Thermal Module Assembling Structure with Deformed Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal module assembling structures fail to securely prevent heat pipes from being extracted out of the receiving channel along the lengthwise direction due to the ribs and channel design, which only embrace the circumferential surface of the heat pipe.
Innovation Solution
The thermal module assembling structure features locally deformed connection sections between the ribs and the heat pipe, where the deformed raised portions on the ribs and recessed portions on the heat pipe are engaged to form a tight, interference fit that is normal to the heat pipe's axis, preventing extraction along its length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the ribs and receiving channel simply embrace the circumferential surface of the heat pipe, then the structure is simple and easy to manufacture, but the heat pipe can still be extracted out of the receiving channel along its length
Solution Approach 1:
The patent changes the physical state of the rib structure from rigid to deformable by applying external force during assembly. The rib is pressed to deform and wrap around the heat pipe, creating a secure mechanical interlock that prevents extraction while maintaining manufacturing simplicity
Solution Approach 2:
The rib structure transitions from a static, rigid component to a dynamic, deformable element during the assembly process. The rib is pressed to deform and then maintains its deformed state, creating an adaptive connection that secures the heat pipe without requiring complex manufacturing
2Reliability
If the ribs are pressed to deform and wrap around the heat pipe to form a tight fit, then the heat pipe is securely restricted from extraction, but the manufacturing process becomes more complex
Solution Approach 1:
The rib structure is pre-designed with the capability to deform and wrap around the heat pipe. The deformation action is performed as a preliminary step during assembly before final positioning, ensuring secure attachment without requiring additional complex fastening mechanisms
Solution Approach 2:
The rib structure performs its own securing function by deforming and wrapping around the heat pipe itself, eliminating the need for separate fasteners, adhesives, or additional locking mechanisms. The rib serves both as a structural support and as the securing element
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
This design effectively restricts the heat pipe from being removed from the receiving channel, ensuring secure integration and enhanced thermal performance by maintaining the heat pipe's position within the channel.
Implementation Method 1
the lower surfaces of the ribs and the surface of the heat pipe are deformed to form at least one deformed connection section between the lower surfaces of the ribs and the surface of the heat pipe
Implementation Method 2
the deformed connection section is substantially normal to an axis of the heat pipe so as to apply an interference force to the heat pipe to prevent the heat pipe from being extracted out of the receiving channel along the length thereof

AI summary
A thermal module assembling structure includes a heat dissipation board and at least one heat pipe. The heat dissipation board has a receiving channel for fitting the heat pipe therethrough. Two sides of upper side of the receiving channel are respectively formed with two ribs. The ribs horizontally protrude and extend toward the middle of the receiving channel to face the heat pipe fitted in the receiving channel. At least one deformed recess is formed on an upper surface of each of the ribs, whereby the lower surfaces of the ribs and a surface of the heat pipe are deformed to form at least one deformed connection section between the lower surfaces of the ribs and the surface of the heat pipe. By means of the restriction of the deformed connection section, the heat pipe is prevented from being extracted out of the receiving channel.
