling design for all types of systems and devices.

The MicroSpreaders, touted to be the thinnest and lightest two phase heat spreaders in the industry, are built on Celsia's patented micro thermofluidic design. These devices are flexible to easily integrate with any electronic device and minimise the required space for cooling. In addition to being thinner and lighter, the 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.

"As a manufacturer and provider of thermal management components and accessories for the electronics industry, we are always looking for the best new innovative solutions to offer to our customers," said Gary Kuzmin, director of ThermaFlo. "We are integrating the Celsia MicroSpreaders into a total solution for telecom base stations and LED lighting applications. The solution, including the high-performance MicroSpreaders, will meet the highest quality standards."

With thermal conductivity of more than 5,000W per metre Kelvin, the MicroSpreaders have a heat transfer capacity 25 times greater than aluminium and 13 times greater than copper, the two most commonly used metal heat conductors. In a given application, these devices can increase the cooling system's performance by 25 to 60 per cent over other industry solutions. In the area of LED lighting, tests have shown that MicroSpreaders can improve the life of devices by 10-15 times.

Measuring at 1.4mm thick and weighing 25 gms, the spreaders boast a 28 per cent reduction in thickness and 33 per cent reduction in weight over competitive products. The razor thin plates or tubes can be built to fit a variety of small and large devices. With no mechanical parts, the 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 vapour and back to water, removing excess heat. The MicroSpreaders can be attached directly to the heat source to enhance cooling capability.

The MicroSpreaders are already shipping worldwide through the company's strategic partnerships. Pricing starts at less than Rs.462.10 ($10) per unit.
