A heat exchanger is a piece of equipment built for efficient heat transfer from one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact.[1] They are widely used in space heating, refrigeration, air conditioning, power plants, chemical plants, petrochemical plants, petroleum refineries, natural gas processing, and sewage treatment. One common example of a heat exchanger is the radiator in a car, in which the heat source,Choose plate heat exchanger being a hot engine-cooling fluid, water, transfers heat to air flowing through the radiator (i.e. the heat transfer medium)

Heat Exchangers Online is a supplier of heat exchangers and other related products for the HVAC and process industries. We provide low maintenance and durable heat exchangers with unique designs and high heat transfer rates. Not only will our heat exchangers work for your industrial or residential environment, however severe the conditions, they will require very little maintenance to continue doing so - saving you considerable time and money.

"Heat exchanger refers to the device transferring heat from hot fluid to cold fluid so as to meet specific technique requirement, which is an industrial application of convective heat transfer and heat transmission. Several approaches can be used for classification of heat exchangers, including the classification by action principles, purposes, materials, etc. As heat transfer equipment, heat exchangers are widely used in industries, especially for those fields with huge energy consumption, and contain increasingly more varieties with the rapid development of energy-saving technology.

There are two 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 design is most efficient, in that it can transfer the most heat from the heat (transfer) medium. See countercurrent exchange. In a cross-flow heat exchanger, the fluids travel roughly perpendicular to one another through the exchanger.

What are heat exchangers? They are devices specifically designed for the efficient transfer of heat from one fluid to another fluid over a solid surface.cheap wedding dresses This transfer of heat can either take the form of absorption or dissipation of heat. Heat exchangers can be found in everyday equipment from boilers, furnaces, refrigerators to air conditioning systems.
