Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine construction, in particular to a novel cooling device for a nitrogen generator. Background Art
[0002] At present, the new nitrogen generator in the mine is usually cooled by an air cooling system. Its working principle is to inhale the air in the environment into the nitrogen generator, and then use the internal compressor to compress the air. At the same time, the compression will generate heat. Then, through the air cooling system, the compressed air passes through the radiator, and the air is brought into contact with the radiator surface by a fan or natural wind to dissipate the heat and cool the air to the required temperature. Finally, the cooled air is separated into nitrogen through a separation device to realize the nitrogen production process. However, this air-cooled heat dissipation structure will cause the temperature of the nitrogen production chamber to be high during the operation of the equipment when used for a long time. Long-term operation is easy to cause damage to the equipment components. The high temperature environment caused by the air-cooled heat dissipation structure will damage the equipment and reduce performance, which will affect the normal operation and production efficiency of the nitrogen generator.
