ABSTRACT:
A heat exchange device includes a vessel having a top end and a bottom end, and having a first chamber located in the vessel and a second chamber located in the vessel and separated from the first chamber by a partition. An elongated tube for conveying liquid to be cooled is located in the second chamber and is arranged in a convolution. A port is connected to the first chamber for supplying coolant to that chamber, and a flow path extends between the first and second chambers for permitting fluid flow between the first and second chambers. The flow path is a space between the upper edge of the partition and the top end of the vessel, and the upper edge of the partition uniformly distributes coolant over the elongated tube. A port is located in the second chamber for evacuating coolant from the second chamber.
