Plate heat exchanger liquid coolers

The plate heat exchanger, the refrigerant and cooling liquid flow through the channels formed in the Assembly of corrugated plates, or soldering or bolts as shown in Fig. 10. Plate heat exchanger evaporators can work on any dumped principle or by direct expansion. Most providers offer a separator for the separation of liquid and gas flooded type.

Advantages of plate heat exchanger liquid coolers over the shell-and-tube evaporators:

  • higher heat transfer coefficients;
  • the smaller the difference in temperature between the refrigerant and cooling fluid, which increases the boiling point, and, therefore, the improvement of the efficiency of the system;
  • more compact devices that require less plant room space;
  • less refrigerant;
  • the ability to clean, not soldered assemblies, thus maintaining a good heat transfer.
