Heat exchanger. High pressure atmospheric cryogenic evaporator.

Cryogenic, atmospheric, heat-exchange apparatus designed to heat or cool the working agent to a temperature close to the ambient air temperature. It is used in regasification units for conversion of liquefied gases into gaseous state, in refrigeration machines for cooling the working agent to the ambient air temperature. They are made of pipes with radiator shell or special finned pipes. Atmospheric heat-exchange apparatuses do not require additional energy impact on the process of heat exchange, it proceeds due to natural convection of atmospheric air in the apparatus
