ONE-PIECE EXTRUDED RADIATOR/HEAT EXCHANGER UNIT, SERIES AND MODULES THEREOF AND MANUFACTURING PROCESSES THEREOF

摘要

A one-piece radiator/heat exchanger unit comprising lateral tubes and central tubes for heat exchange between a first fluid preferably flowing or not flowing inside one of said tubes and a second fluid, preferably flowing, outside one of said tubes, each of the tubes having a cross-section, walls and a pair of ends, the said lateral tubes being symmetrically positioned adjacent to the said central tubes, the axis of each said tubes being about parallel and positioned about the same plan or positioned in parallel plans, each of the lateral tubes sharing a common wall with at least one of the central tubes and the lateral tubes being, at least two by two, connected by the walls of the central tubes that are not shared with the said lateral tubes. A radiator/heat exchanger series, which includes at least n of this one-piece radiator/heat exchanger units. A module consisting of a multiplicity of series of interconnected one-piece radiator/heat. Use of a one-piece radiator/heat exchanger unit for the reversible storage of heat energy. Process for the manufacturing radiator/heat exchanger.
