Summary:

Plate heat exchangers come in two types: frame type (removable heat exchangers) and brazed type. The three types of plates are herringbone corrugated plates, horizontal smooth plates, and nodular plates.


  What are the basic structures of a plate heat exchanger?

  There are two types of plate heat exchangers: frame type (removable heat exchanger) and brazed type. The three types of plates are herringbone corrugated plates, horizontal smooth plates, and nodular plates.

  Brazed heat exchanger structure

  Main structure

  1. Plate heat exchanger plates and sealing gaskets

  2. Fixed compression plate

  3. Movable compression plate

  4. Clamping bolts

  5. Upper guide rod

  6. Lower guide rod

  7. Rear column

  It consists of a set of stacked plates forming a channel-type plate package. End bottom plates with connecting pipes are configured at both ends.

  The entire machine is made by vacuum brazing. Adjacent channels flow two different media. The plates between adjacent channels are pressed into a corrugated shape to enhance the heat exchange between the two media. In brazed plate heat exchangers for refrigeration, the water flow channel is always one more than the refrigerant flow channel.
