Super Heat-Conducting Tube is consists of the glass tube and copper pipe. The temperature can be more 300 in the tube.
Features:
1) High heat effectiveness: higher than all glass evacuated solar collector tube by 15%.
2) heat pipes conduction: successfully prevents the defects of tube breakage and low power output caused by water fouling and deposits or dust and sand.
3) Prevents the tube from being easily broken caused by volume expansion when water freezes in the frigid season.
4) Low thermal capacity makes the tube start up quickly.
5) Energy output of sunshine within only 2 minutes.
6) Insulation temperature can reach 250, average heat efficiency can still be more than 50%; even under -50.
7) High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube has higher heat output in cloudy weather and in moist areas, especially in winter.
8) Solar collecting plate is sealed inside a high quality borosilicate glass tube with 5 x 10 - 3Pa of vacuum, to stop corrosion; even in moist conditions.
Metal-glass evacuated solar collector tube consists of a single glass tube and a flat or curved aluminum plate inside attached to a copper heat pipe.
1.All Glass Vacuated Tube
All glass evacuated tubes are the key component of solar collectors. The evacuated tube is similar to a conventional Dewar flask and consists of two borosilicate glass tubes, a glass with high chemical and thermal shock resistance. The outer side of the inner tube is coated with a sputtered solar selective surface. This coated inner tube is closed at one end and sealed at the other end to the outer tube. The annular space between the outer tube and inner tube is evacuated to virtually eliminate heat loss by conduction and convection.
We use the tubes which use the successfully developed innovative Advanced Solar Selective Coatings in commercial scale, which achieve the highest thermal efficiency and good thermal stability. Solar selective coatings absorb most solar radiation while simultaneously suppressing the thermal emittance loss from coating surfaces. They vary mainly in their optical property and thermal stability.
Excellent results have been obtained by using DC magnetron sputtering technology. A solar absorbance of 0.94 - 0.96 with an emittance of 0.04 - 0.06 at 100 centigrade has been achieved.

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:-35~300 degree celsius. As the 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 independently, 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 connection 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 anolized crust of manifold case use alumninum material of high strength with air flow design
1). Use super heat conduction pipe and has a good effect of heat exchange.
2). No water in the vacuum tube, so the tube will not break in the winter.
