Wave-fans and wave-fans with heat sinks
InactiveUS7136285B1Increase local velocityLarge heat flowPropellersSemiconductor/solid-state device detailsHeat flowWave shape
A wave-fan comprises a wavy surface, generally sinusoidal in the direction of rotation, which rotates in close proximity to the fins of a heat sink. The wave-plane fan is suitable for use with a flat heat sink, and a wave-ring fan is suitable for use with a cylindrical heat sink. There are no airfoils as in a prior art fan. Instead, the ridges of the wave-fan agitate the air between the fins of the heat sink as each ridge passes, breaking down the boundary layer and effecting good heat flow into the air. In some embodiments of the wave-fan, the outer surfaces are smooth, so it is not a hazard to intruding fingers, so in many applications it may be used without a guard or enclosure. Incidental centrifugal force provides some airflow through the fan to transport the heated air away from the fan. Also, the configuration of the fan tends to keep contamination in the air out of the heat sink fins, so an inlet air filter may not be needed. Because the net airflow through the fan is low, less power is required and it is very quiet.

Redispersible polymer powders prepared from low carboxylation styrene butadiene-based latex
InactiveUS20110257305A1Low viscosityFacilitates spray dryingSpecial tyresPolymer adhesivePolymer science
A water redispersible polymer powder is produced by drying an aqueous mixture of a low carboxylation, low Tg, large average particle size water insoluble film-forming polymer latex or emulsion and a colloidal stabilizer. The latex polymer may have an average particle size of 2000 Å to 5,000 Å, and an amount of carboxylation of 0.1% to 2.75% by weight of at least one ethylenically unsaturated dicarboxylic acid, salts or mixtures thereof, based upon the weight of the polymer. Dispersions containing the polymer and a polyvinyl alcohol as a colloidal stabilizer exhibit an unexpectedly low viscosity which facilitates spray drying and permits use of high solids content dispersions with low pressure spray drying to increase production efficiency. Cement compositions such as mortars, which contain the redispersible polymer powder exhibit unexpectedly lower rates of viscosity buildup for better workability or troweling, faster set time, and superior heat flow characteristics.
