Description

Technical Field

[0001] This utility model relates to the field of fan housings, and more particularly to housings for water-cooled fans. Background Technology

[0002] Existing water-cooled fan housings are mainly used to support fan components and adapt to water-cooling systems. Their structure usually includes a split design of front and rear housings, which are assembled by fasteners. The housing needs to balance heat dissipation efficiency and installation stability. Some products adopt a modular design to be compatible with fans of different specifications.

[0003] Existing fan housings mostly use screw fixing or clip nesting structures. During installation, tools are needed to align and tighten the screws point by point. Screws are easy to lose during disassembly, which is also very time-consuming and not conducive to the disassembly and assembly work. Summary of the Invention

[0004] In view of this, the present invention provides a housing for a water-cooled fan. The main technical problem to be solved is that the housing is mostly fixed with screws or with a snap-fit ​​structure. During installation, tools are needed to align and tighten the screws point by point. During disassembly, the screws are easy to lose, which is also very time-consuming and not conducive to the disassembly and assembly work.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a housing for a water-cooled fan, comprising a first housing, a mounting groove on the side wall of the first housing, a moving groove on the inner wall of the mounting groove, a double-threaded screw movably mounted on the inner wall of the moving groove, a moving bar threadedly connected to the outer surface of the double-threaded screw, two moving bars, a pressing plate fixedly connected to the side wall of the moving bar, a first bevel gear fixedly connected to the outer surface of the double-threaded screw, a rotating groove inside the first housing, a second bevel gear inside the rotating groove, a rotating shaft fixedly connected to the side wall of the second bevel gear, a second housing on the right side of the first housing, and a mounting frame fixedly connected to the side of the second housing near the first housing, two mounting frames symmetrically distributed vertically, with adjacent pressing plates on the same side located between adjacent mounting frames.

[0006] By adopting the above technical solution, the first and second housings can be disassembled and assembled more efficiently and quickly, without the need for tools, making it more convenient.

[0007] As a further description of the above technical solution:

[0008] A torsion disc is fixedly connected to the side of the rotating shaft away from the second bevel gear, and a protrusion is fixedly connected to the side of the torsion disc away from the rotating shaft.

[0009] By adopting the above technical solution, the protrusion allows the user to easily twist the dial. Twisting the protrusion can drive the dial to rotate, which in turn can drive the rotating shaft and the second bevel gear to rotate.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the first housing has two air outlet slots.

[0012] By adopting the above technical solution, the air outlet duct is used to install the mounting ring.

[0013] As a further description of the above technical solution:

[0014] An installation ring is fixedly connected to the inner surface of the air outlet slot, and an air guide plate is fixedly connected to the inner surface of the installation ring. There are multiple air guide plates.

[0015] By adopting the above technical solution, the air guide plate can guide the blown air.

[0016] As a further description of the above technical solution:

[0017] The first housing has a first ventilation slot on its side wall. There are multiple first ventilation slots, and a first dust filter plate is fixedly connected to the inner surface of the first ventilation slot.

[0018] By adopting the above technical solution, the first dust filter plate can intercept external dust while allowing outside air to enter the interior of the first housing.

[0019] As a further description of the above technical solution:

[0020] The second housing has a second ventilation slot on the side away from the first housing. There are multiple second ventilation slots, and a second dust filter plate is fixedly connected to the inner surface of the second ventilation slot.

[0021] By adopting the above technical solution, the second dust filter can intercept external dust while allowing outside air to enter the interior of the first housing.

[0022] As a further description of the above technical solution:

[0023] The second housing has two heat dissipation fins fixedly connected to the side away from the first housing, and the second dust filter plate is located between adjacent heat dissipation fins.

[0024] By adopting the above technical solution, the heat dissipation fins can dissipate the internal heat of the fan to the outside in a timely manner when the fan is working.

[0025] As a further description of the above technical solution:

[0026] The lower surface of the first housing is fixedly connected to two support legs, and the lower surface of the second housing is fixedly connected to two support legs. The lower surface of the support legs is fixedly connected to shock-absorbing pads.

[0027] By adopting the above technical solution, the support feet can support the first and second housings, and the shock-absorbing pads can reduce the vibration and noise of the fan during operation.

[0028] By employing the above technical solution, the housing of this utility model for a water-cooled fan has at least the following beneficial effects:

[0029] Compared to existing technologies, this housing for a water-cooled fan comprises a first housing, a second housing, a mounting frame, a mounting groove, protrusions, a torsion disc, a rotating shaft, a second bevel gear, a first bevel gear, a double-threaded screw, moving strips, and pressing discs. When installing the first and second housings, the mounting frame is aligned with the mounting groove, bringing the first and second housings closer together until they can no longer be brought closer. The protrusions on both sides are then turned sequentially, causing the torsion disc to rotate. This, in turn, rotates the rotating shaft and the second bevel gear, which in turn rotates the first bevel gear and the double-threaded screw. This causes the adjacent moving strips to move away from each other, thereby causing the two pressing discs to... The inclined surfaces of the upper and lower mounting frames are pressed, causing the mounting frames to be subjected to a leftward component force from the pressing plate. This results in a tighter fit between the first and second housings. When it is necessary to disassemble the first and second housings, simply twist the protrusions in the opposite direction. Compared to existing fan housings, which mostly use screw fixing or snap-fit ​​structures, requiring tools to align and tighten each point during installation, and prone to losing screws during disassembly, this housing for water-cooled fans allows for more efficient and quick disassembly and assembly of the first and second housings without the need for tools, making it much more convenient.

[0040] Reference Figure 1-8The present invention provides a housing for a water-cooled fan, comprising: a first housing 1, a mounting groove 2 on the side wall of the first housing 1, a moving groove 3 on the inner wall of the mounting groove 2, a double-threaded screw 4 movably mounted on the inner wall of the moving groove 3, two moving strips 6 threadedly connected to the outer surface of the double-threaded screw 4, a pressing plate 7 fixedly connected to the side wall of the moving strip 6, a first bevel gear 5 fixedly connected to the outer surface of the double-threaded screw 4, a rotating groove 8 inside the first housing 1, a second bevel gear 9 inside the rotating groove 8, a rotating shaft 10 fixedly connected to the side wall of the second bevel gear 9, a second housing 13 on the right side of the first housing 1, two mounting frames 14 fixedly connected to the side of the second housing 13 near the first housing 1, the mounting frames 14 being symmetrically distributed vertically, with adjacent pressing plates 7 located between adjacent mounting frames 14 on the same side; when the first housing 1 and the second housing 13 need to be installed, the mounting frames 14 are aligned with the mounting groove. 2. Bring the first housing 1 and the second housing 13 closer together until they can no longer get closer. Twist the protrusions 12 on both sides in sequence to rotate the torsion disc 11, which in turn rotates the shaft 10 and the second bevel gear 9, which in turn rotates the first bevel gear 5 and the double threaded screw 4, causing the adjacent moving bars 6 to move away from each other. This causes the two extrusion discs 7 to press against the inclined surfaces of the upper and lower mounting frames 14, so that the mounting frames 14 are subjected to a leftward force from the extrusion discs 7, making the first housing 1 and the second housing 13 fit together more tightly. When it is necessary to separate the first housing 1 and the second housing 13, simply twist the protrusions 12 in the opposite direction. The side of the shaft 10 away from the second bevel gear 9 is fixedly connected to the torsion disc 11, and the side of the torsion disc 11 away from the shaft 10 is fixedly connected to the protrusions 12. The protrusions 12 make it easy for the user to twist the torsion disc 11. Twisting the protrusions 12 can drive the torsion disc 11 to rotate, which in turn drives the shaft 10 and the second bevel gear 9 to rotate.

[0041] Two air outlet slots 15 are formed on the outer wall of the first housing 1. Each air outlet slot 15 is used to install a mounting ring 16. The mounting ring 16 is fixedly connected to the inner surface of each air outlet slot 15. Multiple air guide plates 17 are fixedly connected to the inner surface of each mounting ring 16. The air guide plates 17 can guide the blown air. Multiple first ventilation slots 18 are formed on the side wall of the first housing 1. Multiple first ventilation slots 18 are fixedly connected to the inner surface of each first ventilation slot 18. The first dust filter plate 19 can intercept external dust while allowing outside air to enter the interior of the first housing 1. Multiple second ventilation slots 20 are formed on the side of the second housing 13 away from the first housing 1. A second dust filter plate 21 is fixedly connected to the inner surface of the first housing 1. The second dust filter plate 21 can intercept external dust and allow outside air to enter the interior of the first housing 1. A heat dissipation fin 22 is fixedly connected to the side of the second housing 13 away from the first housing 1. There are two heat dissipation fins 22. The second dust filter plate 21 is located between adjacent heat dissipation fins 22. The heat dissipation fins 22 can dissipate the internal heat to the outside in time when the fan is working. Two support legs 23 are fixedly connected to the lower surface of the first housing 1 and the lower surface of the second housing 13. A shock-absorbing pad 24 is fixedly connected to the lower surface of the support legs 23. The support legs 23 can support the first housing 1 and the second housing 13. The shock-absorbing pad 24 can reduce the vibration and noise when the fan is working.

[0042] Working principle: When it is necessary to install the first housing 1 and the second housing 13, align the mounting frame 14 with the mounting groove 2, and bring the first housing 1 and the second housing 13 closer together until they can no longer get closer. Then, turn the two protrusions 12 in sequence to drive the torsion plate 11 to rotate, which in turn drives the rotating shaft 10 and the second bevel gear 9 to rotate, which in turn drives the first bevel gear 5 and the double threaded screw 4 to rotate, which in turn moves the adjacent moving strips 6 away from each other. This causes the two extrusion plates 7 to press the inclined surfaces of the upper and lower mounting frames 14 respectively, so that the mounting frame 14 is subjected to the leftward component force from the extrusion plates 7, which makes the first housing 1 and the second housing 13 fit more tightly. When it is necessary to separate the first housing 1 and the second housing 13, simply turn the protrusions 12 in the opposite direction.
