Publication number: 20250096357Abstract: The present disclosure describes a multi-function, integrated Super Beam assembly structure with integrated structural, cooling, and transverse elastic compliance functions; and Thermal Management Propagation (TMP) protection. The Super Beam assembly includes a pair of parallel face plates, coolant channel cover plates, and coolant channels that are defined by the face plate and the one or more coolant channel cover plates. The structural design of the cooling channels, and the corresponding air gaps formed in-between them, allows a transverse elastic compliance of the Super Beam assembly to be tuned to different amounts of elasticity. Top, bottom and/or end structural channels may be included. A pair of TMP suppression channels may be attached to the Super Beam assembly structure with an adhesive “thermal fuse” that preferentially melts and causes the pair of TMP suppression channels to detach from the Super Beam assembly during overheating in a TMP event.Type: ApplicationFiled: November 1, 2023Publication date: March 20, 2025Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Lu Huang, Hui-ping Wang, Chengwu Duan, Derek F.
