Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water-cooling heat dissipating modules require a large volume due to individual designs of the water pump and tank, and integrated designs face issues with fluid dissipation leading to reduced service life and limited application range, especially when used at multiple angles.
Innovation Solution
A compact heat dissipating module design that integrates the water pump and tank within a casing, utilizing a pressurizing device to maintain a full water level, ensuring efficient fluid suction and preventing pump failure when the module is flipped at multiple angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the water pump and water tank are integrated into one design to reduce installation space, then the volume of the heat dissipating module is reduced, but fluid dissipation through pipelines during long-term operation reduces service life
Solution Approach 1:
The patent integrates the water pump and water tank into a single unified structure where the water tank is formed by the cavity of the casing and the cover plate, eliminating the need for separate pipelines and connections. This merging reduces the overall volume while improving reliability by eliminating leak points at connections.
2Reliability
If the volume of the water tank is increased to prevent fluid dissipation and maintain water level, then service life is improved, but the volume of the product increases
Solution Approach 1:
The pressurizing device automatically maintains the water level in the tank by pressurizing the water when the level drops, causing water to flow back into the tank. This self-regulating mechanism ensures the water level remains sufficient for long-term operation without requiring a larger tank volume, as the system automatically compensates for fluid dissipation.
3Device complexity
If the heat dissipating module is designed for a single angle of application, then the structure is simplified, but the module cannot be used at multiple angles without pump failure
Solution Approach 1:
The patent positions the water inlet at a lower height than the stop valve, creating a gravity-assisted flow path that ensures water can always flow into the pump regardless of the module's orientation. This equipotential design allows the pump to efficiently suction fluid at multiple angles without failing, as the water level remains above the inlet due to the pressure differential and gravity.
4Ease of manufacture
If individual designs of water pump and water tank are used with hoses or metal pipes for connection, then ease of assembly is improved, but the space required increases
Solution Approach 1:
The patent integrates the water pump and water tank into a single unified structure where the water tank is formed by the cavity of the casing and the cover plate, eliminating the need for separate pipelines and connections. This merging reduces the overall volume while improving reliability by eliminating leak points at connections.
