The invention provides an electronic assembly and electronic equipment. The electronic assembly comprises a circuit board assembly and a cold plate. The circuit board assembly comprises a single board, a first heating device and a second heating device, wherein the first heating device and the second heating device are arranged on the single board. The cold plate comprises a liquid inlet and a liquid outlet, and the cooling port flows into the cold plate from the liquid inlet and flows out of the cold plate from the liquid outlet. The cold plate comprises a first cooling area and a second cooling area, and the second cooling area is closer to the liquid outlet relative to the first cooling area. Cooling liquid firstly flows through the first cooling area from the liquid inlet and then flows to the second cooling area, and the heat dissipation capacity of the first cooling area is higher than that of the second cooling area. The heating density of the first heating device is higher than that of the second heating device, so that the first heating device is in heat-conducting connection with the first cooling area, and the second heating device is in heat-conducting connection with the second cooling area. The heat dissipation capacity of the cold plate is reasonably utilized, the heat dissipation effect of the first heating device and the second heating device is improved, and energy consumption can be reduced.

    本申请提供了一种电子组件及电子设备,该电子组件包括电路板组件和冷板。上述电路板组件包括单板、第一发热器件和第二发热器件,第一发热器件和第二发热器件设置于单板。上述冷板包括进液口和出液口,冷却口从进液口流入冷板,从出液口流出冷板。该冷板包括第一冷却区和第二冷却区,第二冷却区相对于第一冷却区更靠近出液口。冷却液从进液口先流经第一冷却区,再流至第二冷却区,第一冷却区的散热能力强于第二冷却区的散热能力。第一发热器件的发热密度高于第二发热器件的发热密度,使第一发热器件与第一冷却区导热连接,第二发热器件与第二冷却区导热连接。合理利用冷板的散热能力,提升第一发热器件和第二发热器件的散热效果,还可以节约能耗。
