And radiated by metal wall, so as to have contact area big, the advantages that easily cooling, overcome concrete in the prior art
It is low to there is heat storage capacity, the problems such as amount of stored heat is few, and marine environment can be applied to.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid
Put, obtaining other accompanying drawings according to these accompanying drawings still falls within category of the present utility model.
Fig. 1 is the cross section structural representation for the nuclear power station master control heat dissipation chamber that the utility model embodiment provides.
Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
As shown in figure 1, in the utility model embodiment, there is provided a kind of nuclear power station master control heat dissipation chamber, including wall 1 with
And it is arranged at the inside of wall 1 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 with the phase change heat storage material in certain melting range by being made, in order to which room temperature stores higher than phase transformation
Start accumulation of heat during the fusing point of hot material, and should to have low cost, stable performance, heat storage capacity big etc. excellent for the phase change heat storage material
Point.
In one embodiment, it is actually needed according to what master control room personnel resided, 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, its fusing point is 34 degree, density 1440
kg/m3And heat of solution is 251kJ/kg；（2）NaSO3.10H2O, its fusing point is 32.4 degree, density is 1460 kg/m3It is and molten
Antipyretic is 251kJ/kg；（3）NaSO3.10H2O, its fusing point is 29.5 degree, density is 1680 kg/m3And heat of solution is
