Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual assembly of heat pipes and vapor chambers often results in inconsistent and imprecise positioning, leading to damaged wick structures, reduced heat conduction efficiency, and disrupted fluid cycles due to inaccurate insertion depths and orientations.
Innovation Solution
A combined heat dissipation structure with positioning portions on the vapor chamber and heat pipe ensures accurate alignment and assembly, featuring engagement mechanisms to prevent improper insertion and enhance wick structure contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual assembly is used to combine heat pipe and vapor chamber, then assembly flexibility is maintained, but positioning precision and consistency deteriorate
Solution Approach 1:
The heat pipe is designed with a positioning structure that automatically engages with the vapor chamber during assembly. The positioning groove on the heat pipe fits with the positioning protrusion on the vapor chamber, enabling self-alignment and precise positioning without requiring manual adjustment or complex fixtures, thus maintaining assembly simplicity while achieving consistent positioning accuracy.
Solution Approach 2:
A positioning structure acts as an intermediary mechanism between the heat pipe and vapor chamber. The positioning groove and positioning protrusion form a mechanical interface that guides the heat pipe into the correct position relative to the vapor chamber, ensuring consistent positioning while simplifying the assembly process through automatic engagement.
2Reliability
If deep insertion is used to ensure heat pipe contact with vapor chamber, then heat conduction efficiency improves, but wick structure damage risk increases
Solution Approach 1:
The positioning groove is pre-formed at a specific depth on the heat pipe, and the positioning protrusion is pre-formed on the vapor chamber at the corresponding location. This preliminary positioning structure ensures that when assembly occurs, the heat pipe inserts to the exact required depth without requiring forceful or blind insertion, thereby ensuring adequate heat conduction contact while preventing damage to the wick structure through controlled, precise insertion depth.
3Reliability
If consistent positioning is achieved through precise manufacturing, then heat dissipation performance improves, but manufacturing complexity increases
Solution Approach 1:
The positioning groove and positioning protrusion form a self-aligning mechanism that automatically ensures consistent positioning during assembly. This design eliminates the need for complex positioning fixtures, specialized assembly tools, or manual adjustment procedures, achieving reliable heat dissipation performance through a simple geometric interlocking feature that is straightforward to manufacture.

AI summary
A combined heat dissipation structure includes a vapor chamber and at least one heat pipe. The vapor chamber includes an upper plate and a lower plate. A plate chamber is defined between the upper and lower plates. A first wick structure and a working fluid are provided in the plate chamber. The upper plate has at least one through hole communicating with the plate chamber and an annular flange protruding from the through hole toward the upper plate. The annular flange has a first positioning portion. The heat pipe has two ends defined as a closed end and an open end. A second positioning portion is formed on the heat pipe close to the open end. The second positioning portion is engaged with the first positioning portion, so that the heat pipe and the vapor chamber can be combined quickly, accurately.
