Traction battery thermal plate manifold

A traction battery system comprising:

• a plurality of battery cells;
• a thermal plate having a heat exchange region, lateral sides defining two planes, and configured to support the cells and to direct fluid through the thermal plate;
• and
• an inlet manifold including an inlet and an outlet in fluid communication with the heat exchange region and having a cross-sectional area defining a third plane, and defining spaced apart extrusions arranged in a plurality of curved fountain-type patterns extending from the manifold inlet to the outlet to disperse fluid across the outlet,
• wherein the two planes and third plane define a region normal to the cross sectional area and wherein the inlet is positioned outside of the region.

• an inlet manifold including an inlet and an outlet in fluid communication with the heat exchange region and having a cross-sectional area defining a third plane, and fluid distribution channels defined by passageways spaced apart from one another and arranged in an arc-like pattern to continuously extend from the manifold inlet to the outlet to disperse fluid across the outlet,
• wherein the two planes and third plane define a region normal to the cross sectional area and wherein the inlet is positioned outside of the region.
