The direct flow pipe collector is composed of two modules, one is direct flow vacuum tube and another one is manifold. The direct flow vacuum tube can also be called concentric double-pipe vacuum tube, which is made of glass tube, heat-absorb wing, direct flow pipe and metal cover. The work principle of this vacuum tube is as follows: The medium (like anti-freezing water or soft-water) in the system flows into the inner pipe which located in the manifold from the manifold inlet, then comes into the direct flow pipe along the inside pipe in the vacuum tube. In the vacuum tube, the heat-absorb wing with the selective absorption layer will transfer the absorption energy to the system medium according to the metal medium, then the heated system medium flows out through the clearance between the direct flow pipe and the inside pipe, and exchange the energy with the medium (water) in the water tank, so the temperature of the water in the tank will be up.
Key specifications/special features of direct flow tube collector:
The medium and the direct flow pipe exchanges the energy directly, so the heat collecting effectiveness is very high, and the performance can not be attenuated
Because of the forced circulation of medium, you can disposal the collector tube conveniently
Compare to the heat pipe collector, you can get a high collecting effectiveness no matter you install it horizontally or vertically
It can solve the installation problem for the high-stairs effectively
Outer tank: Alnico 2.0mm
Manifold: 3/4-inch
ISO9001 and CE certification
