heat pipes and more recent investigations of flat-plate microscale heat spreaders. For heat pipes operating in steady state, there are a number of fundamental mechanisms that limit the maximum heat transfer.

Heat spreaders are ideal for systems that require low profile solutions or are expected to operate under extreme shock and vibration. When an off the shelf heatsink is required we can find a design tailored to your needs. For more bespoke applications, a custom designed heatsink is …

Feb 1, 2004 · Micro heat pipe heat spreaders (MHPHS) with three copper foil layers were designed to allow liquid and vapor flow separation to reduce viscous shear force. Two wick designs, one using 200 μm wide etched radial grooves and the other with 100-mesh copper screens were investigated.

The document discusses micro heat pipes and micro heat spreaders. It covers individual micro heat pipes, arrays of micro heat pipes, and flat plate micro heat spreaders. Modeling, testing, fabrication and new designs are discussed for each area.

Feb 1, 2012 · The objectives of the present study are to experimentally evaluate the thermal performance of a silicon-based micro pulsating heat spreader (MPHS) and investigate the effect of oscillating motion of the liquid slugs and vapor plugs on …

May 1, 2017 · We propose a nanostructured metal foam liquid supply layer that can efficiently provide operating fluid to evaporator hot spots and can be easily integrated within micro heat spreaders.

T-Global’s range of heat spreaders boast excellent thermal conductivity combined with high dielectric breakdown and low weight. Heat spreaders are also immune to radio frequency and electromagnetic interference issues.

In the microwave industry, aluminum diamond metal matrix composites (MMCs) are proving to be an effective way to remove heat from discrete RF power transistors and MMICs. The MMCs are used as heat spreaders between active devices and their mounting surfaces. Thermal models and IR scans of MMC applications show a significant reduction in

Honeywell Sets the Pace in Heat-Spreading Technology. We manufacture custom, precision stamped products from coining, high-speed progressive stamping to multi-stage, high tonnage transfer die stamping. To achieve consistent surface …

Feb 1, 1998 · We review several means that have been proposed for fabricating microscale heat pipe designs within electronic die or as substrate heat spreaders. We then report testing techniques and new experimental results for a silicon spreader design we developed.
