The utility model relates to a high-pressure liquid pipe deicing device for an exhibiting refrigerator, which is formed by that an evaporator (1), an air return pipe (9), a compressor (7), a condenser (6), a dry filter (8), a high-pressure liquid pipe (4) and a capillary pipe (3) are connected. After a refrigerant which comes from the evaporator (1) passes through the air return pipe (9), the refrigerant is compressed by the compressor (7), then passes through the condenser (6) and the dry filter (8), and finally the regrigerant reaches the high-pressure liquid pipe. The utility model is characterized in that a water box is fixed at the lower part of the evaporator (1) by a screw (14) and a pad piece (19), and the high-pressure liquid pipe (4) is arranged in the middle of the water box (5). Thereby, residual defrosting water is not iced in a refrigeration process, and the outer part of the water box is not condensed, which ensures that foods in the refrigerator are not influenced.
