风冷机组主要检查进出油温相差是否在10度左右，如果小于这个值则应检查散热器表面翅片是否脏堵，如果脏堵可用洁净空气将散热器表面粉尘，并检查散热器翅片是否腐蚀，
The air-cooled unit mainly checks whether the difference in inlet and outlet oil temperature is about 10 degrees. If it is less than this value, check whether the fins on the radiator surface are dirty and blocked. If they are dirty and blocked, clean air can be used to dust the radiator surface and check whether the fins of the radiator are corroded,
腐蚀厉害的话则有需要考虑更换散热器总成，内部管道是否有脏堵现象，若有此现象则可用循环泵循环带务必酸性药水清洗，务必注意药水浓度，以及循环时间，避免散热器因药水腐蚀造成散热器穿腔。
If the corrosion is severe, it is necessary to consider replacing the radiator assembly and whether the internal pipeline is dirty and blocked. If this phenomenon occurs, the circulating belt of the circulating pump can be used. Be sure to clean with acidic liquid medicine. Be sure to pay attention to the concentration of liquid medicine and the circulation time to avoid the radiator penetrating the cavity of the radiator due to liquid medicine corrosion.
