Abstract
The present invention relates to a heat exchanger for transmitting heat from a gaseous primary fluid to a liquid secondary fluid. In particular, the present invention relates to the thermal exchange means proper, the main feature of which is the use of a diverging tube sheet including a plurality of four-lobe cross-section tubes.
Claims3
A heat exchanger for thermal generators, said heat exchanger comprising a plurality of heat exchanger tubes, arranged in a spoke-like configuration, wherein each said exchanger tube has a four-lobe cross-section, wherein central-most heat exchanger tubes of said heat exchanger tubes are diverging from one another at their ends and a rest of said heat exchanger tubes are spaced apart a same distance at either end of a heat exchanger metal shell, wherein said four-lobe cross-sections are arranged, either with a symmetrical or an asymmetrical pattern, on a crown about a central hollow body having a circular cross-section, and wherein each said exchanger tube has a tube construction defined by a simultaneous translation and rotation of said four-lobe cross-section on a main axis of said heat exchanger.
