These attached drawings obtain other attached drawings and still fall within scope of the invention.
Fig. 1 is the cross section structure diagram of nuclear power station master control heat dissipation chamber provided in an embodiment of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
It is described in detail on step ground.
As shown in Figure 1, for a kind of nuclear power station master control heat dissipation chamber in the embodiment of the present invention, provided, including wall 1 and set
It is placed in 1 inside of wall and the interlayer 2 for conducting heat；Wherein,
Wall 1 is made by metal material, in order to which heat conduction is rapid；
Interlayer 2 is by having the phase change heat storage material in certain melting range to be made, in order to which room temperature is higher than phase-transition heat-storage material
Start accumulation of heat during the fusing point of material, and the phase change heat storage material should have many advantages, such as that at low cost, performance is stable, heat storage capacity is big.
In one embodiment, the actual needs resided according to master control room personnel, the fusing point of phase-change material should be 28 to 35
In the range of degree, and higher latent heat of melting and great proportion are needed, to save space.
Therefore, selecting suitable phase change heat storage material has：（1）NaCO3.10H2O, fusing point is 34 degree, density 1440
kg/m3And heat of solution is 251kJ/kg；（2）NaSO3.10H2O, fusing point is 32.4 degree, density is 1460 kg/m3It is and molten
