Question:
An inovative Idea for notebook cooling
I am pretty sure everyone here knows that heat for notebooks are terrible and its usualy a battle that we cant win. Even with the "notebook coolers" out in the market they seem to have little to no effect on the heat created by the notebook.
I believe we should instead of using passive fans to cool a notebook we should use Peltier Junction Thermoelectric effect and just take the heat from one side of the notebook to the other side of the notebook cooler pad. I believe this would reduce noise and reduce temperatures to a passive level and power consumption would not be a problem.
I dont believe condensation will be an issue also because the heat transfered from one side of the board to the other side of the notebook cooler will cause enough of a difference for condensation.
well thats just my thought if anyone has comments or ideas leave a note
BTW. Peltier Junction is basicaly heat transfer from one area to another area

Why do you believe we should use peltier instead of passive cooling? Do you have evidence that traditional notebook coolers are inadequate? Please describe what you mean by the term "passive fans"??
How would this reduce noise? You'll have even more heat to move, but instead of being on the notebook, it'll be on the hot side of the peltier. How do you propose to move that heat if not with noisy fans?
Why do you believe power consumption will not be a problem? How much power does your proposed solution consume? Peltiers consume a LOT of power.
How will you avoid the problem of condensation and/or frost?
I think maybe you have some more homework to do. A lot more.

Re: An inovative Idea for notebook cooling
I was under the impression that current cooling methods just took advantage of radiation and conduction phenomena of heat. Heatsinks conducting heat with a fan to blow air against it, creating a gradient from hot to cold. The main problem with heat in computers is the interface between the heatsink and components themselves at the molecular level, which is addressed by thermal paste.
In order to moving heat from cold to hot requires a huge amount of energy and won't happen by itself. (2nd Law of Thermodynamics) The additional work by itself would be contributing to the heat issue. Moreover, an efficiency of 5-10% of a Carnot refrigerator doesn't sound very good.
Don't take it personally. I still admire your creativity.

Another question: How do you propose the mount the peltier device to the notebook? :confused: A peltier requires a solid physical interface with no air-gap, implying a permanent or semi-permanent attachment, along with all the equipment to cool the peltier's hot side....

I say try it! If it does not work, oh well
Answer:
Re: An inovative Idea for notebook cooling
first off, fan cooling is considered "active cooling". passive is without fans. like a large heat sink where the heat can just dissipate.
your idea is good, but it requires energy and is only 10% efficient. that might be an obstacle for you.
but seriously, make one and report back.

Re: An inovative Idea for notebook cooling
thanks, for the redefinition sorry if that caused anyone to flame me >.<, this idea wouldnt be like a portable notebook cooler because it would have to run on a stand alone powersupply, also because it would need to dissipate the heat i would have to design this notebook cooler to be angular and have heat sinks at the bottom. As for frost and condensation i would need to have silica beads at the top or the bottom. As for a solid physical lock between the device and the notebook i might have to either have some kind of locking hinge to bind then notebook and the cooler together..
I think this idea is worth looking into thanks for the support and any other ideas would be awesome
Yes i do recognize this would actualy more heat, but the heat wouldnt be directed at the notebook, the heat generated by the notebook and the notebook cooler would be transfered to the back end of the notebook cooler. While the back would get mildy warm the notebook would stay cool in theory..
Sorry if this sounds farched i had a dream about it at 2 am and i decided to write this down lol so please understand i havent gotten this down solid yet

Re: An inovative Idea for notebook cooling
The use of thermoelectric cooling requires more heat to be eliminated from the system. Aside from that, it also requires far more power than conventional cooling systems...we're talking about a order of magnitude here. Why anyone would put a thermoelectric device that generates enormous heat and uses up huge amounts of power into a portable machine that's already heat and power constrained is beyond me.

Re: An inovative Idea for notebook cooling
it would be for desktop use. so like a docking station type thing could incorporate it. its not for portability. it would be plugged in.
i say, crunch some numbers and if the numbers are viable, make a design, and if thats viable, make one. then report back.

How is that even going to work though? Do you have to open up the CPU bay to install the thermoelectric cooler every time you dock? Because you certainly can't take the TEC on the road with you.
