FIELD: heating.
SUBSTANCE: invention relates to nuclear power engineering, namely, to heat exchangers incorporated with passive heat removal systems intended for nuclear power plants. The proposed heat exchanger comprises the chamber, hear exchange pipe bundle arranged in the duct receiving cooling medium fed from below, and hear carrier drain circuit. Vapour feed branch pipe is connected to the said chamber, the branch pipe outlet being arranged above the heat exchange pipes ends. Note here that outlets of the said pipes are immersed in condensate.
EFFECT: simple design, higher reliability, lower weight and cost, and reduced metal input.
