Patent number: 11272641Abstract: Example embodiments described in this disclosure are generally directed to a mounting bracket for deployment in a vehicle. In one embodiment, a multilayer mounting bracket includes a first layer made of a dual-conductive polymer and a second layer made of a polymer that includes an endothermic blowing agent. The dual-conductive polymer includes carbon material that renders the first layer electrically conductive and also includes graphite material that renders the first layer thermally conductive. The endothermic blowing agent renders the second layer thermally insulative. An electronic module such as an engine controller can be mounted upon the first layer, which operates as a heat sink to dissipate heat generated by the electronic module and also operates as an electromagnetic interference (EMI) shield. The second layer prevents heat from being transferred from the first layer into another electronic module that may be mounted upon the mounting bracket.Type: GrantFiled: March 19, 2020Date of Patent: March 8, 2022Assignee: Ford Global Technologies, LLCInventors: Stuart C. Salter, Paul Kenneth Dellock, John Budaj, Estefania Rojas Silva, Marko Escalante
