What should I do if the fan in the air cooler has poor heat dissipation?

1. Replace with a high-power air cooler cooling fan;
2. If air cooling is used for a long time and the radiator is not cleaned in a timely manner, remove the core and clean it with high-pressure water to restore the thermal conductivity of aluminum alloy;
3. If the air volume of the fan is low, replace it with a high air volume fan;
4. If the device space is limited and it is not suitable for large-sized standardized products, it is necessary to customize and optimize the structural dimensions. The same air-cooled machine has a working environment temperature, which is particularly important. Its impact on the oil temperature of the system is a crucial factor.
For example, if the winter ambient temperature is 10 ° C and the oil temperature is 45 ° C, then the autumn ambient temperature is 25 ° C and the oil temperature will reach 60 ° C. In summer, the ambient temperature is 35 ℃, and the oil temperature can reach 70 ℃. Generally speaking, a hydraulic oil temperature of 60 ℃ and a smooth oil temperature of 70 ℃ are fundamentally compliant with the requirements, except for special equipment. If the oil temperature is too low, restraining the increase in liquid power loss is not conducive to improving the efficiency of the entire working system. The heat dissipation surface and fan airflow are internal factors that affect the heat dissipation effect of the air cooler itself. The temperature of the working environment is an external factor and is influenced by seasonal changes.
So, when we calculate the heat dissipation of the air-cooled cooling fan, we calculate it based on the highest working environment. There is a safety margin of about 10%. The practical situation encountered by Helik is that due to customers' cost considerations or inaccurate parameters provided by relevant parties during the selection process, or neglecting the heating of local machine machinery and other electric components, the selection is too small, resulting in a larger practical temperature rise. This phenomenon can only be replaced with a larger one.
For professional reasons, let me repeat the question: whether air cooling, water cooling, or medium cooling (air conditioning) is suitable or not, there is no better question. Providing precise heating efficiency is the only way to select heat dissipation.
