Cooling cabinets do not need electricity, do not need ice, can be folded neatly and still keep cold effectively

This "refrigerator" applies a secret from the human body, and the idea comes from the very hot climate in Vietnam.

When going on a picnic, the problem of keeping food cold always makes us headache. You can ice but the carry will be heavy and troublesome, not keep for long. And no one is so diligent that he carries the refrigerator with all kinds of gas cylinders, right?

The good news is that with the advancement of technology, in the near future, we will have more cool refrigerators. For example, the Yuma 60L refrigerator (Fenik brand) does not need to use electricity, does not need a fan and is very compact. The product is currently in the final finishing steps and soon launched.

Saying that the fridge sounded great, but Yuma 60L weighs only 2.3kg, can be folded up for ease of movement and then opened within 30 seconds.

Yuma refrigerator 60L.

. can "shrink, enlarge" as easily as Doraemon's.

This mini fridge cannot be chilled with "extreme" cool beer. However, it is capable of keeping fresh fruit within 5 days without user intervention.

Yuma 60L's cold-keeping mechanism is completely thanks to water, and is inspired by the body's sweat-draining mechanism. But the key secret lies in the fabrication technology of special fabrics called PhaseTek , which has been patented.

The outer shell of the Yuma refrigerator is made of PhaseTek fabric, which functions like . human skin. And the food inside is contained in a plastic layer that is safe for health. Between these two layers there is a "magic" gap - you will pour water into it to help Yuma refrigerator work.

Pour a little clean water and wait and see what the magic is.

When the food inside produces heat, it passes through the plastic and meets the water. The water meets the evaporating heat, then passes through the special material layer to escape to the environment, bringing with it the heat. It sounds like we sweat to cool our bodies, right? According to the inventors, if the outdoor temperature is 32 degrees Celsius, the inside of Yuma's refrigerator is only 18 degrees Celsius.

Two co-founders of Fenik brand (including Yuma refrigerator products) are Jeremy Fryer-Biggs and Quang Truong. Talking to Digital Trends, Quang Truong said the idea of ​​creating Yuma refrigerator appeared when he worked with farmers in Liberia and Vietnam. When they bring fruits and vegetables they have harvested to the market, it is difficult to keep them fresh for a long time.

According to the figures of Yuma inventors, there are now 1.2 billion people in the world who do not have a refrigerator, because the electricity source is not guaranteed or it can also be caused by natural disasters when the electricity is cut abruptly.

Yuma 60L refrigerator price is estimated at US $ 120 (~ 2.8 million) for personal use, or US $ 250 (~ 5.8 million) for family use. It will officially sell and deliver from March 2019. You can see more information on the Kickstarter page that Yuma refrigerator inventors are calling for community funds.
