Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for fixing heat pipes to heat dissipation components, such as welding and press fit, face issues like loosening due to vibrations, material incompatibility, and damage to capillary structures, leading to thermal resistance and environmental concerns.
Innovation Solution
A heat pipe fixing structure comprising a heat pipe, a carrier body with a channel, and first and second fixing members, where the heat pipe is inserted through a channel with the fixing members applying pressure to securely attach it to the carrier body, avoiding deformation and thermal resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to connect heat pipe with heat dissipation component, then connection strength is improved, but thermal resistance and environmental pollution worsen
Solution Approach 1:
The patent introduces a fixing structure comprising a carrier body and fixing members as an intermediary between the heat pipe and heat dissipation component. This intermediary mechanism achieves secure connection through mechanical engagement (channels, recesses, and fixing members) without direct welding, thereby eliminating thermal resistance and environmental pollution associated with welding processes while maintaining strong connection
2Ease of manufacture
If press fit structure is used to fix heat pipe, then connection simplicity is improved, but heat pipe deformation and capillary structure damage worsen
Solution Approach 1:
The patent segments the connection function into multiple components: the carrier body with channels, the heat pipe with recesses, and fixing members. This segmentation allows the heat pipe to be engaged through the channel without direct press fit, preventing deformation of the heat pipe and damage to its capillary structure while maintaining manufacturing simplicity
Solution Approach 2:
The heat pipe is nested within the channel of the carrier body, with the fixing members positioned to secure the heat pipe in place. This nested arrangement protects the heat pipe from direct pressing forces that would cause deformation, while still achieving secure connection through the combined structure
3Strength
If solder paste or heat conduction paste is used to adhere heat pipe, then adhesion is improved, but material incompatibility and reliability worsen
Solution Approach 1:
The patent uses the fixing structure (carrier body and fixing members) as an intermediary mechanical connection system that eliminates the need for solder paste or heat conduction paste. This mechanical engagement approach avoids material incompatibility issues between copper/aluminum heat pipes and dissimilar materials in adhesive compounds, while achieving reliable adhesion through precise geometric fitting

AI summary
A heat pipe fixing structure includes a heat pipe, a carrier body and a first fixing member. The heat pipe has a main body having a first side and a second side. The carrier body has a channel having an open side and a closed side. The heat pipe is disposed in the channel with the first and second sides respectively corresponding to the open side and the closed side. The first fixing member is disposed on upper side of the heat pipe and upper side of the carrier body. A free end of the first fixing member is in corresponding contact with the first side of the heat pipe to press and abut against or engage with the heat pipe. The heat pipe fixing structure serves to firmly fix the heat pipe to eliminate the shortcomings existing in the conventional welding process for fixing the heat pipe.
