ρ1 Problems to be Solved by the Invention In the above-mentioned conventional technology, an auxiliary cooler is provided on almost the entire lower surface of the projecting wall, and a refrigerant flow path is formed in this cooler over a wide area. The cooler tends to have too much excess cooling capacity, so the upper surface of the protruding wall of the insulating wall is cooler than the ambient temperature due to heat conduction from the auxiliary cooler, and the temperature gradually decreases to below the dew point. When the temperature reaches , dew is generated, and this dew becomes ice blocks due to the influence of the auxiliary cooler at night when the fluorescent lights are turned off, and especially when the outside temperature drops in winter, the ice blocks grow as they grow. There was a possibility that the condensate would block the dew drain and also prevent the opening and closing of the door. The present invention aims to solve the above problems.

) and the heat dissipation part (19B) to the upper plate □□□ will be reduced, and as a result, the temperature of the upper plate ■ can be kept higher than the dew point temperature, thus avoiding the overheating of the upper plate 4. You can do it. Also, when the outside air humidity is high, such as during the rainy season, dew forms on the top plate (A), and at that time, the lighting (C) is turned off and the radiant heat from the lighting (C) disappears. Also, the top board■
The temperature is kept higher than the freezing temperature, thereby avoiding freezing of the dew, and as a result, blocking of the drain pipe [F] by ice blocks and failure to open and close the transparent doors (3) and (4) can be avoided.

Since the present invention is a refrigeration showcase configured as described above, the lower surface of the projecting wall formed on the upper part of the heat insulating box has a heat exchange section where the refrigerant flows through the refrigerant flow path and is cooled, and a Since it is covered with an auxiliary cooler consisting of a heat radiating part through which cold heat is transmitted, the cold heat of the heat exchange part is transmitted to the heat radiating part and dispersed, and with this dispersion, overcooling of the upper part of the inside of the refrigerator can be avoided. In addition, the dispersion of the cold heat can alleviate the heat conduction from the heat exchange section and the heat radiation section to the upper surface of the projecting wall, and as a result, the projecting wall soil surface is maintained at a temperature higher than the dew point, and dew condensation can be avoided. Also, when the outside air humidity is high, such as during the rainy season, the temperature of the soil surface of the bulge falls below the dew point, and even if dew condensation occurs, the top surface of the bulge remains above the freezing temperature, thus preventing the dew from freezing. This results in better dew treatment.
