Automatic washing apparatus for heat exchanger bundle

An automatic washing apparatus for a heat exchanger bundle, the automatic washing apparatus comprising:

• a chamber configured to accommodate the heat exchanger bundle therein and having a frame therein;
• an internal washing module disposed at a side of the frame, the internal washing module configured to move in X-axial, Y-axial, and Z-axial directions, and enabling washing water to be sprayed into tubes of the heat exchanger bundle;
• a camera configured to capture an image of the tubes of the heat exchanger bundle;
• and
• a control module coupled to the camera, and configured to receive the captured image of the tubes of the heat exchanger bundle, provide a map by setting coordinates of each of the tubes of the heat exchanger bundle, and control operation of the internal washing module based on the map,
• wherein the control module includes a computer for setting coordinates of the captured image, and a PLC for controlling the internal washing module on the basis of the coordinates transmitted from the computer and configured to correct a movement difference when an error is detected,
• wherein the computer is configured to identify insides of the tubes as holes from the captured image of the tubes of the heat exchanger bundle transmitted from the camera, calculate diameters of the holes and distances between the holes, and identify a hole as an error when the diameter of the hole is out of a predetermined tolerance range from an average value or is out of a predetermined tolerance range from an average value of the distances of the holes.
