Solar collector composed of vacuum tubes is good in pressure bearing, high efficiency and sanitation, the whole system can bear 0.6Mpa pressure, the whole system is operating under completely close circumstance. The water tank is equipped with electric heater, even if on cloudy or raining day, you can enjoy hot water. Sperate pressurized solar water heater takes advantage of high absorptance and low heat consumption of vacuum tubes to convert absorbed radiation into heat energy which is transferred rapidly to collector by heat pipe conductor, it can work effciently during four seasons. Advantages: 1, start fast 2, One-way heat transfer 3, high-usage 4,bear high pressure 5,good safety performance:no water in tubes, and if individual glass tube are broken due to outer force, it still can work normally. Working principle: There are Matching aluminium fin inserted to the vacuum tubes, leting the fin touch the inner pipe,inner pipe absorbs solar radiation and transfering the heat .When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically.The circulation pump makes heat-conducting liquid circulate automatically. the water vaporizes. This vapour rapidly rises to the top of the heat pipe transferring heat. As the heat is lost at the condenser (top), the vapour condenses to form a liquid (water) and returns to the bottom of the heat pipe to once again. the heat-conducting liquid transfers heat to water by heat exchanger in the tank. Collector (10TUBES) Frame: aluminun alloy Vacuum tube Heat pipe length:1700mm Four parts: evaporation section: Insulation section: Condenser length:65mm diameter:14mm wall thickness:0.8mm flow channel(mainfold) Main pipe and branch pipe is all made of copper. And connected by braze. the distance between two tubes is 70mm. the distance between one end of the channel and the first branch pipe is 115mm main pipe: diameter 35mm branch pipe:diameter:15.7mm length:74mm insulation of mainfold:rock wool
