Among the figure: the 1-containment; The 2-pressure vessel; The 3-chimney; 4-evaporation ends heat pipe; 5-rising connecting pipe; 6-condensation end heat pipe; 7-one circuit pressure border; 8-vacuumizes quick access device; 9-vacuum monitoring system; 10-decline connecting pipe; The 11-connecting box.
Embodiment
Below in conjunction with the drawings and specific embodiments the containment of a kind of outside of the present invention with separate type air heat of cooling trap is further described.
As shown in Figure 1, a kind of outside of the present invention wherein comprises pressure vessel 2 and a circuit pressure border 7 etc. with the containment of separate type air heat of cooling trap in the containment 1.Containment 1 among the present invention namely can adopt prestressed concrete containment vessel, also can adopt steel containment vessel.
Be welded and fixed many evaporation ends heat pipes 4 around containment 1 outer wall, these evaporation ends heat pipes 4 are divided into some groups; The top exit of every group of evaporation ends heat pipe is communicated with the entrance that rises on the way connecting pipe 5, the outlet that rises connecting pipe 5 on this road is communicated with the top entrance of the one group of condensation end heat pipe that comprises many condensation end heat pipes 6, the outlet at bottom of this group condensation end heat pipe is communicated with the entrance of connecting pipe 10 on the way down, and the outlet of this road decline connecting pipe 10 is communicated with the bottom inlet of one group of evaporation ends heat pipe.The height of every group of condensation end heat pipe all is higher than the height of every group of evaporation ends heat pipe.
Every group of condensation end heat pipe all is arranged in the bottom of a chimney 3, and chimney 3 supports on the ground by bracing frame, and air freely passes through chimney from the bottom of chimney 3.Chimney 3 effects are to strengthen heat transfer free convection.Described chimney is called again air cooling tower.
Actuating medium flow through successively evaporation ends heat pipe 4, rising connecting pipe 5, condensation end heat pipe 6 and decline connecting pipe 10 return evaporation ends heat pipe 4 again, form closed waste heat and derive the loop.Actuating medium is water, methyl alcohol, ethanol, acetone or ammoniacal liquor.
On rising connecting pipe 5, arrange respectively and vacuumize quick access device 8 and vacuum monitoring system 9.Vacuumize quick access device 8 and be quick coupling device, be at ordinary times the self sealss state, with the time can carry out vacuum pumping by quick external vacuum pump.The vacuum tightness of vacuum monitoring system 9 in can the on-line monitoring pipeline if vacuum tightness reduces, produces inconduc, just by vacuumizing the incondensable gas in the quick access device 8 extraction pipelines, to keep the cooling power of system in the pipeline.
The quantity of above-mentioned many evaporation ends heat pipes 4 or many condensation end heat pipes 6 can be at 500～50000, specifically determine according to the waste heat of reactor core, the waste heat that the reactor core that many evaporation ends heat pipes 4 are carried produces equates with many condensation end heat pipes 6 heat that the air cooling is carried in chimney, satisfies the requirement of Core cooling.
The entrance of all condensation end heat pipes 6 that above-mentioned every group of condensation end heat pipe comprises can collect in the same connecting box, and the entrance of this connecting box is communicated with the outlet that rises on the way connecting pipe 5; The outlet of all condensation end heat pipes 6 that this group condensation end heat pipe comprises can collect in the same connecting box 11, and the outlet of this connecting box 11 is communicated with the entrance of connecting pipe 10 on the way down.
