A plate type heat exchanger, as illustrated in Figure 2, consists of plates instead of tubes to separate the hot and cold fluids. The hot and cold fluids alternate between each of the plates. Baffles direct the flow of fluid between plates.

MECHANICAL DESIGN OF HEAT EXCHANGERS

Heat transfer equipment may be designated by type or function it performs, such as chiller, condenser, cooler reboiler, etc. The choice of shell and tube type is determined chiefly by factors such as the need for the provision for differential movement between shell and tubes, the design pressure, the design temperature, and the fouling nature of the fluids rather than the function. Merits and Demerits of Tube and Plate type Heat ExchangersMay 02, 2014 · Tube coolers may be preferred for lubricating oil cooling because of the pressure differential; Disadvantages. Heat transfer efficiency is less compared to plate type cooler; Cleaning and maintenance is difficult since a tube cooler requires enough clearance at one end to remove the tube nest; Capacity of tube cooler cannot be increased.

      Due to the high heat transfer efficiency of the plates, plate type heat exchangers are usually very small when compared to a tube and shell type heat exchanger with the same heat transfer capacity. Plate type heat exchangers are not widely used because of the inability to reliably seal the large gaskets between each of the plates.

Why Specify Plate And Frame Instead Of Shell And Tube The SUPERMAX® Shell And Plate Heat Exchanger is worthy of consideration for all duties with fluctuating temperature and pressure vs. bloc-type units. The reason is that welded heat exchangers with square/rectangular plates (the four corner grid design) suffer from thermal and pressure fatigue due to the weak corner welds. Shell and Tube or Plate Type? - Thermex Heat Exchangers Plate Heat Exchangers. Although the principals of Plate Heat Exchangers are very similar to Shell and Tube the construction is very different. Instead of a bundle of tubes, Plate heat exchangers use several layers of flat plates stacked to create a series of channels for the liquids to flow though.
