43、态凝结为液态，在 重力作用下，又回到蒸发段，继续吸热汽化。如此周而复始，将热量不断的由热 流体传给冷流体。如下图所示：3、3、热管的特点：金属、非金属材料本身的导热率取决于材料的导热系数、温度梯度，以 金银为例，其值为415w/m*k,经测定，热管的导热系数是银的几百倍甚至上千 倍，故热管有超导体之称。经过热管换热器进行交换的两种换热介质，中间由一块管板隔开，换热介质各走各的通道，运行中即使有个别换热管损坏，也不会造 成两种换热介质相混，不必停车堵漏，因此，热管换热设备具有使用周期长、安 全可靠的优点。4、应用：热管可以更高效的将热量提取出来，现代工业可以利用热管回收废烟气、 热水中的热量，再
