Heat Dissipater Fixing Frame for Stable Thermal Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-dissipating structures face reduced efficiency due to displacement and deviation of connecting surfaces between the heat-dissipating structure and the heat-generating element, especially under external forces, as conventional locking mechanisms fail to efficiently press the gravity center of the heat-dissipating structure.
Innovation Solution
A T-shaped positioning frame with a pressing end and transverse rod is integrated into the heat-dissipating base, featuring a sliding groove and screw holes for a locking element, allowing the pressing end to abut the gravity center of the base, ensuring secure connection and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a locking element is used to fix the base of the heat-dissipating structure and the heat-generating element, then the connection strength is improved, but the positioning precision deteriorates because the fixing rod cannot efficiently press the gravity center and only makes point contact
Solution Approach 1:
The fixing rod is segmented into multiple pressing ends that contact different locations on the base, transforming a single point contact into multiple distributed contact points. This segmentation allows the structure to simultaneously achieve strong connection force and precise positioning by distributing the pressing action across multiple areas rather than concentrating it at one point.
Solution Approach 2:
The fixing rod transitions from a single-point contact mechanism to a multi-point contact mechanism by adding vertical segmentation (multiple pressing ends). This dimensional change in the contact interface allows the structure to press the base more effectively at multiple locations simultaneously, improving both connection strength and positioning precision by utilizing additional spatial dimensions for contact.
2Device complexity
If the fixing rod is positioned below the base with screw holes on both ends, then the device complexity is reduced, but the stability deteriorates because the fixing rod bends and slides under external force
Solution Approach 1:
The fixing rod is divided into multiple pressing ends that contact the base at different locations. This segmentation distributes the external forces across multiple contact points, preventing the rod from bending and sliding under load. The structure maintains simplicity while gaining stability through the distributed contact mechanism.
Solution Approach 2:
Different portions of the fixing rod are given different functions: the multiple pressing ends provide localized contact points for stable positioning, while the screw holes provide connection functionality. This local differentiation of quality allows the rod to simultaneously maintain structural stability and functional simplicity without requiring complex additional components.
3Loss of energy
If heat-conducting glue is applied to the connecting surfaces, then the heat conduction efficiency is improved, but the reliability deteriorates because deviation or displacement occurs at the connecting surfaces under external force
Solution Approach 1:
The fixing rod with multiple pressing ends performs preliminary positioning and securing of the base to the heat-generating element before the heat-conducting glue is applied. This preliminary mechanical fixation prevents deviation or displacement during assembly and operation, ensuring that the glue maintains optimal contact and the connection remains reliable under external forces.
Solution Approach 2:
The fixing rod acts as an intermediary mechanical element that provides preliminary stabilization between the base and the heat-generating element. By establishing mechanical contact at multiple points, it creates a stable foundation that allows the heat-conducting glue to function effectively without displacement, combining mechanical and thermal bonding functions.

Function Achieved in This Case
This configuration ensures a stable and efficient heat-dissipating performance by preventing displacement and maintaining contact between the heat-dissipating and heat-generating elements, even under external forces, thereby enhancing thermal conductivity.
Implementation Method 1
Both ends of the fixing rod are provided with a screw hole 104a and 104b, respectively, for connecting to a locking element 11. The fixing action of the locking element 11 produces a downward force.
Implementation Method 2
a heat-conducting medium, so that the base and the heat-generating element can be firmly adhered with each other to perform the heat conduction smoothly

AI summary
A fixing means for a heat dissipater is provided to position the heat dissipater and a heat-generating element, which includes a heat-dissipating base and a positioning frame. The surface of the heat-dissipating base is provided with a plurality of heat-dissipating pieces. The center of the plurality of heat-dissipating pieces is provided with a sliding groove. Further, the positioning frame is formed into a T-lettered shape and constituted of a transverse rod and a pressing end. The pressing end is accommodated in the sliding groove of the base to abut against the surface of the base. Both side faces of the transverse rod are provided with a screw hole, respectively, for receiving a locking element. With the downward force generated by the connection of the locking element, the pressing end of the positioning frame can be caused to abut against the surface of the base, thereby to efficiently press the gravity center of the base and fix the position of the heat dissipater with respect to the heat-generating element.
