Engineering a Solution to Laptop Heat

Hi all,

You all may or may not have seen my previous post, but here’s the basic gist of it. I am a high school senior from Niskayuna, NY. I am currently at the beginning of a year-long project for my Engineering Design and Development class. At this stage in the process, I have chosen what I believe to be a problem, and have created a very brief survey which I need to distribute to my target market (laptop computer users) to verify that this is indeed a problem. After analyzing these initial results, I have done more research and created a revised survey. I would really appreciate if you guys would take this quick 5 question survey.

Thank you,

if i remember right! this one is like the other survey i cant recall who is it, but it is for cooling laptops correct me if i wrong
 
The cooling issue is simple, needs to be on a higher end cooling pad that forces air into the bottom slot of the laptops if your laptop is like mine where the fans blow out the hot air on the sides.

A majority of laptops I see only have fans pushing air which makes no sense to me because they also need fans pulling air in as well. Push out the hot and replanish with cooler air.

Whether the air is pulled or pushed is irrelevant, a single, efficient fan pushing or pulling could possibly do a better job than multiple, less efficient fans.

Laptop cooling isn't simple. There are a number of factors that need to be considered. For instance, a powerful fan that moves substantial air and keeps the temp down may be too large to fit the case, use too much battery, be too loud, be significantly costlier, etc...

Actually fan location and air movement is key, When I was in the Navy I worked on a engine that heated up tp 2,000 degrees in a container smaller then then most of your living rooms and what kept the gas turbine engine cool was fan placemet and direction of air, but what do I know as a mechanical engineer :rolleyes:

Nobody said fan location wasn't key, the issue is moving a volume of air and it doesn't matter if it's pushed or pulled as long as it's sufficient to carry off the radiated heat.
 
trying to explain cooling to non Mechanical Techs is hard but the principle is the same, a large amount of heat be produced in a very tiny space but where as a laptop can change in temp slightly with no damage this is not the case with Mechanics, must maintain the same or serious damage may happen. My theory has been tested and it works being that it is currently used on billion dollar warships. Not to mention people who design these things are far better paid then the man who designs the laptop because of a better knowledge level.

Hmmm... I woulda thought that a hotshot mechanical engineer would know that something that has been tested and proven to work in billion dollar warships would no longer be referred to as a theory.

I am so proud that you found a error in my post :), fine not theory I will call it a law if it helps you understand I am right.

The issue with one high powered fan is unless it is directly center of the system it will not adequately cool as two fans producing half the power on opposite side pushing and the other pulling new air would be more effecient.
 
All I am trying to do is to get you to realize "one size does not fit all". It really depends on many factors and it is not necessarily a fact that a 2 fan design would cool better than a single fan design. Not only that but compromises may have to be made in order to satisfy other requirements such as noise reduction, weight, cost, etc...
 
I say have some sort of liquid cooling going throughout the laptop. Internal made out of something strong. Copper is not nessesary strong, but would work.

I would see this being offered in high performance laptops. A person buying a high performance laptop, most likely won't drop it, leave it in wide range of temps, not neglect it in anyway. Wish something like this was invented.
 
One easy way for coolling down temps of a laptop is a coolling fan pad

For advance only users, that know to disassemble complete the laptop you may need :

Thermal paste,soldering iron solder,fan pad for laptop.

Fisrt disassemble the laptop, clear all dust, especially in coolling system fan.

Remove the old thermal paste completely from CPU and any else chip can be apllied thermal paste.
Put new thermal paste in clear surfaces of CPU and any else needed. (Eg: sometimes GPU have a cooling metal, there can applied new thermal paste)

Thermal paste if completely dry, has no big use, you must remove and clear it, and put a fresh dose...

Then you must use the soldering iron solder and carefully remove the plastic of bottom of laptop base case.

That will release the motherboard directly. Will allow more temp to drop away.

Then just put a coolling pad carefully down, avoid to touch the motherboard in any case, for more cool system.

To remove some no vital plastic from the bottom is no big deal.
But you must carefully nothing no touch the naked motherboard parts.

Please note, laptops with no naked motherboards.
Has no designed to oparate in hot days, such summer days and especially in direct Sun light. And never direct in to phisical humans laps. And always must be placed a laptop, in to a flat area.
Never in a bed or in a non flat place.
In final lines, just no cover the airs holes of laptop...

Here is mine naked laptop (user custom laptop)

I don't think I would go as far as removing parts of the laptop case leaving the innards exposed, the potential for physical damage to the motherboard and other components is too high for me. The only way I might consider something like this would be if I permanently installed the laptop cooling pad to act as a replacement for the bottom of the laptop case.
 
Look facilities no plan to create immortal laptops.

The short case of laptop motherboard, reduse life of mobo very much.

The most reason of a dead laptop is the broken screen or a burned laptop motherboard.

And by the way, the normal life of a laptop is 5 years.

After 5 years, only linux can play...
