supply DMG tube solar collector for split solar system  

The DMG tube collector is mainly composed of vacuum tube heat pipe and manifold. Also, the exhalation part of the heat - absorption wing of the vacuum tube heat pipe i s placed in the one side of is connected by the advanced metal connection technique. The glass tube is extracted high vacuum degree. The part which put out the pipeline of condensation part can meet the liquid of the main pipe of the manifold by the linker. So the heat can be passed by convection.

During work hours, the heat absorption wing with selective absorption coat will take in sunlight, then, pass it to the condensation part to change the heat transfer medium of the heat pipe. In this way, the liquid will be changed into solid, then move up to the condensation part. The heat exchange can be made through the liquid which come from the linker and the main pipeline of the manifold. After the exchange, the heat exchange medium will cool into liquid from solid, then back to the exhalation part. According to this circulation, the temperature of the main pipeline of the manifold will be raised and commute again with the medium of the tank under the compulsive circulation. The water temperature will be raised under this way.

DMG tube collector bears the following advantages:

High heat efficient, can work all year long, advanced heat exchange method. The favorable sun selective absorption coating and high vacuum heat preservation condition is the guarantee of the system working with high efficient.

Heat capacitance is small, while the startup is quick. It can be started up to output energy within two minutes. The highest smolder temperature can up to 250.

It uses the heat exchange medium to transfer the heat. Further, there is no water in the vacuum tube. These two measures prevent channel jam and power output failure from forming furring, settling bedload. It can still operate in the event of occasional tube breakages. It is convenient to fix and maintain.

Antifreezing, Hail Impact Resistance: the high performance of the heat-pipe energy exchanging method ensure the system still can be worked in the thirty degrees below zero centigrade, and can resist the impact of the hails whose diameter is less than 25mm.

High vacuum degree: the heat-absorption wing is packed in the Boro-silicate glass tube which vacuum can reach 5*10^-3Pa, and even worked in the moist area, it can also without any corrosion.

Endure the high pressure: the hot water system can endure 0.6PA, so it can be connected to the city regular water system directly, and work under the pressure
