Which type of heat exchanger an automobile radiator is?

Which type of heat exchanger an automobile radiator is? Correct Answer Cross flow type

Explanation:

Cross-flow:

It is a cross-flow type. As the air flows perpendicular to the water flow in this type of configuration and the same mechanism is occurring in an automobile radiator.

Parallel flow:

When the fluids enter and leave at the same end as it is in concentric tube arrangement then the flow is known as parallel-flow.

Counterflow:

In the counterflow configuration, the fluids enter and leave at the opposite end.
