Balcony type collector with U pipe
Balcony type collector with U pipe is fit for the hot water system on balcony, U shape mater pipe is put into the glass vacuum tube, the tube absorb the sun energy , the medium in U shape pipe absorb the heat and transfer the heat to the water. Balconytype collector with U pipe is the same as the collector with heat pipe, the glass tube isn't touching the liquid heated,and a spot of heat is missing and working medium is with high temperature. Because the liquid is heated in glass tube, the heat can be transformed directly. Also, this type collector can be installed horizontally, and the frame is simple, the installation area is reduced, and Avoid collector influencing architecture appearance.
1.vacuum tube adopts vacuum magnetron sputtering film coating technology, absorptivity is 95%±2,
emissivity is 4%±2, Daily average thermal efficiency is ηd≥75％。
2.copper pipe for water, ultrasonic cleaning, ultrasonic welding.
3.there is no water in the tube, it can work under the temperature with -35℃
4.the system adopts rigid connection and can stand the high pressure.
