Vertical shell tube heat exchangers

About:

A vertical shell  tube heat exchangers  in which the tubes make longer through oversized holes in a liquid allotment plate. Liquid flows from end to end the holes and down each tube exterior surface as a falling film. A spacer or clip, desirably of wire, is positioned in each hole approximately each tube to center the tube so that the film has a uniform thickness. The clip is self-locking and remains fixed securely in position.It is a heat exchanger that is derived from its parent Shell and Tube Heat Exchanger and it is most commonly all Industries which involves higher-pressure and Higher Temperature applications.

               Shell and tube heat exchangers consist of a series of tubes. One set of these tubes contains the fluid that must be either heated or cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required. A set of tubes is called the tube bundle and can be made up of several types of tubes: plain, longitudinally finned, etc. Shell and tube heat exchangers are typically used for high-pressure applications (with pressures greater than 30 bar and temperatures greater than 260 °C).[2] This is because the shell and tube heat exchangers are robust due to their shape.

Specifications Vertical shell tube heat exchangers:

• It consist of a series of tubes. One set of these tubes contains the fluid that must be either heated or cooled.
• The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required.

Applications :

• This is widely used in variety of application as a cooling solution.
• The most common among them is for cooling of Hydraulic Fluid and oil in engines, transmissions and hydraulic power packs.
• With the right combination of materials they can also be used to cool or heat other mediums, such as swimming pool water or charge air.
• This  also be used on fixed tube sheet heat exchangers
