Description

Technical Field

[0001] This utility model relates to a high thermal conductivity locking device, and more particularly to a composite structure high thermal conductivity locking strip, which is suitable for fields such as heat dissipation of electronic equipment and precision mechanical fixing, and can simultaneously achieve efficient heat conduction and mechanical locking functions. Background Technology

[0002] In fields such as electronic equipment, power systems, and precision machinery, locking devices are often required to secure components, while also demanding good thermal conductivity between components to achieve rapid heat transfer and dissipation. Traditional locking strips are mostly made of a single metal material, which, while possessing a certain structural strength, has limited thermal conductivity and is insufficient to meet the heat dissipation requirements of high-power equipment.

[0003] In existing technologies, some solutions employ the addition of thermally conductive pads to improve the thermal conductivity of locking devices. However, during the locking process, the relative displacement between components can easily cause the thermally conductive pads to separate from the contact surface, interrupting the heat conduction path. Furthermore, while some highly thermally conductive materials (such as graphene composites) are used in heat conduction components, how to organically integrate them with the locking structure to ensure reliable locking while maintaining continuous and efficient heat conduction remains a pressing technical problem.

[0004] Therefore, developing a composite locking strip that can achieve stable locking function and has excellent and continuous thermal conductivity has important practical application value. Summary of the Invention

[0012] Furthermore, the front end block and the end block are slidably engaged with the first limiting groove of the first high thermal conductivity graphene-metal composite plate through the first mating structure, and are connected to the base by screws; threaded holes are opened at both ends of the base, and threaded through holes coaxial with the threaded holes are opened on the front end block and the end block respectively.
