Description

The invention relates to heat exchangers and can be used in the chemical ₅ petrochemical, food and other industries.

The aim of the invention is to reduce the hydraulic resistance during operation of the heat exchanger on highly viscous and vaporous media and increase its tightness, 1θ

FIG. 1 shows a plate of the proposed heat exchanger with a sealing gasket, general view; FIG. 2 is a section A-A in FIG. 1 (transition section with a seal 15 gasket between the collector holes and the corrugated surface of the plates); in fig. 3 is a section BB in FIG. 1 (transitional portion of a plate with a gasket); FIG. 4 - 20

longitudinal section of the transition section by stamping two adjacent plates in a compressed heat exchanger package, longitudinal section.

The folding plate heat exchanger contains a package of plates with a corrugated heat transfer surface! and collector holes 2 and 3 in the corners for the passage of working media, placed on the perimeter of the plates sealing gaskets 4 and 5. Between the collector holes 2, 3 and the corrugated heat transfer surface 1 are located the inlet and outlet sections 6, on which are made vyshtampovki 7, forming the channels 8 for the passage of working media. Installed on vyshtampovka 7 sealing gaskets 5 are made with holes for them, while their

sealing surfaces 9 and 10 are located on both sides of the stamps 7. Stamping 7 are located in increments of 20-30 5, where 5 is the plate thickness.

Sealing gaskets 5 are transformed into an upright gasket 4, sealing the corrugated heat transfer surface with communicating collector holes 2 and 3 connected with it,

The assembly of the plates into the apparatus package and its operation are carried out as follows.

Gaskets 4 are installed on the plate with sealing gaskets 5 around one of the pairs of collector holes, for example 2, and the other pair of collector holes 3 between the heat transfer surface 1 does not have gaskets 5, When compressing the adjacent plates into a package, sealing gaskets 5 installed on the stamps 7 , firmly held on to them, counteracting the pressure of the medium, due to the formation of a lock by contact of the stamping 7 and the reverse surface of the adjacent plate.

With this installation on the plate gasket 4 with gaskets 5, the working medium enters the heat transfer surface 1 and is discharged from it through the channels 8 and the collector holes 3. On the adjacent plate, the gaskets 5 are installed around the next pair of holes 3 and the working medium falls on the heat transfer surface 1 through the channels 8 of the holes 2.
