Abstract

Use: to increase the reliability and efficiency of heat exchangers. SUMMARY OF THE INVENTION: An additional thickened corrugated nozzle is mounted in a plate capacitor package at the ends of the channels. Its thickness exceeds the thickness of the material of the main nozzle. The distance in the channels between the inserts is 50-150 channel heights. 3 ill.

Description

The invention relates to plate-fin type heat exchangers and may find application in air separation plants using a deep cooling method.

The aim of the invention is to improve the quality of manufacture of the package, reliability, compactness.

In FIG. 1 shows a general view of the described package; in FIG. 2 - boiling channels; in FIG. 3 - condensation channels.

The package contains spacer sheets 1, bars 2, forming boiling channels 3 and condensation 4, in which the corrugated nozzle 5 and inserts 6 are installed, and strips of reinforcing nozzles 7 are installed at the inlet and outlet of the channels.

In a specific case, the package is made of a corrugated nozzle 6x2x0.2, where 6 mm is the height of the corrugation, 2 mm is the step of the corrugation, 0.2 mm is the thickness of the sheet.

In order to exclude the removal of channels, 50 mm wide strips of a reinforcing nozzle were introduced in the manufacture; 0.7 mm was selected from the condition of rigidity of the nozzle thickness. In order to maintain hydraulic resistance, the reinforcing nozzle is perforated, which ensures the explosion safety of the nozzle.

In addition, the reinforcing nozzle is involved in heat transfer. Strengthening the edges of the nozzle can significantly reduce the number of inserts, increasing the pitch between them to 50-150 channel heights, which significantly increases the heat transfer efficiency and reduces metal consumption, and eliminates wrinkling during manufacture. Expanding the range of 50 I 5 150 channel heights is inefficient.

A decrease in step I 50 leads to a reduction in the passage section of the channel, a decrease in the heat transfer surface, and an increase in metal consumption. An increase in step I 150 will necessitate a further increase in the thickness of the nozzle and, as a consequence, an increase in the metal consumption of the bag.

The package works as follows.

The boiling heat carrier is supplied to the boiling channel 3, and condensed to the condensation channel 4. In this case, the condensation heat is transferred through the baking sheet 1 to the heat exchange nozzle 5 of the boiling channel 3, where heat is effectively transferred to the boiling coolant. In general, the package provides a high heat exchange efficiency between the heat carriers.

The application of the invention allows to intensify heat transfer and increase the reliability of the structure and significantly reduce the weight of the bag.
