Description

Fixing device with heat dissipation effect

The present invention provides a fixture with a heat dissipation effect, particularly a fixture capable of diffusing heat sources to enhance heat dissipation. Positioning mechanisms are assembled at each corner of the base, and a heat pipe can extend outward from at least one side of the base to accommodate at least one auxiliary heat dissipation unit, thereby enhancing the fixture's heat dissipation performance.

With the rapid development of industrial technology, various industrial products such as computers, televisions, telephones, refrigerators, washing machines, wardrobes, drawers, and desks have long become indispensable items in people's lives. These industrial products are often assembled from multiple components, such as the outer casing of a computer, the circuit board and heat sink inside a television casing, the desktop panel and supporting side panels of a desk, or the board-to-board assembly between two opposing circuit boards. These components are often fastened together using screws, allowing the product to be disassembled into multiple parts for easy transportation. The assembled product can also be partially disassembled for repair or replacement.

For applications such as circuit boards and heat sinks within computer or television housings, or for board-to-board assembly between two opposing circuit boards, a heat sink must be installed to assist the heat sink in dissipating heat. Heat sinks mounted on the heat sink can also be screwed to the circuit board surrounding the heat sink. However, space must be left around the heat sink for the screws, preventing the heat sink from dissipating heat. This compromises the heat sink's effectiveness and creates complications and challenges during its manufacture.

Furthermore, since the various components of these industrial products or circuit boards are assembled and connected together through screws, the surfaces of the components that are pressed by the screw heads during assembly often suffer damage such as dents and cracks due to overtightening. To address the aforementioned component damage caused by screws, some manufacturers use welding to assemble the components. However, this design makes it difficult to disassemble some components of the assembled industrial product, making repair or replacement difficult.

Therefore, manufacturers in this industry are urgently seeking solutions to the current problems and difficulties associated with screw fastening, such as damage to panels, difficulty in disassembly, and the impact of assembly on panels on their structure and performance.
