[0047] In related technologies, air conditioning equipment can regulate air temperature. The air conditioning equipment is equipped with an induction coil to generate an alternating magnetic field. The alternating magnetic field is generated on both sides of the coil. In some existing technologies, a metal plate is placed on the side close to the coil to induce eddy currents. This design makes it difficult to reduce the leakage of the magnetic field on the other side, affecting the magnetic field strength.

[0048] The following is for reference. Figures 2-7 Air handling equipment 1 according to an embodiment of the present utility model is described.

[0049] like Figure 2As shown, the air handling device 1 according to this utility model includes: a heating element 10, a fan 20, a coil module 30, and a shielding module 40. The heating element 10 is formed as a hollow cylinder; at least a portion of the fan 20 is located inside the heating element 10; the coil module 30 includes an electromagnetic coil capable of generating a magnetic field, the electromagnetic coil being located outside the heating element 10 so that the heating element 10 heats up under the action of the magnetic field; the shielding module 40 is disposed outside the coil module 30 and is configured to shield the magnetic field. Specifically, the coil module 30 and the heating element 10 constitute the temperature regulation structure of the air handling device 1. The heating element 10 can heat up under the action of the magnetic field of the electromagnetic coil, so that the air handling device 1 has a temperature regulation function. Through the cooperation of the electromagnetic coil and the heating element 10, electromagnetic induction heating can be realized. The heating element 10 is disposed inside the air handling device 1, so that the heating element 10 can heat the airflow entering the air handling device 1, so that the air handling device 1 can output hot air. The fan 20 is provided at the temperature regulation structure, which can guide the airflow direction inside the air handling device 1 and also facilitate heat dissipation of the temperature regulation structure.

[0050] Here, the shielding module 40 is located on the side of the electromagnetic coil away from the heating element 10. After the electromagnetic coil is energized, a magnetic field will also be generated on the side of the electromagnetic coil away from the heating element in the radial direction of the impeller 20, causing magnetic field leakage. By setting the shielding module 40 on the side of the electromagnetic coil away from the heating element, the amount of magnetic field leakage on the side of the electromagnetic coil away from the heating element can be reduced, and the magnetic field strength on the side of the electromagnetic coil close to the heating element can be increased to improve the heating effect of the heating element, thereby improving the heating efficiency of the air handling equipment 1.

[0051] According to the present invention, the air handling device 1 has a heating element 10 disposed inside the coil module 30 and a shielding module 40 disposed outside the coil module 30, so as to reduce the leakage of the magnetic field outside the coil module 30 and increase the magnetic field strength of the electromagnetic coil near the heating element, thereby improving the heating effect of the heating element and thus improving the heating efficiency of the air handling device 1.

[0052] According to some embodiments of this utility model, the shielding module 40 includes a mounting bracket 41 and a shielding layer, with the shielding layer covering at least a portion of the mounting bracket 41. Here, the shielding layer is disposed on the outside of the coil module 30 via the mounting bracket 41, which provides a mounting position for the shielding layer. The shielding layer serves to reduce the leakage of the magnetic field on the side of the electromagnetic coil away from the heating element. In some embodiments, the shielding layer may refer to a shielding material coated on at least a portion of the surface of the mounting bracket 41, or it may refer to other structural components with magnetic field shielding effects, depending on the actual situation.

[0053] In some embodiments, the mounting bracket 41 may refer to the housing 50 of the entire air handling unit 1, or it may be a separate structural component.

[0054] According to some embodiments of this utility model, the shielding layer includes multiple shielding elements, which are spaced apart circumferentially along the mounting bracket 41. Each shielding element is a magnetically conductive material. Here, the shielding module 40 includes a mounting bracket 41 and shielding elements. The mounting bracket 41 is sleeved on the outside of the electromagnetic coil, and the shielding elements are disposed on the outer peripheral wall of the mounting bracket 41 facing away from the airflow channel. In some embodiments, the mounting bracket 41 is formed in a ring shape, and in the radial direction of the impeller 20, the mounting bracket 41 is sleeved on the radial outside of the electromagnetic coil. The mounting bracket 41 is used to mount the shielding elements. By setting the mounting bracket 41, the assembly of the shielding elements is facilitated, and the assembly reliability of the shielding elements is improved.

[0055] Furthermore, the shielding component is made of a magnetically conductive material. In some embodiments, the shielding component includes a plurality of permanent magnets spaced apart circumferentially along the electromagnetic coil. By spaced apart multiple permanent magnets circumferentially along the electromagnetic coil, the shielding module 40 improves the effectiveness of shielding the electromagnetic coil from magnetic field leakage on the side away from the heating element. Moreover, the permanent magnets have high stability and can maintain their magnetism for a long time, which helps extend the service life of the shielding module 40.

[0056] In some embodiments, the material of the shielding component may be a ferrite magnetic material.

[0057] According to some embodiments of this utility model, such as Figure 6 As shown, the angle between the ends of two adjacent shielding components facing each other and the center of the circle is no greater than 60 degrees. Specifically, the shielding components are generally designed according to the shape of the electromagnetic coil. In some examples, multiple shielding components are arranged circumferentially along the mounting bracket 41. The angle between the ends of adjacent shielding components facing each other and the center of the circle is An. To ensure the shielding effect of the shielding components in preventing magnetic field leakage, the value of An should not be too large. Here, the value of An is no greater than 60°. For example, An can be 30°, 45°, 50°, etc.

[0058] According to some embodiments of this utility model, such as Figure 3 As shown, the shielding component is located on the side of the mounting bracket 41 away from the coil module 30 to improve the shielding effect of the shielding module 40 on the side of the electromagnetic coil away from the heating element, thereby reducing the amount of magnetic field leakage outside the coil module 30. And, Figure 3 The structural orientation shown does not represent the actual orientation of the product.

[0059] According to some embodiments of this utility model, such as Figure 6As shown, the height of the shielding component in the radial direction of the impeller 20 is Hc, with a value ranging from 3mm to 10mm; and / or the width of the shielding component in the circumferential direction of the mounting bracket 41 is Wc, with a value ranging from 10mm to 30mm. Here, the height of the shielding component in the radial direction of the impeller 20 is Hc, and the width of the shielding component in the circumferential direction of the mounting bracket 41 is Wc. To ensure the shielding effect of the shielding component on the magnetic field of the electromagnetic coil away from the heating element, and to keep the shielding component in a small volume, it is sufficient to satisfy at least one of Wc being in the range of 10mm to 30mm and Hc being in the range of 3mm to 10mm. For example, Wc can be 10mm, 12mm, 25mm, etc., and Hc can be 3mm, 5mm, 7mm, etc.

[0060] According to some embodiments of this utility model, such as Figure 7 As shown, the length of the shielding component is greater than the length of the electromagnetic coil in the axial direction of the impeller 20. In some embodiments, the length of the shielding component in the axial direction of the impeller 20 is Lc, and Lc is not less than the length of the electromagnetic coil in the axial direction, so as to ensure the shielding effect of the shielding component on the magnetic field of the electromagnetic coil on the side away from the heating element.

[0061] According to some embodiments of this utility model, such as Figure 5 As shown, the mounting bracket 41 includes multiple mounting portions 411 and connecting portions 412. The mounting portions 411 are used to fix multiple shielding components. Circumferentially adjacent mounting portions 411 are connected by connecting portions 412. In the axial direction of the impeller 20, the length of the mounting portion 411 is greater than the length of the connecting portion 412. Specifically, the mounting portions 411 on the mounting bracket 41 are used to mount shielding components, and the connecting portions 412 on the mounting bracket 41 are used to connect adjacent mounting portions 411. The length of the connecting portion 412 in the axial direction of the impeller 20 is less than the length of the mounting portion 411 in the axial direction of the impeller 20, so as to make the mounting bracket 41 lightweight, reduce the weight and cost of the mounting bracket 41, and facilitate the arrangement of other structures of the air handling equipment 1.

[0062] According to some embodiments of this utility model, such as Figure 5 As shown, each mounting part 411 is provided with a receiving groove 411a for accommodating the corresponding shielding component. The shielding component is installed in the receiving groove 411a to prevent the shielding component from detaching from the mounting bracket 41 when the air handling equipment 1 is working, and to ensure the connection stability between the shielding component and the mounting bracket 41.

[0063] According to some embodiments of this utility model, such as Figure 5As shown, each mounting part 411 is provided with a positioning part 4111 for positioning the shielding component in the receiving groove 411a, so as to realize the positioning and installation of the shielding component on the mounting bracket 41, further ensuring the connection stability between the shielding component and the mounting bracket 41, thereby ensuring the working stability of the air handling equipment 1.

[0064] According to some embodiments of this utility model, such as Figure 5 As shown, the positioning part 4111 is formed as an elastic snap, which abuts against the end face of the shielding member to facilitate the installation of the shielding member on the mounting bracket 41 and to facilitate subsequent disassembly and maintenance of the shielding member, thus simplifying the disassembly and assembly operations. In some embodiments, the elastic snap is configured as a plurality of snaps arranged on the outer periphery of the receiving groove 411a.

[0065] According to some embodiments of this utility model, such as Figure 5 As shown, the minimum distance between the coil module 30 and the shielding component in the radial direction of the impeller 20 is Sc, where Sc ≤ 4mm. In some embodiments, the distance between the shielding component and the electromagnetic coil in the radial direction of the impeller 20 is Sc. To ensure the shielding effect of the shielding component on the magnetic field of the electromagnetic coil on the side away from the heating element, the value of Sc should not be greater than 4mm. For example, Sc can be 1mm, 2mm, 3.5mm, 4mm, etc.

[0066] According to some embodiments of this utility model, the impeller 20 is a centrifugal impeller 20, and the heating element 10 is located on the radial outer side of the centrifugal impeller 20. The inner peripheral wall of the heating element 10 is used to guide the radially outgoing airflow of the centrifugal impeller 20 toward the air outlet 52 of the air handling device 1. Specifically, the air inlet and outlet directions of the centrifugal impeller 20 are mainly axial air inlet and radial air outlet. By setting the heating element 10 on the radial outer side of the impeller 20, the heating element 10 is arranged on the air outlet side of the impeller 20, which facilitates the air flowing out of the impeller 20 to flow through the heating element 10, and the heating element 10 can guide the air to flow toward the air outlet 52, so that the air handling device 1 can output hot air.

[0067] According to some embodiments of this utility model, such as Figure 3 As shown, the centrifugal impeller 20 has blades formed on it. Each blade has a first portion 21 and a second portion 22 arranged sequentially in the axial direction. The first portion 21 is located inside the heating element 10, and the second portion 22 is located outside the heating element 10. Specifically, the first portion 21 of the blade is located inside the heating element 10 and is suitable for dissipating heat from the heating element 10, while the second portion 22 of the blade is located outside the heating element 10 and is suitable for dissipating heat from the outer coil module 30. The difference in outer diameter between the first portion 21 and the second portion 22 is designed to optimize the heat dissipation effect of the impeller 20 on the heating element 10 and the coil module 30.

[0068] It should be noted that the first part 21 and the second part 22 of the blade can be directly connected or arranged at intervals. For example, in some embodiments, the first part 21 and the second part 22 of the blade are connected sequentially along the axial direction of the centrifugal impeller 20; in other embodiments, the first part 21 and the second part 22 of the blade are arranged at intervals along the circumferential direction of the centrifugal impeller 20. In this embodiment, the first part 21 and the second part 22 of the blade are not directly connected. In other embodiments, other situations are also possible, as long as the first part 21 of the blade can be located inside the heating element 10 and guide the airflow to the inner wall of the heating element 10, and the second part 22 can be located outside the heating element 10 and guide the airflow to the outer side of the heating element 10.

[0069] According to some embodiments of this utility model, the diameter of the second part 22 is larger than the diameter of the first part 21, and the second part 22 is at least directly opposite the coil module 30 in the axial direction of the impeller 20. Here, the diameter of the blades of the second part 22 is larger than the diameter of the blades of the first part 21 to increase the heat dissipation area of ​​the blades of the second part 22 on the coil module 30 and improve the heat dissipation effect of the blades of the second part 22 on the coil module 30. At least a portion of the structure of the blades of the second part 22 may be radially opposite to the coil module 30 to guide airflow to the coil module 30; alternatively, at least a portion of the structure of the blades of the second part 22 may be axially opposite to the coil module 30 to discharge air to the coil module 30. Furthermore, the entire blades of the second part 22 may be directly opposite the coil module 30, or only a portion of the structure of the blades of the second part 22 may be directly opposite the coil module 30, and the design can be customized according to actual needs.

[0070] In some embodiments, the air handling device 1 further includes a drive member 60, which is connected to the impeller 20 and adapted to drive the impeller 20 to rotate, so that the impeller 20 can drive airflow.

[0071] In some embodiments, the air handling unit 1 further includes a housing 50, which has an air inlet 51 and an air outlet 52. The housing 50 contains a duct space connecting the air inlet 51 and the air outlet 52. External air can enter the duct space through the air inlet 51 and then exit through the air outlet 52. The heating element 10, impeller 20, coil module 30, and shielding module 40 of the air handling unit 1 are disposed within the duct space to electromagnetically induction heat the airflow passing through the duct space, enabling the air handling unit 1 to output hot air.

[0072] Here, the housing 50 can position and support the drive unit 60, the impeller 20 and the heating element 10, ensuring the overall stability of the air handling equipment 1. Furthermore, the drive unit 60, the impeller 20 and the heating element 10 are housed inside the housing 50. The protection of the housing 50 reduces the risk of these structures interfering with external structures, thereby reducing the risk of damage to the air handling equipment 1 and extending its service life.

[0073] According to some embodiments of this utility model, the shielding layer is constructed from at least one of neodymium iron boron permanent magnets, ferrite permanent magnets, silicon steel, metal soft magnetic powder cores, and ferrite soft magnets. Here, the shielding layer is generally a magnetic material. Magnetic materials can be classified according to their function into permanent magnet materials, soft magnetic materials, and functional magnetic materials. Currently, the most commonly used permanent magnet materials in new energy vehicles are neodymium iron boron permanent magnets and ferrite permanent magnets, as well as soft magnetic materials such as silicon steel, metal soft magnetic powder cores, and ferrite soft magnets. The appropriate material can be selected based on actual needs.

[0074] The following is a simplified description of the assembly method of air handling equipment 1.

[0075] Assembly Method 1: The heating element 10 is fixedly connected to the coil module, and the shielding component is fixedly installed on the mounting bracket 41. The mounting bracket 41 is sleeved on the radial outer side of the coil module and fixedly connected to the coil module. The impeller 20 can be positioned in the center area of ​​the heating element 10 by hand. The electronic control components are arranged between the impeller 20 and the heating element 10, thereby realizing the modular assembly of the heating element 10, the coil module, the electronic control components, the shielding module, and the impeller 20. Then, the above components are placed into the housing 50, and the coil module is further fixedly connected to the housing 50, so that the impeller 20 is connected to the housing 50. Finally, the housing 50 is sealed to complete the assembly of the air conditioning device 1.

[0076] In order to ensure the assembly reliability of the components inside the housing 50 with the housing 50, the mounting bracket 41 can be further connected to the housing 50 to reduce the risk of the structural components inside the housing 50 falling off the housing 50.

[0077] Assembly Method 2: First, the heating element 10 is fixedly installed inside the housing 50. Then, the coil module with the electromagnetic coil is fitted on the radial outer side of the heating element 10 and fixedly connected to the housing 50. Next, the mounting bracket 41 with the shielding is fitted on the radial outer side of the coil module and fixedly connected to the housing 50. Then, the impeller 20 is positioned in the central area of ​​the heating element 10 and connected to the housing 50. The electrical control components can be installed on the mounting bracket 41 or the housing 50. Finally, the housing 50 is sealed to complete the assembly of the air handling equipment 1.

[0078] Optionally, the above-mentioned fixed connection method can be to fix the components together by means of threaded connectors, so as to facilitate the disassembly, maintenance and cleaning of the air handling equipment 1. Of course, it is understood that the fixed connection method includes, but is not limited to, connecting by threaded connectors, or by snap-fit, etc. The specific fixed connection method can be determined according to the actual production requirements, and is not specifically limited here.

[0079] In the air handling device 1 designed according to this application, the airflow outside the air handling device 1 enters the interior of the housing 50 through the air inlet on the housing 50, and the airflow flows radially through the second part 22 and the first part 21 under the drive of the centrifugal impeller 20.

[0080] The airflow blown out by the second part 22 flows over the outside of the heating element 10. For example, this airflow can be blown directly towards the electromagnetic coil in the radial direction, or towards the gap between the heating element 10 and the electromagnetic coil, so as to dissipate heat on the electromagnetic coil and / or the surface of the heating element 10 facing the electromagnetic coil. This heat dissipation airflow can be blown out through the air outlet on the housing. The airflow blown out by the first part 21 can be blown towards the surface of the heating element 10 away from the electromagnetic coil, so as to dissipate heat on the surface of the heating element 10 away from the electromagnetic coil. This airflow can flow into the heat dissipation channel through the connecting channel opened on the heating element 10, so as to merge with the airflow blown out by the second part 22 and be blown out through the air outlet on the housing, or directly blown out through the air outlet on the housing.

[0081] The following is a brief description of the heater 1000 according to this utility model.

[0082] like Figure 1 As shown, the heater 1000 according to the present invention includes the air handling device 1 described in any of the above embodiments. Since the heater 1000 according to the present invention is equipped with the air handling device 1 of the above embodiments, the heater 1000 provides a better user experience.

[0083] In some embodiments, the heater 1000 further includes a bracket 2, and the air handling unit 1 is rotatably mounted on the bracket 2. The bracket 2 can serve as a mounting carrier for the air handling unit 1 to support it. By rotatably mounting the air handling unit 1 on the bracket 2, the air outlet direction of the heater 1000 can be adjusted, which helps to improve the heating effect and heating uniformity of the heater 1000 and enhances the user experience.

[0084] In some embodiments, the bracket 2 of the heater 1000 is rotatably connected to the base of the heater 1000. The base of the heater 1000 is provided with a drive unit for driving the bracket 2 to swing in the left-right direction. The bracket 2 of the heater 1000 forms an installation space, and the inner wall of the installation space is provided with a connecting part. The air handling unit 1 is rotatably connected to the connecting part and accommodated in the installation space. For example, the connecting part of the bracket 2 of the heater 1000 clamps the air handling unit 1 in the left-right direction and drives the air handling unit 1 to swing up and down. Optionally, the up-and-down swing of the air handling unit 1 can also be in the form of a guide rail. Alternatively, the bracket 2 of the heater 1000 can be disposed on the base of the heater 1000, and the drive unit can be disposed on the bracket 2 of the heater 1000 and together with the air handling unit 1 to drive the air handling unit 1 to swing up and down or left and right.

[0085] In some embodiments, the heater 1000 has a cold air operation mode and a warm air operation mode. The user can choose whether to operate in cold air mode or warm air mode to ensure that the heater can provide appropriate air output according to the user's needs, which helps to improve the functionality of the heater.

[0086] Based on this, the operating mode of the heater 1000 can be controlled by controlling the operating status of the fan wheel 20 and the heating element 10. When the heater 1000 is in the cold air operating mode, the fan wheel 20 can be started to generate cold air, while the heating element 10 does not work, so as to ensure that the heater 1000 can provide pure cold air, so that the heater 1000 can be used to cool down the environment with high temperature, and at the same time, it helps to reduce the energy consumption of the heater 1000.

[0087] It should be noted that when the heater 1000 is started and selected to run in cold air mode, there is no action to stop the heating element 10. However, if the heater 1000 switches from warm air mode to cold air mode, there is an action to stop the heating element 10.

[0088] When the heater 1000 is in the warm air operation mode, the fan 20 and the heating element 10 work simultaneously to ensure that the heater 1000 can output hot air, so that the heater 1000 can be used to heat low-temperature environments.

[0089] In some embodiments, the cold air operation mode of the heater 1000 needs to ensure that the output air speed of the heater 1000 is high enough. That is, the number of speed settings in the cold air operation mode of the heater 1000 is greater than the number of speed settings in the warm air operation mode, and the maximum air speed in the cold air operation mode is greater than the maximum air speed in the warm air operation mode. For example, the heater 1000 can have 8 speed settings in the cold air operation mode and 3 speed settings in the warm air operation mode. When the heater 1000 switches directly from the 3rd speed setting in the cold air mode to the warm air mode, the heater 1000 operates at the maximum speed setting (i.e., the third speed setting) in the warm air mode, and the output heat of the heater 1000 is most efficient.

[0090] In summary, the air handling equipment 1 of this utility model has a shielding module 40 disposed on the outside of the coil module 30 to reduce the leakage of the magnetic field on the outside of the coil module 30, ensure the magnetic field strength of the electromagnetic coil, and increase the magnetic field strength of the electromagnetic coil on the side close to the heating element, thereby improving the heating effect of the heating element and thus improving the heating efficiency of the air handling equipment 1.
