Terminal device used in refrigerating chamber

The utility model relates to a terminal device used in a refrigerating chamber. The terminal device comprises an air-cooler mounted at the top of the refrigerating chamber and a water receiving plate mounted at the lower end of the air-cooler, and is characterized in that an insulating case body is arranged at the upper end of the top of the refrigerating chamber; the air-cooler is mounted in the insulating case body; and an air intake hole and an air return hole are formed at the top of the refrigerating chamber, wherein the air intake hole is communicated with an air outlet of a fan of the air-cooler through an air flue and the fan of the air-cooler is connected to the air outlet of the air-cooler through an air flue, and the air return hole is communicated with an air inlet of the air-cooler through an air flue. By adopting the structure, the cooling performance is good, the refrigerating chamber space is saved, the space utilization rate of the refrigerating chamber is improved, the maintenance cost is reduced, the production efficiency is improved, and the construction cost and the maintenance cost of the refrigerating chamber are reduced.
