Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a modular fan. Background Technology

[0002] Electronic devices generate a lot of heat when they are operating. This heat causes the device's temperature to rise, and if the heat cannot be effectively dissipated, the device's reliability and performance will decrease. To prevent electronic devices from overheating, fans are used to effectively dissipate the heat generated, thereby ensuring the device functions properly.

[0003] As the processing speed and performance of electronic devices such as central processing units increase, the heat they generate also increases. As a result, single fans are sometimes no longer sufficient to meet the heat dissipation requirements. In this case, combined fans have emerged, which are composed of multiple single fans connected together to form a combined fan for heat dissipation.

[0004] In existing technologies, some fans are fixed together by adding an extra connector on the outside of the fan, while others are connected by a protruding male connector on the side of the fan to a female connector on another fan. Furthermore, fan connections involve not only hardware connections but also electrical connections. However, in practical use, it has been found that the existing methods, where hardware and electrical connections are separate, cause inconvenience during assembly. Additionally, the connectors cannot be stored inside the fan, thus increasing the size of the individual fan. In other words, the space required for individual use when combining individual fans increases.

[0005] Therefore, it is necessary to provide a modular fan to solve the above-mentioned technical problems, which is an urgent issue that needs to be addressed. Utility Model Content

[0010] In the aforementioned modular fan, the bottom and top of the first sliding connector are respectively provided with a first slot and a second slot. The first slot engages with the first engaging portion, and the second slot engages with the third engaging portion. The bottom and top of the first sliding connector are also respectively provided with a first slide table and a second slide table. The first slide table is disposed in the first slide groove, and the second slide table is disposed in the third slide groove. The first sliding connector is driven to slide by the first slide table and the second slide table.
