A temperature control system comprises: an electric heater that has a first face which makes contact with an electronic device, and a second face which is opposite the first face; a heat sink, coupled to the second face of the heater, which absorbs heat from the electronic device through the heater's second face; and a temperature sensor, coupled to the electronic device which senses the device temperature T.sub.d. A control circuit is coupled to the device temperature sensor and to the heater; and it decreases the power to the heater when the sensed temperature of the electronic device is above the set point, and vice-versa. When the heater temperature T.sub.h is less than T.sub.d, then heat flows from the electronic device through the heater to the heat sink; and the rate of heat flow increases as T.sub.d -T.sub.h increases. When T.sub.h is more than T.sub.d, then heat flows to the electronic device from the heater; and the rate of heat flow increases as T.sub.h -T.sub.d increases.

[ What is claimed is:] [1.] A temperature control system which maintains the temperature of an electronic device near a set point temperature; said system comprising:an electric heater that has a first face for making contact with said electronic device, and a second face which is opposite said first face;a heat sink, coupled to said second face of said heater such that said heater is interposed between said heat sink and said electronic device:a temperature sensor, coupled to said electronic device; and,a control circuit, coupled to said temperature sensor and to said heater, which decreases the power to said heater when the sensed temperature of said electronic device is above said set point, and vice-versa;characterized in that due to said heater being interposed between said electronic device and said heat sink, the heat generated by said electronic device flows through said heater to said heat sink when the sensed temperature of said electronic device is at said set point under steady state conditions.
