solar tubes

solar tubes:

Comprised of heat pipe, glass tube, heat-collector plate, aluminum safety-protection cap and getter, SHCMV tube has high practicability and reliability. Technology specialty: The tube has two technology patents in solar energy utilization. 1) The first patent technology: Glass-metal heat envelopment craftwork. Patent number: 79149 2) The second patent technology: Exhausting set for SHCMV tube. Patent number: 455502 Product specialty: 1) High heat effectiveness: Higher than normal all-glass tube by 10% 2) Heat-pipe conduction, no water inside, thus it is successfully prevented form the defects of tube blockage and low power output caused by water fouling and deposits or dust and sand 3) With small thermal capability, it can output power in 2 minutes. The highest temperature of cooling end can reach 250 degree centigrade. The average heat efficiency can still be 50% even under -50 degree centigrade 4) High efficient selective absorptive coatings and vacuum heat insulation technology ensure the tube to get higher heat output in cloudy weather and in moist area, especially in winter 5) Solar collecting plate is installed and sealed inside the tube of high-quality borosilicate glass with 5x10-2Pa of vacuum, so it cannot be corroded even in moist area 6) Hot water system can endure 0. 6MPa so that it can be connected to tap water tube Usage range: Able to be applied to big-scale hot water system, desaltification of seawater, industrial desiccation, hot supplication system, etc.
