以铜为主要壳体材料,纯水为工质,制作了双通道平板环路热管,并对其在不同方位下的传热特性进行了实验研究.研究结果表明,此双通道平板环路热管的蒸发器温度在功率变化中都可以迅速反应到相对稳定的值;其两个通道的传热特性基本一致;方位对蒸发器温度的影响在小功率时较大,大功率时变小;其在顺重力(水平且冷凝器在蒸发器上方)时的传热性能最好,蒸发器温度最低;若要求蒸发器温度低于90℃,各个方位都可以稳定传热360 W热量以上;冷凝管道尚未得到充分利用,此双通道平板环路热管的传热量还可更大.
Taking copper as the main shell material and pure water as the working fluid, a double-channel flat loop heat pipe was fabricated and its heat transfer characteristics under different azimuths were studied.The results show that this dual-channel plate loop heat pipe Of the evaporator temperature in the power changes can quickly react to a relatively stable value; the two channels of the heat transfer characteristics are basically the same; orientation of the evaporator temperature at low power larger, smaller at high power; its The heat transfer performance is best when the gravitational force (horizontal and the condenser is above the evaporator) and the evaporator temperature is the lowest; if the evaporator temperature is lower than 90 ° C, the heat transfer can be stable over 360 W in all directions; Have not yet been fully utilized, the heat capacity of the dual channel flat loop heat pipe can be even greater.
