HEAT EXCHANGER UTILIZING TUBULAR STRUCTURES HAVING INTERNAL FLOW ALTERING MEMBERS AND EXTERNAL CHAMBER ASSEMBLIES

摘要

A heat exchanger includes at least one cylindrical tubular member formed from a tubular structure and chamber assemblies. A plurality of flow altering members are coupled at predetermined intervals within the tubular structure. The flow altering members have an angled surface on their respective sides facing the flow of a heat exchange medium. Pairs of inlet orifices and outlet orifices are formed on the wall of the tubular structure at the same intervals as the flow altering members. Chamber assemblies are coupled as a full or partial collar on the exterior of the tubular structure. Each chamber assembly is hollow, permitting fluid flow within, and is in fluid communication with a corresponding inlet orifice, outlet orifice pair so that the heat exchange medium repeatedly flows out of the tubular structure into a chamber assembly and back into the tubular structure. Multiple cylindrical tubular members may be coupled between manifolds.

1. A heat exchanger having at least one cylindrical tubular member, the cylindrical tubular member including:
a tubular structure with an inlet at one end and an outlet at the other end and having a plurality of inlet orifices and outlet orifices, the plurality of inlet and outlet orifices being spaced along respective sides of the tubular structure such that for each inlet orifice there is a paired outlet orifice disposed on the generally opposite side of the tubular structure; a plurality of generally semi-cylindrical chamber assemblies attached to the exterior surface of the tubular structure, each chamber assembly having first and second generally planar walls, the first and second generally planar walls surrounding a portion of the tubular structure to at least partially define a generally semi-cylindrical chamber external to and partially surrounding the tubular structure, a first set of chamber assemblies being positioned on the tubular structure such that each of its respective chambers is in fluid communication with a corresponding inlet and outlet orifice pair and a second set of chamber assemblies being positioned on the tubular structure such that each of its respective chambers is in fluid communication with a corresponding inlet and outlet orifice pair, the chamber assemblies in the first and second sets being spaced along the tubular structure such that for each chamber assembly in the first set, there is an associated chamber assembly in the second set which is disposed on the generally opposite side of the tubular structure; and a plurality of flow altering members disposed within the tubular structure, each flow altering member having a first side which has an angled surface facing two corresponding inlet orifices and a second side which has an angled surface facing the two outlet orifices respectively paired with the two corresponding inlet orifices.
