The present invention relates to a smooth, cylindrical stainless
steel tube-shaped
heat exchanger (Figure 1) consisting of three tubes (5-6-7) for vaporizing water (
seawater, pure water, freshwater, or
wastewater) to produce steam (3) by a concentrated
solar thermal energy process, using geothermal heat and other forms of heat with
cogeneration, and by extension, for producing steam and producing
hydrogen and
oxygen by
electrolysis. For its process applications, it takes the form of a
cylindrical tube with a variable
diameter (8-9) depending on the quantity of water (2) to be vaporized, and with a length (8) and width (9) defined and modulated based on the flow parameters of a
heat transfer fluid (1-4) heated by concentrated
solar energy in situ.The stainless steel
cylindrical tube heat exchanger is characterized by its unique
process interaction capacity, whereby
heat transfer occurs by
convection and conduction through the tube (6), i.e.,
heat transfer from a hot body, the oil-carrying fluid (7), to a cooler body (5), which is a water-carrying fluid (2). This can be achieved through simple installations in areas exposed to
sunlight, such as
subsoil or a medium- or high-
enthalpy geothermal well.Once the stainless steel
cylindrical tube heat exchanger is installed and configured,
piping systems carry water (2) into the designated space and then to the heat
transfer system according to the invention. There, the
fluid temperature is raised above its
boiling point, and the water is then returned to the surface via the same
piping system to be vaporized by venting it (3) outside the heat exchanger. The stainless steel cylindrical tube heat exchanger, by its method of use, relates in its functions to methods of vaporizing water (
seawater, freshwater, and
wastewater) by
evaporation.
