In the hydropower engineering, the steel-covered air cushion pressure regulating chamber is widely used due to the outstanding advantages. The steel plate structure of the hydraulic power station is not only required to maintain the stability of the air cushion, but also required to bear complex working conditions such as water flow, gas pressure and temperature change, and is critical to the safe operation of the hydraulic power station.
In practice, steel sheets face a number of challenges. The water flow passes through the pressure regulating chamber at high speed, generates heat by friction with the inner wall of the steel plate, so that the temperature of the steel plate is quickly increased, and the temperature caused by compression and expansion of gas in the air cushion is greatly fluctuated, so that the steel plate can be influenced by heat conduction. For example, when the power generation power of a large hydropower station is adjusted, the gas pressure and the temperature in the pressure regulating chamber can change by tens of degrees celsius.

The deformation stress generated by expansion with heat and contraction with cold is easy to cause local deformation and even cracking of the steel plate, threatens the structural safety, reduces the mechanical property of the steel plate at high temperature, shortens the service life, and simultaneously, the temperature change causes unstable gas state in the air cushion to influence the accuracy and the high efficiency of pressure regulation of the pressure regulating chamber.
At present, although some conventional cooling measures are adopted, the effect is poor. The steel plate cooling device for the steel hood type air cushion pressure regulating chamber solves the technical problems of difficulty in coping with complex working conditions due to low heat dissipation efficiency, easiness in occurrence of heat dissipation dead angles due to the fact that external air cooling is limited by the pressure regulating chamber structure and the environment, incapability of fully exerting water cooling advantages due to the fact that the existing water cooling pipeline arrangement mode is uneven in water flow distribution, low in heat exchange efficiency and the like.
