Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation water cooling heads, in particular to a magnetic suction fan group. Background Art

[0002] CPU is the abbreviation of central processing unit. CPU is one of the main devices of electronic computers and also the core component of computers. CPU will generate a lot of heat when working. If the heat is not dissipated in time, it may cause a crash at best and the CPU may be burned out at worst. When the CPU is working, it is usually chosen to install a fan for heat dissipation.

[0003] As computing power requirements continue to increase, the heat dissipation requirements for the CPU are also getting higher and higher. In order to enhance the heat dissipation effect of the fan, most manufacturers use multiple fans to splice into a fan group to increase the air volume, thereby improving the overall heat dissipation performance of the chassis.

[0004] In the prior art, snap-on connection or magnetic connection is often used to achieve the splicing of multiple fans. For example, the utility model patent with publication number CN220752635U discloses a connection mechanism for a combined computer case fan, including at least two groups of magnetic components with the same structure and horizontally distributed, each group of fan housings has two groups of symmetrically arranged magnetic components fixed on the outer wall in the horizontal arrangement direction, and each adjacent two groups of fan housings are magnetically connected by two corresponding groups of magnetic components, one group of magnetic components is the S pole of the magnet, and the other group of magnetic components is the N pole of the magnet, and each adjacent two groups of fan housings are magnetically fixed to each other by the S pole of the magnet and the N pole of the magnet. The connection mechanism of the combined computer case fan can be used to pre-fix two adjacently distributed fans by arranging corresponding magnetic components on both sides of the fan, and the magnetic components can achieve an adsorption effect, enhance the flatness of the combination of multiple fans, improve the beauty of the fans, and form multiple fans into a whole, ensuring that multiple fans can correspond neatly.

[0005] The magnetic connection structures currently used in the market are mostly similar to the solution of the utility model patent mentioned above, which requires magnets with different magnetic poles to be configured on different sides of the fan, which undoubtedly increases the difficulty of production and reduces production efficiency. In addition, the magnets are usually embedded in the frame of the fan, separated by a plastic layer and a corresponding distance, resulting in a weak magnetic attraction force and insufficient stability during splicing.

One side of the light guide component is connected to the light output surface of the light source, and the other side extends to the light output gap. The light emitted by the light source is transmitted to the light output gap through the light guide component, and undergoes multiple reflections and transmissions of the semi-transparent sheet and multiple reflections of the total reflection lens, so as to form multiple lighting effects with the same shape as the light output gap and distributed at intervals.

DETAILED DESCRIPTION

[0028] The utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Example 1: Figures 1 to 7As shown, a magnetic suction fan group includes more than two fan bodies 1. In this embodiment, three fan bodies 1 are arranged as a group. Adjacent fan bodies 1 are magnetically connected through magnetic suction components. In this embodiment, two sets of magnetic suction components are arranged between adjacent fan bodies 1. The two sets of magnetic suction components are arranged at a certain distance to ensure a relatively stable magnetic suction effect. The magnetic suction component includes a first magnetic suction component independent of the fan body 1 and a second magnetic suction component arranged on the fan body 1. Adjacent fan bodies 1 are spliced ​​into one by the magnetic suction effect of the first magnetic suction component and the second magnetic suction component. The first magnetic suction component is provided with a magnet 2, and the second magnetic suction component is provided with a magnet 2 or a magnetic material. In this embodiment, the second magnetic suction component is provided with a magnetic material, and the magnetic material in this embodiment is an iron sheet 3. Since the first magnetic attraction component is independent of the fan body 1, it can be directly contacted and connected with the second magnetic attraction component, and the magnetic attraction effect will not be affected by the plastic isolation of the fan body 1, so that the magnetic attraction force is stronger and the splicing is more secure; and since the first magnetic attraction component is provided with a magnet 2, and the second magnetic attraction component is set to a magnetic material, the magnetic material has no magnetic pole direction, the magnet 2 can magnetize the magnetic material and attract each other, the magnetic material can be directly configured without identifying the direction, which can significantly improve the efficiency of assembly.

[0030] Specifically, the outer wall of the fan body 1 is provided with a groove 4 adapted to the end of the first magnetic attraction component, and a slot 5 for embedding the second magnetic attraction component is provided in the groove 4. In this embodiment, an iron sheet 3 is used as the second magnetic attraction component and is embedded in the slot 5. The first magnetic attraction component includes a magnet 2 and a shell wrapped around the outer surface of the magnet 2. The shell and the magnet 2 are injection molded by in-mold injection. A through hole 6 is provided in the middle of the magnet 2, and a connecting column 7 passing through the through hole 6 is provided on the inner side of the shell. The outer wall of the shell is provided with a recess 8 for easy grasping. Openings 9 are provided at both ends of the shell, and the two ends of the magnet 2 are respectively exposed at the openings 9. When two adjacent fan bodies 1 are spliced, the two ends of the magnet 2 are respectively inserted into the groove 4 and directly contact and magnetically connect with the second magnetic attraction component.

[0031] More specifically, the fan body 1 includes a frame 10 and a light unit, a fan blade assembly 11 is installed in the middle of the frame 10, and the light unit is arranged on the outer wall of the frame 10. The light unit includes a light source 12, a light guide assembly 13, a semi-transparent lens 14 and a total reflection lens 15 arranged in parallel and spaced apart, the semi-transparent lens 14 is arranged on the outside of the total reflection lens 15, the reflection surface of the total reflection lens 15 faces one side of the semi-transparent lens 14, and a light exit gap is arranged at the end of the total reflection lens 15, one side of the light guide assembly 13 is connected to the light exit surface of the light source 12, and the other side extends to the light exit gap, and the light emitted by the light source 12 is transmitted to the light exit gap through the light guide assembly 13, and after multiple reflections and transmissions of the semi-transparent lens 14 and multiple reflections of the total reflection lens 15, a plurality of light effects with the same shape as the light exit gap and spaced apart are formed. A spring 16 is arranged on one side of the fan body 1, and a wiring seat 17 is arranged on the other side of the fan body 1, and adjacent fan bodies 1 are electrically connected by the abutment of the spring 16 and the wiring seat 17. Light units are disposed on both sides of the fan body 1 , and a digital display unit 18 is disposed on one side of the light unit on one side for displaying the fan speed.

[0032] The disassembly and assembly principle of this embodiment is as follows: during splicing, first place the first magnetic attraction component in the groove 4 of one fan body 1 (referred to as the first fan body 1). Due to the magnetic attraction between the first magnetic attraction component and the second magnetic component in the groove 4, one end of the first magnetic attraction component is inserted into the groove 4 to complete the installation of the first magnetic attraction component. Next, place the other fan body 1 (referred to as the second fan body 1) close to one side of the first fan body 1, align the groove 4 of the second fan body 1 with the installation position of the first magnetic attraction component, and insert the other end of the first magnetic attraction component into the groove 4 of the second fan body 1. At the same time, the second magnetic attraction component in the groove 4 of the second fan body 1 contacts and magnetically attracts the end of the first magnetic attraction component to complete the splicing of the two adjacent fan bodies 1. During disassembly, apply external force in opposite directions to separate the first fan body 1 and the second fan body 1. At this time, the same first magnetic attraction component will remain in the groove 4 of the first fan body 1 or the second fan body 1, and then be taken out of the groove 4 by grasping the recessed position 8 of the housing of the first magnetic attraction component to complete the disassembly.

[0033] Example 2: The difference between this example and Example 1 is that a light unit is provided on one side of the fan body and a liquid crystal display screen is provided on the other side. When the three fan bodies are spliced ​​into one, the three liquid crystal display screens are also connected in a row. By setting the control program, the three screens can display different areas of the same picture to achieve multi-screen linkage display and present a better display effect.

[0034] The above is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment. There may be local minor structural changes during the implementation process. If the various changes or modifications to the present invention do not deviate from the basic principle and scope of the present invention and fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
