Abstract
A plate heat exchanger comprising a first fluid (cooling media) supply channel and a first fluid discharge channel arranged though a heat plate package; with at least one second fluid (hot media) supply channel and at least one second fluid discharge channel also arranged through the heat plate package. The plate heat exchanger further comprises the addition of one or more auxiliary fluid heat exchange circuits including a conduit heat exchanger adapted to fit inside either the first fluid supply or discharge channels when acting as an after cooler, or the second fluid supply or discharge channel when acting as a pre-heater.
Claims23
A plate heat exchanger comprising
- a plurality of heat exchange plates including two end plates;
- a first liquid supply port through one of the end plates and in communication with a first liquid supply channel through the plurality of heat exchange plates;
- a first liquid discharge port connected through one of the end plates and in communication with a first liquid discharge channel through the plurality of plates;
