Definition: The word ‘Koppen’ is a German term which literally means 'baffle' in English. It originates from a word that has been used to describe an electric fan, but can also refer to something that is designed to generate heat, or a system that provides circulation. A baffle is a device used in mechanical or electrical systems to prevent the flow of hot air and cool air (or cold) to different parts of a complex structure. These baffles are typically made of metal, plastic, or other materials and are used in the following ways: 1.

Passive Cooling

: Baffles work by generating heat through their material properties. This is useful for cooling very dense or hot items, such as a car engine or a large appliance. 2.

Ventilation

: In electrical applications, baffles can be used to create an airflow that helps cool devices and other objects located near them. This is especially important in environments with high heat loads where heat transfer rates are low. 3.

Energy Storage Systems

: Many systems, such as wind turbines or solar panels, use baffle elements to generate energy from the air flow. 4.

Heat Exchangers

: In HVAC (heating, ventilation, and air conditioning) systems, baffles can help separate hot and cold gases within a heat exchanger, reducing temperature differences. 5.

Heat Transfer

: Baffles are often used in commercial applications like the food industry to help distribute heat evenly through machinery or other equipment. The definition of 'Koppen' in German is quite broad. It could refer to different things depending on context and the specific application. In this case, it seems that you're referring to a concept related to ventilation systems, specifically the role of baffles in maintaining air circulation and temperature balance within a building.
