LIQUID-HEATED IMMERSION HEAT EXCHANGER WITH SPLIT DESIGN Russian patent published in 2024 - IPC F28D1/02 F28D7/12 F28F9/07 F28F13/18 

FIELD: heat engineering.

SUBSTANCE: used in contact heat exchangers for laboratory bioreactors of low volume. In an immersion heat exchanger for small-volume laboratory bioreactors, containing a contact heat exchange element made in the form of a body, a lid, inlet and outlet fittings, a body and a lid are made detachable with the possibility of connecting them with a threaded connection and the possibility of installing an extension insert between them using a threaded connection, the lid made with a flow extension with the possibility of increasing its length due to an insert attached to the extension using a threaded connection, and the contact surfaces of the body and the extension insert are made with a polished smooth surface that does not have hard-to-reach places.

EFFECT: ensuring the required temperature of the liquid medium in the biotechnological process.
