How Heat Transfer Works
Heat transfer occurs when there is a difference in temperature
between two mediums. Heat will travel from the hot source to the
cold source. The rate at which the heat transfer occurs at is
determined by many factors such as the heat conductivity of the two
materials andthe difference in temperatures of the two mediums.
Convectiuve heat transfer occurs when the materials are moving
against each other.
Plate heat exchangers have significantly good heat transfer rates
because they use metal plates which have high heat conductivity
rates and the plates are extremely thin. The plate heat exchangers
also achieve high amounts of heat transfer through convective
forces with both working fluids. With large temperature
differentials, great amounts of heat transfer can be achieved using
a plate heat exchanger.
Corrosion
Corrosion is usually how these units will fail. Use fluids with
reasonable pH levels to ensure a long lasting life. Hard water will
corrode faster than regular water. (Use distilled if possible;
Distilled should never corrode it) Salt water will corrode
stainless steel very fast. It is recommended to clean the exchanger
often if you are using corrosive fluids. Normal usage
(non-corrosive fluids) should expect 10-20 years of life. Fluids
containing chlorides will corrode the unit quickly.
Applications
This is an extremely popular unit for wood burning furnaces,
radiant floor systems, refrigerant systems, straight vegetable oil
conversions, beer chilling, air conditioning system and solar water
heating systems. It will work for any application in which the
desired result is for two fluids (liquid or gas) to exchange heat.
How it Works
Fluid A passes from the port on the left of the heat exchanger
through every other channel created by the plates to the opposite
end port on the left of the heat exchanger (looking at it the long
way). Fluid B passes from the port on the right through the other
channels created by the plates and comes out the other port on the
right side. The fluids are essentially touching each other through
the plates and heat is transferred from the hot fluid to the cold
fluid. (but the fluids do not mix)
