Heat 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 30^oC. When vacuum tube absorb solar energy and heat the heat pipe to 30^oC, 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.
