FIELD: process engineering.
SUBSTANCE: invention relates to power plant engineering and may be used in production of air cooling apparatus section chambers. Tube plate with heat transfer perforations, top, bottom and lateral walls welded together to make housing are produced. Note here that said top, bottom and lateral wall are furnished with ledge that makes flange on housing outer side surface on rear wall side. Tube plate ends fitted in perforations, steel membrane is fitted on housing face rear wall. Said membrane is 2-3 mm-thick. Said membrane is welded along perimeter to make closed chamber with said housing. Rear wall is arranged in contact with membrane and screwed to housing. Screws are fitted in threaded holes made in housing rear wall and flange.
EFFECT: ease of fabrication and servicing, higher reliability and longer life.
