Proposed Air Cooling Tower

I am looking at making a cooling tower for one of my hot air model engine. The design will be as below, but I am wondering if anyone out there on the Forum has successfully made something like this that works.

Re: Robinson Hot Air Engine

That's quite a beautiful engine you have made Ian and I do like the radiator. I have just recently brought a computer radiator which suits a small fan and I will be looking forward to using it on a small power house like the one you have built. I must try and contact the two modelers you have mentio...

Re: Ltd engine?

Yes you can. If you look under utube SunPulse they give you the plans basically for doing it. I would expect it to be costly, especially the heating of the oil and or water.

Re: Ltd engine?

Hi Mr Scott
The size of an LTD engine you are speaking of would be around 2 to 3 mtrs Diameter. Here is a link for you to have a look at. It is Sunpulse Engine around 1.5kW at Tamera Village.

Re: Robinson Hot Air Engine

Know that feeling Ian (hee hee). Here are some pictures of the finished parts I did. I still need to finish the meths burner and fire box proper. Had to borrow a milling machine from my mate to make water channels in the main block and then screw on a top plate, Whew!!! That was a chore and many scr...

Re: Robinson Hot Air Engine

Pretty awesome. Certainly would be nice to have one of those. I made up the displacer and the regenerator and finally got it all together today. I ended up with a 20mm depth displacer and a 20mm stroke. Fired it up and away she went. Pretty good watching the linkage work. I will set up some pics aft...

Re: Robinson Hot Air Engine

Thanks Ian. Nice looking engines and I hope mine will look something of the same. I used a small milling machine from a neighbour to make a water channel through the top section and I might as well make a small water cooler on the bottom as well. After a lot of thought, I will go with an internal re...

Robinson Hot Air Engine

HI all I am in the process of making a Robinson Sterling engine with a piston diameter of 39mm and a stroke of 34mm giving me a 40.6CC volume. My displacer cylinder is 69mm internal diameter (stainless Steel). With a ratio of approx 1.6:1 the displacer cylinder has a stroke of 18mm which isn't much ...

Re: My First Rhombic Drive Engine

Hi Vjdeep Nice looking motor and well done. It appears that your piston and liner are both alloy - If this is so you will have an enormous amount of friction as alloy to alloy will gall and cause trouble to you. If you can change the liner to steel or cast iron. Ian knows a lot about this problems a...

Re: cold acceptor in cold head for cryocooler

Hi Ian & Yakka Reference to your observation of a person using the cold water from gas. I built a nice Beta motor for a friend just recently and we had all sorts of problems with the gas container going so cold that the motor would stop due to very little heat caused from bottle getting to cold and ...

Re: What type of Stirling Engine

Hi Mac I have made an LTD engine 14"Diameter using a large rubber diaphragm. Heating was done by solar hot water from a small homemade thermo heater. The water was pumped from the reservoir through copper tubing wound inside the displacer. I do not have the photos any more as the computer failed and...

Re: Burnt pancake displacer (carbon foam)

Another good use for that Bumkin would be to wrap the dough around the heater casing to prevent heat loss, especially when vertical heating from the bottom. This then would stop outside heat from going to the cooling end.
