How to Stay Cool in the Heat

it allready exists it is called a fan with a iceblock

but jokes aside it would not suprise me if they allready have something like this in Japan.

One solution would be to go to a car graveyard and get a aircon out of a car and use that one.(with some modification)

Hello,

My nephew had a Halloween costume this year that was a "Sumo Wrestler". It was made of a light material which was filled by a small fan that ballooned the costume up to look like a Sumo.

It was very cheap, simple and quiet and safe to use.

So try the local party shop or buy a personal fan and adapt it.

There are medical devices that recirculate warm, cool water around an athletes (typical use) injured body. They can be found on line and are made here in California, Berkely I think.

I do not mean to put you off but, try google the already developed items and try then to improve on them or see why you had never heard of them.

Ask yourself is it worth your precious time to develop this item as there must be a ready market for your idea or will you end up paying to create one.

Good luck, do your due diligence and you may enjoy the outcome.

I saw a device a while back for athletes and people who for medical reasons cant control there body temp it was a shirt with some thin tubing sown in and a small pack that you put ice bricks in it had a small pump that circulated the cool water around the shirts tubing to cool the wearer not sure where you get them from though

US$210 is a tough price point. And the other restrictions make it difficult too.

As another commenter mentioned, probably your best bet is just to ventilate the suit with one or more small fans / blowers. Maybe use a blower and duct the air via perforated hoses throughout the suit. Paying attention to get near hotspots of back, chest, underarms, etc. Be sure the victim occupant wears sports clothing that wicks away sweat. Exhaust near the head.

But having had some experience with small blowers, they're usually far from quiet. Maybe the suit will muffle it though.

If you really must go "high tech" then I guess the way to go would be to make a hommade water-circulating cool suit. Something like the thing seen here:

(as always, no endorsement of the above product or vendor is written or implied)

I suppose some tubing sewn to a shirt, a box full of ice water, and a very small 12V pump + battery could be put together for cheap. Not sure if you can fit the ice box inside the costume though.

Or if you're really penny-pinching replace the pump and battery with a squeeze bulb inside the costume. Either near the hand so the occupant can squeeze occasionally or under one foot so that each step taken squishes the bulb.

Less than a dollar,buy a ice pop and stick it in your undies.

You, sir or madam, have obviously never had first-hand experience with the sweltering tropical nightmare that is my undies.

Ice pop indeed.

Vortex Tube should be the solution. This is just a mechanical gadget, with no moving part. You have to connect compressed air, and you get a cool stream, which you may distribute in your cool suit.

You may google "Vortex tube" to find other manufacturers.

Get more information about the noise. It make good unbearable noise. But, if it is properly enclosed, may be it will be sufficiently silent.

All the best

There are 'cool vests' for Hot Work in various industrial applications. Stick'em in the freezer for a while. Put something on over them to retain the coolth. Good for a couple hours anyway, depending on ambient temp. Usually in the 110 to 140 deg. F range.

I remember a guy telling me sometime back the use of Peltiers for cool vests. Since more heat is to be removed for getting more cool from the Peltiers, I wonder where they will fix the heat dissipating fan. What you have is a guy HOT from outside but really cool inside

This not be what you are looking for but may give you some ideas to develop a lower lever product. http://www.gameready.com/index.htm This is a rehab unit that is more than cooling. A friend is the manager for the equine market

In the summer we keep wet strips of cloth about 2 ft long and 1 ft wide in the freezer. Just wrap one around your neck and that cold cloth lowers the temp of the bllod going to your head and then the resy of your body.

Easy does it!

Pressing the frozen cloth to the veins in your neck will cause more real bad headache I guess it cools the blood too fast.

We are debetting between us, and that "if it don't work", is missing and has gone to fix something else.

We do not know, if he is satisfied about the information he received (and hopefully read)
