Characteristics
A perfect combination of the vacuum tube and the heat pipe.
1) Higher heat efficiency:advanced heat transferring style of the heat pipe,excellent selective absorb coating and perfect combination with high vacuum heat preservation
2)Wide applicable range:as the heat pipe has the less heat feature,it can be started quickly even under cloudy day and collect heat effectively.It can work normally even below **0 degree.As no water in the tube,it can effectively prevent low heat efficiecy due to frost cracking or scaling.
3) Each tube can work independently,and the whole system can still work even if one tube is damaged.The service life of the heat pipe can be longer than *5 years.
4) The unique connection between the heat pipe and the vacuum tube can ensure both sealing and easy to replace the damaged glass vacuum tube.
Structure and Principle of Heat PipeThe heat pipe is hollow with the space inside evacuated, much
the same as the solar tube. In this case insulation is not the
goal, but rather to alter the state of the liquid inside. Inside
the heat pipe is a small quantity of purified water and some
special additives. At sea level water boils at **0oC (**2oF), but if you climb to the top of a
mountain the boiling temperature will be less that **0oC (**2oF). This is due to the difference in
air pressure.
Based on this principle of water boiling at a lower temperature
with decreased air pressure, by evacuating the heat pipe, we can
achieve the same result. The heat pipes used in AP solar collectors
have a boiling point of only *0oC (*6oF). So when the heat pipe is heated
above *0oC (*6oF) the water vaporizes. This va pour
rapidly rises to the top of the heat pipe transferring heat. As the
heat is lost at the condenser (top), the va pour condenses to form
a liquid (water) and returns to the bottom of the heat pipe to once
again repeat the process.
At room temperature the water forms a small ball, much like mercury
does when poured out on a flat surface at room temperature. When
the heat pipe is shaken, the ball of water can be heard rattling
inside. Although it is just water, it sounds like a piece of metal
rattling inside.
This explanation makes heat pipes sound very simple. A hollow
copper pipe with a little bit of water inside, and the air sucked
out! Correct, but in order to achieve this result more than *0
manufacturing procedures are required and with strict quality
control.
