Abstract

A passive cold storage heat exchanger, comprising: a cooling room (1) to be cooled, a heat pipe assembly (4), a cold storage water tank (3), and a ventilation room (2). The ventilation room (2) is adjacent to the cooling room (1) and is separated therefrom by a floor slab (22); the ventilation room (2) is disposed above the cooling room (1); the heat pipe assembly (4) comprises at least two heat pipes (8) used for heat transfer; the heat pipes (8) are used for containing a liquid working medium (19); each heat pipe (8) comprises an evaporation section (5), a heat insulation section (6), and a condensation section (7) which are connected in sequence; the heat pipes (8) run through the floor slab (22) between the ventilation room (2) and the cooling room (1); the heat insulation sections (6) are disposed in the floor slab (22); the evaporation sections (5) are disposed in the cooling room (1); the condensation sections (7) are disposed in the cold storage water tank (3); the cold storage water tank (3) is used for introducing cooling water for cold storage of the liquid working medium (19) in the heat pipes (8); the cold storage water tank (3) is disposed in the ventilation room (2). By means of the passive cold storage heat exchanger, after losing all the power supplies inside and outside the nuclear power plant, the temperature of the cooling room can be maintained not to exceed a design value within a certain period of time only by means of water cold storage and passive heat transfer of the heat pipes.
