Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional liquid cooling flow channels are used, then heat dissipation capability is provided, but temperature consistency across the width direction deteriorates due to significant variations in cooling effectiveness
Solution Approach 1:
The patent applies local quality by introducing a flow guide structure (comprising flow guide pillars and flow guide plates) at specific locations within the cooling channels. This structure locally modifies the flow characteristics to redistribute the liquid coolant, ensuring more uniform flow velocity and temperature distribution across the width direction of the channels, particularly addressing the inconsistent cooling effectiveness in conventional designs
2Productivity
If liquid cooling methods are employed to enhance heat dissipation, then computing power performance is improved, but flow velocity uniformity across the width direction deteriorates
Solution Approach 1:
The flow guide structure is strategically positioned within the cooling channels to locally adjust and redistribute the liquid flow. The flow guide pillars and plates create controlled flow paths that balance the velocity distribution across the channel width, maintaining high heat dissipation efficiency while eliminating flow velocity hotspots and cold spots
Solution Approach 2:
The flow guide structure acts as an intermediary element between the liquid coolant and the cooling channel walls. It mediates the flow distribution by redirecting the liquid to ensure more uniform contact with the channels across the width direction, thereby improving both flow velocity uniformity and overall heat dissipation efficiency
3Device complexity
If conventional flow channel designs are used, then device complexity is reduced, but structural strength and anti-noise capabilities deteriorate
Solution Approach 1:
The flow guide structure is divided into modular components including flow guide pillars and flow guide plates that can be independently positioned and adjusted within the cooling channels. This segmentation allows for optimized structural strength and anti-noise capabilities while maintaining relatively simple overall device complexity, as each component performs a specific flow control function

AI summary
Disclosed are a liquid-cooled flow channel plate and a supercomputing device. The liquid-cooled flow channel plate comprises a base plate and a cover plate. A plurality of sequentially communicated elongated slots that are juxtaposed are arranged in one surface of the base plate. A separating strip is formed between two adjacent elongated slots of the elongated slots. A free end of the separating strip is disposed at a junction between the two adjacent elongated slots. A flow guide structure is arranged at the junction, wherein the flow guide structure includes a flow guide pillar and a first flow guide plate. The flow guide pillar is disposed in an extension direction of the separating strip and is spaced apart from both the separating strip and a slot wall of the elongated slot where the flow guide pillar is disposed. The first flow guide plate is connected at least to one side of the flow guide pillar close to one of the elongated slots. A free end of the first flow guide plate extends towards the elongated slot on a side where the first flow guide plate is disposed. The cover plate is fitted onto the base plate and rests on the separating strip and the flow guide pillar, such that each of the elongated slots, together with a corresponding portion of the cover plate, forms a medium flow channel. According to the present disclosure, the uniformity of the flow velocity and temperature of a medium across a width direction of the flow channel is enhanced, and the structural strength and anti-noise capability of the liquid-cooled flow channel plate is improved.
