In the world we live in today it seems like there is a mobile version of everything. Almost everything is getting smaller and more efficient. A cool box is no exception to this. But how do car coolers work? You may ask. Well, that is what this exciting new post is about. So pull a cushion, sit back, and relax, as we take you into the world of car cooler boxes and how they work.
Car cooler boxes work by a phenomenon called a Peltier effect. It uses the Peltier effect as its method for cooling. This effect is usually seen on the lid of the cool box. It is designed this way so it stays away from the foods and drinks that it houses. So the cooler box also has a fan system that transfers heat from the inside of the box to the outside surroundings to make sure that its content remain cold.
Also, car cool boxes are powered by the 12V cigarette lighter port of your vehicle. If you are at an outdoor location, you can get an external power source. But make sure to remember to step it down to 12V maximum to avoid damaging electrical components with a power surge. If you are powering it up with your car, make sure that the engine is already running. If not, it might end up draining your car battery.
The importance of a car cooler box
Campers and people who love to go on picnics and get-togethers will tell you this an essential part of their luggage. Its main importance is to keep food and drinks cold, fresh and ready for a given time – even without loading it with ice! It gives a very good option to store food whilst making it cool at the same time. So whether is for outdoor use or for indoor use (it can be used in the house as a mini refrigerator), the electric car cooler is an essential device to have.
However, if you notice that you have to stay extended number of hours outside, and there is no means to a power source whatsoever, you can fill up the car cooler box with ice and then cover it. The insulation will still keep everything in the box intact.
How long do car cooler boxes retain temperature?
Upon full charge, a normal cool box can retain temperature for about two days. In fact, the bigger ones that serve other purposes can even retain for periods longer than that. But once you notice that the temperature in the box is beginning to rise, you might want to connect it back to a power source.
Car coolers can keep food and drinks at temperatures up to four degree Celsius. An advantage it has over the normal refrigerator in the home is a term known as differential cooling. This is the ability for the box to stay cooler as the temperature outside gets hotter. That’s why this gadget is very important during the summer break.
Another important feature to note about the temperature of a car cooler box is that some recent types have the ability to freezer its content. So the same box that can keep your vegetables cool can also keep your ice cream frozen. This is a two-in-one package that saves you from getting another box entirely.
You should also know that for a car cooler box, you might not have the option to regulate the temperature. So it is recommended to keep food that you don’t want frozen at the top of the pack. This is because the temperature is cold from the base of the cooler box.
