The invention relates to the field of energy and may find application in heat exchangers of the type of air cooler (AVO) of gas.

In the General case, the air cooling unit is a device consisting of two main parts: surface cooling (heat transfer section) and the system air supply.

Known heat exchanger type air cooler gas containing heat transfer section, secured in the tube sheets, with cameras inlet and outlet of the coolant, the fan drive and the base metal (RU 2075714).

Known heat exchangers of the type of air cooler with horizontal heat exchange sections of the injection type, in which the fan is located to the coil in the direction of movement of the air (EN 2200907). Heat exchangers of this type are more simple and convenient in maintenance, but occupy large areas and are more bulky and consume a lot of energy.

The closest analogue to the technical essence and the achieved result of the claimed device is a heat exchanger type air cooling natural gas to the collectors of the input and output of product AUG-75(100)used for cooling the gas at compressor stations of main gas pipelines (see Webcounter, the.Bessonniy and other Fundamentals of calculation and design of heat exchanger for air cooling. C/P: Nedra, 1996, p.84-85, RIS). Heat exchanger type air cooler gas consists of horizontal sections of the collector type, collected from bimetallic finned tubes, which are blown by the air flow injected from the bottom axial fans with drives from low-speed motors. Heat transfer section include chamber inlet and outlet of the refrigerant gas containing the tube plate with holes, into which are sealed the ends of the finned heat exchange tubes. The material of heat exchanger tubes: internal - steel fins - aluminum.

The disadvantages of the known heat exchangers of the type AVO are high power consumption, a significant intensity and complexity of manufacturing, which makes them expensive to manufacture and operate. The long pipes and large dimensions and weight of the apparatus as a whole lead to a large consumption of material. Considerably higher power consumption of the fan drive due to the high aerodynamic resistance of the air when it travels through the bundle of heat exchange tubes. In addition, the air, rolling on the tube bundle, has a non-uniform velocity field that does not effectively use the entire heat exchange surface. The bottom of the aja speed heated air at the outlet of the heat exchange sections may cause recirculation, that is, the reverse current of the air flow in the rarefaction zone on the suction side of the fan, and hence energy loss. To a significant loss of power for moving fluid (cooled natural gas pipes also causes the increase of the hydraulic resistance of the gas distribution pipes beam from the camera to its supply. The individual units of the heat exchange apparatus of the type AVO, namely manifolds, inlet and outlet gas pipe cameras and the actual beam finned heat exchange tubes under pressure leads to excessive loads on structures located in areas of high pressure, and additional hydraulic losses associated with non-uniformity of the gas flow supplied to the cooling. Work in aggressive environments also requires the use of AVO corrosion-resistant materials that ensure its performance under these conditions.
