pipe working theory
Heat pipes is not are new concept, it
is earliest used in aviation area, in aircraft scientist use this heat pipe to transfer
high temperature, to keep the temperature balance and keep the aircraft safe.
Now heat pipe is commonly used in computer and air-conditioning
area. Laptop computers usually use small heat pipe to conduct heat away from
the CPU, and in air-conditioning area, people use heat pipe for heat conduction.
As we know, at sea level water’s boiling point is 100 oC, but
when you are on the top of a high mountain which level is very higher than the
sea level, then the water’s boiling point will less than 100 oC,
water will boil such as at 60 oC(The high level the lower boiling
point), so it is why people must use pressure cooker to cook food on the top of
high mountain or altiplanoHeat pipe just take use of this principle of water
boiling at a lower temperature with decreased air pressure, we evacuated the
heat pipe and fill a little volume purified water inside, so make the purified
water under evacuated situation, so water can boil only on 30oC.
When vacuum tube absorb solar energy and heat the heat pipe to 30oC,
the water vaporizes and rise to the top of the heat pipe condensor, when heat pipe condensor meet cold water and
cool down, the water will fluidify and return to the bottom of the heat pipe,
so once and once again to repeat this process.
