The present invention relates to a freezing prevention device of a heat exchange unit for an air conditioning device including a freezing prevention and an anti-corrosion function. Specifically, the freezing prevention device of the heat exchange unit for an air conditioning device has a protection groove unit on a penetration part of a tube penetrating a partition to prevent the tube from being frozen since the penetration part is expanded when the tube is expanded. The freezing prevention device also prevents the tube part connected to a U-tube after protruding to the outside by passing through the partition from being frozen since a protection tube encloses the tube part. Moreover, the protection tube has a structure coming in contact with the partition instead of the tube since the protection tube is installed on the outer circumference of the tube. Thereby, electrical corrosion between dissimilar metals is generated in the protection tube instead of the tube, so the freezing prevention device can prevent the freezing or corrosion of the tube. |
