A temperature control system comprises a reservoir that is holding a hot fluid; a heat exchanger, for an electronic component, coupled to an input conduit that carries the hot fluid from the reservoir into the heat exchanger; an output conduit coupled to the heat exchanger, that carries the hot fluid from the heat exchanger back to the reservoir; a first temperature sensor, coupled to the input conduit; and a second temperature sensor, coupled to the output conduit. A heater is coupled to the output conduit which adds heat to the hot fluid in the output conduit in response to a heater control signal; and a cooler is coupled to the reservoir which adds cold fluid to the reservoir in response to a cooler control signal. A temperature controller generates the heater control signal and the cooler control signal as respective functions of both sensed temperatures.

1. A temperature control system, comprising:a reservoir that is holding a hot fluid; a heat exchanger adapted to contact an electronic component, said heat exchanges being coupled to an input conduit that carries said hot fluid from said reservoir into said heat exchanger; and an output conduit which is coupled to said heat exchanger, said output conduct carrying said hot fluid from said heat exchanger back to said reservoir; a first sensor, coupled to said input conduit, having a signal terminal which generates an input temperature signal that indicates the temperature of said hot fluid flowing into said heat exchanger; a second sensor, coupled to said output conduit, having a signal terminal which generates an output temperature signal that indicates the temperature of said hot fluid flowing out of said heat exchanger; a heater, coupled to said output conduit, having a control input that receives a heater control signal and, in response thereto, adds heat to said hot fluid that is returning back to said reservoir in said output conduit; a cooler, coupled to said reservoir, having a control input that receives a cooler control signal and, in response thereto, adds a cold fluid to said hot fluid in said reservoir; and, a temperature controller having input terminals that receive said input temperature signal and said output temperature signal, and having an electronic circuit that generates said heater control signal and said cooler control signal as respective functions of both said temperature of said hot fluid flowing into said heat exchanger and said temperature of said hot fluid flowing out of said heat exchanger.
