METHOD FOR COOLING GAS IN AIR COOLING APPARATUSES AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2021 - IPC F28D1/00 

FIELD: cooling.

SUBSTANCE: invention relates to methods for cooling gas in air cooling apparatuses and to apparatuses for implementation thereof. A method for air cooling of gas, including supplying gas into the pipes of a multi-row one-pass pipe bundle and supplying cooling air into the inter-pipe space, forming a zigzag pattern of air movement with high turbulence due to the outer finning of the pipe bundle containing finning elements placed equidistantly along the circumference, each formed by chutes put one into another, placed longitudinally on the pipe bundle, attached to the last one and to each other by the middle parts of the bases, and made on the side generatrices of the chutes with lobes deployed transversely in one direction or in a direction opposite to the adjacent lobes, arranged in longitudinal rows, the side generatrices of adjacent chutes are located in each element a distance from each other not exceeding the width of the lobes made along the entire height of the side generatrices and located in adjacent rows with mutual displacement, wherein, in addition to the zigzag translational motion, the cooling air is directed along channels formed by the spiral-shaped elements of the lobes, and swirled into a stable rotational motion relative to the axes radial relative to to the pipes. The outer finning of the heat exchange pipe, containing the finning elements in the form of a spatial Archimedes spiral, with the diameter of the spiral reducing when approaching the pipe, arranged equidistantly along a circumference.

EFFECT: increase in the efficiency of gas cooling in finned bundles of air cooling heat exchanger pipes of the above air cooling apparatuses; by swirling the cooling air in the channels formed by the spiral-shaped elements of the lobes, wherein the finning of the bundles of air cooling heat exchangers pipes is made in the form of said lobes in the radial direction relative to the pipes, leading to a significant increase in the contact time of the cooling air with the bundle of finned pipes, as well as a reduction in the static pressure of the cooling air due to the intensive swirling thereof contributing to a reduction in the temperature and, as a result, an effective reduction in the enthalpy of the cooling gas due to an increase in the heat transfer therefrom to the cooling air.
