Introduction: Cheap and Easy Fan Cooling Jacket
Have you ever wonder if you can run back into an air-conditioned room while you are grilling BBQ? This Fan Cooling Jacket can help you! It is equipped with two battery-powered fans, which generates an air flow from the bottom to the collar and to the sleeves. It reduces your temperature by evaporating your sweat. The air flow from the collar also cools your neck, head, and face.
The objective of this instructable is to create a functional fan cooling jacket with minimum investment.
Step 1: Materials
- One or two size bigger than your normal size (I used XL)
- Synthetic fabric that are not wind permeable (I used nylon)
- Have waist rubber cord to tighten the waist to minimize the air escaping (see second pic).
- Have a wide opening collar so that you can direct flow to your face and head.
- You can get any generic fan kit.
- Do not buy any that are operated with 12V.
- Make sure it can glue plastic and synthetic fabric together.
- Any USB cable can be used but I used one specific for charging.
- Soldering Irons
- Soldering stand with clips
- Anything that can be cut with scissors.
Step 2: Power Cable Soldering
The kit has a power code with three 3.8/1.4 mm plugs. This has to be replaced with a USB plug.
- Identify the one that is meant for power source. Clip it and expose the wires.
- Clip the USB cable and expose the wires.
- Connect them temporarily and make sure the polarity is correct by spinning the fan.
- Solder them together and cover it with heat shrink tube.
- Make a knot so that they withstand pulling force.
Step 3: Support Rings
To avoid tearing of the fabric around the fans, it has to be reinforced with plastic rings.
- Cut out two plastic rings out of a clear folder by tracing inner circle of the fan-cover ring with a permanent marker.
- Make sure it snugly fit the fan. Don't make it too loose.
- Width can be 2-3cm.
Step 4: Attaching the Support Rings
Using the adhesive, attach the two support rings on the inner surface of the jacket at the lower bottom.
Step 5: Making Holes
- After the adhesives are somewhat cured, cut out a circle with a pair of scissors leaving 2-3cm margins.
- Make radiating incisions from the hole reaching the plastic rings.
- Apply adhesives and attach them to the inner side of the plastic surface.
- The petals should be on the inner side.
Step 6: Unstitching Seams
To cool your arms, you should have good air flow through cuffs. Unstitch the seams of cuffs and get rid of rubber bands that tightens the cuffs.
Step 7: Place the Fans in and Ready to Be Cooled
Place the fans in and attach the USB cable to a portable battery pack and enjoy the cool breeze.
