Description

Technical Field

[0001] The utility model relates to the field of chassis fans, in particular to a chassis fan which is easy to assemble and disassemble. Background Art

[0002] A chassis fan generally refers to a fan installed on the outer wall of a chassis, which is used to generate airflow to improve the heat dissipation efficiency of the chassis and ensure that the equipment in the chassis operates at an appropriate temperature.

[0003] Bearings are key components in fans, and their lifespan directly affects the overall lifespan of the fan. The lifespans of bearings of different designs and materials vary greatly, generally ranging from 1,000 to 300,000 hours. Chassis fans in the prior art need to be replaced after performance degradation or damage. The steps for replacing a chassis fan are generally: s1. Open the device case, s2. Release the electrical connection of the fan, s3. Release the fan's connecting bolts and then repeat the above steps in reverse. The overall process is time-consuming. When a large number of fans need to be replaced, it is easy to affect the normal operation of the equipment, increase the equipment maintenance cost and the procedures required for maintenance.

[0004] In summary, the existing chassis fan replacement process is lengthy and difficult to achieve convenient replacement. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0036] The following describes an embodiment of the utility model based on its overall structure.

[0037] Embodiment 1

[0038] A chassis fan that is easy to load and unload, such as Figure 1-2As shown in 5-8, it includes a mounting base 1, which is installed on the chassis wall and has a vent in the center. Specifically, the mounting base 1 can be installed on the inside or outside of the chassis wall. The chassis wall can be the outer wall of an independent box in the chassis or the outer wall of the chassis body. The mounting base 1 is fixedly connected to the chassis wall 9 through a fixing structure. Specifically, the fixing structure is a plurality of connecting screws 7. On the premise of achieving stable fixation of the mounting base 1, bolts or screws can be used for connection, or the mounting base 1 can be connected to a specified position by fixing connections such as bonding. The connecting screws 7 can conveniently and stably fix the mounting base 1 to the desired position, providing a stable connection basis for the subsequent connection of the fan 2. The mounting base 1 is connected to the fan 2 in the vent by a threaded structure, and a contact conductive structure that can cooperate with each other is provided between the fan 2 and the mounting base 1.

[0039] See also Figure 5-8 The mounting base 1 is provided with an internal thread 3 on the inner wall of the vent, and one end of the outer wall of the fan 2 is provided with an external thread 4 that cooperates with the internal thread 3. The part of the mounting base 1 used to connect the fan 2 can be hidden inside the chassis. After the fan 2 is connected to the mounting base 1, the distance protruding from the plane of the outer wall of the chassis is short, which can ensure the flatness of the outer wall of the chassis as much as possible, thereby effectively improving the aesthetics of the fan 2 in the installed state. A disassembly portion is provided at one end of the edge of the fan 2 away from the external thread 4, and the disassembly portion is specifically fixedly connected with at least two rotating ears 8. When installing the fan 2, pinch the rotating ear 8 at the edge of the fan 2, and align the fan 2 with the mounting base 1 to conveniently rotate the fan 2. Specifically, the rotating ear 8 is located at the edge of the fan 2 and protrudes in a direction away from the center of the fan 2, providing a rotating ear structure for the user to twist with fingers. The distance that the rotating ear 8 protrudes along the axial direction of the fan 2 is short, and due to the small size of the rotating ear 8 itself, it does not visually affect the aesthetics of the fan 2 after installation. On the premise of realizing convenient loading and unloading of the fan 2, the disassembly portion can also be a recess with anti-slip patterns or a bayonet for fingers to insert.

[0040] See also Figure 5-8 A conductive seat 5 facing the fan 2 is provided on the mounting seat 1, and a contact 6 is provided on the plane of the fan 2 facing the conductive seat 5. The contact 6 between the fan 2 and the mounting seat 1 and the conductive seat 5 are in contact with each other for electrical conduction, so that the fan 2 can be easily replaced without opening the chassis. The conductive seat 5 corresponds to the contact 6 one by one, and the number is not less than two. Some fans 2 include RGB or ARGB lighting effects. In order to enable the light on the fan 2 to be electrically connected to the mounting seat 1, the conductive seat 5 and the contact 6 between the mounting seat 1 and the fan 2 are also increased.

[0041] Embodiment 2

[0042] A chassis fan that is easy to load and unload, such as Figure 3-4As shown in 9-12, on the basis of Example 1, the difference from Example 1 lies in that the mounting base 1 protrudes from the outer wall of the chassis, and an external thread 4 is provided on the protruding portion, and an internal thread 3 matching the external thread 4 is provided on the inner wall of the fan 2. Since the mounting base 1 protrudes from the plane of the outer wall of the chassis, the fan 2 can be conveniently connected to the mounting base 1 in a handheld state, which can further improve the connection speed between the fan 2 and the mounting base 1, and is suitable for industrial chassis with low requirements on aesthetics.

[0043] The working principle of the utility model is: when the fan 2 needs to be replaced, after the power in the chassis is turned off, the old fan on the chassis is rotated and unscrewed, the mounting base 1 is properly cleaned according to the actual installation situation, and then the new fan 2 is screwed on the mounting base 1 to complete the replacement of the fan 2.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
