Lamination type heat exchanger

Abstract

Abstract PURPOSE:To obtain a lamination type heat exchanger which can be easily formed by simple equipment, by applying an adhesive agent to a plate by a printing method such as a silk screen process, stacking the plates thus prepared and hardening the adhesive agent in a furnace at a low temperature to form the lamination type heat exchanger. CONSTITUTION:Passages 3 and 8 on plates are formed into a recessed shape by chemical corrosion treatment or machining applied to one side surface of the respective plates, and other parts than the recessed portion are coated with a thermosetting modified epoxy type adhesive agent 14 having chemical properties, heat-resisting properties and high hardness by the printing of a silk screen process. A plate C12 and a plate D13, both having been coated with the adhesive agent 14, are alternately laminated in the required number of them, clamped together by a jig and subjected to hardening treatment by heating for 20-30minutes at to 150 deg.C form a lamination type heat exchanger 11. The lamination type heat exchanger so formed is easily manufactured and has economical advantage. The required lamination type heat exchanger is thus obtainable in such a simple method that the number of plates to be laminated and bonded is only increased or decreased.
