Heat Pipe Fixing Structure With Segmented Pressing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fixing structures for heat dissipation elements often damage the heat pipes during connection and require additional steps and materials, leading to increased manufacturing costs and environmental pollution.
Innovation Solution
A fixing structure that includes a base plate with a receiving recess and a fixing member with an extended portion that is inserted into clearances between the recess and the heat transfer element, allowing for a tight fit without damage and reducing the need for additional materials and steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If tight fitting is used to connect the heat pipe to the receiving recess, then the connection strength is improved, but the heat pipe is damaged or difficult to connect
Solution Approach 1:
The fixing member is divided into a pressing portion and an extended portion, with the extended portion further segmented into multiple pressing sections that can independently apply pressure to different locations of the heat pipe, enabling precise localized fixing without damage
Solution Approach 2:
The fixing member acts as an intermediary component between the receiving recess and the heat pipe, providing a mechanical pressing force that secures the heat pipe without requiring tight fitting that would cause damage
2Ease of operation
If loose fitting is used to connect the heat pipe to the receiving recess, then the ease of connection is improved, but additional glue or solder is needed
Solution Approach 1:
The fixing member provides self-service by automatically securing the heat pipe through its extended portion that presses against the heat pipe when installed, eliminating the need for additional glue or soldering steps
Solution Approach 2:
The pressing function is extracted from the receiving recess structure and implemented through a separate fixing member, allowing the receiving recess to maintain a simple loose fitting design while the fixing member provides the necessary securing force
3Strength
If glue or solder is used to bond the heat pipe to the receiving recess, then the connection strength is improved, but the production process is lengthened and manufacturing cost increases
Solution Approach 1:
The chemical bonding methods (glue or solder) are replaced with a purely mechanical pressing system using the fixing member, which secures the heat pipe through physical pressure without requiring chemical reactions or additional processing steps
Solution Approach 2:
The fixing member is pre-formed with the extended portion and pressing sections designed to automatically engage and secure the heat pipe during installation, eliminating the need for subsequent bonding operations
4Strength
If glue or solder is used to bond the heat pipe to the receiving recess, then the connection strength is improved, but environmental pollution is caused
Solution Approach 1:
The chemical bonding processes that generate pollution are replaced with a mechanical pressing system using the fixing member, which secures the heat pipe through physical force without emitting harmful substances or requiring chemical materials

AI summary
A fixing structure for heat dissipation element includes a base plate, a heat transfer element, and at least one fixing member. The base plate has a top surface, on which a receiving recess is defined for receiving the heat transfer element therein. At least one clearance is defined between the receiving recess and the heat transfer element. The fixing member has a fixing portion and an extended portion. The fixing portion is connected to the top surface of the base plate, whereas the extended portion is bent and inserted into the clearance to locate between the receiving recess and the heat transfer element, such that the heat transfer element is firmly held in the receiving recess of the base plate.
