在这项研究中，我们定量地讨论了几种热阻上升到表面的汽车硅基车载逆变器具有极高的热流密度为500 W/cm2。实践证明，采用无散热片的堆砌结构和采用两相浸没冷却技术的直接冷却方法作为关键技术是突破口。进一步验证了利用莲藕铜连接在槽形传热表面上自发产生的“呼吸现象”的两相浸没冷却技术，既能实现上述堆积结构，又能在饱和池沸腾环境（534 W/cm2）下实现超过500 W/cm2的极高临界热流密度
In this study, we quantitatively discuss several kinds of thermal resistances that rise up to the surface in thermal management of automotive SiC-based on-board inverters with extremely high heat flux of 500 W/cm2. It is proven that a stacking structure without a heat spreader and a direct cooling method utilizing two-phase immersion cooling technique can provide a breakthrough as the key technology. Furthermore, it is verified that a two-phase immersion cooling technique using “breathing phenomenon” spontaneously induced by a lotus copper jointed onto a grooved heat transfer surface can realize both the above-mentioned stacking structure and extremely high critical heat flux beyond 500 W/cm2 in a saturated pool boiling environment (534 W/cm2 at the
