本発明は、ナトリウムを熱媒体としたヒートパイプに関

熱媒体の蒸発と凝縮のサイクルを繰り返すことによって
、パイプの片方から他の端へ熱の移動が行なわれる。Heat pipes are attracting attention as a device capable of transporting large amounts of heat. In short, a heat pipe is a closed container with a capillary wick that exhausts all non-condensable gases and seals in an evaporative liquid (heating medium). In a heat pipe, when one end of the heat pipe receives heat, the heat medium evaporates, moves to the other end, radiates heat, condenses back to the original liquid state, and is returned to the evaporation section by the capillary pressure of the wick.In this way, ,
Heat is transferred from one end of the pipe to the other by repeated cycles of evaporation and condensation of the heat carrier.

ための取扱いは容易ではない。In heat pipes, the type of heat medium enclosed is changed depending on the operating temperature. Among them, a heat pipe that uses sodium as a heat medium is one of the heat pipes that has excellent characteristics. However, since sodium is an active metal, it is highly reactive with oxygen, and handling for filling it into a heat pipe is not easy.

。Get rid of it! The purpose is to provide a moldy heat pipe. That is, one feature of the present invention is that, in a heat pipe using sodium as a heat medium, a metal body having a lower oxide formation free energy than sodium is incorporated into the heat pipe without contacting the heat pipe main body.

のナトリウムの純度ｔ−維持することができる。In a system where multiple metals exist, if there is a difference in the free energy of formation of their oxides, the oxidation reaction is dominated by the one with the lower free energy of oxide formation. In the case of sodium, the free energy of formation of N a 20 is 30
At 0°, 90K cal/acid volume 19 atoms, 100
00 to 165 Kaal/11 oxygen atoms. Therefore, in the present invention, a substance that forms an oxide having a free energy of formation lower than the free energy of formation of M&20 mentioned above is enclosed in the heat pipe together with sodium, thereby preventing the formation of an oxide of sodium and serving as a heating medium. The purity of sodium can be maintained.

The substance is attached to the heat pipe 1 as a spiral wire 3 as shown in FIG. 1, or as a wire mesh 4 as shown in FIG. M2. In addition, the first
, 2 indicates a wick, and 5 in FIG. 2 is a member that lifts the wire mesh 4 from the wall of the heat pipe device. In either case, in order to prevent corrosion due to contact between the active substance and the heat pipe body, the substance is attached to the heat pipe body so as to be suspended from the inner wall of the heat pipe. Moreover, the lid used for sodium as a heat medium is about 10 to 20% of the internal volume of the heat pipe.
