A hybrid cooling tray for a battery pack, the tray having: a base defining a first end and a second end that are lengthwise spaced apart from each other and a first side and a second side that are widthwise spaced apart from each other, and wherein the base defines an inner surface and an outer surface; wherein the inner surface defines a coolant channel having an upstream end configured to receive a coolant flow and a downstream end configured to discharge the coolant flow, wherein the coolant channel defines a first transverse side and a second transverse side that extend between the upstream and downstream ends, and turbulators are disposed within the coolant channel between the upstream and downstream ends and define one or more of projections out of the base and impressions into the base, and wherein: at least two of the turbulators have a differing size, shape, pitch, yaw or roll orientation relative to each other; or a turbulator density per square unit area of the coolant channel differs from the upstream end to the downstream end of the coolant channel.
