The invention provides a driving control module and a vehicle-mounted air conditioner. The driving control module comprises a circuit substrate and a multi-path voltage-multiplying boosted circuit, acopper-clad layer is laid on the circuit substrate, the voltage-multiplying boosted circuit is arranged on the circuit substrate, the voltage-multiplying boosted circuit is suitable for driving a plurality of loads to operate according to power supply signals, the voltage-multiplying boosted circuit comprises a plurality of power switch tubes which are arranged in parallel, and the plurality of power switch tubes are arranged side by side along a specified direction of the circuit substrate; the driving control module also comprises a driving chip which is suitable for inputting switch drivingsignals to the power switch tubes, the driving chip is arranged on one side of the power switch tubes arranged side by side, driving pins of the driving chip are arranged close to controlled pins ofthe power switch tubes, and the driving control module also comprises a heat radiator which is suitable for being electrically connected with the copper-clad layer so as to define a shielding area between the heat radiator and the copper-clad layer. According to the technical scheme, the shielding area formed between the heat radiator and a ground wire can shield electromagnetic interference emitted by the power switch tubes, and then the EMC effect is improved.

    本发明提供了一种驱动控制模块和车载空调器,其中,驱动控制模块包括:电路基板与多路的倍压升压电路,电路基板铺设有敷铜层,倍压升压电路设置于电路基板上,倍压升压电路适于根据供电信号驱动多个负载运行,倍压升压电路包括:并列设置的多个功率开关管,多个功率开关管沿电路基板的指定方向并排设置;驱动芯片,适于向功率开关管输入开关驱动信号,驱动芯片设置于并排的多个功率开关管的一侧,并且驱动芯片的驱动引脚靠近每个功率开关管的受控引脚布设,散热器,适于与敷铜层电连接,以在散热器与敷铜层之间限定出屏蔽区。通过本发明的技术方案,在散热器与地线之间形成的屏蔽区能够对功率开关管发出的电磁干扰进行屏蔽,进而改善EMC效果。
