Description

Technical Field

[0001] The invention relates to the technical field of computer chassis, in particular to a noise reduction chassis with spoiler-type two-way ventilation. Background Art

[0002] Computers are commonly known as computers. They are modern electronic computing machines used for high-speed calculations. They can perform numerical calculations, logical calculations, and have storage and memory functions. They are modern intelligent electronic devices that can run according to programs and automatically and quickly process massive amounts of data. The core of a desktop computer is the mainframe.

[0003] When the computer is running large software, the CPU and other components will generate heat during high-speed operation, causing the chassis to overheat and have a certain impact on the operation of the system. Efficient heat dissipation is mainly achieved through fan fins, exhaust radiators, circulation pumps and water injection pipes. However, in the heat dissipation process, since air is only drawn into the chassis, the external air is not allowed to circulate quickly to the inside, thereby reducing the heat dissipation efficiency. In addition, the traditional chassis can only cool the inside of the chassis but not the outside, and the noise reduction problem of the chassis is not considered.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a noise reduction chassis with spoiler-type two-way ventilation. The present invention performs spoiler cooling on the interior of the chassis through a cooling fan and a spoiler blower to ensure that the internal temperature of the chassis is normal. At the same time, the cooling fan is an upper and lower fan structure, and the fan blades have opposite angles. While the interior of the chassis is spoiled, the cooling air generated by the lower fan can perform real-time cooling of the chassis shell by adding cooling air outlets around the base. The shock-absorbing plate can eliminate the vibration caused by the chassis to the outside under the support of a number of springs. At the same time, the anti-slip pad can play an anti-slip role.

[0006] To achieve the above advantages, the specific technical scheme adopted by the present invention is as follows: it includes a shell, a base, a cooling fan, a spoiler fan, and a side panel. An air intake port is arranged on the top of the shell, and the side panel is inserted into the side of the shell. The base is installed at the bottom of the shell, and the top of the base is communicated with the interior of the shell. The base includes a bottom plate, an exhaust port, an air duct, a cooling air port, and a groove. Two of the exhaust ports are located on both sides above the bottom plate, and a plurality of the cooling air ports are evenly distributed in an array around the bottom plate. The two spoiler fans are respectively installed above the two exhaust ports by screws. The air duct is arranged inside the bottom plate, and the air duct is communicated with the cooling air port. The groove is located at the bottom of the bottom plate.

[0007] Furthermore, in order to enable the cooling air blown out of the cooling air outlet to cool the outer shell, the air outlet angle of the cooling air outlet is toward the outer shell.

[0008] Furthermore, in order to achieve the effects of turbulence and cooling and exhausting air, the turbulence fan includes a motor, upper air blades and lower air blades, and the upper air blades and lower air blades are symmetrically installed on the upper and lower sides of the motor, and the air blades of the upper air blades and the lower air blades are opposite.

[0009] Furthermore, in order to prevent a large amount of dust from entering and to facilitate the cleaning of the filter, a filter is provided on the air inlet, and magnets are provided around the inner side of the filter.

[0010] Furthermore, in order to allow the base to play a shock-absorbing and anti-slip role, a shock-absorbing plate is provided at the bottom of the groove, a number of springs are installed between the shock-absorbing plate and the groove, and anti-slip pads are provided around the bottom of the groove.

[0011] Furthermore, in order to allow the air volume at the bottom of the spoiler fan to be completely blown into the interior of the exhaust port, a sealing gasket is provided above the exhaust port.

[0012] Furthermore, in order to allow the cooling air blown out by the cooling fan to be turbulent through the turbulent fan, the vertical positions of the cooling fan and the turbulent fan correspond to each other.

[0013] Compared with the prior art, the present invention provides a noise reduction chassis with spoiler-type two-way ventilation, which has the following beneficial effects: the present invention uses a cooling fan and a spoiler fan to perform spoiler cooling on the interior of the chassis to ensure that the internal temperature of the chassis is normal. At the same time, the cooling fan is an upper and lower fan structure, and the fan blades have opposite angles. While the interior of the chassis is spoiled, the cooling air generated by the lower fan can add cooling air outlets around the base to cool the outer shell of the chassis in real time. The shock-absorbing plate can eliminate the vibration caused by the chassis to the outside under the support of a number of springs, and the anti-slip pad can play an anti-slip role.

DETAILED DESCRIPTION

[0017] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] According to an embodiment of the present invention, a noise reduction chassis with spoiler-type two-way ventilation is provided.

[0019] The present invention is further described with reference to the accompanying drawings and specific embodiments. Figure 1-9 As shown, a spoiler-type two-way ventilation noise reduction chassis according to an embodiment of the present invention comprises a shell 1, a base 2, a cooling fan 3, a spoiler fan 4, and a side panel 5. An air intake port 11 is arranged on the top of the shell 1, and the side panel 5 is inserted into the side of the shell 1. The base 2 is installed at the bottom of the shell 1, and the top of the base 2 is communicated with the interior of the shell 1. The base 2 comprises a bottom plate 21, an air outlet 22, an air duct 23, a cooling air outlet 24, and a groove 25. The two air outlets 22 are located on both sides above the bottom plate 21, and a plurality of the cooling air outlets 24 are evenly distributed in an array around the bottom plate 21. The two spoiler fans 4 are respectively installed above the two air outlets 22 by screws 6. The air duct 23 is arranged inside the bottom plate 21, and the air duct 23 is communicated with the cooling air outlet 24. The groove 25 is located at the bottom of the bottom plate 21.

[0020] In one embodiment, the outlet angle of the cooling air outlet 24 is toward the housing 1 , and when the spoiler fan 4 is working, the lower air blades 43 send air to the cooling air outlet 24 through the exhaust port 22 and the air duct 23 to cool the outside of the housing 1 .

[0021] In one embodiment, the spoiler fan 4 includes a motor 41, upper air blades 42 and lower air blades 43. The upper air blades 42 and the lower air blades 43 are symmetrically installed on the upper and lower sides of the motor 41, and the air blades of the upper air blades 42 and the lower air blades 43 are opposite. When the motor 41 rotates, the air volume generated by the upper air blades 42 and the cooling air blown out by the cooling fan 3 form a spoiler collision to cool the interior of the chassis. Driven by the rotation of the motor 41, the lower air blades 43 send the cooling air from the exhaust port 22 and the air duct 23 to the cooling air port 24 to cool the outside of the shell 1.

[0022] In one embodiment, a filter screen 7 is provided on the air inlet 11, and the filter screen 7 can perform primary filtration of external impurities. Magnets 71 are provided around the inner side of the filter screen 7, and the filter screen 7 can be quickly and conveniently installed through the magnets 71.

[0023] In one embodiment, a shock-absorbing plate 251 is provided at the bottom of the groove 25, and a plurality of springs 252 are installed between the shock-absorbing plate 251 and the groove 25. The shock-absorbing plate 251 can eliminate the vibration brought to the outside by the chassis with the support of the plurality of springs 252. Anti-skid pads 253 are provided around the bottom of the groove 25, and the anti-skid pads 253 can play an anti-skid role.

[0024] In one embodiment, a sealing gasket 221 is disposed above the air outlet 22 , and the sealing gasket 221 can ensure that the cooling air generated by the lower air blades 43 driven by the rotation of the motor 41 can completely enter the interior of the air duct 23 .

[0025] In one embodiment, the vertical positions of the cooling fan 3 and the spoiler fan 4 correspond to each other, so that the cooling air blown out by the cooling fan 3 can be spoiled by the upper air blades 42 and discharged from the air holes on the side panel 5 to ensure the temperature balance inside the chassis.

[0026] Working principle: When in use, the cooling fan 3 and the spoiler fan 4 operate in real time. The cooling fan 3 draws external air into the interior of the chassis from the air inlet 11. The air inlet 11 is provided with a filter 7, which can perform primary filtration of external impurities to prevent dust from falling into the interior of the chassis. Magnets 71 are provided around the inner side of the filter 7, and the filter 7 can be quickly and conveniently installed through the magnet 71. The cooling fan 3 cools the components inside the chassis in real time. At the same time, the upper wind blades 42 on the spoiler fan 4 correspond to the cooling air blown out by the cooling fan 3 under the rotation of the motor 41. The wind is impacted by turbulence and discharged from the air holes on the side panel 5, ensuring the temperature balance inside the chassis. At the same time, when the motor 41 rotates, the lower air blades 43 rotate to generate cooling air, which is sent to the cooling air outlet 24 through the exhaust port 22 and the air duct 23 for discharge. The outlet angle of the cooling air outlet 24 is toward the outer shell 1, so that the cooling air outlet 24 blows the cooling air directly onto the outer shell 1 of the chassis, and cools the outer shell 1 in real time. The shock absorbing plate 251 can eliminate the vibration caused by the chassis to the outside with the support of a plurality of springs 252, and the anti-skid pad 253 can play an anti-skid role.

[0027] To sum up, with the help of the above-mentioned technical scheme of the present invention, the present invention realizes the turbulence cooling of the interior of the chassis by the cooling fan and the turbulence fan to ensure the normal temperature inside the chassis. At the same time, the cooling fan is an upper and lower fan structure, and the blade angles of the fan are opposite. While turbulence is performed inside the chassis, the cooling wind generated by the lower fan can increase cooling air outlets around the base to cool the outer shell of the chassis in real time. The shock-absorbing plate can eliminate the vibration brought to the outside by the chassis under the support of several springs. At the same time, the anti-slip pad can play an anti-slip role.
