[0001] This invention relates to the field of air conditioner technology, and in particular to a cabinet air conditioner and its control method. Background Technology

[0002] Currently, with the popularization of 5G base station air conditioners, integrated cabinet air conditioners are being used on a large scale as an important means of heat dissipation. An integrated cabinet combines relatively independent internal and external heat exchangers and installs them on the cabinet door to provide heat dissipation for the cabinet.

[0003] However, the unit is not easy to manufacture and maintain, and it only has a cooling function. When the ambient temperature is low, it cannot effectively use the ambient temperature to cool it down, which causes a certain degree of energy waste. Summary of the Invention

[0004] The purpose of this invention is to provide a cabinet air conditioner and its control method, which aims to solve the technical problem that existing cabinet air conditioners cannot effectively utilize ambient temperature for cooling.

The first partition and the second partition divide the internal space of the housing into an inner heat exchange area and an outer heat exchange area. The inner heat exchange area communicates with the interior of the rack, and the outer heat exchange area communicates with the exterior of the rack. An internal fan is disposed on one side of the second partition within the inner heat exchange area. When switching from a cooling mode to a fan-cooled mode, the drive assembly can drive the second partition to move upwards, and the internal fan can draw air from the outer heat exchange area to the inner heat exchange area.

[0006] In some embodiments, the external heat exchange area is provided with a condenser;

[0007] The condenser is disposed on the second partition; or, the condenser and the second partition are an integral structure.

[0008] When switching from cooling mode to air-cooling mode, the drive component can drive the condenser to move upward, so that the second partition moves upward.

[0009] In some embodiments, the cabinet air conditioner further includes a liquid cooling system, which includes a liquid cooling heat exchanger disposed on the condenser and located below the second partition. When switching from cooling mode to liquid cooling mode, the drive assembly drives the condenser to move upward and the liquid cooling heat exchanger to a position opposite to the internal fan.

[0015] In some embodiments, the external heat exchange area is further provided with an external fan and at least two third tracks extending in the horizontal direction, and the external fan is provided with third insert tracks that are inserted one-to-one with the at least two third tracks.

[0016] In some embodiments, the housing has a second opening for inserting the external fan, and the second opening is detachably provided with a second cover plate.

[0027] Where t0 is greater than t2.

[0028] Compared with the prior art, the cabinet air conditioner of the present invention has at least the following beneficial effects:

[0029] This invention discloses a rack-mounted air conditioner, which includes a housing and a drive assembly. The housing contains a first partition and a second partition, with the second partition positioned above the first partition. The first and second partitions divide the internal space of the housing into an inner heat exchange area and an outer heat exchange area. The inner heat exchange area communicates with the interior of the rack, and the outer heat exchange area communicates with the exterior of the rack. An internal fan is located on one side of the second partition in the inner heat exchange area. The rack-mounted air conditioner of this invention has a cooling mode and a fan-cooled mode. When switching from cooling mode to fan-cooled mode, the drive assembly drives the second partition to move upwards. After the second partition moves upwards, in… A channel connecting the external and internal heat exchange areas is formed between the lower part of the second partition and the top of the first partition. In this mode, the internal fan can draw air from the external heat exchange area to the internal heat exchange area. Since the external heat exchange area is connected to the outside of the cabinet, and the internal heat exchange area is connected to the inside of the cabinet, and the compressor does not operate in air-cooled mode, the cabinet air conditioner of this invention, in air-cooled mode, draws cold air from the external heat exchange area to the internal heat exchange area via the channel connecting the two areas, thereby drawing fresh air from outside the cabinet into the cabinet. When the external temperature is low, the cabinet is cooled by the external cold air. The cabinet air conditioner of this invention can effectively utilize the ambient temperature for cooling when the ambient temperature is low, achieving energy-saving and environmentally friendly effects, effectively reducing energy consumption, and improving energy utilization.

[0030] In another aspect, the control method provided by the present invention is based on the above-mentioned cabinet air conditioner, and its beneficial effects are the same as those of the above-mentioned cabinet air conditioner, which will not be repeated here.

[0052] Example 1

[0053] like Figure 1-9 As shown in the figure, an embodiment of the present invention provides a rack air conditioner, which includes a housing 1 and a drive assembly. The housing 1 is provided with a first partition 21 and a second partition 22. The second partition 22 is disposed above the first partition 21. The first partition 21 and the second partition 22 divide the internal space of the housing 1 into an inner heat exchange area and an outer heat exchange area. The inner heat exchange area is connected to the inside of the rack, and the outer heat exchange area is connected to the outside of the rack. An inner fan 31 is provided on one side of the second partition 22 in the inner heat exchange area. When switching from cooling mode to air-cooling mode, the drive assembly can drive the second partition 22 to move upward, and the inner fan 31 can draw air from the outer heat exchange area to the inner heat exchange area.

[0054] In this embodiment, the rack air conditioner includes a housing 1 and a drive assembly. The housing 1 can be integrally mounted on the rack door. A first partition 21 and a second partition 22 are disposed inside the housing 1. The second partition 22 is positioned above the first partition 21. The first partition 21 and the second partition 22 divide the internal space of the housing 1 into an inner heat exchange area and an outer heat exchange area. The inner heat exchange area communicates with the interior of the rack, and the outer heat exchange area communicates with the exterior of the rack. An internal fan 31 is disposed on one side of the second partition 22 in the inner heat exchange area. The rack air conditioner of this embodiment has a cooling mode and a fan-cooled mode. When switching from cooling mode to fan-cooled mode, the drive assembly can drive the second partition 22 to move upwards. After the second partition 22 moves upward, a channel connecting the external heat exchange area and the internal heat exchange area is formed between the lower part of the second partition 22 and the top of the first partition 21. At this time, the internal fan 31 can draw air from the external heat exchange area to the internal heat exchange area. Since the external heat exchange area is connected to the outside of the cabinet and the internal heat exchange area is connected to the inside of the cabinet, and the compressor does not work in the air-cooled mode, the cabinet air conditioner of this embodiment draws the cold air connected to the outside of the cabinet through the channel connecting the external and internal heat exchange areas to the internal heat exchange area in the air-cooled mode, thereby drawing fresh air from the outside of the cabinet into the cabinet. When the external temperature is low, the cabinet is cooled by the external cold air. The cabinet air conditioner of this embodiment can effectively utilize the ambient temperature to cool the cabinet when the ambient temperature is low, achieving energy-saving and environmentally friendly effects, effectively reducing energy consumption and improving energy utilization.

[0055] In this embodiment, the drive assembly is located inside the housing 1. The drive assembly may include a motor, gears, and racks. The motor is located on the inner wall of the housing 1, the gears are located on the drive shaft of the motor, and the racks are located on the second partition 22, with the length of the racks extending in the vertical direction.

[0056] In this embodiment, temperature sensing elements can be installed inside and outside the cabinet to obtain the real-time temperature inside and outside the cabinet.

[0057] In some embodiments, the external heat exchange area is provided with a condenser 41;

[0058] The condenser 41 is disposed on the second partition 22; or, the condenser 41 and the second partition 22 are an integral structure.

[0059] When switching from cooling mode to air-cooling mode, the drive component can drive the condenser 41 to move upward, so that the second partition 22 moves upward.

[0060] In this embodiment, a condenser 41 is provided in the external heat exchange area. The condenser 41 is mounted on the second partition 22, or the condenser 41 and the second partition 22 are an integral structure. When switching from the cooling mode to the air-cooling mode, the drive assembly can drive the condenser 41 to move upward, thereby causing the second partition 22 to move upward. In this embodiment, the drive assembly can drive the condenser 41 to move upward, which in turn drives the second partition 22 to move upward, thus forming a channel connecting the external heat exchange area and the internal heat exchange area between the lower part of the second partition 22 and the top of the first partition 21. The condenser 41 is mounted on the second partition 22, or the condenser 41 and the second partition 22 are an integral structure; this facilitates modular production, improves space utilization, and enhances the efficiency of installation and disassembly.

[0061] In this embodiment, the rack of the drive assembly is mounted on the condenser 41 and extends vertically.

[0062] In some embodiments, the cabinet air conditioner further includes a liquid cooling system, which includes a liquid cooling heat exchanger 51 disposed on the condenser 41 and located below the second partition 22. When switching from cooling mode to liquid cooling mode, the drive assembly drives the condenser 41 to move upward, and the liquid cooling heat exchanger 51 moves to a position opposite to the internal fan 31.

[0063] In this embodiment, the rack air conditioner also includes a liquid cooling system, which includes a liquid cooling heat exchanger 51. The liquid cooling heat exchanger 51 provides a cold source and is disposed on the condenser 41 and located below the second partition 22. When switching from cooling mode to liquid cooling mode, the drive assembly drives the condenser 41 to move upward. This upward movement of the condenser 41 moves the liquid cooling heat exchanger 51 to a position opposite the internal fan 31. The liquid cooling heat exchanger 51, located below the second partition 22 and above the first partition 21, forms a channel connecting the external and internal heat exchange areas. Therefore, the liquid cooling heat exchanger 51 provides a cold source to cool the interior of the rack. Specifically, the liquid cooling system can be a water-cooled system, with the water source located outside the rack. When the external temperature is low, the liquid cooling system can effectively utilize the lower external temperature to cool the rack, achieving energy-saving and environmentally friendly effects. Moreover, liquid cooling is more effective than air cooling.

[0064] In some embodiments, the liquid cooling system further includes a liquid storage tank 52, a pumping device, an inlet pipe 53, and an outlet pipe 54. The pumping device is disposed in the liquid storage tank 52. One end of the inlet pipe 53 is connected to the pumping device, and the other end of the inlet pipe 53 is connected to the liquid cooling heat exchanger 51. One end of the outlet pipe 54 is connected to the liquid cooling heat exchanger 51, and the other end of the outlet pipe 54 extends into the liquid storage tank 52.

[0065] In this embodiment, the liquid cooling system also includes a liquid storage tank 52, a pumping device, an inlet pipe 53, and an outlet pipe 54. The pumping device is installed inside the liquid storage tank 52. One end of the inlet pipe 53 is connected to the pumping device, and the other end of the inlet pipe 53 is connected to the liquid cooling heat exchanger 51. One end of the outlet pipe 54 is connected to the liquid cooling heat exchanger 51, and the other end of the outlet pipe 54 extends into the liquid storage tank 52 to form a liquid cooling system. In liquid cooling mode, the liquid in the liquid storage tank 52 is driven to circulate in the liquid cooling system by the pumping device to achieve cooling of the cabinet by the liquid cooling system.

[0066] In this embodiment, a temperature sensing element can be installed in the liquid storage tank 52 to obtain the real-time temperature of the liquid in the cabinet liquid storage tank 52.

[0067] In some embodiments, the liquid storage tank 52 is disposed on top of the second partition 22, and the top of the liquid storage tank 52 has a liquid collection opening for collecting rainwater.

[0068] In this embodiment, by setting the liquid storage tank 52 on top of the second partition 22, and having a liquid collection opening on the top of the liquid storage tank 52, rainwater can be collected through the liquid collection opening, achieving the effect of rainwater recycling and water conservation, effectively reducing energy consumption and improving energy utilization.

[0069] In some embodiments, the liquid collection opening is provided with a filter screen 521.

[0070] In this embodiment, a filter screen 521 is provided through the liquid collection opening to filter out impurities such as mud and sand carried in the rainwater, preventing impurities carried in the rainwater collected by the liquid storage tank 52 from clogging the cooling pipes of the liquid cooling system.

[0071] In some embodiments, the external heat exchange area is provided with at least two first tracks 61 extending in a vertical direction, and the condenser 41 is provided with first insert tracks 411 that are inserted in a one-to-one correspondence with the at least two first tracks 61.

[0089] Example 2

[0090] This invention provides a control method for controlling the cabinet air conditioner of Embodiment 1, the control method comprising:

[0091] Turn on the air conditioner in the cabinet and obtain the real-time temperature inside the cabinet;

[0092] When the real-time temperature inside the cabinet is greater than t0, it enters cooling mode;

[0093] Obtain the real-time temperature outside the cabinet;

[0094] When the real-time temperature outside the cabinet is less than t1, the cooling mode is switched to the air-cooling mode. The drive component can drive the second partition 22 to move upward, and the internal fan 31 can draw air from the external heat exchange area to the internal heat exchange area.

[0095] Where t0 is greater than t1.

[0096] In this embodiment, the control method includes:

[0097] When the rack air conditioner is turned on, and the real-time temperature inside the rack is greater than t0, it enters cooling mode.

[0098] When the real-time temperature outside the cabinet is less than t1, the system switches from cooling mode to air-cooling mode. The drive component moves the second partition 22 upward, and the internal fan 31 draws air from the external heat exchange area to the internal heat exchange area. Here, t0 is greater than t1. t0 is the temperature that needs to be maintained inside the cabinet; t1 is the first preset temperature, specifically the temperature at which the outside temperature is relatively low, ensuring that the fresh air can effectively cool the cabinet.

[0099] The rack air conditioner of this embodiment has a cooling mode and a fan-cooled mode. When switching from cooling mode to fan-cooled mode, the drive component can drive the second partition 22 to move upward. After the second partition 22 moves upward, a channel connecting the external heat exchange area and the internal heat exchange area is formed between the lower part of the second partition 22 and the top of the first partition 21. At this time, the internal fan 31 can draw air from the external heat exchange area to the internal heat exchange area. Since the external heat exchange area is connected to the outside of the rack and the internal heat exchange area is connected to the inside of the rack, and the compressor does not work in fan-cooled mode, the rack air conditioner of this embodiment draws the cold air connected to the outside of the rack through the channel connecting the external and internal heat exchange areas to the internal heat exchange area in fan-cooled mode, thereby drawing fresh air from the outside of the rack into the rack. When the external temperature is low, the rack is cooled by the external cold air. The rack air conditioner of this embodiment can effectively utilize the ambient temperature to cool the rack when the ambient temperature is low, achieving energy-saving and environmentally friendly effects, effectively reducing energy consumption and improving energy utilization.

[0100] In this embodiment, temperature sensing elements can be installed inside and outside the cabinet to obtain the real-time temperature inside and outside the cabinet.

[0101] In some embodiments, when the cabinet air conditioner includes a liquid storage tank 52, a condenser 41, a liquid-cooled heat exchanger 51, and a pumping device, and when the real-time temperature outside the cabinet is greater than t1, the control method further includes:

[0102] The real-time temperature and liquid level of the liquid stored in the storage tank 52 are obtained.

[0103] When the real-time temperature of the liquid stored in the liquid storage tank 52 is lower than t2 and the liquid level is higher than the preset liquid level, a liquid level gauge can be installed in the liquid storage tank 52 to determine whether the liquid level is higher than the preset liquid level. The preset liquid level is the liquid level when the liquid storage volume is sufficient. When switching from the cooling mode to the liquid cooling mode, the drive component drives the condenser 41 to move upward, the liquid cooling heat exchanger 51 moves to the position opposite to the internal fan 31, the pumping device starts, and the internal fan 31 starts.

[0104] Where t0 is greater than t2.

[0105] In this embodiment, when the cabinet air conditioner includes a liquid storage tank 52, a condenser 41, a liquid-cooled heat exchanger 51, and a pumping device, and the real-time temperature outside the cabinet is greater than t1, and the liquid storage tank 52 has sufficient liquid volume and a liquid temperature lower than t2, the system switches from cooling mode to liquid cooling mode. The drive component drives the condenser 41 to move upward, and the liquid-cooled heat exchanger 51 moves to a position opposite to the internal fan 31. The pumping device starts, and the internal fan 31 starts. Here, t0 is greater than t2. t0 is the temperature that needs to be maintained inside the cabinet; t2 is the second preset temperature, specifically a relatively low liquid storage temperature to ensure that the liquid cooling can effectively cool the cabinet.

[0106] The cabinet air conditioner in this embodiment also includes a liquid cooling system, which includes a liquid cooling heat exchanger 51. The liquid cooling heat exchanger 51 is used to provide a cold source. It is located on the condenser 41 and below the second partition 22. When switching from cooling mode to liquid cooling mode, the drive assembly drives the condenser 41 to move upward. This upward movement of the condenser 41 moves the liquid cooling heat exchanger 51 to a position opposite the internal fan 31. The liquid cooling heat exchanger 51, located below the second partition 22 and above the first partition 21, forms a channel connecting the external and internal heat exchange areas. Therefore, the liquid cooling heat exchanger 51 provides a cold source to cool the interior of the cabinet. Specifically, the liquid cooling system can be a water-cooled system, and the water source in the liquid cooling system can be located outside the cabinet. When the external temperature is low, the liquid cooling system can effectively utilize the lower external temperature to cool the cabinet, achieving energy-saving and environmentally friendly effects. Moreover, liquid cooling is more effective than air cooling.

[0107] In liquid cooling mode, the liquid in the storage tank 52 is driven by a pump to circulate in the liquid cooling system, thereby cooling the cabinet.

[0108] The liquid storage tank 52 can collect rainwater, achieving rainwater recycling and water conservation, effectively reducing energy consumption and improving energy utilization.

[0109] In this embodiment, a temperature sensing element can be installed in the liquid storage tank 52 to obtain the real-time temperature of the liquid in the cabinet liquid storage tank 52.

[0110] In some implementations, t0 > t2 > t1.

[0111] When the real-time temperature outside the cabinet is lower than t1, air cooling is preferred. When the real-time temperature outside the cabinet is between t2 and t1, the real-time temperature of the liquid in the liquid tank 52 is also between t2 and t1. Liquid cooling is more effective than air cooling, so liquid cooling is preferred in this case. When the real-time temperature outside the cabinet is greater than t2, cooling mode is used.

[0112] In summary, those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the devices, apparatuses, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention.
