Description

Technical Field

[0001] The utility model relates to the technical field of flexible heat sinks, and more specifically to a flexible heat sink structure. Background Art

[0002] Heat sinks transfer heat energy from heat generating components to the environment by convection, radiation or further conduction. Heat sinks usually have an extended surface to promote heat dissipation to the environment. Aluminum (or other metals, such as copper) protrusions are a common form of heat sinks. These protrusions have a rigid base and extended surface fins. Metal heat sinks generally conduct electricity and may cause electromagnetic interference problems in electronic devices. Other forms of metal heat sinks include flexible copper foils of various shapes, optionally with an insulating coating on one or both major surfaces. Ceramic, metal and sintered heat sinks are generally rigid.

[0003] There are generally two types of heat sinks currently in use, hard heat sinks and flexible heat sinks. Existing flexible heat sinks are generally fixed in place by a magnetic structure on the surface. Such a structural setting still has some problems during use. Since the magnetic structure is a contact connection method, it is easy to accidentally touch and drop during use. In addition, due to the thin structure, it is difficult to detect if it falls, affecting the use effect of the flexible heat sink. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a flexible heat sink structure to solve the problems existing in the above background technology.

[0011] Further: a fixing ring sleeve is installed inside the connecting hole, an annular groove communicating with the connecting hole is arranged on the upper side of the connecting plate, and a first limiting ring combined with the annular groove is arranged on the upper side of the fixing ring sleeve.

[0012] Technical effects and advantages of the utility model:

[0013] 1. The utility model can conveniently fix the installation position of the heat sink through the magnetic surface at the bottom of the heat sink. The cooperation of the limiting round block, the connecting plate, the connecting hole and the adhesive pad can enhance the limiting effect of the heat sink and improve the stability of the position.
