Instrumented heat exchanger and method for estimating a lifetime of this heat exchanger

摘要

Heat exchanger (1) comprising:- several adjacent rectangular frames (2), each rectangular frame (2) defining an interior volume (4) in which a fluid is able to circulate,- a separation wall (5) arranged between each frame (2, 6) adjacent to and separating the interior volumes (4) from each other,- a closure wall (9) arranged on each rectangular end frame (6) and intended to close the interior volume (4) of said rectangular end frames (6),- a plurality of fluidic inlets (10), each in fluidic communication with an interior volume (4) and a plurality of fluidic outlets (31), each in fluidic communication with a volume (4) ) inside, said fluidic inlets (10) and outlet (31) being located on the rectangular frames (2), - at least one fluid distributor (11) arranged to distribute a fluid to at least a part of the fluidic inlets (10) , - at least one fluid manifold (12) arranged for glue cter a fluid leaving at least a part of the fluid outlets (31), - at least one temperature gauge (20) capable of measuring a temperature of the fluid, - at least one pressure gauge (21) capable of measuring a pressure of the fluid,- at least one strain gauge (22, 26, 27) capable of measuring a deformation on the heat exchanger (1),- a communication device (23) capable of receiving the measurements of the gauges (20, 21, 22, 26, 27) and send them to a computer processing unit (24).
