Geometry for Gradual Heat Exchanger

A novel heat exchanger with gradual change geometry has a significantly higher efficiency than conventional heat exchangers. For example, the novel heat exchanger may have a coefficient of performance (COP, defined as ratio of kilowatts of heat transferred per milliwatt of mechanical energy dissipated) of 14, which is much higher than a COP of 0.25 to 3 for conventional heat exchangers. Applications of such a novel heat exchanger are an energy savings in pre-heating of clean cold water from used warm water and heat recovery in building ventilation. Rapid cooling of wort in beer making is another possible application.

This technology is claimed in a pending patent application. We are seeking an industrial partner interested in its commercialization.
