摘　　要：针对模具冷却系统的主要结构,分析了系统介质压降的基本构成,并对常用冷却系统介质压降进行了理论分析,给出了直管型、喷管型、折流板型和螺旋型冷却系统通道长度、转角与压降的关系,为冷却介质供给系统设计或模温机介质流量与扬程的确定提供了计算依据。The basic composition of medium pressure drop in main mould cooling system structure was analyzed. Theoretical analysis was made on the pressure drop in common cooling systems in which the relationship among the cooling channel length, comer and pressure drop of types of straight-pipe, bubbler-pipe, baffle and spiral cooling system was obtained. This can provide calculation basis for designing cooling medium supply system and determining the flow and lift of mould temperature controller.
