Heat exchanger utilizing tubular structures having internal flow altering members and external chamber assemblies

Abstract

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.
