Tube bundle defect detection device and tube bundle defect detection method

The invention relates to a tube bundle defect detection device and a tube bundle defect detection method, and relates to the technical field of nondestructive detection.The tube bundle defect detection device and the tube bundle defect detection method have the advantages that an annular array probe is connected with a reflector, so that the tube bundle defect detection device can be inserted into a tube bundle from the end face of a shell-and-tube heat exchanger for nondestructive detection; the shell-and-tube heat exchanger does not need to be disassembled, so that the nondestructive testing efficiency of the shell-and-tube heat exchanger is improved; according to the tube bundle defect detection device, flaw detection sound waves emitted by the ring array probe can be vertically emitted to the inner surface of the tube bundle through the circular truncated cone reflection part, and the inner circumferential surface of the tube bundle can be covered, so that the whole inner circumferential surface of the tu
