aluminum can solar heater: 5 steps (with pictures)

by:AAG     2020-11-05
That\'s how I made an aluminum tank solar heater!
Easy-to-hold cans, beer cans, soda cans, any aluminum cans you can save, save them!
Collect these supplies once you have saved a pile of aluminum cans: black paint (high heat)
Mine is for the grill.
High heat and leakage prevention agent/gluewood (I used 1x4\'s)
, A piece of plywood 1/4 thick, used for insulation of foam back panel, or other foam/insulation, drillwood ironing panel, plexiglass or tempered glass panel. Please be careful with this step! ! !
Remove all pop labels from the jar and rinse off any remaining soda or liquid from the jar to dry them.
Drilling carefully (
I drilled 3 holes at the bottom of each jar, which is the largest drill I have).
This is to get the air through the jar.
I\'m just trying to keep the jar stable and drill it under a little pressure to keep it from flying.
Once you have drilled holes in all the jars, you can start stacking them together and fixing them with hot caulking or glue.
* You can add as many rows of cans as you like, as long as they are placed in the \"box\" you will build.
I determined my \"box\" size with a tempered glass, which is from the old T. v. stand.
It\'s 24 \"x 42\"
I have a piece of plywood 1/4 thick and I use it to make the back of the box.
Then I cut my 1x4 and put it on the edge of the plywood to make a frame a little larger than the glass.
Note: * heat can be maintained as long as the sun can reach ordinary glass, tempered glass, or even organic glass, and is thick enough.
Heat preservation of a foam board (
I got my laying from the former owner of our house and I also used some parts of the pool noodles)
And cut according to the size to fit the back and sides of the box.
Seal all holes and edges with your high-heat cauldron.
When drying, spray foam insulation using high temperature matte black paint.
Next, I took another 1x4 board and used a big hole drill, mine was 1.
5 inch, drill as many tanks as you have in the middle of the plate.
For example, if you have 5 rows of cans, you drill 5 holes in the middle of the board.
Connect this board (
I use wooden screws)
Level is about 3 inch from the bottom of your box.
Fill all edges and/or gaps.
We hope it\'s air. tight!
Then I used the same drill bit to punch a larger hole in the middle of my box bottom plate (see photos).
I do this by overlapping the holes made by my number 1.
5 inch bit.
This is for more air to come in.
I repeated the process of the top plate of my box.
This is to let the air out. (
There will be more information about this in a minute! )
Now you can add a row of your jars.
Simply arrange them, match the holes on the board you just drilled, and fix them in place using a high temperature caulking or glue.
I added some extra caulking on the back of the jar to help them stay stable.
Now you can paint everything in the box with high temperature matte black paint.
Try to get around all the corners, corners and gaps.
After drying, you can connect the glass to the top of the box using high temperature glue.
Be sure to make a seal.
We want this to be air. tight!
* Due to the heavy weight of the tempered glass, I had to tie a fitness around it to bring about strengthening it to keep it in place.
If I do it again, I will use the plexiglass or make a recessed box to keep the glass better.
Still, it works well in the end!
* How does it work: when you put the solar heater in the sun, it heats up to about 160 degrees even on cool days.
My solar heater was only in the sun for a few minutes before it actually started heating.
It\'s also fun to watch and measure heat.
I measure my body temperature with a meat thermometer.
Only about 50 degrees outside.
When the cold air enters the hole at the bottom of the box, it is heated by black jars and glass that absorb the heat of the sun.
The matte black paint is very dark, so it will attract the sun.
The holes in the tank produce a turbine effect, and when the air in the tank passes through each tank, it rotates the air in the tank.
The warm air rises naturally, so it becomes a bit Warner when the air passes through each jar.
Finally, when the air flows out of the top hole of the box, you can feel the warmth!
* Note: Make sure the box is tilted a bit (
I put my back in the chair)
So that cold air can enter from the bottom of the box.
Also, make sure your box is facing the sun; )
