Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water-cooling heat dissipation modules have inefficiencies due to short distances between cold and hot water pipes, leading to impaired heat dissipation as the heated airflow from the hot-water pipe blows towards the cold-water pipe, increasing the cold-water pipe's temperature and reducing overall efficiency.
Innovation Solution
A water-cooling heat dissipation module design where an airflow from a fan sequentially blows over both the cold-water and hot-water pipes, optimizing their relative locations to enhance heat dissipation efficiency, including a hot-water container, cold-water container, fluid communication structure, and fan placement to prevent heat transfer between the airflow and cold-water pipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the distance between cold-water pipe and hot-water pipe is shortened, then the device compactness is improved, but the heat dissipation efficiency deteriorates due to thermal conduction and heated airflow blowing toward the cold-water pipe
Solution Approach 1:
The patent transitions from a one-dimensional linear arrangement to a two-dimensional planar layout, positioning hot-water and cold-water pipes in parallel rows separated by a substantial distance. This dimensional change allows both compactness and efficient heat dissipation to be achieved simultaneously by optimizing spatial arrangement in multiple directions.
Solution Approach 2:
The patent introduces air flow as an intermediary medium between the hot-water and cold-water pipes. The air flow carries heat away from the hot-water pipes and prevents it from transferring to the cold-water pipes, serving as a thermal buffer that maintains the temperature differential necessary for efficient heat dissipation while allowing compact pipe arrangement.
2Device complexity
If the relative locations of fan, hot-water pipe and cold-water pipe are not optimized, then the device structure is simplified, but the heat dissipation efficiency deteriorates as heated airflow blows toward the cold-water pipe
Solution Approach 1:
The patent applies local quality by creating distinct functional zones: a hot-water pipe region with specific airflow patterns, a cold-water pipe region with different airflow characteristics, and transition zones between them. Each region is optimized for its specific function, with the fan positioned to generate appropriate flow patterns in different locations rather than using a uniform structure throughout.
Solution Approach 2:
The patent employs dynamic air flow control to manage heat dissipation. The fan creates a dynamic airflow field that continuously moves heat-carrying air from the hot-water pipe region toward the cold-water pipe region, adapting the thermal management strategy to operational conditions rather than relying on static thermal conduction paths.

Function Achieved in This Case
This design enhances the overall heat dissipation efficiency by preventing unnecessary heat absorption and directing airflow to reduce the temperature of the hot-water pipes while avoiding heat transfer to the cold-water pipes, thereby improving cooling performance.

Implementation Method 3
the distance between a cold-water pipe and a hot-water pipe is very short. Moreover, due to the thermal conduction, the cold-water pipe may absorb the heat from the hot-water pipe

AI summary
A water-cooling heat dissipation module includes a hot-water heat exchange structure, a cold-water heat exchange structure, a fluid communication structure and a fan. The fluid communication structure is in communication with the hot-water heat exchange structure and the cold-water heat exchange structure. The fan and the hot-water heat exchange structure are opposed to each other with respect to the cold-water heat exchange structure. An airflow produced by the fan blows the cold-water heat exchange structure and the hot-water heat exchange structure sequentially. Consequently, the cold-water heat exchange structure will not receive the heat from the hot-water heat exchange structure through the airflow.
