This kind of tubes(closed tubes) have no water inside. it can survive high temperature even if thereis no water in the tank, and the glass tubes wont brake for the heat can only be transfured in one direction. This feature cannot be found in open tubes. the coating on inner tubes can sence any solar radiance as possible regardles that they are located in cold climate area.
Heat pipe vacuum tube solar collectors adopted the lastest INTERFERE COATING technology, which is more efficient than AL-N/AL coating technology. The selective coating on the inner tubes absorbs solar powder efficiently(absorption rate
