CRYOGENIC LIQUID HEATING METHOD Russian patent published in 2014 - IPC F17C9/02 

FIELD: heating.

SUBSTANCE: invention relates to heat engineering and can be used for evaporation of media that are in a liquid state. The invention proposes a cryogenic liquid heating method consisting in passage of liquid through heat exchange elements with heat supply to them. A cryogenic liquid evaporator housing is made in the form of at least two two-layered covers, internal and external ones, so that an annular cavity for passage of heating heat carrier is formed. Each cover is made so that it consists of two shells rigidly attached to each other, between which channels for passage of a cryogenic component are formed, and which are combined into headers. Cryogenic liquid is supplied to an inner cavity of the internal cover from the header and discharged through a connection pipe installed in the central part of the internal cover. Cryogenic liquid is supplied to the inner cavity of the external cover from the header located on a convergent part of the external cover; at that, it is supplied so that filled channels are uniformly alternated with empty ones; with that, cryogenic liquid is passed through the whole cover; then, it is turned in the initial part of the cylindrical cover and returned to an outlet header located in the convergent part through the rest part of the channels.

EFFECT: simpler design, smaller dimensions and lower weight.
