Abstract
A method for thermographic analysis of a heat exchanger comprises: applying vibrations to the heat exchanger as a part of a vibration testing process; capturing a thermographic image of at least a portion of the heat exchanger whilst the heat exchanger is undergoing vibrations; analysing the thermographic image; and determining a status of the heat exchanger based on the analysis of the image.
Claims10
A method for thermographic analysis of a heat exchanger, the method comprising:
- applying vibrations to the heat exchanger with a source of vibrations as a part of a vibration testing process;
- capturing a thermographic image of at least a portion of the heat exchanger whilst the heat exchanger is undergoing vibrations;
- analysing the thermographic image;
- determining a status of the heat exchanger based on the analysis of the image;
- wherein determining a status of the heat exchanger includes comparing at least one feature of the captured thermographic image with a library of heat exchanger defects to classify the at least one feature of the thermographic image based on that comparison;
- and
- updating the library of heat exchanger defects based on the captured thermographic image.
A system for thermographic analysis of a heat exchanger, the system comprising:
- a source of vibrations for applying vibrations to the heat exchanger as a part of a vibration testing process;
- an imaging device for capturing a thermographic image of at least a portion of the heat exchanger whilst the heat exchanger is undergoing vibrations;
- and
- a data processor for analysing the thermographic image and for determining a status of the heat exchanger based on the thermographic image, wherein when determining a status of the heat exchanger the data processor compares at least one feature of a captured thermographic image with a library of defects to classify the at least one feature of the captured thermographic image based on that comparison and updating the library based on the captured thermographic image.
A computer program product comprising instructions stored on a non-transitory medium for execution on a system for thermographic analysis of a heat exchanger, the system comprising a source of vibrations for applying vibrations to the heat exchanger as a part of a vibration testing process;
- an imaging device for capturing a thermographic image of at least a portion of the heat exchanger whilst the heat exchanger is undergoing vibrations;
- and a data processor, the instructions, wherein when executed on the system causing the system to:
- capture a thermographic image of at least a portion of the heat exchanger whilst vibrations are being applied to the heat exchanger, analyse the thermographic image;
- determine a status of the heat exchanger based on the analysis of the image, wherein determining a status of the heat exchanger includes comparing at least one feature of the captured thermographic image with a library of heat exchanger defects to classify the at least one feature of the thermographic image based on that comparison;
- and
- update the library of heat exchanger defects based on the captured thermographic image.
