Description
technical field [0001] The present application relates to the technical field of non-destructive testing of heat exchange equipment, in particular to a heat exchanger plate crack detection device and a crack detection method thereof. Background technique [0002] The plate heat exchanger is a high-efficiency heat exchanger that is arranged by a series of metal corrugated plates with a certain corrugated shape and exchanges heat through the metal corrugated plates. Compared with other heat exchangers, the plate heat exchanger has compact structure and high heat exchange efficiency, and has been widely used in petroleum, chemical industry, metallurgy, shipbuilding, machinery, electric power, food, pharmaceutical and other fields. [0003] The corrugated plate in the plate heat exchanger is a component that is specially responsible for isolating the heat transfer medium and performing heat exchange, and is the core component of the heat exchanger. In order to ensure the qualit...
