How Plate Heat Exchanger Works?
Plate heat exchangers consist of a number of corru¬gated plates. The plate pack is mounted between a fixed and movable pressure plate, positioned by an upper and lower carrying bar, and compressed by several tightening bolts. The media involved in the heat exchange process are fed into the plate pack via connections on the fixed and movable pressure plates.
The arrangement of the plates creates two separate channel systems, enabling the two media to flow past and between each other without physical contact, leaving the exchanger again via connections in the pressure plates. Plate with different patterns can be mixed in the heat exchanger in order to achieve optimum efficiency at a given pressure drop.
By install¬ing special distribution plates in the plate pack, the media can be conducted several times through the flow channel.
