U.S. patent application 20160313047 (inventors Avner Sodot and Shaul Hanuna, Israel):
"A beverage cooler includes a heat pump having a cooling element thermally coupled to a negative-heat-energy accumulator. The accumulator (14) includes a heat-energy dispersion arrangement formed from thermally conductive material which is in thermal contact with a quantity of phase-change material having a phase-change temperature above zero Celsius. A conduit for the beverage defines a circuitous path thermally coupled to accumulator. The heat pump draws heat energy predominantly from the phase-change material so as to ensure that a temperature of the phase-change material is reduced by at least as much as the temperature of the beverage within conduit, even under zero-flow conditions. This ensures that the accumulator can he fully charged during periods of low beverage dispensing demand without risk of freezing the beverage within conduit."
