Helically coiled tube with secondary flow. The coil spring insert may enhance heat transfer without turbulence or additional heat transfer surface area. A secondary flow is induces the fluid creating two longitudinal vortices. This could result, (in contrast to a right tube) in highly non-uniform local around the periphery of the tube.
In shell-and-tube heat exchangers there is a potential for a tube to rupture and for high pressure (HP) fluid to enter and over-pressurise the low pressure (LP) side of the heat exchanger. [8] The usual configuration of exchangers is for the HP fluid to be in the tubes and for LP water, cooling or heating media to be on the shell side.
Tubular heat exchanger Partial view into inlet plenum of shell and tube heat exchanger of a refrigerant based chiller for providing air-conditioning to a building. A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. [1]
The member companies of TEMA must demonstrate high quality exchanger fabrication standards, and possess in-house engineering capability for mechanical and thermal design of shell and tube type heat exchangers. Companies may fabricate other equipment in addition to heat exchangers. The current member companies of TEMA (in alphabetical order) are:
Size Reduction: If the heat exchange rate (Q) is held constant the heat exchanger length may be reduced. This will provide a smaller heat exchanger. Increased heat exchange rate: This may be exploited either of two ways: Reduced driving temperature difference (ΔTm): If Q and the total tube length (L) are held constant, the ΔTm may be reduced.
A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. [1] [2] [3] These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure. Where cooling water is in short supply, an air ...
An applicable technologies for indirect heat transfer use tubes (shell-and-tube exchangers) or flat surfaces (plate exchangers).Their goal is to exchange the maximum amount of heat per unit area by generating as much turbulence as possible below given pumping power limits.
