Abstract

The invention relates to the field of heat engineering and is an improvement of the invention according to the authors. St. No. 1032320. The purpose of the invention is to intensify heat exchange and increase compactness. Tubular flat coils 2 are installed between the perforated plates 1. Cylindrical nozzles 6 and 7 are connected to the end sections of the coils 2, one of which has a choking hole in the wall. As a result, it is easy to test and collect, as well as the possibility of making snakes with flat contacting surfaces and cylindrical protruding ends at a constant pressure of the filler in the coil and punching it on a vertical press. 4 il.

The invention relates to plate heat exchangers and is an enhancement of the known device according to the basic author. ev 1032320.

The purpose of the invention is to intensify heat exchange and compactness.

Figure 1 shows the proposed heat exchanger, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - section bb In figure 2.

The heat exchanger contains a package of perforated plates 1 with tubular flat coils 2 between them. The ends of the coils 2 are located around the perimeter of the plates 1 of the bag with the formation of sealing gaskets 3. The heat exchanger contains collectors for supplying 4 and 5 of the working space of the annulus and is equipped with nozzles 6 and 7 connected to the end sections of the coils 2, which are cylindrical, one of nozzles 6 or 7 of each coil 2 has a choke hole 8.

The heat exchanger operates as follows.

One of the working media passes through the flat coils 2 and exchanges heat with another medium, which exchanges the plates 1 and the coils 2 from the outside. This medium is served and

is removed from the heat exchanger through the manifolds 4 and 5.

The expansion of the pipes 6 and 7 of the coils 2, protruding beyond the ends of the heat-exchanging plates 1, is cylindrical, which makes testing simple and easy to collect, since the soldering or welding is carried out by simple, well-known methods.

Making the throttle hole 8 in the wall of the cylindrical nozzles 6 or 7 of the coil 2 allows for the manufacture of coils with flat contact surfaces and cylindrical protruding ends at a constant pressure of the filler in the coil and its punching on a vertical press.

The invention allows to intensify heat exchange, increase compactness and simplify the heat exchanger technology.
