Abstract

A watercooler is provided with a vessel for storing water therein; a heater for boiling the water in the vessel; a pump for lifting the boiled water; a primary cooling unit (e.g., air-cooled heat exchanger tube and a fan) for subjecting to primary cooling the boiled water lifted by the pump; a secondary cooling unit (e.g., the fan, a heat-dissipating-side thermal conductor, a thermoelectric module, a heat-absorbing-side thermal conductor, and a cold water pipe) for subjecting the water, which has been subjected to the primary cooling, to secondary cooling by using the thermoelectric module; and a service unit for dispensing the cold water subsequent to the secondary cooling.
