Description

Technical Field

[0001] The present application belongs to the technical field of mechanical equipment, and specifically relates to a fan device and processing equipment. Background Art

[0002] For devices with high power consumption, cooling fans are typically installed to guide cool air into the device for heat dissipation. To ensure both cool air and dust prevention, dust screens are typically installed at the air inlet. However, if the device is used for extended periods without timely cleaning, the dust screens can become clogged with dust, reducing the airflow and affecting the device's cooling performance. Summary of the Invention

[0003] The technical problem to be solved by this application is that if the existing dust-proof net used for gas entering the equipment is used for a long time and is not cleaned in time, the dust-proof net will be blocked and the air intake volume will decrease, affecting the heat dissipation effect. In order to solve this technical problem, a fan device and processing equipment are provided that can avoid the blockage of the dust-proof net and ensure the heat dissipation effect.

[0004] The technical solutions proposed in this application are: A fan device, comprising: a mounting block having a channel; A fan is provided at the first end of the channel, and the fan can rotate forward and reverse; a dustproof net, disposed at the second end of the channel; An air guide assembly is disposed in the channel and is configured to rotate about an axial rotation axis of the channel, the air guide assembly is capable of forming active air vents and normally open air vents in the channel, and the active air vents and the normally open air vents are arranged in sequence around the rotation axis, and the air guide assembly is configured to open and close the active air vents; When the fan rotates forward, the active air vent opens, and the air flow in the channel flows toward the fan through the active air vent and the normally open air vent; When the fan rotates in reverse, the movable air port is closed, the air flow in the channel flows toward the dustproof net through the normally open air port, and the air guide assembly rotates under the action of the air flow.

[0005] When the above-mentioned fan device is used, when the equipment is dissipating heat, the fan rotates forward, guiding the cold air from the outside to penetrate into the interior of the equipment through the active air vents and the normally open air vents. The large circulation area can ensure that the air intake flow meets the heat dissipation requirements, and the dust screen filters the outside air; when there is a lot of dust on the dust screen, the fan reverses, the active air vents are closed, and the air flow is blown toward the dust screen through the normally open air vents to blow off the dust on the dust screen, avoid clogging of the dust screen, and ensure the heat dissipation effect of the processing equipment. At the same time, when the fan reverses, since the active air vents are closed, the air flow in the channel is blown toward the dust screen through the normally open air vents, and the gas flow area is reduced, thereby increasing the gas flow rate, thereby increasing the impact of the air flow on the dust screen, and ensuring that the dust on the dust screen is blown off. In addition, the air guide assembly rotates under the action of the air flow, and the normally open air vents rotate accordingly, thereby increasing the dust removal area of the dust screen, blowing off the dust on the dust screen as much as possible, and improving the dust removal effect of the dust screen.

[0006] Furthermore, the air guide assembly includes a connecting block and a plurality of blades movably connected to the connecting block, the connecting block is rotatably disposed in the channel, and the movable air outlet and the normally open air outlet are formed between the connecting block and the inner wall of the channel; The movable air outlet can be opened and closed during the movement of the plurality of blades.

[0007] Furthermore, each of the blades is capable of rotating between an on position and a off position; When each of the blades is located at the conducting position, the active air vent is opened; when each of the blades is located at the closing position, the active air vent is closed.

[0008] Furthermore, when the fan rotates forward, each of the blades can be rotated to the on position under the action of the airflow; when the fan rotates reversely, each of the blades can be rotated to the off position under the action of the airflow.

[0009] Furthermore, the air guide assembly also includes a plurality of reset members, each of which is connected between the blade and the connecting block, and the reset member can provide a force to rotate the blade to the closed position or the conducting position.

[0010] Furthermore, the movable air vent is connected to the normally open air vent; When each of the blades is in the closed position, the multiple blades form a power flow path toward one side of the fan, both ends of the power flow path extend to the normally open air outlet, and one end of the power flow path gradually moves away from the fan to the opposite other end.

[0011] Furthermore, the air guide assembly further includes a driving module, wherein the driving module is connected to the plurality of blades to drive the blades to rotate between the conducting position and the closed position; The fan device further includes a control module, and the driving module and the fan are both electrically connected to the control module.

[0012] Furthermore, the dustproof net has a ventilation area and a cooling area, and the ventilation area is arranged around the cooling area; The fan device further includes a cooling block, which is arranged in the cooling area and is used to cool the dustproof net.

[0013] Furthermore, during the rotation of the air guide assembly, the path area during the rotation of the normally open air outlet corresponds to the ventilation area.

[0014] A processing device comprises the fan device as described above.

[0015] In summary, the fan device and processing equipment provided by this application have at least the following advantages: 1. When the fan rotates forward and air enters the device, the active air vents and the normally open air vents open, and the dust screen filters the incoming air. When the fan rotates backward, the active air vents close, and air flows from the normally open air vents to the dust screen, increasing the air flow speed. At the same time, the air guide assembly rotates, improving the dust removal effect on the dust screen, preventing the dust screen from being blocked, thereby preventing the device from affecting heat dissipation. 2. When the blades are in the closed position, a power flow channel is formed. The airflow passing through the power flow channel can drive the air guide assembly to rotate. There is no need to set up a power mechanism, which simplifies the structure and reduces costs. 3. The blades rotate between the on position and the off position under the action of the air flow to realize the opening and closing of the movable air outlet, which can be achieved by simply controlling the forward and reverse rotation of the motor, with a simple structure and low cost; 4. The dustproof net is equipped with a cooling block, which can not only condense water vapor to absorb dust and improve the dust removal effect, but also cool the gas entering the equipment and improve the heat dissipation effect.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0021] The present application provides a processing device including a fan device capable of directing external air into the device for heat dissipation. The processing device may be a control device, such as a server, computer, or control cabinet; a communications device, such as a switch or large router; or a household appliance, such as an air conditioner outdoor unit, a washing machine, or a refrigerator.

[0022] It should be noted that the function of the fan device is to guide the flow of gas, which can flow into or out of the device. This can be configured based on the device type and needs, and is not limited here. For example, in other embodiments, the fan device can also draw gas from the device or guide external constant-temperature gas to stabilize the internal temperature of the device. The following description uses the example of a fan device used to guide external gas into the device for heat dissipation.

[0023] like Figure 1 and Figure 2 As shown, the processing equipment has a shell 200 , and a mounting opening 210 is opened on the shell 200 . The fan device 100 is installed at the mounting opening 210 to guide external air into the interior of the shell 200 .

[0024] In one embodiment, the fan device 100 includes a mounting block 110, a fan 120, and a dust screen 130. The mounting block 110 is mounted at the mounting opening 210 of the housing 200 and defines a channel 111 having a first end and a second end. The fan 120 is capable of forward and reverse rotation and is disposed at the first end of the channel 111. The dust screen 130 is disposed at the second end of the channel 111. Specifically, the fan 120 is located inside the device, while the dust screen 130 is located outside the device, and both can be connected to the device or the mounting block 110. When the fan 120 rotates forward, it can guide external air into the device through the channel 111, while the dust screen 130 can filter and remove dust from the external air. When the fan 120 rotates reversely, it can blow air toward the dust screen 130 to remove dust adhering to the dust screen 130.

[0025] Furthermore, the fan device 100 also includes an air guide assembly 140, which is disposed within the channel 111 and is configured to rotate about the axial rotation axis of the channel 111. The air guide assembly 140 is capable of forming active air ports 141 and normally open air ports 142 within the channel 111, with the active air ports 141 and normally open air ports 142 being arranged sequentially around the rotation axis. The air guide assembly 140 is configured to open and close the active air ports 141.

[0026] When the fan 120 rotates forward, the active air outlet 141 opens, and the air flow in the channel 111 flows toward the fan 120 through the active air outlet 141 and the normally open air outlet 142, that is, it penetrates into the interior of the device through the active air outlet 141 and the normally open air outlet 142; when the fan 120 rotates reversely, the active air outlet 141 closes, and the air flow in the channel 111 flows toward the dustproof net 130 through the normally open air outlet 142, and the air guide assembly 140 rotates under the action of the air flow to blow off the dust on the dustproof net 130.

[0027] When the fan device 100 is used to dissipate heat from the device, the fan 120 rotates forward, guiding the cold air from the outside to penetrate into the device through the active air vents 141 and the normally open air vents 142. The large flow area ensures that the air intake meets the heat dissipation requirements, and the dust screen 130 filters the outside air. When there is a lot of dust on the dust screen 130, the fan 120 rotates in the reverse direction, the active air vents 141 are closed, and the air flow is blown toward the dust screen 130 through the normally open air vents 142 to blow the dust off the dust screen 130, avoid clogging the dust screen 130, and ensure the heat dissipation effect of the processing equipment. At the same time, when the fan 120 rotates in the reverse direction, since the active air vents 141 are closed, the air flow in the channel 111 is blown toward the dust screen 130 through the normally open air vents 142, reducing the gas flow area, thereby increasing the gas flow rate, and further increasing the impact of the air flow on the dust screen 130, ensuring that the dust on the dust screen 130 is blown off. In addition, the air guide assembly 140 rotates under the action of the airflow, and the normally open air outlet 142 rotates accordingly, thereby increasing the dust removal area of the dustproof net 130, blowing off the dust on the dustproof net 130 as much as possible, and improving the dust removal effect of the dustproof net 130.

[0028] It should be explained that the dust screen 130 is used to filter the air entering the channel 111. The ventilation area on the dust screen 130 through which the air passes will be contaminated with dust, and the area of the ventilation area will not be larger than the flow area of the channel 111. At the same time, during backflow (the fan 120 is reversed), the air guide assembly 140 rotates, and the normally open air port 142 rotates accordingly. Moreover, the normally open air port 142 and the movable air port 141 are arranged in sequence around the rotation axis. Therefore, the rotation of the normally open air port 142 can cause the normally open air port 142 to move along a circular path. Compared with the normally open air port 142 being stationary, the area passed by the rotating normally open air port 142 will be impacted by the airflow, thereby increasing the impact area of the airflow, that is, the airflow blowing towards the dust screen 130 covers the ventilation area, so as to blow off as much dust as possible in the ventilation area, thereby improving the dust removal effect of the dust screen 130.

[0029] In one embodiment, the fan device 100 further includes a cooling block 150, which is disposed on the dustproof net 130 and is used to cool the dustproof net 130 so that water vapor in the air condenses into liquid on the dustproof net 130, and the liquid wets and gathers dust on the dustproof net 130. In this way, during the backflushing process, dust removal can be achieved by blowing off the liquid adhering to the dustproof net 130, further improving the dust removal effect on the dustproof net 130. In addition, when dissipating heat from the device, the cooling block 150 can also cool the airflow passing through the dustproof net 130, thereby further improving the heat dissipation effect on the device. Optionally, the cooling block 150 is a Peltier, with its cold end in contact with the dustproof net 130. Of course, the cooling block 150 can also be other cooling structures, such as a conventional cooling structure including a compressor and a condenser, which is not limited here.

[0030] Furthermore, the dust screen 130 has a cooling area, the ventilation area surrounds the cooling area, and the cooling block 150 is arranged in the cooling area. In this way, the cooling block 150 can not only cool down the ventilation area of the dust screen 130, but also make the ventilation area annular. In combination with the above-mentioned normally open air outlet 142 and the movable opening arranged in sequence around the rotation axis, and the normally open air outlet 142 can rotate around the rotation axis with the air guide assembly 140, it can be determined that the airflow blowing to the dust screen 130 through the normally open air outlet 142 passes through the area of the dust screen 130 and is also annular, so as to blow off the dust on the dust screen 130 as much as possible. Figure 1 In the illustrated embodiment, the cooling area is the area covered by the cooling block 150 , and the ventilation area is the area surrounding the cooling area and corresponding to the channel 111 .

[0031] Furthermore, during the rotation of the air guide assembly 140, the area passed by the normally open air outlet 142 during the rotation corresponds to the ventilation area. In this way, it can be ensured that the faster air flow during the backflush process blows through the entire ventilation area, blowing away the dust in the ventilation area of the dustproof net 130.

[0032] In one embodiment, the dustproof net 130 is made of metal and can be a metal sponge structure with good thermal conductivity. Its surface and structural pores are coated with Teflon coating to reduce surface adhesion and thereby improve the dust removal effect of backblowing.

[0033] See also Figure 3 and Figure 4 In one embodiment, air guide assembly 140 includes a connecting block 143 rotatably disposed within channel 111, with the aforementioned active air vent 141 and normally open air vent 142 formed between connecting block 143 and the inner wall of channel 111. Specifically, channel 111 has a circular cross-section, and a mounting plate 112 is disposed within channel 111. Mounting plate 112 is located in the middle of channel 111 in its cross-section and is fixedly connected to the inner wall of channel 111 via multiple (e.g., four in the figure) connecting arms 113. Mounting block 110 is rotatably connected to mounting plate 112.

[0034] Furthermore, the air guide assembly 140 includes a plurality of blades 144, which are movably connected to the connecting block 143. The movement of the plurality of blades 144 can open and close the movable air port 141. Specifically, when the fan 120 rotates forward, the plurality of blades 144 open the movable air port 141, allowing air from the outside to enter the device through the movable air port 141. When the fan 120 rotates reversely, the plurality of blades 144 close the movable air port 141, thereby allowing air in the channel 111 to flow through the normally open air port 142.

[0035] Specific to Figure 3 In the embodiment shown, the connecting block 143 is columnar and is located in the middle of the channel 111. The connecting block 143 and the inner wall of the channel 111 form an annular gap. The active air outlet 141 and the normally open air outlet 142 are part of the annular gap and are interconnected. The multiple blades 144 can cover the area where the active air outlet 141 is located during the activity, thereby closing the active air outlet 141.

[0036] Furthermore, each blade 144 is capable of rotating between an on position and a off position. When each blade 144 is in the on position, the active air vent 141 is open; and when each blade 144 is in the off position, the active air vent 141 is closed.

[0037] In one embodiment, when each blade 144 is in the closed position, the multiple blades 144 form a power flow channel 145 on the side facing the fan 120. Both ends of the power flow channel 145 extend to the normally open air port 142, and the power flow channel 145 gradually moves away from the fan 120 from one end to the opposite end. When the fan 120 is reversed, all the blades 144 are in the closed position, forming the above-mentioned power flow channel 145. The airflow flows along the power flow channel 145 to the normally open air port 142, and then flows from the normally open air port 142 to the dustproof net 130. Since the power flow channel gradually moves away from the fan 120 from one end to the other end, the airflow flowing through the power flow channel 145 will drive the blades 144 and the connecting block 143 to rotate, thereby realizing the rotation of the normally open air port 142.

[0038] Combine Figure 4 To illustrate, at this point, all blades 144 are in the closed position, and the power channel 145 has a first end 1451 and a second end 1452 opposite each other. Both the first end 1451 and the second end 1452 extend to the normally open air port 142. From the first end 1451 to the second end 1452, the power channel 145 gradually moves away from the fan 120. In other words, the power channel 145 extends in a spiral along the axial direction of the channel 111. Thus, as the airflow flows from the first end 1451 to the second end 1452 and out of the normally open air port 142, the airflow drives the air guide assembly 140 to rotate.

[0039] It can be seen from this that when the equipment needs to be cooled, the air guide assembly 140 in the above embodiment can open the active air outlet 141, and let in air through the active air outlet 141 and the normally open air outlet 142, thereby increasing the air intake flow rate and ensuring the heat dissipation effect; and when the dustproof net 130 needs to be cleaned, all blades 144 are closed, the active air outlet 141 is closed, and the airflow is accelerated through the normally open air outlet 142 to increase the impact on the dustproof net 130. At the same time, the power flow channel 145 formed by the blades 144 can enable the air guide assembly 140 to rotate under the action of the airflow, so that the path area of the rotating normally open air outlet 142 corresponds to the ventilation area of the dustproof net 130, ensuring that the dust in the ventilation area is blown off, thereby improving the dust removal effect.

[0040] As can be seen from the above description, in the above embodiment, blades 144 can completely close active air vents 141. In other embodiments, blades 144 can also partially close active air vents 141, which can also reduce the gas flow area and increase the gas flow rate. Of course, it is preferred that blades 144 completely close active air vents 141.

[0041] The rotation of the blade 144 can be achieved by using the following three embodiments: Example 1 When the fan 120 rotates forward, each blade 144 is able to rotate to the on position under the action of the airflow; when the fan 120 rotates reversely, each blade 144 is able to rotate to the off position under the action of the airflow. Therefore, it can be seen that in this embodiment, the blades 144 are directly rotated between the on and off positions by the wind force, and the rotation is controlled by the forward and reverse rotation of the motor, which simplifies the structure and reduces the cost.

[0042] Example 2 Based on Example 1, the air guide assembly 140 further includes multiple reset members. Each reset member is connected between each blade 144 and the connecting block 143, and the reset member can provide a force to rotate the blade 144 to the closed position or the conducting position. In this embodiment, the addition of reset members ensures that the blade 144 returns to the closed position or the conducting position, thereby improving the operational stability of the air guide assembly 140. The reset member can be a spring or a spring, and the reset member preferably pushes the blade 144 back to the closed position.

[0043] It needs to be explained that, Figure 3 As shown, when blades 144 are in the on position, they face the fan 120 and are parallel to the axial direction of the channel 111. If the fan 120 is reversed, the blades 144 may experience force balance and remain in the on position. Of course, to address this issue, the shape of the blades 144 can be improved to ensure that the blades 144 can be blown to the off position when the fan 120 is reversed, and this is not limited here.

[0044] Example 3 Air guide assembly 140 also includes a drive module, which is mounted on connection block 143 and connected to multiple blades 144 to drive blades 144 to rotate between an on position and a off position. Furthermore, fan device 100 also includes a control module, which is electrically connected to the drive module and fan 120. In this embodiment, the opening and closing of blades 144 are achieved through electronic control, which can improve control accuracy.

[0045] It should be noted that, in order to ensure that the blade 144 rotates between the on position and the off position, a limiting structure may be provided on the inner wall of the channel 111 and / or the connecting block 143 to limit the rotation of the blade 144.

[0046] In order to facilitate understanding of the technical solution of this application, Figures 2 to 4 And Example 1 describes the workflow of the above-mentioned processing equipment: During the operation of the device, the fan 120 rotates forward, and the blades 144 are located in the conduction position under the action of the airflow. The external air passes through the dustproof net 130 and enters the channel 111, and then passes through the active air outlet 141, the normally open air outlet 142 and the fan 120 and enters the interior of the device.

[0047] After the fan 120 rotates forward for a preset time, it switches to the reverse state, and the blades 144 rotate to the closed position under the action of the airflow. After the airflow flows through the power flow channel 145, the normally open air outlet 142 blows toward the dustproof net 130. The air guide component 140 rotates under the action of the airflow, thereby driving the normally open air outlet 142 to rotate, so that the high-speed airflow blown out from the normally open air outlet 142 blows through the entire ventilation area to remove the dust on the ventilation area.

[0048] In summary, the fan device 100 and processing equipment provided by this application have at least the following advantages: 1. When the fan 120 rotates forward to allow air to enter the device, the active air vents 141 and the normally open air vents 142 open, and the dust screen 130 filters the incoming air. When the fan 120 rotates backward, the active air vents 141 close, and air flows through the normally open air vents 142 toward the dust screen 130, increasing the air flow speed. Simultaneously, the air guide assembly 140 rotates, improving the dust removal effect on the dust screen 130 and preventing the dust screen 130 from being clogged, thereby preventing the device from affecting heat dissipation. 2. When the blades 144 are in the closed position, a power flow channel 145 is formed. Airflow passing through the power flow channel 145 can drive the air guide assembly 140 to rotate. No power mechanism is required, which simplifies the structure and reduces costs. 3. The blade 144 rotates between the on position and the off position under the action of the air flow to realize the opening and closing of the movable air outlet 141. This can be realized by simply controlling the forward and reverse rotation of the motor, which has a simple structure and low cost. 4. A cooling block 150 is provided on the dustproof net 130, which can not only condense water vapor to absorb dust and improve the dust removal effect, but also cool the gas entering the device and improve the heat dissipation effect.

[0049] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
