Fiber-Embedded Vapor Chamber Steam Flow Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vapor chamber structures face challenges in providing sufficient space for steam flow due to the presence of supporting structures, which restricts the efficient transfer of thermal energy through phase changes.
Innovation Solution
A fiber-embedded vapor chamber structure is designed where fibers are disposed below a part of the supporters, and a space is reserved between the supporters to allow steam to flow, ensuring a sufficient steam space while maintaining the fiber's heat transfer function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If supporting structures are distributed in the vapor chamber to maintain space, then structural stability is improved, but the space for steam flow is reduced
Solution Approach 1:
The fiber layer is positioned at the bottom of the recessed zone, utilizing the vertical dimension to provide support while preserving horizontal steam flow pathways. This dimensional arrangement allows the supporting structure to occupy minimal space in the steam flow path while maintaining structural integrity.
Solution Approach 2:
The fiber layer is selectively disposed only at the bottom of the recessed zone rather than throughout the entire vapor chamber, providing localized support where needed while leaving the majority of the chamber volume available for steam flow. This localized approach maintains structural stability only where necessary.
2Power
If fibers are arranged between supporting structures to enhance heat conduction, then thermal energy exchanging efficiency is improved, but the steam flowing space is further reduced
Solution Approach 1:
The fiber layer is positioned in the vertical dimension at the bottom of the recessed zone rather than being distributed in the horizontal plane between supporting structures. This dimensional placement allows fibers to provide thermal conduction pathways without obstructing the horizontal steam flow channels.
Solution Approach 2:
Fibers are concentrated in the fiber layer at the bottom of the recessed zone rather than being dispersed throughout the entire chamber volume. This localized fiber arrangement provides sufficient thermal conduction at the heat source interface while preserving maximum steam flow space in the upper chamber regions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The structure effectively enhances steam flow and maintains the thermal energy transfer efficiency by reserving sufficient space between the supporters, thereby improving the overall heat dissipation performance.
Implementation Method 1
the vaporized working fluid is not provided with a sufficient steam flowing space to perform the heat conduction through phase changes
Implementation Method 2
a capillary structure formed by sintered powders and a metal woven net is provided
Implementation Method 3
the thermal energy may be cooled by being rapidly transferred and diffused to a plate surface having a large area

AI summary
A fiber-embedded vapor chamber structure includes: a lower plate having has a sealing edge surrounding a periphery of thereof and a recessed zone surrounded by the sealing edge and disposed on an inner surface of the lower plate; an upper plate having has an upper capillary layer disposed on a surface of the upper plate corresponding the lower plate; supporters are disposed in the recessed zone and extended toward the lower plate and the upper plate to abut against the lower capillary layer and the upper capillary layer. At least one strip-shaped fiber layer is disposed in the recessed zone. The fiber layer is flatly attached on the lower capillary layer or the upper capillary layer and pressed by a part of the supporters. As such, a space between the supports in the recessed zone is reserved to make steam flow.
