solar vacuum tube with the heat pipe,new tri-element vacuum tube
1.wide applicable range:as the heat pipe has less heat capacity,it can be started quickly even under cloudy fine day and collect heat effiectively.It can effectively prevent lowing of heat efficiency due to frost cracking or sacling.
 2.the unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube.
3.each individual tube can work independently,and the whole machine can still work if individual tube is damaged.The senice life of the heat pipe can be longer than *5 years.
4.Higher heat efficiency:advanced heat transfering style of the heat pipe,excellent selective absorb coating and perfect combination with high vacuum heat
