AI Technical Summary
In existing refrigerators, defrosting water tends to remain on the fins during the defrosting process, which reduces the heat exchange efficiency between the fins and the refrigerator interior.
A first guide groove and a guide plate are set on the fins of the evaporator. The guide groove is set at an acute angle to the horizontal plane. Through the cooperation of the guide groove and the guide plate, the surface tension of the defrost water is broken, so that the defrost water accumulates in the groove and is guided away from the evaporator.
It effectively reduces defrost water residue, prevents defrost water from condensing again, improves the heat exchange efficiency of the fins, and reduces the space occupied by defrost water inside the refrigerator.
