Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water-cooling devices have poor heat dissipation for the stator assembly, leading to potential burnout and reduced operational efficiency due to air cooling, and the structural strength and waterproofing of the liquid reservoir are inadequate, resulting in excessive volume and inefficiency.
Innovation Solution
The stator is integrally embedded in the liquid reservoir main body via embedded injection molding, creating a solid enclosure that enhances structural strength, achieves waterproofing, and allows the stator to be protected from liquid contact, while the rotor and impeller are exposed to the cooling liquid to efficiently dissipate heat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stator assembly is disposed on the outer side of the water-cooling device to prevent contact with liquid, then the reliability of the stator is improved, but the thickness of the outer case increases leading to a gap between the rotor and stator that reduces pump operation efficiency
Solution Approach 1:
The patent merges the protective function previously performed by a separate outer case with the liquid reservoir main body itself. The liquid reservoir main body is designed to directly enclose and protect the stator assembly, eliminating the need for a separate thick outer case. This integration maintains stator protection while reducing the gap between rotor and stator, thereby improving pump operation efficiency.
2Strength
If the outer case thickness is increased to ensure structural strength, then the strength of the water-cooling device is improved, but the total volume of the device becomes excessively large
Solution Approach 1:
The protective and structural functions are merged into the liquid reservoir main body, which is designed with sufficient thickness to provide both structural strength and stator protection. This eliminates the need for an additional thick outer case, thereby reducing the total volume of the water-cooling device while maintaining required strength.
Solution Approach 2:
The liquid reservoir main body is designed to perform multiple functions simultaneously: it contains the cooling liquid, provides structural strength, and protects the stator assembly. This multi-functionality eliminates the need for separate protective outer cases, reducing overall device volume while maintaining all required functions.
3Reliability
If the stator assembly is isolated from the cooling liquid by air cooling, then the reliability of the stator is improved, but the heat dissipation effect becomes poor causing heat accumulation and potential burnout
Solution Approach 1:
The patent introduces thermal conduction as an intermediary mechanism between the stator and cooling liquid. The liquid reservoir main body acts as a thermal conductor, transferring heat from the stator to the cooling liquid without requiring direct contact between the stator and liquid. This mediator approach enables effective heat dissipation while maintaining stator protection.
4Reliability
If multiple separate components are used to achieve stator protection and heat dissipation, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (stator protection, heat dissipation, and structural support) into a single integrated liquid reservoir main body design. The liquid reservoir main body directly encloses the stator assembly and utilizes thermal conduction to dissipate heat, eliminating the need for separate protective outer cases and complex heat dissipation structures, thereby reducing device complexity.
