Description

The invention relates to heat exchange, specifically to plate heat exchangers. Plate heat exchangers are known that contain flat plates and a corrugated insert placed between them, forming working medium plates with plates, provided with end caps and connected to respective collectors. However, these heat exchangers are not characterized by a sufficiently high heat exchange rate. The purpose of the invention is to intensify heat transfer. This goal is achieved by the fact that between the plates and the insert there are installed parallel spacers placed perpendicular to the corrugation of the insert. FIG. 1 shows schematically the proposed heat exchanger; 2, the same cross-section. The heat exchanger contains flat plates 1 and a corrugated insert 2 placed between them, forming channels for working media 3 and 4 with plates 1, provided with ends of plugs .5 at the ends and connected to corresponding collectors 6–9, provided with supply and exhaust pipes 10–13 working media Between the plates 1 and the inset 2 are installed parallel spacers 14 placed perpendicular to the corrugations 15 of the insert 2, equipped with turbulizing inserts 16. At the edges, the heat exchanger is bounded by the side plates 17. The heat exchanger works as follows. One of the working media enters through the nozzle 10 and the collector 6 into the channels 3, passes through them, exchanging heat with another medium that enters the channels 4 through the nozzle 12 and the collector 8. The output of the working media is produced through the collectors 7 and 9. and nozzles 11 and 13. Due to the presence of gaskets 14 in the gaps between them, there is a periodic mixing of the flow of the medium, which flows through the channels of the same name, which allows to intensify the heat exchange. formula of the invention. A plate heat exchanger containing flat plates and a corrugated insert placed between them, forming channels for working renals with plates, fitted with end caps and connected to respective collectors, characterized by h ± o, parallel heat exchangers and inserts are installed between the plates and the insert. separator spacers placed perpendicular to the corrugation of the inserts.
