Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate cooling cabinets are used for air cooling and water cooling, then cooling reliability is improved, but device complexity and space occupation increase
Solution Approach 1:
The patent combines air cooling and water cooling systems into a single integrated cabinet structure. The air cooling device and water cooling device share the same cabinet space, with the water cooling loop constructed within the cabinet body to divide and organize electronic components. This merging approach maintains the reliability of dual cooling methods while reducing device complexity and space occupation compared to separate cooling cabinets.
2Reliability
If multiple separate cooling cabinets are used, then cooling capacity is improved, but the space occupied by the MRI system increases
Solution Approach 1:
The patent integrates both air cooling and water cooling systems within a single cabinet, eliminating the need for multiple separate cooling cabinets. The water cooling loop is constructed inside the cabinet body, and the air cooling device is arranged along the central axis of the water cooling device, creating a compact dual-cooling configuration that reduces the overall volume of the MRI system while maintaining adequate cooling capacity.
Solution Approach 2:
The water cooling loop is nested within the cabinet body structure, with pipes and channels integrated into the cabinet walls and partitions. The air cooling device is positioned along the central axis, utilizing the vertical space efficiently. This nesting approach allows both cooling systems to coexist in a compact arrangement, minimizing the space occupied by the MRI system.
3Volume of stationary object
If electronic components are densely arranged, then space efficiency is improved, but temperature distribution becomes uneven
Solution Approach 1:
The water cooling loop divides the cabinet body into a first cabinet space and a second cabinet space, with electronic components arranged in both spaces. This segmentation allows different cooling strategies to be applied to different regions, with the water cooling loop providing targeted cooling to high-heat components while the air cooling device provides general ambient cooling, thereby managing temperature distribution effectively despite dense component arrangement.
Solution Approach 2:
The patent implements local quality by providing different cooling mechanisms for different regions: water cooling through the loop for specific high-heat electronic components and air cooling through the fan for general ambient temperature control. This localized approach to cooling allows dense component arrangement while maintaining acceptable temperature distribution across different areas of the cabinet.

Implementation Method 3
after at least the first air flow flows through the first cabinet space and/or the second air flow flows through the second cabinet space, they are guided into the water cooling loop for heat exchange under the suction action of the fan on a second side
Implementation Method 4

AI summary
MRI system cabinet having a cabinet body with electronics and a water cooler with a water cooling loop. The water cooling loop divides the cabinet body into first and second cabinet spaces, and the electronics are along the first and second cabinet spaces. An air cooler is along the central axis of the water cooler and has a fan. A cooling cycle is formed where, on a first side, the fan generates a first air flow, which is sent to the first cabinet space through a first air path, and a second air flow, which is sent to the second cabinet space through a second air path. After flowing through the first and second cabinet spaces, the first and second air flows are guided into the water cooling loop for heat exchange under the suction action of the fan on a second side, and then directed into the air cooler.
