A beverage cooler is provided with an improved thermoelectric chiller unit for chilling a supply of water or other selected beverage within a cooler reservoir. The improved thermoelectric chiller unit includes a thermoelectric heat transfer module captured by a spring mount with substantially uniform pressure distribution between a chiller probe for chilling the water within the cooler reservoir, and a heat exchanger for dissipating heat drawn from the chilled water. The cooler reservoir has a faucet mounted thereon for on-demand dispensing of the water, and is mounted as a removable unit within a cooler housing with a bottom wall of the reservoir defining an inverted cup-shaped receptacle for close slide-fit reception of the chiller probe.
