Wärmedurchleitung

Wärmedurchleitung, also known as thermal conductivity, is a measure of a material's ability to conduct heat. It is defined as the quantity of heat that flows through a unit thickness of a material in a direction normal to a surface of unit area, due to a unit temperature gradient under steady-state conditions. The thermal conductivity of a material is an important property in many fields, including engineering, physics, and materials science.

The thermal conductivity of a material is typically expressed in watts per meter-kelvin (W/m·K). It is influenced by several factors, including the material's structure, composition, and temperature. For example, metals generally have high thermal conductivity due to their free electrons, while non-metals typically have lower thermal conductivity.

Wärmedurchleitung is a crucial factor in the design and analysis of heat transfer systems, such as heat exchangers, insulators, and thermal management systems. It is also important in the study of heat flow in buildings, electronics, and other applications where heat transfer plays a significant role.

In summary, Wärmedurchleitung, or thermal conductivity, is a fundamental property of materials that describes their ability to conduct heat. It is a key factor in the design and analysis of heat transfer systems and has wide-ranging applications in various fields.
