1. A heat exchanger, comprising:
a plurality of sets of heat exchange tubes positioned adjacent each other, wherein the plurality of sets of heat exchange tubes includes a first set of heat exchange tubes and a second set of heat exchange tubes, each set of heat exchange tubes is fluidly coupled to at least one end of a respective header, and an end of the header of the first set of heat exchange tubes includes a baffle extending therefrom;
a sensor grid positioned amongst the plurality of sets of heat exchange tubes, the sensor grid including a plurality of sensors, each sensor including a sensor lead extending therefrom;
a conduit extending through the baffle, the conduit including a plurality of sensor leads of the sensor grid extending therethrough; and
a tube restraint for positioning at least one of the plurality of sets of heat exchange tubes relative to an enclosure, the tube restraint including a tube opening for each of the heat exchange tubes of a respective set of heat exchange tubes and a sensor lead opening,
wherein at least one sensor lead of the sensor grid extends through the sensor lead opening.
