What is Heat exchanger?

A heat exchanger is a system used to transfer heat between two or more fluids. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

How to Calculate Heat exchanged?

Heat exchanged calculator uses Heat exchanged=Correction factor*Overall heat transfer coefficient*Area*Logarithmic mean temperature difference to calculate the Heat exchanged, The Heat exchanged formula is defined as the amount of heat transfer took place between the fluids in a heat exchanger. Heat exchanged and is denoted by Q symbol.

FAQ

What is Heat exchanged?

The Heat exchanged formula is defined as the amount of heat transfer took place between the fluids in a heat exchanger and is represented as Q=F*U*A*ΔTm or Heat exchanged=Correction factor*Overall heat transfer coefficient*Area*Logarithmic mean temperature difference. Correction factor is that is multiplied with the result of an equation to correct for a known amount of systematic error, Overall heat transfer coefficient is the overall convective heat transfer between a fluid medium (a fluid) and the surface (wall) flowed over by the fluid, The area is the amount of two-dimensional space taken up by an object and Logarithmic mean temperature difference is the log of mean of the temperature values.

How to calculate Heat exchanged?

The Heat exchanged formula is defined as the amount of heat transfer took place between the fluids in a heat exchanger is calculated using Heat exchanged=Correction factor*Overall heat transfer coefficient*Area*Logarithmic mean temperature difference. To calculate Heat exchanged, you need Correction factor (F), Overall heat transfer coefficient (U), Area (A) and Logarithmic mean temperature difference (ΔTm). With our tool, you need to enter the respective value for Correction factor, Overall heat transfer coefficient, Area and Logarithmic mean temperature difference and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
