[0003] The main purpose of this application is to propose a dehumidifier and a dehumidification system, aiming to at least improve the technical problem of low efficiency of dehumidifiers in battery production workshops.

[0004] To achieve the above-mentioned objectives, according to some embodiments of the present application, the present application provides a dehumidifier, including a fresh air duct, a return air duct and a rotary dehumidification assembly, the rotary dehumidification assembly including a first dehumidification wheel, a first enhanced fan and a second dehumidification wheel; the first dehumidification wheel, the first enhanced fan and the second dehumidification wheel are sequentially arranged on the air duct path of the fresh air duct, the air inlet of the fresh air duct is connected with the outside world, and the air outlet of the fresh air duct is used to connect with the clean workshop; a filtering device is provided on the return air duct, the outlet end of the return air duct is connected with the fresh air duct and the connection point is located between the first dehumidification wheel and the first enhanced fan, and the inlet end of the return air duct is used to connect with the clean workshop.

[0005] By installing a filter in the dehumidifier's return air duct to filter dust entering the fresh air duct from the cleanroom through the return air duct, the dust content in the return air entering the fresh air duct can be effectively reduced. This also reduces the dust that will be adsorbed on the dehumidifier wheel and refrigeration coil, which helps improve the dehumidification efficiency of the dehumidifier. In addition, by installing a small filter in the return air duct, compared to adding an additional filter device in the cleanroom, it can reduce production costs and save space in the cleanroom.

[0006] In some embodiments, the filter device includes a mounting member and a filter member, the mounting member is mounted on the return air duct, and the filter member is detachably mounted on the mounting member.

[0007] By detachably mounting the filter element on the mounting element, which is mounted on the return air duct, the filter element can be quickly mounted and dismounted, making it convenient to replace the filter element.

[0008] In some embodiments, the mounting member includes two guide bars arranged opposite to each other, and the two guide bars are respectively installed on opposite sides of the outlet end of the return air duct, each guide bar is provided with a mounting groove, and the notches of the two mounting grooves are arranged opposite to each other, and the filter element is a plate-shaped filter element, and the two sides of the plate-shaped filter element are respectively slidably installed on the two mounting grooves.

[0009] By arranging the mounting member as two oppositely arranged guide bars and arranging mounting grooves on the guide bars, the plate-shaped filter element can be installed or removed in a sliding manner, thereby facilitating the installation and removal of the filter element.

[0010] In some embodiments, the mounting groove is provided with a sliding inlet and a sliding outlet along its own extension direction, and a first limiting device is provided at the sliding outlet, and the first limiting device can abut against the filter element.

[0017] By designing the second limiting device to include a rotating shaft that can rotate along its own central axis and a blocking rod connected to the rotating shaft, the blocking rod is rotated by rotating the rotating shaft to open or close the sliding entrance, which is simple to manufacture and very convenient to operate.

[0018] In some embodiments, the filter device further includes a first pressure sensor and a second pressure sensor, wherein the first pressure sensor and the second pressure sensor are respectively disposed on both sides of the filter element along the return air duct.

[0019] By arranging a first pressure sensor and a second pressure sensor on both sides of the filter element along the return air duct, the difference in the amount of dust before and after passing through the filter element is determined based on the pressure difference measured by the first sensor and the second sensor, the dust removal effect of the filter element is judged, and the degree of dirtiness of the filter element is judged accordingly. When the pressure difference reaches the pressure difference threshold, an alarm is issued to prompt the operator to replace the filter element, thereby achieving an early warning effect.

The air taken away is the air that passes through the first refrigeration coil and the first dehumidification wheel, and the humidity of the air is greatly reduced, which can reduce the energy consumed by the first regeneration heater for heating.

Obviously, the described embodiments are only part of the embodiments of this application, not all of them. 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.

[0052] It should be noted that all directional indications in this embodiment (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0053] In addition, the terms "first," "second," and so on, used in this application are for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0054] In this application, unless otherwise specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, "fixed" can mean fixed connection, detachable connection, or integration; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediate medium; it can mean internal connection between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] In addition, the technical solutions of the various embodiments of this application may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually inconsistent or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this application. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0056] The descriptions of directions such as "up", "down", "front", "back", "left" and "right" in this application are based on the directions shown in the accompanying drawings and are only used to explain the relative positional relationship between the components in the postures shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0057] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0058] Battery production is typically carried out in cleanrooms, where dehumidifiers are installed to dehumidify and filter incoming air, ensuring that the air reaches the required humidity and cleanliness levels. However, in battery production cleanrooms, the applicant discovered that the dehumidifier's effectiveness decreased significantly with operating time.

[0059] After careful research, the applicant discovered that generally clean workshops do not produce dust, but the production of batteries does produce dust. The dust enters the dehumidifier through the return air duct of the dehumidifier and is adsorbed on the dehumidifier wheel or the freezing disk water pipe, reducing the dehumidification effect of the dehumidifier. Since general clean workshops do not produce dust, there is currently no solution in the relevant technology to treat the return air from the clean workshop to the dehumidifier. It is relatively easy to think of adding a return air filter device in the workshop to filter and remove dust from the air discharged from the clean workshop before it flows into the dehumidifier. However, the current return air filter device has a complex structure and takes up a large space. Not only is the production cost high, but it is also inconvenient to install and maintain.

[0060] To this end, the present application provides a dehumidifier, including a fresh air duct, a return air duct and a rotary dehumidification assembly, wherein the rotary dehumidification assembly includes a first dehumidification wheel, a first enhanced fan and a second dehumidification wheel; the first dehumidification wheel, the first enhanced fan and the second dehumidification wheel are sequentially arranged on the air duct path of the fresh air duct, the air inlet of the fresh air duct is connected to the outside, and the air outlet of the fresh air duct is used to connect with the clean room; a filtering device is provided on the return air duct, the outlet end of the return air duct is connected to the fresh air duct and the connection point is located between the first dehumidification wheel and the first enhanced fan, and the inlet end of the return air duct is used to connect with the clean room. By providing a filtering device on the return air duct, the air entering the dehumidifier is filtered and dust-removed, which can reduce the risk of dust in the clean room entering the dehumidifier and improve the dehumidification efficiency of the dehumidifier. Moreover, it is only necessary to provide a filtering device (such as a filter) in the return air duct of the dehumidifier, which has low production cost and does not require additional space in the clean room.

[0061] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The electrical device may be the vehicle 1000, and the vehicle 1000 may be a fuel vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 may be provided at the bottom, head, or tail of the vehicle 1000. The battery 100 may be used to power the vehicle 1000, for example, the battery 100 may serve as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating, and operating power requirements of the vehicle 1000 during driving.

[0062] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0063] Please refer to Figure 2 , Figure 2This is a schematic diagram of the exploded structure of a battery 100 provided in some embodiments of the present application. The battery 100 includes a housing 10 and battery cells 20, with the battery cells 20 housed within the housing 10. The housing 10 provides storage space for the battery cells 20 and can have various structures. In some embodiments, the housing 10 can include a first portion 11 and a second portion 12, which overlap each other and together define a storage space for the battery cells 20. The second portion 12 can be a hollow structure with one end open. The first portion 11 can be a plate-like structure, with the first portion 11 overlapping the open side of the second portion 12, so that the first portion 11 and the second portion 12 together define a storage space. Alternatively, the first portion 11 and the second portion 12 can each be a hollow structure with one end open, with the open side of the first portion 11 overlapping the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder or a rectangular parallelepiped.

[0064] In the battery 100, there may be multiple cells 20, and the multiple cells 20 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections among the multiple cells 20. The multiple cells 20 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery 20 may be housed within the housing 10. Alternatively, the battery 100 may be constructed by first connecting multiple cells 20 in series, in parallel, or in a hybrid connection to form a battery module, which is then connected in series, in parallel, or in a hybrid connection to form a single unit housed within the housing 10. The battery 100 may also include other structures, such as a busbar assembly to achieve electrical connectivity between the multiple cells 20.

[0065] Each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 can be cylindrical, flat, rectangular, or in other shapes.

[0066] The present application provides a dehumidifier.

[0067] Reference Figure 3 and Figure 4According to some embodiments of the present application, the dehumidifier 2100 includes a fresh air duct 1, a return air duct 3 and a rotary dehumidification assembly, and the rotary dehumidification assembly includes a first dehumidification wheel 41, a first enhanced fan 47 and a second dehumidification wheel 43; the first dehumidification wheel 41, the first enhanced fan 47 and the second dehumidification wheel 43 are arranged in sequence on the air duct path of the fresh air duct 1, the air inlet of the fresh air duct 1 is connected to the outside world, and the air outlet of the fresh air duct 1 is used to connect with the clean workshop 203; a filtering device 5 is provided on the return air duct 3, and the outlet end of the return air duct 3 is connected with the fresh air duct 1 and the connection point is located between the first dehumidification wheel 41 and the first enhanced fan 47, and the inlet end of the return air duct 3 is used to connect with the clean workshop 203.

[0068] The clean room 203 is a workshop for manufacturing batteries 100. The clean room 203 is generally dust-free, but dust is generated during the production process of the batteries 100 in the clean room 203. The fresh air duct 1 is the air duct that draws air from the outside, processes it through the various components set on the path of the fresh air duct 1, and finally flows into the clean room 203. The return air duct 3 is the air duct that flows out of the clean room 203 and back into the dehumidifier 2100. The specific air flow direction is as follows: Figure 4 As shown by the arrow in the middle. Specifically, the outlet end of the return air duct 3 is connected to the fresh air duct 1, and the connection point is located between the first dehumidification wheel 41 and the first enhanced fan 47. The wind entering the fresh air duct 1 from the return air duct 3 will flow through the first enhanced fan 47 and the second dehumidification wheel 43 in sequence. The filter device 5 is installed in the return air duct 3, and can filter the air flowing from the return air duct 3 into the fresh air duct 1. The filtration here is mainly to filter the dust, so as to at least reduce the dust content in the air flowing from the return air duct 3 into the fresh air duct 1, thereby reducing the possibility of dust in the return air being adsorbed on the dehumidification wheel or the refrigeration coil, and thus reducing the risk of the dehumidification efficiency of the dehumidifier 2100 being reduced due to dust in the return air entering the interior of the dehumidifier 2100.

[0069] By providing a filter device 5 within the return air duct 3 of the dehumidifier 2100 to filter dust entering the fresh air duct 1 from the cleanroom 203 through the return air duct 3, the dust content in the return air entering the fresh air duct 1 from the return air duct 3 can be effectively reduced, thereby reducing the dust that would be adsorbed on the dehumidifier wheel and the refrigeration coil, which is beneficial for improving the dehumidification efficiency of the dehumidifier 2100. Furthermore, by providing a small filter device 5 within the return air duct 3, the filter device is installed inside the dehumidifier. Compared with adding an additional filter device in the cleanroom 203, this can reduce manufacturing costs and save space in the cleanroom 203.

[0070] Reference Figure 5In some embodiments, the filter device 5 includes a mounting member 51 and a filter member 52 . The mounting member 51 is mounted on the return air duct 3 , and the filter member 52 is detachably mounted on the mounting member 51 .

[0071] Mounting member 51 is a component mounted on return air duct 3. Specifically, it can be mounted on the inner wall of return air duct 3 or on the edge of the opening at the outlet of return air duct 3. Mounting member 51 provides support for filter element 52. Filter element 52 is used to filter the return air from return air duct 3 to fresh air duct 1 to reduce the dust content in the return air. Filter element 52 is air-permeable and therefore does not affect the flow of air from return air duct 3 into fresh air duct 1. For example, filter element 52 may include a filter screen with fine mesh that allows air to pass but blocks dust. Because filter element 52 accumulates dust after use, reducing its filtering effectiveness or affecting the flow of return air, it needs to be replaced periodically. Therefore, filter element 52 is designed to be removably mounted on mounting member 51 to facilitate replacement. Of course, in other embodiments, mounting member 51 can also be designed to be removably connected to return air duct 3, allowing the entire filter device 5 to be replaced.

[0072] By detachably mounting the filter element 52 on the mounting element 51 , and the mounting element 51 being mounted on the return air duct 3 , the filter element 52 can be quickly mounted and dismounted, making it convenient to replace the filter element 52 .

[0073] Reference Figure 6 In some embodiments, the mounting member 51 includes two guide bars 511 arranged opposite to each other. The two guide bars 511 are respectively installed on opposite sides of the outlet end of the return air duct 3. Each guide bar 511 is provided with a mounting groove 5111. The notches of the two mounting grooves 5111 are arranged opposite to each other. Figure 8 The filter element 52 is a plate-shaped filter element 52 , and both sides of the plate-shaped filter element 52 are slidably mounted on the two mounting grooves 5111 .

[0074] The guide bar 511 is long and narrow, and the mounting groove 5111 extends along the length of the guide bar 511. Specifically, the two guide bars 511 are arranged opposite each other and mounted on either side of the return air duct 3. Alternatively, the two ends of the guide bar 511 may be connected to the return air duct 3, and the two mounting grooves 5111 of the two guide bars 511 are arranged opposite each other. The filter element 52 may be a plate-shaped filter element 52, and the two opposing sides of the plate-shaped filter element 52 are slidably mounted in the two mounting grooves 5111, so that the filter element 52 can be installed or removed by sliding. Specifically, the plate-shaped filter element 52 may be a plate-type air filter. Plate-type air filters are widely used in industries such as steel, electronics, chemicals, automobiles, environmental protection, and electricity. They are widely used in centrifugal compressor filter rooms and for dust removal, oil removal, and coarse filtration in various air conditioning systems. Plate-type air filters are made of synthetic glass fiber. They have a large dust holding capacity and a long service life, and are often used for air filtration.

[0075] By configuring the mounting member 51 as two oppositely disposed guide bars 511 and providing mounting grooves 5111 on the guide bars 511 , the plate-shaped filter element 52 can be installed or removed by sliding, thereby facilitating installation and removal of the filter element 52 .

[0076] Reference Figure 6 In some embodiments, the mounting groove 5111 is provided with a sliding inlet 5112 and a sliding outlet 5113 along its extension direction, and a first limiting device 53 is provided at the sliding outlet 5113 , and the first limiting device 53 can abut against the filter element 52 .

[0077] The extension direction of the installation groove 5111 is actually the length direction of the guide bar 511, or in other words, the extension direction of the guide bar 511. The two guide bars 511 are spaced relative to each other and have two openings along the length direction of the guide bar 511. The opening through which the filter element 52 enters is defined as the sliding entrance 5112, and the opening on the side away from the sliding entrance 5112 is defined as the sliding exit 5113. During the installation of the filter element 52, if the installation force is too great or the distance the filter element 52 is pushed exceeds a certain stroke, the filter element 52 may slide out of the sliding exit 5113. Therefore, a first stopper 53 can be provided at the sliding exit 5113. The first stopper 53 can take various forms, such as a stopper plate, a stopper rod, or a stopper protrusion provided on the sliding exit 5113. The specific structure of the first stopper 53 is not specifically limited in this application. The first stopper 53 is used to abut against the filter element 52 to reduce the risk of the filter element 52 sliding out of the sliding exit 5113.

[0078] By arranging the first limiting device 53 at the sliding outlet 5113 , the first limiting device 53 can limit the filter element 52 , thereby preventing the filter element 52 from moving beyond the line and sliding off the sliding outlet 5113 .

[0079] Reference Figure 6 In some embodiments, the first limiting device 53 includes a limiting rod, which is fixedly installed on the sliding outlet 5113.

[0080] The limiting rod is a rod-shaped structure. One end of the limiting rod can be mounted on one of the guide bars 511, and the other end can extend toward the other guide bar 511. Alternatively, the two ends of the limiting rod can be connected to two guide bars 511 respectively. The number of limiting rods can be one or more, and the installation direction can be inclined or vertical. This application does not specifically limit the number and installation direction of the limiting rods. Of course, the limiting rod can also be installed on the return air duct 3 and extend toward the sliding outlet 5113.

[0081] By designing the first limiting device 53 as a limiting rod and fixing the limiting rod at the sliding outlet 5113, the risk of the filter element 52 sliding off the sliding outlet 5113 can be effectively reduced, and the manufacturing and installation are convenient.

[0082] Reference Figure 6 and Figure 7 In some embodiments, the sliding entrance 5112 is provided with a second limiting device 54 , and the second limiting device 54 can be rotated to open or close the sliding entrance 5112 .

[0083] As mentioned above, the sliding entrance 5112 is the entrance for the filter element 52 to enter. It needs to be opened when installing the filter element 52. However, after the filter element 52 is installed, there is a risk that the filter element 52 will slip out of the sliding entrance 5112. Therefore, a second limiting device 54 can be provided at the sliding entrance 5112. The second limiting device 54 is installed on the guide bar 511 or the return air duct 3 and is hinged to the return air duct 3 or the guide bar 511 so as to be able to rotate. For example, when the filter element 52 needs to be installed, it is rotated to the first position, at which point the sliding entrance 5112 is open. After the filter element 52 is installed, it is rotated to the second position, specifically moving to the opening of the sliding entrance 5112, blocking and closing the sliding entrance 5112. This can reduce the risk of the filter element 52 slipping out of the sliding entrance 5112.

[0084] By setting a second limiting device 54 at the sliding entrance 5112, and the second limiting device 54 is hinged to the mounting member 51 or the return air duct 3, the second limiting device 54 can be rotated to open or close the sliding entrance 5112. When the filter element 52 needs to be installed, the second limiting device 54 will be rotated to open the sliding entrance 5112 to facilitate the installation of the filter element 52. After the installation is completed, the second limiting device 54 will be rotated to close the sliding entrance 5112 to reduce the risk of the filter element 52 slipping from the sliding entrance 5112.

[0085] Reference Figure 7In some embodiments, the second limiting device 54 includes a rotating shaft 541 and a blocking rod 542 connected to the rotating shaft 541 , and the blocking rod 542 is driven to rotate by driving the rotating shaft 541 to open or close the sliding entrance 5112 .

[0086] The rotating shaft 541 can be rotatably mounted on the mounting member 51 or the return air duct 3, that is, the rotating shaft 541 can rotate around its own central axis, and one end of the blocking rod 542 is mounted on the rotating shaft 541. In a specific embodiment, the rotating shaft 541 and the blocking rod 542 can be connected vertically, that is, in an L-shape. For example, when the filter element 52 needs to be installed, the blocking rod 542 can be rotated to the first position by rotating the rotating shaft 541, at which time the sliding entrance 5112 is opened; after the filter element 52 is installed, the blocking rod 542 can be rotated to the second position by rotating the rotating shaft 541, specifically moving to the opening of the sliding entrance 5112, blocking and closing the sliding entrance 5112, thereby reducing the risk of the filter element 52 slipping from the sliding entrance 5112.

[0087] By designing the second limiting device 54 to include a rotating shaft 541 that can rotate along its own central axis, and a blocking rod 542 connected to the rotating shaft 541, the blocking rod 542 is rotated by rotating the rotating shaft 541 to open or close the sliding entrance 5112, which is simple to manufacture and very convenient to operate.

[0088] Reference Figure 5 In some embodiments, the filter device 5 further includes a first pressure sensor 6 and a second pressure sensor 7 , which are respectively arranged on both sides of the filter element 52 along the return air direction of the return air duct 3 .

[0089] Return air direction Figure 5 The direction of the arrow in the middle is shown. Both sides of the filter element 52 can be the return air duct 3, that is, the filter element 52 is installed in the return air duct 3 and is a distance away from the outlet end of the return air duct 3. It is also possible that one side of the filter element 52 is the return air duct 3 and the other side is the fresh air duct 1, that is, Figure 5The upper side of the diagram is the return air duct 3, and the lower side is the fresh air duct 1. That is, the filter element 52 is installed at the opening at the outlet of the return air duct 3. A pressure sensor senses pressure signals and converts them into outputtable electrical signals according to a specific rule. It typically consists of a pressure sensitive element and a signal processing unit. The first pressure sensor 6 and the second pressure sensor 7 here differ only in their installation locations and are distinguished by different names; their structures and functions may be identical. Specifically, the first pressure sensor 6 and the second pressure sensor 7 are respectively installed on either side of the filter element 52 along the return air duct 3. "On either side along the return air direction of the return air duct 3" refers to the first pressure sensor 6 being installed before the filter element 52 to measure the pressure of the unfiltered return air, and the second pressure sensor 7 being installed after the filter element 52 to measure the pressure of the filtered return air. Alternatively, the first pressure sensor 6 may be installed after the filter element 52 to measure the pressure of the filtered return air, and the second pressure sensor 7 may be installed before the filter element 52 to measure the pressure of the unfiltered return air. By separately measuring the return air pressure before and after the filter element 52, the pressure differential of the return air passing through the filter element 52 can be determined. The pressure differential increases as the amount of dust filtered by the filter element 52 increases. In other words, a larger calculated pressure differential indicates more dust is filtered out. To enable automatic alarms, a pressure differential threshold can be set. If the pressure differential reaches the threshold, indicating a significant decrease in the filtering effect of the filter element 52, an alarm can be sounded, prompting the operator to replace the filter element 52.

[0090] By arranging a first pressure sensor 6 and a second pressure sensor 7 on both sides of the filter element 52 along the return air duct 3, the difference in the amount of dust before and after passing through the filter element 52 is determined based on the pressure difference measured by the first sensor and the second sensor, the dust removal effect of the filter element 52 is determined, and the degree of dirtiness of the filter element 52 is determined accordingly. When the pressure difference reaches the pressure difference threshold, an alarm is issued to prompt the operator to replace the filter element 52, thereby achieving an early warning effect.

[0091] Reference Figure 4 In some embodiments, the dehumidifier 2100 further includes a regeneration air duct 2, and the rotary dehumidification assembly further includes a first regeneration heater 45, a second regeneration heater 46 and a regeneration wind wheel 401; the first regeneration heater 45, the second dehumidification wheel 43, the second regeneration heater 46, the first dehumidification wheel 41 and the regeneration wind wheel 401 are sequentially arranged on the regeneration air duct 2, one end of the regeneration air duct 2 is connected to the fresh air duct 1, and the other end of the regeneration air duct 2 is connected to the outside world.

[0092] The regeneration duct 2 is used to draw air from the fresh air duct 1. Specifically, it may remove a portion of the fresh air from the location after passing through the first dehumidification wheel 41 and the first booster fan 47. The air in the regeneration duct 2 is first heated by the first regeneration heater 45 to increase its temperature. The high-temperature air passes through the second dehumidification wheel 43, where it evaporates moisture from the second dehumidification wheel 43, regenerating the second dehumidification wheel 43. The air in the regeneration duct 2 is then heated by the second regeneration heater 46 to increase its temperature. The high-temperature air passes through the first dehumidification wheel 41, where it evaporates moisture from the first dehumidification wheel 41, regenerating the first dehumidification wheel 41. The regeneration fan 401 is used to provide power for the air flow in the regeneration duct 2, accelerating the air flow and improving the operating efficiency of the dehumidifier 2100.

[0093] By providing the regeneration air duct 2 , part of the air can be taken away from the fresh air duct 1 for regeneration of the first dehumidification wheel 41 and the second dehumidification wheel 43 , thereby enabling the first dehumidification wheel 41 and the second dehumidification wheel 43 to work in a cycle.

[0094] Reference Figure 4 In some embodiments, the dehumidifier 2100 also includes a first refrigeration coil 42, a second refrigeration coil 44, a third refrigeration coil 49, a first filter 402, a second filter 403 and a second enhanced fan 48; the first filter 402, the first refrigeration coil 42, the first dehumidifier 2100, the first enhanced fan 47, the second filter 403, the second refrigeration coil 44, the second dehumidifier 2100, the third refrigeration coil 49 and the second enhanced fan 48 are arranged in sequence on the air duct path of the fresh air duct 1, and the connection point between the regeneration air duct 2 and the fresh air duct 1 is located between the first enhanced fan 47 and the second filter 403.

[0095] The first refrigeration coil 42, the second refrigeration coil 44 and the third refrigeration coil 49 all play a role in cooling the air, so that part of the water vapor in the air is liquefied, which plays a role in preliminary dehumidification. The first booster fan 47 and the second booster fan 48 are both used to increase the power of the air flow, accelerate the flow of the air, and improve the working efficiency of the dehumidifier 2100. The first filter 402 and the second filter 403 both play a filtering role, which can purify and remove dust from the air. The connection point between one end of the regeneration air duct 2 and the fresh air duct 1 is located between the first booster fan 47 and the second filter 403, which takes away the air that has passed through the first refrigeration coil 42 and the first dehumidification wheel 41, and the humidity of the air is greatly reduced.

[0096] By setting up a refrigeration coil (including a first refrigeration coil 42, a second refrigeration coil 44 and a third refrigeration coil 49), the function of preliminary cooling and dehumidification is achieved, and filters (including a first filter 402 and a second filter 403) are set up to purify the air. A first booster fan 47 and a second booster fan 48 are set up to provide power for the flow of air, and the connection between one end of the regeneration air duct 2 and the fresh air duct 1 is located between the first booster fan 47 and the second filter 403. The air taken away is the air that passes through the first refrigeration coil 42 and the first dehumidification wheel 41, and the humidity of the air is greatly reduced, which can reduce the energy consumed by the first regeneration heater 45 for heating.

[0097] According to some embodiments of the present application, the present application provides a dehumidifier 2100, including a fresh air duct 1, a return air duct 3, a regeneration duct 2 and a rotary dehumidification component, the rotary dehumidification component including a first dehumidification wheel 41, a first enhanced fan 47, a second dehumidification wheel 43, a first regeneration heater 45, a second regeneration heater 46, a regeneration wind wheel 401, a first refrigeration coil 42, a second refrigeration coil 44, a third refrigeration coil 49, a first filter 402, a second filter 403 and a second enhanced fan 48; the first filter 402, the first refrigeration coil 42, the first dehumidifier 2100, the first dehumidifier 2100, the first dehumidification wheel 41, the first enhanced fan 47, the second dehumidification wheel 43, the first regeneration heater 45, the second regeneration heater 46, the regeneration wind wheel 401, the first refrigeration coil 42, the second refrigeration coil 44, the third refrigeration coil 49, the first filter 402, the second filter 403 and the ... 2100, the first enhanced fan 47, the second filter 403, the second refrigeration coil 44, the second dehumidifier 2100, the third refrigeration coil 49 and the second enhanced fan 48 are arranged in sequence on the air duct path of the fresh air duct 1, the air inlet of the fresh air duct 1 is connected with the outside world, and the air outlet of the fresh air duct 1 is used to connect with the clean workshop 203; a filtering device 5 is provided on the return air duct 3, and the outlet end of the return air duct 3 is connected with the fresh air duct 1 and the connection point is located between the first dehumidification wheel 41 and the first enhanced fan 47, and the inlet end of the return air duct 3 is used to connect with the clean workshop 203. The filter device 5 includes a mounting member 51 and a filter member 52. The mounting member 51 is mounted on the return air duct 3. The filter member 52 is detachably mounted on the mounting member 51. The mounting member 51 includes two guide bars 511 arranged opposite to each other. The two guide bars 511 are respectively mounted on opposite sides of the outlet end of the return air duct 3. Each guide bar 511 is provided with a mounting slot 5111. The notches of the two mounting slots 5111 are arranged opposite to each other. The filter member 52 is a plate-shaped filter member 52. The two sides of the plate-shaped filter member 52 are respectively slidably mounted on the two mounting slots 5111. The mounting slot 5111 is provided with a sliding inlet 5112 and a sliding outlet 5113 along its extension direction. A limiting rod is provided at the sliding outlet 5113. The limiting rod is fixedly mounted on the sliding outlet 5113. The limiting rod can abut against the filter member 52 to reduce the risk of the filter member 52 slipping out of the sliding outlet 5113. The sliding inlet 5112 is provided with a rotating shaft 541 and a blocking rod 542 connected to the rotating shaft 541. By driving the rotating shaft 541 to rotate, the blocking rod 542 is driven to rotate to open or close the sliding inlet 5112. The filter device 5 also includes a first pressure sensor 6 and a second pressure sensor 7, which are respectively arranged on both sides of the filter element 52 along the return air direction of the return air duct 3. The first regeneration heater 45, the second dehumidification wheel 43, the second regeneration heater 46, the first dehumidification wheel 41 and the regeneration wind wheel 401 are arranged in sequence on the regeneration air duct 2, one end of the regeneration air duct 2 is connected to the fresh air duct 1, and the other end of the regeneration air duct 2 is connected to the outside world. The embodiment of the present application can reduce the dust in the clean room 203 from flowing into the dehumidifier 2100 from the return air duct 3, which is conducive to improving the dehumidification efficiency of the dehumidifier 2100. In addition, the filter device 5 has a low production cost, is easy to install and replace, and does not take up additional space in the clean room 203.

[0098] Reference Figure 3 According to some embodiments of the present application, the present application provides a dehumidification system 2000, including a clean workshop 203 and an air supply duct 201 and a return air duct 202 respectively connected to the clean workshop 203, and the above-mentioned dehumidifier 2100, the air outlet of the fresh air duct 1 is connected to the clean workshop 203 through the air supply duct 201, and the return air duct 3 is connected to the clean workshop 203 through the return air duct 202.

[0099] Cleanroom 203 is the workshop where batteries 100 are manufactured. The manufacturing process of batteries 100 generates dust, which flows through return air duct 202 into return air duct 3. Then, through return air duct 3, it enters dehumidifier 2100, where it may be adsorbed on the dehumidifier wheel or refrigeration coil of dehumidifier 2100. The air outlet of fresh air duct 1 is connected to cleanroom 203 via air supply duct 201. In other words, air from the outside flows through fresh air duct 1, is processed by various components in fresh air duct 1, and then outputs clean, dry air to cleanroom 203. The return air duct 3 is connected to the clean workshop 203 through the return air pipe 202. The dusty air in the clean workshop 203 will flow into the return air duct 3 through the return air duct 202. Since the return air duct 3 is provided with a filter device 5, the filter device 5 will filter the return air in the return air duct 3 before entering the fresh air duct 1, reducing the dust in the return air before entering the fresh air duct 1, which can reduce the adverse effects of dust adsorption inside the dehumidifier 2100 on the efficiency of the dehumidifier 2100.

[0100] The air outlet of the fresh air duct 1 is connected to the clean workshop 203 through the air supply duct 201, and the return air duct 3 is connected to the clean workshop 203 through the return air duct 202, and a filter device 5 is provided in the return air duct 3. The dehumidification system 2000 thus formed includes any technical solution of all embodiments of the above-mentioned dehumidifier 2100, and therefore has at least all the beneficial effects brought by any of the above-mentioned technical solutions, which will not be repeated here.

[0101] Reference Figure 3 In some embodiments, the clean room 203 includes an air inlet space 2032 and a return air space 2031. The air inlet space 2032 is connected to the air supply duct 201, and the return air space 2031 is connected to the return air duct 202. A return air louver 204 is provided between the air inlet space 2032 and the return air space 2031, which opens toward the return air space 2031.

[0102] The cleanroom 203 is divided into two areas by the return air space 2031 and the inlet air space 2032. The inlet air space 2032 houses equipment for manufacturing the battery 100, and the battery 100 is manufactured there. Clean air is input from the fresh air duct 1 through the air supply duct 201 and enters the inlet air space 2032 of the cleanroom 203. Return air louvers 204 are provided between the inlet air space 2032 and the return air space 2031, opening toward the return air space 2031. This means that the air generally flows from the inlet air space 2032 to the return air space 2031. In other words, dust-laden air flows from the inlet air space 2032 to the return air space 2031, then passes through the return air duct 202 connected to the return air space 2031, is filtered through the return air duct 3, and flows into the dehumidifier 2100, achieving air recycling. Specifically, the return air space 2031 can be located outside the air inlet space 2032, so that the battery production equipment can be concentrated in the middle of the clean workshop 203, which is convenient for the arrangement of the equipment.

[0103] By designing the clean workshop 203 to include an air inlet space 2032 and a return air space 2031, and designing return air louvers 204 that open toward the return air space 2031 in the air inlet space 2032 and the return air space 2031, the main flow direction of the air is controlled to be from the air inlet space 2032 to the return air space 2031, so that the air flowing in from the fresh air duct 1 will enter the air inlet space 2032 through the air supply duct 201, and flow into the return air duct 3 through the return air space 2031 and the return air duct 202, thereby realizing the flow and circulation of air in the clean workshop 203.

[0104] Reference Figure 3 In some embodiments, the air supply duct 201 is further provided with a flow regulating valve 2011 and a third filter 2012 .

[0105] Flow control valve 2011 is used to adjust the air volume within air supply duct 201, specifically the amount of air flowing from fresh air duct 1 through air supply duct 201 into clean room 203. Flow control valve 2011 can be controlled based on the dust content in clean room 203 to adjust the air volume. Third filter 2012, a high-efficiency filter, is used to further remove dust from the air entering the clean room.

[0106] By providing a flow control valve 2011 on the air supply duct 201 , the air supply volume can be adjusted according to the dust content in the clean room 203 , and by providing a third filter 2012 , the cleanliness of the air entering the clean room 203 can be further improved.

[0107] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings under the application concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
