Heat transfer principle
Heat pipe heat exchanger consists of six consecutive process:
a Endothermic--the working fluid is
heated by exhaust gas in the evaporator
section
b. Evaporation—The working fluid
evaporates. (in the shell , vacuum, Low
evaporation temperature)
c. Gaseous working fluid conveyor--- The
working fluid flow to condenser section
with the waste heat.
d. Condensing--Gaseous working fluid is condensed when it exposes to low temperature
shell wall.
e. Exothermic-- The working fluid releases a lot of heat when it is condensed and
the heat is taken away by the cold fluid.
f. The working fluid reflux-- after condensed, the working fluid is back to the evaporator
section by gravity or capillary pumping forces.
The six consecutive process carried out consecutively and the heat is continuous to
transfer.
Mechanical seal
a. seal by thread lock.
b. seal by O-ring.

2. Field of Application
-feed drying
-cereals and oil processing
-chemical industry
-air cooling after combustion process
3. Specification
Advantage:
-high heat recovery efficiency
-seldom temperature difference, fast heat starting, good isothermal
-the speciality of the heat pipe results in a high wall temperature, exhaust gas temperature
can be reduced without reaching the acid dew point, avoid the corrosion of the equipment.
-exhaust gas will not pollute air
Parameters:
Core tube material: copper, stainless steel, carbon steel
Fin material: aluminum, stainless steel
