A heat exchanger system includes a controller configured to direct a first power signal to a first cooling fan module to operate a first motor at a first rotational speed to provide a first flow rate that meets a first desired heat dissipation rate; directing a second power signal to a second cooling fan module to operate a second motor at a second rotational speed to provide a second flow rate that meets a second desired heat dissipation rate; a rotational speed difference between the first rotational speed and the second rotational speed is maintained such that an acoustic characteristic of at least one of the first heat exchanger assembly and the second heat exchanger assembly is below a predetermined acoustic characteristic threshold.

    一种热交换器系统,包括控制器,该控制器被配置用以将第一功率信号引导到第一冷却风扇模块,以在第一转速下操作第一马达,从而提供满足第一所需散热率的第一流速;将第二功率信号引导到第二冷却风扇模块,以在第二转速下操作第二马达,从而提供满足第二所需散热率的第二流速;同时维持所述第一转速和所述第二转速之间的转速差,使得第一热交换器组件和第二热交换器组件中的至少一个热交换器组件的声学特性低于预定声学特性阈值。
