Abstract:
1. An apparatus to control a temperature of a device, which apparatus comprises: a thermal head fluid path adapted to be in thermal contact with the device, the thermal head fluid path being disposed to receive thermal transfer fluid from a combined path and to output thermal transfer fluid fluidly to a pump assembly; a temperature sensor in communication with a controller and being operable to sense a temperature in response to the thermal head fluid path; the pump assembly being disposed to output the thermal transfer fluid fluidly to each of a first path, a second path, and a third path; the first path being fluidly connected at a first end to the output of the pump assembly and at a second end to the combined path, the first path being in thermal contact with a heating assembly; the second path being fluidly connected at a first end to the output of the pump assembly and at a second end to the combined path, the second path being in thermal contact with a cooling assembly; a third path being fluidly connected at a first end to the output of the pump assembly and at a second end to the combined path; and a first valve in the first path, a second valve in the second path, and a third valve in the third path; wherein: the first, second, and third valves are operable, in response to the controller, to control thermal transfer fluid flow through the first, second, and third paths.
