聚光型真空集热管在太阳热水器中的应用

聚光型真空集热管,是在真空管外管下方的内壁镀以反射镜面。这种内置的反射镜面,既具有太阳能热水器反射板提高阳光利用率的效果,又避免了外置反射板积雪、积垢、增大风阻的弊端,其成本更得以大幅下降。应用聚光型真空集热管的热管式太阳热水器,由于采用了大直径外管,通过内置反射镜面的聚光作用,所用热管的数量大大减少,从而降低了热管式太阳热水器的产品成本,市场前景广阔,值得推广。

THow to use reflexible and focusing evacuated tubes at solar water heater

reflexible and focusing evacuated tube is a type of All-glass evacuated tube,there is a aluminium plating on the inner surface of external tube.The inner plating can reflect sunlight, snow and dirt cann’t be remained and the reflected configuration’s cost become lower.Reflexible and focusing evacuated tube can be used in Solar Water Heater, the Heater transfer heat energy by water or by heat pipe.When the Heater transfer heat energy by water ,the reflexible and focusing evacuated tube can be inserted into water tank directly or joins water tank by tie-in,it lie on the diameter of the reflexible and focusing evacuated tube because that make assembling to be possible or not. For reflecting and focusing , the reflexible and focusing evacuated tube is bigger and fewer, the solar water heater that use heat pipe cost lower, it is worth using and popularizing.
