Abstract
A heating or cooling vessel for heating or cooling a fluid as it flows through the vessel includes an outer tubular shell and an inner tubular member mounted to the outer tubular shell. The inner tubular member includes a central passage defining a first flow path, and a space between the inner tubular member and the outer shell defines a second flow path which communicates with the first flow path at one end of the inner tubular member. A seal member is provided toward the opposite end of the inner tubular member, for cutting off communication between the first flow path and the second flow path. An inlet provides cool fluid to the first flow path, and the fluid circulates through the first flow path and into the second flow path for discharge through an outlet in communication with the second flow path. Heating or cooling elements are disposed in both the first and second flow paths, and are arranged to provide optimal exposure of the fluid to the heating or cooling elements during flow of fluid through the vessel to maximize the velocity at which the fluid is capable of passing through the vessel and thereby the volume of fluid heated or cooled during flow of fluid through the vessel.
