Surface Pro 3 Thermal Module Design
Keywords: innovation, integration, thermal module
The pursuit of thinner and lighter mobile devices drives innovation in thermal design, and Surface Pro 3 exemplifies this. Shedding over 100 gf of weight and thinner by 5 mm, Surface Pro 3 boasts a 1.4” larger display with 50% higher resolution, an i7 processor option, and 28% more battery life. Engineering the Surface Pro 3 required daring efforts from all the sub systems, and the thermal module was no exception. The Surface Pro 3 thermal module is 51% lighter and 35% thinner than the Surface Pro 2 thermal module while still providing sufficient thermal performance for the same line of Intel 4th generation Core Processors. Additionally Pro 3 had to accommodate a single blower instead of two, a 50% reduction in heat pipe thickness and a 34% reduction in overall footprint. Achieving such drastic reduction in size and weight required noteworthy integration at the thermal module level resulting in a state of the art, patent pending, super-compact heat exchanger.
