  • a multipass heat exchanger comprising a plurality of longitudinal passages constructed by superposing a plurality of metal sheets one upon the other with a spaced relation for the purpose of heating or cooling an electric plating liquid and other liquids and adjusting the temperature of these liquids.
  • Such kind of heat exchanger has the disadvantage that each of metal sheets must be welded to another metal sheet whenever the former is disposed on the latter and each passage thus formed must be subjected to a leak test during assembling thereof, and as a result, it is very troublesome to fabricate the heat exchanger and hence the fabrication thereof could not be effected in a mass production scale.
  • An object of the invention is to provide a heat ex changer comprising a plurality of composite cylindrical shells each of which is composed of a pair of trough shaped elements each of which is welded into one integral body and subjected to a leak test and then assembled into the heat exchanger with a minimum of time and labor.
  • Another object of the invention is to provide a heat exchanger having an excellent anti-corrosive property and thermal efficiency.
  • a feature of the invention is the provision of such an improved heat exchanger comprising a plurality of composite cylindrical shells concentrically arranged and spaced apart one from the other, each composite cylindrical shell being composed of a pair of trough shaped elements each of which consists of two segments made integral into one body and one of these segments has a number of longitudinal ribs spaced apart one from the other and extending in a lengthwise direction throughout the total length of the segment, and another segment has a number of peripheral ribs spaced apart one from the other and extending in a peripheral direction throughout the total periphery of the segment, the latter segment surrounding the former segment to form a number of first elongate passages extending throughout the total length of the segments and said composite cylindrical shells being closed at their substantially upper and lower portions by blanking plates to form a plurality of second elongate passages extending throughout substantially total lengths of the composite cylindrical shells in parallel with said first passages, a pair of openings provided at the top and base of said composite cylindrical shells and communicated with said first passage
