Abstract: FIELD: the invention is designed for application in energy engineering namely in the technology of manufacturing and  construction of heat exchanging sections of a gas air cooling apparatus. 
     SUBSTANCE: the mode of manufacturing of a heat exchanging section of a gas air cooling apparatus  includes  manufacturing predominantly on a loft of the lateral walls of the frame of the 
     section with wall displacers-cowls of air environment, assembling on a slip with support poles of the elements of the frame of the section - lateral walls, lower transversal beams and gas input-output chambers forming gables of the frame and also of frame rigidity elements with the following packing of the multi-row bundle with single-passing finned heat exchanging tubes with forming with them  and the gas input-output chambers  of a vessel working under pressure, installation of upper transversal beams and carrying out  hydraulic tests of the assembled section. At that the terminal poles of the slip are executed with locating  their leaning  sites at different levels with height difference  making ( 1,1-4,6)d, where d - an interior diameter of a tube of the bundle and at assembling the frame  the gas input-output chambers are installed on the final poles of the slip. 
     The heat exchanging section of the gas air cooling apparatus is fabricated in accord with above indicated mode. The mode of manufacturing of the heat exchanging section of the gas air cooling apparatus includes manufacturing on the loft of the lateral walls of the frame of the section with wall dispersers-cowls of air environment, and also  elements of rigidity of the  frame, assembling on the loft with support poles of the elements of the frame - lateral walls , lower transversal beams and forming gables of the walls of the frame of the chambers of input-output of the gas and also of the elements of rigidity of the frame with following packing of the multi-row bundle out of single-passing finned heat exchanging tubes forming with their help  and the gas input-output chambers of a vessel working under pressure, installation of upper transversal beams and carrying out of hydraulic tests of the assembled section. At that the low and the upper transversal beams of the frame of the section are installed along the length of the lateral walls with spacing overall of height marks, equal (0,12-),51)d, where d - an interior diameter  of the tube of the bundle and cuts of different height predominantly for dimensions of the transversal section of the chambers are made for  installation of gas input-output chambers on the final plots of the lateral walls in the upper belt and the overall part of the height  of the walls. The heat exchanging section of the gas air cooling apparatus is characterized with the fact that it is manufactured in accord with  this mode. 
     EFFECT: allows to increase manufacturability of fabricating  of the heat exchanging sections at simultaneous lowering  of metal consuming of construction, simplification of the process of fabricating and lowering labor-intensiveness.
