Title:
【発明の名称】熱可塑性パネル熱交換器の製造方法
Document Type and Number:
Japanese Patent JP2966427
Kind Code:
B2
Abstract:
A method is disclosed for the manufacture of panel heat exchangers from thermoplastic polymers. At least one sheet is coated with a coating that facilitates bonding of the polymer to itself under the influence of heat. Two sheets, at least one of which has been coated, are placed between moulds (20) in a press. At least one of the moulds has grooves (25) corresponding to the pattern of fluid flow passages to be provided in the panel heat exchanger. The moulds are heated and an inert gas e.g. nitrogen, is applied and passed through the fluid flow passages, to assist in the formation of the passages and to remove any volatile material from the coating. The preferred polymer is polyamide and the preferred coating is benzyl alcohol, phenol and polyamide. The heat exchangers may be used in a variety of end-uses, especially in automotive end-uses.
