Method for estimating temperature at a critical point

摘要

Methods and apparatuses are disclosed to estimate temperature at one or more critical points in a data processing system comprising modeling a steady state temperature portion of a thermal model at the one or more critical points using regression analysis; modeling the transient temperature portion of the thermal model at the one or more critical points using a filtering algorithm; and generating a thermal model at the one or more critical points by combining the steady state temperature portion of the thermal model with the transient temperature portion of the thermal model. The thermal model may then be used to estimate an instantaneous temperature at the one or more critical points or to predict a future temperature at the one or more critical points.

1. A machine-implemented method comprising:
retrieving, by a processor of a data processing system having a housing that houses at least the processor and a memory, from the memory of the data processing system, a representation of a thermal model of a temperature of a target location on the housing of the data processing system, wherein the thermal model includes:
a first component which estimates a steady state temperature of the target location on the housing of the data processing system based on a steady state temperature behavior of a location inside of the housing, anda second component which estimates a transient temperature of the target location on the housing of the data processing system based on a transient temperature behavior of the location inside of the housing; receiving, by the processor, temperature data from a temperature sensor located at the location inside of the housing; estimating, by the processor, the temperature of the target location on the housing of the data processing system based on the temperature data for the location inside of the housing using the thermal model; and initiating a signal, by the processor, in response to the estimated temperature of the target location being at or above a predetermined temperature, wherein the signal causes a reduction in the temperature of the target location on the housing.
