Water Heat Exchanger

A water heat exchanger is used by many companies for the purpose of transferring heat from one source to another and is widely used in space heating, refrigeration, power plants, chemical plants, natural gas processing and air conditioning. One of the most common examples of this device in motion is a radiator in a car. Being a hot engine-cooling fluid, the heat source transfers the heat to the air flowing through the radiator.

In the effort of transferring the heat from one fluid to another, the heat exchanger must all prevent the two fluids from being in contact with one another or from mixing using a solid wall. However, there are also designs that are customized to let the fluids be in direct contact with each other.

A water heat exchange utilizes the safest, most abundant and probably the safest source of fuel in the world—the water. Recent discoveries proved that water could run a car’s engine without the need for other gases thus minimizing the dependence on fossil fuel. There are three primary flow arrangements with heat exchangers: counter-flow, parallel-flow, and cross-flow.

In the counter-flow heat exchanger, the fluids enter the exchanger from opposite sides thus this is considered the most efficient design because it transfers the greatest amount of heat. In the parallel-flow heat exchanger, the fluids come in from the same end and move parallel to each other as they flow to the other side. The cross-flow heat exchanger moves the fluids in a perpendicular fashion.

A water heat exchanger is also known by other names for example in a car, the radiator that acts as an exchanger. The radiator cools the hot fluid by using the airflow over the surface of the radiator. Other examples of some uses for these devices are swimming pool heating, air conditioners, refrigerators and hot water radiators.
