Safety heat exchanger for variety of fluids

摘要

The sec. chamber (10) of a first heat exchanger is firmly connected to the prim. chamber (8) of a second heat exchanger (4) for formation of a safety chamber (10,8) which is under vacuum and is partly filled with a fluid (14). In the space above the fluid corresp. to the vapour pressure curve of the filled fluid is filled vapour. The vapour chambers of the sec. chamber of the first heat exchanger and of the prim. chamber of the second heat exchanger and also the fluid chambers of the sec. and prim. chambers are connected to one another.The prim. chamber (6) of the first heat exchanger (2) is flowed through by a first heat exchange medium (A) and the sec. chamber (12) of the sec. heat exchanger (4) is flowed through by a second heat exchange medium (B), with heat transport occurring via the safety chamber (10,8).
