WebThe performances of a heat exchanger can be readily evaluated if the number of transfer units is known. The number of transfer units (NTU = UA / ( mcp )) itself is a combination of overall heat transfer coefficients, transfer area, fluid flow rate and heat capacity. It summarizes these dimensional parameters into one dimensionless parameter. WebThe heat exchanger is a coil of tubing in the storage tank. It can be a single tube (single-wall heat exchanger) or the thickness of two tubes (double-wall heat exchanger)), depending on the heat transfer fluid. . A less efficient alternative is to place the coil on the outside of the collector tank with a cover of insulation.

HEAT EXCHANGERS

WebA heat exchanger is a device, which transfers thermal energy between two fluids at different temperatures. In most of the thermal engineering applications, both of the fluids are in motion and the main mode of heat … WebAs its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids.
