Abstract:
A heat exchanger for transferring thermal energy from at least two fluids to a third fluid, said heat exchanger comprising:first and second elongated hollow metal bodies each made of a single piece, said hollow bodies forming first and second tanks by pressure which is above 50 MPA and having a fluid outlet, the one of at least two fluids flowing through said first and second tanks;a side portion of each tank having a plurality of tube receiving apparatus;a plurality of cooling tubes between the first and second tanks, each of said cooling tubes having a first end inserted into one of said plurality of tube receiving apertures of the first tank and a second end inserted into one of said plurality of tube receiving apertures of the second tank, said plurality of cooling tubes being sealingly joined to each tank in a leak proof manner to permit the one of at least two fluids to flow from the first tank to the second tank; andat least one hollow tubular member adjacent to the fin of one of said plurality of cooling tubes, said hollow tubular member adjacent to the first and second tanks, said hollow tubular member having a passage for flowing the other of the at least two fluids therethrough;whereby the thermal energy of the at least two fluids is transferred to the third fluid.
