Heat Exchangers - High-efficiency Countercurrent Design Optimal Heat Transfer With Parallel And Cross-flow Capabilities

Hot plate used in heat exchange Heat exchangers are devices whose
primary   responsibility is the transfer (exchange) of heat typically
from one fluid to another. However they are not only used in heating
applications such as space heaters but are also used in cooling
applications such as refrigerators and air conditioners. Many types of
heat exchangers can be distinguished from on another based on the
direction the liquids flow. In such applications the heat exchangers
can be and be parallel-flow cross-flow or countercurrent. In
parallel-flow heat exchangers both fluid involved move in the same
direction entering and exiting the exchanger side by side. In
cross-flow heat exchangers the fluid paths run perpendicular to one
another. In countercurrent heat exchangers the fluid paths flow in
opposite directions with each exiting where the other enters.
Countercurrent heat exchangers tend to be more effective than other
types of exchangers.
