Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] The following is for reference. Figures 1-8 This invention describes an air handling device 100 according to an embodiment of the present invention.

[0052] Combination Figures 1 to 3 According to an embodiment of the present utility model, the air handling device 100 includes: a housing 110, a fan 120, and a first power module 130. The housing 110 is provided with an air inlet 111 and an air outlet 112. The fan 120 includes a fan wheel 121 and a motor 122. The fan wheel 121 is disposed inside the housing 110. The motor 122 is connected to the fan wheel 121 to drive the fan wheel 121 to rotate. The rotation of the fan wheel 121 drives the airflow. The first power module 130 is connected to the motor 122 to supply current to the motor 122.

[0053] For example, air can enter the housing 110 through the air inlet 111. The first power module 130 can supply current to the motor 122 and make the motor 122 run. The motor 122 can convert electrical energy into mechanical energy to drive the impeller 121 to rotate, so that the impeller 121 can drive air from the air inlet 111 to the air outlet 112, thereby improving the air flow efficiency inside the housing 110.

[0054] Combination Figures 1 to 3The air handling equipment 100 also includes an electromagnetic module 140, which is located inside the housing 110. The electromagnetic module 140 includes an electromagnetic coil for generating a magnetic field and a second power module 142. The second power module 142 is electrically connected to the electromagnetic coil to supply current to the electromagnetic coil. When the electromagnetic coil is energized, the electromagnetic coil can generate a magnetic field.

[0055] Combination Figures 1 to 3 The first power module 130 and the second power module 142 are arranged at intervals.

[0056] For example, when there is sufficient space inside the housing 110 along the axial direction of the impeller 121, the first power module 130 and the second power module 142 can be spaced apart along the axial direction of the impeller 121; when there is sufficient space inside the housing 110 along the radial direction of the impeller 121, the first power module 130 and the second power module 142 can be spaced apart along the radial direction of the impeller 121.

[0057] Considering that one of the first power module 130 and the second power module 142 is an isolated circuit and the other is a non-isolated circuit, by setting the first power module 130 and the second power module 142 alternately, it is beneficial to improve the electrical control reliability of the air handling equipment 100 and to improve the space utilization rate within the housing 110, thereby facilitating the miniaturization design of the air handling equipment 100.

[0058] In related technologies, the integrated design of IH control components and motor power supply components is not conducive to ensuring the electrical control reliability of air handling equipment, and it also tends to result in a large space required for arranging IH control components and motor power supply components, affecting the size of air handling equipment.

[0059] This application improves the electrical control reliability of the air handling equipment 100 by arranging the first power module 130 and the second power module 142 separately. At the same time, the separate arrangement of the first power module 130 and the second power module 142 can effectively improve the space utilization within the housing 110, thereby reducing the space required to arrange the first power module 130 and the second power module 142, which is conducive to realizing the miniaturization design of the air handling equipment 100.

[0060] In some embodiments of this utility model, the motor 122 is a DC motor, and the first power supply module 130 is adapted to supply DC power to the motor 122.

[0061] DC motors are smaller than AC motors, which helps to reduce the space occupied by motor 122 in housing 110, thereby saving installation space for other components in housing 110 and facilitating the miniaturization design of air handling equipment 100.

[0062] In some embodiments, the second power module 142 may be configured to supply alternating current to the electromagnetic coil.

[0063] Combination Figure 2 and Figure 3 In some embodiments of this utility model, the first power module 130 and the second power module 142 are respectively disposed on the outside of the impeller 121, so as to facilitate the separate installation of the first power module 130, the second power module 142 and the impeller 121, which helps to reduce the risk of mutual interference between the first power module 130, the second power module 142 and the impeller 121 during the installation process, and helps to improve the assembly convenience of the air handling equipment 100.

[0064] Optionally, "outer side of the impeller 121" can be the outer side of the impeller 121 in the radial direction or the outer side of the impeller 121 in the axial direction. The first power module 130 and the second power module 142 can be disposed inside or outside the housing 110. The specific arrangement of the first power module 130 and the second power module 142 can be determined according to the installation space inside the housing 110, and no specific limitation is made here. For example, in order to save installation space inside the housing 110, the first power module 130 and the second power module 142 can both be disposed outside the housing 110, as long as the first power module 130 and the second power module 142 are spaced apart.

[0065] Combination Figures 1 to 3 In some embodiments of this utility model, the second power module 142 is located on the air outlet side of the impeller 121, and the impeller 121 blows air toward the second power module 142.

[0066] In other words, the air flowing out from the impeller 121 can flow through the second power module 142 to dissipate heat from the second power module 142, which is beneficial to improving the heat dissipation efficiency and effect of the second power module 142. At the same time, it facilitates the assembly of the second power module 142 and the impeller 121, and helps to prevent the second power module 142 and the impeller 121 from interfering with each other during the installation process, thereby improving the production and assembly efficiency of the air handling equipment 100.

[0067] Combination Figures 1 to 3 In some embodiments of this utility model, the housing 110 is provided with a heat dissipation area 113, which is correspondingly provided with the second power module 142, and the airflow flowing through the second power module 142 flows outward through the heat dissipation area 113.

[0068] For example, a duct space 116 is formed inside the housing 110, which connects the air inlet 111 and the air outlet 112. The impeller 121, the first power module 130 and the second power module 142 can all be arranged in the duct space 116. The heat dissipation area 113 is connected to the duct space 116 and can be arranged directly opposite the second power module 142.

[0069] When air flows into the air duct space 116 from the air inlet 111 and enters the impeller 121, the air can be further discharged from the air outlet side of the impeller 121 and can flow through the second power module 142. The air flowing through the second power module 142 can dissipate heat from the second power module 142. After exchanging heat with the second power module 142, the air can be further discharged from the housing 110 through the heat dissipation area 113, which is beneficial to improving the heat dissipation efficiency of the second power module 142.

[0070] The heat dissipation area 113 can be formed at the bottom of the housing 110, that is, the heat dissipation area 113 is set downward to prevent debris (such as water and dust) from entering the housing 110 through the heat dissipation area 113 and affecting the operation of the internal components of the housing 110. Correspondingly, since the second power module 142 is set in the lower region of the air duct space 116, the second power module 142 can be set in the lower region of the air duct space 116.

[0071] Combination Figures 1 to 3 In some embodiments of this utility model, the heat dissipation area 113 includes a plurality of spaced through holes 1131.

[0072] The through hole 1131 is provided through the housing 110 along the thickness direction of the housing 110. It can also be understood that the through hole 1131 is provided through the housing 110 along the radial direction of the impeller 121. Multiple through holes 1131 are arranged at intervals on the housing 110 along the circumference and axial direction of the impeller 121. That is, multiple through holes 1131 are arranged in an array on the housing 110 and are all spatially connected to the impeller 121. By providing multiple through holes 1131, it is beneficial to improve the efficiency of air exhaust after heat exchange with the second power module 142, thereby further improving the heat dissipation efficiency of the second power module 142.

[0073] Combination Figures 3 to 5 In some embodiments of the present invention, the air handling device 100 further includes a radiator 150, which includes a plurality of spaced heat sinks 151 and is located on the second power module 142.

[0074] By placing the heat sink 150 on the second power module 142, the heat sink 151 can increase the heat dissipation area of ​​the second power module 142. At the same time, by arranging multiple heat sinks 151 at intervals, heat dissipation channels can be formed between two adjacent heat sinks 151, which helps to further improve the heat dissipation efficiency and heat dissipation effect of the second power module 142, reduce the risk of overheating of the second power module 142, and help ensure the normal operation of the second power module 142.

[0075] Combination Figures 3 to 5 In some embodiments of this utility model, the second power module 142 includes a first power board 1421 and a first component 1422, with the first component 1422 disposed on the side of the first power board 1421 facing the air inlet 111.

[0076] It should be noted that the first component 1422 may include power devices (IGBTs and bridge rectifiers), capacitors, inductors, resistors, and transformers, etc. In addition, the first power board 1421 is also provided with a signal socket and a power input interface. The signal socket is used to connect external devices (such as sensors, controllers, or other electronic devices) to facilitate data exchange and communication. The power input interface is used to connect to the power supply system of the first power board 1421 to provide the first power board 1421 with the power required for operation and ensure that the components on the first power board 1421 can operate normally.

[0077] The first power board 1421 serves as the mounting carrier for the first component 1422. The first component 1422 can be arranged on the first power board 1421 and electrically connected to it. When the second power module 142 is working, the first component 1422 will generate heat. By setting the first component 1422 on the side of the first power board 1421 facing the air inlet 111, the air entering the housing 110 through the air inlet 111 can preferentially flow through the first component 1422 and dissipate heat from it. This is beneficial to improving the heat dissipation efficiency of the first component 1422, further reducing the risk of overheating of the second power module 142, and improving the service life of the air handling equipment 100.

[0078] Combination Figures 1 to 3 In some embodiments of this utility model, the wind turbine 121 is provided with a clearance space 1211 for avoiding the second power module 142.

[0079] For example, at least a portion of the second power module 142 can be located within the clearance space 1211, which helps to reduce the space required to arrange the second power module 142 within the housing 110. It also enables the integration of the second power module 142 with the impeller 121, making the structure of the second power module 142 and the impeller 121 compact. This helps to reduce the volume of the air handling equipment 100, facilitates the miniaturization design of the air handling equipment 100, and further helps to reduce the space required to arrange the air handling equipment 100.

[0080] Optionally, the second power module 142 can be entirely disposed within the clearance space 1211, or the portion of the second power module 142 closest to a particular wheel can be disposed within the clearance space 1211. The specific portion of the second power module 142 located within the clearance space 1211 can be determined according to actual production requirements and is not specifically limited here.

[0081] Reference Figure 6 In some embodiments of this utility model, the portion of the second power module 142 located within the clearance space 1211 is spaced apart from the inner wall of the clearance space 1211.

[0082] Since the clearance space 1211 is located on the wind turbine 121, and the inner wall of the clearance space 1211 is part of the wind turbine 121, in order to prevent the second power module 142 from interfering with the operation of the wind turbine 121 due to contact with the inner wall of the clearance space 1211, it is necessary to set the portion of the second power module 142 located in the clearance space 1211 at a distance from the inner wall of the clearance space 1211. This reduces the risk of the second power module 142 interfering with the operation of the wind turbine 121, improves the smoothness of the operation of the wind turbine 121, and thus helps to ensure the efficiency of the wind turbine 121 in driving airflow.

[0083] Combination Figure 3 and Figure 6 In some embodiments of this utility model, on the axial direction of the wind turbine 121, the distance between any side of the portion of the second power module 142 located in the clearance space 1211 and the clearance space 1211 is a first distance S1, where S1 > 8 mm.

[0084] Considering that the second power module 142 is prone to move in the axial direction of the impeller 121 when the air handling equipment 100 shakes, by making S1 > 8mm, sufficient movement space is reserved for the second power module 142 in the axial direction of the impeller 121. This helps to further reduce the risk of the second power module 142 contacting the inner wall of the clearance space 1211, thereby further reducing the risk of the second power module 142 interfering with the operation of the impeller 121.

[0085] Combination Figure 3 and Figure 6 In some embodiments of this utility model, in the radial direction of the impeller 121, the distance between the portion of the second power module 142 located in the clearance space 1211 and the clearance space 1211 is the second distance S2, where S2 > 8 mm.

[0086] Considering that the second power module 142 may move in the radial direction of the impeller 121 when the air handling equipment 100 shakes, by making S2 > 8mm, sufficient movement space is reserved for the second power module 142 in the radial direction of the impeller 121. This helps to further reduce the risk of the second power module 142 contacting the inner wall of the clearance space 1211, thereby further reducing the risk of the second power module 142 interfering with the operation of the impeller 121.

[0087] Combination Figure 1 and Figure 4 In some embodiments of the present invention, at least a portion of the first power board 1421 is located in the clearance space 1211, and the surface of the first power board 1421 located in the clearance space 1211 facing the wind turbine 121 is formed as an arc surface matching the wind turbine 121.

[0088] For example, the clearance space 1211 is provided on the outer peripheral wall of the impeller 121, and the clearance space 1211 extends along the circumferential direction of the impeller 121. In the radial direction of the impeller 121, the surface of the first power board 1421 opposite to the impeller 121 is formed into an arc surface with the same shape as the outer peripheral wall of the impeller 121, so as to facilitate the arrangement of the first power board 1421 in the clearance space 1211, which is beneficial to improving the effect of saving the space required to arrange the first power board 1421.

[0089] It should be noted that "the outer peripheral wall of the impeller 121" refers to the side wall of the impeller 121 that is opposite to the housing 110 in the radial direction.

[0090] Combination Figure 1 and Figure 4 In some embodiments of this utility model, in the radial direction of the impeller 121, the surface of the first power board 1421 away from the impeller 121 matches the shape of the inner peripheral wall of the housing 110.

[0091] It should be noted that "the inner peripheral wall of the housing 110" refers to the side wall of the housing 110 opposite to the wind turbine 121 in the radial direction of the wind turbine 121.

[0092] For example, the housing 110 can be formed in a cylindrical shape, and correspondingly, the inner peripheral wall of the housing 110 is formed in an arc-shaped wall. In the radial direction of the impeller 121, the surface of the first power board 1421 opposite to the housing 110 is formed in an arc shape with the same shape as the inner peripheral wall of the housing 110, so as to achieve the shape matching between the surface of the first power board 1421 away from the impeller 121 and the inner peripheral wall of the housing 110. This is beneficial to increase the area of ​​the first power board 1421 while improving the effect of saving the space required to arrange the first power board 1421.

[0093] Combination Figures 1 to 3 In a further embodiment of the present invention, the impeller 121 can be a centrifugal impeller, the clearance space 1211 is located on the outer peripheral wall of the impeller 121, and the second power module 142 is located on the radial side of the impeller 121 and at the air outlet end of the centrifugal impeller.

[0094] The centrifugal impeller has an axial air intake and a radial air outlet. The clearance space 1211 is set on the outer peripheral wall of the impeller 121 and is recessed along the radial direction of the impeller 121. That is, the clearance space 1211 is located at the air outlet end of the impeller 121. At least part of the second power module 142 is located in the clearance space 1211, so that the second power module 142 can be arranged at the air outlet end of the impeller 121, which facilitates the air discharged from the impeller 121 to flow through the second power module 142, thereby facilitating the heat dissipation of the second power module 142 and the assembly of the second power module 142, which is beneficial to improving the production and assembly efficiency of the air handling equipment 100.

[0095] Combination Figures 1 to 3 In some embodiments of the present invention, in the radial direction of the wind turbine 121, the radially outer ends of some blades of the wind turbine 121 are recessed toward the rotation axis of the wind turbine 121 to define a clearance space 1211.

[0096] Specifically, the impeller 121 is a centrifugal impeller, and the clearance space 1211 is set at the air outlet end of the impeller 121. That is, at least part of the clearance space 1211 is located in the air outlet area of ​​the blade. In the radial direction of the impeller 121, the radial dimension of the part of the blade directly opposite the clearance space 1211 is smaller than the radial dimension of the part of the blade not directly opposite the clearance space 1211. Thus, by designing the blades of the impeller 121, a clearance space 1211 that is recessed in the radial direction of the impeller 121 can be formed on the impeller 121, which facilitates the placement of the second power module 142 in the clearance space 1211, realizing the integration of the second power module 142 with the impeller 121, and facilitating the dissipation of the second power module 142 by the air discharged from the impeller 121.

[0097] Combination Figures 1 to 3In some embodiments of the present invention, the air handling device 100 further includes a heating element 180, which is configured to heat the air to achieve the heating function of the air handling device 100. A portion of the impeller 121 is located inside the heating element 180, and the clearance space 1211 is located outside the heating element 180.

[0098] For example, in the axial direction of the impeller 121, a portion of the impeller 121 extends into the heating element 180, and another portion of the impeller 121 extends out of the heating element 180. In the radial direction of the impeller 121, the impeller 121 and the heating element 180 can be spaced apart to prevent the heating element 180 from interfering with the operation of the impeller 121 and to ensure the smooth operation of the impeller 121. At the same time, since a portion of the impeller 121 is located inside the heating element 180, it is beneficial to improve the guiding effect of the impeller 121 on the air inside the heating element 180, thereby improving the heat dissipation efficiency of the air to the heating element 180.

[0099] The clearance space 1211 is provided on a portion of the impeller 121 located outside the heating element 180, so that at least a portion of the second power module 142 can be located within the clearance space 1211. In other words, it facilitates the arrangement of the second power module 142 outside the heating element 180, which helps to prevent the second power module 142 from being unable to be installed due to insufficient space inside the heating element 180. At the same time, it allows the second power module 142 to be located away from the heating element 180, reducing the impact of the heat generated by the heating element 180 on the second power module 142, thereby helping to reduce the risk of the second power module 142 overheating.

[0100] In some embodiments of this invention, the heating element 180 is configured to generate heat under the influence of a magnetic field.

[0101] For example, in the radial direction of the impeller 121, the electromagnetic coil is arranged on the radial outer side of the heating element 180. By matching the electromagnetic coil with the heating element 180, electromagnetic induction heating can be realized. Electromagnetic induction heating has the advantages of uniform heating and rapid response, which is beneficial to improving the heating efficiency of the air handling equipment 100.

[0102] Combination Figure 7 and Figure 8 In some embodiments of this utility model, blades are formed on the wind turbine 121, with a portion of the blades located on the heating element 180 and another portion located outside the heating element 180.

[0103] Specifically, some blades located inside the heating element 180 are suitable for dissipating heat from the heating element 180, while some blades located outside the heating element 180 are suitable for dissipating heat from the electromagnetic coil outside the heating element 180. The outer diameters of the blades located inside the heating element 180 and the blades located outside the heating element 180 are designed differently to optimize the heat dissipation effect of the impeller 121 on the heating element 180 and the electromagnetic coil.

[0104] In some specific embodiments of this utility model, the outer diameter of the blades located outside the heating element 180 is larger than the outer diameter of the blades located inside the heating element 180, so as to increase the heat dissipation area of ​​the blades located outside the heating element 180 on the electromagnetic coil, which is beneficial to improving the heat dissipation effect of the blades located outside the heating element 180 on the electromagnetic coil.

[0105] Combination Figure 7 and Figure 8 In some embodiments of this utility model, in the axial direction of the impeller 121, the diameter of the portion of the impeller 121 located outside the heating element 180 is D, and the diameter of the portion of the impeller 121 located inside the heating element 180 is d, where 0.5≤d / D≤0.9.

[0106] Considering that both the electromagnetic coil and the heating element 180 need to dissipate heat, the diameter D of the portion of the impeller 121 located outside the heating element 180 (which can also be understood as the outer diameter of the blades of the impeller 121 located outside the heating element 180) is made larger than the diameter d of the portion of the impeller 121 located inside the heating element 180 (which can also be understood as the outer diameter of the blades of the impeller 121 located inside the heating element 180). This allows the airflow driven by the portion of the impeller 121 located outside the heating element 180 to flow through the electromagnetic coil, thereby improving the heat dissipation effect of the impeller 121 on the electromagnetic coil, preventing the electromagnetic coil from overheating, and ensuring the heat dissipation effect of the impeller 121 on the heating element 180.

[0107] When d / D < 0.5, the heat dissipation effect of the impeller 121 on the heat source 180 is poor, or the diameter of the part of the impeller 121 located outside the heat source 180 is too large, thus increasing the size of the air handling equipment 100. When d / D > 0.9, the heat dissipation effect of the impeller 121 on the electromagnetic coil is poor, or the diameter of the part of the impeller 121 located inside the heat source 180 is too large, thus the gap between the impeller 121 and the heat source 180 is too small, affecting the air outlet effect of the impeller 121.

[0108] Combination Figures 1 to 3 In some embodiments of this utility model, the air handling device 100 further includes a coil support 141, an electromagnetic coil is fixed to the coil support 141, and the coil support 141 is formed into a ring and sleeved onto the heating element 180.

[0109] The coil support 141 is correspondingly arranged with the heating element 180, and in the radial direction of the impeller 121, the coil support 141 is located outside the heating element 180, and the heating element 180 is fixedly installed on the coil support 141. This helps to ensure the effective cooperation between the electromagnetic coil and the heating element 180, and the coil support 141 can provide stable support for the electromagnetic coil, which helps to improve the assembly stability of the electromagnetic coil.

[0110] Combination Figures 1 to 3 In some specific embodiments, the coil support 141 is formed in a ring shape and is sleeved on the heating element 180. Multiple winding protrusions 1411 are provided on the outer peripheral wall of the coil support 141. The multiple winding protrusions 1411 are arranged at intervals in the axial direction of the impeller 121. A winding groove is formed between two adjacent winding protrusions 1411. The electromagnetic coil can be set on the coil support 141 through multiple winding grooves to improve the assembly stability of the electromagnetic coil.

[0111] like Figure 3 As shown, in some embodiments of the present invention, the air handling device 100 further includes a controller 160, which is disposed in the housing 110 and electrically connected to the first power module 130 and the second power module 142 respectively.

[0112] For example, the controller 160 can receive external signals, which may be generated by manual operation by the user or from instructions from the control system. After receiving the signal, the controller 160 can control the operating status of the first power module 130 and the second power module 142. For example, the controller 160 can control the current of the first power module 130 and the second power module 142 or control the opening and closing of the first power module 130 and the second power module 142, thereby controlling the operating status of the air handling equipment 100.

[0113] Reference Figure 3 The controller 160 is located adjacent to the first power module 130. Considering that the first power module 130 is small in size and occupies little space, there is enough space to install the controller 160 in the position adjacent to the first power module 130. Therefore, by setting the controller 160 adjacent to the first power module 130, it is beneficial to further improve the space utilization of the air handling equipment 100 and to realize the miniaturization design of the air handling equipment 100.

[0114] Combination Figure 2 and Figure 3In a further embodiment of this utility model, a wire passage groove is also provided on the side of the housing 110 where the air outlet 112 is formed. The wire passage groove can extend from the center position of the side of the housing 110 where the air outlet 112 is formed along the radial direction of the impeller 121 towards the first power module 130. The wire harness that is electrically connected to the first power module 130 and the motor 122 can be arranged in the wire passage groove. At the same time, since the controller 160 is located near the first power module 130, the wire harness led out from the controller 160 can also be arranged in the wire passage groove. Thus, it is convenient to position the wire harness and improves the regularity of the wire harness in the air handling equipment 100.

[0115] Reference Figure 3 In some other embodiments of this utility model, the controller 160 can be spaced apart from the first power module 130, that is, the controller 160 and the first power module 130 can be located on both sides of the impeller 121 in the radial direction. Under this structure, the side of the housing 110 where the air outlet 112 is formed can be provided with a first wire groove 117 and a second wire groove 118 respectively.

[0116] The first wire passage 117 extends from the center of the side of the housing 110 where the air outlet 112 is formed along the radial direction of the impeller 121 towards the first power module 130. The wire harness led out from the first power module 130 can be placed in the first wire passage 117. The second wire passage 118 extends from the center of the side of the housing 110 where the air outlet 112 is formed along the radial direction of the impeller 121 towards the controller 160. The wire harness led out from the controller 160 can be placed in the second wire passage 118, so as to facilitate wiring of the first power module 130 and the controller 160 respectively, and to improve the neatness of the wire harness in the air handling equipment 100.

[0117] In some embodiments of this utility model, the air handling equipment 100 further includes a shielding component, which is disposed between the outer side of the electromagnetic module 140 and the housing 110, and the shielding component is made of magnetic material.

[0118] Considering that 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 180 in the radial direction of the impeller 121, causing magnetic field leakage, a shielding component is set between the electromagnetic module 140 and the housing 110 to reduce the amount of magnetic field leakage on the side of the electromagnetic coil away from the heating element 180. This also helps to increase the magnetic field strength on the side of the electromagnetic coil close to the heating element 180, thereby improving the heating effect of the heating element 180 and thus improving the heating efficiency of the air handling equipment 100.

[0119] In the radial direction of the impeller 121, the shielding component can be set on the side of the electromagnetic coil away from the heating element 180, which helps to ensure the shielding effect of the shielding component on the magnetic field of the electromagnetic coil away from the heating element 180.

[0120] It should be noted that the magnetic materials can be neodymium iron boron permanent magnets, ferrite permanent magnets, silicon steel, metal soft magnetic powder cores, and ferrite soft magnets, etc.

[0121] Combination Figure 1 , Figure 3 , Figure 4 and Figure 5 In some embodiments of this utility model, the air handling equipment 100 further includes a fixing bracket 170, which is disposed inside the housing 110 and is used to fix the shielding component.

[0122] For example, a mounting groove 172 is formed on the mounting bracket, and the shielding component can be embedded in the mounting groove 172 so that the shielding component can be fixed to the mounting bracket 170. In addition, the first power module 130 and the second power module 142 can be spaced apart on the mounting bracket 170, and the first power module 130 and the second power module 142 can be fixedly connected to the mounting bracket 170 respectively by threaded connectors (such as screws). After the shielding component, the first power module 130 and the second power module 142 are assembled with the mounting bracket 170 respectively, the mounting bracket 170 can be fixedly connected to the housing 110, thereby realizing the modular assembly of the shielding component, the first power module 130, the second power module 142 and the mounting bracket 170, which is beneficial to improving the assembly convenience of the air handling equipment 100.

[0123] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the fixed bracket 170 is provided with a through hole 171 for accommodating the first power module 130.

[0124] For example, the through hole 171 penetrates the fixed bracket 170 in the thickness direction. The through hole 171 can avoid the first power module 130, so that the first power module 130 can be placed in the through hole 171 to realize the integrated assembly of the first power module 130 and the fixed bracket 170. This is beneficial to improve the assembly convenience of the air handling equipment 100 and to reduce the space occupied by the first power module 130, thereby facilitating the miniaturization design of the air handling equipment 100.

[0125] Combination Figure 4 and Figure 5In some specific embodiments, in the axial direction of the impeller 121, a flow guiding structure 173 can be provided on the side of the fixed bracket 170 near the air inlet 111, and the flow guiding structure 173 can extend along the circumferential direction of the fixed bracket 170. The flow guiding structure 173 can guide the air entering from the air inlet 111 to the heating element 180, which is beneficial to improving the efficiency of airflow to the heating element 180.

[0126] Furthermore, a through hole 171 is formed on the flow guiding structure 173. The through hole 171 can avoid the first power module 130, so that the first power module 130 can be placed in the through hole 171. At the same time, in the projection plane of the impeller 121 in the axial direction, the orthographic projection area of ​​the flow guiding structure 173 is smaller than the orthographic projection area of ​​the fixed bracket 170. The second power module 142 is staggered with the flow guiding structure 173, so as to achieve the second power module 142 and the first power module 130 being spaced apart, while preventing the second power module 142 and the flow guiding structure 173 from interfering with each other, ensuring that the second power module 142 can be installed on the fixed bracket 170.

[0127] Optionally, the first power module 130 and the second power module 142 can be arranged opposite to each other and spaced apart in the radial direction of the impeller 121, which helps to ensure the effect of the first power module 130 and the second power module 142 being spaced apart, thereby helping to ensure the electrical control reliability of the air handling equipment 100.

[0128] In some embodiments of this utility model, the first power module 130 includes a second power board 131 and a second component 132. The second power board 131 is disposed on a fixed bracket 170, and the second component 132 is disposed on the side of the second power board 131 away from the impeller 121 and extends out of the fixed bracket 170 through a through hole 171.

[0129] For example, the second component 132 is mounted on the second power board 131. The second power board 131 can be mounted at the position of the through hole 171 of the fixing bracket 170 via a threaded connector, thereby fixing the first power module 130 on the fixing bracket 170. Considering that the heat generated by the second component 132 on the first power module 130 is small, there is no need to dissipate heat from the air discharged by the fan 121. Therefore, the second component 132 can be placed on the side of the second power board 131 away from the fan 121 to reduce the heat generated by the first power module 130. The risk of interference from the second component 132 to the air is reduced, which helps to ensure that the air entering the housing 110 from the air inlet 111 can flow smoothly to the electromagnetic coil located radially inside the fixed bracket 170. This reduces the interference of the second component 132 to the airflow to the electromagnetic coil and ensures the heat dissipation effect of the air on the electromagnetic coil. At the same time, it can reduce the interference of the second component 132 to the airflow discharged from the part of the fan wheel 121 located outside the heat source 180, ensuring the effect of the air discharged from the fan wheel 121 flowing to the electromagnetic coil, thereby further improving the heat dissipation efficiency of the electromagnetic coil.

[0130] Combination Figures 1 to 3 In some embodiments of this utility model, the housing 110 includes a housing body 114, on which an air inlet 111 and an air outlet 112 are formed respectively. The heating element 180, electromagnetic module 140, fan 120 and first power module 130 and other structures can be arranged inside the housing body 114. The housing body 114 can provide positioning support for the structures arranged therein, which is beneficial to improving the structural stability of the air handling equipment 100. In addition, the housing body 114 can protect the above-mentioned structures, which is beneficial to reducing the risk of damage to the fan 120 and other structures, thereby improving the service life of the air handling equipment 100.

[0131] Combination Figures 1 to 3 In some embodiments of this utility model, an air inlet screen 115 is provided at the air inlet 111 of the shell body 114. The air inlet screen 115 is detachably mounted on the shell body 114 so that the user can remove the air inlet screen 115 for cleaning, and at the same time facilitate the cleaning and maintenance of the structure inside the shell body 114.

[0132] In some embodiments of this utility model, when the air handling device 100 is actually used, the air inlet 111 is located on the rear side of the housing 110, and the air outlet 112 is located on the front side of the housing 110. That is to say, the air handling device 100 takes in air from the rear side and outputs airflow forward.

[0133] The following describes two assembly methods of the air handling equipment 100 based on the structure of the air handling equipment 100 according to an embodiment of the present invention.

[0134] Assembly Method 1: The heating element 180 is fixedly connected to the coil support 141. The first power module 130 and the shielding component are fixedly installed on the fixed bracket 170. The fixed bracket 170 is sleeved on the radial outer side of the coil support 141 and fixedly connected to the coil support 141. The impeller 121 can be positioned in the center area of ​​the heating element 180 by hand. The second power module 142 is arranged in the clearance space 1211 and fixedly connected to the fixed bracket 170. This realizes the modular assembly of the heating element 180, the coil support 141, the first power module 130, the second power module 142, the shielding component, the fixed bracket 170, and the impeller 121. Then, the above components are placed into the shell body 114, and the coil support 141 is further fixedly connected to the shell body 114, and the impeller 121 is connected to the shell body 114. Finally, the air inlet mesh cover 115 is installed at the air inlet 111 of the shell body 114 to complete the assembly of the air handling equipment 100.

[0135] In order to ensure the assembly reliability of the components inside the shell body 114 with the shell body 114, the fixing bracket 170 can be further connected to the shell body 114 to reduce the possibility of the components inside the shell body 114 falling off the shell body 114.

[0136] Assembly Method 2: First, the heating element 180 is fixedly installed inside the shell body 114. Then, the coil bracket 141 is fitted onto the radial outer side of the heating element 180 and fixedly connected to the shell body 114. Next, the fixing bracket 170 is fitted onto the radial outer side of the coil bracket 141 and fixedly connected to the shell 110. Then, the impeller 121 is positioned in the central area of ​​the heating element 180. The second power module 142 can be installed on the fixing bracket 170 or the shell body 114. Finally, the air inlet mesh cover 115 is installed at the air inlet 111 of the shell body 114.

[0137] The first power module 130 can be pre-installed on the fixed bracket 170, which helps to improve the assembly convenience of the first power module 130 and the fixed bracket 170.

[0138] Optionally, all of the above-mentioned fixed connection methods can use threaded connectors to fix the components together, so as to facilitate the disassembly, maintenance and cleaning of the air handling equipment 100. Of course, it is understood that the fixed connection method includes, but is not limited to, connecting with threaded connectors, or snap-fit ​​connection, etc. The specific fixed connection method can be determined according to the actual production requirements, and no specific limitation is made here.

[0139] like Figure 9As shown, the heater 200 according to an embodiment of the present utility model includes the air handling device 100 described above. The air handling device 100 also includes a heating element 180, a fan wheel 121 adapted to drive airflow, the heating element 180 used to heat the air flowing through it, and the air adapted to be discharged from the air outlet 112.

[0140] For example, air can enter the housing 110 through the air inlet 111. The impeller 121 operates to drive the airflow into the housing 110. When the air flows through the heating element 180, the heat generated by the heating element 180 can heat the air. The heated air can then flow further to the air outlet 112 and be discharged from the housing 110 through the air outlet 112, thereby realizing the function of the air handling equipment 100 outputting hot air, and thus realizing the function of the heater 200 outputting hot air.

[0141] Since the heater 200 is equipped with the aforementioned air handling unit 100, the arrangement of the first power module 130 and the second power module 142 at intervals improves the electrical control reliability of the air handling unit 100. At the same time, the space occupied by the separate arrangement of the first power module 130 and the second power module 142 is smaller than that occupied by the integrated arrangement of the first power module 130 and the second power module 142, which improves the space utilization rate within the housing 110. This facilitates the miniaturization design of the air handling unit 100, and consequently, the miniaturization design of the heater 200.

[0142] In some embodiments of this utility model, the heating element 180 can be configured to generate heat under the action of a magnetic field, which is beneficial to improving the heating efficiency of the air handling equipment 100. In other embodiments, the heating element 180 can also be constructed as a component that generates heat after being energized. For example, the heating element 180 can be constructed as a PTC heating element, which eliminates the need to set up structures such as electromagnetic coils in the air handling equipment 100, thus simplifying the structure of the air handling equipment 100.

[0143] Reference Figure 9 In some embodiments of this utility model, the heater 200 also includes a bracket 210, and the air handling unit 100 is swayably mounted on the bracket 210.

[0144] The heater 200 also includes a base 220, and a bracket 210 is rotatably connected to the base 220. The base 220 is also provided with a drive device, which can drive the bracket 210 to swing in the left and right direction relative to the base 220. The bracket 210 can form an installation space. The inner wall of the installation space is provided with a connecting part. The air handling unit 100 is rotatably connected to the connecting part and accommodated in the installation space. For example, the connecting part of the bracket 210 clamps the air handling unit 100 in the left and right direction and drives the air handling unit 100 to swing up and down.

[0145] Optionally, the vertical swing of the air handling unit 100 can also be in the form of a guide rail. Alternatively, the bracket 210 can be mounted on the base 220, and the drive device can be mounted on the bracket 210 and connected to the air handling unit 100 for transmission, so as to drive the air handling unit 100 to swing up and down or left and right.

[0146] The drive unit can be configured as a drive motor.

[0147] In some embodiments of this utility model, the first power module 130 is disposed on the bracket 210 and the second power module 142 is disposed inside the housing 110.

[0148] By placing the first power module 130 on the bracket 210, the installation space inside the housing 110 is avoided, which saves space inside the housing 110 for arranging other components (such as the heating element 180). By placing the second power module 142 inside the housing 110, the wiring harness for connecting the second power module 142 can be arranged inside the housing 110. When the air handling equipment 100 swings relative to the bracket 210, the wiring harness, the electromagnetic module 140, and the housing 110 can swing synchronously, which reduces the risk of the wiring harness cutting the magnetic field due to its movement relative to the electromagnetic coil, thereby reducing the risk of excessive heat generation of the electromagnetic coil.

[0149] In some embodiments of this utility model, the heater 200 has a cold air operation mode and a warm air operation mode, which allows the heater 200 to provide suitable air output according to the user's needs, thereby improving the functionality of the heater 200.

[0150] When the heater 200 is in cold air operation mode, the fan wheel 121 starts and the heating element 180 works at the same time to ensure that the heater 200 can provide clean cold air, so that the heater 200 can be used to cool down high-temperature environments, and at the same time, it helps to reduce the energy consumption of the heater 200.

[0151] When the heater 200 is in the warm air operation mode, the fan wheel 121 and the heating element 180 work simultaneously to ensure that the heater 200 can output hot air, so that the heater 200 can be used to heat the environment with low temperature.

[0152] In some embodiments, the cold air operation mode of the heater 200 needs to ensure that the output air speed of the heater 200 is high enough. That is, the number of speed settings in the cold air operation mode of the heater 200 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 200 can have 8 speed settings in the cold air mode and 3 speed settings in the warm air mode. When the heater 200 switches directly from the 3rd speed setting in the cold air mode to the warm air mode, the heater 200 operates at the maximum speed setting (i.e., the third speed setting) in the warm air mode, and the heater 200 outputs the hot air most efficiently.
