Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a heating device and its control method. Background Technology

[0002] With the rapid development of data centers and industrial manufacturing, many application scenarios require high-precision control of parameters such as ambient temperature, humidity, cleanliness, and airflow distribution. Air conditioning can precisely regulate environmental parameters to ensure the stable operation of high-value equipment or processes. Its application scenarios cover multiple strategic industries such as information technology, healthcare, and advanced manufacturing, and it is an important infrastructure for modern industrial and scientific research systems.

[0003] Currently, the heating device of an air conditioner is one of the core components for achieving constant temperature control. In the production process, the heating device of the air conditioner usually needs to heat at least part of the incoming gas with special heating power so that the temperature of that part of the incoming gas can be within a preset range for processing special parts or maintaining special equipment.

[0004] However, existing air conditioner heating devices do not have the function of localized directional adjustment, thus failing to achieve the effect of localized heating. Summary of the Invention

[0005] In view of this, this application provides a heating device and its control method to solve the technical problem that the heating device of the prior art air conditioner does not have the function of local directional adjustment, thus making it impossible to achieve local heating.

[0006] This application provides a heating device, which includes a housing, a flow guiding assembly, a driving assembly, and a detection device. The flow guiding assembly, the driving assembly, and the detection device are all installed inside the housing. The flow guiding assembly includes multiple flow guiding blades that are spaced apart and form an air supply channel between adjacent flow guiding blades. Each flow guiding blade is provided with a heating film for heating the gas in the air supply channel. The driving assembly is directly or indirectly connected to each flow guiding blade and is used to drive at least one flow guiding blade to rotate relative to the housing. The detection device is located on the air inlet side or air outlet side of the flow guiding assembly and is used to detect the gas temperature on the air inlet side or air outlet side of the flow guiding assembly.

[0007] The detection device, drive assembly, and heating film are electrically or signal-connected to the control system. The control system can control the drive assembly to start or stop, and / or control the heating film to open or close, based on the detection results of the detection device.

[0008] In this embodiment, the heating device can achieve individual adjustment of its local structure and individual heating of its local temperature, thereby enabling directional flow of gas and local heating for processing of special components or maintenance of special instruments within the target area.

[0009] Among them, the detection device and control system can realize the closed-loop control of gas temperature detection, adjustment and heating of the heating device, thereby shortening the response time, improving work efficiency, and facilitating efficient and accurate real-time dynamic adjustment of gas temperature, thus improving the flexibility of the heating device in the working process.

[0010] Meanwhile, since the multiple guide vanes and heating films are all connected in parallel, the risk of the entire heating device shutting down due to damage to some guide vanes and / or some heating films is avoided. Only the damaged parts need to be replaced individually, which not only helps to reduce maintenance costs and improve maintenance efficiency, but also helps to improve the stability and reliability of the heating device during operation.

[0011] In addition, controlling the heating process of the local heating film can help reduce energy consumption, improve energy utilization, reduce the operating cost of the heating device, and better meet actual usage needs.

[0012] In one possible implementation, the guide vanes extend along a first direction x and are spaced apart along a second direction y. The guide assembly also includes a connecting plate, which is distributed along the first direction x on both sides of the guide vanes to connect at least two adjacent guide vanes to form a guide vane group. The drive assembly is connected to the guide vanes through the connecting plate.

[0013] In one possible implementation, the guide vane includes a first vane and a second vane, which are alternately arranged along a second direction y. The width of the first vane is L1, and the width of the second vane is L2, and L1 and L2 satisfy 0.25≤L1 / L2≤1.

[0014] In one possible implementation, the guide vane or connecting plate is provided with a rotating shaft, and the drive assembly includes a drive motor and a transmission gear set. The drive motor is connected to the rotating shaft through the transmission gear set so that at least one guide vane rotates relative to the housing.

[0015] In one possible implementation, the flow guiding assembly includes a first flow guiding group and a second flow guiding group, which are distributed at intervals along a third direction z. The projection of any flow guiding blade in the first flow guiding group and the projection of any flow guiding blade in the second flow guiding group have a first included angle α, which satisfies 0°<α≤90°.

[0016] In one possible implementation, the area of ​​the guide vane is S1, the area of ​​the heating film is S2, and S1 and S2 satisfy 0.1≤S2 / S1≤1.

[0017] In one possible implementation, the heating film includes an electric heating layer and an insulating layer, with the insulating layer covering both sides of the electric heating layer. The electric heating layer is electrically connected to a heating power source, and the heating power source is electrically connected or signal-connected to a control system. The control system can also control the power of the heating power source to increase or decrease based on the detection results of the detection device.

[0018] In one possible implementation, the heating device further includes a first flow equalization plate, which is installed inside the housing and located on the air inlet side of the flow guiding component. The first flow equalization plate is provided with a plurality of first through holes, which are distributed at intervals along the first direction x and the second direction y, and each first through hole is connected to the inlet end of the air supply channel.

[0019] In one possible implementation, the heating device further includes a second flow equalization plate, which is installed inside the housing and located on the air outlet side of the flow guiding assembly. The second flow equalization plate is provided with a plurality of second through holes, which are distributed at intervals along the first direction x and the second direction y, and each second through hole is connected to the outlet end of the air supply channel.

[0020] In one possible implementation, the detection device includes multiple detection elements.

[0021] When the heating device includes a first flow equalization plate, multiple detectors are distributed at intervals along the first direction x and the second direction y on the first flow equalization plate, and the detectors are arranged adjacent to the first through hole for detecting the gas temperature in the first through hole.

[0022] When the heating device includes only the second flow equalization plate or both the first flow equalization plate and the second flow equalization plate, multiple detection elements are distributed at intervals along the first direction x and the second direction y on the second flow equalization plate, and the detection elements are arranged adjacent to the second through hole to detect the gas temperature in the second through hole.

[0023] This application also provides a control method for a heating device, wherein the heating device is any of the heating devices described above, used to transfer gas to a target area, the preset temperature of the target area being T0, and the control method includes:

[0024] The first gas temperature T1 on the air inlet side of the air guide assembly is detected, or the second gas temperature T2 on the air outlet side of the air guide assembly is detected.

[0025] When T0 and T1 satisfy T0 > T1 or T0 and T2 satisfy T0 > T2, the control drive assembly drives at least one guide vane to rotate so that the air supply channel is aligned with the target area, and controls the heating film to be in the open state to heat the gas in the air supply channel.

[0026] When T0 and T1 satisfy T0≤T1 or T0 and T2 satisfy T0≤T2, the control drive assembly drives at least one guide vane to rotate so that the air supply channel is aligned with the target area and controls the heating film to be in the closed state.

[0027] In this embodiment, when the heating device includes a first flow equalization plate, the first flow equalization plate is provided with a first detection element for detecting the gas temperature in adjacent first through holes, so that the control system can control the drive assembly to drive the partial guide vanes to rotate and / or control the partial heating film to heat according to the detection result of the first detection element. Alternatively, when the heating device includes only a second flow equalization plate or includes both a first flow equalization plate and a second flow equalization plate, the second flow equalization plate is provided with a second detection element for detecting the gas temperature in adjacent second through holes, so that the control system can control the drive assembly to drive the partial guide vanes to rotate and / or control the partial heating film to heat according to the detection result of the second detection element, thereby enabling the heating device to process special components or maintain special instruments in the target area.

[0028] This design allows the control system to promptly adjust the operating status of the guide assembly and / or heating film based on the temperature of the gas flowing into or out of the heating device, thus meeting the needs of processing special components or maintaining special equipment within the target area. The real-time detection of gas temperature by the monitoring device helps shorten response time and improve work efficiency, enabling the control system to efficiently and accurately adjust the gas temperature dynamically in real time, further enhancing the flexibility of the heating device during operation.

[0029] In one possible implementation, the heating device further includes a heating power source electrically connected to the heating film. The initial heating power of the heating power source is P0. During the process of controlling the drive assembly to drive at least one guide vane to rotate, aligning the air delivery channel with the target area, and controlling the heating film to be in an open state to heat the gas within the air delivery channel, the control method further includes:

[0030] The power of the heating power supply is controlled to be at the first heating power P1, and P0 and P1 satisfy P0 < P1.

[0059] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0061] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0062] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0063] Embodiments of this application provide a heating device, such as... Figure 1 , Figure 2 and Figure 6 As shown, the heating device includes a housing 1, a flow guiding component 2, a drive component (not shown in the figure), and a detection device 3. The flow guiding component 2, the drive component, and the detection device 3 are all installed inside the housing 1.

[0064] The flow guiding assembly 2 includes multiple flow guiding blades 211, which are spaced apart and form an air supply channel 212 between adjacent blades. Each flow guiding blade 211 is equipped with a heating film (not shown in the figure) for heating the gas in the air supply channel 212. The drive assembly is directly or indirectly connected to each flow guiding blade 211 and is used to drive at least one flow guiding blade 211 to rotate relative to the housing 1. The detection device 3 is located on the air inlet or air outlet side of the flow guiding assembly 2 and is used to detect the gas temperature on the air inlet or air outlet side of the flow guiding assembly 2.

[0065] Meanwhile, the detection device 3, the drive assembly, and the heating film are electrically or signal connected to the control system (not shown in the figure). The control system can control the drive assembly to start or stop, and / or control the heating film to open or close, based on the detection results of the detection device 3.

[0066] In addition, this heating device can be applied to industrial precision air conditioners, making it suitable for working environments with strict requirements for environmental parameters such as temperature and gas distribution.

[0067] It should be noted that in the embodiments of this application, the first direction x is defined as the length direction of the box 1, the second direction y is defined as the width direction of the box 1, and the third direction z is defined as the height direction of the box 1. At the same time, the gas flows into the box 1 from one end along the third direction z, flows through the flow guide component 2, and then flows out from the other end of the box 1.

[0068] In this embodiment, since the detection device 3, the drive assembly, and the heating film are electrically or signal-connected to the control system, the heating device can achieve local structural adjustment and local temperature adjustment. That is, the control system can control the drive assembly to drive the guide vanes 211 to rotate independently or stop rotating based on the detection results of the detection device 3, and / or control the heating film to heat independently or stop heating. This is beneficial to improving the flexibility of the heating device and improving the control accuracy of local structure and local temperature, thereby enabling the processing of special parts or maintenance of special instruments in the target area.

[0069] Specifically, when the heating device delivers gas to the target area, if the detection result of the detection device 3 meets the preset conditions, the heating device only needs to drive some of the guide vanes 211 to rotate through the drive component to change the direction and opening of the air delivery channel 212 formed between these guide vanes 211, so that it can be aligned with the target area. In this way, the gas can be accurately guided and covered to the target area without controlling all the guide vanes 211 to rotate, so as to avoid the gas being too dispersed in the process of flowing to the target area due to too many air delivery channels 212.

[0070] More specifically, when the heating device delivers gas to the target area, if the detection result of the detection device 3 does not meet the preset conditions (e.g., the gas temperature is low), the heating device needs to control the heating film of the part of the guide vanes 211 to start while driving the part of the guide vanes 211 to rotate through the drive component, so that it can heat the gas in the air delivery channel 212 formed by the part of the guide vanes 211. In this way, the gas that meets the preset conditions can be accurately guided and covered to the target area, without having to control the entire heating film to start, so as to avoid excessive heating film generating additional heat during operation and causing energy waste.

[0071] Therefore, this design allows the heating device to achieve individual adjustment of its local structure and individual heating of its local temperature, enabling directional gas flow and localized heating for processing special components or maintaining special instruments within the target area. Furthermore, the detection device 3 and control system enable closed-loop control of the heating device for gas temperature detection, adjustment, and heating, thereby shortening response time, improving work efficiency, and facilitating efficient and precise real-time dynamic adjustment of gas temperature, thus enhancing the flexibility of the heating device during operation. Simultaneously, since the multiple guide vanes 211 and heating films are arranged in parallel, the risk of overall device shutdown due to damage to some guide vanes 211 and / or heating films is avoided. Only the damaged components need to be replaced individually, which not only reduces maintenance costs and improves repair efficiency but also enhances the stability and reliability of the heating device during operation. In addition, controlling the localized heating films during heating also helps reduce energy consumption, improve energy utilization, lower the operating costs of the heating device, and better meet practical usage requirements.

[0072] Specifically, the multiple guide vanes 211 of the flow guiding assembly 2 can be distributed at intervals along the first direction x or the second direction y. Along the arrangement direction of the guide vanes 211, there is also a gap between the guide vanes 211 at the edges and the inner wall of the housing 1, so that air supply channels 212 for gas flow can be formed between adjacent guide vanes 211 and between the guide vanes 211 and the inner wall of the housing 1, thereby diverting the gas flow and improving gas flow efficiency. Simultaneously, since each guide vane 211 is equipped with a heating film, the gas can be uniformly heated during its flow within each air supply channel 212, further improving gas heating efficiency.

[0073] Specifically, the drive assembly can be connected to each guide vane 211 so that the guide vanes 211 are arranged in parallel. This allows the drive assembly to drive all or part of the guide vanes 211 to rotate relative to the housing 1, thereby adjusting the extension direction of all or part of the air supply channel 212 and thus adjusting the direction of all or part of the gas flow. For example, when the drive assembly drives some guide vanes 211 to rotate relative to the housing 1, the drive assembly can drive any one guide vane 211 to rotate, or drive at least two adjacent guide vanes 211 to rotate in the same or opposite directions, or drive at least two non-adjacent guide vanes 211 to rotate in the same or opposite directions, in order to meet different usage requirements and improve the flexibility and functional diversity of the guide assembly 2.

[0074] Specifically, the detection device 3 can be disposed on at least one side of the flow guiding component 2 along a third direction z, so that the detection device 3 can detect the temperature on the air inlet side of the flow guiding component 2, so that the control system can directly control the drive component to start or stop, and / or control the heating film to open or close, based on the detection result of the detection device 3, thereby adjusting the gas flow direction and gas temperature; or, the detection device 3 can detect the temperature on the air outlet side of the flow guiding component 2, so that the control system can readjust the working state of the drive component and / or the heating film based on the measurement result of the detection device 3, thereby verifying the gas flow direction and gas temperature.

[0075] In one possible implementation, when the gaps between two adjacent guide vanes 211 and between the edge guide vane 211 and the inner wall of the housing 1 are equal, the flow cross-sectional area of ​​each air supply channel 212 is nearly equal, which is also beneficial to improve the uniformity of gas diversion, thereby improving the uniformity of gas flow to the target area.

[0076] In one possible implementation, the guide vane 211 rotates at an angle β relative to the housing 1, and β satisfies 0°≤β≤180°, specifically it can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165°, 170°, 175°, 180°, etc.

[0077] In one possible implementation, when the heating device is in its initial state, the angle between each guide vane 211 of the flow guiding assembly 2 and the horizontal plane is 0°, that is, the guide vane 211 is parallel to the horizontal plane. Furthermore, when the heating device is in its initial state, there is a gap between adjacent guide vanes 211 along the first direction x or the second direction y, and the gap between adjacent guide vanes 211 is greater than or equal to the width of any guide vane 211 along the third direction z. This avoids the risk of interference when two adjacent guide vanes 211 rotate relative to each other, thereby improving the safety and reliability of the heating device during operation.

[0078] In one possible implementation, when the control system controls the drive assembly to drive the guide vanes 211 to rotate relative to the housing 1, the control system can control the heating film of the rotated guide vanes 211 to start, or control the heating film of the unrotated guide vanes 211 to start, so that the operator can make adjustments according to the needs during actual use, which is beneficial to further improve the flexibility of the heating device.

[0079] In one possible implementation, such as Figure 2 , Figure 3 and Figure 4 As shown, the projection of the guide vane 211 along the third direction z is either straight or curved. This design allows each air supply channel 212 to have a rectangular or curved cross-section, meeting the different needs of the heating device in the target area for processing special components or maintaining special equipment, and improving the functional versatility of the guide assembly 2.

[0080] In one specific implementation, such as Figure 3 As shown, the guide vanes 211 extend along the first direction x and are spaced apart along the second direction y. The guide assembly 2 also includes a connecting plate 213, which is distributed on both sides of the guide vanes 211 along the first direction x and is used to connect at least two adjacent guide vanes 211 to form a guide vane group 21. The drive assembly is connected to the guide vanes 211 through the connecting plate 213.

[0081] In this embodiment of the application, when at least two adjacent guide vanes 211 are connected by a connecting plate 213 to form a guide vane group 21 along the arrangement direction of the guide vanes 211, the stability and reliability of the connection between adjacent guide vanes 211 can be improved, thereby improving the structural stability of the guide vane group 21. This ensures that the air supply channel 212 inside the guide vane group 21 also has good structural stability, which helps to reduce the possibility of deformation of the internal air supply channel 212 due to gas impact or temperature stress, and improves the stability of the gas during the flow process.

[0082] The drive assembly can simultaneously control at least two guide vanes 211 to rotate synchronously via the connecting plate 213. This helps to improve the consistency of at least two adjacent guide vanes 211 during rotation. When gas flows within the internal air supply channel 212, it can form an air curtain with a unified flow direction, thus avoiding the risk of gas dispersion due to angular deviation of a single guide vane 211. This improves the accuracy of directional gas flow, thereby further enhancing the precision of local control of the guide assembly 2 by the heating device.

[0083] Meanwhile, since the drive assembly can drive at least two adjacent guide vanes 211 through the connecting plate 213, it is not necessary to set a corresponding drive component for each guide vane 211. This simplifies the drive method, reduces the design difficulty of the control system, and thus reduces the number of components in the drive assembly, lowers the production cost of the heating device, and improves the space utilization inside the housing 1. This makes the internal layout of the heating device more compact, so as to achieve the goal of miniaturization of the heating device.

[0084] In addition, along the arrangement direction of the guide vanes 211, air supply channels 212 for gas flow can also be formed between two adjacent guide vane groups 21 and between the guide vane group 21 located at the edge and the inner wall of the housing 1, which is conducive to further improving the gas flow efficiency.

[0085] In one specific implementation, such as Figure 3 As shown, the guide vane 211 includes a first vane 211a and a second vane 211b. The first vane 211a and the second vane 211b are alternately arranged along the second direction y. The width of the first vane 211a is L1, and the width of the second vane 211b is L2. L1 and L2 satisfy 0.25≤L1 / L2≤1.

[0086] In this embodiment of the application, when the first blade 211a and the second blade 211b are alternately arranged and spaced apart along the second direction y, the connecting plate 213 can connect two adjacent first blades 211a and second blades 211b along the second direction y to form a guide blade group 21 that facilitates the inclined transmission of gas.

[0087] Specifically, when gas flows through the air supply channel 212 inside the guide vane assembly 21, due to the size difference between the first blade 211a and the second blade 211b, the gas can form an air curtain in the internal air supply channel 212 with a uniform flow direction and biased towards the first blade 211a. This improves the accuracy of the gas's directional flow towards the side closer to the first blade 211a, thereby optimizing the stability of the gas during the flow process and achieving a better delivery effect.

[0088] More specifically, the width ratio L1 / L2 of the first blade 211a and the second blade 211b can be 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, etc.

[0089] When the width ratio of the first blade 211a and the second blade 211b is too small (e.g., L1 / L2 is less than 0.25), there is an excessive size difference between the first blade 211a and the second blade 211b, which makes it impossible to effectively concentrate the gas during the flow process, and there is a possibility of dispersion. As a result, the final coverage area of ​​the gas is larger than the target area. This not only makes the guide vane group 21 have poor precision control over gas guidance, but also easily causes some gas to be wasted.

[0090] Therefore, when the width ratio of the first blade 211a and the second blade 211b satisfies 0.25≤L1 / L2≤1, the size difference between the first blade 211a and the second blade 211b is moderate, so that when the gas flows through the air supply channel 212 inside the guide blade group 21, it can be accurately guided to the target area, and the gas flow direction is more likely to be biased towards the side of the shorter first blade 211a. Thus, while ensuring the gas guiding effect, the stability of the gas during the inclined transmission process can be optimized to achieve a better delivery effect, thereby ensuring the gas processing effect on special components or the maintenance effect on special equipment in the target area.

[0091] It should be noted that the arrangement of the first blade 211a and the second blade 211b can be adjusted according to requirements to meet the needs of the guide vane group 21 to tilt and transport the gas in different directions.

[0092] In one specific implementation, such as Figure 2 , Figure 3 and Figure 4 As shown, the guide vane 211 or the connecting plate 213 is provided with a rotating shaft 214. The drive assembly includes a drive motor (not shown in the figure) and a transmission gear set (not shown in the figure). The drive motor is connected to the rotating shaft 214 through the transmission gear set so that at least one guide vane 211 rotates relative to the housing 1.

[0093] In this embodiment, the drive motor can be connected to the rotating shaft 214 via a transmission gear set to drive the guide vane 211 or the connecting plate 213 to rotate relative to the housing 1, thereby achieving overall or partial adjustment of the guide assembly 2. Gear transmission is simple in structure and easy to implement, which helps improve the stability and reliability of the guide vane 211 or the connecting plate 213 during rotation. Simultaneously, it also improves the control precision of the guide vane 211 or the connecting plate 213, enabling them to rotate to a preset angle to meet the requirements of the guide assembly 2 for gas transmission at any angle, thus enhancing the flexibility and functional versatility of the guide assembly 2.

[0094] In one specific implementation, such as Figure 5 As shown, the flow guiding assembly 2 includes a first flow guiding group 22 and a second flow guiding group 23. The first flow guiding group 22 and the second flow guiding group 23 are distributed at intervals along the third direction z. The projection of any flow guiding blade 211 in the first flow guiding group 22 and the projection of any flow guiding blade 211 in the second flow guiding group 23 have a first included angle α, and satisfy 0°<α≤90°.

[0095] In this embodiment of the application, both the first guide group 22 and the second guide group 23 include a plurality of guide vanes 211 spaced apart. The guide vanes 211 in the first guide group 22 can extend along the second direction y and are spaced apart along the first direction x. The guide vanes 211 in the second guide group 23 can extend along the first direction x and are spaced apart along the second direction y. This design allows the projection of any guide vane 211 in the first guide group 22 to intersect with the projection of any guide vane 211 in the second guide group 23, forming a first included angle α. This enables the guide assembly 2 to transmit gas along the first direction x towards one or both sides, and also along the second direction y towards one or both sides. When the guide vane 211 of the first guide group 22 (or the second guide group 23) is tilted relative to the vertical plane, the guide vane 211 of the second guide group 23 (or the first guide group 22) needs to be rotated to a position parallel to the vertical plane, so that the air supply channels 212 of the first guide group 22 and the second guide group 23 are interconnected. This facilitates the flow of gas out of the guide assembly 2, improves the stability and smoothness of the gas flow, and further enhances the flexibility and functional versatility of the guide assembly 2 to meet the needs of the guide assembly 2 for transmitting gas at any angle.

[0096] Specifically, when the flow guiding assembly 2 needs to transmit gas to one side along the first direction x, the control system controls the drive assembly to drive all the flow guiding blades 211 of the first flow guiding group 22 to rotate to the left or right by a preset angle, and controls the drive assembly to drive all the flow guiding blades 211 of the second flow guiding group 23 to rotate to be perpendicular to the horizontal plane; when the flow guiding assembly 2 needs to transmit gas to both sides along the first direction x, the control system controls the drive assembly to drive a portion of the flow guiding blades 211 of the first flow guiding group 22 to rotate to the left by a preset angle, and another portion of the flow guiding blades 211 of the first flow guiding group 22 to rotate to the right by a preset angle, and controls the drive assembly to drive all the flow guiding blades 211 of the second flow guiding group 23 to rotate to be perpendicular to the horizontal plane.

[0097] Specifically, when the flow guiding assembly 2 needs to transmit gas to one side along the second direction y, the control system controls the drive assembly to drive all the flow guiding blades 211 of the first flow guiding group 22 to rotate to be perpendicular to the horizontal plane, and controls the drive assembly to drive all the flow guiding blades 211 of the second flow guiding group 23 to rotate forward or backward by a preset angle; when the flow guiding assembly 2 needs to transmit gas to both sides along the first direction x, the control system controls the drive assembly to drive all the flow guiding blades 211 of the first flow guiding group 22 to rotate to be perpendicular to the horizontal plane, and controls the drive assembly to drive a portion of the flow guiding blades 211 of the second flow guiding group 23 to rotate forward by a preset angle, and another portion of the flow guiding blades 211 of the second flow guiding group 23 to rotate backward by a preset angle.

[0098] Specifically, the first included angle α can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc.

[0099] In one specific embodiment, the area of ​​the guide vane 211 is S1, the area of ​​the heating film is S2, and S1 and S2 satisfy 0.1≤S2 / S1≤1.

[0100] In this embodiment of the application, the area ratio S2 / S1 of the guide vane 211 and the heating film can specifically be 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1, etc.

[0101] When the area ratio of the guide vane 211 to the heating film is too small (e.g., S2 / S1 is less than 0.1), the coverage area of ​​the heating film is too small, which means that the heating film cannot fully heat the gas during the flow of gas in the air supply channel 212, resulting in poor heating effect and failing to meet the processing requirements of special components or the maintenance requirements of special instruments in the target area.

[0102] Therefore, when the area ratio of the guide vane 211 to the heating film satisfies 0.1≤S2 / S1≤1, the coverage area of ​​the heating film is moderate or even large, so as to effectively heat the gas during the gas flow and ensure the uniformity of the gas temperature after heating. This avoids the risk of localized high or low temperatures after the gas flows out of the air supply channel 212, thus ensuring the reliability of processing special components or maintaining special equipment within the target area. Simultaneously, since the coverage area of ​​the heating film matches the contact area with the gas, ineffective heat dissipation can be reduced, which is beneficial to improving energy utilization and reducing the operating cost of the heating device.

[0103] In one specific embodiment, the heating film includes an electric heating layer (not shown in the figure) and an insulating layer (not shown in the figure). The insulating layer covers both sides of the electric heating layer. The electric heating layer is electrically connected to a heating power source (not shown in the figure). The heating power source is electrically connected or signal connected to a control system. The control system can also control the power of the heating power source to increase or decrease according to the detection result of the detection device 3.

[0104] In this embodiment, since the electric heating layer of the heating film is electrically connected to the heating power supply, and the heating power supply is electrically connected or signal connected to the control system, the opening or closing of the heating power supply can directly affect the working state of the heating film. Thus, the control system can control the opening or closing of the heating film and the increase or decrease of the heating power of the heating film based on the detection results of the detection device 3.

[0105] This design allows the heating film to heat the gas within the air supply channel 212 via electric heating, enabling rapid temperature rise of the heating film and improving both its heating efficiency and the gas's overall heating efficiency. Simultaneously, the control system's regulation of the heating power supply enhances the precision of temperature control, meeting the demands of precision machining processes. This improves the safety and reliability of the heating device during the processing of special components or the maintenance of specialized equipment within the target area. Furthermore, it accelerates the response efficiency of the electric heating layer and shortens the temperature regulation lag time, further enhancing the dynamic response capability and control precision of the control system.

[0106] By covering both sides of the electric heating layer with an insulating layer, the electric heating layer can be completely wrapped, reducing the possibility of leakage or short circuit during operation. This improves the safety and reliability of the heating device during operation, resulting in good working stability and extending its service life.

[0107] In one possible implementation, the electric heating layer is made of graphene composite material, and the thickness of the electric heating layer is H1, satisfying 10μm≤H1≤100μm.

[0108] In this embodiment, when the material of the electric heating layer is graphene composite material, the low resistivity and high thermal conductivity can ensure that the electric heating layer has good electrothermal conversion efficiency, thereby enabling the heating film to heat up quickly and improving the heating efficiency of the gas.

[0109] Specifically, when the material of the electric heating layer is graphene composite material, the thickness H1 of the electric heating layer can be 10μm, 15μm, 20μm, 25μm, 30μm, 35μm, 40μm, 45μm, 50μm, 55μm, 60μm, 65μm, 70μm, 75μm, 80μm, 85μm, 90μm, 95μm, 100μm, etc.

[0110] In one possible implementation, the electric heating layer is made of nickel-chromium alloy or iron-chromium-aluminum alloy, and the thickness of the electric heating layer is H2, satisfying 30μm≤H2≤3000μm.

[0111] In this embodiment, when the electric heating layer is made of nickel-chromium alloy or iron-chromium-aluminum alloy, it can maintain high stability at high temperatures, which is beneficial to improving the safety and stability of the heating film during operation. Furthermore, the surface of the electric heating layer also has an oxide film, giving it good anti-oxidation properties and extending the service life of the heating film.

[0112] Specifically, when the material of the electric heating layer is a nickel-chromium alloy or an iron-chromium-aluminum alloy, the thickness H2 of the electric heating layer can be 30μm, 130μm, 230μm, 330μm, 430μm, 530μm, 630μm, 730μm, 830μm, 930μm, 1000μm, 1100μm, 1200μm, 1300μm, 1400μm, 1500μm, 1600μm, 1700μm, 1800μm, 1900μm, 2000μm, 2100μm, 2200μm, 2300μm, 2400μm, 2500μm, 2600μm, 2700μm, 2800μm, 2900μm, 3000μm, etc.

[0113] In one possible implementation, the thickness of the insulating layer is H3, and satisfies 50μm≤H3≤300μm.

[0114] In this embodiment, the thickness H3 of the insulating layer can be 50μm, 60μm, 70μm, 80μm, 90μm, 100μm, 110μm, 120μm, 130μm, 140μm, 150μm, 160μm, 170μm, 180μm, 190μm, 200μm, 210μm, 220μm, 230μm, 240μm, 250μm, 260μm, 270μm, 280μm, 290μm, 300μm, etc.

[0115] Therefore, when the thickness of the insulating layer meets the requirement of 50μm≤H3≤300μm, the insulating layer is not easily broken down during the operation of the heating film, thus ensuring the working stability of the heating film. In addition, the insulating layer can transfer heat to the gas in a timely manner, which is beneficial to improving the heat transfer efficiency and thus ensuring the heating efficiency of the heating film on the gas.

[0116] In one specific implementation, such as Figure 6 As shown, the heating device also includes a first flow equalization plate 4, which is installed inside the housing 1 and located on the air inlet side of the flow guiding component 2. The first flow equalization plate 4 is provided with a plurality of first through holes 41, which are distributed at intervals along the first direction x and the second direction y, and each first through hole 41 is connected to the inlet end of the air supply channel 212.

[0117] In this embodiment, by setting the first flow equalization plate 4 on the air inlet side of the flow guiding component 2, the gas is first divided by the first flow equalization plate 4 during the flow process, and then flows into each air supply channel 212 and is guided by the flow guide blades 211 and / or heated by the heating film to be transmitted to the target area, thereby realizing the directional flow and local heating of the gas.

[0118] The first flow equalization plate 4 is provided with a plurality of first through holes 41 spaced apart along the first direction x and the second direction y, so that the first flow equalization plate 4 can divide the gas through the array of first through holes 41, thereby reducing the possibility of uneven distribution of flow velocity and / or flow rate after the gas flows into the heating device, improving the uniformity of the gas before flowing into the flow guide assembly 2, and ensuring that the conditions are consistent when the gas flows into each air supply channel 212, so as to make precise adjustments to the local parts of the flow guide assembly 2 (e.g., controlling the rotation of some flow guide blades 211, and / or controlling the activation of some heating film), which is beneficial to further improve the control accuracy of the control system on the flow guide blades 211 and / or heating film.

[0119] Meanwhile, after the first flow equalization plate 4 evenly distributes the gas, it can also reduce the error of the gas temperature measurement by the detection device 3, thereby improving the accuracy of the detection results. This can prevent the control system from controlling too many or too few heating films to continue adjusting the gas temperature, thereby improving the effective utilization rate of energy, reducing ineffective energy consumption, and reducing the operating cost of the heating device.

[0120] In addition, after the first flow equalization plate 4 evenly distributes the gas, it can also improve the stability of the gas flow, thereby reducing the possibility of noise or fluctuations caused by gas impact on the flow guiding component 2, which is conducive to improving the safety and reliability of the flow guiding component 2 during operation.

[0121] Therefore, when the first flow equalization plate 4 is disposed on the air inlet side of the flow guiding component 2 along the third direction z, the first through hole 41 can improve the flow state of the gas in the box 1, and can also ensure the stability and reliability of the subsequent detection device 3 and control system during operation, thereby improving the synergistic working ability between the local flow guiding component and the local heating film, and thus improving the overall working performance of the heating device.

[0122] In one possible implementation, when the projection of the first flow equalization plate 4 (or the second flow equalization plate 5) along the third direction z is a rectangular structure, the first through hole 41 (or the second through hole 51) can be arranged in a rectangular array on the first flow equalization plate 4 (or the second flow equalization plate 5); when the projection of the first flow equalization plate 4 (or the second flow equalization plate 5) along the third direction z is circular, the first through hole 41 (or the second through hole 51) can be arranged in a circular array on the first flow equalization plate 4 (or the second flow equalization plate 5).

[0123] In one specific implementation, such as Figure 6 As shown, the heating device also includes a second flow equalization plate 5, which is installed inside the housing 1 and located on the air outlet side of the flow guiding component 2. The second flow equalization plate 5 is provided with a plurality of second through holes 51, which are distributed at intervals along the first direction x and the second direction y, and each second through hole 51 is connected to the outlet end of the air supply channel 212.

[0124] In this embodiment, by setting the second flow equalization plate 5 on the air outlet side of the flow guiding component 2, the gas first flows into each air supply channel 212 and is guided by the flow guide blades 211 and / or heated by the heating film during the flow process, and then is diverted by the second flow equalization plate 5 to transmit it to the target area, thereby realizing the directional flow and local heating of the gas.

[0125] The second flow equalization plate 5 is provided with a plurality of second through holes 51 spaced apart along the first direction x and the second direction y, so that the second flow equalization plate 5 can perform secondary flow division of gas through the array of second through holes 51, which is used to reduce the possibility of high and low temperature stratification caused by uneven temperature distribution after the gas is heated, and to force the mixing of airflows with different temperatures and / or different flow rates, so as to improve the uniformity of gas flow when it exits the heating device, so as to meet the requirements of air conditioning for processing or maintenance of special components or special instruments in the target area.

[0126] Meanwhile, after the second flow equalization plate 5 evenly distributes the gas, it can also directly reflect the temperature of the gas after it flows out of the flow guide component 2, and provide real and effective feedback to the control system so that the control system can adjust the working state of the flow guide blade 211 and / or the heating film, which is beneficial to improving the dynamic response capability and control accuracy of the control system.

[0127] In addition, since the second flow equalization plate 5 is located on the air outlet side of the flow guide assembly 2, the second through hole 51 of the second flow equalization plate 5 can serve as the air outlet of the heating device, so as to avoid the risk of the external environment affecting the gas flowing out from the flow guide assembly 2, and ensure that the gas can flow out of the heating device under the guidance of the flow guide blade 211, so that it can flow accurately to the target area.

[0128] Therefore, when the second flow equalization plate 5 is disposed on the air outlet side of the flow guide component 2 along the third direction z, the second through hole 51 can improve the flow state when the gas flows out of the flow guide component 2, and can also provide feedback on the gas treatment effect of the flow guide component 2, so that the control system can readjust the working state of the flow guide blade 211 and / or the heating film, thereby improving the cooperative working ability between the local flow guide component and the local heating film, and thus improving the overall working performance of the heating device.

[0129] In one possible implementation, the heating device can be provided with either the first flow equalization plate 4 or the second flow equalization plate 5 separately, or it can be provided with both the first flow equalization plate 4 and the second flow equalization plate 5 simultaneously.

[0130] In this embodiment of the application, when the heating device is simultaneously provided with a first flow equalization plate 4 and a second flow equalization plate 5, the first flow equalization plate 4 and the second flow equalization plate 5 are located on the air inlet side and air outlet side of the flow guiding component 2 along the third direction z, respectively, and are used to uniformly divide the gas flowing into and out of the heating device to form a symmetrically distributed airflow shaping architecture, ensuring the uniformity of flow rate and temperature when the gas enters and exits, and realizing the high-precision control capability of the air conditioner.

[0131] In one possible implementation, along the third direction z, when the angle of the guide vane 211 is fixed, the angle of the air supply channel 212 is fixed. At this time, the first through hole 41 and / or the second through hole 51 can be arranged in parallel with the air supply channel 212, which is beneficial to further optimize the smoothness and stability of the gas flow process.

[0132] In one specific implementation, such as Figure 6 As shown, the detection device 3 includes multiple detection elements. When the heating device includes a first flow equalization plate 4, the multiple detection elements are distributed at intervals along the first direction x and the second direction y on the first flow equalization plate 4, and the detection elements are arranged adjacent to the first through hole 41 for detecting the gas temperature inside the first through hole 41. When the heating device includes only a second flow equalization plate 5 or includes both the first flow equalization plate 4 and the second flow equalization plate 5, the multiple detection elements are distributed at intervals along the first direction x and the second direction y on the second flow equalization plate 5, and the detection elements are arranged adjacent to the second through hole 51 for detecting the gas temperature inside the second through hole 51.

[0133] In this embodiment of the application, the detection device 3 may include a plurality of first detection elements 31 or a plurality of second detection elements 32.

[0134] Specifically, when the heating device includes a first flow equalization plate 4, multiple first detection elements 31 are distributed at intervals along the first direction x and the second direction y on the first flow equalization plate 4, and each first detection element 31 is arranged adjacent to each first through hole 41 to detect the gas temperature in the adjacent first through hole 41, so as to improve the detection accuracy of the first detection element 31. This allows the control system to control the drive assembly to drive the partial guide vane 211 to rotate and / or control the partial heating film to heat according to the detection results of the first detection element 31, thereby enabling the heating device to process special parts or maintain special instruments in the target area.

[0135] When the first detection element 31 is set on the air inlet side of the flow guide component 2, the first detection element 31 can directly detect the temperature of the gas, which helps to reduce the error of the gas temperature measurement by the detection device 3, thereby improving the accuracy of the detection results. This avoids the control system from controlling too much or too little heating film to continue adjusting the gas temperature, thereby improving the effective utilization rate of energy, reducing ineffective energy consumption, and reducing the operating cost of the heating device.

[0136] Simultaneously, the projections of each first detection element 31 and each first through hole 41 along the first direction x and the second direction y can be staggered, so that the first detection element 31 is diagonally distributed relative to the first through hole 41, enabling the first detection element 31 to detect the gas temperature within at least four of its surrounding first through holes 41. This design allows the first detection element 31 to detect the gas temperature within a local area of ​​the first flow equalization plate 4, reducing the number of first detection elements 31 used, lowering production costs, and thus reducing the number of reference results. This, in turn, reduces the difficulty of subsequent processing, calculation, and judgment in the control system, improving the response efficiency of the control system.

[0137] In other embodiments, the first detection element 31 may also be disposed within the first through hole 41 to further improve the accuracy of the detection results.

[0138] Specifically, when the heating device includes only the second flow equalization plate 5 or includes both the first flow equalization plate 4 and the second flow equalization plate 5, multiple second detection elements 32 are distributed at intervals along the first direction x and the second direction y on the second flow equalization plate 5, and each second detection element 32 is arranged adjacent to each second through hole 51 to detect the gas temperature in the adjacent second through hole 51, so as to improve the detection accuracy of the second detection element 32, so that the control system can control the drive assembly to drive the partial guide vane 211 to rotate and / or control the partial heating film to heat according to the detection results of the second detection element 32, thereby realizing the processing of special parts or maintenance of special instruments in the target area by the heating device.

[0139] When the second detection element 32 is set on the air outlet side of the flow guide component 2, there is no need to set the first detection element 31 on the air inlet side of the flow guide component 2. The second detection element 32 can directly reflect the temperature of the gas after it flows out of the flow guide component 2 and can provide real and effective feedback to the control system so that the control system can adjust the working state of the flow guide blade 211 and / or the heating film. This is beneficial to improving the dynamic response capability and control accuracy of the control system and reducing the production cost of the heating device.

[0140] Simultaneously, the projections of each second detection element 32 and each second through hole 51 along the first direction x and the second direction y can be staggered, so that the second detection element 32 is diagonally distributed relative to the second through hole 51, enabling the second detection element 32 to detect the gas temperature within at least four of its surrounding second through holes 51. This design allows the second detection element 32 to detect the gas temperature within a localized area of ​​the second flow equalization plate 5, reducing the number of second detection elements 32 used, lowering production costs, and consequently reducing the number of reference results. This reduces the difficulty of subsequent processing, calculation, and judgment in the control system, thus improving the response efficiency of the control system.

[0141] In other embodiments, the second detection element 32 may also be disposed within the second through hole 51 to further improve the accuracy of the detection results.

[0142] Therefore, by setting the detection device 3 on the first flow equalization plate 4 or the second flow equalization plate 5, a closed-loop control method for the detection, adjustment and heating of gas temperature by the heating device can be realized, thereby shortening the response time, improving work efficiency, facilitating efficient and accurate real-time dynamic adjustment of gas temperature, improving the flexibility of the heating device in the working process, and better meeting the actual use needs.

[0143] Embodiments of this application also provide a control method for a heating device, wherein the heating device is any of the heating devices described above, used to transfer gas to a target area to enable air conditioning for processing special components or maintaining special equipment, and the preset temperature of the target area is T0. The control method includes:

[0144] The system detects either the first gas temperature T1 on the air inlet side of the air guide assembly 2 or the second gas temperature T2 on the air outlet side of the air guide assembly 2. When T0 and T1 satisfy T0 > T1 or T0 and T2 satisfy T0 > T2, the system controls the drive assembly to drive at least one guide vane 211 to rotate so that the air supply channel 212 is aligned with the target area, and controls the heating film to be in the open state to heat the gas in the air supply channel 212. When T0 and T1 satisfy T0 ≤ T1 or T0 and T2 satisfy T0 ≤ T2, the system controls the drive assembly to drive at least one guide vane 211 to rotate so that the air supply channel 212 is aligned with the target area, and controls the heating film to be in the closed state.

[0145] In this embodiment, when the heating device includes a first flow equalization plate 4, the first flow equalization plate 4 is provided with a first detection element 31 for detecting the gas temperature in adjacent first through holes 41, so that the control system can control the drive assembly to drive the partial guide vanes 211 to rotate and / or control the partial heating film to heat according to the detection result of the first detection element 31. Alternatively, when the heating device includes only a second flow equalization plate 5 or includes both a first flow equalization plate 4 and a second flow equalization plate 5, the second flow equalization plate 5 is provided with a second detection element 32 for detecting the gas temperature in adjacent second through holes 51, so that the control system can control the drive assembly to drive the partial guide vanes 211 to rotate and / or control the partial heating film to heat according to the detection result of the second detection element 32, thereby enabling the heating device to process special components or maintain special instruments in the target area.

[0146] Specifically, since the first detection element 31 is located on the air inlet side of the flow guiding component 2, the first detection element 31 can directly detect the temperature of the gas, which helps to reduce the error of the gas temperature measurement by the detection device 3, thereby improving the accuracy of the detection results. This avoids the control system from controlling too many or too few heating films to continue adjusting the gas temperature, thereby improving the effective utilization rate of energy, reducing ineffective energy consumption, and reducing the operating cost of the heating device.

[0147] Specifically, since the second detection element 32 is located on the air outlet side of the flow guide assembly 2, the second detection element 32 can directly reflect the temperature of the gas after it flows out of the flow guide assembly 2, and can provide real and effective feedback to the control system so that the control system can adjust the working state of the flow guide blade 211 and / or the heating film, which is beneficial to improving the dynamic response capability and control accuracy of the control system.

[0148] More specifically, when T0 and T1 satisfy T0 > T1, the temperature of the gas flowing into the heating device is lower than the preset temperature of the target area. At this time, the control system can control the drive assembly to drive at least one guide vane 211 to rotate according to a preset program, so that the air supply channel 212 is aligned with the target area, and control the heating film to be in the open state to heat the gas in the air supply channel 212, so that the temperature of the gas flowing out of the heating device can reach the preset temperature of the target area, thereby ensuring the stability and reliability of the air conditioner during operation.

[0149] More specifically, when T0 and T2 satisfy T0 > T2, the temperature of the gas flowing out of the heating device is less than the preset temperature of the target area. At this time, the control system can control the drive assembly to drive at least one guide vane 211 to rotate according to the preset program, so that the air supply channel 212 is aligned with the target area, and control the heating film to be in the open state to heat the gas in the air supply channel 212 until T0 and T2 satisfy T0 ≤ T2. At this time, the control system can control the drive assembly to drive that part of the guide vane 211 to stop rotating according to the preset program, so as to fix the air supply channel 212 and improve the accuracy of the gas flow to the target area. At the same time, the control system can also control the heating power of the heating film to remain constant according to the preset program, so as to continuously heat the gas in the air supply channel 212, thereby ensuring that the temperature of the gas flowing out of the heating device is equal to the preset temperature of the target area, thus ensuring the stability and reliability of the air conditioner during operation.

[0150] More specifically, when T0 and T1 satisfy T0≤T1, the temperature of the gas flowing into the heating device is equal to or even greater than the preset temperature of the target area. At this time, the control system can control the drive assembly to rotate at least one guide vane 211 according to a preset program, so that the air supply channel 212 is aligned with the target area, and control the guide vane 211 to stop rotating, thereby fixing the air supply channel 212 and improving the accuracy of gas flow to the target area. Simultaneously, the control system controls the heating film to be in a closed state, preventing the heating film from reheating the gas flowing into the heating device, allowing the gas flowing into the heating device to directly reach the target area through the guide assembly 2, thus ensuring the stability and reliability of the air conditioner during operation.

[0151] More specifically, when T0 and T2 satisfy T0≤T2, the temperature of the gas flowing out of the heating device is equal to or even greater than the preset temperature of the target area. At this time, the control system can control the drive assembly to rotate at least one guide vane 211 according to a preset program, so that the air supply channel 212 is aligned with the target area, and control the guide vane 211 to stop rotating, thereby fixing the air supply channel 212 and improving the accuracy of gas flow to the target area. Simultaneously, the control system controls the heating film to be in a closed state, preventing the heating film from reheating the gas flowing into the heating device, allowing the gas flowing into the heating device to directly reach the target area through the guide assembly 2, thus ensuring the stability and reliability of the air conditioner during operation.

[0152] Therefore, this design allows the control system to adjust the operating status of the guide assembly 2 and / or the heating film in a timely manner based on the temperature of the gas flowing into or out of the heating device, in order to meet the processing of special components or the maintenance of special instruments within the target area. The real-time detection of gas temperature by the detection device 3 helps to shorten the response time and improve work efficiency, enabling the control system to achieve efficient and accurate real-time dynamic adjustment of the gas temperature, further enhancing the flexibility of the heating device during operation.

[0153] In one specific embodiment, the initial heating power of the heating power supply is P0. During the process of controlling the drive assembly to drive at least one guide vane 211 to rotate, so that the air delivery channel 212 is aligned with the target area, and controlling the heating film to be in an open state to heat the gas within the air delivery channel 212, the control method further includes:

[0154] The power of the heating power supply is controlled to be at the first heating power P1, and P0 and P1 satisfy P0 < P1.

[0155] In this embodiment, the control system can control the increase or decrease of the heating power of the heating film based on the detection results of the detection device 3, so that the heating film can heat the gas in the air supply channel 212 by electric heating, thereby achieving rapid heating of the heating film and improving the heating efficiency of the heating film and the heating efficiency of the gas. At the same time, by controlling the heating power supply through the control system, it is beneficial to further improve the control accuracy of the heating temperature to meet the process requirements of precision machining, thereby improving the safety and reliability of the heating device in the target area for processing special parts or maintaining special instruments.

[0156] Specifically, when T0 and T1 satisfy T0 > T1, the temperature of the gas flowing into the heating device is lower than the preset temperature of the target area. At this time, the control system can control the heating film to be in the open state according to the preset program, and control the power of the heating power supply to increase from the initial power to the first heating power, so as to further improve the heating efficiency of the heating film and the heating efficiency of the gas, thereby enabling the temperature of the gas flowing out of the heating device to reach the preset temperature of the target area, so as to ensure the stability and reliability of the air conditioner during operation.

[0157] Specifically, when T0 and T2 satisfy T0 > T2, the temperature of the gas flowing out of the heating device is lower than the preset temperature of the target area. At this time, the control system can control the heating film to be in the open state according to a preset program, and control the power of the heating power supply to increase from the initial power to the first heating power, thereby further improving the heating efficiency of the heating film and the heating efficiency of the gas. This ensures that the temperature of the gas flowing out of the heating device reaches the preset temperature of the target area, thus guaranteeing the stability and reliability of the air conditioner during operation. Simultaneously, when T0 and T2 satisfy T0 ≤ T2, the control system can control the heating power of the heating film to always remain at the first heating power according to a preset program, ensuring that the heating film can continuously heat the gas in the air supply channel 212 with a stable heating power. This ensures that the temperature of the gas flowing out of the heating device remains equal to the preset temperature of the target area, thereby guaranteeing the stability and reliability of the air conditioner during operation.
