[0002] Mining machine drives are one of the key components in modern mining equipment, and their performance directly affects the efficiency and safety of the entire mining operation. In order to ensure the quality and reliability of mining machine drives, strict aging tests need to be conducted during production. Traditional aging test methods usually use air cooling methods, which are simple and easy to implement, but have poor heat dissipation effect in high temperature environments, which can easily cause the mining machine drive to overheat and be damaged. In recent years, with the advancement of technology, water cooling systems have gradually become an important means of efficient heat dissipation, especially in high-load long-time running conditions, the stability and effectiveness of water cooling systems are more significant.

[0003] Currently, the common means for aging test of mining machine drives mainly include air natural cooling, air cooling and simple water cooling device. Air natural cooling mainly relies on environmental temperature to achieve cooling, which is suitable for light load or short time working conditions; air cooling removes heat through a fan, which is suitable for cooling needs under medium load; and the existing simple water cooling device adopts a single water pump and a single cooling path design, which can provide relatively stable cooling effect, but there are still some limitations for long-term reliable operation of mining machine drives.
