UCLA scientists have now created an air conditioner that can easily fit into your pocket. The flexibility of the cooling device offers a diversity of use in electronics and other things.
BEATING THE HEAT
As the temperature soars up, the need for cooling devices has increased. People are facing the brunt of harsh sunlight along with having an overheated smartphone battery. Amidst this problem, simply imagine having an air conditioner that you can carry with yourself easily because it fits into your pocket. Imagine not having to worry about your smartphone heating up. Shocked and excited? Well, UCLA researchers have now made that dream a reality. They have developed a pocket-sized cooler that can beat the heat.
UCLA has always been inclined in conserving the energy and reducing the expenses. UCLA focuses the majority of its work in conserving the environmental resources. The tiny device is yet again energy efficient and works in an environment-friendly manner.
The present air conditioners release a lot of carbon dioxide into the atmosphere and are loud. The thermoelectric coolers don’t cool that much and are costly. But breaking from all this, the new device harnesses an electric field for diverting unwanted heat. The device is good for the environment and is less costly.
The experiment showed results on the Samsung Galaxy S4 by cooling it down by 14.4 degrees Fahrenheit in mere five seconds. The device is said to be taken for future use into the wearable electronics for comfort cooling. It can easily and noiseless-ly cool down the electronics. The researchers are looking for funds which can develop such kind of technology for the consumer use.
FEATURES OF THE AIR CONDITIONER
The small air conditioner uses solid-state refrigeration that offers the high intrinsic efficiency of thermodynamics by implementing the use of a flexible film made up of electrocaloric polymer along with having the mechanism of electrostatic actuation. The role of reversible electrostatic forces is to help in the reduction of the power consumption and ease the transfer of heat through the thermal contact by using a heat sink.
2.8 watts per gram is the cooling power of the device which offers a COP of 13. This compact yet highly effective technology has created a pathway for a lot of practical applications. The device even cools down the overheated battery of the smartphone and can be used further for developing other compact electronics.
