FIELD: the invention refers to energy engineering namely to air cooling apparatus applied particularly for cooling of natural gas. ^ SUBSTANCE: the cooling apparatus has ventilators for feeding of exterior cooling environment predominantly of air into the body of the apparatus and at least two heat exchanging sections with chambers of input and output of cooling gas. Single-passing finned heat exchanging tubes located in the section in rows according to its height and forming a bundle are packed into the tube plates. Each chamber of input and each chamber of output has from two to seven sockets for joining to the collector of input or output of gas which are connected with a gas pipe line. The total square of the transversal section in the light of the group of the heat exchanging tubes of the bundle communicated along the flow of the cooling gas preferably to the nearest to them the feeding socket, exceeds in 1,2-1,7 times the square of the transversal section of this socket in the zone of contiguity of the last to the chamber of input of gas into the heat exchanging section of the apparatus. At that the tubes of the bundle of the section are taken in at condition according to which the ratio of the square of the interior heat exchanging surface of the tubes to the total volume of in-tube space is determined with the coefficient that makes up (98-412) [ m-1]. ^ EFFECT: increases economy of the air cooling apparatus as at manufacturing so as at exploiting due to decreasing metal consumption and labor-consuming at manufacturing and also decreasing of energy consumption at simultaneous increasing of reliability and improving maintainability of the construction. ^ 18 cl, 11 dwg |
