1. A temperature control assembly, comprising:
a cold plate having a first contact surface and a second contact surface opposite the first contact surface, wherein the cold plate is composed of a thermally conductive material;
a channel formed in the cold plate and enclosed by the cold plate between the first contact surface and the second contact surface of the cold plate;
an inlet formed in the channel for providing inflow of a liquid to the channel;
an outlet formed in the channel for providing outflow of the liquid from the channel;
at least one aperture formed in the cold plate, wherein the aperture receives an electrical connection between a printed circuit board when the printed circuit board is coupled to the first contact surface of the cold plate and a photodetector assembly when the photodetector assembly is coupled to the second contact surface of the cold plate;
a thermally conductive pad coupled to the second contact surface;
a heating element coupled to the thermally conductive pad; and
a temperature sensor that measures a temperature of electrical components mounted to the printed circuit board when the printed circuit board is coupled to one of the first contact surface or the second contact surface, and wherein the temperature sensor provides the measured temperature to a controller in order to control a power supplied to the heating element.
