Heat Pipe Vacuum Tube Characteristics
1) Higher heat efficiency:advanced heat transferring style of the heat pipe,excellent selective absorb coating and perfect combination with high vacuum heat preservation
2)Wide applicable range:as the heat pipe loss less heat feature,it can be started quickly even under cloudy day and collect heat effectively. It can work normally even below -30 degree.As no water in the tube,it can effectively prevent low heat efficiency due to frost cracking or scaling.
3) Each tube can work independently,and the whole system can still work even if one tube is damaged.The service life of the heat pipe can be longer than 15 years.
4) The unique connection between the heat pipe and the vacuum tube can ensure both sealing and easy to replace the damaged glass vacuum tube.
