Laptop Cooler that cools the air????

I was looking around at getting a laptop cooler the problem I find is that most laptop coolers just blow air into the intakes. However i was wondering if anyone has seen if there is a laptop cooler out there that will actually cool the air before it blows it into the laptop and if not why has no one made one it cant be that difficult can it or i'm i being an stupid.

Thanks

 

i don't think that's really possible. at least not in a really portable unit. i think one of the closest things to that would be my cryo LX. the cryo LX is made from a full pure block of aluminum so it is always icy cold to the touch. this helps to keep all the air that it pushes out to stay alot cooler than other coolers. it also helps dissipate the heat from the bottom of yur laptop.

 

Buy an air conditioning unit and funnel the airflow towards your laptop?

It can be done, but any kind of cooling mechanism produces heat - uses energy etc.
Its also large, heavy and will contain some coolant that shouldn't leak...

But casting those problems aside - there is a much greater problem - the possibility of condensation inside the laptop if the insides are cooler than the outside air.

 

Mini - air conditioners - evaporative coolers - air conditioning Only $39.95!

perfect.

 

haha - don't post that, someone might actually think it would work well

 

There is no way to do this without spending a huge chunk of money and in the end its just not worth it.

As before mentioned routing an air conditioner could work but you would have to keep an eye on humidity levels.

You could use Thermoelectric cooler or water cool the fans but either cost a significant amount which isnt worth it.

 

what would be a fun project is to make your own cooler. Use sheet metal and tubing and fill up the tubes with freon that goes to a compressor to release the heat in the liquid much like a refrigerator and you could have the tubing sandwiched between two layers of sheet metal that has fans in it. Very simple but you would need to find a compressor that doesn't use a 240v (maybe its 120v i dont remember) source like a fridge. I have never looked up the parts for something like that but it would be cool. totally impractical but cool.

 

Just fyi...

The problem with that is your hand is not that good "thermometer". The heat gets carried throughout the metal relatively fast and what you feel as "cold" is the difference in your temperature and the surface of the metal. In the case of materials that don't conduct heat equally fast (e.g. plastic) it won't feel cold, but it can be at the same temperature as the metal. The best way to determine that is to actually use some sort of a real thermometer or temperature sensor.

 

ok this sounds cool but way over my head i was just hoping that laptop cooling technology would be more advanced by now

 

ummm....what heat is there to carry from my cooler? the cooler itself doesn't produce any heat. there aren't even any 2 surface materials, on the cryo LX, that touch each other to transfer any heat. the top part of the cooler even has a rubber slotted surface, that, on top of the aluminum, to keep any laptop from sitting too close to the cooling surface. there is no metal to metal contact anywhere.

 

isn't air and the laptop cooler both at room temperature??

 

blowing cold air conditioned air into your laptop will make the laptop short out as condensation builds up inside it. the only way it would work is if the humidity level in the room was 0%. if your room was this dry it would be uncomfortable living in it and you would be thirsty alot. Simple science when very cool surfaces (such as metal parts with cold air blowing on them come in contact with humidified air the water condenses onto the surface as the cold temperature slows down the molecules. water droplets inside the system = shortages and dead laptop. Not worth it.

think about it, if this was a good idea it would of been done years ago already. if not in the notebook sector atleast in the overclocking desktop sector. Why do you think cooling solutions jump from regular fans blowing room temperture air to liquid cooling using radiators, because air conditioned air would cause condensation and the desktop would fry

 

Enough said!

Really people, this isn't rocket science; it's as simple as that. And there's no magic alternative to keeping your computer cool.

 

There are two very viable options nobody is mentioning and I'm appalled.
#1 Move to Alaska and build a solar igloo.
#2 Spray liquid nitrogen into the intakes.
Sub zero temps!!!

That sounds like gaming heaven. Imagine!!

 

the laptop cooling deck looks so gimmicky.

 

Yeah i am trying to find the embraco laptop cooler, but it seems they dont make it anymore. My alienware m15x at LANs HDD gets to 60C I have to remove the bottom cover to reduce the temp. thinking of using soft gel packs frozen to reduce temp but its a pain to have to replace them and I will need like 1 for every hour if it lasts that long. I cant believe dell was so stupid when they designed the M15x with no heatsink or cooling for HDD.

the technology is there just no one has developed it or it is too expensive but I recon tons of people with gaming laptops would buy them and then manufacturers may consider there use in docking stations with an overclocking feature when plugged in. http://www.electronics-cooling.com/2008/11/a-cryocooler-in-your-laptop-computer-maybe/

 

Ya think? Any strategically placed table fan, would do as much. Minus the "cool" factor of course.

 

make a simple peltier cooler (thermoelectric cooling), no complex piping or fluid filling required, and is cheap to do. But it does produce condensation.

 

It's a physics thing. The aluminum has a low thermal coefficient, so it transfers heat easily. It is cooler than your body temperature, but it's at room temperature or higher if it's absorbing heat from something like a laptop. It just FEELS cold when you touch it because the heat from your hand is so quickly transferred.

That's also why it's an efficient cooler, up to a point. It absorbs and radiates heat easily. But it will still always be warmer than room temperature if you're using it as a heatsink.

Your original statement was overall correct, unreal25 was simply clarifying that your Cryo LX is not actually icy cold, it just feels that way.

 

Thanks.

To sum up, you can cool different things here (on laptop at least):

1. environment (like put the laptop near AC; I did that on Dell XPS m1330)

2. CPU, directly - by putting the thermal paste and maximizing the contact surface with the passive cooler (usually a piece of metal with a good thermal conductivity; in Dell's case on m1330 XPS it was just some crap sponges that I replaced with copper). Since the speed of heat transport (heat flow) is proportional to the surface, closing all those gaps where CPU isn't touching the metal, can be quite useful.

3. The passive cooler (metal). Once the heat is transported to the metal, it starts to radiate that heat into the air and heat it. So at this step you can put a better cooler, e.g. that spins faster and gets that warm air out faster. You can enhance this somewhat by putting another cooler just beneath it (like laptop cooling stands such as Cryo LX). Keep in mind, however, that you can put as good cooler as you want, but you may not see the difference if the heat transport from the CPU to the passive cooler is your bottleneck.

I don't advise (in case someone thought it seriously ) doing it with liquid nitrogen , apart from the fact that you can get cold burns, it will start evaporating at something like -100 or -200 C.

 

Iv thought of this many times and think its a very reasonable option for the time being until we get laptops that don't generate any heat. Iv left my window open before in the dead of winter in my room to keep my older desktop processor alienware cool. It worked well. Having a device that brings the temperature down doesn't necessarily mean that humidity has to rise. The laptop would be warm enough so that any micro condensation would never be able to cling onto the laptop itself because of how hot it is while gaming. Laptops are built well enough now that things like power irregularities, temperature changes and envirement changes don't effect them, so I cant see micro condensation effecting it.

You could always apply anti condensation stuff to places where you didnt want it to build up also. Maby after extended use over many years ther could portentionaly be weak spots but I still dont see condensation being a factor in being able to make a device like this. Im sure there are engeneers that could make a device like this that puts out less condensation then the coolers that are already on the market.

Just thinking about it though, I always thought of just a regular laptop cooler like we see now, except with aluminum sheet with perferated holes where the ice chilled air could flow threw not just hitting the laptop but creating an area around the laptop that cools the laptop, then the laptop burns this cool air so the device dosnt act like a air conditioner. This or just thinking about it now you could have like a mini fan air cooler like you see with the football players and just point it at the laptop without the mist.

 

Intel was working with Coolit to develop one, but it never made it to market as far as I know.
