目前市场上销售的真空玻璃管太阳能热水器，几乎全部都在真空管后面装有漫反射板．其作用是：充分利用真空玻璃管之间的阳光，将这部分阳光反射到真空玻璃管上，以提高水温Ｚ同时可减少来自热水器背部的风力影响，保护管子，减少热损失，提高热效率。真空玻璃管太阳能热水...
Currently on the market for the sale of vacuum glass solar water heaters, almost all behind the vacuum tube equipped with diffuse reflectors. Its role is: make full use of the sunlight between the vacuum glass tube, this part of the sunlight reflected to the vacuum glass tube to increase the water temperature Z while reducing the impact of wind from the back of the water heater to protect the pipe to reduce heat loss and improve thermal efficiency. Vacuum glass solar hot water ...
