Solar collectors
Theory of evacued tube with heat pipe solar collector
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 altiplano
Heat 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
condenser, when heat pipe condenser meet cold water
and cool down, the water will fluidity and return to the
bottom of the heat pipe, so once and
