Abstract:
1. A vaporizer system comprising: a source of hot fluid; a source of liquid to be vaporized: a plurality of first cells each having an internal flow passage for a liquid to be vaporized and having opposed ends, a liquid inlet at one of said ends, a vapor outlet at the other of said ends and an internal maze for fluid flow extending between said ends, the liquid inlet connected to the source of liquid to be vaporized to receive the liquid therefrom, the vapor outlet connected to another component of the system to supply vaporized liquid thereto; a plurality of second cells, each having an internal flow passage defined by spaced walls for a hot fluid and having opposed ends, a hot fluid inlet at one of said ends, and a hot fluid outlet at the other of said ends, each of the hot fluid inlets connected to the hot fluid source to receive the hot fluid therefrom; said first and second cells being arranged in a stack in alternating fashion and in heat exchange relation with adjacent ones of said cells and with the ends of the first cells having liquid inlets being closely adjacent the ends of the second cells having hot fluid outlets and with the ends of the first cells having vapor outlets being closely adjacent the ends of the second cells having hot fluid inlets to provide for countercurrent flow of said liquid to be vaporized and said hot fluid within the vaporizer; and a turbulator in said hot fluid flow passage in each second cell and extending between and bonded to the spaced walls thereof, said turbulator having a length beginning adjacent the ends of the corresponding second cell having said hot fluid outlet and terminating well short of the end having said hot fluid inlet so that said hot fluid passage is characterized by the lack of a turbulator for a distance adjacent said hot fluid inlet.
