Abstract

DC60 (24/02/54) in the manufacture of dual wall plate heat exchangers. That has been used The double-walled binders (5, 6) consist of areas (5a, 5b) that are connected and sealed to each other and Around the heat exchanger passageway, this is achieved by giving such area (5a, 5b) the shape. Which consists of areas that do not overlap, therefore welding using a binder It occurs by absorption in small channels of binder from areas of another sheet. In the manufacture of dual wall plate heat exchangers That has been used The double-walled binders (5, 6) consist of areas (5a, 5b) that are connected and sealed to each other. Around the heat exchanger passageway, this is achieved by giving such area (5a, 5b) the shape. It consists of areas that do not overlap, so that the bonding process occurs. By absorption in a small cavity of the binder from the area of another sheet.

1.How to produce a plate type heat exchanger This consists of a number of sheets (5-8) that are stacked on top of one another. Which confines to two or more separate fluids to exchange heat through the plates. And which sheet of material (5-8) has Double wall design In order to prevent fluid that may leak through the wall of the sheet material (5-8) from entering the Another fluid path The double walls of each such sheet are closely connected. It is sealed around the edge of the passage in the sheet (5-8), which has a characteristic Prior to the binder welding operation, each double-walled plate (5-8) has been provided with a binder on a surface to be joined to a double-walled (5-8) plate. Another one and a unique one is The area of the contact surfaces of the two panels which form a sheet. The round double-wall type (13 in fig. 3 and 8; 18,19 in fig. 13; 20,21 in fig. 16) of the passageway is designed to be partially covered. 2. The method, according to claim 1, is characterized by the edges (13 Fig. 3 - 7) of the in-wall passages (5a, 5b), which are joined together in the plate (5) of the type heat exchanger. The plates are the same diameter. And arranged the edges with notches (14, 15) arranged relative to each other 3. The method according to Clause 1, which has unique characteristics, is The area around the edge (13, Fig. 8 - 12) of the two wall passages (5a, 5b) in the material plate (5) of the heat exchanger has holes (16, 17) holes (17). In the wall (5a), place it at an angle with the hole (16) in the wall (5b), which is the other wall. 4. Method according to Clause 1, which is unique as follows: The two walls (5a, 5b) of the heat exchanger material plates were arranged. There are passageways arranged in relation to each other. Which let there be The free area in contact with the contact surface area around the opening of the pass (Fig. 13 - 15). 5. Method according to Clause 1, which is unique as follows: Two holes in a pair of walls that form a funnel. Passed in the plate, the material of the heat exchanger has an oval shape. And placed at an angle (Fig. 16 - 20) 6. Plate-type heat exchanger, manufactured in accordance with the method described in which of the Claims? One of the preceding claims
