Title (EN) A METHOD OF MANUFACTURING A PLATE HEAT EXCHANGER
(FR) PROCEDE DE FABRICATION D'UN ECHANGEUR DE CHALEUR A PLAQUES
Abstract: front page image
(EN)In manufacturing brazed, double wall plate heat exchangers the double walls (5, 6) should comprise areas (5a, 5b) connected and sealed to each other around the port holes of the exchanger. This is obtained thereby that the said areas (5a, 5b) are shaped such as to comprise areas not covering each other. The brazing is thus established by capillary suction of brazing material from other plate areas.
(FR)La présente invention concerne un procédé de fabrication d'échangeurs de chaleur à plaques à doubles parois brasées dans lesquels les doubles parois (5, 6) comprennent des zones (5a, 5b) reliées et scellées entre elles autour des orifices de l'échangeur. Les zones précitées (5a, 5b) sont formées de telle manière qu'elles comprennent des régions qui ne se chevauchent pas. Le brasage s'effectue par conséquent par aspiration capillaire du matériau de brasage à partir des zones des autres plaques.
