A shell-and-tube heat exchanger is a class of heat exchanger designs. [1] [2] It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes ...
Because heat exchangers can be configured many different ways, TEMA has standardized the nomenclature of exchanger types. [13] A letter designation is used for the front head type, shell type, and rear head type of an exchanger. For example, a fixed tubesheet exchanger with bolted removable bonnets is designated as a 'BEM' type.
However, since double pipe heat exchangers are simple, they are used to teach heat exchanger design basics to students as the fundamental rules for all heat exchangers are the same. 1. Double-pipe heat exchanger When one fluid flows through the smaller pipe, the other flows through the annular gap between the two pipes.
Concentric Tube (or Pipe) Heat Exchangers are used in a variety of industries for purposes such as material processing, food preparation, and air-conditioning. [1] They create a temperature driving force by passing fluid streams of different temperatures parallel to each other, separated by a physical boundary in the form of a pipe.

Diagram showing components and mechanism for a heat pipe containing a wick Heat pipes keep ground frozen and inhibit water transfer into the open pit during mining activities at Ekati Diamond Mine This 100 mm by 100 mm by 10 mm high thin flat heat pipe (heat spreader) animation was created using high resolution CFD analysis and shows temperature contoured flow trajectories, predicted using a ...
It is used in some household stoves [1] and in some industrial process vessels (tanks), such as shell and tube heat exchangers, chemical reactors, and static mixers. Baffles are an integral part of the shell and tube heat exchanger design. A baffle is designed to support tube bundles and direct the flow of fluids for maximum efficiency.
Bottom end of a downhole heat exchanger Top end of a downhole heat exchanger. A downhole heat exchanger, (DHE) also called a borehole heat exchanger, (BHE) is a heat exchanger installed inside a vertical or inclined borehole. [1] It is used to capture or dissipate heat to or from the ground. DHT's are used for geothermal heating, sometimes with ...
