Copper Header Pipe
The JinYi solar collector's header is designed
to providing excellent heat transfer and corrosion resistance while
using a simple"plug in" installation method.
The key features are as follows
1. Heat pipe ports provide simple plug in
installation while still ensuring tight contact with the heat pipes
for optimal heat transfer. Thermal heat conduction grease is
applied to the heat pipes condenser prior to insertion to further
enhance heat transfer. Given the high temperatures that the
manifold is exposed to, the expansion of the heat pipe condenser
and "setting" of the heat conduction paste results in the heat pipe
being firmly held in place. This ensures excellent heat transfer
for the life of the solar collector. As the heat pipe is extremely
reliable and durable, there is no need to ever remove or replace
the heat pipe, even if changing a solar tube.
2. The header pipes are molded to match the shape of the heat pipe
ports in order to maximise contact area. In addition, the heat pipe
ports are brazed to the header pipes providing a direct metallic
connection.
3. The "contoured" header pipe design produces turbulent water flow
enhancing heat transfer.
4. The header pipes are brazed using red copper, Copper header:
0.8mm, length:1700mm, lead free brazing rods, which are suitable
for potable water and provide a strong, quality joint.
5. Available in rear port or end port inlet/outlet
configuration.
6. 8mm ID copper temperatures sensor ports at both the inlet and
outlet which are brazed directly to the header pipe for accurate
temperature measurements.
Rock wool insulation layer
Rock wool is a very popular insulation material,
used throughout the world in many high temperature insulation
applications. Rock wool is also non-flammable, and so an excellent
choice for a high temperature solar thermal solar collector. One
key advantage of rock wool is that it can be molded into any shape.
Via a process similar to baking a cake, the rock wool is "cooked"
at high temperatures matching perfectly the shape of the header and
the heat-pipe vacuum tubes.
