A heat exchanging device includes a receptacle having a chamber for receiving a fluid medium, a housing received within the receptacle and having an outer peripheral wall arranged to allow the fluid medium to flow into the housing via the upper portion of the outer peripheral wall, and having an inner peripheral wall having a lower portion directed toward the lower portion of the receptacle. A circulating device may circulate the fluid medium to flow from the upper portion of the housing and then toward the lower portion of the receptacle. A coil is arranged to have a fluid material to flow in a direction opposite to that of the fluid medium, to allow the fluid medium to transmit and to release heat to the fluid material.
