Heat exchangers of this type are particularly easy to assemble and can be produced very economically or be realized. In particular, they can be used to recover part of the heat to be renewed Air in a room, for example a workshop, to reheat the air to be circulated or to recover part of the heat from the air exiting an oven to warm up eggs Intake air can be used.

Meanwhile, the efficiency of the heat exchanger increases if the flow-limiting channels for the fluids in the uurehlässen are collinear. The width of the heat exchanger, however, is limited, and because you have the height of the heat exchanger cannot enlarge indefinitely, the throughput through the heat exchanger is also limited.

The object of the invention is to create a heat exchanger in which the performance and the throughput are simple and can be increased without difficulty.

This object is achieved according to the invention in that the collecting line is one in the longitudinal direction opposite each column running, running approximately perpendicular to the plates and at the dividing line of the two adjacent end surfaces abutting partition and has transverse walls on both sides of the partition running in the longitudinal direction, which form the connection between the other end surface and the other channel separates.

The present invention makes it possible to increase performance by juxtaposing multiple columns of panels, thanks to a manifold, the currents enter the passages of the various columns.

flow and flow out of them.

According to the invention, the primary and secondary currents are at the entrance and exit each formed by the adjacent faces of the pillars Ends of the heat exchanger in two parallel to the plates Running channels divided and open into a collecting line, which is one in the longitudinal direction for each column and perpendicular to the plates and at the line of separation of the two adjacent end surfaces abutting partition wall and on both sides of the partition wall has a transverse wall, which the connection between one of said end surfaces and one of the channels or between the other end surface and the other channel separates.

According to a particular embodiment of the invention have the partition walls running in the longitudinal direction. a basically triangular shape, - one of which has an edge is provided with an edge which is bent at right angles to the edge to form one of the transverse walls rests on an adjacent partition, the bent edge itself being provided with a wedge, which is bent parallel to the plates and on which a wall is attached to separate the two lines can be.

Further advantageous refinements and developments of the invention can be found in the subclaims.

On the basis of an exemplary embodiment shown in the drawing, the invention is intended to provide further advantageous Refinements and improvements as well as further advantages are explained and described in more detail.

Ren short edges 6, ö of the plate 2 in the same way with upwardly bent edges 12, 14 provided are.

If (see Pig. 2) a large number of type 1 or type 2 plates are alternately placed on top of one another in such a way that each comes to rest on the bent paths of the plate arranged directly below, then a column 15 is formed from plates, one of which each has a first passage 16, which, for example, is shown schematically by the arrow 17 from one Primary current can be flown through by a second Passage 18, which is shown for example in the opposite direction from one shown schematically by the arrow 19 Secondary current can be flowed through, abtiennt, so the two currents can exchange their heat or transfer their heat to one another. Either of the two have opposite front sides 2o and 21 of the heat exchanger formed in this way two adjoining jindob er surfaces 22, 23 and 24, 25. Pie passages 16 open into the .rindoberflachen 22 and 24, which are created by arranging the edges 6 and 8 one above the other, and the passages 1ö open into the indoberflache 23 and 25, which are formed by arranging the edges 5 and 7 one above the other.

In Pig. 2, only a section of the column 15 is shown. In the meantime, one can determine the height of the heat exchanger do not enlarge indefinitely, otherwise the heat exchanger will very quickly reach an unacceptable height would. To increase the fluid throughput through the heat exchanger, several are used such columns as the 15a and 15b side by side, can uses for the passage of the primary current 17 in the area of the front sides 2o of the columns the ±) ndob erf lache

the column 15 (passages 16) and the "adjacent End surface 23a of column 15a (.passages 16a) etc. and for the passage of the secondary flow 19 the end surface 22a of the column 15a (passages 16a) and the "adjacent end surface 23" b of the column 15h (Passages 16h) and so on. On the side of the front sides 2o of the heat exchanger, a large number of flow sections lying vertically (i.e. perpendicular to plates 1 and 2), the primary and Secondary currents are alternately one above the other. As you can see, the arrangement in the area of the Front sides 21 of the heat exchanger the same; the primary current entering through end surfaces 22 and 23a, emerges from end surfaces 24 and 25 to form a vertical partial flow of the primary flow out, etc.

TJm the primary and secondary currents in the area, the front Channeling 2o is placed opposite each of the lines 26, 26a and 26b passing through the intersection of the end surfaces 22-23, 22a-23a, 22b-23b are formed, a longitudinally extending, vertical dividing wall 27, 27a and 27b, i.e. perpendicular to panels 1 and 2. These partitions are generally triangular in shape in the sense that the edge of each of these partitions, which opposed to that which rests against the lines 26, 26a, 26b, has two edges 20, 29, which are on cut halfway up the columns. The angle formed by the edges 28 and 29 is advantageous for reduction the weight between 50 and 12G ° with the theoretical optimum at 60 °; but Dimensional considerations can also lead to choosing a larger angle.

The edge 28 of the partition wall 27 is provided with an edge 3o provided that at right angles in front of the end surface 23 has turned; the edge 29 of the partition wall 27a is provided with a rim 30a which is in front of the end surfaces 22 and 23a is bent at right angles, etc.

The edges 3o, 3oa and 3ob are themselves at their ends lying at the intersection of the edges 2ä and 29 with angles or wedges 31, 31a and 31b, which are bent horizontally by a selected angle and over which a horizontal, parallel to the plates 1 and 2 running separation takes place, provided. The width of the bent edges 30a and 30b is equal to the width of the panels 1,2 in such a way that they form transverse walls covering the upper half of the end surfaces 22, 3.3a and the lower half of the end surfaces 22a and 22b, respectively. The flow part of the primary flow which flows into the heat exchanger through the end surfaces 22, 23a is thus directed into the space located between the partition walls 27 and 27a, being through the partition 30a from the space above the partition line 32 , is separated and communicates with the room below this dividing line. On the other hand, the flow part of the secondary flow, which leaves the heat exchanger through the end surfaces 22a and 22b, is directed into the space which lies between the ends 27 and 27b, it being passed through the partition wall 30b from the space below the dividing line 32 is arranged, is separated and is in connection with the space which is arranged below this dividing line. The primary flow 17 and the secondary flow 19 then circulate below and above the dividing line 32, respectively.
