Defect detecting device of evaporator tube and production system of wound tube type evaporator

The utility model provides a defect detecting device of an evaporator tube and a production system of a wound tube type evaporator. The defect detecting device of the evaporator tube comprises a straightening machine used for straightening the evaporator tube, a flaw detector used for carrying out defect detection on the evaporator tube straightened by the straightening machine, and a prompting device connected to the flaw detector and used for informing a user of the detection result of the flaw detector on the evaporator tube. According to the technical scheme, when the evaporator is manufactured in a pipe winding mode, the defect of the evaporator tube can be detected before the evaporator tube is wound on an inner container of a refrigerator, a defective aluminum tube is effectively prevented from being used on the evaporator of the refrigerator or a freezer, the quality of wound tube type evaporator products is improved greatly, and the problem that as tubes with a leakage defect are used on the refrigerator or the freezer with the wound pipe type evaporator, refrigeration can not be achieved can be effectively prevented.
