temperature regulation system for an electronic circuit in which the temperature of a heat source and a heat sink, the temperature is estimated

摘要

The present invention relates to a temperature control system which maintains the temperature of an electronic device near a set point temperature and including: an electric heater (13) that has a first face (13a) for making contact with said electronic device (11), a second face (13b) which is opposite said first face (13a), a heat sink (14) which is coupled to said second face (13b) of said heater (13) such that said heater (13) is interposed between said heat sink (14) and said electronic device (11); and means for determining the temperature of the electronic device (11), preferably implemented as a temperature sensor (12c), further characterized by a control circuit (15), coupled to said means for determining the temperature of the electronic device and to said heater (13), which decreases the power to said heater (13) when the temperature of said electronic device (11) is above said set point, and vice-versa.
