    摘要: 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.

    摘要: A frame or a pressure plate (end plate) has two horizontal sides and two vertical sides and is provided with holes or recesses for fastening means used for clamping heat exchange plates between the end plates. The end plate has only one hole or recess (6a, b; 7a, b; 8a, b; 9a, b) at the upper and lower horizontal side, the hole or recess (6a; 7a; 8a; 9a) at the upper side being located on one side of the vertical center line (L) and the hole or recess (6b; 7b; 8b; 9b) at the lower side being located on the other side of the vertical center line (L). The end plate has at least one hole or one recess (10a, b) at each vertical side such that a line between the uppermost hole or recess on each side of the vertical center line forms an angle with the vertical center line, larger than 0.degree. but less than 90.degree..

    摘要: In a plate heat exchanger having a frame plate and a pressure plate, at least one of these plates has holes for flow of the heat exchanging media to and from respective passages in the pack of heat exchange plates. Each of these holes has a lining of corrosion-resistant metal comprising a hollow cylinder with thin flanges at its opposite ends engaging opposite sides of the frame plate or pressure plate. One of these flanges has a seamless connection with the hollow cylinder and is sealingly compressed between a heat exchange plate and an undepressed surface of the inner side of the adjacent frame plate or pressure plate. Lining of the hole is effected by plastically deforming a metal disc into a hollow cylinder with a flange at one end, inserting the other end of the cylinder through the hole to engage the flange with said undepressed surface, and then providing said other end of the cylinder with a flange engaging an undepressed surface of the outer side of the frame or pressure plate.
