laptop cooler

My laptop gets really hot after about 30 minutes of Internet browsing and after 1 hour of gaming (I don't know why maybe because of the modem????) so I really need a cooler. I have three 1 or 2 inch (let me know if a need exact) fans I could use and wood legos knex and rokenbok. I have a hp pavilion dv6409us laptop with a 17.5 inch screen. if you need a picture of the bottom of the laptop so I can show you the hot spots and the fan let me know.

cajan cooler Answered

Hi everyone ., I am racking my brain out with with my latest projectand I dont have a pic of it yet but check this out ,I mounted a30"x30"large4core radiator to my 42" x 42" sop wall fan with a custom built wooden shroud about 10 ft high and ran 1/2" copper tubing down into a chest type deep freezer full of ice with a 5 gallon buckit of anti freeze and a 11 gallon per minute pump in it with about 30ft of 1/2" copper coiled in the bucket ,mounted to the discharge of the pump and circulated through the radiator and back into the freezer into the bucket continuasly then turned on the fan.. I THOUGHT IT WAS GOING TO KICK ASS Abut it did not and it slowed down the fans output by 50%. What did I do wrong ,DOES ANYONE KNOW.. PLEASE any info will be greatly apreciated ,cause I take whatever I do seriously !! Thanks goldfishpro

Solar powered cooler

I'd like to make a solar powered cooler, however, I am extremely new at this.  I was thinking I could just purchase an electric cooler and a solar panel with the voltage needed, and simply attach the wires.  I feel like that is way too simple to work but I don't know what else to do!  If anyone has any suggestions, I'd greatly appreciate it! The cooler I was thinking of using is here: http://www.amazon.com/Koolatron-W75-Wheeler-Cooler-36-Quart/dp/B00267SQVU/ref=sr_1_11?s=automotive&ie;=UTF8&qid;=1340659801&sr;=1-11&keywords;=thermoelectric+cooler  and the solar panel: http://www.walmart.com/ip/Moultrie-12V-Solar-Panel/16386235 Thanks!

Peltier coolers and condensation?

Hi there, I'm having this crazy idea of building a mini AC based on a Peltier cooler, and connect it to a PC case to introduce cold air inside of it. I have seen a lot of instructables here, but I'm worried about condensation. You know, the "electronics + power + water = Kaboom!" equation. Neither the peltier nor the "cold" heatsink will be inside the case, I'll just blow air thru the "cold" heatsink and inside the case, releasing hot air far away (maybe with a long tube?). My question is if the cold air will carry some kind of "humidity" from the condensed cold heatsink, and if it will be enough to blow things up. I can spare some 60 or 70 watts to make the peltier work, so I'll just grab a ATX power supply for the peltier and the fans. Do you think it will work? Thanks in advance, and Happy New Year. :)

Thermoelectric <Peltier> coolers

I would like to know if anyone out there in Instructables Land knows about Thermoelectric Peltier Devices- what they do and how they work. I have 3 of them in my collection of various electronic components & devices. I consider myself as having a good knowledge of thermoelectric peltier devices. If anyone out there thinks they know more than I do, OR works at a place that manufactures them, please let me know at labrath4@yahoo.com I'm currently unemployed, and would like to work at a place that manufactures peltier components- preferably in the testing and engineering department.

Could this cooler cool?

My idea is that instead of putting ice in the same spot as the beverages, you put them away from them. In the cooler, instead of four walls and one bottom, there would be eight walls and two bottoms. In the inner walls(the walls in the cooler) will carry ice water(with salt to make it colder perhaps?) and so would the very bottom. The center will of course carry the beverages which would become cold by the ice from the bottom and the sides. For a lid, I was thinking of just plain of latches, or a ledge on all four sides to support a lid. Also, which is better for a cooler? Foam or plastic?

solar powered cooler

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.

Heat powered cooler?

It's rather warm around here. And by "rather warm," I mean it's 105 in the shade, and it's 89 in the house with the swamp at full blast. Does anyone have an idea for powering a cooler with pure heat? Perhaps similar to those lightbulb-looking devices that have an inner bit that spins around when placed in direct sunlight, except that is running a little generator that is then running a computer fan, like the ice box air conditioner spotted on this site. The main thing is I'd like the device to actually be powered by heat. Just for the heck of it. Even if it's just heat mechanically powering something to power a fan that I could have just plugged into the wall. So no solar cells making electricity. I can make parabolic reflectors easily if needed, so don't be afraid to use them. What's the best way you can think of to cool off using heat? "Best" can include inefficient but really awesome, like a fresnel lens pointed at a boiler that is providing steam to run a gigantic fan. I'll go get my goggles, ray gun, and keys to the airship.

giant ice box /cooler -suitable fastening materials?

I’m worried bcos the fastening must be such that leakages must be totally eliminated else insulation stands compromised.

Laptop Cooling Pad

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!

What would be a better medium for "cooler cells"?

Talking about making cold packs by reusing plastic bottles. They'd be used in a portable cooler (stacked between spacers for airflow). The obvious option would be just water, but I was thinking something a bit more creative. Possibly: ~water and salt ~water and alcohol ~water and antifreeze ~just antifreeze ~polypropylene glycol ~https://www.instructables.com/id/How-to-make-a-%2420-ice-pack-for-%242/?ALLSTEPS (The bottles would likely need to be epoxied shut to prevent leaking. Their life would also matter, can't have stuff growing in them after a few uses.) Which do you think would stay cooler the longest?

Need help with DIY cooler insulation

Long time fan, first time poster. I'm looking to convert a cool-looking vintage toolbox into a heavy duty lunchbox. I'm currently prepping the metal for paint and looking into what I can use to insulate the box. I've thought of: * spray foam insulation: Good coverage and thermal protection, but not water-resistant enough (think condensation) * fiberglass insulation (pink stuff): Good, but unsure about how cold it will keep things * styrofoam: probably the one inch sheets used for basement walls below grade. Best solution so far. Before I do something that will likely mean stripping the box clean and starting over, I thought it best to see what others might have to say about this.

I recently acquired a thermoelectric mini fridge. As a fridge, it doesn't work so very well - it will get down to ~50 degrees with an ambient temperature of 70. So, I took it apart. You know the saying: "If it ain't broke - fix it until it is." So I now have a peltier effect cool/heater. I put my meat thermometer on the cold side with the fan off - and it gets down to freezing (probably a bit below). On the hot side, with a big sink and fan - it seems to be ~85 at it's warmest point (this sink is about half a square foot and an inch deep). Ideas on where to use? It's 110 service.... It literally almost killed me a few days ago when I touched a transistor sink that was part of the rectifier circuit while holding a plate that was grounded (I got knocked out for a few seconds) I've got a couple ideas, I just figured I'd pool brain power and see what happens :p
