Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, in the embodiment of the present invention, a nuclear power plant main control cooling room is provided, including a wall 1 and an interlayer 2 arranged inside the wall 1 and used for heat conduction; wherein,

[0024] The wall body 1 is made of metal material so as to conduct heat quickly;

[0025] The interlayer 2 is made of a phase-change heat storage material within a certain range of melting point, so as to start heat storage when the room temperature is higher than the melting point of the phase-change heat storage material, and the phase-change heat storage material should have low cost, stable performance, Large heat storage capacity and other advantages.

[0026] In one embodiment, according to the actual needs of the p...

Abstract

The invention provides a nuclear power plant master control heat dissipation chamber, which comprises a wall and an interlayer that is disposed in the wall to conduct heat. Specifically, the wall is made of a metal material, and the interlayer is made of a phase change heat storage material within certain melting point range. The nuclear power plant master control heat dissipation chamber providedby the invention can overcome the problems of low heat storage capacity, and little heat storage and the like of concrete in the prior art, and is suitable for marine environment.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for a main control room of a nuclear power plant, in particular to a heat dissipation room for a main control room of a nuclear power plant. Background technique [0002] The main control room is the control core of a nuclear power plant. Under a hypothetical accident, keeping the temperature of the main control room at a suitable temperature and prolonging the residence time of personnel in the main control room are essential design requirements for nuclear power plants. [0003] In the prior art, concrete is installed on the walls and ceiling of the main control room to form the main passive heat sink for heat dissipation. At the same time, in order to further enhance the heat absorption capacity of the ceiling of the main control room, a metal mesh is installed on the surface of the concrete ceiling. Grid, and a metal photosensitive plate is installed on the metal grid, so as to increa...
