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 ...
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 sodium-calcium exchanger (often denoted Na + /Ca 2+ exchanger, exchange protein, or NCX) is an antiporter membrane protein that removes calcium from cells. It uses the energy that is stored in the electrochemical gradient of sodium (Na +) by allowing Na + to flow down its gradient across the plasma membrane in exchange for the countertransport of calcium ions (Ca 2+).

The origins of the NBTC stem from the 1997 constitution, which envisioned transmission frequencies as a public resource to be regulated by an independent body serving the public interest. Parliamentary acts issued in 2000 in accordance with the constitution called for the creation of a National Telecommunications Commission (NTC) and a National ...
Baffle (heat transfer) Baffles are flow-directing or obstructing vanes or panels used to direct a flow of liquid or gas. 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 ...
The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. Welded, semi-welded and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required. In place of a pipe passing through a chamber, there are instead two ...
The anion exchanger family ( TC# 2.A.31, also named bicarbonate transporter family) is a member of the large APC superfamily of secondary carriers. [1] Members of the AE family are generally responsible for the transport of anions across cellular barriers, although their functions may vary. All of them exchange bicarbonate.
