  2. Jacketed vessel - Wikipedia

    en.wikipedia.org/wiki/Jacketed_vessel

    They are slightly less efficient than dimple jackets because there is a double layer of metal for the heat to traverse (the plate coil inside surface and the vessel shell). They also require good bonding to the vessel jacket, to prevent an insulating gap between the plate coil and the vessel. Jackets can be applied to the entire surface of a ...

  3. 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.

    en.wikipedia.org/wiki/Run-around_coil

    A run-around coil installation, serving air handling units on the roof of an office building. A run-around coil is a type of energy recovery heat exchanger most often positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, to recover the heat energy. Generally, it refers ...

  6. 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

  9. Soldering - Wikipedia

    en.wikipedia.org/wiki/Soldering

    Induction soldering uses induction heating by high-frequency alternating current in a surrounding copper coil. This induces currents in the part being soldered, which generates heat because of the higher resistance of a joint versus its surrounding metal (resistive heating). These copper coils can be shaped to fit the joint more precisely.
