Abstract: A cooling system includes a plurality of heat exchanger assemblies corresponding to a plurality of battery packs and a fluid conveyance assembly. Each heat exchanger assembly includes a first heat exchanger inlet-outlet and a second heat exchanger inlet-outlet configured to receive a heat transfer fluid or discharge the heat transfer fluid. The fluid conveyance assembly is coupled to the heat exchanger assemblies and configured to circulate the heat transfer fluid in parallel to the heat exchanger assemblies in a U-flow scheme with an inlet and an outlet of the heat transfer fluid arranged at the same location. The fluid conveyance assembly includes a plurality of flow restrictors configured to balance the heat transfer fluid flowing into the heat exchanger assemblies. The heat transfer fluid flows through the corresponding flow restrictor before flowing into the corresponding heat exchanger assembly of the battery pack.

Abstract: The present application provides a method for tracking and shooting a moving target and a tracking device, firstly, feature points of a template image corresponding to each shooting angle is extracted in advance, after that, only a feature point of a currently shot target image needs to be calculated when matching, and then the feature points of the target image is matched with the feature points of the template image corresponding to each shooting angle, the shooting angel corresponding to the matched template image is determined as the shooting angle of the currently shot target image; if the shooting angel of the currently shot target image does not coincide with the preset shooting angle of the target, the tracking device is moved to track and shoot the target, so that the shooting angel of the target coincides with the preset shooting angle of the target, greatly reducing the calculation amount of the detection and matching of the feature point and improving the real-time performance of the tracking and
