Cooling plate, battery pack and electric equipment

The invention discloses a cooling plate, a battery pack and electric equipment. The cooling plate is provided with at least one flow channel, the flow channel comprises a first flow channel, the cross section of the first flow channel is in a non-circular shape, and after the cooling plate is subjected to external pressure, the cross section of the first flow channel changes from the non-circular shape to the circular shape. After the cooling plate is subjected to external pressure, the shape of the cross section of the first flow channel is changed from a non-circular shape to a nearly-circular shape, so that the volume of the first flow channel is increased, the total cooling liquid amount in the cooling plate cannot be reduced, and the cooling efficiency of the cooling plate is improved. 本发明公开了一种冷却板、电池包和用电设备。冷却板设有至少一个流道，所述流道包括第一流道，所述第一流道的截面形状呈非圆形，在所述冷却板受到外部压力作用后，所述第一流道的截面形状由非圆形向圆形变化。本发明实施方式的冷却板在受到外部压力作用后，第一流道的截面形状由非圆形向近圆形变化，使得第一流道的容积变大，从而冷却板内的总冷却液量不会降低，提高了冷却板的冷却效率。
