FIELD: the invention is designed for application in energy engineering and namely is used for manufacturing of heat exchanging equipment particular for gas air cooling apparatus. ^ SUBSTANCE: the mode of manufacturing of a tube chamber of the gas air cooling apparatus or a section of the gas air cooling apparatus fabrication of half-finished articles out of metallic sheet for lateral, upper, lower and butt-ends walls and for no less than two power bulkheads of the tube chamber with openings for passing of a gas flow. At that the length of the half-finished articles for lateral walls are fulfilled correspondingly the width of the apparatus or of the section of the apparatus. All half-finished articles are fabricated for the lateral walls with fulfilling chamfers for welding. At that at least the chamfers on the half-finished articles for the lateral walls forming the tube and the exterior plates of the chamber and also the chambers on upper and lower walls are fulfilled of broken configuration in the transversal section with forming support regions and edges of a welding mouth with a technological angle of opening-out 41-53°. After fabrication of half-finished articles an in series assembling and connection on welding of lateral walls with power bulkheads are executed and trough them a united rigid construction to which the upper and the lower walls are connected is formed. After that in one of the lateral wall forming a tube plate openings for the ends of the heat exchanging tubes openings are made and in the other lateral wall forming an exterior plate threading openings coaxial with the openings in the tube plate are fulfilled for providing possibilities of introduction of technological instruments for fixing the ends of the tubes in the tube plate and the subsequent installation of caps predominantly along the thread in the openings of the exterior plate and in the upper and/or in the upper walls openings for sleeves predominantly with flanges for connection with a collector of feeding or for offsetting of gas are fulfilled. At that the power bulkheads are installed in a high range making up ±1/4 of the high of the chamber counting from medium horizontal flatness along the height of the chamber, and the gables of the chamber are mounted after installation and fixing of the ends of the heat exchanging tubes of the chamber. ^ The tube chamber of the gas air cooling apparatus or the section of the gas air cooling apparatus, the gas input chamber of the gas air cooling apparatus or the section of the gas air cooling apparatus and the gas output chamber of the gas air cooling apparatus or of the section of the gas air cooling apparatus are manufactured in accord with the above indicated mode. ^ EFFECT: allows to decrease the labor-intensiveness of the mode, increase manufacturability of the measuring chambers and improve their strength characteristics and thermal efficiency. ^ 15 cl, 8 dwg |
