bilkjøler

A bilkjøler, or car cooler, is a portable appliance designed to keep food and beverages cool within a vehicle. These devices typically operate by thermoelectric cooling, also known as the Peltier effect, which uses an electric current to transfer heat from one side of a semiconductor device to the other. They are powered by the vehicle's 12-volt cigarette lighter socket.

Car coolers come in various sizes, from small personal units that can hold a few drinks to larger models capable of storing groceries for a family trip. They are often used for road trips, camping, picnics, or any situation where access to refrigeration is limited. The internal temperature of a car cooler is generally influenced by the ambient temperature outside the unit. While they can cool contents to a certain degree below the surrounding temperature, they are not as efficient as traditional compressor-based refrigerators and are not designed to freeze items.

Maintenance for most car coolers is minimal, usually involving cleaning the interior and ensuring the ventilation grilles are free of obstruction to maintain proper airflow. Their portability and ease of use make them a convenient option for travelers who wish to keep perishable items fresh and drinks chilled on the go.
