This invention discloses a battery pack structure, relating to the field of battery pack heat dissipation technology. It includes a lower temperature equalization unit and an upper dual-mode heat dissipation unit. The lower temperature equalization unit includes a housing containing battery cells filled with an insulating and thermally conductive immersion liquid, ensuring complete immersion of the cells for uniform temperature distribution. The upper dual-mode heat dissipation unit includes a dual-cavity heat dissipation aluminum cover sealed to the top of the housing. Its lower side is attached to the battery cell terminals and aluminum foil via an insulating and thermally conductive elastic pad, dissipating the most concentrated heat from the top via the shortest path. The dual-cavity heat dissipation aluminum cover integrates a liquid cooling channel and an air cooling channel located above it. This invention, through a thermodynamically optimized design of "bottom full immersion temperature equalization + top directional heat conduction," completely eliminates the temperature difference between the top and bottom of the battery cells. Combined with dual-mode switching of air cooling priority and liquid cooling backup, it significantly improves heat dissipation efficiency, battery cell temperature uniformity, safety, cycle life, and reduces energy consumption.

This invention discloses a combined power cycle system and method for cooling incoming air using ammonia-water, relating to the aerospace field. The system can switch between turbine-ramjet operating modes through an adjustable structure. Particularly during turbine-ramjet switching, ammonia-water is used to cool the high-temperature incoming air in the intake duct. The absorbed ammonia-water is then distilled to separate high-temperature ammonia gas and water. This invention combines heat exchanger precooling and jet precooling, effectively increasing the pressure ratio of the fan and compressor through multiple air cooling processes. This improves the compressor outlet gas temperature, thereby reducing compressor power consumption and providing greater thrust. Ammonia, as a supplementary fuel, has a higher specific impulse, addressing the thrust gap during engine mode transitions and effectively widening the operating speed range of the turbine engine.
