|Super Stirling Engine Fan
This fan was designed to be a
real workhorse. Every effort was made to reduce friction to an absolute
minimum while at the same time making the unit extremely reliable,
maintenance free, quiet and very long lived. My fan
has many hundreds of running hours on it while at shows and in my
office during summer months with no maintenance, service or repairs of
any kind done, or needed.
In addition to the crankshaft running in ball bearings, the power
piston rod is fitted with precision ball bearings. All of the
reciprocating parts use very low friction non-metallic components and
never need oiled. The hot cap is specially designed to absorb heat from
the flame. The carefully shaped and angled concave fan blades improve
the overall air moving efficiency.
The fan operates nicely on an alcohol flame only 1/4" diameter and
5/16" tall, moving a very respectable amount of air. During a day long
run, the displacer cylinder will never get more than just lukewarm warm.
One other design consideration was to make the fan an attractive piece
of machinery. You will be the judge of that!
The plans set consists of 9 sheets of drawings and 2 sheets of
construction and assembly notes.
