Technical Field

[0001] The utility model relates to the technical field of cold dryers, in particular to an air-cooled cold dryer for atomic ash production. Background Art

[0002] Cold dryer is the abbreviation of refrigerated dryer. Cold dryer is a new technology, belonging to the air source processing component in the pneumatic system, which uses refrigerant to exchange heat with compressed air to reduce the temperature of compressed air to the dew point temperature in the range of 2-10°C. With the continuous development of the cold dryer industry, more and more companies are entering the air compressor industry, and more and more people are favoring the cold dryer industry. At the same time, many companies stand out. Cold dryers are divided into air-cooled and water-cooled types according to the cooling method of the condenser;

[0003] A Chinese patent with publication number CN218687412U was searched and disclosed a high-temperature air-cooled refrigerated dryer.
