Abstract:
A fluid dispenser for cooling a fluid to a temperature close to a predetermined desired dispense temperature, comprising:a reservoir of a first liquid coolant, the first liquid coolant circulated to and from the reservoir through a coolant conduit, the coolant conduit providing for a flow of the liquid coolant from the reservoir to a first heat exchanger and to a second heat exchanger, the second heat exchanger including a thermoelectric device having a cold side and a hot side and the coolant liquid in heat exchange contact with the hot side thereof, a reservoir of the fluid to be cooled and a fluid conduit extending there from to the first heat exchanger to provide for heat exchange cooling of the fluid by the liquid coolant and the fluid conduit providing for flow of the liquid from the first heat exchanger to the second heat exchanger for providing heat exchange contact between the fluid and the cold side of the thermoelectric device, and the second heat exchanger cooling the fluid by an amount less than or equal to the temperature reduction thereof provided by the first heat exchanger to thereby closely approach the predetermined desired dispense temperature, and the fluid conduit flowing from the second heat exchanger to a dispense point from which the fluid can be dispensed.
