ANTI-COUNTERFEIT LABEL AND ANTI-COUNTERFEIT LABEL VERIFICATION METHOD

An anti-counterfeit label, comprising: a first structural layer (100), a second structural layer (200), a positioning identifier (300), and sheet-like or dot-shaped optically identifiable anti-counterfeit elements (400) located between the first structural layer (100) and the second structural layer (200). The adhesive force of at least one of the anti-counterfeit elements (400) to the second structural layer (200) is greater than the adhesive force thereof to the first structural layer (100). When the first structural layer (100) is separated from the second structural layer (200), the at least one of the anti-counterfeit elements (400) is separated from the first structural layer (100), at least a portion of the positioning identifier (300) located on the surface of or inside the first structural layer (100) is separated from the at least one of the anti-counterfeit elements (400). One of the first structural layer (100) and the second structural layer (200) is a translucent protective ...

Battery pack cooling plate runner design method

The invention relates to a battery pack cooling plate runner design method. The design method comprises the following steps: S1, abstracting different composition units of the flow channel into different types of one-dimensional flow resistance blocks; 2, according to target parameters meeting the heat dissipation performance requirement and the overall size of the cooling plate, the one-dimensional flow resistance block is used for establishing an initial one-dimensional model of the flow channel; s3, on the basis of multiple times of one-dimensional simulation calculation, determining a final one-dimensional model meeting the target parameters by adjusting the initial one-dimensional model; and S4, establishing a three-dimensional model of the flow channel based on the final one-dimensional model. The design method aims at effectively meeting the heat dissipation performance requirement of the battery pack, and meanwhile, the research and development time and the economic cost are remarkably ...
