Solution Overview
Problem
Current computer water cooling systems face challenges with large volume and thickness due to the integration of water pumps and water chambers, affecting aesthetics and overall design integrity, especially in transparent cases.
Innovation Solution
A non-contact driving structure is introduced with a water chamber and pump seat as independent chambers, utilizing an axial flux motor design where the stator and rotor are axially tangent, reducing overall thickness and volume while maintaining functionality and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the water pump and water chamber are integrated with the stator shell extending into the water chamber, then the brushless motor-driven impeller is achieved, but the water chamber volume is reduced and overall volume increases
Solution Approach 1:
The patent divides the water pump into a separate pump body that is independently mounted on the water chamber rather than being integrated into it. The stator shell is positioned on the pump body with the rotor extending into the pump body's inner cavity, creating distinct functional zones. This segmentation allows the water chamber to maintain its full volume while the motor components are housed in the separate pump assembly.
2Volume of stationary object
If the water pump and water chamber are separated into independent chambers, then the water chamber volume is maintained, but the overall integrity and aesthetics are poor
Solution Approach 1:
The patent merges the water pump and water chamber into a unified cooling assembly where the pump body is mounted on the water chamber's upper wall. The stator shell is fixedly provided with the rotor, and the impeller is arranged on the water chamber's top wall. This merging creates a compact integrated structure that maintains both functional integrity and aesthetic appearance while preserving the water chamber's volume.
3Ease of operation
If the stator shell extends into the water chamber to enable impeller-driven fluid flow, then the water cooling function is achieved, but the thickness and volume increase affecting aesthetics
Solution Approach 1:
The patent repositions the motor components from a radial arrangement where the stator shell would extend into the water chamber to an axial arrangement where the rotor and stator are stacked in the axial direction. The rotor is located below the stator with magnetic fields that are axially tangent, allowing the impeller to be driven through the top wall of the water chamber without increasing the radial thickness. This dimensional change reduces the overall thickness while maintaining the fluid flow function.
