vacuum tube

vacuum tube 1.Absorbs faster than normal tube 2.high efficiency 3.It's made by copper,stainless steel,aluminum 4.Long life

All-glass double vacuum tubes, has excellent advantage of common glass vacuum tube and metal sealing-in vacuum tube. It's a new style all-glass evacuated solar collector tubes, which gives full play to feature of "vacuum tube gathers a hot tube ".

Name: All-Glass double vacuum tubesModel: KGV58Features: 1)fast start-up and response, it passes heat to water tank quickly. It can collect solar heat even in cloudy day. 2)It obtains high solar heat. 3)Hermetic seal in inner pipe. It can withstand high pressure. It can connect with system of tap water. 4)Water doesn't run in inner of double vacuum hot tube. 5)It stands against freeze weather. 6)it keeps warm for 24 hours.

7)Available size: 47mmX1500mm, 58mmX1800mm

8)Materials of tubes:copper,stainless steel,aluminum.

The heat transmission process of all glass double vacuum sun collection heat pipe includes 4 links:

1). In the heated end of the heat pipe: the working liquid in the pipe gets its source of heat from the outside; it begins to evaporate after it has the ability of evaporation latent heat.

2).The steam begins to move to refrigeration End as a result of differential pressures between the Heating and refrigeration End in the pipe.

3).In the Refrigeration End, the evaporation latent heat released from the pipe is taken by the outside cold medium, The evaporation condensed to liquid under the role of gravity, and then return to evaporation end.

4).The condensed liquid is reheated and becomes evaporate under the role of floating liquid core and then to resume the same movement.
