<p>A process for economica1ly forming and assembling heat exchangers is disclosed. The process begins with a roll of synthetic resin (10) which is heated and then impressed with a series of alternating panels (18) and hinges (30). The hinges are formed so as to provide for an accordion fold. The formed strip of material is then cooled, trimmed, measured and cut. Thereafter, the strip of material is folded in an accordion fashion. The folded core may be bonded or constrained so as to form two sets of fluid flow passages in an alternating manner. Depending upon the design of the panels formed in the strip of material, the cores will either be counterflow or cross flow. In addition, a housing is thermo formed and then assembled with the core to complete the heat exchanger.</p> |
