Abstract: An assembly to reduce droplet accumulation and impingement on a lens assembly is disclosed. The assembly includes a camera body; a camera lens mounted within the camera body; and a groove surrounding the camera body. The groove has a first portion defined by a first sidewall, a second sidewall, and a first floor portion and a second portion defined by the first sidewall, a third sidewall, and a second floor portion. The first portion has a first width and a second portion has a second width larger than the first width.

Abstract: A battery module having a cooling plate assembly made from two non-contiguous cooling plates is provided. Each cooling plate has a side panel contiguous with a base panel, and the cooling plates are disposed opposite one another such that the base panels are coplanar and separated by a gap. An inlet duct runs along an upper edge of each side panel, and a manifold having coolant channels in fluid communication with the inlet duct is located in each side panel. The base panels have an outlet duct in fluid communication with the manifold. The cooling plate is designed to decrease friction loss as coolant flows through the inlet duct, manifold and outlet cut, and coolant channels in the manifold are designed to maintain a uniform flow rate across the manifold. Individual cells are disposed in the assembly such that the cell sides and bottoms are in heat-transfer contact with the plate side and base panels, respectively. The design of the battery module reduces operational temperature variation in the cells across the battery module and within each battery cell. Methods for reducing coolant flow friction loss, for establishing a more uniform coolant flow rate, and for reducing temperature variation are also provided.

Abstract translation: 提供具有由两个不连续冷却板制成的冷却板组件的电池模块。 每个冷却板具有与基板相邻的侧板，并且冷却板彼此相对设置，使得基板是共面的并且由间隙分开。 入口管道沿着每个侧板的上边缘延伸，并且具有与入口管道流体连通的冷却剂通道的歧管位于每个侧板中。 底板具有与歧管流体连通的出口管道。 冷却板被设计成当冷却剂流过入口管道，歧管和出口切口时减小摩擦损失，并且歧管中的冷却剂通道被设计成在歧管上保持均匀的流速。 单独的电池被设置在组件中，使得电池侧和底部分别与板侧和底板热传递接触。 电池模块的设计降低了电池模块和每个电池单元内的电池的工作温度变化。 还提供了减少冷却剂流动摩擦损失的方法，用于建立更均匀的冷却剂流动速率和降低温度变化的方法。
