风机组电机对冷却系统散热性能的影响分析

Analysis on effect of fan motor on the heat dissipation performance of cooling system

利用冷却系统散热性能匹配计算方法,分析了冷却系统散热性能与电机负荷特性、风机通风性能、风机效率的关系,得出配装同一功率等级不同电机的风机组对散热性能影响很小的结论,实际配套计算中,若条件不具备,可忽略这种影响。为冷却系统设计及相关运用人员提供了可靠且实用的参考。

By using the matching calculation method of heat dissipation performance for cooling system,we analyzed the relationship between cooling system heat dissipation performance and motor load characteristics,motor ventilation performance and fan efficiency.It was concluded that the fan unit equipped with the same power level and different motors has little effect on heat dissipation performance.In actual matching calculations,if conditions are not achieved,this effect can be ignored.This provides reliable and practical reference for cooling system design and related applications.
