ABSTRACT:
A water cooler is provided with an improved chiller system of the type having a thermoelectric chiller module for maintaining a supply of water at a reduced and refreshing temperature level. The chiller system comprises the thermoelectric chiller module having a cold side thereof in thermal communication with a supply of water to be chilled, and a hot side thereof exposed within a manifold defining a heat transfer chamber filled with a heat exchange medium such as water. An impeller located centrally within the heat transfer chamber circulates the water directly against the hot side of the thermoelectric module, from which the water then flows radially outwardly through a plurality of hollow fin elements and is recirculated back to the impeller. In the preferred form, the impeller is coupled by a hermetically sealed magnetic coupling to an air flow fan disposed outside the manifold for providing a cooling air flow over exterior surfaces of the hollow fin elements.
