FIELD: power engineering, particularly gas cooling plant components. ^ SUBSTANCE: gas inlet or outlet chamber is made as a high-pressure tank and comprises side, upper, lower and end walls. Gas inlet or outlet chamber also comprises not less than two load-bearing partitions arranged between side walls and provided with through orifices. One chamber wall is made as tube plate with orifices defining grid structure and adapted to receive heat-exchanging tube ends. One chamber wall has orifices to receive pies to connect thereof with gas inlet or outlet manifold, which supplies gas to or discharges gas from the chamber. Orifices for connection pipe receiving, load-bearing partition orifices and tube plate orifices define communication system to connect gas air cooling plant with gas pipeline. The communication system has several stages with orifices formed so that orifice number at each stage successively changes in gas flow direction. For gas inlet chamber above number increases, for gas outlet chamber the number decreases. ^ EFFECT: possibility to equalize velocity field, reduced hydraulic hammer, which results in reduced power losses in pipeline conveying gas to be cooled and in increased thermal performance of air cooling plant as a whole or air cooling plant section, increased economy of plant production and operation. ^ 3 dwg, 13 cl |
