[0031] Traditional heat sinks suffer from complex assembly and disassembly, unreliable electrical connections, limited functionality, and excessive thickness. In particular, traditional air-cooled heat sinks often use screws or clips to secure the top cover to the main body, requiring the removal of multiple fasteners during component replacement or maintenance, which can easily damage the interfaces.

[0032] To address the shortcomings and problems of existing heat sinks, this disclosure provides a heat sink top cover connection structure and a CPU heat sink. Through magnetic positioning, cavity flat laying, and elastic conductivity, it achieves quick assembly / disassembly, ultra-thin design, and functional expansion. Specific embodiments and accompanying drawings are described below. Figure 1 -Appendix Figure 3 The present invention will be further elaborated and explained.

The first magnetic array 11 and the second magnetic array 61 use magnets of opposite polarities, or a combination of magnets and magnetic materials. The magnetic attraction structure of the radiator's top cover allows for quick assembly and disassembly of the top cover from the support, facilitating maintenance. Furthermore, the top cover adopts a compartmentalized layout, with electrical components laid flat within the corresponding compartments, optimizing heat distribution and reducing the space occupied by the top cover.
