SOLVENTLESS FORMING METHOD FOR HEAT EXCHANGER PANELS

A method for forming thermoplastic heat exchanger panels without using solvents, wherein a co-extruded film is used to provide a layer of toughened, heat-sealable nylon on a layer of regular nylon, and using such panels in a gas-assisted press bonding process to form the heat exchanger panels.

Zusammenfassung:	A method for forming thermoplastic heat exchanger panels without using solvents, wherein a co-extruded film is used to provide a layer of toughened, heat-sealable nylon on a layer of regular nylon, and using such panels in a gas-assisted press bonding process to form the heat exchanger panels. Selon un procédé permettant de former des panneaux thermoplastiques d'échangeur thermique sans utiliser de solvants, on utilise une feuille co-extrudée pour constituer une couche de nylon thermoscellable renforcé sur une couche de nylon ordinaire, puis on applique auxdits panneaux une technique pneumatique de liaison par presse, de façon à former les panneaux d'échangeur thermique.
