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.

A radiator arrangement for a motor vehicle the motor vehicle is driven by an internal combustion engine or at least partially electrically, with a first heat exchanger that is connected to a coolant circuit of the motor vehicle; and with a second heat exchanger that is connected to a refrigerant circuit of the motor vehicle. With respect to a main direction of an air flow through the radiator arrangement, the first heat exchanger is arranged in front of the second heat exchanger, and a first base area of the first heat exchanger that is exposed to the air flow is smaller than a second base area of the second heat exchanger that is exposed to the air flow. The first base area is dimensioned such that it overlaps the second base area only in an inlet-side region with respect to the refrigerant flow in the second heat exchanger.

A flow control baffle apparatus for a vehicle heater is provided. The flow control baffle apparatus implements a flow control function of a fluid passing through the interior of a heater and improves the heat transfer performance of the heater. The flow control baffle apparatus for a vehicle heater includes a plurality of heater pipes that are disposed within the interior of a heater and a baffle pivotably disposed at both sides of the heater pipe to adjust the flow of a fluid. Wherein the baffle adjusts the flow rate of a fluid passing through the heater.

The present invention relates to a cooling module including a first radiator, and a second radiator stacked and disposed at an upstream side of the first radiator based on a flow direction of cooling air, in which the first radiator includes a main inlet port connected to an engine so that a coolant is introduced through the main inlet port, a main discharge port through which the coolant is discharged, an auxiliary discharge port connected to a third radiator, which is installed at a position that does not overlap the first radiator and the second radiator in the flow direction of the cooling air, so that the coolant is discharged through the auxiliary discharge port, and an auxiliary inlet port through which the coolant is introduced, such that the first radiator may be easily connected to the third radiator, which may improve cooling performance.
