NATURAL GAS LIQUEFACTION DEVICE AND METHOD OF DESIGNING A NATURAL GAS LIQUEFACTION DEVICE Russian patent published in 2020 - IPC F25J5/00 

FIELD: heat exchange.

SUBSTANCE: invention relates to production of air-cooled heat exchanger for natural gas liquefaction device. Proposed device comprises multiple heat exchangers (2) with air cooling arranged to cool down the fluid to be cooled, in natural gas liquefaction device (1), arranged on top surface of structure (6). Of the plurality of heat exchangers (2), at least those heat exchangers (2), which are arranged along the surface of structure (6), on which blows the wind (W), comprise a heat exchanger with a large pressure drop, which is capable of providing supply of cooling air with a given air flow rate at a given design pressure drop in range of 200 Pa to 1,000 Pa of pressure drop of cooling air before and after passing through the tube bundle, which is a bundle of pipes, which enable to cool the flow of fluid medium.

EFFECT: providing supply of cooling air with preset flow rate, which is adjusted for design pressure drop, which excludes weather influence and ensures stable ability of cooling of fluid medium to be cooled.
