This page provides all possible meanings and translations of the word thermal conductivity

U.S. National Library of Medicine

  1. Thermal Conductivity

    The heat flow across a surface per unit area per unit time, divided by the negative of the rate of change of temperature with distance in a direction perpendicular to the surface. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)


  1. 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. Thermal resistance is the reciprocal of thermal conductance. thermal resistance R in K/W is a property of a particular component. For example, a characteristic of a heat sink. Specific thermal resistance or specific thermal resistivity Rλ in /W is a material constant. Thermal insulance has the units /W in SI units or /Btu in imperial units. It is the thermal resistance of unit area of a material. In terms of insulation, it is measured by the R-value.
