Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems face inefficiencies due to bubble merging, which prevents small bubbles from entering corners and gaps, hindering heat dissipation and cooling efficiency.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If bubbles are generated through boiling of liquid, then heat dissipation is enhanced through latent heat, but bubbles merge to create bigger bubbles that cannot enter corners and gaps
Solution Approach 1:
The patent changes the size parameter of bubbles from large (boiling-generated) to extremely small (50-1000 nm) through nanobubble generation technology. This parameter change enables bubbles to penetrate corners and gaps that were previously inaccessible, resolving the contradiction between heat dissipation efficiency and bubble penetration capability
Solution Approach 2:
The patent employs short-lived nanobubbles that rapidly dissolve or collapse after delivering their cooling function. These transient nanobubbles can access tight spaces and then disappear, leaving no persistent blockage, thus maintaining both high heat dissipation efficiency and excellent penetration capability
2Device complexity
If large bubbles are generated, then heat exchange occurs through phase transition, but liquid flow is hindered and corners cannot be reached
Solution Approach 1:
The patent transforms the bubble size parameter to the nanoscale range (50-1000 nm), fundamentally changing the flow characteristics. Nanobubbles behave differently from large bubbles, exhibiting reduced buoyancy and enhanced ability to follow liquid flow into corners and gaps, thus improving liquid flow efficiency while maintaining cooling effectiveness
Solution Approach 2:
The patent segments the bubble population into extremely fine nanobubbles rather than using a few large bubbles. This segmentation creates numerous small units that can individually navigate complex flow paths and access narrow spaces, improving both flow efficiency and cooling coverage
3Loss of energy
If boiling mechanism is used to generate bubbles, then latent heat is utilized for cooling, but bubble size cannot be controlled and merging occurs
Solution Approach 1:
The patent replaces the thermal boiling mechanism with a mechanical/electrical nanobubble generation mechanism (such as ultrasonic vibration or electrochemical methods). This substitution provides precise control over bubble size at the nanoscale while eliminating the uncontrolled merging characteristic of boiling-generated bubbles, achieving both latent heat utilization and precise size control

AI summary
A liquid cooling system having a liquid cooling block coordinating with a bubble cooling liquid includes: a liquid cooling block having a channel, a liquid inlet, a liquid outlet and an adhesive surface; a bubble liquid source having a driving function for driving a liquid, connected to the liquid inlet by an incoming liquid pipe and adapted to provide a bubble cooling liquid; and a liquid storage tank connected to the liquid outlet by an outgoing liquid pipe, adapted to store the bubble cooling liquid, and connected to the bubble liquid source by a communication pipe. The size of the bubbles introduced by the bubble liquid source into the liquid ranges from 50 to 1000 nm. The bubble cooling liquid is a known material that does not boil in a normal working state and thus does not generate additional bubbles otherwise typical of boiling.
