Thermal Resistance

Thermal resistance is a heat property and a measurement of a temperature difference by which an object or material resists a heat flow (heat per time unit or thermal resistance). Thermal resistance is the reciprocal of thermal conductance.

  • Thermal resistance R has the units (m2K)/W.
  • Specific thermal resistance or specific thermal resistivity Rλ in (K·m)/W is a material constant.
  • Absolute thermal resistance Rth in K/W is a specific property of a component. It is e.g., a characteristic of a heat sink.

Famous quotes containing the word resistance:

    “He made no resistance whatever, and was stabbed in the back.... I must not dwell upon the fearful repast.... Words have no power to impress the mind with the exquisite horror of their reality.”
    —Edgar Allan Poe (1809–1849)
