A HEAT EXCHANGER PLATE AND A PLATE HEAT EXCHANGER

摘要

The invention refers to a heat exchanger plate and a plate heat exchanger. The heat exchanger plates are arranged beside each other in the plate heat exchanger to define several first plate interspaces for a first medium and several second plate interspaces for a second medium. The heat exchanger plate comprises a heat transfer area (10), an edge area (11), which extends around and outside the heat transfer area (10), and a device (25), which is configured to receive or produce a signal. The heat exchanger plate also comprises a communication module (20) comprising an electronic circuit (21) connected to the device and communication means permitting communication of said signal with a master unit (30) via at least a communication module (20) of another heat exchanger plate in the plate package.
