Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to a water wheel for two-way water injection and an air conditioner having the same. Background Art

[0002] For the mobile air conditioners on the market, water wheels are added between every two groups of condenser fins for condenser heat dissipation, so that the condensed water is injected onto the condenser, thereby achieving the purpose of cooling. Generally, the water wheel is a plastic part, and the demolding direction of its round hole structure is in one direction, so that the water injection direction can only be in one direction and cannot take into account two groups of condensers, which is very uneven. In order to optimize the heat dissipation effect, some water injection devices with two-way water injection functions have emerged on the market. For example, some water injection devices are respectively provided with water receiving grooves or water injection vanes on the left and right surfaces of the water wheel to perform two-way water injection by using a single water wheel. Some other water injection devices are provided with two water wheels with single-direction water injection and opposite water injection directions between two groups of condensers to perform two-way water injection by using two water wheels.

[0003] However, for the water injection devices adopting the scheme of respectively arranging water receiving grooves or water injection vanes on the left and right surfaces of the water wheel, the two-way water injection structure is complex, and there are problems of high production cost, low assembly efficiency and poor structural stability. In addition, for the water injection devices adopting the scheme of arranging two water wheels with single-direction water injection and opposite water injection directions, the space occupied by the two single-direction water injection water wheels is significantly more than the space occupied by a single water wheel, the space utilization rate is low, and there are also problems of high production cost, low assembly efficiency and poor structural stability. Summary of the Utility Model

[0004] In view of the above problems, the utility model provides a water wheel for two-way water injection and an air conditioner having the same, which overcome or at least partially solve the above problems.

[0005] One object of the first aspect of the utility model is to simplify the water injection structure to realize low-cost two-way water injection.

[0006] A further object of the first aspect of the utility model is to further reduce the production cost of the water wheel.

[0007] Another further object of the first aspect of the utility model is to improve the water injection efficiency and water injection uniformity of the water wheel to optimize the heat dissipation effect.

[0008] The object of the second aspect of the utility model is to provide an air conditioner having the above water wheel.

[0009] According to the first aspect of the present utility model, the present utility model provides a water wheel, which is characterized in that the water wheel includes a wheel body and a rotating shaft arranged in the middle of the wheel body. The rotating shaft is used to be connected with an external driving mechanism to drive the wheel body to rotate; wherein

[0010] At least one first water injection hole and at least one second water injection hole are formed on the wheel body. The first water injection hole and the second water injection hole are configured to inject water outward from both sides of the wheel body in the axial direction of the rotating shaft respectively.

[0011] Further, the wheel body includes a first surface and a second surface arranged opposite to each other in the axial direction of the rotating shaft, and the water injection hole penetrates through the first surface and the second surface; wherein

[0012] The first annular wall surface formed inside the first water injection hole is arranged with a wider front and a narrower rear in the direction from the second surface to the first surface, so as to guide the coolant in the first water injection hole to flow towards the first surface; and

[0013] The second annular wall surface formed inside the second water injection hole is arranged with a wider front and a narrower rear in the direction from the first surface to the second surface, so as to guide the coolant in the second water injection hole to flow towards the second surface.

[0014] Further, the wheel body is made by a die casting process, and the draft direction of the first water injection hole and the draft direction of the second water injection hole are arranged opposite to each other in the axial direction of the rotating shaft.

[0015] Further, the annular wall surface has a windward surface and a leeward surface arranged along the rotation direction of the wheel body, and the included angle between the windward surface and the axial direction of the rotating shaft is smaller than the included angle between the leeward surface and the axial direction of the rotating shaft.

[0016] Further, a plurality of first water injection holes arranged at annular intervals and a plurality of second water injection holes arranged at annular intervals are formed on the wheel body.

[0017] Further, the number of the first water injection holes and the second water injection holes is the same, and the plurality of first water injection holes and the plurality of second water injection holes are arranged in a staggered manner one by one along the circumferential direction of the rotating shaft.

[0018] Further, the plurality of first water injection holes and the plurality of second water injection holes are evenly spaced along the circumferential direction of the rotating shaft.

[0019] Further, the water injection hole extends obliquely along the rotation direction of the wheel body and away from the rotating shaft.

[0020] Further, the projection of the water injection hole in the axial direction of the rotating shaft is in a crescent shape that is curved towards the rotation direction and is narrower inside and wider outside in the radial direction of the rotating shaft.

[0021] Further, the wheel body and the rotating shaft are of an integral structure.

[0022] According to a second aspect of the present utility model, the present utility model further provides an air conditioner, which includes:

[0023] A casing;

[0024] A heat exchanger disposed within the casing, and the heat exchanger includes a plurality of heat exchange fins;

[0025] A water tank disposed below the heat exchanger; and

[0026] The water wheel of any of the above solutions, the lower part of the water wheel is disposed within the water tank, and each water wheel is disposed between two adjacent heat exchange fins for pumping the coolant within the water tank towards two adjacent heat exchange fins.

[0027] The water wheel of the present utility model includes a wheel body and a rotating shaft disposed in the middle of the wheel body. The rotating shaft is used to be connected to an external driving mechanism to drive the wheel body to rotate. At least one first water pumping hole and at least one second water pumping hole are formed on the wheel body, and the first water pumping hole and the second water pumping hole are configured to pump water outwards from both sides of the wheel body in the axial direction of the rotating shaft respectively, so as to simultaneously bring water into two heat dissipation components located on both axial sides of the water wheel. By respectively forming the first water pumping hole and the second water pumping hole with opposite water pumping directions on the wheel body of the water wheel, the present utility model can achieve the dual-direction water pumping function of simultaneously bringing water into the heat dissipation components located on both axial sides of the water wheel, making the structure of the water wheel with the dual-direction water pumping function very simple, effectively reducing the manufacturing cost of the water wheel. At the same time, the water wheel is only provided with a wheel body and a connecting shaft, and the water pumping holes for realizing the dual-direction water pumping function are directly formed on the wheel body, without the need for connection and fixation between multiple components, improving the structural stability of the water wheel, reducing the possibility of failures caused by poor structural stability, and reducing the subsequent use cost. Thus, the water wheel of the present utility model simplifies the water pumping structure and realizes low-cost dual-direction water pumping.

[0028] Further, the wheel body in the water wheel of the present utility model includes a first surface and a second surface disposed away from each other in the axial direction of the rotating shaft. The water injection holes penetrate through the first surface and the second surface, reducing the manufacturing difficulty of the water injection holes, thereby reducing the production cost of the water wheel. In addition, in the water wheel of the present utility model, the first annular wall surface formed inside the first water injection hole is arranged with a wider front and a narrower rear in the direction from the second surface to the first surface to guide the coolant in the first water injection hole to flow towards the first surface. Thus, when the water wheel rotates, the coolant in the first water injection hole is guided to be thrown outwards from the first surface, and further, the water wheel realizes water injection outwards from the side where the first surface of the wheel body is located. At the same time, the second annular wall surface formed inside the second water injection hole is arranged with a wider front and a narrower rear in the direction from the first surface to the second surface to guide the coolant in the second water injection hole to flow towards the second surface. Thus, when the water wheel rotates, the coolant in the second water injection hole is guided to be thrown outwards from the second surface, and further, the water wheel realizes water injection outwards from the side where the second surface of the wheel body is located. Thereby, the water injection directions of the first water injection hole and the second water injection hole are opposite to each other in the axial direction of the rotating shaft, so that the water wheel can use the first water injection hole and the second water injection hole to inject water towards both axial sides respectively. That is to say, the water wheel of the present utility model can realize the two-way water injection function by only forming the first water injection hole and the second water injection hole through the wheel body, without complex assembly steps, improving the assembly efficiency, and further reducing the production cost of the water wheel.

[0029] Further, the water wheel of the present utility model is provided with a plurality of first water injection holes arranged at annular intervals and a plurality of second water injection holes arranged at annular intervals on the wheel body. Thus, when the water wheel rotates, the plurality of first water injection holes and the plurality of second water injection holes can respectively throw out multiple water streams outwards towards both sides of the wheel body in the axial direction of the rotating shaft to simultaneously inject water to multiple positions of the heat dissipation components located on both axial sides of the water wheel, thereby improving the water injection efficiency and water injection uniformity of the water wheel, and further optimizing the heat dissipation effect.

The same reference numerals in the drawings denote the same or similar components or parts. Those skilled in the art should understand that these drawings are not necessarily drawn to scale.

[0036] Figure 5 is Figure 2 Schematic diagram of the structure of the water wheel shown at another angle. Detailed implementation manners

[0037] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0038] The present invention first provides an air conditioner. Figure 1 is a schematic diagram of the structure of an air conditioner 1 according to an embodiment of the present invention. As Figure 1 shown, the air conditioner 1 of the present invention generally includes a housing 11, a heat exchanger 12, and a water spraying device 13.

[0039] As Figure 1 shown, the heat exchanger 12 is disposed in the housing 11, and the heat exchanger 12 includes a plurality of heat exchange fins 14. Specifically, the plurality of heat exchange fins 14 are spaced apart, and a gap 15 for heat dissipation is formed between two adjacent heat exchange fins 14.

[0040] In addition, as Figure 1 shown, the water spraying device 13 is disposed at the bottom position in the housing 11. The water spraying device 13 includes at least one water wheel 10, a water tank 20, and a driving mechanism 30. Specifically, the water tank 20 is disposed below the heat exchanger 12, and it has an open top and contains a coolant for heat dissipation. The lower part of the water wheel 10 is disposed in the water tank 20, and each water wheel 10 is disposed between two adjacent heat exchange fins 14 for spraying the coolant in the water tank 20 onto two adjacent heat exchange fins 14. That is to say, each water wheel 10 is disposed in the gap 15 formed between two adjacent heat exchange fins 14 adjacent to the water wheel 10. The driving mechanism 30 is used to drive the water wheel 10 to rotate, so as to drive the coolant in the water tank 20 to be thrown onto each heat exchange fin 14 adjacent to the water wheel 10.

[0041] Specifically, as Figure 1As shown, multiple heat exchange fins 14 are all vertically arranged, and the rotation axis of the water pumping wheel 10 is horizontally arranged. Thus, when the water pumping wheel 10 rotates, the coolant in the water tank 20 is driven by the water pumping wheel 10 and is tilted upward and to both sides and thrown out, respectively falling onto the heat exchange fins 14 located on both sides of the water pumping wheel 10, and dripping downward from the heat exchange fins 14 under the action of gravity, so as to take away the heat of the heat exchange fins 14 during the downward dripping process, thereby reducing the temperature of the heat exchange fins 14, and further playing a role in cooling and dissipating heat for the heat exchangers 12 located on both sides of the water pumping wheel 10, thereby effectively improving the heat dissipation efficiency of the heat exchangers 12, and further optimizing the heat dissipation effect. At the same time, one water pumping wheel 10 can take into account two groups of heat exchange fins 14 in the heat exchanger 12, improving the uniformity of heat dissipation of the heat exchanger 12, thereby further optimizing the heat dissipation effect, and further improving the overall performance of the air conditioner 1.

[0042] In some embodiments, as Figure 1 shown, the driving mechanism 30 may include a driving motor 31 and a driving shaft 32. The driving shaft 32 is in transmission connection with the output shaft of the driving motor 31 to rotate under the drive of the driving motor 31. The driving shaft 32 is also in transmission connection with the water pumping wheel 10 to drive the water pumping wheel 10 to rotate.

[0043] In a specific embodiment, the water pumping device 13 includes multiple water pumping wheels 10, and the multiple water pumping wheels 10 are arranged at intervals along the axial direction of the driving shaft 32. In this embodiment, the driving mechanism 30 can drive multiple water pumping wheels 10 simultaneously to make the multiple water pumping wheels 10 rotate synchronously. In an optional implementation manner, one end of the driving shaft 32 close to the driving motor 31 is in transmission connection with the output shaft of the driving motor 31, and the other end of the driving shaft 32 far from the driving motor 31 is simultaneously in transmission connection with multiple water pumping wheels 10 to drive the multiple water pumping wheels 10 to rotate synchronously. Thus, the driving mechanism 30 can drive multiple water pumping wheels 10 simultaneously and drive the multiple water pumping wheels 10 to rotate synchronously, so that the heat dissipation efficiencies of the multiple water pumping wheels 10 are consistent, thereby improving the heat dissipation uniformity of the heat exchanger 12.

[0044] In another optional implementation manner of the above specific embodiment, the driving mechanism 30 may further include a connecting shaft 33 arranged between every two adjacent water pumping wheels 10, and both ends of the connecting shaft 33 are in transmission connection with the two adjacent water pumping wheels 10 respectively. In this optional implementation manner, one end of the driving shaft 32 close to the driving motor 31 is in transmission connection with the output shaft of the driving motor 31, and the other end of the driving shaft 32 far from the driving motor 31 is only in transmission connection with one water pumping wheel 10 closest to the driving motor 31 among the multiple water pumping wheels 10. Thus, the driving mechanism 30 can directly drive one water pumping wheel 10 and drive other water pumping wheels 10 to rotate synchronously, improving the effectiveness of the transmission connection by using the connecting shaft 33, thereby improving the overall structural stability of the water pumping device 13 and further ensuring the heat dissipation efficiency of the water pumping device 13.

[0045] In a specific embodiment, the air conditioner 1 can be a mobile air conditioner. Specifically, as Figure 1 shown, the air conditioner 1 is provided with a plurality of casters 16 at the bottom of the housing 11 to facilitate the movement of the air conditioner 1. Of course, in other specific embodiments, the air conditioner 1 can also be other forms of air conditioners.

[0046] The present utility model also provides a water wheel 10. Figure 2 is Figure 1 a schematic structural view of the water wheel 10 of the air conditioner 1 shown. As Figure 2 shown, the water wheel 10 of the present utility model can include a wheel body 100 and a rotating shaft 200.

[0047] As Figure 2 shown, the rotating shaft 200 is arranged in the middle of the wheel body 100 and is used for driving connection with an external driving mechanism 30 to drive the wheel body 100 to rotate. Thus, the rotation axis of the water wheel 10 is the central axis of the rotating shaft 200. Specifically, the wheel body 100 is integrally in a disc shape, and the rotating shaft 200 is connected to the wheel body 100 in such a way that the axial direction is perpendicular to the plate surface of the wheel body 100, so as to drive the wheel body 100 to rotate around the central axis of the rotating shaft 200 under the drive of the external driving mechanism 30. In addition, as Figure 2 shown, at least one first water injection hole 300 and at least one second water injection hole 400 are formed in the wheel body 100. The first water injection hole 300 and the second water injection hole 400 are configured to inject water outward from both sides of the wheel body 100 in the axial direction of the rotating shaft 200 respectively.

[0048] The water wheel 10 in the embodiment of the present utility model includes a wheel body 100 and a rotating shaft 200 disposed in the middle of the wheel body 100. The rotating shaft 200 is used to connect with an external driving mechanism 30 to drive the wheel body 100 to rotate. At least one first water injection hole 300 and at least one second water injection hole 400 are formed on the wheel body 100. The first water injection hole 300 and the second water injection hole 400 are configured to inject water outward from both sides of the wheel body 100 in the axial direction of the rotating shaft 200, so as to simultaneously bring water into two heat dissipation components located on both axial sides of the water wheel 10. In the embodiment of the present utility model, by respectively forming the first water injection hole 300 and the second water injection hole 400 with opposite water injection directions on the wheel body 100 of the water wheel 10, the two-way water injection function of simultaneously bringing water into the heat dissipation components located on both axial sides of the water wheel 10 can be realized, so that the structure of the water wheel 10 with the two-way water injection function is very simple, effectively reducing the production cost of the water wheel 10. At the same time, the two-way water injection function can be realized only by opening holes on the wheel body 100 of a single water wheel 10, without complicated assembly steps, improving the assembly efficiency, and further reducing the production cost of the water wheel 10. In addition, the water wheel 10 is only provided with the wheel body 100 and the rotating shaft 200, and the water injection holes for realizing the two-way water injection function are directly formed on the wheel body 100, without the connection and fixation between multiple components, improving the structural stability of the water wheel 10, reducing the possibility of failures caused by poor structural stability, and reducing the subsequent use cost. Therefore, the water wheel 10 in the embodiment of the present utility model simplifies the water injection structure and realizes low-cost two-way water injection.

[0049] Figure 3 is Figure 2 The schematic cross-sectional view of the water wheel 10 shown in the figure taken along the line A-A. Figure 4 is Figure 2 The schematic structural view of the water wheel 10 shown in the figure taken along the line A-A. As Figure 3 shown, the wheel body 100 may include a first surface 110 and a second surface 120 disposed opposite to each other in the axial direction of the rotating shaft 200. As Figure 3 and Figure 4 shown, the water injection holes penetrate through the first surface 110 and the second surface 120, that is, both the first water injection hole 300 and the second water injection hole 400 are through holes penetrating through the first surface 110 and the second surface 120.

[0050] Specifically, as Figure 2 and Figure 3As shown, the first annular wall surface 310 formed inside the first water injection hole 300 is arranged with a wider front and a narrower rear in the direction from the second surface 120 to the first surface 110, so as to guide the water in the first water injection hole 300 to flow towards the first surface 110. Thus, when the water wheel 10 rotates, the water in the first water injection hole 300 is guided to be thrown outwards from the first surface 110, and further, the water wheel 10 realizes water injection outwards from the side where the first surface 110 of the wheel body 100 is located. In addition, the second annular wall surface 410 formed inside the second water injection hole 400 is arranged with a wider front and a narrower rear in the direction from the first surface 110 to the second surface 120, so as to guide the water in the second water injection hole 400 to flow towards the second surface 120. Thus, when the water wheel 10 rotates, the water in the second water injection hole 400 is guided to be thrown outwards from the second surface 120, and further, the water wheel 10 realizes water injection outwards from the side where the second surface 120 of the wheel body 100 is located.

[0051] In the water wheel 10 of the embodiment of the present utility model, the wheel body 100 includes a first surface 110 and a second surface 120 which are arranged away from each other in the axial direction of the rotating shaft 200, and the water injection holes penetrate through the first surface 110 and the second surface 120, reducing the manufacturing difficulty of the water injection holes, and thus reducing the production cost of the water wheel 10. In addition, in the water wheel 10 of the embodiment of the present utility model, the first annular wall surface 310 formed inside the first water injection hole 300 is arranged with a wider front and a narrower rear in the direction from the second surface 120 to the first surface 110, so as to guide the water in the first water injection hole 300 to flow towards the first surface 110. At the same time, the second annular wall surface 410 formed inside the second water injection hole 400 is arranged with a wider front and a narrower rear in the direction from the first surface 110 to the second surface 120, so as to guide the water in the second water injection hole 400 to flow towards the second surface 120. Thus, the water injection directions of the first water injection hole 300 and the second water injection hole 400 are opposite to each other in the axial direction of the rotating shaft 200, so that the water wheel 10 can use the first water injection hole 300 and the second water injection hole to inject water towards both axial sides respectively. That is to say, the water wheel 10 of the embodiment of the present utility model can realize the two-way water injection function only by forming the first water injection hole 300 and the second water injection hole 400 through the wheel body 100, without complicated assembly steps, improving the assembly efficiency, and thus further reducing the production cost of the water wheel 10.

[0052] In some embodiments, such as Figures 2 to 4As shown, the wheel body 100 can be made by a die forming process, and the draft directions of the first water injection holes 300 and the second water injection holes 400 are arranged to be opposite in the axial direction of the rotating shaft 200. Specifically, the wheel body 100 can be a plastic part made by an injection molding process. The draft directions of the first water injection holes 300 and the second water injection holes 400 are opposite, so that the first annular wall surface 310 in the first water injection holes 300 and the second annular wall surface 410 in the second water injection holes 400 are respectively arranged with a wider front and a narrower rear along opposite directions to form the structure of the wheel body 100.

[0053] In the water wheel 10 of the embodiment of the present invention, by forming the first water injection holes 300 and the second water injection holes 400 on the wheel body 100 only in opposite draft directions respectively, the bidirectional water injection function of the water wheel 10 can be realized, without complex assembly steps, improving the assembly efficiency, and thus further reducing the production cost of the water wheel 10.

[0054] Furthermore, as Figures 2 to 4 shown, the wheel body 100 and the rotating shaft 200 can be an integral structure. Specifically, the water wheel 10 can be an integral plastic part made by an injection molding process. Thus, a stable connection relationship is formed between the wheel body 100 and the rotating shaft 200, improving the structural stability of the water wheel 10.

[0055] In some embodiments, the annular wall surface has a windward surface and a leeward surface arranged along the rotation direction C of the wheel body 100. Specifically, as Figure 2 and Figure 4 shown, the windward surface includes a first windward surface 311 on the first annular wall surface 310 and a second windward surface 411 on the second annular wall surface 410, and the leeward surface includes a first leeward surface 312 on the first annular wall surface 310 and a second leeward surface 412 on the second annular wall surface 410. In this embodiment, as Figure 4 shown, the included angle between the windward surface and the axial direction of the rotating shaft 200 is smaller than the included angle between the leeward surface and the axial direction of the rotating shaft 200. That is to say, the inclination degree of the leeward surface in the axial direction of the rotating shaft 200 is greater than the inclination degree of the windward surface in the axial direction of the rotating shaft 200. Thus, when the wheel body 100 rotates along its rotation direction C, the flow rate of the coolant on the leeward surface flowing outwards is faster than that of the coolant on the windward surface flowing outwards.

[0056] It should be noted that the water scooping wheel 10 of the embodiment of the present utility model can use the duration of one rotation cycle for a water scooping hole to complete the rotation operation of starting from being completely immersed in the coolant in the water tank 20, rising above the water surface in the water tank 20 and continuing to rotate upward, reaching the highest position, continuing to rotate downward from the highest position, and until being immersed in the water tank 20 again. In the first half of a rotation cycle, under the action of rotational inertia, the rotation operation of the water scooping hole from the coolant in the water tank 20 to rising above the water surface in the water tank 20 and continuing to rotate upward until reaching the highest position will drive the coolant received in the water scooping hole to be thrown out obliquely upward and outward along the annular wall surface inside the water scooping hole. In the second half of a rotation cycle, under the action of rotational inertia, the rotation operation of the water scooping hole from the highest position and continuing to rotate downward until being immersed in the water tank 20 again will drive the remaining coolant in the water scooping hole to be thrown out obliquely downward and outward along the annular wall surface inside the water scooping hole. Since the water scooping wheel 10 is located below the heat exchange fins 14, and the working principle of the water scooping wheel 10 is to drive the coolant to be thrown upward until it falls onto the heat exchange fins 14 on both sides during rotation to cool and dissipate heat from the heat exchanger 12, the first half of a rotation cycle is the main working period in a rotation cycle.

[0057] In the first half of a rotation cycle, after the water scooping hole reaches a position above the water surface in the water tank 20, the windward surface is located below the leeward surface. At this time, the angle between the windward surface and the axial direction of the rotating shaft 200 is relatively small, which can enable the windward surface to receive and store more coolant. As the wheel body 100 continues to rotate, the position of the water scooping hole gradually rises, and the coolant received and stored on the windward surface gradually flows toward the leeward surface. At this time, the angle between the leeward surface and the axial direction of the rotating shaft 200 is relatively large, which can increase the speed of the leeward surface throwing out the coolant outward.

[0058] Therefore, for the water scooping wheel 10 of the embodiment of the present utility model, by setting the windward surface and the leeward surface such that the angle between the windward surface and the axial direction of the rotating shaft 200 is smaller than the angle between the leeward surface and the axial direction of the rotating shaft 200, it can make the ability of the windward surface to receive and store coolant stronger than that of the leeward surface, and at the same time make the speed of the coolant flowing outward on the leeward surface faster than that on the windward surface, which is beneficial to quickly throwing out as much coolant as possible obliquely upward in the first half of a rotation cycle, thereby improving the water scooping efficiency of the water scooping wheel 10 in a single rotation cycle, and further optimizing the heat dissipation effect.

[0059] Figure 5 is Figure 2 The structural schematic diagram of the water scooping wheel 10 shown in another angle. In this embodiment, the water scooping hole extends obliquely along the rotation direction C of the wheel body 100 and away from the rotating shaft 200. Specifically, as Figure 2 andFigure 5 As shown, both the first water injection holes 300 and the second water injection holes 400 extend obliquely along the rotation direction C of the wheel body 100 and away from the rotating shaft 200.

[0060] Thus, the first water injection holes 300 and the second water injection holes 400 are arranged to extend obliquely, optimizing the internal water flow path. The obliquely extending water injection holes can better guide the coolant to flow along the rotation direction C of the wheel body 100 and away from the rotating shaft 200, reducing the resistance of the coolant during the flow process. Therefore, it helps to send the coolant received and stored inside the water injection holes to a higher position during the upward rotation of the wheel body 100 when the wheel body 100 rotates, thereby improving the water injection efficiency of the water injection wheel 10 and further optimizing the heat dissipation effect.

[0061] Furthermore, as Figure 3 shown, the wheel body 100 is in the shape of a disc with a thick center and thin edges. Thus, the water injection holes are arranged to gradually narrow from the inside to the outside in the extending direction from the center to the edge of the wheel body 100, thereby reducing the escape resistance of the coolant when it flows to the position near the edge of the wheel body 100 inside the water injection holes. Therefore, it helps to quickly eject the coolant received and stored inside the water injection holes when the wheel body 100 rotates, thereby improving the water injection efficiency of the water injection wheel 10 and further optimizing the heat dissipation effect.

[0062] In some embodiments, as Figure 2 and Figure 5 shown, the projection of the water injection holes in the axial direction of the rotating shaft 200 is in the shape of a crescent that bends towards the rotation direction C and is narrow inside and wide outside in the radial direction of the rotating shaft 200, thereby increasing the water throwing area at one end of the water injection holes near the edge of the wheel body 100. Thus, during the rotation of the wheel body 100, after the coolant received and stored inside the water injection holes quickly swings from one end of the water injection holes near the center of the wheel body 100 to one end of the water injection holes near the edge of the wheel body 100, it can be thrown out in a larger range from one end of the water injection holes near the edge of the wheel body 100, thereby improving the water injection uniformity of the water injection wheel 10 and further optimizing the heat dissipation effect.

[0063] In some embodiments, as Figure 2 and Figure 5 shown, a plurality of first water injection holes 300 arranged at annular intervals and a plurality of second water injection holes 400 arranged at annular intervals are provided on the wheel body 100.

[0064] Thus, when the water injection wheel 10 rotates, the plurality of first water injection holes 300 and the plurality of second water injection holes 400 can respectively eject multiple beams of water outward from both sides of the wheel body 100 in the axial direction of the rotating shaft 200 to simultaneously hit multiple positions of the components to be heat-dissipated located on both axial sides of the water injection wheel 10, thereby improving the water injection efficiency and water injection uniformity of the water injection wheel 10, and further optimizing the heat dissipation effect.

[0065] In some embodiments, such as Figure 2 and Figure 5 shown, the number of the first water injection holes 300 and the second water injection holes 400 is the same, and the plurality of first water injection holes 300 and the plurality of second water injection holes 400 are arranged alternately along the circumferential direction of the rotating shaft 200. Specifically, the wheel body 100 can be made by a die forming process, and the draft directions of the water injection holes on the wheel body 100 are alternately arranged in opposite directions, so as to form a two-way water injection structure that injects water to both axial sides of the wheel body 100 simultaneously.

[0066] In the water wheel 10 of the embodiment of the present utility model, by respectively forming a plurality of first water injection holes 300 and a plurality of second water injection holes 400 with the same number and arranged alternately in opposite draft directions only on the wheel body 100, it is ensured that the water injection amounts of the water wheel 10 injecting water to both axial sides are basically the same, thereby improving the water injection uniformity of the water wheel 10 injecting water to both axial sides, and further optimizing the heat dissipation effect.

[0067] In some embodiments, such as Figure 5 shown, the plurality of first water injection holes 300 and the plurality of second water injection holes 400 are evenly spaced along the circumferential direction of the rotating shaft 200, ensuring that the same number of water injection holes are above the water surface in the water tank 20 at each time point within a rotation period of the water wheel 10, thereby ensuring that the water injection amounts of the water wheel 10 at each time period within a rotation period are basically the same, further improving the water injection uniformity of the water wheel 10, and further optimizing the heat dissipation effect.

[0068] Those skilled in the art should also understand that the terms such as "upper", "lower", "front", "rear", "bottom", "inner", "outer", etc., used to represent the orientation or position relationship in the embodiments of the present utility model are based on the actual use states of the water wheel 10 and the air conditioner 1. These terms are only for the convenience of describing and understanding the technical solution of the present utility model, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0069] So far, those skilled in the art should recognize that although a plurality of exemplary embodiments of the present utility model have been shown and described in detail herein, still, without departing from the spirit and scope of the present utility model, many other variations or modifications that conform to the principles of the present utility model can be directly determined or derived based on the content disclosed in the present utility model.
