  2. Pillow-plate heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Pillow-plate_heat_exchanger

    Pillow-plate heat exchangers are a class of fully welded heat exchanger design, which exhibit a wavy, “pillow-shaped” surface formed by an inflation process. Compared to more conventional equipment, such as shell and tube and plate and frame heat exchangers, pillow plates are a quite young technology. Due to their geometric flexibility ...

  3. Plate heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Plate_heat_exchanger

    The total rate of heat transfer between the hot and cold fluids passing through a plate heat exchanger may be expressed as: Q = UA∆Tm where U is the Overall heat transfer coefficient, A is the total plate area, and ∆Tm is the Log mean temperature difference. U is dependent upon the heat transfer coefficients in the hot and cold streams.

  4. Heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Heat_exchanger

    The heart of the heat exchanger contains a fully welded circular plate pack made by pressing and cutting round plates and welding them together. Nozzles carry flow in and out of the platepack (the 'Plate side' flowpath). The fully welded platepack is assembled into an outer shell that creates a second flowpath (the 'Shell side').

  5. Plate-fin heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Plate-fin_heat_exchanger

    A plate-fin heat exchanger is made of layers of corrugated sheets separated by flat metal plates, typically aluminium, to create a series of finned chambers. Separate hot and cold fluid streams flow through alternating layers of the heat exchanger and are enclosed at the edges by side bars. Principal Components of a Plate Fin Heat Exchanger

  6. Jacketed vessel - Wikipedia

    en.wikipedia.org/wiki/Jacketed_vessel

    These so-called dimples impart turbulence to the heating or cooling media as it flows through the jacket (see Pillow plate heat exchanger). Plate Coils. Often very similar to dimple jackets, but fabricated separately as fully contained jackets that are then strapped to a vessel. They are slightly less efficient than dimple jackets because there ...

  9. Continuous cooling transformation - Wikipedia

    en.wikipedia.org/wiki/Continuous_cooling...

    These diagrams are used to represent which types of phase changes will occur in a material as it is cooled at different rates. These diagrams are often more useful than time-temperature-transformation diagrams because it is more convenient to cool materials at a certain rate (temperature-variable cooling), than to cool quickly and hold at a ...
