Abstract
A heat exchanger having a horizontally-disposed, elongate shell with a partition extending lengthwise of the shell and interiorly thereof to form upper and lower compartments therein. The shell has end closures with at least one end closure having a flow passage communicating with the lower compartment of the shell for flow of fluid therethrough. A fluid port communicates with the upper compartment for delivering fluid thereto and passages at the edges of said upper compartment permit fluid flow from the upper compartment along the length thereof to wet the interior of the shell wall in the lower compartment. Fluid conduit means is positioned on the exterior of the shell for substantially the entire length thereof to place fluid in the conduit means in heat exchange relation with said shell wall.
Claims14
A heat exchanger comprising, a horizontally-disposed elongate shell, a partition within and extending lengthwise of said shell to form upper and lower compartments within the shell, end closures for said shell with at least one end closure having a flow passage communicating with one of the compartments of said shell, a fluid port communicating with the other of said compartments, means providing for gravity fluid flow from the upper compartment into said lower compartment by flow onto the interior surface of the shell along the length thereof, and fluid containment means substantially enclosing the exterior of the shell for substantially the entire length of the shell to place fluid in the fluid containment means in heat exchange relation with said shell wall.
A heat exchanger comprising, a tubular elongate shell of a predetermined diameter, a transversely curved elongate partition member fitted in said shell to divide the shell into upper and lower compartments extending lengthwise of the shell, said partition member being upwardly convex, end closures for said shell each having a flow passage communicating with the lower compartment of the shell, said shell having a fluid port communicating with the upper compartment, two series of through passages formed in said partition member and extending lengthwise thereof with said series being closely adjacent to the junctures of the partition member with said shell, and fluid conduit means substantially enclosing said shell and closely fitted thereto for good heat transfer and providing for a sinuous flow of fluid from end to end of the shell to maximize the heat transfer between said shell and the last-mentioned fluid.
A heat exchanger comprising, an elongate generally cylindrical shell, a curved partition member within and extending lengthwise of said shell and with opposite edges contacting the shell interior to divide the shell into first and second compartments and with the second compartment having a major part of the volume within the shell, end closures for said shell with at least one end closure having a tubular flow passage communicating with said shell second compartment and of a cross-sectional area closely approximating that of said second compartment, a fluid port communicating with the first of said compartments, a series of flow passages along each edge of said partition member for controlling fluid flow between said compartments and causing fluid flow along the curved interior surface of said shell, and fluid conduit means wrapped around and substantially enclosing the exterior of said shell in a manner to have a generally cylindrical exterior configuration and operative to place fluid within the fluid conduit means in heat exchange relation with the shell.
