Abstract

Technical Field
[0001] The present application relates to the technical field of building construction, and in particular to a heat dissipation device for a weak current machine room. Background Art
[0002] At present, with the development of society, the degree of weak current intelligence is getting higher and higher. Weak current systems such as the Internet, telephone, wireless WIFI, and monitoring have become standard. This requires a special room (weak current room) to manage these systems and exchange data. However, these weak current devices will generate heat when they are running. If the heat is not dissipated in time, it will affect the function and service life of these devices. Usually, a hole is opened on the outer wall of the weak current room, and an axial flow fan is installed therein, so as to achieve the purpose of discharging the hot air in the weak current room. However, the filter screens on the existing axial flow fans are mostly fixed by bolting, which makes it inconvenient to disassemble and assemble the filter screens. For this reason, the inventor has proposed a heat dissipation device for the weak current room. Utility Model Content

[0006] The present application can release the lock on the pressure ring by unscrewing the locking sleeve from the clamping plate, and the filter can be removed after the pressure ring is removed from the clamping groove, thereby improving the convenience of disassembly and assembly of the filter.

[0026] Example 1
[0027] See also Figure 1 This embodiment provides a heat dissipation device for a weak current machine room to solve the problem of inconvenience in assembly and disassembly caused by bolting of the filter screen of the axial flow fan in the existing weak current machine room.
[0028] In this embodiment, the heat dissipation device of the weak current machine room includes an axial flow fan 10 and a filter 20. The filter 20 is clamped between the mounting tube 11 and the pressure ring 30 of the axial flow fan 10. A card slot 12 is provided on the periphery of the mounting tube 11. A card plate 31 that is adapted to be plugged into the card slot 12 is provided on the end face of the pressure ring 30. A locking sleeve 40 that can be screwed together with the card plate 31 is screwed on the outside of the mounting tube 11.
[0029] In this embodiment, the locking sleeve 40 is unscrewed from the clamping plate 31 to release the locking of the pressing ring 30 . After the pressing ring 30 is removed from the clamping groove 12 , the filter screen 20 can be removed, thereby improving the convenience of disassembly and assembly of the filter screen 20 .
[0030] It should be noted that the axial flow fan 10 and the mounting tube 11 are coaxially arranged, and the axial flow fan 10 is fixedly connected to the inside of the mounting tube 11 through the connecting plate, and the locking sleeve 40 is screwed on the outside of the mounting tube 11. Two card grooves 12 are provided at the outer edge of the end surface of the mounting tube 11, and the card grooves 12 extend along the axial direction of the mounting tube 11 as a whole. At the same time, the card grooves 12 are evenly distributed along the circumference of the mounting tube 11, and the threads on the outer wall of the mounting tube 11 are disconnected at the card grooves 12; the pressure ring 30 is coaxially arranged with the mounting tube 11 as a whole, and the inner diameter of the pressure ring 30 is equal to the inner diameter of the mounting tube 11. The outer diameter is equal to the outer diameter of the mounting tube 11, the card plate 31 is fixedly connected to the end face of the pressure ring 30, and the card plate 31 is constructed into an arc-shaped plate that matches the outer shape of the card slot 12. When the card plate 31 is installed in place in the card slot 12, the outer wall of the card plate 31 and the outer wall of the mounting tube 11 are located on the same circumferential surface, and the threads on the outer wall of the card plate 31 are connected to the threads on the outer wall of the mounting tube. The threads on the card plate 31 make up for the thread gap on the mounting tube 11, so that the threads on the outer wall of the mounting tube 11 and the threads on the outer wall of the card plate 31 form a complete thread that can be adapted and screwed with the internal threads on the locking sleeve 30.
[0031] In addition, the axial length of the card plate 31 is greater than the axial length of the card slot 12, and the inner diameter of the card plate 31 is greater than the inner diameter of the pressure ring 30. When the card plate 31 is installed in the card slot 12, there is a gap between the pressure ring 30 and the end face of the mounting tube 11, and the filter screen 20 is clamped in the gap, and the outer diameter of the filter screen 20 is equal to the inner diameter of the card plate 31. The two card plates 31 limit the filter screen 20, thereby ensuring the stability of the filter screen 20 installed on the end face of the mounting tube 11.
[0032] When installing the filter 20 on the installation tube 11, first place the filter 20 against the end surface of the installation tube 11, then insert the clamping plate 31 on the pressure ring 30 into the inside of the clamping groove 12 until the pressure ring 30 is crimped onto the outer surface of the filter 20, and finally screw the locking sleeve 40 toward the pressure ring 30 until the locking sleeve 40 and the clamping plate 31 are threadedly connected, and the installation of the filter 20 is completed.
[0033] When removing the filter 20 from the mounting tube 11, first unscrew the locking sleeve 40 from the clamping plate 31, and then pull the pressure ring 30 axially out of the clamping groove 12. After losing the restriction of the pressure ring 30, the filter 20 will be separated from the mounting tube 11, and the removal of the filter 20 is completed.
[0034] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
