Therefore a plate type heat exchanger, as compared to a similarly sized tube and shell heat exchanger, is capable of transferring much more heat. This is due to the larger area the plates provide over tubes. Due to the high heat transfer efficiency of the plates, plate type heat exchangers are usually very small when compared
A shell and tube heat exchanger (STHE) provides a comparatively large ratio of heat transfer area to volume and weight in a form, which is relatively easy to construct in a wide range of sizes, whereas it is mechanically rugged enough to withstand normal shop fabrication, shipping and field erection stresses. Understanding what makes one heat exchanger unique from another is often difficult, so this article will help readers gain an introductory knowledge on one of the most popular heat exchangers, the shell and tube heat exchanger. This article aims to reveal what shell and tube heat exchangers are, how they work, what types exist, and how they are ...
In this design, the outer tube sheet is outside the shell circuit, virtually eliminating the chance of fluid intermixing. The inner tube sheet is vented to atmosphere so any fluid leak is easily detected. Other Pages about Heat Exchangers. Part 1: Heat Transfer and types of Heat Exchangers. Part 2: Shell and Tube Heat Exchangers.
According to some estimates, heat transfer coefficients with the twisted-tube design are 40% higher than those found in a conventional shell-and-tube heat exchanger with a similar pressure reduction. Heat exchanger design includes estimation of the heat transfer area needed for known or estimated heat transfer rate, overall heat transfer coefficient and log mean temperature difference. The tube or pipe diameters and length also need to be determined, as well as the pressure drop.
Heat transfer equipment may be designated by type or function it performs, such as chiller, condenser, cooler reboiler, etc. The choice of shell and tube type is determined chiefly by factors such as the need for the provision for differential movement between shell and tubes, the design pressure, the design temperature, and the fouling nature of the fluids rather than the function.
