Description

technical field [0001] The invention discloses a radiator, in particular to an air-cooled radiator arranged vertically and capable of switching between single and double processes. Background technique [0002] The indirect dry air cooling system consists of a natural draft cooling tower and a surface condenser. The circulating water after desalination undergoes two surface heat exchanges through the condenser and the air-cooled radiator, forming a closed cycle. This system has become the mainstream of power development in areas rich in coal and poor in water due to its advantages in water saving and environmental protection. [0003] After the circulating water absorbs heat in the condenser, it is cooled by the radiator at the bottom of the air cooling tower. The output of the unit is positively correlated with the cooling effect of the air-cooled radiator. The heat exchange efficiency of the single-flow condensation mode is poor. In order to improve the cooling capaci...

AI Technical Summary

Problems solved by technology

The output of the unit is positively correlated with the cooling effect of the air-cooled radiator. The heat exchange efficiency of the single-flow condensation mode is poor. In order to improve the cooling capacity of the air-cooling tower, aluminum radiators with high precision and good cooling effect are mostly used, and the double-flow arrangement is used. , but due to the thin heat sink and poor anti-freezing ability, the radiator is extremely vulnerable to freezing in winter, which not only reduces the cooling effect of the system, but also causes damage to the radiator

However, the repair process of radiators is complicated and the cycle is long. Once the local area is frozen, the accident will rapidly expand, causing the radiators to freeze, causing huge economic losses.

In the indirect air-cooled units that have been put into operation, the air-cooled radiators have been frozen, cracked and leaked. These accidents have affected the safety of the units, resulting in limited load output or unplanned shutdown of the units, and caused equipment damage worth tens of millions of yuan.
