Coolers are a must-have in the season of summer. But what if I told you that you could make a personal cooler being in the comfort of your own house, using any average household item that could be found lying in the corner of your home! Let’s start with this article on how to make a cooler using thermocol.
The science behind a cooler is not that complex and can be contracted with ease, but patience is substantial as well. As the process does include some technicalities, make sure to follow all the steps mentioned below accurately to make sure you make your thermocol cooler within a couple of minutes.
- Glue gun
- Thermocol (2*1cm x 7cm)(2*12cm x 12cm)
- Ice cream sticks (13 pieces)
- DC motor
- Attachable fan
- battery & battery connector,
Step 1: Make a hollow shape using thermocol shapes. Attach the three rectangle thermocol pieces at right angles to each other using the glue gun. Then attach the hollow rectangle that would mark the front of the cooler. Fix the square thermocol piece as the base.

Step 2: Form a ‘square’ shape by attaching the ice cream sticks and then stack 5 additional sticks on the square plane at a perpendicular angle. Stick this construct into the opening of the thermocol body. The ice cream sticks would form the air deflectors of the cooler.

Step 3: Attach two ice cream sticks to the DC motor to form its support. Stick these sticks to the top of the thermocol model. Make sure the rotator faces downwards.

Step 4: Make a circuit for the DC motor using the battery, battery connector and spare wires. Attach a switch to the circuit to switch on/off the cooler as per your wish. You can watch tutorials for the same on youtube. Attach a fan on the rotator facing towards the base of the thermocol model.

In my opinion, making a working and energy-efficient cooler in your own home using basic resources and electrical equipment is quite a smart and cost-efficient thing. Like every year, we face a higher degree of global warnings, and the price of coolers skyrockets for all the months they are needed the most.
