Air-cooled heat exchangers of gas with an internal recirculation chamber of the type АВГ-СВР are designed to cool the gas after the 1st and 2nd stages of the compressor and oil in the lubrication system of compressors; units with capacity of 6,000 kW for gas-lift exploitation of oil wells. The vessel consists of two horizontal bays assembled of extruded bimetallic tubes. In the bays under the finned tubes there are coils of air heating. The bays are mounted on a supporting metal structure. Fans, one of which includes a mechanism for varying the angle of blades inclination with a pneumatic driver, while rotating in the manifold cavity, drifts the air through the tube side of the bays and thus cools the product.
