열원의 위치에 따른 평판형 히트파이프의 열적 성능

A series of experiments was conducted to examine characteristics of a grooved flat-strip heat pipe having multiple heat sources. The inner grooves of the heat pipe have the aspect ratio of 1 to 2.5(0.42×1.05 ㎜) whose pitch was 0.6 ㎜. Four block heaters (10×20 ㎜) were placed in the evaporator section at intervals of 20 ㎜ and six different heating modes were tested. The maximum surface heat flux of 80 W/㎠ was achieved while the operating temperature was kept below 100℃. In the nearest heating mode (from the condenser location), the heat pipe exhibited more stable temperature distribution than the far heating mode where the heaters is located furthest from the condenser.
