all-glass evacuated collector tube

基本解释

These solar thermal parameters of all-glass evacuated collector tube were adopted by China national standard GB/T 17049-1997.
上述全玻璃真空太阳集热管的光热性能参数已经被国家标准《全玻璃真空太阳集热管》（GB/T 170 49- 1997）采用。
The average thermal efficiency determined is around 80%in the 25 60℃ for single all- glass evacuated collector tube with aluminium diffuse reflector.
探讨与确定了单根全玻璃真空集热管在其背后采用铝漫反射板，温度在25—60℃范围内的平均集热效率，约80％。
The vacuum degree between the inner and cover glass tubes plays a very important role in heat loss and the life time of all-glass evacuated collector tube.
全玻璃真空太阳集热管内外玻璃管夹层间真空度的保持情况对有效降低热损、提高太阳能的利用率、延长集热管的寿命都有至关重要的作用。
