Problems solved by technology
The conventional evaporative air cooler adopts a bare tube structure, sprays desalted water on the upper part, and uses the surface water to evaporate and absorb heat to lower the temperature; because the conventional evaporative air cooler adopts a bare tube structure, its heat transfer area is small, and desalinated water needs to be sprayed throughout the year (Currently improved evaporative air coolers only have a water saving rate of 30% without spraying water in winter), so the evaporative cooling process still consumes a lot of desalted water
Therefore, there is an urgent need for water-saving air cooling technology and equipment under the current requirement of substantial water saving, and to solve the problem of poor cooling effect of conventional air coolers in summer

The invention discloses a cooling method, belongs to the technical field of water saving, energy conservation, environmental protection and process equipment, and solves the problems of high factory water consumption and weak cooling effect of conventional air coolers in summer. The cooling method comprises the following steps: air enters to exchange heat with a process medium by a finned tube; and high-temperature air is exhausted. The cooling method is characterized by being operated by two modes; in summer, water is sprayed above the finned tube to wet the surface of the finned tube; the heat absorption through water evaporation is used for creating a low-temperature environment to reinforce the summer cooling capacity of an air cooler; in spring, autumn and winter, water is not sprayed; the process medium is adopted to exchange heat with low-temperature air through the finned tube; and the operation of assisting two modes by an auxiliary air window is designed to realize annular factory saving of more water. The invention further provides a finned tube bundle, a water spraying facility and auxiliary air window equipment for realizing the method. The cooling method is used for northern and dry regions, reaches the annular water saving rate of 50-80%, and solves the problem of weak cooling effect of the air cooler in summer.
Description
technical field [0001] The invention belongs to the technical fields of water saving, energy saving, environmental protection and process equipment, and in particular relates to a cooling method and a double-mode finned tube air cooler. Background technique [0002] Industrial processes often involve process medium cooling. Usually, circulating water coolers and air coolers are used to cool the process medium at 60-120°C to 35-40°C. According to comprehensive calculations, air cooling is more energy-saving, water-saving and environmentally friendly than circulating water cooling. [0003] The air temperature in winter, spring and autumn in the northern region is low (-10-20°C). The process medium can be cooled to 35-40°C by using a dry air cooler. The cooling process does not consume water, so making full use of low-temperature air cooling is the first choice for water saving in the northern region. . However, the air temperature in summer is high (the hottest month reaches...
