PROCESS HEAT EXCHANGER OF NUCLEAR POWER PLANT Russian patent published in 2009 - IPC F28D7/00 

FIELD: heating.

SUBSTANCE: invention relates to energy industry and can be used in purge systems of the first and second circuits of a nuclear power plant. A heat exchanger of a nuclear power plant comprises a tube bundle placed inside a vertical case and enclosed by a vertical housing. The lower section of the housing is connected to the lower grid of the tube bundle. The housing is set in respect to the case so that to form a vertical peripheral cavity which is divided into the upper and lower chambers by a baffle. A support of the tube bundle is set inside the case and connected to it. The baffle is made as a shell with its lower end being connected to the support and a band with one its edge being connected to the shell and the other one - to the case.
