Cans for Solar Air Heater

[MaN1aC666]

easy simple and great ! i did one ... but you got it way more simple then what i did !

i'll do it like you next time Thx

The idea is that a vortex naturally reduces resistance to flow, and helps raise the velocity of flow around the outer periphery, exchanging heat better

[Olegserov2]

More resistance for air flow only. It will not effect heat transfer ability. If, keep air more cold inside the can than you have a chance to increase heat flow from the can wall to inside of can air. So, the idea is useless.

The first part is okay

I do it my self but the 2nd is not.

The alu heats up and must be transported to air. Why make it hard for the cane to do so?

Great thinking!

Now T H A T is the best I have seen so far for the bottom, Super concept !!

I have about Mmm 300 cans with the tops removed (Swing-away) Brand hand driven geared can opener,

Can tops vary, Coke are the hardest to remove but not bad, Pepsi and local beverage cans seem easier, regardless its an easy thing and with this chisel concept, well looks like I have my work cut out for me (Pun intended) HA HA HA

Hi I got to say I love this idea. Was wondering if anyone has done any testing to as just how many cans should be done like this in a column. My concern would be causing too much resistance for the air. What do you guys think?

You have to have a very sharp chisel. and know how to sharped the chisel after it gets dull. When I cut thur the can the tip of the chisel cuts first on the outside curved part of the can and then cuts more into the center of the can. This way you are not trying to cut to much can at once. I use a 3/4" chisel. It took me some time and practice but after a few hundred cans you get really fast at it.

I have tried this repleatedly and every time I buckle the can. Whats the trick? Thanks

[vpbubbies]

@md50md You must be a Canuk??? (I am) I too buckle the cans every time, hard to even hold an empty can without denting it, and forget about drilling out the bottom, for when apply even a little bit of downward pressure, the can buckle or even twist around, resulting in yet another ruined can. Frustrating to say the least. I too await any suggestions to get around this problem. Do they have thicker aluminum cans in the USA???

Dam Good idea easy to see what you are doing great job

I live in the southeast and made a modified pannel based on this idea...i used cans to create a baffle behind a piece of galvalum roofing painted black to slow the air flow and give the air more time to heat ...my pannel is 32in by 72inches...with a 2 inch space behind the pannel for airflow...im able to heat a 16x20 insulated shop ..temperture increase 60 to 80 dgrs...im considering using a small solar fan like you can buy at an autoparts store to exhaust heat from your car in the summer

I have a fan on my panel (about 100 cmf) and it pushes the air though. I get a 120 Degrees breeze from it when the sun is shining and it is 20 degrees outside. I hope to post more pics and vids soon.

Yes, I have made and installed a 4'x 8' panel on my house. I works.

That's a great way to do the fins. Have you made a panel yet?
