Description
Technical Field
[0001] The utility model relates to the technical field of hot fluorine defrosting equipment, and particularly relates to a hot fluorine defrosting device for an air cooler. Background Technique
[0002] An air cooler is a heat exchange device that uses air as a cooling medium. It reduces the temperature of the hot fluid by allowing the hot fluid to exchange heat with the surrounding air, and is widely used in various industrial fields such as electric power, chemical industry, and metallurgy. The hot fluorine defrosting device is an energy-efficient defrosting system that directly heats the air cooler by using the heat released during the circulation of the refrigerant, quickly melting and removing the frost accumulated on the surface of the cooler due to low-temperature operation. By precisely controlling the flow rate and temperature of the refrigerant, the efficiency and automation of the defrosting process are achieved, effectively avoiding the problems of increased energy consumption and reduced cooling efficiency that may be brought about by traditional defrosting methods, and ensuring the continuous and stable operation of the air cooler under harsh environmental conditions.
[0003] However, when the existing hot fluorine defrosting devices are in use, most of them connect the drain pipes on the air cooler and the hot fluorine defrosting device with connecting pipes, allowing the high-temperature and high-pressure refrigerant in the hot fluorine defrosting device to enter the air cooler through the drain pipe and the connecting pipe to achieve the purpose of removing the frost layer on the air cooler. However, during the use of the air cooler, it will generate relatively large noise and vibration, and drive the connecting pipes installed on it to vibrate, causing the connecting pipes to shake on the drain pipe, which easily leads to gaps and leaks at the connection between the connecting pipes and the drain pipe, affecting the progress of the defrosting work. Therefore, the technical personnel in this field provide a hot fluorine defrosting device for an air cooler to solve the problems raised in the above background technique.
