[0059] For a better understanding of the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0060] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0061] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "an" and "the" used in the embodiments of the present 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 herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0063] The embodiments of the present application provide a heating device, as shown in Figure 1 , Figure 2 and Figure 6 The heating device comprises a box body 1, a flow guide assembly 2, a driving assembly (not marked in the figure) and a detection device 3, and the flow guide assembly 2, the driving assembly and the detection device 3 are all installed in the box body 1.

[0064] Among them, the flow guide assembly 2 comprises a plurality of flow guide vanes 211, the plurality of flow guide vanes 211 are distributed at intervals, a blowing passage 212 is formed between adjacent flow guide vanes 211, each flow guide vane 211 is provided with a heating film (not shown in the figure) for heating the gas in the blowing passage 212. The driving assembly is directly or indirectly connected with each flow guide vane 211, and is used for driving at least one flow guide vane 211 to rotate relative to the box body 1. The detection device 3 is located at the air inlet side or the air outlet side of the flow guide assembly 2, and is used for detecting the temperature of the gas at the air inlet side or the air outlet side of the flow guide assembly 2.

[0065] Meanwhile, the detection device 3, the driving assembly and the heating film are respectively electrically connected or signal connected with a control system (not shown in the figure), and the control system can control the driving assembly to start or stop according to the detection result of the detection device 3, and / or control the heating film to open or close.

[0066] In addition, the heating device can be applied to an industrial precision air conditioner, so that it can be applied to a working scene with strict requirements on environmental parameters such as temperature and gas distribution.

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

[0068] In the embodiments of the present application, since the detection device 3, the driving assembly and the heating film are respectively electrically connected or signal connected with the control system, the heating device can realize local structure adjustment and local temperature adjustment, that is, the control system can control the driving assembly to drive part of the flow guide blades 211 to rotate or stop rotating according to the detection result of the detection device 3, and / or control part of the heating film to heat or stop heating, which is beneficial to improve the flexibility of the heating device, improve the control precision of the local structure and the local temperature, and thus realize the processing of special components or the 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 condition, the heating device only needs to drive part of the flow guide blades 211 to rotate through the driving assembly to change the direction and opening of the air supply channel 212 formed between the part of the flow guide blades 211, so that it can be aligned with the target area, so that the gas can be accurately guided and covered to the target area, and thus it is not necessary to control all the flow guide blades 211 to rotate to avoid too many air supply channels 212 causing the gas to be too dispersed in the process of flowing to the target area.

[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 condition (for example, the gas temperature is relatively low), the heating device needs to drive part of the flow guide blades 211 to rotate through the driving assembly at the same time, and control the heating film of the part of the flow guide blades 211 to start, so that it can heat the gas in the air supply channel 212 formed by the part of the flow guide blades 211, so that the gas meeting the preset condition can be accurately guided and covered to the target area, and thus it is not necessary to control all the heating films to start to avoid too many heating films generating additional heat in the working process, causing energy waste.

[0071] Therefore, by means of the design, the heating device can realize the separate adjustment of the local structure and the separate heating of the local temperature, so as to realize the directional flow and local heating of the gas, so as to process special components or maintain special instruments in the target area. Among them, the detection device 3 and the control system can realize the closed-loop control mode of the detection, adjustment and heating of the heating device to the gas temperature, thereby shortening the response time, improving the work efficiency, and being beneficial to realize the efficient and accurate real-time dynamic adjustment of the gas temperature, and improving the flexibility of the heating device in the working process. At the same time, since the plurality of guide vanes 211 and the plurality of heating films are arranged in parallel, the risk of the whole heating device stopping due to the damage of part of the guide vanes 211 and / or part of the heating films is avoided, and then only the damaged parts need to be replaced, which is not only beneficial to reduce the maintenance cost and improve the maintenance efficiency, but also beneficial to improve the stability and reliability of the heating device in the working process. In addition, in the process of controlling the local heating film to heat, it is also beneficial to reduce energy consumption, improve energy utilization, reduce the operating cost of the heating device, and better meet the actual use demand.

[0072] Specifically, the plurality of guide vanes 211 of the guide assembly 2 can be spaced apart along the first direction x or the second direction y, and along the arrangement direction of the guide vanes 211, the guide vanes 211 located at the edge also have a gap between the inner wall of the box 1, so that the adjacent two guide vanes 211 and the guide vanes 211 and the inner wall of the box 1 can form a gas supply channel 212 for circulating gas, so as to split the gas and improve the flow efficiency of the gas. At the same time, since each guide vane 211 is provided with a heating film, the gas flowing in each supply channel 212 can also be uniformly heated, which is beneficial to improve the heating efficiency of the gas.

[0073] Specifically, the driving assembly can be connected with each guide vane 211, so that each guide vane 211 is arranged in parallel, so that the driving assembly can drive all or part of the guide vanes 211 to rotate relative to the box 1, so as to realize the adjustment of the extension direction of all or part of the gas supply channels 212, and then realize the adjustment of the flow direction of all or part of the gas. For example, when the driving assembly drives part of the guide vanes 211 to rotate relative to the box 1, the driving assembly can drive any guide vane 211 to rotate, can drive at least two adjacent guide vanes 211 to rotate in the same direction or opposite directions, and can also drive at least two non-adjacent guide vanes 211 to rotate in the same direction or opposite directions, so as to meet different use requirements, and is beneficial to improve the flexibility and functional diversity of the guide assembly 2.

[0074] Specifically, the detection device 3 can be arranged on at least one side of the flow guide assembly 2 along the third direction z, so that the detection device 3 can detect the temperature of the air inlet side of the flow guide assembly 2, so that the control system can directly control the driving assembly to start or stop according to the detection result of the detection device 3, and / or control the heating film to open or close, so as to realize the adjustment of the gas flow direction and the gas temperature, or so that the detection device 3 can detect the temperature of the air outlet side of the flow guide assembly 2, so that the control system can re-adjust the working state of the driving assembly and / or the heating film according to the measurement result of the detection device 3, so as to realize the verification of the gas flow direction and the gas temperature.

[0075] In a possible implementation, when the gaps between the adjacent two flow guide vanes 211 and the gaps between the edge flow guide vanes 211 and the inner wall of the box 1 are all equal, the flow area of each air supply channel 212 is close to equal, which is also beneficial to improve the uniformity of the gas distribution, thereby improving the uniformity of the gas flowing to the target area.

[0076] In a possible implementation, the angle at which the flow guide vane 211 rotates relative to the box 1 is β, and β satisfies 0°≤β≤180°, and specifically 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°, and the like.

[0077] In a possible implementation, when the heating device is in the initial state, the angle between each flow guide vane 211 of the flow guide assembly 2 and the horizontal plane is 0°, that is, the flow guide vane 211 is parallel to the horizontal plane. When the heating device is in the initial state, there is a gap between the adjacent flow guide vanes 211 along the first direction x or the second direction y, and the gap between the adjacent flow guide vanes 211 is greater than or equal to the width dimension of any flow guide vane 211 along the third direction z, so as to avoid the risk of interference when the adjacent two flow guide vanes 211 relatively rotate, and to improve the safety and reliability of the heating device during operation.

[0078] In a possible implementation, when the control system controls the driving assembly to drive a part of the flow guide vanes 211 to rotate relative to the box 1, the control system can control the heating film of the part of the rotated flow guide vanes 211 to start, or can control the heating film of another part of the unrotated flow guide vanes 211 to start, so as to enable the operator to adjust according to the demand in the actual use process, and to further improve the flexibility of the heating device.

[0079] In a possible implementation, as shown in Figure 2 , Figure 3 and Figure 4 the projection of the guide vane 211 along the third direction z is linear or arc-shaped. Through such a design, the cross-sectional shape of each air supply channel 212 is also rectangular or arc-shaped, so as to meet different requirements of the heating device in the target area during processing of special components or maintenance of special instruments, and to improve the functional diversity of the guide assembly 2.

[0080] In a specific implementation, as shown in Figure 3 the guide vane 211 extends along the first direction x and is spaced along the second direction y, and the guide assembly 2 further comprises a connecting plate 213 distributed on both sides of the guide vane 211 along the first direction x, used for connecting at least two adjacent guide vanes 211 to form a guide vane group 21, and the driving assembly is connected with the guide vane 211 through the connecting plate 213.

[0081] In the embodiment, along the arrangement direction of the guide vane 211, when at least two adjacent guide vanes 211 are connected to form the guide vane group 21 through the connecting plate 213, the stability and reliability of the connection between the adjacent guide vanes 211 can be improved, so as to improve the structural stability of the guide vane group 21, and further ensure that the air supply channel 212 inside the guide vane group 21 also has good structural stability, which is conducive to reducing the possibility of deformation of the internal air supply channel 212 due to gas impact or temperature stress, and improving the stability of the gas in the flow process.

[0082] The driving assembly can simultaneously control at least two guide vanes 211 to rotate synchronously through the connecting plate 213, which is conducive to improving the consistency of at least two adjacent guide vanes 211 during rotation, and when the gas flows in the internal air supply channel 212, a gas curtain with unified flow direction can be formed to avoid the risk of dispersed gas flow due to the angle deviation of a single guide vane 211, so as to improve the accuracy of directional gas flow, so as to further improve the accuracy of local regulation of the heating device to the guide assembly 2.

[0083] At the same time, since the driving assembly can drive at least two adjacent guide vanes 211 through the connecting plate 213, it is not necessary to provide a corresponding driving member for each guide vane 211, which is conducive to simplifying the driving mode, reducing the design difficulty of the control system, and further reducing the number of components of the driving assembly, reducing the production cost of the heating device, improving the space utilization rate inside the box 1, and making the layout structure inside the heating device more compact, so as to achieve the purpose of miniaturization of the heating device.

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

[0085] In a specific embodiment, as shown in Figure 3 The guide vanes 211 include first vanes 211a and second vanes 211b, the first vanes 211a and the second vanes 211b are alternately arranged along the second direction y, the width of the first vanes 211a is L1, the width of the second vanes 211b is L2, and L1 and L2 satisfy 0.25≤L1 / L2≤1.

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

[0087] Specifically, when the gas flows through the air supply channel 212 inside the group of guide vanes 21, due to the size difference between the first vanes 211a and the second vanes 211b, the gas can form a gas curtain with a unified flow direction and biased to the side of the first vanes 211a in the internal air supply channel 212, so as to improve the accuracy of the directional flow of the gas towards the side close to the first vanes 211a, thereby facilitating the optimization of the stability of the gas during the flow process, so as to achieve better conveying effect.

[0088] More specifically, the width ratio L1 / L2 of the first vanes 211a and the second vanes 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 vanes 211a and the second vanes 211b is too small (for example, L1 / L2 is less than 0.25), the first vanes 211a and the second vanes 211b have too large a size difference, which causes the gas to be unable to be effectively concentrated during the flow process, and there is a possibility of dispersion, so that the final coverage range of the gas is greater than the target area, not only making the accuracy control of the gas flow by the group of guide vanes 21 poor, but also easily causing waste of part of the gas.

[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 the gas can be accurately guided to the target area when flowing through the air supply channel 212 inside the guide vane group 21, and the flow direction of the gas is more easily deviated to the side of the first blade 211a with shorter size, thereby being able to guarantee the gas guide effect while optimizing the stability of the gas in the inclined transmission process, so as to achieve better conveying effect, and further guarantee the processing effect of the gas on the special components in the target area or the maintenance effect on the special equipment.

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

[0092] In a specific embodiment, as shown in Figure 2 , Figure 3 and Figure 4 , the guide vane 211 or the connecting plate 213 is provided with a rotating shaft 214, and the driving assembly includes a driving motor (not shown in the figure) and a transmission gear set (not shown in the figure). The driving motor is in transmission connection with the rotating shaft 214 through the transmission gear set, so as to rotate at least one guide vane 211 relative to the box body 1.

[0093] In the embodiment of the application, the driving motor can be connected with the rotating shaft 214 through the transmission gear set, so as to drive the guide vane 211 or the connecting plate 213 to rotate relative to the box body 1, so as to realize the adjustment of the whole or part of the guide assembly 2. The gear transmission has the characteristics of simple structure and easy realization, which is beneficial to improve the stability and reliability of the guide vane 211 or the connecting plate 213 in the rotating process. At the same time, the control precision of the guide vane 211 or the connecting plate 213 can be improved, so that the guide vane 211 or the connecting plate 213 can be rotated to a preset angle, so as to meet the requirement of the guide assembly 2 for transmission of the gas at any angle, which is beneficial to improve the flexibility and functional diversity of the guide assembly 2.

[0094] In a specific embodiment, as shown in Figure 5 , the guide assembly 2 includes a first guide group 22 and a second guide group 23. The first guide group 22 and the second guide group 23 are spaced apart along the third direction z. The projection of any guide vane 211 in the first guide group 22 and the projection of any guide vane 211 in the second guide group 23 have a first included angle a, and the first included angle a satisfies 0°<a≤90°.

[0095] In the embodiments of the present application, the first flow guide group 22 and the second flow guide group 23 each include a plurality of flow guide vanes 211 distributed at intervals, the flow guide vanes 211 in the first flow guide group 22 can extend along the second direction y and are distributed at intervals along the first direction x, and the flow guide vanes 211 in the second flow guide group 23 can extend along the first direction x and are distributed at intervals along the second direction y. Through such a design, the projection of any flow guide vane 211 in the first flow guide group 22 and the projection of any flow guide vane 211 in the second flow guide group 23 intersect with each other, so that a first included angle a can be formed, and thus the flow guide assembly 2 can transmit gas to one side or both sides along the first direction x, and can also transmit gas to one side or both sides along the second direction y, and when the flow guide vanes 211 of the first flow guide group 22 (or the second flow guide group 23) are inclined relative to the vertical plane, the flow guide vanes 211 of the second flow guide group 23 (or the first flow guide group 22) need to be rotated to a position parallel to the vertical plane, so that the air supply channels 212 of the first flow guide group 22 and the second flow guide group 23 are communicated with each other, thereby facilitating the outflow of gas from the flow guide assembly 2, and being conducive to improving the stability and smoothness of the gas in the flow process, and being conducive to further improving the flexibility and functional diversity of the flow guide assembly 2, so as to meet the needs of the flow guide assembly 2 for transmitting gas at any angle.

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

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

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

[0099] In a 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 the embodiment of the present application, the area ratio S2 / S1 of the guide vane 211 and the heating film can 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 and the heating film is too small (for example, S2 / S1 is less than 0.1), the coverage area of the heating film is too small, so that the heating film cannot fully heat the gas during the flow of the 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 and 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 flow of the gas and ensure the uniformity of the heated gas, so as to avoid the risk of local high or low temperature of the gas after flowing out of the air supply channel 212, so as to ensure the reliability of the processing of special components or the maintenance of special instruments in the target area. At the same time, since the coverage area of the heating film matches the contact area of the gas, the invalid heat dissipation can be reduced, which is beneficial to improve the energy utilization rate and reduce the operating cost of the heating device.

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

[0104] In the embodiment of the present application, since the electric heating layer of the heating film is electrically connected with the heating power supply, and the heating power supply is electrically connected or signal connected with the control system, the opening or closing of the heating power supply can directly affect the working state of the heating film, so that 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 according to the detection result of the detection device 3.

[0105] Through the design, the heating film can heat the gas in the air supply channel 212 by electric heating, so as to realize rapid heating of the heating film, improve the heating efficiency of the heating film and the heating efficiency of the gas. At the same time, the power of the heating power supply is controlled by the control system, which is conducive to further improving 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 process of machining special parts or maintaining special instruments in the target area. In addition, it can also speed up the response efficiency of the electric heating layer and shorten the temperature adjustment lag time, which is conducive to further improving the dynamic response capability and control accuracy of the control system.

[0106] The insulation layer is arranged on both sides of the electric heating layer, which can completely wrap the electric heating layer, thereby reducing the possibility of electric leakage or short circuit of the heating film during work, thereby improving the safety and reliability of the heating device during work, and further improving the working stability of the heating device, thereby prolonging the service life.

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

[0108] In the embodiment of the application, when the material of the electric heating layer is graphene composite material, the electric heating layer has good electro-thermal conversion efficiency due to the low resistivity and high thermal conductivity, thereby realizing rapid heating of the heating film 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 10 μm, 15 μm, 20 μm, 25 μm, 30 μm, 35 μm, 40 μm, 45 μm, 50 μm, 55 μm, 60 μm, 65 μm, 70 μm, 75 μm, 80 μm, 85 μm, 90 μm, 95 μm, 100 μm, etc.

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

[0111] In the embodiment of the application, when the material of the electric heating layer is nickel-chromium alloy or iron-chromium-aluminum alloy, the electric heating layer can maintain high stability at high temperature, which is conducive to improving the safety and stability of the heating film during work. In addition, the surface of the electric heating layer also has an oxide film, which has good oxidation resistance to prolong 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 uniformizing plate 4 is provided with a plurality of first through holes 41 distributed along the first direction x and the second direction y, so that the first flow uniformizing plate 4 can divide the gas flow through the arrayed first through holes 41, to reduce the possibility of uneven gas flow rate and / or flow distribution after the gas flows into the heating device, to improve the uniformity of the gas before flowing into the flow guide assembly 2, to ensure the consistency of the conditions when the gas flows into each air supply channel 212, so as to accurately adjust (for example, control part of the flow guide vanes 211 to rotate, and / or control part of the heating films to start) the flow guide assembly 2, which is conducive to further improving the control accuracy of the control system on the flow guide vanes 211 and / or the heating films.

[0119] Meanwhile, after the first flow uniformizing plate 4 uniformly divides the gas flow, it can also reduce the error of the detection device 3 in measuring the gas temperature, to improve the accuracy of the detection result, so as to avoid 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 invalid energy consumption, and reducing the operating cost of the heating device.

[0120] In addition, after the first flow uniformizing plate 4 uniformly divides the gas flow, it can also improve the stability of the gas flow, to reduce the possibility of noise or fluctuation of the flow guide assembly 2 due to the impact of the gas, thereby facilitating to improve the safety and reliability of the flow guide assembly 2 during operation.

[0121] Therefore, when the first flow uniformizing plate 4 is arranged on the air inlet side of the flow guide assembly 2 along the third direction z, the first through holes 41 can improve the flow state of the gas in the cabinet 1, and also ensure the stability and reliability of the subsequent detection device 3 and the control system during operation, thereby facilitating to improve the cooperative working capability between the local flow guide assembly and the local heating film, and further improving the overall working performance of the heating device.

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

[0123] In a specific implementation, as shown in Figure 6 The heating device further comprises a second flow uniformizing plate 5, which is installed in the cabinet 1 and located on the air outlet side of the flow guide assembly 2. The second flow uniformizing plate 5 is provided with a plurality of second through holes 51, which are distributed along the first direction x and the second direction y, and each of the second through holes 51 is in communication with the outlet end of the air supply channel 212.

[0124] In the embodiment of the present application, the second flow uniformizing plate 5 is arranged on the air outlet side of the flow guide assembly 2, so that the gas flows into each air supply channel 212 first during the flow process, and is then guided by the flow guide vanes 211 and / or heated by the heating film, and then is divided by the second flow uniformizing plate 5 to be transmitted to the target area, thereby realizing directional flow and local heating of the gas.

[0125] The second flow uniformizing plate 5 is provided with a plurality of second through holes 51 distributed along the first direction x and the second direction y, so that the second flow uniformizing plate 5 can divide the gas again through the arrayed second through holes 51, for reducing the possibility of high and low temperature stratification caused by uneven temperature distribution after the gas is heated, and for forcibly mixing gas flows of different temperatures and / or different flow rates, so as to improve the uniformity of the gas flowing out of the heating device, so as to meet the requirements of the air conditioner for processing or maintaining special components or special instruments in the target area.

[0126] At the same time, after the second flow uniformizing plate 5 uniformly divides the gas, it can directly reflect the temperature of the gas flowing 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 vanes 211 and / or the heating film, which is beneficial to improve the dynamic response capability and control precision of the control system.

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

[0128] Therefore, when the second flow uniformizing plate 5 is arranged on the air outlet side of the flow guide assembly 2 along the third direction z, the second through holes 51 can improve the flow state of the gas flowing out of the flow guide assembly 2, and can also feedback the processing effect of the flow guide assembly 2 on the gas, so that the control system can re-adjust the working state of the flow guide vanes 211 and / or the heating film, thereby being beneficial to improve the cooperative working capability between the local flow guide assembly and the local heating film, and further being beneficial to improve the overall working performance of the heating device.

[0129] In a possible implementation, the heating device can not only be provided with the first flow uniformizing plate 4 or the second flow uniformizing plate 5, but also can be provided with both the first flow uniformizing plate 4 and the second flow uniformizing plate 5.

[0130] In the embodiments of the present application, when the heating device is provided with the first flow uniformizing plate 4 and the second flow uniformizing plate 5 simultaneously, the first flow uniformizing plate 4 and the second flow uniformizing plate 5 are respectively located at the air inlet side and the air outlet side of the flow guide assembly 2 along the third direction z, and are respectively used for uniformly distributing the gas flowing into and out of the heating device, so as to form a symmetrically distributed gas flow shaping architecture, guarantee the flow uniformity and temperature uniformity when the gas flows in and out, and realize the high-precision control capability of the air conditioner.

[0131] In a possible implementation, when the angle of the flow guide vane 211 is fixed along the third direction z, the angle of the air supply channel 212 is fixed, and 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 in the flowing process.

[0132] In a specific implementation, as shown in Figure 6 The detection device 3 includes a plurality of detection pieces. When the heating device includes the first flow uniformizing plate 4, the plurality of detection pieces are arranged on the first flow uniformizing plate 4 along the first direction x and the second direction y at intervals, and the detection pieces are arranged adjacent to the first through holes 41, and are used for detecting the temperature of the gas in the first through holes 41. When the heating device includes only the second flow uniformizing plate 5 or includes the first flow uniformizing plate 4 and the second flow uniformizing plate 5 simultaneously, the plurality of detection pieces are arranged on the second flow uniformizing plate 5 along the first direction x and the second direction y at intervals, and the detection pieces are arranged adjacent to the second through holes 51, and are used for detecting the temperature of the gas in the second through holes 51.

[0133] In the embodiments of the present application, the detection device 3 can include a plurality of first detection pieces 31 or a plurality of second detection pieces 32.

[0134] Specifically, when the heating device includes the first flow uniformizing plate 4, the plurality of first detection pieces 31 are arranged on the first flow uniformizing plate 4 along the first direction x and the second direction y at intervals, and each first detection piece 31 is arranged adjacent to each first through hole 41, and is used for detecting the temperature of the gas in the adjacent first through hole 41, so as to improve the detection accuracy of the first detection piece 31, so that the control system can control the driving assembly to drive the partial flow guide vane 211 to rotate and / or control the partial heating film to heat according to the detection result of the first detection piece 31, thereby realizing the processing of special components or the maintenance of special instruments in the target region by the heating device.

[0135] When the first detection piece 31 is arranged at the air inlet side of the flow guide assembly 2, the first detection piece 31 can directly detect the temperature of the gas, which is beneficial to reduce the error of the detection device 3 in measuring the temperature of the gas, so as to improve the accuracy of the detection result, thereby avoiding the control system from controlling too many or too few heating films to continue adjusting the temperature of the gas, and further improving the effective utilization rate of energy, reducing invalid energy consumption, and reducing the operating cost of the heating device.

[0136] Meanwhile, the projections of each first detection member 31 and each first through hole 41 along the first direction x and the second direction y can be distributed in a staggered manner, so that the first detection member 31 is diagonally distributed relative to the first through hole 41, so that the first detection member 31 can detect the gas temperature in at least four first through holes 41 around it. Through such a design, the first detection member 31 can detect the gas temperature in a local range of the first flow uniforming plate 4, so as to reduce the number of first detection members 31 used and reduce the production cost, so as to be able to reduce the reference number of detection results, and further to be able to reduce the difficulty of subsequent sorting, calculation and judgment of the control system, and to be beneficial to improve the response efficiency of the control system.

[0137] In other embodiments, the first detection member 31 can also be arranged in the first through hole 41, so as to further improve the accuracy of the detection result.

[0138] Specifically, when the heating device only includes the second flow uniforming plate 5 or simultaneously includes the first flow uniforming plate 4 and the second flow uniforming plate 5, a plurality of second detection members 32 are distributed on the second flow uniforming plate 5 along the first direction x and the second direction y, and each second detection member 32 is arranged adjacent to each second through hole 51, for detecting the gas temperature in the adjacent second through hole 51, so as to improve the detection accuracy of the second detection member 32, so that the control system can control the driving assembly to drive the partial flow guide vane 211 to rotate and / or control the partial heating film to heat, so as to realize the processing of special components or the maintenance of special instruments in the target area by the heating device.

[0139] When the second detection member 32 is arranged on the air outlet side of the flow guide assembly 2, the first detection member 31 does not need to be arranged on the air inlet side of the flow guide assembly 2, and the second detection member 32 can directly reflect the temperature of the gas after flowing 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 vane 211 and / or the heating film, which is beneficial to improve the dynamic response ability and control precision of the control system, and reduce the production cost of the heating device.

[0140] Meanwhile, the projections of each second detection member 32 and each second through hole 51 along the first direction x and the second direction y can be distributed in a staggered manner, so that the second detection member 32 is diagonally distributed relative to the second through hole 51, so that the second detection member 32 can detect the gas temperature in at least four second through holes 51 around it. Through such a design, the second detection member 32 can detect the gas temperature in a local range of the second flow uniforming plate 5, so as to reduce the number of second detection members 32 used and reduce the production cost, so as to be able to reduce the reference number of detection results, and further to be able to reduce the difficulty of subsequent sorting, calculation and judgment of the control system, and to be beneficial to improve the response efficiency of the control system.

[0141] In other embodiments, the second detection member 32 can also be arranged in the second through hole 51 to further improve the accuracy of the detection result.

[0142] Therefore, by arranging the detection device 3 on the first flow uniforming plate 4 or the second flow uniforming plate 5, the closed-loop control mode of the detection, adjustment and heating of the gas temperature by the heating device can be realized, and the response time can be shortened, the work efficiency can be improved, the real-time dynamic adjustment of the gas temperature can be realized efficiently and accurately, the flexibility of the heating device in the working process can be improved, and the actual use requirements can be met.

[0143] The embodiments of the present application also provide a control method of a heating device, the heating device being any one of the heating devices described above, and being used for transmitting a gas to a target area to realize the processing of special components or the maintenance of special instruments by an air conditioner, the preset temperature of the target area being T0, and the control method comprising the following steps of:

[0144] detecting the first gas temperature T1 at the air inlet side of the flow guide assembly 2 or the second gas temperature T2 at the air outlet side of the flow guide assembly 2; when T0 and T1 satisfy T0>T1 or T0 and T2 satisfy T0>T2, controlling the driving assembly to drive the at least one flow guide vane 211 to rotate to align the air supply channel 212 with the target area, and controlling the heating film to be in an 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, controlling the driving assembly to drive the at least one flow guide vane 211 to rotate to align the air supply channel 212 with the target area, and controlling the heating film to be in a closed state.

[0145] In the embodiments of the present application, when the heating device comprises the first flow uniforming plate 4, the first flow uniforming plate 4 is provided with the first detection member 31 for detecting the gas temperature in the adjacent first through hole 41, so that the control system can control the driving assembly to drive part of the flow guide vanes 211 to rotate and / or control part of the heating films to heat according to the detection result of the first detection member 31, or when the heating device only comprises the second flow uniforming plate 5 or simultaneously comprises the first flow uniforming plate 4 and the second flow uniforming plate 5, the second flow uniforming plate 5 is provided with the second detection member 32 for detecting the gas temperature in the adjacent second through hole 51, so that the control system can control the driving assembly to drive part of the flow guide vanes 211 to rotate and / or control part of the heating films to heat according to the detection result of the second detection member 32, thereby realizing the processing of special components or the maintenance of special instruments in the target area by the heating device.

[0146] Specifically, since the first detection member 31 is arranged at the air inlet side of the flow guide assembly 2, the first detection member 31 can directly detect the temperature of the gas, which is conducive to reducing the error of the detection device 3 in measuring the temperature of the gas, improving the accuracy of the detection result, and avoiding the control system from continuously adjusting the heating film to control the temperature of the gas too much or too little, thereby improving the effective utilization rate of energy, reducing invalid energy consumption, and reducing the operating cost of the heating device.

[0147] Specifically, since the second detection member 32 is arranged at the air outlet side of the flow guide assembly 2, the second detection member 32 can directly reflect the temperature of the gas flowing out of the flow guide assembly 2, and can provide real and effective feedback for the control system, so that the control system adjusts the working state of the flow guide vane 211 and / or the heating film, which is conducive to improving the dynamic response capability and control precision 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 less than the preset temperature of the target area. At this time, the control system can control the driving assembly to drive at least one flow guide vane 211 to rotate according to the preset program, so that the air supply channel 212 is aligned with the target area, and the heating film is in an 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 driving assembly to drive at least one flow guide vane 211 to rotate according to the preset program, so that the air supply channel 212 is aligned with the target area, and the heating film is in an open state to heat the gas in the air supply channel 212 to T0 and T2 satisfy T0≤T2, at this time, the control system can control the driving assembly to drive the part of the flow guide vane 211 to stop rotating according to the preset program, so as to realize the fixation of the air supply channel 212, improve the accuracy of the gas flowing to the target area, and at the same time, the control system can control the heating power of the heating film to remain unchanged 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, and further ensuring the stability and reliability of the air conditioner during operation.
