[Background technology]

[0002] my country's economy has been developing rapidly in recent years, and the supply of electricity has become increasingly tight. Therefore, it is imperative for the power industry to accelerate the development of large-capacity steam turbine units. The power industry not only consumes a large amount of primary energy, but also consumes a large amount of water resources. Wet cooling power generation technology has restricted the development of the power industry, and air cooling technology has emerged. Since air cooling has the characteristics of water saving, it is in line with my country's national conditions and national industrial policies, so it has won the market and shown good market prospects.

[0003] With the trend of large-scale units, indirect air cooling systems need to be equipped with larger heat exchange areas and higher towers. At present, the solution widely adopts increasing the height of the radiator to increase the heat exchange area, but at the same time, the corresponding tower air inlet height should be increased, which increases the design difficulty and construction cost of the tower support. At the same time, with the increase of the tower air inlet height and the decrease of the air inlet diameter, the resistance of the air turning upward in the tower increases sharply, resulting in a sharp increase in the resistance in the tower and reducing the utilization rate of the tower.

[0004] Therefore, it is necessary to study an indirect air cooling system with a large cooling triangle to address the shortcomings of the prior art and to solve or alleviate one or more of the above problems. [Contents of the utility model]

[0007] According to the above aspects and any possible implementation manner, there is further provided an implementation manner, wherein the first water inlet pipe is a cooling tube bundle water inlet pipe.

[0008] According to the above aspects and any possible implementation, there is further provided an implementation, wherein the second water inlet pipe is a cooling tube bundle water inlet mother pipe.
