solar heat pipe - RS-HP

I. Feature:

A perfect combination of the vacuum tube and the heat tube

1) high heat efficiency:

Advanced heat transferring style of the heat pipe, excellent selective absorptive coating and perfct combination with high vacuum heat prservation.

2) wide applicable ranger:

As the heat pipe has less heat capacity, it can be started qickly even under cloudy day and collect heat effectively. It can work normally even -30 celsius, as no water in the vacuum tube, it can effectively prvent lowing of the heat efficiency due to frost cracking.

3) each individual tube can work indpendently, and th whole machine can still work if any single tube was broken. And th service life of the heat pipe can be over 15 years.

4) the unique connection between the heat pipe nd th vacuum tube cn ensure both sealing nd glass vacuum tube avoid damage.

II. Principle of vacuum tube

The vacuum tube is composed of inner tube, outer tube, selective absorption layer, vacuum tube

space, inspiratory layer. We use the inner tube to store water. The outer wall os the inner tube

is the selective absorption layer. The space between outer tube and inner tube is the vacuum

space. At the bottom of the outer tube, there is a inspiratory layer which can be used to absorb

the remnant air.

Selective absorption layer transforms solar energy into heat energy, vacuum space can be

considered as the insulation to protect the heat energy from losing, inspiratory layer can absorb

the air which filters from atmosphere into the vacuum tubes.

III. Working principle of solar geyser

The vacuum tube absorb the sun’s rays and turn the rays into heat energy, heating the water

in the tubes. As the temperature of the water is rising, the density turns slightly, then the hot

water in the tubes floats into the tank. And the cold water in the tank goes down to the tubes.

Keeping natural cycling like this, the water in the tank will be heated.
