Description

Technical Field

[0001] This disclosure relates to the field of duct dust removal technology, and in particular to a duct dust removal component and electrical equipment. Background Technology

[0002] In related technologies, electrical equipment such as inverters use air cooling for heat dissipation. Specifically, ambient air enters the air duct through the air inlet and is discharged to the outside of the air duct through the air outlet. The air inlet is equipped with a wire mesh, filter cotton or other filter components.

[0003] Air often contains dust, flying insects, and other debris, which can easily adhere to the filter. The filter gradually becomes clogged with debris, which means the air duct is blocked. This results in low air intake efficiency of electrical equipment, affects the heat dissipation performance of electrical equipment, and may even cause the electrical equipment to shut down or be damaged due to overheating.

[0016] In some embodiments, there are two or at least three settling zones. The settling zone adjacent to the air inlet is the front settling zone, and the settling zone adjacent to the air outlet is the rear settling zone. When there are at least three settling zones, the settling zone between the front and rear settling zones is the intermediate settling zone. The outlet is located in the front settling zone. The front and intermediate settling zones are each provided with a first air vent on the side away from the air inlet along the first direction. A second baffle is provided at the first air vent.

[0017] In some embodiments, the first guide plate has a first plate end and a second plate end, the first plate end being connected to the housing; in a first direction, the first plate end is located between the air inlet and the second plate end.

[0018] In some embodiments, a second guide plate is provided at the air inlet, the second guide plate extends from the air inlet toward the first guide plate, and the second guide plate and the first guide plate are spaced apart in a first direction.

[0019] In some embodiments, the second guide plate satisfies at least one of the following: the second guide plate has a third plate end and a fourth plate end, the third plate end is connected to the housing, and in the height direction, the third plate end is located between the bottom end and the fourth plate end; there are at least two second guide plates, and the at least two second guide plates are spaced apart along the height direction.

[0020] In some embodiments, the duct dust removal assembly further includes at least one of a first filter and a second filter; the first filter is disposed at the air outlet, and the second filter is disposed at the air inlet; the filtration level of the second filter is lower than that of the first filter.

[0021] Secondly, this disclosure provides an electrical device, which includes: a housing, a fan, and a dust removal component for air ducts provided in any of the above embodiments; wherein, the housing has a heat dissipation air duct, the dust removal component for air ducts is disposed at the heat dissipation inlet of the heat dissipation air duct, and the air outlet of the dust removal component for air ducts is connected to the heat dissipation inlet; the fan is disposed in the housing.

[0024] In the dust removal assembly provided in this disclosure, after air enters the dust removal duct from the air inlet, the airflow will flow to the vicinity of the first guide plate, which is located between the air inlet and the air outlet. The first guide plate has a first plate end 1 and a second plate end distributed along the height direction. The airflow will change direction after being blocked and guided by the first guide plate. Dust, flying insects and other debris carried in the airflow are difficult to change direction with the mainstream airflow in time due to centrifugal force. The debris is thrown into the settling area, thereby realizing the separation of air and debris, that is, realizing airflow dust removal (airflow impurity removal). This reduces the probability of debris clogging the filter components or other parts of the duct, thereby reducing the probability of debris clogging the duct and improving the air intake efficiency of electrical equipment.

This allows debris in the settling zone to be discharged by opening the outlet through the first baffle, reducing the likelihood of debris flowing towards the outlet and further reducing the chance of debris clogging the duct, thus improving the air intake efficiency of the electrical equipment.

[0066] The terms "parallel" and "perpendicular" used in this disclosure refer to "basically parallel" and "basically perpendicular" in actual operation. "Basically parallel" can be understood as parallelism with a certain degree of error, and similarly, "basically perpendicular" can be understood as perpendicularity with a certain degree of error.

[0067] This disclosure provides a dust removal component and electrical equipment for air ducts to reduce the likelihood of air ducts being blocked by debris and to improve the air intake efficiency of the electrical equipment.

[0068] The electrical equipment provided in the embodiments of this disclosure will be described first with reference to the accompanying drawings.

[0069] like Figure 1 and Figure 2 As shown, the electrical equipment 100 provided in this embodiment includes: a housing 3, a fan 2, and a dust removal assembly 1 for the air duct.

[0070] The enclosure 3 has a heat dissipation duct 34 inside. The fan 2 is used to drive the airflow through the heat dissipation duct 34. The fan 2 is installed in the enclosure 3, and the fan 2 can be located inside or outside the enclosure 3.

[0071] The heat dissipation duct 34 has a heat dissipation inlet 341 and a heat dissipation outlet 342, and the fan 2 is located at the heat dissipation inlet 341, the heat dissipation outlet 342 or other locations.

[0072] The dust removal assembly 1 is located at the heat dissipation inlet 341 of the heat dissipation duct 34. To facilitate the installation of the fan 2 and the dust removal assembly 1, they are installed at different locations within the heat dissipation duct 34. For example, the fan 2 is located at the heat dissipation outlet 342.

[0073] The following description, in conjunction with the attached diagram, details the dust removal component 1 in the air duct.

[0074] like Figure 1 As shown, the dust removal assembly 1 for the air duct provided in this embodiment includes a housing 11, a first baffle 12 and a first guide plate 13.

[0075] The housing 11 has a dust removal duct 01, the height of which is parallel to the height of the housing 11. The dust removal duct 01 has a bottom end 1101 and a top end 1102 along its height. For example, to simplify the structure of the housing 11, the bottom end 1101 of the dust removal duct 01 is the bottom end 1101 of the housing 11, and the top end 1102 of the dust removal duct 01 is the top end 1102 of the housing 11.

[0076] The dust removal duct 01 has an air inlet 011 and an air outlet 012, which are distributed along a first direction perpendicular to the height direction of the dust removal duct 01. It can be understood that the air inlet 011 is used to allow airflow into the dust removal duct 01, and the air outlet 012 is used to allow airflow to exit the dust removal duct 01. Airflow can flow from the air inlet 011 to the air outlet 012.

[0077] The first guide plate 13 is disposed inside the dust removal duct 01. In the first direction, the first guide plate 13 is located between the air inlet 011 and the air outlet 012 of the dust removal duct 01. It can be understood that the air inlet 011, the first guide plate 13 and the air outlet 012 are distributed along the first direction.

[0078] The housing 11 includes multiple housing plates 1107, with an air inlet 011 located on one of the housing plates 1107. For example, the housing plate 1107 containing the air inlet 011 is perpendicular to a first direction. To improve the guiding effect of the first guide plate 13, the projection of the first guide plate 13 onto the housing plate 1107 containing the air inlet 011 overlaps with the area of ​​the housing plate 1107 containing the air inlet 011. For example, the projection of the first guide plate 13 onto the housing plate 1107 containing the air inlet 011 covers the entire air inlet 011 or a portion of the air inlet 011. In some other embodiments, the projection of the first guide plate 13 onto the housing plate 1107 containing the air inlet 011 does not overlap with the area of ​​the housing plate 1107 containing the air inlet 011.

[0079] The first guide plate 13 has a first plate end 1301 and a second plate end 1302, which are distributed along the height direction. In the height direction, the second plate end 1302 is closer to the bottom end 1101 than the first plate end 1301.

[0080] To facilitate the installation of the first guide plate 13, the first plate end 1301 is connected to the housing 11, and the second plate end 1302 is suspended.

[0081] For example, the first plate end 1301 of the first guide plate 13 is connected to the top end 1102 of the dust removal duct 01; or, the first plate end 1301 of the first guide plate 13 is located between the bottom end 1101 and the top end 1102.

[0082] Settling zone 014 is configured to accommodate debris separated from the airflow. It should be noted that settling zone 014 is a dead zone in the air duct. When the airflow flows from air inlet 011 to air outlet 012, the airflow will not reach settling zone 014, and debris will be deposited in settling zone 014.

[0083] In the vertical direction, the settlement zone 014 is farther away from the top 1102 than the first guide plate 13, which can be understood as: the settlement zone 014 is farther away from the top 1102 than the second plate end 1302.

[0084] In the first direction, at least a portion of the settling zone 014 is located between the air inlet 011 and the first guide plate 13. For example, in the first direction, a portion of the settling zone 014 is located between the air inlet 011 and the first guide plate 13, in which case the projection of the second plate end 1302 along the height direction and the projection of the settling zone 014 along the height direction overlap; or, in the first direction, the settling zone 014 is located between the air inlet 011 and the first guide plate 13.

[0085] After air enters the dust removal duct 01 through the air inlet 011, the airflow is diverted near the first guide plate 13, which is located between the air inlet 011 and the air outlet 012. The first guide plate 13 has a first plate end 1301 and a second plate end 1302 distributed along its height. The airflow is blocked and guided by the first guide plate 13, causing it to change direction. Dust, flying insects, and other debris carried in the airflow are difficult to change direction with the mainstream airflow in time due to centrifugal force, and the debris is thrown towards the settling zone 014, thus achieving separation of air and debris, i.e., achieving airflow dust removal (airflow impurity removal). Because the debris in the airflow is separated from the air under the action of centrifugal force, compared with related technologies that filter debris in the airflow through filter components, the separation effect of debris and air is effectively improved, thus providing an effective airflow dust removal effect.

[0086] It should be noted that the area where the airflow turns at the bottom side of the second plate end 1302 can be called the turning zone 013. The bottom side of the second plate end 1302 refers to the side of the second plate end 1302 closest to the bottom end 1101. The turning zone 013 and the settling zone 014 are distributed along the height direction, and in the height direction, the settling zone 014 is closer to the bottom end 1101 than the turning zone 013. The radius of curvature of the airflow turning at the turning zone 013, and the distance between the second plate end 1302 of the first guide plate 13 and the bottom end 1101 of the dust removal duct 01, can be designed according to actual conditions to ensure that during the turning process, debris moves towards the settling zone 014 under the action of centrifugal force, while the airflow turning has a small impact on wind resistance.

[0087] The volume of the settling zone 014 can be designed according to the operating environment, operating cycle, air intake, and debris concentration of the electrical equipment 100. For example, the volume of the settling zone 014 can be slightly larger than the volume of debris expected to be deposited in a single operating cycle of the electrical equipment 100 to prevent debris from overflowing or clogging the dust removal duct 01. This embodiment of the present disclosure does not limit the size of the settling zone 014, as long as it can meet the requirements for debris deposition and discharge.

[0088] The outlet 1103 of the dust removal duct 01 is located in the settling zone 014. The outlet 1103 is used to discharge debris in the settling zone 014. The first baffle 12 is disposed on the housing 11. The first baffle 12 has a first state of closing the outlet 1103 and a second state of opening the outlet 1103.

[0089] When airflow flows from the air inlet 011 to the air outlet 012, the first baffle 12 can be in its first state, with the outlet 1103 closed. Airflow enters the dust removal duct 01 from the air inlet 011, but does not enter the dust removal duct 01 from the outlet 1103, thus preventing debris from entering the dust removal duct 01 from the outlet 1103. When it is necessary to clean debris from the settling zone 014, the first baffle 12 can be in its second state, with the outlet 1103 open, allowing debris in the settling zone 014 to be removed from the dust removal duct 01 through the outlet 1103. This removes debris from the settling zone 014, reducing the likelihood of debris flowing from the settling zone 014 to the air outlet 012.

[0090] It should be noted that the first baffle 12 can be in the first state when there is no need to clean the debris in the settling zone 014, and is not limited to the case where the airflow flows from the air inlet 011 to the air outlet 012.

[0091] As can be seen from the above, the duct dust removal component 1 provided in this embodiment of the present disclosure achieves dust removal of airflow, reducing the probability of debris clogging the filter components or other parts of the duct, that is, reducing the probability of debris clogging the duct (dust removal duct 01 and heat dissipation duct 34), thereby improving the air intake efficiency of the electrical equipment; moreover, the debris deposited in the settling zone 014 can be discharged through the discharge port 1103, which can reduce the probability of debris flowing to the air outlet 012, thereby further reducing the probability of debris clogging the duct and further improving the air intake efficiency of the electrical equipment 100.

[0092] Since the dust removal component 1 in the duct improves the air intake efficiency of the electrical equipment 100, the dust removal component 1 in the duct improves the heat dissipation performance of the electrical equipment 100, reduces the probability of the electrical equipment 100 shutting down or being damaged due to overheating, and correspondingly reduces the maintenance cost of manual maintenance of the electrical equipment 100 and shortens the downtime of the electrical equipment 100.

[0093] In the dust removal assembly 1 provided in this embodiment, the outlet 1103 is opened by the first baffle 12, which can remove the debris deposited in the settling zone 014. The debris in the settling zone 014 can be removed as needed, which can reduce the cost of manual maintenance of electrical equipment. Compared with related technologies for removing debris from filter components, it can effectively improve the removal efficiency of debris.

[0094] In some embodiments, the first baffle 12 is detachably disposed on the housing 11. For example, the first baffle 12 is detachably disposed on the housing 11 via a threaded connection, a magnetic structure, or a snap-fit ​​structure. When it is necessary to close the discharge port 1103, the first baffle 12 is connected to the housing 11 and closes the discharge port 1103, placing the first baffle 12 in a first state. When it is necessary to open the discharge port 1103, the first baffle 12 can be detached from the housing 11, separating the first baffle 12 from the housing 11, thereby opening the discharge port 1103 and placing the first baffle 12 in a second state. In this embodiment, the connection structure between the first baffle 12 and the housing 11 is simple, facilitating manual maintenance and cleaning of debris in the settling zone 014.

[0095] In some other embodiments, the first baffle 12 is movably or deformably disposed on the housing 11 to switch between the first state and the second state. The movement of the first baffle 12 can be rotation, sliding, or other movement that can open and close the outlet 1103, which is not limited in this disclosure. The deformation of the first baffle 12 can be elastic deformation or other deformation that can open and close the outlet 1103, which is not limited in this disclosure.

[0096] like Figure 1As shown, in some embodiments, the outlet 1103 is located on the side of the settling zone 014 near the air inlet 011; the first baffle 12 is configured to be in a first state when the airflow flows from the air inlet 011 to the air outlet 012; as Figure 2 As shown, the second state is when the airflow flows from the air outlet 012 to the exhaust outlet 1103. It should be noted that the airflow from the air inlet 011 to the air outlet 012 can be called the forward airflow, and the airflow from the air outlet 012 to the exhaust outlet 1103 can be called the reverse airflow.

[0097] like Figure 1 As shown, outside air enters the dust removal duct 01 through the air inlet 011 and exits the dust removal duct 01 through the air outlet 012. In this case, the first baffle 12 is in the first state, and the first baffle 12 closes the outlet 1103. Figure 1 The exhaust outlet 1103 is not displayed to ensure normal air intake of the dust removal duct 01 and to prevent outside air or debris from abnormally entering the dust removal duct 01 through the exhaust outlet 1103. Figure 2 As shown, the airflow flows from the outlet 012 to the discharge outlet 1103. The first baffle 12 is in the second state, and the discharge outlet 1103 is open. During the process of the airflow flowing from the outlet 012 to the discharge outlet 1103, the airflow passes through the settling zone 014, carrying away the debris in the settling zone 014 and discharging it through the discharge outlet 1103. This allows the dust, flying insects, and other debris deposited in the settling zone 014 to be discharged from the discharge outlet 1103 under the action of the reverse airflow. In this way, the reverse airflow can be used to achieve automatic dust removal of the duct dust removal component 1, reducing the workload of maintenance personnel and the frequency of manual maintenance, which is conducive to reducing the maintenance cost of electrical equipment.

[0098] In some embodiments, a fan 2 is provided on the air outlet side of the air outlet 012, and the duct dust removal component 1 can be used in conjunction with the fan 2. Specifically, when the fan 2 rotates forward, airflow can flow from the air inlet 011 to the air outlet 012, which can be understood as: when the fan 2 rotates forward, airflow flows from the air inlet 011 to the air outlet 012; when the fan 2 rotates in reverse, airflow can flow from the air outlet 012 to the exhaust outlet 1103, which can be understood as: when the fan 2 rotates in reverse, airflow flows from the air outlet 012 to the exhaust outlet 1103. Alternatively, when the fan 2 rotates in reverse, airflow can flow from the air inlet 011 to the air outlet 012; when the fan 2 rotates forward, airflow can flow from the air outlet 012 to the exhaust outlet 1103.

[0099] Fan 2 can reverse when the electrical equipment is shut down or during a set period of time (such as at night) to automatically remove deposited debris, which can effectively reduce the maintenance cost of the electrical equipment.

[0100] In some other embodiments, fans can also be installed at other locations of the dust removal duct 01, and are not limited to the air outlet side of the air outlet 012. For example, fans are installed on both the air outlet side of the air outlet 012 and the air outlet side of the exhaust port 1103.

[0101] The first baffle 12 is in a first state when the airflow flows from the air inlet 011 to the air outlet 012, and in a second state when the airflow flows from the air outlet 012 to the exhaust outlet 1103. This can be achieved through the following embodiments.

[0102] like Figure 3a As shown, in some embodiments, the first end 1201 of the first baffle 12 is connected to the housing 11, and the second end 1202 of the first baffle 12 is detachably attached to the housing 11; the first baffle 12 is an elastic plate 12a. Figure 3b As shown, the elastic plate 12a is configured to deform and separate from the housing 11 under the action of airflow from the outlet 012 to the outlet 1103, thereby opening the outlet 1103. In the absence of airflow from the outlet 012 to the outlet 1103, for example, when airflow flows from the inlet 011 to the outlet 012, the elastic plate 12a can return to its original shape and close the outlet 1103 by its own elastic restoring force.

[0103] For example, such as Figure 3a As shown in Figure b, the first baffle 12 in the first state is in its original state, that is, the first baffle 12 in the first state has not deformed; as shown in Figure b, the first baffle 12 in the second state is in a deformed state, that is, the first baffle 12 in the second state has deformed.

[0104] The first end 1201 of the first baffle 12 can be fixed to the housing 11 or hinged to the housing 11, depending on the actual situation. This embodiment does not limit this.

[0105] The second end 1202 of the first baffle 12 and the housing 11 can be separably bonded through direct contact; alternatively, the second end 1202 of the first baffle 12 and the housing 11 can be indirectly bonded through a magnetic attraction structure to achieve separable bonding. This disclosure does not limit the scope of the embodiments.

[0106] The opening pressure threshold of the elastic plate 12a can be set according to the air pressure flowing from the air outlet 012 to the exhaust outlet 1103, for example, based on the reverse air pressure when the fan 2 reverses, to ensure that the reverse airflow reaches the set air pressure to deform the elastic plate 12a and open the exhaust outlet 1103. In addition, the opening pressure threshold of the elastic plate 12a also needs to ensure that the elastic plate 12a will not deform erroneously when the airflow flows from the air inlet 011 to the air outlet 012 or when the external disturbance is small, so as to avoid the exhaust outlet 1103 from opening accidentally.

[0107] In the above embodiments, the connection structure between the first baffle 12 and the housing 11 can be simplified by opening the outlet 1103 through the elastic deformation of the elastic plate 12a; it also enables the elastic plate 12a to automatically open the outlet 1103 under the action of the reverse airflow, thereby facilitating the discharge of debris in the settling zone 014; moreover, the elastic plate 12a can automatically reset, which facilitates the switching of the duct dust removal component 1 between two states (the state where the outlet 1103 is open and the state where the outlet 1103 is closed).

[0108] In the above embodiments, the outlet 1103 is opened by the elastic deformation of the elastic plate 12a, and the elastic plate 12a can be automatically reset to close the outlet 1103 without additional energy consumption, which helps to reduce the usage cost of the entire duct dust removal assembly 1.

[0109] like Figure 4a As shown, in some embodiments, the first end 1201 of the first baffle 12 is rotatably disposed on the housing 11, and the second end 1202 of the first baffle 12 is separably attached to the housing 11. The rotation axis of the first baffle 12 can be parallel to the second direction, and both the first direction and the height direction of the housing 11 are perpendicular to the second direction; alternatively, the rotation axis of the first baffle 12 can also have an angle with the second direction, as long as it allows the first baffle 12 to open and close the outlet 1103 during rotation.

[0110] like Figure 4b As shown, the duct dust removal assembly 1 may further include a first drive component 15, which is convexly connected to a first baffle 12. The first drive component 15 is configured to drive the first baffle 12 to rotate and separate from the housing 11 when airflow flows from the outlet 012 to the discharge outlet 1103, thereby opening the discharge outlet 1103. For example, as... Figure 4a As shown, when airflow flows from outlet 012 to outlet 1103, the first driving component 15 drives the first baffle 12 to rotate counterclockwise to open outlet 1103. It should be noted that... Figure 4a The discharge outlet 1103 is not shown in the data.

[0111] The first drive component 15 can be a motor, a rotary cylinder, or other drive components. For example... Figure 4c As shown, after the first baffle 12 rotates to a set angle, the outlet 1103 opens. The specific value of the set angle is designed according to the actual situation, and this embodiment does not limit it.

[0112] In the above embodiment, the first baffle 12 is rotatably mounted on the housing 11 via a rotating shaft 16. The rotating shaft 16 is rotatably mounted on the housing 11, and the first baffle 12 is fixed to the rotating shaft 16. The output shaft of the first drive component 15 is connected to the rotating shaft 16 in a transmission manner. When the fan 2 reverses, the first drive component 15 drives the rotating shaft 16 to rotate, thereby causing the first baffle 12 to rotate and opening the outlet 1103.

[0113] In the above embodiments, the first baffle 12 can be a lightweight structural component, for example, the mass of the first baffle 12 is less than a set mass, so that the first driving component 15 can drive the first baffle 12 to rotate.

[0114] As mentioned above, a fan 2 is installed on the air outlet side of the air outlet 012. The fan 2 rotates forward to allow airflow from the air inlet 011 to the air outlet 012; the fan 2 rotates in reverse to allow airflow from the air outlet 012 to the discharge outlet 1103. Based on this, in order to enable the first drive component 15 to automatically drive the first baffle 12 to rotate, the first drive component 15 can be electrically connected to the fan 2. The first drive component 15 is configured to receive the reverse rotation signal of the fan 2, and drive the first baffle 12 to rotate and separate from the housing 11 according to the reverse rotation signal of the fan 2, so as to open the discharge outlet 1103. In this way, when the fan 2 rotates in reverse, the first drive component 15 automatically drives the first baffle 12 to rotate, realizing the linkage between the first drive component 15 and the fan 2, so as to facilitate the discharge of debris in the settling zone 014.

[0115] In some other embodiments, the duct dust removal assembly 1 may also include a pressure sensor for detecting the airflow pressure at the settling zone 014. The pressure sensor is electrically connected to the first drive component 15. When the airflow pressure detected by the pressure sensor is greater than a set pressure value, the first drive component 15 drives the first baffle 12 to rotate to open the outlet 1103.

[0116] To facilitate the reset of the first baffle 12, the first drive component 15 is configured to drive the first baffle 12 to rotate and fit against the housing 11 when the airflow flows from the air inlet 011 to the air outlet 012, so as to close the outlet 1103.

[0117] For example, such as Figure 4c As shown, the first driving component 15 drives the first baffle 12 to rotate clockwise to close the outlet 1103.

[0118] For example, the first drive component 15 may be electrically connected to the fan 2 to receive the forward rotation signal of the fan 2; or, the first drive component 15 may know that the fan 2 is rotating forward based on the detection value of the pressure sensor.

[0119] In an embodiment where the first baffle 12 is rotatably disposed on the housing 11, the first baffle 12 can rotate under the action of a reverse airflow. Specifically, the first baffle 12 is configured to rotate under the action of a reverse airflow and separate from the housing 11 to open the outlet 1103.

[0120] like Figure 5a and Figure 5b In some embodiments, the duct dust removal assembly 1 further includes a support 17, a lever 18, and a load 19. The support 17 is disposed on the housing 11 and provides a fulcrum 1701; the lever 18 is rotatably disposed on the support 17 about the fulcrum 1701; the lever 18 has a first rod end 1801 and a second rod end 1802; along the length direction of the lever 18, the fulcrum 1701 is located between the first rod end 1801 and the second rod end 1802; the load 19 is disposed on the first rod end 1801, and a first baffle 12 is disposed on the second rod end 1802, such that the first baffle 12 is rotatably disposed on the housing 11 via the lever 18 and the support 17.

[0121] With the first baffle 12 in its first state, the lever 18 is in equilibrium. When airflow flows from the outlet 012 to the discharge outlet 1103, the reverse airflow acts on the first baffle 12, causing the lever 18 to rotate around the fulcrum 1701, for example, as... Figure 5a As shown, lever 18 rotates counterclockwise around fulcrum 1701; the rotating lever 18 drives the first baffle 12 to rotate, thereby opening the outlet 1103. After the reverse airflow weakens or disappears, under the action of load 19, lever 18 rotates around fulcrum 1701 to reset the first baffle 12 and close the outlet 1103, for example, as... Figure 5b As shown, under the action of load 19, lever 18 rotates clockwise around fulcrum 1701.

[0122] In the above embodiment, the first baffle 12 automatically opens the outlet 1103 under the action of the reverse airflow, thereby facilitating the discharge of debris in the settling zone 014; moreover, the first baffle 12 can automatically reset, facilitating the switching of the duct dust removal component 1 between two states (the state where the outlet 1103 is open and the state where the outlet 1103 is closed).

[0123] In the above embodiments, the first baffle 12 automatically opens the outlet 1103 under the action of the reverse airflow, and the first baffle 12 can automatically reset to close the outlet 1103 without additional energy consumption, which helps to reduce the usage cost of the entire duct dust removal assembly 1.

[0124] The distance between the center of gravity of the load 19 and the fulcrum 1701 along the length of the lever 18, and the distance between the center of gravity of the first baffle 12 and the fulcrum 1701 along the length of the lever 18, are designed according to actual conditions. For example, the distance between the center of gravity of the load 19 and the fulcrum 1701 along the length of the lever 18 is greater than the distance between the center of gravity of the first baffle 12 and the fulcrum 1701 along the length of the lever 18; or, the distance between the center of gravity of the load 19 and the fulcrum 1701 along the length of the lever 18 is equal to the distance between the center of gravity of the first baffle 12 and the fulcrum 1701 along the length of the lever 18; or, in order to facilitate the rotation of the first baffle 12 under the action of the reverse airflow, the distance between the center of gravity of the load 19 and the fulcrum 1701 along the length of the lever 18 is less than the distance between the center of gravity of the first baffle 12 and the fulcrum 1701 along the length of the lever 18.

[0125] In embodiments where the first baffle 12 is rotatably disposed on the housing 11, the first baffle 12 can also be rotated under the action of reverse airflow through other structures. For example... Figure 6a As shown, in some embodiments, the duct dust removal assembly 1 further includes an elastic element 110, one end of which is connected to the housing 11, and the other end of which is connected to the first baffle 12. When the first baffle 12 is in a first state, the elastic element 110 is in its original length state; when the first baffle 12 is in a second state, the elastic element 110 is in a deformed state.

[0126] In the above embodiments, when the airflow flows from the outlet 012 to the discharge outlet 1103, the reverse airflow acts on the first baffle 12. The force of the reverse airflow acting on the first baffle 12 overcomes the elastic force of the elastic member 110, causing the first baffle 12 to rotate. For example, as... Figure 6a As shown, the first baffle 12 rotates counterclockwise to open the outlet 1103, i.e., the first baffle 12 is in the second state; after the reverse airflow weakens or disappears, the elastic element 110 provides a restoring force, which drives the first baffle 12 to rotate, for example, the first baffle 12 rotates clockwise to close the outlet 1103, i.e., the first baffle 12 returns to the first state.

[0127] In the above embodiments, opening the outlet 1103 by reverse airflow simplifies the connection structure between the first baffle 12 and the housing 11; at the same time, it enables the first baffle 12 to automatically open the outlet 1103 under the action of reverse airflow, thereby facilitating the discharge of debris in the settling zone 014; moreover, the elastic element 110 can automatically reset the first baffle 12, facilitating the switching of the duct dust removal assembly 1 between two states (the state where the outlet 1103 is open and the state where the outlet 1103 is closed).

[0128] In the above embodiments, the first baffle 12 automatically opens the outlet 1103 under the action of the reverse airflow, and the first baffle 12 can automatically reset to close the outlet 1103 without additional energy consumption, which helps to reduce the usage cost of the entire duct dust removal assembly 1.

[0129] In the above embodiments, the first baffle 12 can be a lightweight structural component, for example, the mass of the first baffle 12 is less than a set mass, so that the first baffle 12 can rotate under the action of the reverse airflow.

[0130] like Figure 6a As shown, the elastic element 110 can be located within the housing 11. Alternatively, as... Figure 6b As shown, the elastic element 110 can be located outside the housing 11. In this case, a bracket 1106 is provided on the outside of the housing 11. One end of the elastic element 110 is connected to the first baffle 12, and the other end of the elastic element 110 is connected to the bracket 1106. The specific structure of the bracket 1106 is designed according to the actual situation, and this embodiment does not limit it.

[0131] In an embodiment where the first end 1201 of the first baffle 12 is connected to the housing 11, and the second end 1202 and the housing 11 are separable and fit together, such as Figure 6b As shown, in the first direction, the first end 1201 of the first baffle 12 is farther away from the air inlet 011 than the second end 1202; and in the height direction of the housing 11, the first end 1201 of the first baffle 12 is closer to the bottom end 1101 of the housing 11 than the second end 1202. Thus, when debris is deposited on the first baffle 12, the debris can move towards the outlet 1103 under the action of gravity, which is beneficial for debris deposition. Moreover, in the height direction of the housing 11, the first end 1201 of the first baffle 12 is closer to the bottom end 1101 of the housing 11 than the second end 1202. This ensures that the first baffle 12 is in the first state when the airflow flows from the air inlet 011 to the air outlet 012, reducing the probability of the first baffle 12 accidentally rotating when the airflow flows from the air inlet 011 to the air outlet 012, thereby reducing the probability of the outlet 1103 accidentally opening.

[0132] like Figure 7a and Figure 7b As shown, in some embodiments, the first baffle 12 is slidably disposed on the housing 11; the air duct dust removal assembly 1 may also include a second drive component 114, which is connected to the first baffle 12 in a transmission manner; the second drive component 114 is configured to drive the first baffle 12 to move and separate from the housing 11 when the airflow flows from the air outlet 012 to the outlet 1103, so as to open the outlet 1103.

[0133] like Figure 7aAs shown, the first baffle 12 is in the first state; as Figure 7b As shown, the first baffle 12 is in the second state.

[0134] The sliding direction of the first baffle 12 is parallel to the plane in which the first baffle 12 is located. For example, as Figure 7a As shown, the sliding direction of the first baffle 12 is parallel to the second direction; or, the sliding direction of the first baffle 12 can be parallel to the first direction; or, the sliding direction of the first baffle 12 is inclined to the first direction, and the sliding direction of the first baffle 12 is inclined to the second direction, as long as the first baffle 12 achieves the opening and closing of the outlet 1103 by sliding.

[0135] The above describes an embodiment in which "the first baffle 12 is in a first state when the airflow flows from the air inlet 011 to the air outlet 012, and in a second state when the airflow flows from the air outlet 012 to the exhaust outlet 1103". The following describes other structures of the dust removal duct 01.

[0136] To facilitate the settling and discharge of debris, the surface roughness of the inner wall of the dust removal duct 01 in the settling zone 014 can be less than a set value. The smaller the surface roughness, the less likely dust, flying insects, and other debris will adhere to the inner wall of the settling zone 014, allowing debris to move more smoothly to the bottom of the settling zone 014 and to be discharged more smoothly from the settling zone 014, thereby improving the dust removal effect.

[0137] The inner wall of the dust removal duct 01 in the settling zone 014 can have a high-smoothness layer. The surface roughness of the high-smoothness layer can be less than a set value. The high-smoothness layer can be an anodized aluminum layer, an electrophoretic coating, or other coatings. Alternatively, the inner wall of the dust removal duct 01 in the settling zone 014 can also be a mirror-finished stainless steel surface. In this way, by setting a high-smoothness layer or a mirror-finished stainless steel surface, the surface roughness of the inner wall of the dust removal duct 01 in the settling zone 014 can be less than a set value.

[0138] like Figure 8 As shown, along the height direction of the shell 11, the settling zone 014 has a top 0141 and a bottom 0142. Along the height direction of the shell 11, the top 0141 is closer to the first guide plate 13 than the bottom 0142, and the settling zone 014 gradually expands from the bottom 0142 to the top 0141. It can be understood that the upper space of the settling zone 014 is larger, and the lower space is smaller. This facilitates the entry of debris into the settling zone 014 and facilitates the deposition of debris at the bottom 0142, thus enhancing the deposition effect.

[0139] In some other embodiments, the settling zone 014 gradually narrows from the bottom 0142 to the top 0141; or, the settling zone 014 has a uniform cross-sectional structure from the bottom 0142 to the top 0141. It is understood that the cross-sectional area of ​​the settling zone 014 does not change from the bottom 0142 to the top 0141, and the cross-section of the settling zone 014 is perpendicular to the height direction of the shell 11.

[0140] In this embodiment, the specific shape and structure of the settlement zone 014 are designed according to the actual situation, and this embodiment does not limit them.

[0141] like Figure 8 As shown above, the first guide plate 13 has a first plate end 1301 and a second plate end 1302. In some embodiments, in a first direction, the first plate end 1301 is located between the air inlet 011 and the second plate end 1302. In this way, the first guide plate 13 extends obliquely from the top end 1102 of the housing 11 to the bottom end 1101 and in a direction away from the air inlet 011, which is conducive to the airflow being turned by the action of the first guide plate 13, thereby facilitating the flow of impurities in the airflow to the settling zone 014 under the action of centrifugal force.

[0142] When the angle θ between the first guide plate 13 and the first direction is large, the airflow changes direction more significantly, and the inertial separation effect on debris is more pronounced, which is beneficial to improving separation efficiency. When the angle θ between the first guide plate 13 and the first direction is small, the airflow resistance is relatively small, which is beneficial to reducing duct pressure loss. To improve the guiding effect of the first guide plate 13, the angle θ between the first guide plate 13 and the first direction can be in the range of 60°-90°.

[0143] For example, such as Figure 8 As shown, the angle θ between the first guide plate 13 and the first direction is 60°; or, as... Figure 9 As shown, the angle θ between the first guide plate 13 and the first direction is a right angle, that is, the angle θ is 90°.

[0144] In other examples, the numerical range of the angle θ between the first guide plate 13 and the first direction can also be other.

[0145] like Figure 10 As shown, in some other embodiments, in the first direction, the second plate end 1302 is located between the air inlet 011 and the first plate end 1301. Thus, the first guide plate 13 extends obliquely from the top end 1102 of the housing 11 to the bottom end 1101 and toward the air inlet 011.

[0146] like Figure 8As shown, to further improve the airflow guiding effect, a second guide plate 14 can be provided at the air inlet 011. The second guide plate 14 extends from the air inlet 011 towards the first guide plate 13, and the second guide plate 14 and the first guide plate 13 are spaced apart in the first direction. In this way, the second guide plate 14 can rectify and guide the airflow in the initial stage of the airflow entering the dust removal duct 01, so that the airflow enters the vicinity of the first guide plate 13 at a more suitable angle, thereby improving the stability of the airflow turning and the efficiency of debris separation.

[0147] The second guide plate 14 has a third plate end 1401 and a fourth plate end 1402. The third plate end 1401 is connected to the housing 11. In the height direction of the housing 11, the third plate end 1401 can be located between the bottom end 1101 and the fourth plate end 1402. In this way, the second guide plate 14 guides airflow to the first guide plate 13 and also to the top end 1102 of the housing 11, so that a smoother airflow guiding path is formed between the second guide plate 14 and the first guide plate 13, which is beneficial to guiding the airflow to the first guide plate 13.

[0148] In this embodiment of the disclosure, there is one second guide plate 14; or, as shown below. Figure 10 As shown, there are at least two second guide plates 14, and the at least two second guide plates 14 are distributed at intervals along the height direction. In this way, multiple second guide plates 14 can guide the airflow in the height direction, making the airflow distribution in the dust removal duct 01 more uniform, which can reduce the adverse effects of local high-speed airflow or local backflow on the dust removal effect; it also helps to enhance the separation effect of air and debris.

[0149] In some embodiments, the included angle β between the second guide plate 14 and the height direction can range from 45° to 90°. For example, Figure 8 As shown, the angle β between the second guide plate 14 and the height direction is 45°; or, as... Figure 10 As shown, the angle β between the second guide plate 14 and the height direction is 90°.

[0150] In other embodiments, the angle β between the second guide plate 14 and the height direction can be other values, and is not limited to the embodiments described above.

[0151] like Figure 10As shown, in some embodiments, the duct dust removal assembly 1 further includes a first filter element 112 and a second filter element 113. The first filter element 112 is disposed at the air outlet 012, and the second filter element 113 is disposed at the air inlet 011. The filtration level of the second filter element 113 is lower than that of the first filter element 112. Thus, the second filter element 113 can act as a coarse filter to block larger particles or flying insects; the settling zone 014 in the duct dust removal assembly 1 is used to separate and collect some dust and debris; the first filter element 112 can act as a fine filter to further filter smaller particles. Since a large amount of debris is intercepted or separated by the second filter element 113 and the settling zone 014 before entering the first filter element 112, the probability of the first filter element 112 becoming clogged is reduced, thereby extending the maintenance cycle.

[0152] In some other embodiments, the duct dust removal assembly 1 may also include a first filter element 112 or a second filter element 113, and is not limited to the above embodiments.

[0153] In an embodiment where the duct dust removal assembly 1 includes a second filter element 113, since dust removal is completed before the second filter element 113, the probability of the second filter element 113 being clogged by debris can be reduced, thereby extending the service life of the second filter element 113; and the maintenance frequency of the second filter element 113 can also be reduced.

[0154] like Figure 1 and Figure 2 As shown, in some embodiments, the first guide plate 13 and the settling area 014 in the dust removal assembly 1 are both one. In this case, a turning area 013 and a settling area 014 are formed inside the dust removal duct 01, which makes the structure of the dust removal assembly 1 simpler and the dust removal assembly 1 suitable for scenarios with low impurity concentration or limited installation space.

[0155] In some other embodiments, there are at least two first guide plates 13, and the at least two first guide plates 13 are distributed at intervals along a first direction; there are at least two settlement zones 014, and the at least two settlement zones 014 are distributed at intervals along the first direction. The turning zone 013 and the settlement zone 014 correspond one-to-one.

[0156] For example, such as Figure 11a and Figure 11b As shown, there are two of each: the first guide plate 13, the turning zone 013, and the settlement zone 014; or, as... Figure 12a and Figure 12b As shown, there are three of each of the first guide plate 13, the turning zone 013, and the settling zone 014; or, there are at least four of each of the first guide plate 13, the turning zone 013, and the settling zone 014.

[0157] In the above embodiments, the airflow can turn multiple times within the dust removal duct 01, and debris can settle step by step in multiple settling zones 014, which is beneficial to improving the dust removal efficiency of the duct dust removal component 1.

[0158] For ease of subsequent description, when there are at least two settlement zones 014, the settlement zone 014 adjacent to the air inlet 011 is the front settlement zone 014a, and the settlement zone 014 adjacent to the air outlet 012 is the rear settlement zone 014b. When there are at least three settlement zones 014, the settlement zone 014 located between the front settlement zone 014a and the rear settlement zone 014b is the intermediate settlement zone 014c.

[0159] In an embodiment where the first baffle 12 is in the first state when the airflow flows from the air inlet 011 to the air outlet 012, and in the second state when the airflow flows from the air outlet 012 to the discharge outlet 1103, in order to facilitate the discharge of debris in each settling zone 014, there are two settling zones 014. The discharge outlet 1103 is located in the front settling zone 014a. A first air vent 1104 is provided on the side of the front settling zone 014a away from the air inlet 011 along the first direction. A second baffle 111 is provided at the first air vent 1104. The second baffle 111 has a third state of closing the first air vent 1104 and a fourth state of opening the first air vent 1104. A second air vent 1105 is provided on the side of the rear settling zone 014b close to the air inlet 011 along the first direction. The front settling zone 014a and the rear settling zone 014b are connected through the first air vent 1104 and the second air vent 1105.

[0160] In an embodiment where the first baffle 12 is in the first state when the airflow flows from the air inlet 011 to the air outlet 012, and in the second state when the airflow flows from the air outlet 012 to the discharge outlet 1103, in order to facilitate the discharge of debris in each settling zone 014, there are at least three settling zones 014. The discharge outlet 1103 is located in the front settling zone 014a. The front settling zone 014a and the middle settling zone 014c are respectively located away from the air inlet along the first direction. A first air vent 1104 is provided on one side of 011, and a second baffle 111 is provided at the first air vent 1104. The second baffle 111 has a third state of closing the first air vent 1104 and a fourth state of opening the first air vent 1104. The rear settling zone 014b and the intermediate settling zone 014c are respectively provided with a second air vent 1105 on the side of the air inlet 011 along the first direction. The two adjacent settling zones 014 are connected through the first air vent 1104 and the second air vent 1105.

[0161] It should be noted that the housing 11 is provided with a channel that connects the first air vent 1104 of one settling zone 014 and the second air vent 1105 of another settling zone 014.

[0162] For example, such as Figure 11a and Figure 11b As shown, there are two settlement zones 014: one is the front settlement zone 014a, and the other is the rear settlement zone 014b. Figure 11a As shown, when the airflow flows from the air inlet 011 to the air outlet 012, the airflow passes through the dust removal duct 01 and undergoes two turns. Correspondingly, the impurities in the airflow settle in two settling zones 014 in stages. Specifically, some of the impurities in the airflow settle in the front settling zone 014a, and some of the impurities in the airflow settle in the rear settling zone 014b; as Figure 11b As shown, when the airflow flows from the outlet 012 to the discharge outlet 1103, the reverse airflow flows through the outlet 012 and the rear settling zone 014b, then through the second air outlet 1105 of the rear settling zone 014b and the first air outlet 1104 of the front settling zone 014a, and finally exits through the discharge outlet 1103 of the front settling zone 014a. During its flow, the reverse airflow carries away debris from the rear settling zone 014b and the front settling zone 014a, thus discharging the debris.

[0163] For example, such as Figure 12a and Figure 12b As shown, there are three settlement zones 014: one is the front settlement zone 014a, one is the middle settlement zone 014c, and the other is the rear settlement zone 014b. Figure 12a As shown, when the airflow flows from the air inlet 011 to the air outlet 012, the airflow passes through the dust removal duct 01 and undergoes three turns. Correspondingly, the impurities in the airflow settle in three settling zones 014 in stages. Specifically, some impurities in the airflow settle in the front settling zone 014a, some impurities in the airflow settle in the middle settling zone 014c, and some impurities in the airflow settle in the rear settling zone 014b; as shown... Figure 12b As shown, when the airflow flows from the outlet 012 to the discharge outlet 1103, the reverse airflow flows through the outlet 012 and the rear settling zone 014b, then through the second air outlet 1105 of the rear settling zone 014b and the first air outlet 1104 of the intermediate settling zone 014c, entering the intermediate settling zone 014c, then through the first air outlet 1104 of the intermediate settling zone 014c, entering the front settling zone 014a, and finally discharging through the discharge outlet 1103 of the front settling zone 014a. During its flow, the reverse airflow carries away debris from the rear settling zone 014b, the intermediate settling zone 014c, and the front settling zone 014a, thus discharging the debris.

[0164] It should be noted that both the second air vent 1105 and the first air vent 1104 are capable of allowing debris to pass through. The specific size of the second air vent 1105 and the first air vent 1104 is designed according to actual conditions, and this embodiment does not limit this.

[0165] In the above embodiment, the discharge port 1103 is located in the front settling zone 014. The debris in each settling zone 014 is discharged through the discharge port 1103, realizing the centralized discharge of debris in multiple settling zones 014, which facilitates the discharge of debris in each settling zone 014; it also reduces the number of openings at the bottom of the shell 11 and improves the structural integrity of the shell 11.

[0166] The above describes the specific structure of the duct dust removal component 1. The following describes the electrical equipment 100 in conjunction with the structure of the duct dust removal component 1.

[0167] like Figure 1 As shown, in the electrical equipment 100, the air outlet 012 of the dust removal component 1 is connected to the heat dissipation inlet 341 of the housing 3. The air outlet 012 and the heat dissipation inlet 341 can be directly connected or indirectly connected.

[0168] The housing 11 of the duct dust removal assembly 1 can be part of the enclosure 3; in this case, the air outlet 012 and the heat dissipation inlet 341 are the same ventilation opening. Or, as Figure 13 and Figure 14 As shown, the housing 11 and the box 3 of the duct dust removal component 1 are independent parts. In this case, the duct dust removal component 1 is installed in the box 3, that is, the housing 11 and the box 3 are connected. To facilitate the use of the duct dust removal component 1, the housing 11 and the box 3 are independent parts, and the duct dust removal component 1 is installed in the box 3. In this way, the duct dust removal component 1 itself can form a module, which can be directly installed in the box 3 without changing the structure of the box 3 itself, thus facilitating the installation and use of the duct dust removal component 1.

[0169] In an embodiment where the dust removal component 1 is installed in the housing 3, such as Figure 13 As shown, the dust removal component 1 in the air duct is one unit; or, as shown... Figure 14 As shown, there are two dust removal components 1 in the air duct; or, there are at least three dust removal components 1 in the air duct.

[0170] In embodiments where there are at least two dust removal components 1 in the duct, such as Figure 14 As shown, at least two duct dust removal components 1 can be distributed along the height direction of the housing 3; or, at least two duct dust removal components 1 can be distributed along a second direction. The height direction of the housing 3 is the same as the height direction of the shell 11.

[0171] In embodiments where there are at least two dust removal components 1 in the duct, the at least two dust removal components 1 in the duct can be located on the same side or different sides of the housing 3, depending on the actual situation. This disclosure does not limit this.

[0172] like Figure 1As shown, in some embodiments, the dust removal assembly 1 can be located on the first side of the housing 3 along the first direction. In this way, the dust removal duct 01 and the heat dissipation duct 34 of the dust removal assembly 1 are distributed along the first direction, which can simplify the duct structure.

[0173] In the above embodiment, the enclosure 3 includes a top plate 31 and a bottom plate 32, which are distributed along the height of the enclosure 3. The fan 2 can be installed on the bottom plate 32 of the enclosure 3. In this case, the heat dissipation outlet 342 is installed on the bottom plate 32, and the fan 2 can be located at the heat dissipation outlet 342.

[0174] The fan 2 can also be installed in other locations within the housing 3. For example... Figure 15a and Figure 15b As shown, the fan 2 can be installed on the top plate 31 of the housing 3. In this case, the heat dissipation outlet 342 is installed on the top plate 31 of the housing, and the fan 2 can be located at the heat dissipation outlet 342; or, as shown... Figure 16a and Figure 16b As shown, the enclosure 3 includes an enclosure side panel 33, which is located on the second side of the enclosure 3 along the first direction. The fan 2 can be installed on the enclosure side panel 33. In this case, the heat dissipation outlet 342 is installed on the enclosure side panel 33, and the fan 2 can be located at the heat dissipation outlet 342.

[0175] In this embodiment, the position of the fan 2 can be flexibly adjusted, improving the design flexibility of the electrical equipment 100.

[0176] In this embodiment, the electrical equipment 100 can be a power conversion device, an energy storage device, or other equipment requiring air cooling. The power conversion device can be a photovoltaic inverter, an energy storage converter, or a solid-state transformer, etc.

[0177] In this embodiment of the application, since the electrical equipment 100 includes the duct dust removal component 1, and the duct dust removal component 1 has the above-mentioned technical effects, the electrical equipment 100 also has the corresponding technical effects, which will not be elaborated here.

[0178] The above description is merely a preferred embodiment of this disclosure and an explanation of the technical principles used, and is not intended to limit this disclosure. The described embodiments are only a part of the embodiments of this disclosure, and not all of them. Various modifications and variations can be made to this disclosure by those skilled in the art. The scope of protection in this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalent features without departing from the above-described concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions provided in this disclosure.
