Water-Cooling Heat Dissipation Device with Segmented Radiator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water-cooling heat dissipation devices experience suboptimal heat exchange performance due to temperature rise in water flowing between multiple blocks, leading to inefficient heat dissipation across series-connected blocks and the phenomenon of cold and hot water mixing, which affects overall performance.
Innovation Solution
Incorporating multiple built-in water pumps within the water-cooling radiator to independently pump cold water to respective blocks for heat exchange, ensuring hot water is cooled by radiating fins before returning to the radiator, maintaining optimal temperature for effective heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple water-cooling blocks are connected in series to dissipate heat for multiple locations, then the heat dissipation coverage is improved, but the heat exchange effect deteriorates due to water temperature rise
Solution Approach 1:
The water outlet reservoir is divided into multiple independent water outlet chambers (first water outlet chamber, second water outlet chamber) by partitions. Each chamber is independently connected to a corresponding water-cooling block through dedicated radiating pipe units, creating separate water circulation pathways that prevent temperature cross-contamination between blocks.
2Adaptability or versatility
If water flows through multiple water-cooling blocks in sequence, then heat dissipation for multiple components is achieved, but heat exchange efficiency deteriorates due to cold and hot water mixing
Solution Approach 1:
The radiating pipe unit is segmented into independent radiating pipe units (first radiating pipe unit, second radiating pipe unit), with each unit exclusively serving a specific water-cooling block. This segmentation ensures that cold water from the radiator does not mix with hot water from different blocks, maintaining optimal heat exchange efficiency for each block.
Solution Approach 2:
Partitions act as intermediaries that physically separate different water circulation loops within the radiator. The first partition and second partition create distinct chambers that prevent direct mixing of water streams, ensuring that each water-cooling block receives consistently cold water for efficient heat exchange.

Function Achieved in This Case
This configuration enhances the heat exchange effect of each water-cooling block, improving the overall heat dissipation performance by maintaining cold water flow and efficient heat transfer through the radiator.
Implementation Method 1
hot water flows back to the first water inlet chamber and flows into the first radiating pipe unit to be cooled by the radiating fins
Implementation Method 2
The first water pump is configured to pump cold water in the first water outlet chamber to a first water-cooling block

AI summary
A water-cooling heat dissipation device includes a water-cooling radiator. The water-cooling radiator includes a radiating pipe unit, a water outlet reservoir, and a water inlet reservoir. The water-cooling radiator is provided with a first water pump and a second water pump. Each water pump is configured to pump cold water in a corresponding water outlet chamber to a corresponding water-cooling block to exchange heat and become hot water, hot water flows back to a corresponding water inlet chamber and flows into the corresponding radiating pipe unit to be cooled by radiating fins, and then cold water flows into the corresponding water outlet chamber.
