It works by transferring heat from the hot oil to a cooling medium, either air or a liquid like coolant, which then carries the heat away.
. Double-pipe heat exchanger When one fluid flows through the smaller pipe, the other flows through the annular gap between the two pipes. These flows may be parallel or counter-flows in a double pipe heat exchanger. (a) Parallel flow, where both hot and cold liquids enter the heat exchanger from the same side, flow in […]

There are three primary classifications of heat exchangers according to their flow arrangement. In parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side. In counter-flow heat exchangers the fluids enter the exchanger from opposite ends. The counter current...
