Abstract: A heat exchanger unit that includes a frame and an at least one cooler coupled therewith. The heat exchanger unit has a reference axis. The heat exchanger unit includes an airflow region therein. The heat exchanger unit includes an at least one baffle coupled to the frame within the airflow region. The at least one baffle is configured at an angle to the axis.

Abstract: Embodiments of the disclosure pertain to a method for monitoring a heat exchanger unit that may include the steps of: associating a monitoring module with an airflow side of the heat exchanger unit; operating the monitoring module whereby a microcontroller performs tasks related to data acquisition, data comparison, and providing an indication; and taking an action based on the indication. The monitoring module includes an at least one sensor proximate to the airflow side; a logic circuit in operable communication with the at least one sensor, and further comprising the microcontroller.

Abstract: A monitored heat exchanger system that includes a heat exchanger unit in operable engagement with a heat generating device, with an at least one service fluid being transferable therebetween, and a monitoring module coupled to the heat exchanger unit. The monitoring module includes a primary microcontroller in operable communication with an at least one sensor assembly. The at least one sensor assembly includes a mounting frame; a support platform; a circuit board; an inner sensor housing configured to extend out and around the circuit board and the support platform; a first magnet coupled to an underside of the inner sensor housing; and a rotating member comprising a plurality of blades, the rotating member being disposed on top of the inner sensor housing.
