Application: Combined thermal management and fire mitigation for large scale battery packages (Patent ID: US20230387502A1)

The patent filed by RTX Corp describes a battery system for aircraft that includes battery packages with multiple cells and a thermal management system connected to these packages. The system uses a flow of coolant to dissipate thermal energy from the battery packages through a phase change process. The method involves conducting thermal energy from the battery cells through an inter-cell separator to the coolant flow, causing a phase change that cools the cells, and then dissipating the thermal energy from the coolant.

The claims detail the specific components and configurations of the battery system, such as the use of a condenser heat exchanger to condense the coolant, a thermally conductive inter-cell separator between battery cells, and suppressant nozzles for emitting coolant into the battery cells. The method also includes variations in the phase change temperature range, types of coolant used, and materials for the inter-cell separator. Overall, the patent focuses on an innovative approach to managing thermal energy in battery systems, particularly for aircraft applications, through efficient cooling mechanisms and thermal energy transfer processes.
