Solution Overview
Problem
Conventional heat dissipation systems using vapor/liquid condensation face issues with liquid accumulation and insufficient driving force due to long or narrow condensation unit pipelines, leading to interrupted circulation and heat dissipation failure.
Innovation Solution
A vapor/liquid condensation system with a shorter pipeline path and lower resistance, featuring a condensation unit with a partitioned chamber and multiple vapor and liquid flow tubes, and an evaporation unit connected via conduits, allowing vapor-phase working fluid to flow and condense into liquid phase efficiently, reducing pipeline resistance and preventing circulation interruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the condensation unit uses a long pipeline path, then the vapor can flow sufficiently to the condensation unit, but the liquid accumulates in the pipeline and fails to flow back to the evaporation unit
Solution Approach 1:
The condensation unit is divided into multiple condensation chambers (first condensation chamber, second condensation chamber, etc.) connected in series, with each chamber having its own condensation pipeline. This segmentation shortens the pipeline path from the heat source to each condensation chamber while maintaining sufficient vapor flow path through the sequential chamber arrangement. The liquid returns to the evaporation unit through separate return pipelines from each chamber, preventing accumulation.
2Device complexity
If the condensation unit uses a narrow pipeline path, then the system structure is compact, but the driving force of the vapor is insufficient to drive the liquid to circulate
Solution Approach 1:
The system arranges multiple condensation chambers in a sequential spatial arrangement, extending the vapor flow path through multiple chambers while keeping individual pipeline segments short. This multi-dimensional spatial configuration allows sufficient vapor driving force to be distributed across multiple shorter pipeline sections, enabling liquid circulation without requiring excessively long or narrow single-path pipelines.
3Reliability
If the pipeline path is shortened and resistance is lowered, then liquid accumulation is prevented, but the vapor flow path may become insufficient
Solution Approach 1:
The condensation unit is divided into multiple condensation chambers (first condensation chamber, second condensation chamber, etc.) connected in series, with each chamber having its own condensation pipeline. This segmentation shortens the pipeline path from the heat source to each condensation chamber while maintaining sufficient vapor flow path through the sequential chamber arrangement. The liquid returns to the evaporation unit through separate return pipelines from each chamber, preventing accumulation.

AI summary
A vapor/liquid condensation system includes a condensation unit and an evaporation unit. The condensation unit is connected with the evaporation unit via conduits. The evaporation unit has a liquid inlet, a vapor outlet and an evaporation chamber in communication with each other. The evaporation unit converts liquid-phase working fluid into vapor-phase working fluid, which spreads to the condensation unit. The condensation unit cools and condenses the vapor-phase working fluid into liquid-phase working fluid, which goes back the evaporation unit. After the vapor-phase working fluid enters the condensation unit, the vapor-phase working fluid is distributed and condensed into liquid-phase working fluid. Then the liquid-phase working fluid is collected and then goes back to the evaporation unit. The length of the pipeline is shortened and the pipeline pressure is lowered to avoid interruption of heat dissipation circulation and failure in heat dissipation.
