High-temperature cylindrical stainless steel/sodium heat pipe was manufactured and tested under long-term operation. The container material was stainless steel 316L and the working fluid was sodium. The heat pipe was 25.4 mm in diameter and 1000 mm in length with a two-layer screen mesh wick. The evaporator part was 600 mm and the condenser part was 300 mm in length. Total measurement points on heat pipe were 15 points and 12 points were located in condenser part. The heat pipe was heated for 142 days(3400 hours) at 800℃ In the test period, the maximum temperature difference was increased from 18℃ to 28℃ and the maximum thermal resistance was as low as 0.01 5℃ V.

To enhance isothermal characteristics of a glass-forming surface, a rectangular parallelepiped heat pipes<br/> were fabricated, tested, and analyzed. The working fluid was sodium and the wall material was stainless steel<br/> 304. The dimension of the heat pipe was 210(L)×140(W)×92(H)mm. Screen mesh was inserted to promote<br/> return of working fluid. The bottom side of heat pipe was heated electrically and the top side was cooled by<br/> liquid circulation. The temperature distribution at the bottom side was of major concern and was monitored to<br/> determine isothermal characteristics. The operating mode of sodium heat pipe was affected by the temperature<br/> of cooling zone, input heat flux, and the operating temperature of heat pipe. The heat pipe operated in a<br/> normal fashion as long as the heat flux, was over 5.78W/㎡, and the inside temperature of condenser part<br/> was above 95℃. The maximum temperature difference at the bottom surface was observed to be 32℃ when<br/> the operating temperature of the heat pipe was around 500℃.
