Plate Type Heat Exchanger

In Heat exchanger system, the new and latest type of compact and effective model Heat exchanger is plate type heat exchanger. Another type of heat exchanger is the plate heat exchanger. One is composed of multiple, thin, slightly-separated plates that have very large surface areas and fluid flow passages for heat transfer. This stacked-plate arrangement can be more effective, in a given space, than the shell and tube heat exchanger. Advances in gasket and brazing technology have made the plate-type heat exchanger increasingly practical. In HVAC applications, large heat exchangers of this type are called plate-and-frame; when used in open loops, these heat exchangers are normally of the gasketed type to allow periodic disassembly, cleaning, and inspection. There are many types of permanently-bonded plate heat exchangers, such as dip-brazed and vacuum-brazed plate varieties, and they are often specified for closed-loop applications such as refrigeration. Plate heat exchangers also differ in the types of plates that are used, and in the configurations of those plates. The closely spaced metal heat transfer plates have troughs or corrugations, which induce turbulence to the liquids flowing as a thin stream between the plates. 

The plates have corner ports, which in the complete plate pack form a manifold for even fluid distribution to the individual plate passages. As an exclusive feature, parallel flow heat exchanger plates have interlocking gaskets in which upstanding lugs and scallops are sited intermittently around the outside edges. The seal between the plates is established by a peripheral gasket which also separates the thru port and flow areas with a double barrier. The interspaces are vented to atmosphere to prevent cross-contamination in the rare event of leakage. Plate heat exchanger, consists of a stationary head and end support connected by a top carrying bar and bottom guide rail. These form a rigid frame, which supports the plates and moveable follower.

  1. You really make it seem so easy with your presentation but I find this topic to be actually something
    which I think I would never understand. It seems too complex
    and very broad for me. I’m looking forward for your
    next post, I’ll try to get the hang of it!

  2. I am extremely inspired along with your writing abilities
    and also with the format on your blog. Is this
    a paid subject or did you modify it your self?
    Anyway keep up the nice quality writing, it
    is uncommon to look a great weblog like this one nowadays..

  3. Pretty nice post. I just stumbled upon your blog and wished
    to say that I have truly loved surfing around your weblog posts.
    After all I’ll be subscribing on your feed and I am hoping you write once more
    very soon!
