Abstract: 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.

Abstract: This invention concerns a heat-resistant assembly having a heat-resistant block conformed to the contours of boiler tubes and the surface of their connecting rib. The heat-resistant assembly has an arm which protrudes from the surface of the rib toward the heat-resistant block and which has a catch on the end. The block has an indentation in which the catch on the arm engages. The block can be hung on or removed from the tube assembly by means of the arms and indentations. The heat-resistant assembly is further distinguished by the fact that a space is created between the end of the arm and the indentation of the block. A fusible substance, which will melt when the temperature of the arm exceeds a given value, is placed in the space. The heat-resistant assembly is further distinguished by the fact that an indentation is formed in the block in which a heat-resistant sleeve is adhered to engage the arm. This arrangement makes it possible to manufacture the heat-resistant block using press molding.

Abstract: In a fin forming step, fins of heat exchangers are formed into a connected state where the fins are connected to each other via a parting portion. In a fin attaching step, the fins in the connected state are temporarily attached to the respective heat exchangers. In a fin fixing step, an integrated heat exchanger in which the fins are temporarily attached is passed through a heating oven to braze the fins to the respective heat exchangers. In a fin separating step W4, the fins in the connected state of the respective heat exchangers are separated from each other in the parting portion. Therefore, each of the heat exchangers can independently perform a heat exchanging operation without being affected by heat conduction from the other heat exchanger via the fins.

According to the invention, the plates (9, 10), with solder layers (8) between them, are stacked on one another and compressed in the cold state before the solder diffusion process. With this provision, the use of complicated pressing tools in the actual solder diffusion process is avoided.
