An Instant Cooling Hand Refrigerator

Instant cooling hand refrigerator is a very small refrigerator intended for home and field use that can cool beverages and food products under a minute for preservation or satisfaction. This means there is demand of fast cooling beverages at home specially for beverages and there is no simple in size refrigerator on the market. This design solves both problem, it´s size is no larger than a big mug and cools faster than high duty refrigerators. This is done by using conduction heat exchange between cold coils which is found after expansion valve and the food product or the beverage. All refrigerators have compressor, hot coils, expansion valve and hot coils. In current refrigerators the cold coils cools the air inside the refrigerator and the cold air cools the products. But in this case the air is removed and heat exchange is directly between the cold coli and the product. The device mainly focus on law of thermodynamics.

Innovation Description

At home I have experienced my beverage is too hot to drink for me and guests so i put it in freezer and waited for 30 minutes to drink because i was out of ice. And i am sure i am not the only person who have this problem so if this device is on sale i am sure it will be sold quickly. Also cooling beverages and food products on a field with out ice is highly unlikely considering the size of current refrigerators. This device solves this problem because it is light and can be hold by hand. Currently it is only in design stage because of luck of finance but if I get funding I will build prototype and sell it all over the world. The cost of the refrigerator is very less than the courrent least mini refrigerators because it has small body coverage.

Competitive Advantage

The market is all over the world, considering it´s large scale I will start with my country then export to neighboring countries and the world. The current market competitors would be a no one because no company has the same product as mine. Therefore my advantages is I will monopolize the market.
