Liquid-Cooling Cold Plate Pipe Positioning Fixing Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid-cooling cold plates for electronic components face instability in cooling performance due to misalignment and deformation of metal pipes during the casting process, caused by stream pressure and flowing direction of molten metal.
Innovation Solution
The method involves embedding a metal pipe within a casting mold and using fixing brackets or protrusions to maintain positional accuracy, ensuring the metal pipe is accurately positioned relative to the heating components, and then casting the molten metal around it to form a stable cold plate structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a metal pipe is embedded in a casting mold without fixing brackets, then the casting process is simple, but the metal pipe deforms and misaligns due to stream pressure of molten metal
Solution Approach 1:
The metal pipe is positioned and fixed with fixing brackets before the casting process begins. The fixing brackets are attached to the metal pipe at multiple points, and positioning structures (protrusions and recesses) are pre-formed to ensure accurate positioning. This preliminary positioning action prevents deformation and misalignment during the subsequent casting process when molten metal flows into the mold.
2Manufacturing precision
If fixing brackets are attached to the metal pipe during casting, then positioning accuracy is maintained, but the manufacturing process becomes more complex
Solution Approach 1:
The fixing brackets are integrated with the cold plate main body through casting, merging two components (fixing brackets and cold plate) into a single integrated structure. The positioning structures (protrusions and recesses) are also formed as integrated features during the casting process. This merging approach maintains positioning accuracy while simplifying the overall structure and reducing the number of separate parts.
3Productivity
If the metal pipe is allowed to move freely during casting, then the casting process is fast and simple, but the cooling properties become unstable
Solution Approach 1:
The metal pipe is pre-positioned and secured with fixing brackets before casting begins, ensuring it cannot move or deform during the molten metal flow. The positioning structures are pre-formed to achieve the desired positioning accuracy. This preliminary fixation maintains cooling performance stability while allowing the casting process to proceed efficiently without requiring slow, controlled pouring.

AI summary
In a method of manufacturing a liquid-cooling cold plate, cast molding is performed after embedding a metal pipe for supplying a cooling liquid inside a casting mold. Fixing brackets to be attached to the metal pipe is provided to maintain a positional relationship between a plurality of portions of the metal pipe embedded in the casting mold. The casting molding is performed by pouring molten metal into the casting mold while the fixing metal parts are attached to the metal pipe.
