PLATE HEAT EXCHANGER: DEFINITION AND FUNCTION
Plate heat exchangers, also known as plate coolers, are used to transfer heat between two media – for example fluids, which are separated from another via a solid wall. The plate heat exchanger consists of different heat transfer plates that are screwed, brazed or welded together by laser.
The heat exchanger’s individual transfer plates are arranged in packages, which form flow gaps through which the hot and cold media alternatingly flow. This enables the thermal energy to transfer from one medium to the other. Here it´s essential that the two media are securely sealed off to not mix. Whenever the heat exchanging media flow in opposite directions, as is usually the case, we speak of the countercurrent principle. Otherwise, the parallel flow principle. Some fully-welded models may also apply the cross-flow principle. Here, a special corrugation of the transfer plates ensures a highly turbulent flow behavior.
Plate heat exchanger: construction and application
In principle, our plate heat exchangers function similarly. Depending on the purpose for which the heat exchanger is needed, they may differ in configuration, structure and materials used. In addition to the brazed plate design, the bolted plate design is frequently used for sealed plate heat exchangers. Here the advantage is that the design is compact and without seals.
A typical use for plate heat exchangers, for example, is in heating units, as they separate systems from another to protect the boiler from oxygen.
Further examples of application areas are:
- heating technology, e.g. underfloor heating, solar systems or DHW heating
- industry, e.g. in power plants or in mechanical engineering
- food technology, e.g. for cooling milk or for pasteurizing beer
- refrigeration and cooling technology, e.g. as a condenser, evaporator or superheater
