High efficiency solar collector

solar collector Features: 1) Higher heat efficiency advanced heat transferring style of the heat pipe. excellent selective absorptive coating and perfect combination with high vacuum heat preservation. 2) Wide applicable range:-35 300degree celsius.asthe heat pipe has less heat capacity, it can be started quickly even under cloudy fine day and collect heat effectively.it can work normally even-35 below degree. As no water in the vacuum tube. it can effectively prevent lowing of heat efficiency due to frost cracking or scaling. 3) Each individual tube can work inidependently, and the whole machine can still work if individual tube is damaged. the service life of the heat pipe be longer than 15years. 4) The unique connectin between the heat pipe and the vacuum tube can ensure both sealing and replcace of damaged glass vacuum tube. 5) The insulating layer uses polyurethane bulk bubble and has a good effect of temperature preservation 6) Seamless and anolizedcrustof manifoldcase use alumninum material of high strength with air flow design.
