Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and more specifically, to an air conditioner. Background Technology

[0002] With the development of the times, big data has gradually permeated our lives, and the increasing amount of data computing has led to an increase in the operating frequency of servers, which in turn increases the heat dissipation required by the servers themselves. Therefore, in-row air conditioning, as a product specifically designed for servers, has increasingly come into focus. Compared to traditional air conditioners, in-row air conditioning offers a clearer and more direct solution to the problem of localized heat dissipation in servers. Consequently, more and more data centers are increasingly favoring in-row air conditioning to control the temperature of server racks. Traditional in-row air conditioners rely on bolts to secure the fan brackets to a baffle plate. During operation, air enters the unit through the rear door, passes through a coarse filter and evaporator, and is then carried out by the rotating fan blades, directed towards the front of the unit.

[0003] However, with the increasing demand for in-row air conditioning, the limitations of traditional in-row air conditioning systems have gradually become apparent. Because most traditional in-row air conditioners have front and rear air intakes and exhausts, and are limited by the width of the unit, the area and direction of the air intake and exhaust are greatly restricted. This results in poor airflow flexibility and a single airflow direction, which in turn greatly limits the cooling capacity and utilization rate of the fan, leading to lower cooling capacity and efficiency. Summary of the Invention

[0004] The main objective of this invention is to provide an air conditioner that solves the problem of poor airflow flexibility in the inter-row air conditioning system of the prior art.

[0005] To achieve the above objectives, the present invention provides an air conditioner, including a housing and multiple fan assemblies, the multiple fan assemblies being spaced apart on the housing; the housing having an air inlet; each fan assembly including a fan and a drive mechanism, the fan having a fan inlet and a fan outlet, so that air passes through the air inlet and the fan inlet in sequence and is discharged from the fan outlet; the drive mechanism is driven and connected to the fan, so that the drive mechanism drives the fan to rotate, thereby changing the air outlet direction of the fan.

[0006] Furthermore, the drive mechanism includes: a first drive assembly connected to the fan drive to drive the fan to rotate around a first rotation axis; and a second drive assembly connected to the fan drive to drive the fan to rotate around a second rotation axis; wherein the first rotation axis extends along the radial direction of the fan, and the second rotation axis extends along the axial direction of the fan.

[0008] Furthermore, the first connecting bracket includes a second connecting plate, a third side plate, and a fourth side plate. The third and fourth side plates are both connected to the second connecting plate and located on opposite sides of the second connecting plate. The second connecting plate and the fan are sequentially arranged along the axial direction of the fan, and the third and fourth side plates are located on opposite sides of the fan. The second drive assembly is drivenly connected to the second connecting plate. The first drive assembly includes a first drive member and a second drive member. The first drive member is disposed on the third side plate, and its output end is drivenly connected to the fan. The second drive member is disposed on the fourth side plate, and its output end is drivenly connected to the fan. The output ends of both the first and second drive members are rotatably disposed, and the axes of the output ends of both the first and second drive members coincide with the first rotation axis.

[0009] Furthermore, the first connecting bracket is provided with a first connecting hole, and the second connecting bracket is provided with a second connecting hole that communicates with the first connecting hole; each fan assembly also includes: a flexible tube made of flexible material, the first end of the flexible tube being connected to the first connecting bracket, and the second end of the flexible tube being connected to the fan, so that the air entering through the second connecting hole and the first connecting hole passes through the flexible tube and then enters the fan through the fan inlet.

[0010] Furthermore, the fan outlet is located on the circumferential side wall of the fan; each fan component also includes: a fan bracket, which is fixedly connected to the fan; and an air guide plate, which is fixedly connected to the fan bracket and extends along the circumference of the fan. The air guide plate is opposite to and spaced apart from the fan outlet to form an air guide channel connected to the fan outlet and an air outlet connected to the air guide channel. The air outlet is used to deliver air towards the front of the air conditioner.

[0011] Furthermore, each fan assembly includes at least two air guide plates, which are arranged sequentially along the circumferential direction of the fan; the at least two air guide plates include a first air guide plate and a second air guide plate; the first air guide plate has a first end and a second end arranged sequentially along the circumferential direction of the fan, and the first end and the second end of the first air guide plate are respectively fixedly connected to both ends of the fan support; the second air guide plate is arranged on opposite sides of the first air guide plate, and the second air guide plate has a first end and a second end arranged sequentially along the circumferential direction of the fan, and the first end and the second end of the second air guide plate are respectively connected to both ends of the fan support.

[0012] Furthermore, the fan support includes a first connecting plate, a first side plate, and a second side plate. Both the first and second side plates are connected to the first connecting plate and are located on opposite sides of the first connecting plate.

[0014] Furthermore, the air conditioner also includes: a controller, which is communicatively connected to multiple fan assemblies; and a temperature sensor, which is installed at the location to be cooled. The temperature sensor is communicatively connected to the controller so that when the temperature sensor detects that the temperature at the location to be cooled is higher than a preset temperature, the controller controls a first drive assembly of at least one fan assembly to drive the fan to rotate around a first rotation axis by a first preset angle, and controls a second drive assembly of at least one fan assembly to drive the fan to rotate around a second rotation axis by a second preset angle, so that the fan outlet of the fan of at least one fan assembly is oriented toward the location to be cooled.

[0015] The air conditioner using the technical solution of this invention includes a housing and multiple fan assemblies. The housing has an air inlet, and each fan assembly includes a fan and a drive mechanism. The fan has a fan inlet and a fan outlet. Air passes through the air inlet and fan outlet sequentially and is discharged from the fan outlet. The drive mechanism drives the fan to rotate, changing the air outlet direction and avoiding a single air outlet direction. Furthermore, since each fan assembly works independently and each fan is driven by a corresponding drive mechanism, the air outlet direction of each fan is different, enabling multiple air outlets from a single air conditioner and increasing the air outlet area of ​​the fan. This solves the problem of poor air outlet flexibility in existing inter-row air conditioners, improves the cooling efficiency of the air conditioner, and shortens the time required to adjust to ambient temperature. In addition, the adjustable air outlet direction of each fan allows for targeted cooling of high-temperature areas, reducing resource waste. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] This invention provides an air conditioner; please refer to [the relevant documentation]. Figures 1 to 6 The device includes a housing 10 and multiple fan assemblies 20, which are spaced apart on the housing 10. The housing 10 has an air inlet. Each fan assembly 20 includes a fan 21 and a drive mechanism 22. The fan 21 has a fan inlet and a fan outlet 211, so that air passes through the air inlet and the fan outlet in sequence and is discharged from the fan outlet 211. The drive mechanism 22 is driven by the fan 21, so that the drive mechanism 22 drives the fan 21 to rotate, thereby changing the air outlet direction of the fan outlet 211.

[0030] The air conditioner of the present invention includes a housing 10 and multiple fan assemblies 20. The housing 10 has an air inlet, and each fan assembly 20 includes a fan 21 and a drive mechanism 22. The fan 21 has a fan inlet and a fan outlet 211. Air passes through the air inlet and the fan outlet in sequence and is discharged from the fan outlet 211. The drive mechanism 22 drives the fan 21 to rotate and change the air outlet direction of the fan outlet 211, which can avoid the fan 21 having a single air outlet direction. In addition, since each fan assembly 20 works independently and each fan 21 is driven by a corresponding drive mechanism 22, the air outlet direction of each fan 21 is different, which can realize multiple air outlets from one air conditioner and increase the air outlet area of ​​the fan 21. This solves the problem of poor air outlet flexibility of the existing inter-row air conditioner, improves the cooling efficiency of the air conditioner, and shortens the adjustment time for ambient temperature. In addition, the adjustable air outlet direction of each fan 21 can also target the cooling of high-temperature areas and reduce resource waste.

[0031] In this embodiment, the drive mechanism 22 includes: a first drive assembly 221, which is driven to connect to the fan 21 to drive the fan 21 to rotate around a first rotation axis 223; and a second drive assembly 222, which is driven to connect to the fan 21 to drive the fan 21 to rotate around a second rotation axis 224; wherein the first rotation axis 223 extends along the radial direction of the fan 21, and the second rotation axis 224 extends along the axial direction of the fan 21.

[0032] Specifically, such as Figure 4As shown, the first drive assembly 221 drives the fan 21 to rotate around the first rotation axis 223, and the second drive assembly 222 drives the fan 21 to rotate around the second rotation axis 224, thereby increasing the rotation range of the fan 21 and ensuring that the fan outlet 211 has multiple air outlet directions, thus expanding the area that the fan 21 can cover.

[0033] Optionally, the first rotation axis 223 and the second rotation axis 224 are arranged perpendicularly to each other.

[0034] In this embodiment, each fan assembly 20 further includes: a first connecting bracket 23, on which a first driving assembly 221 is disposed; a second connecting bracket 24, fixedly connected to the housing 10, on which a second driving assembly 222 is disposed, and the second driving assembly 222 is driven to the fan 21 through the first connecting bracket 23, so that the second driving assembly 222 drives the first connecting bracket 23 to rotate synchronously with the fan 21.

[0035] Specifically, the first connecting bracket 23 is used to connect the second driving component 222 and the fan 21. The second driving component 222 drives the first connecting bracket 23 to rotate synchronously with the fan 21, so that the fan 21 can rotate around the second rotation axis 224. The first driving component 221 drives the fan 21 to rotate around the first rotation axis 223, thereby increasing the rotation range of the fan 21 and ensuring that the fan outlet 211 has multiple air outlet directions, thereby expanding the area that the fan 21 can cover.

[0036] Optionally, the second connecting bracket 24 is fixedly connected to the housing 10 by bolts.

[0037] In this embodiment, the first connecting bracket 23 includes a second connecting plate 231, a third side plate 232, and a fourth side plate 233. The third side plate 232 and the fourth side plate 233 are both connected to the second connecting plate 231 and located on opposite sides of the second connecting plate 231. The second connecting plate 231 and the fan 21 are sequentially arranged along the axial direction of the fan 21, and the third side plate 232 and the fourth side plate 233 are located on opposite sides of the fan 21. The second driving assembly 222 is drivenly connected to the second connecting plate 231. The first driving assembly 221 includes a first driving member 2. 211 and 2212 are provided. The first drive member 2211 is disposed on the third side plate 232 and its output end is driven and connected to the fan 21. The second drive member 2212 is disposed on the fourth side plate 233 and its output end is driven and connected to the fan 21. The output ends of the first drive member 2211 and the second drive member 2212 are rotatably disposed. The axis of the output end of the first drive member 2211 and the axis of the output end of the second drive member 2212 are both coincident with the first rotation axis.

[0038] Specifically, the second connecting plate 231 is used to connect the second drive assembly 222 and the first connecting bracket 23, so that the second drive assembly 222 can drive the first connecting bracket 23 to rotate synchronously with the fan 21; the third side plate 232 is used to connect the first drive member 2211 and the first connecting bracket 23, and the fourth side plate 233 is used to connect the second drive member 2212 and the first connecting bracket 23. The first drive member 2211 and the second drive member 2212 jointly drive the fan 21 to rotate around the first rotation axis 223, thereby ensuring that the fan outlet 211 has multiple air outlet directions, thereby expanding the area that the fan 21 can cover.

[0039] In this embodiment, the first connecting bracket 23 is provided with a first connecting hole 235, and the second connecting bracket 24 is provided with a second connecting hole 236 that communicates with the first connecting hole 235; each fan assembly 20 further includes: a flexible tube 25 made of flexible material, the first end of the flexible tube 25 is connected to the first connecting bracket 23, and the second end of the flexible tube 25 is connected to the fan 21, so that the air entering through the second connecting hole 236 and the first connecting hole 235 passes through the flexible tube 25 and enters the fan 21 through the fan inlet.

[0040] Specifically, the flexible tube 25 is used to connect the first connecting bracket 23 and the fan 21, ensuring the airtightness of the fan assembly 20 and preventing air leakage. Air flows sequentially through the second connecting hole 236, the first connecting hole 235, the flexible tube 25, and the fan inlet into the fan 21. The flexible tube 25 is made of a flexible material, allowing it to deform accordingly as the fan 21 rotates around the first rotation axis 223. This prevents the flexible tube 25 from restricting the rotation range of the fan 21, further ensuring that the fan outlet 211 has multiple airflow directions and expanding the coverage area of ​​the fan 21's airflow.

[0041] Specifically, the length of the flexible tube 25 must be greater than the distance between the fan 21 and the first connecting bracket 23, and the length must be sufficient to allow the fan 21 to be normally connected between the fan 21 and the first connecting bracket 23 when the fan 21 is rotating at its maximum angle, without the flexible tube 25 breaking or being damaged.

[0042] In this embodiment, the fan outlet 211 is disposed on the circumferential sidewall of the fan 21; each fan assembly 20 further includes: a fan bracket 26, which is fixedly connected to the fan 21; and an air guide plate 27, which is fixedly connected to the fan bracket 26 and extends along the circumference of the fan 21. The air guide plate 27 is opposite to and spaced apart from the fan outlet 211 to form an air guide channel 28 connected to the fan outlet 211 and an air outlet 29 connected to the air guide channel 28. The air outlet 29 is used to deliver air towards the front of the air conditioner.

[0043] Specifically, the fan bracket 26 is used to install the fan 21, and the air guide plate 27 is set to restrict the direction of air flow, so that the air flowing out from the fan outlet 211 flows through the air guide channel 28 and flows out from the air outlet 29, thereby causing the air to flow towards the front of the air conditioner, preventing the air flowing out from the fan outlet 211 from escaping to the surroundings, thereby improving the cooling efficiency of the air conditioner.

[0044] Specifically, the front of the air conditioner refers to the space on the side of the fan 21 away from the second connecting bracket 24 along the axial direction of the fan 21.

[0045] In this embodiment, each fan assembly 20 includes at least two air guide plates 27, which are arranged sequentially along the circumferential direction of the fan 21. The at least two air guide plates 27 include a first air guide plate 271 and a second air guide plate 272. The first air guide plate 271 has a first end and a second end arranged sequentially along the circumferential direction of the fan 21, and the first end and the second end of the first air guide plate 271 are respectively fixedly connected to the two ends of the fan bracket 26. The second air guide plate 272 and the first air guide plate 271 are arranged on opposite sides of the fan bracket 26, and the second air guide plate 272 has a first end and a second end arranged sequentially along the circumferential direction of the fan 21, and the first end and the second end of the second air guide plate 272 are respectively connected to the two ends of the fan bracket 26.

[0046] Specifically, the first and second ends of the first air guide plate 271 are fixedly connected to the two ends of the fan bracket 26, so that the first air guide plate 271 is opposite to and spaced apart from the fan outlet 211 to form an air guide channel 28 connected to the fan outlet 211 and an air outlet 29 connected to the air guide channel 28; the first and second ends of the second air guide plate 272 are connected to the two ends of the fan bracket 26, so that the second air guide plate 272 is opposite to and spaced apart from the fan outlet 211 to form an air guide channel 28 connected to the fan outlet 211 and an air outlet 29 connected to the air guide channel 28. The first air guide plate 271 and the second air guide plate 272 set on opposite sides of the fan bracket 26 ensure that the air flowing out of the fan outlet 211 flows through the air guide channel 28 and flows out of the air outlet 29, thereby causing the air to flow towards the front of the air conditioner, ensuring both the direction of air flow and the air volume flowing towards the front of the air conditioner.

[0047] Optionally, the first end and the second end of the first air guide plate 271 are fixedly connected to the two ends of the fan bracket 26 by self-tapping screws; the first end and the second end of the second air guide plate 272 are connected to the two ends of the fan bracket 26 by self-tapping screws.

[0048] In this embodiment, the fan bracket 26 includes a first connecting plate 261, a first side plate 262, and a second side plate 263. The first side plate 262 and the second side plate 263 are both connected to the first connecting plate 261 and are located on opposite sides of the first connecting plate 261. The first connecting plate 261 is fixedly connected to the fan 21 and is arranged sequentially with the fan 21 along the axial direction of the fan 21. The first side plate 262 and the second side plate 263 are located on opposite sides of the fan 21. The first end of the first air guide plate 271 is connected to the first side plate 262, and the second end of the first air guide plate 271 is connected to the second side plate 263. The first end of the second air guide plate 272 is connected to the first side plate 262, and the second end of the second air guide plate 272 is connected to the second side plate 263.

[0049] Specifically, the first connecting plate 261 is used to connect the fan 21 and the fan bracket 26, and the first side plate 262 and the second side plate 263 are used to connect the air guide plate 27 and the fan bracket 26. The first side plate 262 and the second side plate 263 are also used to limit the fan 21 to prevent the fan 21 from moving in its radial direction.

[0050] In this embodiment, the air guide plate 27 is an arc-shaped plate that extends along the circumferential direction of the fan 21.

[0051] Specifically, the air guide plate 27 is an arc-shaped plate that extends along the circumferential direction of the fan 21, so that the shape of the air guide plate 27 matches the shape of the fan 21. This ensures that the formed air guide channel 28 can be connected to more fan outlets 211, further ensuring that the air flowing out of the fan outlet 211 flows through the air guide channel 28 and out of the air outlet 29, thereby causing the air to flow towards the front of the air conditioner and improving the cooling efficiency of the air conditioner.

[0052] In this embodiment, the air conditioner further includes: a controller, which is communicatively connected to multiple fan assemblies 20; and a temperature sensor, which is installed at the location to be cooled. The temperature sensor is communicatively connected to the controller so that when the temperature sensor detects that the temperature at the location to be cooled is higher than a preset temperature, the controller controls the first drive assembly 221 of at least one fan assembly 20 to drive the fan 21 to rotate around the first rotation axis 223 by a first preset angle, and the controller controls the second drive assembly 222 of at least one fan assembly 20 to drive the fan 21 to rotate around the second rotation axis 224 by a second preset angle, so that the fan outlet 211 of the fan 21 of at least one fan assembly 20 is oriented toward the location to be cooled.

[0053] Specifically, when the temperature sensor detects that the temperature of the location to be cooled is higher than the preset temperature, it transmits a signal to the controller. The controller controls the first drive component 221 of at least one fan assembly 20 to drive the fan 21 to rotate around the first rotation axis 223 by a first preset angle, and controls the second drive component 222 of at least one fan assembly 20 to drive the fan 21 to rotate around the second rotation axis 224 by a second preset angle. This causes the fan outlet 211 of the fan 21 of at least one fan assembly 20 to be oriented towards the location to be cooled, so that the air outlet 29 of at least one fan 21 blows air towards the location to be cooled, thereby achieving precise and rapid cooling of the location to be cooled, and thus improving the cooling efficiency of the air conditioner.

[0054] In specific implementation, such as Figure 7 As shown, the air conditioner starts, the temperature is set, and the customer selects between automatic and manual control modes according to their needs. When manual control mode is selected, the number of fans 21 whose rotation direction needs adjustment is determined by setting the cooling position. Then, the horizontal and vertical coordinates of each fan 21 are set (i.e., the first preset angle of rotation of the fan 21 around the first rotation axis 223 and the second preset angle of rotation of the fan 21 around the second rotation axis 224 are determined). After data confirmation, the controller controls the first drive assembly 221 and the second drive assembly 222 to rotate, adjusting the orientation of the fans 21, and finally starts the fans to operate. When automatic control mode is selected, temperature sensors need to be installed at the cooling positions. Temperature sensors can be installed at multiple cooling positions as needed. Furthermore, according to the requirements, a corresponding number of temperature sensors are activated to cool multiple locations to be cooled. The controller is connected to the temperature sensors. When the temperature sensors detect that the temperature of the location to be cooled is higher than the preset temperature, they transmit a signal to the controller. The controller controls the first drive component 221 of at least one fan assembly 20 to drive the fan 21 to rotate around the first rotation axis 223 by a first preset angle, and the controller also controls the second drive component 222 of at least one fan assembly 20 to drive the fan 21 to rotate around the second rotation axis 224 by a second preset angle, so that the fan outlet 211 of the fan 21 of at least one fan assembly 20 is set towards the location to be cooled, and then the fan 21 is started.

[0055] In practice, when the fan 21 starts to run, the air flows through the coarse filter 1 to the evaporator 2. When passing through the evaporator 2, the air is cooled by the heat absorption of the refrigerant. Then it passes through the baffle 3 of the casing 10 and is finally sent out by the rotation of the fan 21.

[0056] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0057] This invention optimizes the installation method of the air conditioner's fan assembly 20, changing the original fixed front air outlet method to a more flexible rotatable air outlet method. By changing the air outlet direction of the fan outlet 211, it breaks through the limitations of the traditional air outlet direction of in-row air conditioners. By enabling air to be discharged from one air conditioner in multiple directions, it improves the local temperature control of multiple heat dissipation points. It improves the air conditioner's performance without changing its appearance. Through the reasonable use of the flexible tube 25, it ensures the airtightness of the fan assembly 20 and better guides the direction of air discharge.

[0058] The air conditioner of the present invention includes a housing 10 and multiple fan assemblies 20. The housing 10 has an air inlet, and each fan assembly 20 includes a fan 21 and a drive mechanism 22. The fan 21 has a fan inlet and a fan outlet 211. Air passes through the air inlet and the fan outlet in sequence and is discharged from the fan outlet 211. The drive mechanism 22 drives the fan 21 to rotate and change the air outlet direction of the fan outlet 211, which can avoid the fan 21 having a single air outlet direction. In addition, since each fan assembly 20 works independently and each fan 21 is driven by a corresponding drive mechanism 22, the air outlet direction of each fan 21 is different, which can realize multiple air outlets from one air conditioner and increase the air outlet area of ​​the fan 21. This solves the problem of poor air outlet flexibility of the existing inter-row air conditioner, improves the cooling efficiency of the air conditioner, and shortens the adjustment time for ambient temperature. In addition, the adjustable air outlet direction of each fan 21 can also target the cooling of high-temperature areas and reduce resource waste.
