DEVICE FOR COOLING FLUIDS AND DISTRIBUTOR THEREOF, INCORPORATING DEVICE ABOVE, AND METHOD TO STERILISE IT Russian patent published in 2009 - IPC F28D7/10 

FIELD: heat-and-mass transfer.

SUBSTANCE: invention relates to devices designed to cool fluids and distributor thereof, as well as to methods of clearing and sterilising such apparatuses. Proposed device comprises primary heat exchanger, secondary heat exchanger, 1^st pipeline for fluid to be cooled to circulate therein. It comprises heat carrier to transfer cooling power to fluid to be cooled that circulates in the 1^st pipeline. Note here that aforesaid primary and secondary heat exchangers are arranged, at least, partially, one into another. Note also that primary heat exchanger comprises the 2^nd pipeline that passes together with secondary heat exchanger 1^st pipeline and around it and along, at least, a portion of the length of aforesaid pipeline. The proposed device additionally comprises fluid source and, at least, one distributor valve. Note here that the said distributor incorporates a cooler implemented in compliance with one of the described versions. Proposed method of sterilising cooled fluid comprises the steps that follows, i.e. draining fluid from the chamber with primary heat exchanger heat carrier, or draining fluid from the 2^nd pipeline carrying primary heat exchanger hear carrier, draining fluid from the 1^st pipeline that carries fluid to be cooled and distributed, sterilising the 1^st pipeline during the period sufficient for killing bacteria and sterilising.

EFFECT: higher efficiency and simpler servicing.
