Two-Phase Cooling Device Housing for Ice Formation Control

The patent applies preliminary action by designing the bottom region with a lower part and upper part structure before freezing occurs. This pre-configured structure ensures that when the cooling medium freezes and expands, the ice formation progresses from the lower part upward, preventing enclosed liquid pockets and subsequent bulging. The design anticipates the freezing process and prepares the geometry to accommodate expansion safely.

The patent changes the geometric parameters of the bottom region by dividing it into a lower part and an upper part with specific volume ratios. This parameter modification alters the freezing dynamics, ensuring that the ice front moves upward rather than forming enclosed pockets. The volume ratio parameter (lower part volume vs. upper part volume) is optimized to prevent bulging while maintaining cooling performance.

The patent prevents pressure buildup by preliminarily designing the bottom region geometry to allow controlled ice formation. The lower part and upper part structure ensures that freezing progresses upward, maintaining an open pathway for liquid cooling medium and preventing enclosed high-pressure pockets before they can form and damage the housing.

The patent applies local quality by creating different geometric characteristics in different regions of the bottom region. The lower part has a larger volume to accommodate initial ice formation and liquid cooling medium, while the upper part has a smaller volume. This local differentiation ensures that pressure is distributed and managed locally rather than building up uniformly, preventing housing damage.
