Personal Portable Spot Cooler

Here a smaller version of from my last version of air conditioner.
do check it out its really cool and TRENDY
haha its really portable all you need to do is charge and go.
because the ice stored in it will last and stay frozen with only a fraction of melting for hours! then just pop it out. and turn it on.Its really great and super portable anywhere everywhere.
So far this is the coolest! haha..
DONT underestimate this thing.. it produces up to 108CFMs under only 7.2v that will blow you down for 2 straight hours. that is 50mins for cool and rest for fan LOL. haha hope you guys will like this. thanks for the figure! you know who you are.

Step 1: Getting parts and CUTTING!

Heres what you need,
styrofoam board,a firm container, any battery source(rechargeables..go green!)
a pc case fan some cardboard and some time.
First, insulate the container by having walls of the styrofoam at all sides. all you need is Cut here and there and finally place a thin layer of plastic to contain water and make it leak proof.

i like your idea. thanks for sharing this.

[sharadholani]

How to attach the fan to it? how to give it support?

[Dipankar]

Very cool man, Why didn't I think of this before, but the name is misleading it is an air cooler and not an air conditioner.

[eyeintheskyakagod]

anything which changes the state of the air whether that be temperature or humidity is conditining that air so i am sorry to say but it is an air CONDITIONER

[farhanians]

Ouh yah shure will rename it. hah btw im afraid that ppl will mistake for an air cooler. AIR COOLER . i think this is like more of a spot cooler.. spot air cooler heh but if you still find it as an air cooler, im okay

[Dipankar]

Yeh.....Personal spot cooler is more like it.

[farhanians]

yeah thanks! gonna rename it .. PERSONAL SPOT COOLER hahas thanks

[jovenhatsjr]

Can you kindly show how is it wired, i mean the power from batteries , am really poor in electricity but i really love the innovation. I've tried to make one but the batteries is becoming increasingly hot as i switch on .

[68autobug]

it sounds like you are shorting a battery or batteries which will overheat the batteries...
make sure you have all the positive+ terminals red wires hooked together

and all the negative- black wires hooked together

just connect up to the fan...  if the fan blows the wrong way
just reverse the wires to the fan....

You can place a switch in either wire...  just cut a wire and connect to a switch... so the power goes thru the switch....

I have a 1968 VW beetle without air con...
this looks like a sure way to keep it cool during the summer months...

cheers

Electronics only draw the power in amperages they need. A car battery would not hurt the fan at all. You could hook a fan like this up to 400 car batteries wired in parallel and nothing fancy would happen other than that fan would be going for a long time. If you wired up 400 car batteries in series, you would definitely obliterate the fan. So yes.

[devilmaycry]

Yeah right!!! i had xbox360 2 in 1 fan and i hooked it up with 2 x 18 v batteries and suddenly the fans exploded and the smoke came out!

[tinstructable]

Wired in series, or parallel? You probably over-volted it. 12v is the normal rating for fans like that, so 1 18v battery probably destroyed it. I am right, go look it up.

[Electroinnovation]

haha well i should try hooking up a car battery to my air conditioner...i used an old rc car motor LOL

[terrilein]

I'm totally oblivious to the electronics aspect. Can someone please explain to/show me how the fan is attached to the batteries???

[ashashank]

couldnt 1 simply use a cellphone charger to power the fan?

[ashashank]

couldnt 1 simply use a cellphone charger to power the fan?

[marcusm73]

how about adding salt to the ice water to drop the temp even more.

[Moonlight27]

I agree...

[wingl]

This seems like a great project. A possibility is to wire it to power off a USB port. Any possibility to explain how this could be done?

[Electroinnovation]

yea thats easy just get an old usb cable and cut it open. I would test the wires to see which is the positive and negetive because i forget. the 3 volts from a usb cable would be enough to power it but it would not be very powerful.

[jvan0907]

Could it be wired to 5v eg usb 500 mah?

[ducktape100]

what kind of box are you youing

[nutsandbolts_64]

doubles as a swamp cooler lol

[icedude007]

Nice instructable (: I'm going to try this and power it with a usb port. Knowing your in singapore was helpful as it also gets very humid here in Hong Kong. Thanks man (:

[the dudemaster]

you know if you changed the innards up a bit it might work better. . . i would try this but i just don't have the time before i go on vacation. . . just take a food can (after using the food and washing the can out would probably be preferable) and drill some holes in it below the preferred ice level and put it directly below the fan and seal any gaps . . . .this would probably work better with just ice instead of ice water. . . i don't know if it would work but if anyone could find the time to try it it wouldn't hurt. . .

[mikemmcmeans]

pc fans move alot of air at low pressure (opposite of an air compressor) the fan would not be able to push enough air under the water

[endolith]

Put copper pipes in the ice water for the air to flow through, like a radiator

[checho5123]

 Hey man one question, which method works better, using the radiator like u did in the big one or just using the cold air that the watter gives off?? i know the small one probably cools less because of the size but which method works better overall??

[Pretty Idiot Productions]

This is great.. I think i'm gonna use the freezable ice packs in the cooler instead of ice and water. When they thaw out, i'll just throw them back in the freezer and switch 'em with new ones.

[Bridel568]

dude drop the 1.5v just use 2 or 3 9v`s they make rechargeable 1s but I don't know were to get them. but wow! the fan really has a kick. I got the tip of my finger in it(it really hurt) but thankfully it wasn't my whole finger. yes it maybe a 12v fan but I connected 2 new 9v`s and a used 9v and man does this cool you off it might make ur acp work better

[farhanians]

hahas. yah 9volts will do. but mines 7.2volts. hehes still having the kick!
lol but 2x9v= DISASTER 18volts hahs

[68autobug]

Use 9 Volt batteries in Parallel so its still 9 volts..
the more You use the longer they will last...
and rechargeable ones would be excellent...

just have all the Positive+ terminals hooked together
and all the Negative- terminals together
all equals 9 VOLTS...

Lee   VK2LEE

[ReCreate]

i once over powered it with about 60 Volts worth of 9V batteries before XD

[junits15]

try putting some dry ice in it it will be alot cooler and last alot longer it is realy cheap if u know where to look!

[nolte919]

soooooo... where do you look for cheap dry ice? Inquiring minds want to know.

[Zaphod Beeblebrox]

i seed it at grocereys storeses sometimeses........

[junits15]

well that really depends on where u live and your local laws ect. ANYWAY you have to try and find a local distributer near you because dry ice costs ALOT more when shipped, because you have to pay for the dry ice that subliminates while being shipped. (the ice that turns into a gas during shipping has to be paied extra for)and sometime gas dirstributers will sell it, because dry ice's only ingredient is co2. and usually the cost of dry ice is somewere between $1-2 per pound.

[hughscott5]

You should check local super markets, I used to work at one and they usually have it on hand in case of a power outage, to keep the frozen food from going bad. The one near me sells it for $1 per pound. If you do use dry ice, make sure you are in a well ventilated room. As junits15 said it's just co2, too much of it can cause oxygen to displace, which can lead to sickness or even suffocation. You should be OK with a window open and a fan blowing. Great Instructable by the way!!
