Thermal resistance意思

"Thermal resistance" is a term used in physics and engineering, particularly in the context of heat transfer, to describe the property of a material or an object that resists or slows down the flow of thermal energy from one side to the other. It is the opposite of thermal conductivity, which is the ability of a material to conduct heat.

The thermal resistance of a material is typically measured in units of Kelvin per Watt (K/W). A higher thermal resistance means that the material is better at resisting the flow of heat, while a lower thermal resistance indicates that the material conducts heat more easily.

Thermal resistance is important in a variety of applications, including the design of electronic devices, where it is used to prevent overheating, and in the construction industry, where it is used to insulate buildings and keep them at a comfortable temperature.
