Heat pipe Description:
1. Heat-pipe conduction, no water inside, thus it is successfully prevented from the defects of tube block and low power output caused by water fouling and deposits of mud and sand. 2. It prevents the tube from being easily broken caused by the volume expansion when the water in tube freezes in frigid season. 3. Start up quickly. Energy inside the tube can be taken out within 2 minutes under sunshine. The stagnation temperature of the heat-pipe can reach 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 5x10-3Pa of vacuum, so it cannot be corroded event in moist area. 6. It perfectly solves the fetal defect of the common all-glass vacuum tube solar water heater, which can not run if one of the tube is out of work. Heat Pipe Evacuated Tube The heat pipe evacuated tube consists of the glass evacuated tube and a copper heat pipe installed within the tube. The copper heat pipe transmits heat to its tip which is plugged into the collectors heat transfer manifold. As water runs through the manifold heat is transferred from the copper heat pipe to the water. The heat pipe transfers the heat to the manifold by a very simple method. The copper heat pipe is hollow and contains acetone. The hollow centre of the heat pipe is a vacuum, so that at even a temperature of around 40 ℃ the acetone will vaporize(boil). The vapor rises to the tip(condenser) of the heat pipe where the heat is transferred to the water flowing through the manifold. The loss of heat causes the vapor to condense and flow back down the heat pipe where the process is once again repeated. This method of heat transfer is thousands of times more efficient than a solid copper rod. Heat is therefore very efficiently transferred from the glass evacuated tube to the water.
Solar Heat Collecting panels (modules) are designed to meet increasing requirements of building aesthetics, high efficiency and working with system pressure. They can be widely used, such as individual residence, large hot water project.Solar Heat Collecting panels can be easily assembled together and used for Residential Hot Water Center, Central Heating, swimming Pool Heating, Space heating, Industrial heating Process, Air Conditioning etc.
Collecting panels benefits from the joint technology of the heat pipes and the vacuum tubes, so that They enjoys not only the advantages of both the vacuum tube and the heat pipe, but also those created through their joint.

The solar collector is designed to be used with pressure up to 8 bar/116psi. This means it is compatible with all low pressure, and most mains pressure domestic hot water systems. In closed loop or sealed (dead water) thermal store systems an expansion vessel is often used to prevent pressure buildup as the water expands. A pressure release valve should also be used as a safety backup.
