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.
Heat exchangers are devices designed to transfer heat between two or more fluids—, liquids, vapors Further detail on how these components function within a heat exchanger will be provided in the next Size Limitations. After choosing the optimal type and design of a heat exchanger,
Sizing of heat exchangers is done based on the required surface area for heat transfer. There is a design equation (a power law with exponent ) for heat exchangers that can found in the textbook by Peters, Timmerhaus, and West entitled "Plant Design and Economics for Chemical
Lets assume an exchanger that is 100% efficient (no heat loss). Duty (Q) and LMTD is known. Your overall heat transfer coefficient (U) is dependent on Related Threads on How to size a heat exchanger?

How to calculate a heat exchanger. Starting from the definition of the heat exchanger, the key task for the designer is the sizing of the heat exchanger. The critical issue when designing the heat exchanger is the determining of the thermal exchange coefficients reliably and accurately: a
Two fluids can exchange heat, one fluid flows over the outside of the tubes while the second fluid flows through the tubes. In a fixed tubesheet exchanger, the tubesheet is welded to the shell. This results in a simple and economical construction and the tube bores can be cleaned mechanically or chemically.
These heat exchangers are comprised of multiple metal plates that are typically gasketed together and mounted onto a frame. P&F heat exchangers have high U factors (1000 units or more) thanks to the turbulence produced by the many tight directional changes in the plated channels.
