HEAT EXCHANGER PLATE AND PLATE HEAT EXCHANGER Russian patent published in 2014 - IPC F28F27/00 

FIELD: heating.

SUBSTANCE: heat exchanging plate for plate heat exchanger contains a heat transfer zone (10) and edge zone (11), extended around the heat transfer zone. The heat exchange plate is a plate with a double wall formed by two adjacent plates, compressed to be contacted with each other. The heat exchange plate contains the sensor (20), which is designed with a possibility of determination, at least, one parameter and output of the parameter-dependent signal, and the sensor has a sensor probe (21), designed to be located between adjacent plates.

EFFECT: improvement of leak detection in plate heat exchangers with the plates with double walls.
