Electronic device, surface temperature calculation method, and surface temperature calculation program

摘要

An electronic apparatus includes a housing; a substrate disposed on the inner side of the housing; a plurality of temperature sensors disposed on the substrate; and a processor. The processor performs a procedure including calculating heat source temperatures of a plurality of heat sources disposed on the substrate from temperatures measured by the temperature sensors by using a first heat transfer model not including a first parameter representing a transient response of heat transfer from the heat sources to the temperature sensors; and calculating a surface temperature of a surface of the housing from the heat source temperatures by using a second heat transfer model including the first parameter and a second parameter representing a transient response of heat transfer from the heat sources to the surface.
