Summary: | A beverage cooler (10, 100, 200) includes a heat pump (12) having a cooling element thermally coupled to a negative-heat-energy accumulator (14). The accumulator (14) includes a heat-energy dispersion arrangement (16) formed from thermally conductive material which is in thermal contact with a quantity of phase- change material (18) having a phase-change temperature above zero Celsius. A conduit (20) for the beverage defines a circuitous path thermally coupled to accumulator (14). The heat pump (12) draws heat energy predominantly from the phase-change material (18) 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 (20), even under zero-flow conditions. This ensures that the accumulator (14) can be fully charged during periods of low beverage dispensing demand without risk of freezing the beverage within conduit (20). |
