Concealed Latch Radiating Fin Assembly for Secure Heat Sink Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiating fin assemblies have poor appearance and security due to exposed latching structures, which are prone to deformation and loosening under external forces.
Innovation Solution
The radiating fin design features a main body with perforations and extension sections that include latch plates, allowing for secure latching without exposing the latching mechanism, providing a concealing effect and enhanced connection security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If latch ends and latch sections are disposed on bending edges for connection, then radiating fins can be assembled together, but the latching structures are exposed and appearance is poor
Solution Approach 1:
The latch ends and latch sections are nested within perforations of the radiating fin body, with latch plates passing through perforations to achieve concealed connection. The latching structures are hidden inside the fin assembly rather than exposed on the surface, resolving the contradiction between assembly capability and appearance quality.
2Ease of manufacture
If latch ends and latch sections are disposed on bending edges, then connection is achieved, but structures deform under external force and security is poor
Solution Approach 1:
The latching structures are nested within the rigid body of the radiating fin through perforations, protecting them from external force deformation. The latch plates pass through the fin body to secure adjacent fins, preventing loosening and detachment while maintaining connection security under external loads.
Solution Approach 2:
The connection structure is segmented into distinct components: latch plates, latch ends, latch sections, and perforations. This segmentation allows each component to perform its specific function optimally, with latch plates providing rigid connection and perforations providing protected pathways, thereby improving overall connection security.
3Ease of manufacture
If conventional latching structures are used, then radiating fins can be connected, but the structures are prone to loosening and detachment
Solution Approach 1:
The latch ends and latch sections are nested within the fin body perforations, creating a stable, protected connection that resists loosening and detachment. The nested configuration maintains consistent engagement between fins throughout operation.
Solution Approach 2:
The latch plates are pre-formed on the extension sections before assembly, and the perforations are pre-formed in the fin body. This preliminary preparation ensures proper alignment and stable connection during the assembly process, preventing subsequent loosening.

AI summary
A radiating fin and a connection structure composed of multiple radiating fins. Each radiating fin has a main body formed with a first plane face. A first bending edge and a second bending edge extend from two sides of the first plane face. The first plane face is formed with a first perforation and a second perforation and a third perforation and a fourth perforation. A first extension section and a second extension section respectively from the first and second bending edges. Two front ends of the first extension section are bent and formed with a first latch plate and a second latch plate. Two front ends of the second extension section are bent and formed with a third latch plate and a fourth latch plate. The latch plates of a forward radiating fin are correspondingly passed through and latched in the perforations of an adjacent rearward radiating fin.
