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 ?


oh my genuisses at work i never have cool ideas so i realy love to read what everyone else is so thoughtful of people in florida would love a cooling hat as long it didnt weight 20 lbs

Maybe I will have to patent this...5,789 prototypes later....And a business proposition....

i dare you to wear that into a airport....watch you get shot...

Correction - they would probably let you out.

Anyways I am definitely not going to walk int the airport with a computer cooling system or a heat sink on my head

Tear a heat sink out of an old laptop. Attach a small fan to it. The heat sinks in laptops are thin. Thinner than shown at least.

hmm I have seen a laptop heat sink made of aluminum and I do have some smaller ones. (I just googled for the heat sink picture)

although smaller, those heat sinks are copper, so the weight is about the same.

. Great idea, but I think you'll need more power than 1-2 9V batteries (assuming you mean "transistor" batteries). And you'll probably need more than one heatsink/fan (more battery). If you have a battery with enough capacity, use Peltier coolers. . I'd try mounting the pump, reservoir, fans, heatsinks, &c in a mesh vest - too heavy to put all that weight on your head/neck.

you could put the heavy components in a backpack and have a hose wrapped in a cone shape and set it on your head.
