Beat the heat with this awesome DIY mini portable evaporative room cooler!
At the very first sight, this thing looks like a little model of traditional Indian swamp coolers which are/used to be very common in most of the households. Of course these have been replaced by air conditioners in the recent years. However, this idea continues to be one of the most creative.
The principle behind the working is as simple as, 'evaporation causes cooling'. When air passes through a damp pad usually made of 'Khus', it results in a cooling effect. The pads are mounted on a steel/iron box and are exposed. A pump is added to wet these pads and an exhaust is used to suck air through these pads and then blow the cooled air.
"Khus is a native Indian grass which has traditionally been used as a coolant in Indian households. Largely used as evaporative mats and screens, the dry air cools as it passes through layers of wet khus. Cultivated in Madhya Pradesh and Rajasthan, the grass is transported largely across North India during summers. With the air conditioners contributing incessantly to the pollution, one might want to give the traditional khus mats a relook."

Now coming to the point, I decided to build a smaller/portable/battery operated version of the same after I saw some vanaspati (ghee) metal containers being thrown away, which could actually be brought to some great use. Not that I would use this thing daily, but this can be helpful for rural areas and hostels/dorms where air conditioners aren't allowed.
The biggest advantage if such coolers is that they do not cause any kind of pollution and this one being operated using a 12V battery, does not consume much power. However, this cooler would not work in humid/damp conditions because in such cases, air already holds a lot of moisture due to which rate of evaporation is low hence low cooling.
The basic parts used here include a 12V motor with blades, a 12V water pump and a PWM powered by LM555 IC circuit to control the speed of the motor. Power supply can either be a 12V battery or an adapter.
Total cost of the parts used in this project: $10 approx. (650 INR)

[@suabroboro]

can we place the fan behind the cooling pad with both cooling pad and fan facing towards us but the fan behind the pad with water flowing over the pad?

[@SaiyamAgrawal]

Yes you can. But that would not be too effective + the air flow would be too low as it will be restricted by the cooling pads in the front.
