Ok I had an idea... Yesterday while I was taking processors off of motherboards.... I found a rather normal looking heat sink. and droped it on my hat. By now you have probably figured it out that I have a messy room and I want to make a cool(ing) hat. So I am thinking of running a little pump (very little) and fan off of 1-2 9v batteries. Some Kind of coolant (water) and a couple of prototypes And I will have a cooling hat.... (YES PEOPLE I REALIZE ITS WINTER!!! (where I live)) Any ideas ?

My project I would like to complete is a thermoelectric piece of turbo piping to cool on my friends drift car it needs to be able to run on a 12v battery .I am looking at buying a few of these http://www.allelectronics.com/make-a-store/item/pjt-7/40mm-x-44mm-thermoelectric-cooler/1.html building a square piece of turbo piping to put it in. I am still not quite sure exactly how it works. I am a Ford Technician, Ford uses them in the heated and cooled seats so they kinda explained how they work but they left quite a bit out. So a lil info or suggestions would be appreciated thanks. If I build it I'll be sure and put the build up on here.

I'm using a laptop-sized, vented, inverted vegetable tray to keep the laptop cool. It's quite effective even without any fans in this scorching heat. I added a CPU fan underneath ( 12 V, 0.42 A), and ran it off a USB cable from the laptop. The air is quite nice, but one thing I'm a bit worried is, when I touch the top of the laptop, it slightly vibrates constantly due to the fan underneath. Is that dangerous for the laptop? I'm planning to add another fan beneath the hard disk. The one I have now, is under the laptop's CPU fan. Another thing I would like to know is that, is it okay to run two fans of 042 A each, from two USB ports? Each USB port can supply 0.5 A max current. Running one fan off each port should be okay? But, today, the temperature was quite high in the afternoon, nearly 50 degrees! I'm thinking of buyin a readymade laptop cooler. One of these three cheap ones at ebay India: http://cgi.ebay.in/Folding-Chill-Pad-Stand-Laptop-Cooler-Cooling-2-Fan-/250631119144?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item3a5ac76128 http://cgi.ebay.in/Chill-Pad-Stand-Laptop-Cooler-3-Fans-USB-Fan-LED-Light-/250629679857?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item3a5ab16af1#shId http://cgi.ebay.in/New-Super-Mini-2-Fan-Foldable-Laptop-Cooling-Cooler-Pad-/280504780978?cmd=ViewItem&pt;=LH_DefaultDomain_203&hash;=item414f6348b2 Please advise / comment.

Here is the thing. I'm going on a 5 day trip and I'm taking a cool box with me. A cool box will only stay cold for half a day with ice in it. Compressed gas becomes cold when it expands, but buying cans of whatever gas and releasing them in the box is wasteful and expensive. Air out of the bicycle pump is kind of cold, but not near cold enough. How can I decrease the temperature coming out of the nozzle ? Or does someone have a better idea on how to turn muscle power into cool drinks.

Any idea's of keeping our troops cool in Iraq? Temperature rises to 100's during the day. Seems our government only has more cumbersome vests with (the lightest) cooling motors of 6 pounds and from what I gather can only be used in a vehicle.

I bought a 110 Victorian home in Middle Georgia and was studying about installing underground piping to help cool the house. Has anyone experimented with 5 inch PVC before underground to cool with? I took a study of temps in the house, attic and crawl-space to see if I pulled air from the crawl space, I could use that cool air to help circulate in the house to assist cooling. I found that the crawl-space was actually as close to the outside temp. It wouldn't help. I then studied using piping to put under ground about 3 feet and use a to-and-from push fans then tie it into the fan-only central heat and air system. I then wonderered if I would cause a positive preasure issue. I haven't tested it yet, but I think the ground temp is about 68 degrees constant if you go at least 3 feet deep! Any comments?

Question by vivekgade | last reply
So I'm completely new to water cooling, I own a closed loop cooler and I know the names of the water cooling parts and assembly, but I have no real experience. I presume it's possible to use a normal radiator as a passive radiator in a loop, but I've got a couple of questions. First, do I have to be worried about what the radiator and waterblocks are made of, are the metals important? Second, will I need a significantly more powerful pump than the standard D5? Thanks! P.S. the rad I had in mind is this http://www.screwfix.com/p/flomasta-type-11-single-panel-single-convector-radiator-white-300-x-800mm/38602 It's rated for 1505 BTU/hour, which equates to 441W, which is in theory plenty my PC (4670K, HD7850 which I'll probably upgrade in the near future) The reason for using this kind of radiator is because they're far cheaper and passive, although I suppose the increase in pump power may negate quietness of no fans. It's also more fun ;)

Question by fmmarc56 | last reply
I'm building a power supply for my cnc machine that gives off about 37volts at 8 amps, and 12 volts at 0.9 amps. All of the transformers are from radioshack (using 6 heavy duty, 25.2volts, 2 amps transformers, 4 in parallel giving off 25.2 vdc at 8 amps, and 2 12.6 volts in parallel. Together in series gives about 37 volts at 8 amps. using 1 25.2 volts 450mA transformer, center tapped) My case does not have enough room for proper cooling such as fans. My case is water tight though, should I fill it up with something like mineral oil to keep the transformers cool?
Topic by guyfrom7up | last reply
Normally I'm pretty good with electronics, but I need some help with this problem. I'm building a power supply for a cnc machine and I need help designing a circuit to power fans when it's over a certain temperature. Here's some things it needs: 1) 12 volts supply (easy with a transformer and filtering it) 2) power fans when it reaches a certain temperature. 3) still keeps the fans on even though the rest of the system is off. 4) after the system if off and it's down to temperature then the transformer turns off, to save electricity and to not make it hot after a long time. If possible can someone draw up a schematic? Thanks in advance!

Hi, my name is Michael and I'm from Austria. Nowadays we have about 38°C (100°F). We have a Terrace which has a area of 33m² (355.21ft²). This terrace has a roof, which consists of polycarbonate plates. We have the problem that it is very hot on our terrace although we use awnings. Now I've discovered some ideas how i could cool down our terrace. The first one could be a water cycle, with a container and a pump. Then the pump could pump up the water. The water flows down the roof and flows back into the container. I don't know if this is a efficient way to cool down our terrace? The 2nd possibility I discovered is water mist. I found this video to show the principle: http://youtu.be/bYTcMCm2zWg I don't know if it is possible to sit underneath the water mist without getting wet?? I just want some Ideas and oppinions. Maybe some of you have realized their own cooling system? I know how to program an Arduino and other microcontrollers and I am able to develop electronic circuits. So I think i have the basic knowledge for building such a system, but I can't decide which principle i should use? I am sorry for my bad english skills, but i hope that you can understand me. Thanks in advance Mike

So I'm going to be making a full-body space armour type costume (Samus from Metroid Prime) eventually and I want to try to design an active cooling system that isn't too heavy, can be concealed within the costume, doesn't require too much replacing of coolant , and doesn't use obscene amounts of energy. I know the way it's done in commercial active cooling vests is that they run ice water through plastic tubes in a vest. The problem with this is that there is a big, huge tank of water with a big pump that the vest is tethered to and it needs to be plugged into an outlet. The way I'm thinking of doing it is by putting a network of copper wires in the garment I'll be wearing under the armour that lead to a cooling system in the back of the suit that, right now, I'm thinking will involve ice packs and/or a fan array. I feel like it might not work, so the alternative is to design a custom water or liquid cooling system. I'm planning on using lithium ion batteries for the cooling system and lights if I can. Any ideas or suggestions?

I have my workshop building i am trying to cool without spending a 1000.00 bucks. I havea small chest freezer forget the cubic feet but it is around 2 ft. by 3ft. in size. I was wondering if i fill 75 5 full of water and instal a coil of 100 feet of 3/8 copper tubing in a coil on the inside running to a 36 inch fan with 75 ft of 3/8 coil on the front and set it to pump 32 degree water to the fan . Do you think this woudl bring a 10ft by 16 ft building down from 100 to 80 degrees ? This would probably be cheaper on electricity over all than a a/c if i could afford one. Can anyone share there thoughts? Thanks alot Andy

I am trying to design a heating system for an animal incubator that can be transported in a car to rescue animals and keep their body temperature level. I was thinking of using the peltier systems to heat the box the animals will be staying in but I'm not sure if they would have the capability of 70-90 degrees fahrenheit. Also the temperature needs to be very specific (plus or minus 1 degree) is there a thermometer out there that would work well for this? I just need some help on learning about these because I've done a little research but I'm still confused on how they work and if I could even use them. Also, is there a good website to buy these on? I could use a lot of little ones or one medium sized one (up to 1ft by 1ft) but not too tall.

Using these ideas as a starting point:http://en.wikipedia.org/wiki/Icy_Ballhttp://en.wikipedia.org/wiki/Einstein_refrigeratorhttp://en.wikipedia.org/wiki/Gas-absorption_refrigerator"Another variant uses air, water, and a salt solution. Warm air is passed through a sprayed solution of salt water. The spray absorbs humidity from the air. The air is then passed through an evaporative cooler. Humidity is removed from the cooled air with another spray of salt solution. The salt solution is regenerated by heating it under low pressure, causing water to evaporate. The water evaporated from the salt solution is recondensed, and rerouted back to the evaporative cooler."Directions on how to make an icy ball.

I have an older computer, and i was thinking instead of buying a new fan and installing as an out-take, what if i just reverse the one fan i have to pull air out, instead of running two fans.. would this cause overheating or any other problems, or would it provide better airflow in a "vacuum" effect for the computer. i only have the one fan in it right now.
Question by bradburyk | last reply
Well, I seen the instructable to submerge a PC motherboard in non-conductive mineral oil to cool it and brainstormed that this could be the perfect fix for my RROD problem with a early model Elite. I have drawn up plans and already found a few problems and would like some input on them. I do not expect a expert answer but I'm sure there are people out there that can make a far better assessment on this than I. 1.) Will the oil conduct and move enough heat to be more effective than fans? 2.) The case I have designed requires roughly 2.8-3.0 Gal of mineral oil and if i was to consider circulating it through a radiator, what would an appropriate pump size be? ( gallons or liters per min) 3.) Also I would plan on using only wireless controllers so is there a way to solder some leads onto the sync button and maybe to an external momentary switch so I would not need access to the MB everytime we wanted to add another player? Thank you for any help you can provide on any of these issues. Regardless I will begin work on it tomorrow as a experiment and to challenge myself. I will be making an instructable on this when it is done. And many thanks to the original author that inspired me to take it a step further. https://www.instructables.com/id/Mineral-Oil-Submerged-PC/

Its so hot and... well.... I made a device to cool myself down! I might make an instructable, but basically, I took two 20oz bottles with caps, poked 2 holes in the top of one, 1 hole in the other. I then ran tubing between the two, and in the bottle with 2 holes, I added a bit of tubing to put the air intake below water level. I filled the 2'holer up with icewater, and blew a bit on the air intake to get it started. It works very well, to say the least! :P

Is a possible way to super cool a gas (nitrogen or oxygen) to liquid temperatures by using a sub-zero tank of 5000 psi compressed air to blast that gas over a radiator and therefore cool the gas in the radiator to a liquid, then quickly pump it to a chilled high pressure insulated tank.
