The Different Between Thermal Conductivity and Thermal Resistance

Relationship Between Thermal Conductivity and Thermal Resistance

Thermal conductivity and thermal resistance are two closely related physical properties, and the following relationship exists between them.

1.Thermal conductivity and thermal resistance are multiplicative inverse related: thermal resistance is equal to the thickness of the substance divided by thermal conductivity.

2.Thermal resistance can be expressed as the reciprocal of thermal conductivity multiplied by the thickness of the substance.

3.The higher the thermal resistance, the lower the thermal conductivity, and the worse the ability of the substance to conduct heat.

Thermal conductivity and thermal resistance are two important concepts related to thermal conduction, which are important indicators of the conductive properties of substances and have wide applications in the fields of thermal engineering and materials science. Understanding the relationship between them can help us understand the mechanism of heat transfer, optimize the design of heat dissipation solutions, and make reasonable judgments and decisions in material selection and heat sink applications.
