[0047] Figure 1 This is a schematic structural diagram of a cross-flow wind turbine according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 6 This utility model provides a cross-flow fan for an air conditioner. The cross-flow fan includes a fan body 100, two annular grooves 200, and two closures 300.

[0048] The wind turbine body 100 has two mounting bases 110 and multiple blades 120 located between the two mounting bases 110. Each blade 120 is provided with a refrigerant passage 121.

[0049] Two annular grooves 200 are respectively disposed on the peripheral walls of two mounting bases 110, or disposed on the peripheral wall of the same mounting base 110. The two annular grooves 200 are connected by a refrigerant channel 121, so that the refrigerant in one annular groove 200 enters the other annular groove 200 through the refrigerant channel 121.

[0050] Each closure 300 seals an annular groove 200. Each closure 300 is provided with a refrigerant inlet 310.

[0051] Each closure 300 is rotatably disposed on the peripheral wall of the corresponding mounting base 110. Alternatively, the blade 120 is rotatably disposed on the mounting base 110 relative to the mounting base 110, and each closure 300 is fixedly connected to the corresponding mounting base 110.

[0052] In this embodiment, the refrigerant enters the annular groove 200 through the refrigerant inlet 310 of one sealing member 300, then flows through the refrigerant channel 121 in the blade 120 to another annular groove 200, and finally flows out from the refrigerant inlet 310 of the other sealing member 300. During this process, because the refrigerant passes through the blade 120 through the refrigerant channel 121, a temperature difference exists between the blade 120 and the airflow before it passes through the blade 120, thereby achieving heat exchange of the airflow after it passes through the blade 120.

[0053] When the cross-flow fan is working, it not only guides the airflow from the air inlet to the air outlet, but also exchanges heat with the airflow. Moreover, when the blades 120 with refrigerant passage 121 rotate to guide the airflow, the airflow comes into full contact with the blades 120, resulting in a high heat exchange efficiency between the airflow and the refrigerant. This improves the heat exchange efficiency of the air conditioner and enhances the user experience.

[0054] Furthermore, the combined effect of the refrigerant-containing blades 120 and the evaporator can further improve the heat exchange efficiency of the airflow, thereby improving the quality of the air conditioner and enhancing the user experience.

[0055] In some embodiments of the cross-flow wind turbine of this utility model, such as Figure 3 As shown, each refrigerant channel 121 extends along the length direction of the corresponding blade 120, and multiple refrigerant channels 121 are provided on each blade 120. The multiple refrigerant channels 121 are arranged sequentially along the width direction of the corresponding blade 120, and each refrigerant channel 121 penetrates the corresponding blade 120.

[0056] In this embodiment, each blade 120 is provided with multiple refrigerant channels 121. The refrigerant enters the interior of the blade 120 through multiple refrigerant channels 121, so that the distribution of the refrigerant in the refrigerant channels 121 is more uniform. Moreover, the design of multiple refrigerant channels 121, compared with a single large refrigerant channel 121, reduces the possibility of refrigerant stagnation in the refrigerant channel 121 after participating in heat exchange, which affects the heat exchange efficiency. In other words, the flow of refrigerant in the smaller refrigerant channel 121 is more stable, effectively improving the heat exchange efficiency of airflow and refrigerant.

[0057] In some embodiments of the cross-flow wind turbine of this utility model, such as Figure 2 and Figure 3 As shown, the wind turbine body 100 also includes two mounting plates 130.

[0058] The two ends of the blade 120 are respectively fixed on two mounting plates 130.

[0059] Each mounting base 110 is located on the outer side of the mounting plate 130. For example... Figure 4 and Figure 5 As shown, a plurality of refrigerant grooves 111 are provided on the inner surface of the mounting base 110. Each refrigerant groove 111 is connected to the annular groove 200 through a connecting hole 112. Each refrigerant groove 111 is correspondingly provided with a blade 120 so that the refrigerant groove 111 is connected to the refrigerant channel 121 on the corresponding blade 120.

[0060] In this embodiment, each blade 120 is connected to two spaced mounting plates 130 at both ends along the length of the refrigerant channel 121, thereby improving the overall structural strength of the wind turbine body 100.

[0061] During the operation of the cross-flow fan, the refrigerant enters the annular groove 200 from the refrigerant inlet 310, then enters the refrigerant tank 111 through the connecting hole 112, and then enters the blade 120 through the refrigerant channel 121.

[0062] Preferably, the refrigerant channel 121 extends through the mounting plate 130 along its length so that the refrigerant channel 121 is directly connected to the refrigerant tank 111.

[0063] In some embodiments of the cross-flow fan of this utility model, each mounting plate 130 is rotatably disposed relative to the mounting base 110, and each closure 300 is fixedly connected to the corresponding mounting base 110.

[0064] In this embodiment, the sealing member 300 is fixedly connected to the mounting base 110, making the connection structure between the sealing member 300 and the mounting base 110 more stable, improving the sealing performance during refrigerant transmission, and thus making the refrigerant transmission more stable. The sealing member 300 is connected to the refrigerant supply equipment through a pipe. The sealing member 300 is fixedly installed in the air duct, which can avoid pipe entanglement or damage caused by the movement of the sealing member 300. The blade 120 rotates along the axis of the impeller body 100, that is, the blade 120 rotates relative to the mounting base 110 to meet the air supply needs of the air conditioner. Since the mounting plate 130 is fixedly installed with the blade 120, the mounting plate 130 rotates relative to the mounting base 110 under external force, so that the blade 120 can rotate synchronously with the mounting plate 130. While ensuring that the refrigerant transmission channel is not easily damaged or leaked, the simple structural design also meets the working requirements of the blade 120's rotation, ensuring the normal operation of the air conditioner.

[0065] Furthermore, when heat exchange is not required using an air conditioner, the relative rotation of the mounting plate 130 and the mounting base 110 can cause the openings of the refrigerant tank 111 and the refrigerant channel 121 on the mounting plate 130 to be misaligned, preventing refrigerant from entering the refrigerant channel 121 and further improving the sealing performance during the refrigerant transfer process.

[0066] In some embodiments of the cross-flow fan wheel of this utility model, the mounting plate 130 is coaxially arranged and fixedly connected with the motor output shaft.

[0067] In some embodiments of the cross-flow fan impeller of this utility model, each closure 300 is rotatably disposed on the peripheral wall of the corresponding mounting base 110, and a limiting device 400 is provided between the mounting plate 130 and the mounting base 110. The limiting device 400 is configured to keep the mounting plate 130 and the mounting base 110 in the current position after the relative position of the mounting plate 130 relative to the mounting base 110 changes.

[0068] In this embodiment, the sealing element 300 is connected to the refrigerant supply equipment via a pipe. The sealing element 300 is fixedly installed within the air duct, which can prevent pipe entanglement or damage caused by the movement of the sealing element 300. The blade 120 rotates along the axis of the impeller body 100, that is, the blade 120 rotates relative to the sealing element 300 to meet the air supply needs of the air conditioner. Since the mounting plate 130 is fixedly installed with the blade 120, the mounting plate 130 rotates relative to the mounting base 110 under external force, so that the blade 120 can rotate synchronously with the mounting plate 130, meeting the working requirements of the blade 120 rotation and ensuring the normal operation of the air conditioner.

[0069] Mounting base 110 can rotate relative to closure 300. At the same time, mounting plate 130 and mounting base 110 can also rotate relative to each other, and the relative positions of mounting plate 130 and mounting base 110 can be locked by limiting device 400.

[0070] Furthermore, the limiting device 400 is configured such that when the refrigerant groove 111 on the mounting base 110 is aligned with all or part of the refrigerant channel 121 on the corresponding blade 120, the mounting plate 130 and the mounting base 110 remain in the current position, that is, the relative position of the mounting plate 130 and the mounting base 110 is locked so that the number of refrigerant grooves 111 and refrigerant channels 121 aligned remains unchanged.

[0071] Alternatively, the limiting device 400 can be configured to have multiple locking positions for the mounting plate 130 and the mounting base 110. Since different locking positions will result in different flow rates of refrigerant entering the refrigerant channel 121, the flow rate of refrigerant can be controlled by setting different locking positions.

[0072] In some embodiments of the cross-flow wind turbine of this utility model, such as Figure 6 As shown, the limiting device 400 includes an adjusting post 410, at least two adjusting holes 420, and an elastic device.

[0073] The adjusting column 410 is slidably mounted on the mounting plate 130.

[0074] At least two adjustment holes 420 are provided on the inner surface of the mounting base 110, and the adjustment post 410 is inserted into one adjustment hole 420.

[0075] The elastic device is configured to provide a force that causes the adjusting post 410 to insert into the adjusting hole 420.

[0076] In this embodiment, the adjusting column 410 is slidably connected to the mounting plate 130 along the axial direction of the adjusting hole 420. An elastic device applies a force to the adjusting column 410, causing it to insert into the adjusting hole 420. When the mounting plate 130 rotates relative to the mounting base 110 to a position where the adjusting column 410 can engage with the adjusting hole 420, the adjusting column 410, under the action of the elastic device, inserts into the adjusting hole 420, restricting the relative rotation between the mounting plate 130 and the mounting base 110, thus locking the position between them. When it is necessary to change the relative position between the mounting plate 130 and the mounting base 110, an external force can be applied to overcome the force exerted by the elastic device on the adjusting column 410, allowing the adjusting column 410 to disengage from the current adjusting hole 420, thus removing the obstruction between the mounting plate 130 and the mounting base 110, and enabling relative rotation between them. This structure achieves a self-locking function after the angle of the mounting plate 130 is adjusted through a mechanical limiting method, ensuring the positioning stability of the mounting plate 130 and the mounting base 110 during the operation of the cross-flow fan.

[0077] In some embodiments of the cross-flow wind turbine of this utility model, such as Figure 6 As shown, each closure 300 has flanges 320 at both ends, and a mounting base 110 and a mounting plate 130 corresponding to the closure 300 are located between the two flanges 320. Anti-rotation holes 321 are provided on both inner flanges 320. One of the mounting bases 110 is connected to a drive assembly.

[0078] The cross-flow wind turbine also includes two electromagnets.

[0079] Two electromagnets are respectively mounted on the two inner flanges 320. Each electromagnet is configured to cause the corresponding adjusting pin 410 to disengage from the adjusting hole 420 and enter the corresponding anti-rotation hole 321.

[0080] In this embodiment, the sealing member 300 has flanges 320 at both ends, which axially constrain the corresponding mounting base 110 and mounting plate 130 between the two flanges 320, which not only improves the sealing strength, but also enhances the installation firmness of the mounting base 110, mounting plate 130 and sealing member 300.

[0081] The inner flange 320 is provided with an anti-rotation hole 321 to form a clearance space for the adjusting column 410 when it is not necessary to restrict the relative rotation of the mounting base 110 and the mounting plate 130.

[0082] The electromagnet can drive the adjusting pin 410 to disengage from the adjusting hole 420. When the electromagnet is energized, it generates magnetic force, causing the corresponding adjusting pin 410 to overcome the elastic force of the elastic device, disengage from the adjusting hole 420 on the mounting base 110, and enter the anti-rotation hole 321 on the flange 320. This ensures that the relative rotation of the mounting base 110 and the mounting plate 130 shaft is not interfered with, while also restricting the relative rotation of the sealing member 300 and the mounting base 110.

[0083] The drive assembly drives the mounting base 110 to rotate, thereby enabling the air conditioner to deliver air. When refrigerant flow needs adjustment, the electromagnet is energized to pull the adjusting column 410 out of the adjusting hole 420 and insert it into the anti-rotation hole 321. The drive assembly controls the relative rotation of the mounting base 110 and the mounting plate 130 along the axis, so that the refrigerant channel 111 and the blades 120 are in the appropriate alignment position. The refrigerant flow is controlled by the difference in the overlapping area of ​​the refrigerant channel 111 and the blades 120. When the refrigerant flow is adjusted or when no adjustment is needed, the electromagnet is not working, and the adjusting column 410 is inserted in the adjusting hole 420, restricting the relative rotation of the mounting plate 130 and the mounting base 110. When the blades 120 need to rotate, the drive assembly rotates the mounting base 110. Because the adjusting column 410 restricts the relative rotation of the mounting base 110 and the mounting plate 130, the mounting plate 130 rotates synchronously when the mounting base 110 rotates, thereby causing the blades 120 to rotate and deliver air.

[0084] The structure of unlocking and relocking between the mounting base 110 and the mounting plate 130 controlled by an electromagnet is simple and easy to operate.

[0085] In some embodiments of the cross-flow wind turbine of this utility model, such as Figure 2 As shown, each mounting plate 130 is provided with two first annular seals 510 between it and the corresponding mounting base 110, and the refrigerant tank 111 is located between the two first annular seals 510.

[0086] In this embodiment, two first annular seals 510 are provided between the mounting plate 130 and the corresponding mounting base 110, and the refrigerant tank 111 is precisely defined within the sealing space between the two first annular seals 510. The first annular seals 510 ensure the sealing of the refrigerant flow in the refrigerant tank 111, effectively preventing refrigerant leakage and maintaining stable system pressure, thus ensuring the stability of the refrigerant flow in the refrigerant channel 121 during the heat exchange process of the cross-flow fan.

[0087] In some embodiments of the cross-flow wind turbine of this utility model, such as Figure 2 As shown, each closure 300 is provided with two second annular seals 520 between it and the corresponding mounting base 110, and the annular groove 200 is located between the two second annular seals 520.

[0088] In this embodiment, two second annular seals 520 are provided between the sealing member 300 and the corresponding mounting base 110, and the annular groove 200 is sealed within the sealed area formed by the two second annular seals 520. The second annular seals 520 ensure the sealing effect of the annular groove 200 area, effectively prevent refrigerant leakage and maintain stable system pressure, and ensure the stability of refrigerant flow in the refrigerant channel 121 during the heat exchange process of the cross-flow fan.

[0089] In some embodiments of the cross-flow wind turbine of this utility model, among the multiple refrigerant channels 121 on each blade 120, the cross-sectional area of ​​the refrigerant channel 121 located on the outer side is smaller than the cross-sectional area of ​​the refrigerant channel 121 located on the inner side.

[0090] In this embodiment, the outer side of the blade 120 is mainly used for air guidance. The smaller cross-sectional area of ​​the refrigerant channel 121 on the outer side can ensure the structural strength of the outer side of the blade 120. The larger cross-section on the inner side can reduce the refrigerant flow resistance and ensure the supply of refrigerant. This ensures both the overall heat exchange performance of the air conditioner and the structural strength of the impeller body 100.

[0091] This utility model also provides an air conditioner. In some embodiments of the air conditioner of this utility model, the air conditioner includes any of the cross-flow fan impellers described above.

[0092] In this embodiment, the refrigerant enters the annular groove 200 through the refrigerant inlet 310 of one sealing member 300, then flows through the refrigerant channel 121 in the blade 120 to another annular groove 200, and finally flows out from the refrigerant inlet 310 of the other sealing member 300. During this process, because the refrigerant passes through the blade 120 through the refrigerant channel 121, a temperature difference exists between the blade 120 and the airflow before it passes through the blade 120, thereby achieving heat exchange of the airflow after it passes through the blade 120.

[0093] When the air conditioner is working, the cross-flow fan not only guides the airflow from the air inlet to the air outlet, but also exchanges heat with the airflow. Moreover, when the blades 120 with refrigerant passage 121 rotate to guide the airflow, the airflow comes into full contact with the blades 120, resulting in a high heat exchange efficiency between the airflow and the refrigerant. This improves the heat exchange efficiency of the air conditioner and enhances the user experience.

[0094] Furthermore, the combined effect of the refrigerant-containing blades 120 and the evaporator can further improve the heat exchange efficiency of the airflow, thereby improving the quality of the air conditioner and enhancing the user experience.

[0095] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
