Description

one

The invention relates to refrigeration technology.

The purpose of the invention is to intensify heat exchange and reduce metal intensity.

Fig, 1 shows the proposed capacitor, a general view; in FIG. 2 a part of the separating partition; FIG. 3 is a section A-A in FIG. 1,

The condenser of the refrigerating machine contains a shell 1, tube bundle 2 installed in it, separating partitions 3 placed in the annular space, made in the form of corrugated strips with perforation 4 and installed with a gap of 5 relative to each other along the tube bundle. The corrugation pitch is equal to the pipe pitch, and the corrugation height H varies along the length of the separating partition 3, Perforation 4 has a selection of 0.88435 .2

Items 6 are directed to the extruded tube rows.

The condenser works in the following way.

5 The refrigerant vapor enters the condenser and is condensed on the tubes of the beam 2. The forming fluid is drained from the tubes onto the separating partitions. Moving downwards along the surface of the corrugation, the liquid flows around the flange 6j without filling the perforation 4, intended to pass the unfused condensable part of the refrigerant vapor to the downstream

5; -p dam bundle tubes 2, the channels of the corrugations of the separating partitions 3 have a slope due to the difference in height of the corrugations H, and Hj at different ends of the partition. Move along bumps in

20 the slope side, the condensate is drained into the downstream rows of the beam through the gaps 5.
