ABSTRACT:
The invention provides an apparatus for moving thermal energy with respect to at least one of a beverage and a food product positioned in a vehicle or a stationary beverage machine. The apparatus includes a vortex tube positionable in a vehicle or a stationary beverage machine. The vortex tube includes an inlet and a cold outlet and a hot outlet. The vortex tube divides a primary air stream received in the inlet into a cold air sub-stream exiting the cold outlet and an a hot air sub-stream exiting the hot outlet. The apparatus also includes a containing member having a first wall with an inner surface for receiving a product. The containing member also includes a second wall surrounding the first wall to define a first cavity. The apparatus also includes a first fluid line extending between the first cavity and one of the cold and hot outlets for communicating one of the cold and hot air sub-streams to the first cavity. The apparatus also includes a third wall disposed between the first and second walls for dividing the first cavity into outer sub-cavity for receiving the air sub-stream and an inner sub-cavity for receiving a thermal fluid.
