Introduction
Operating Principle
The operating principle of the heat exchanger is based on liquid-to-liquid
transfer of heat (
Figure P.1
). The drive loop transports the heat load from the
drive to the heat exchanger. The supply loop flows through the heat
exchanger to collect the heat load and transports it to the user’s cooling
system liquid source. The use and choice of a system for disposing of the
heat load is the user’s responsibility.
Figure P.1 Liquid Flow Heat Transfer Diagram
The liquid-to-liquid heat exchanger uses a heat transfer plate to transfer heat
from one liquid to another. This method requires a stable water supply from
the user.
