Keep cool in Bed

Keep cool in Bed

Almost everyone has experienced the sleepless nights resulting from summer heat waves. Air conditioning may be an answer, personally I dislike a very cold room I just want a cool bed.

Well this is my solution.

Step 1Cooling Breeze

Cooling Breeze
Many years ago it struck me that what I needed in bed was a cooling breeze that would save me having to lie on top of the bed with the windows wide open.

With that in mind I assembled a simple plywood trunking with a space at the bottom for a small PC fan. The top of the trunking I tucked under the sheets at my feet. Running from a wall wart power supply (12 volts) and a switch by the bed side I was able to turn the cooling breeze on and off as I required.


Unfortunately the old one got dismantled for other projects in the winter - as yet this year hasn't been hot enough to get me making another. BUT

It is very simple a 6 mm thick plywood box shaped like a letter S in a suitable size for the fan you will use  so that the lower part sits on the ground and the upper part sticks over the edge of the bed under the sheets. You will have to select the sizes to suite the height of your bed.

In the lower section a hole has a PC fan, or similar, is mounted in it.

I used an old 12 volt cooling fan because I had it but any fan that can move air will do.

Mounting will depend on what your fan looks like so again you have to design to suite your parts.

My fan was powered by an old wall wart type power supply with a bedside switch to turn on and off as required.

This design idea is so flexible you may be able to find suitable trunking in the kitchen department of your local DIY store.

Hi Rick, To keep the fan, blades, and ducting CLEANER, I suggest a large surface area, and non-restrictive type of air filter at the intake and before the fan.

A bit of PVC pipe would work well for this too. Mount a fan on the end of a 90 degree elbow. then up and another 90 degree elbow. I might make two and join them to make a ssquare, so that they will stand. I can have one on my side of the bed and my wife can have one on her side. Good Idea
