[0002] Low-voltage cabinets are key equipment in low-voltage power distribution systems, primarily used for the distribution, control, protection, and monitoring of electrical energy. Since low-voltage cabinets generate significant heat during operation, which can affect their performance, ensuring stable operation of their internal electrical components and extending equipment life is crucial.
[0003] The relevant technology uses the coordinated work of air conditioning and fans to cool the low-voltage cabinet. On the one hand, the air conditioning will be turned on to lower the temperature of the environment where the low-voltage cabinet is located. On the other hand, fans are installed at the bottom and top of the low-voltage cabinet. The fan at the bottom is used for air intake, and the fan at the top is used for exhaust. After the outside air enters the low-voltage cabinet from the bottom, it leaves from the top to achieve circulating heat dissipation.
[0004] Regarding the above-mentioned related technologies, since there are many components inside the low-voltage cabinet, these components will not only block the flow of air, but also heat the air as it rises, causing the temperature of the air to be higher when it is transmitted to the upper part of the low-voltage cabinet, resulting in a decrease in the heat dissipation efficiency of the low-voltage cabinet. Summary of the Invention

[0019] By adopting the above technical solution, the angle between the target residual direction of the target residual auxiliary device and the preset horizontal direction is adjusted to select the working direction of the target residual auxiliary device. This can reduce the temperature as much as possible while ensuring the gas flow in the low-pressure cabinet, thereby improving the cooling efficiency of the low-pressure cabinet.

[0036] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1 To the attached Figure 11 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.
[0037] The embodiment of the present application discloses a method for cooling a low-voltage cabinet. Figure 1 , the method comprising: Step S101: monitoring the temperature inside and outside the low-voltage cabinet.
[0038] The cabinet temperature refers to the temperature inside the low-voltage cabinet. There can be multiple cabinet temperatures. For example, each storage cavity in the low-voltage cabinet is equipped with a temperature sensor, which obtains the specific value of the cabinet temperature through the temperature sensor.
[0039] The external temperature refers to the ambient temperature outside the low-voltage cabinet. For example, if the low-voltage cabinet is installed in a room, the temperature inside the room is the external temperature.
[0040] Step S102: Calculate the difference between the temperature inside the cabinet and the temperature outside the cabinet to obtain a temperature rise value.
[0041] The temperature rise value directly reflects the internal capacity of the low-voltage cabinet. The higher the temperature rise value, the worse the heat dissipation capacity of the heat dissipation cabinet, and the greater the need to improve the heat dissipation of the low-voltage cabinet.
[0042] Step S103: If the temperature inside the cabinet is greater than the first temperature threshold or the temperature rise value is greater than the second temperature threshold, the abnormal position corresponding to the temperature inside the cabinet is obtained.
[0043] The first temperature threshold is a preset empirical value, which is related to the upper limit of heat resistance of the internal components of the low-voltage cabinet. For example, the first temperature threshold is 60°C.
[0044] The second temperature threshold is a preset empirical value, for example, the second temperature threshold is 40°C.
[0045] Exemplarily, a temperature sensor corresponding to the temperature in the cabinet is determined, and the location of the temperature sensor is set as an abnormal location.
[0046] Step S104: If the abnormal position is located at the bottom or top of the low-voltage cabinet, the cooling device of the low-voltage cabinet is turned on. The cooling device includes an air inlet assembly located at the bottom of the low-voltage cabinet and an air outlet assembly located at the top of the low-voltage cabinet. Several accommodating cavities are provided in the low-voltage cabinet, and auxiliary devices are provided in the accommodating cavities. The auxiliary devices are close to the conduction channel inside the low-voltage cabinet, and the conduction channel runs through the accommodating cavity.
[0047] Optionally, the cooling device adopts a fan.
[0048] For example, please refer to Figure 2 The low-voltage cabinet 20 includes a cooling device, which includes an air inlet assembly 21 located at the bottom of the low-voltage cabinet and an air outlet assembly 22 located at the top of the low-voltage cabinet. Several accommodating cavities 25 are provided in the low-voltage cabinet 20, and auxiliary devices 23 are provided in the accommodating cavities. The auxiliary devices 23 are close to the conductive channels 24 inside the low-voltage cabinet 20, and the conductive channels 24 pass through the accommodating cavities 25. The accommodating cavities 25 are used to place the components of the low-voltage cabinet 20. Furthermore, the accommodating cavities 25 are formed by the provision of partitions 26, which can be metal mesh plates, and air can pass through the partitions 26.
[0049] Optionally, the temperature sensor is set inside the accommodating cavity, so the accommodating cavity corresponding to the abnormal position can be determined by the position of the temperature sensor, and the accommodating cavity corresponding to the abnormal position can be used to determine whether the abnormal position is located at the bottom or top of the low-voltage cabinet. For example, please refer to Figure 2 If the accommodating cavity 251 is at the bottom of the low-voltage cabinet 20, it is considered that the accommodating cavity 251 is located at the bottom of the low-voltage cabinet 20, and it is further considered that the abnormal position is located at the bottom of the low-voltage cabinet 20; if the accommodating cavity 252 is at the top of the low-voltage cabinet 20, it is considered that the accommodating cavity 252 is located at the top of the low-voltage cabinet 20, and it is further considered that the abnormal position is located at the top of the low-voltage cabinet 20.
[0050] If the abnormal position is located at the bottom or top of the low-voltage cabinet, since the cooling device includes an air inlet assembly located at the bottom of the low-voltage cabinet and an air outlet assembly located at the top of the low-voltage cabinet, after the cooling device is turned on, the air inlet assembly will directly act on the abnormal position located at the bottom of the low-voltage cabinet, and the air outlet assembly will directly act on the abnormal position located at the top of the low-voltage cabinet, causing the air at the abnormal position to flow, thereby achieving cooling of the abnormal position.
[0051] Step S105: If the abnormal position is located in the middle of the low-voltage cabinet, determine the cavity number of the abnormal position in the low-voltage cabinet.
[0052] The cavity number uniquely identifies the internal cavity of the low-voltage cabinet. The cavity number can be numbered from top to bottom or from bottom to top.
[0053] Optionally, if the abnormal position is not located at the bottom or the top of the low-voltage cabinet, it is considered that the abnormal position is located in the middle of the low-voltage cabinet.
[0054] Step S106: Determine the target auxiliary device corresponding to the cavity number.
[0055] For example, please refer to Figure 2 , an auxiliary device 23 is provided in each accommodating cavity 25 , and if the abnormal position is located in the accommodating cavity 25 , the auxiliary device 231 in the accommodating cavity 25 is regarded as a target auxiliary device.
[0056] Step S107: Turn on the cooling device and simultaneously turn on the target auxiliary device, so that the target auxiliary device draws air from the conduction channel.
[0057] For example, please refer to Figure 2 When the auxiliary device 231 is the target auxiliary device and the auxiliary device 231 is working, one end of the auxiliary device 231 draws air from the conduction channel 24 and the other end blows out air. The air in the conduction channel 24 is sent from the outside into the low-voltage cabinet 20 by the air inlet component 21. The air in the conduction channel 24 is less affected by the components inside the accommodating cavity during the flow process, so its temperature is lower and it has a better cooling effect.
[0058] By adopting the above technical solution, the temperature inside the cabinet and the temperature rise value are combined to determine whether overheating occurs inside the low-voltage cabinet, and the abnormal location is determined after overheating occurs. If the abnormal location is in the middle of the low-voltage cabinet, the target auxiliary device and the conduction channel are used to achieve cooling. Because the conduction channel runs through the accommodating cavity, the temperature of the air flowing in the conduction channel is relatively low. When the target auxiliary device is used, it will draw air from the conduction channel to ensure that the temperature of the air used for cooling is relatively low, thereby improving the cooling efficiency of the low-voltage cabinet.
[0059] In the following embodiment, if two abnormal positions appear, it is necessary to open two auxiliary devices at the same time. At this time, the operation of the auxiliary devices will affect each other. In order to reduce this influence, the embodiment of the present application discloses a method for operating the auxiliary device. Figure 3 , the method comprising: Step S301: When there are two abnormal locations, determine a first abnormal location and a second abnormal location.
[0060] In some embodiments, the first abnormal position and the second abnormal position both refer to positions of the temperature sensor in the accommodation cavity.
[0061] In some embodiments, the temperature sensor may be an infrared sensor. In this case, the temperature inside the cabinet at various locations within the accommodating cavity may be acquired through the infrared sensor. In this case, a specific location may be considered as an abnormal location.
[0062] Step S302: Determine a first auxiliary position corresponding to the first abnormal position and a second auxiliary position corresponding to the second abnormal position.
[0063] For example, please refer to Figure 4 , the auxiliary device 231 is located below the auxiliary device 232, then the auxiliary device 231 is the first auxiliary device, and the auxiliary device 2332 is the second auxiliary device.
[0064] Furthermore, when the first auxiliary device is working, it will extract some air from the conduction channel, causing the temperature of the air drawn from the conduction channel by the second auxiliary device to be higher, affecting the cooling of the second abnormal position by the second auxiliary device.
[0065] Step S303: Obtaining a first angle according to the relative positional relationship between the position of the first auxiliary device and the first abnormal position.
[0066] Taking the position of the first auxiliary device as the origin, emitting light toward the first abnormal position to obtain a first ray, and taking the angle between the first ray and the ray in the vertical upward direction to obtain a first angle.
[0067] For example, please refer to Figure 4 , taking the position of the first auxiliary device 231 as the origin, emitting toward the first abnormal position 41 to obtain the first ray.
[0068] Step S304: obtaining a second angle according to the relative positional relationship between the position of the first auxiliary device and the second abnormal position.
[0069] Taking the position of the first auxiliary device as the origin, emitting light toward the second abnormal position to obtain a second ray, and taking the angle between the second ray and the ray in the vertical upward direction to obtain a second angle.
[0070] For example, please refer to Figure 4 , taking the position of the first auxiliary device 231 as the origin, emitting toward the second abnormal position 42 to obtain a second ray.
[0071] Step S305: controlling the working direction of the first auxiliary device to swing between the first angle and the second angle.
[0072] The working direction refers to the blowing direction of the auxiliary device.
[0073] Controlling the working direction of the first auxiliary device to swing between the first angle and the second angle can not only cool down the first abnormal position and the second abnormal position, but also compensate for the influence of the deviation of the cooling effect of the second auxiliary device.
[0074] Step S306: controlling the working direction of the second auxiliary device to align with the second abnormal position.
[0075] By controlling the working direction of the second auxiliary device to align with the second abnormal position, the second auxiliary device can cool down the abnormally high temperature at the second abnormal position to ensure the normal operation of the low-voltage cabinet as much as possible.
[0076] By adopting the above technical solution, when there are two abnormal locations, the first auxiliary device and the second auxiliary device are determined, and the operating direction of the first auxiliary device is swung between the first angle and the second angle, while the operating direction of the second auxiliary device is controlled to align with the second abnormal location. The operation of the first auxiliary device not only cools the two abnormal locations but also promotes air flow within the containment cavity, thereby improving the cooling efficiency of the low-voltage cabinet.
[0077] In the following embodiments, during the operation of both the first auxiliary device and the second auxiliary device, the temperature of the first abnormal position or the second abnormal position may still be too high, affecting the normal operation of the low-voltage cabinet. Therefore, the embodiment of the present application discloses a second operating method of the auxiliary device. Figure 5 , the method comprising: Step S501: monitoring a first temperature inside the cabinet at a first abnormal position and a second temperature inside the cabinet at a second abnormal position.
[0078] The first temperature inside the cabinet refers to the temperature at the first abnormal position or the temperature inside the accommodation cavity corresponding to the first abnormal position.
[0079] The second cabinet internal temperature refers to the temperature at the second abnormal position or the temperature in the accommodation cavity corresponding to the second abnormal position.
[0080] Step S502: In response to detecting that the temperature inside the first cabinet is greater than a first temperature threshold, controlling the working direction of the first auxiliary device to align with the first abnormal position.
[0081] When the temperature inside the first cabinet is detected to be greater than the first temperature threshold, it indicates that the temperature at the first abnormal location is too high and there is a risk of overheating at the first abnormal location. Therefore, the working direction of the first auxiliary device is controlled to be aligned with the first abnormal location, so that the first auxiliary device continuously cools the first abnormal location to minimize the temperature at the first abnormal location.
[0082] Step S503: in response to detecting that the temperature inside the second cabinet is greater than the first temperature threshold, controlling the working direction of the first auxiliary device to align with the second abnormal position.
[0083] If the temperature inside the second cabinet is detected to be greater than the first temperature threshold, it indicates that the temperature at the second abnormal location is too high and there is a risk of overheating at the second abnormal location. Therefore, the working direction of the first auxiliary device is controlled to align with the second abnormal location, so that the first auxiliary device continuously cools the second abnormal location to minimize the temperature at the first abnormal location.
[0084] Step S504: If the temperature inside the second cabinet is greater than the first temperature threshold within a preset time period, the operating power of the first auxiliary device is reduced, and the operating power of the second auxiliary device is increased.
[0085] The preset duration is a preset empirical value, for example, the preset duration is 2 minutes.
[0086] If the temperature inside the second cabinet is detected to be greater than the first temperature threshold for a predetermined period of time, it indicates that the temperature at the second abnormal location is persistently abnormal, and the cooling measures in step S502 have little effect on the second abnormal location. Therefore, in this step, the operating power of the first auxiliary device is reduced and the operating power of the second auxiliary device is increased. While reducing the impact of the first auxiliary device on the conduction channel, the temperature of the air delivered to the containment cavity by the second auxiliary device is kept low, and the operating power of the second auxiliary device is increased to ensure the cooling effect of the second auxiliary device.
[0087] By adopting the above technical solution, when it is detected that the temperature inside the first cabinet at a first abnormal location is greater than a first temperature threshold, the operating direction of the first auxiliary device is controlled to align with the first abnormal location, thereby ensuring the cooling effect at the first abnormal location. When it is detected that the temperature inside the second cabinet at a second abnormal location is greater than the first temperature threshold, the operating direction of the first auxiliary device is controlled to align with the second abnormal location. If it remains greater than the first temperature threshold for a preset period of time, the first auxiliary device is shut down and the operating power of the second auxiliary device is increased, thereby reducing the impact of the first auxiliary device on the air in the conduction channel, ensuring the cooling effect of the second auxiliary device, and thereby improving the cooling efficiency of the low-voltage cabinet.
[0088] In the following embodiments, during the operation of the auxiliary device, it is necessary to pay real-time attention to the changes in the temperature inside the cabinet. When the temperature inside the cabinet further increases, corresponding measures need to be taken to ensure the cooling efficiency of the low-voltage cabinet. Therefore, the embodiment of this application discloses a joint control method for auxiliary devices. Figure 6 , the method comprising: Step S601: In response to detecting that the temperature inside the cabinet is greater than a third temperature threshold, determining a lower-layer auxiliary device of the target auxiliary device, where the third temperature threshold is greater than the first temperature threshold.
[0089] The third temperature threshold is a preset empirical value, for example, the third temperature threshold is 70°C.
[0090] The lower auxiliary device is located in the receiving cavity of the layer below the target auxiliary device. For example, if the target auxiliary device is located in the third receiving cavity from top to bottom in the low-voltage cabinet, the lower auxiliary device is the auxiliary device in the fourth receiving cavity.
[0091] Step S602: setting a lower-level target direction according to the positional relationship between the abnormal position and the lower-level auxiliary device.
[0092] For example, a line is drawn connecting the abnormal position and the position of the lower auxiliary device to obtain a direction line. On the direction line, the direction from the position of the lower auxiliary device to the abnormal position is taken to obtain the target direction.
[0093] Step S603: setting the operating power of the lower auxiliary device according to the difference between the temperature inside the cabinet and the first temperature threshold.
[0094] In some embodiments, the difference between the cabinet temperature and a first temperature threshold is calculated to obtain a temperature deviation value. The operating power corresponding to the temperature deviation value is determined from a preset temperature-power mapping table. The temperature-power mapping table is used to record the mapping relationship between temperature and operating power. The temperature-power mapping table can be obtained by technicians through repeated experiments.
[0095] Step S604: Turn on the lower auxiliary device according to the working power, and control the lower auxiliary device to work towards the target direction.
[0096] Exemplarily, after the lower auxiliary device is turned on, the power of the lower auxiliary device is adjusted to the working power, and the working direction of the lower auxiliary device is adjusted to the target direction.
[0097] By adopting the above technical solution, when it is detected that the temperature inside the cabinet is greater than the third temperature threshold, the lower auxiliary device will be turned on, and the lower auxiliary device will be used to cool the abnormal position, thereby quickly reducing the temperature at the abnormal position and achieving rapid cooling of the low-voltage cabinet.
[0098] In the following embodiment, if the temperature of the air in the conduction channel is too high, it will affect the cooling effect of the target auxiliary device. Therefore, it is necessary to monitor the air temperature in the conduction channel to ensure that the auxiliary device can absorb air with lower temperature. Therefore, the embodiment of this application discloses a joint control method 2 for the auxiliary device. Figure 7 , the method comprising: Step S701: monitor the temperature in the conduction channel to obtain the conduction temperature.
[0099] Optionally, a temperature sensor is also provided in the conduction channel, and the conduction temperature is obtained by reading the temperature sensor.
[0100] Furthermore, a plurality of temperature sensors are provided in the conduction channel, and the reading of the temperature sensor closest to the target auxiliary device is taken as the conduction temperature.
[0101] Step S702: when the conduction temperature is greater than a fourth temperature threshold, determining a shielding auxiliary device according to the target auxiliary device, wherein the shielding auxiliary device is located between the target auxiliary device and the air inlet assembly.
[0102] The fourth temperature threshold is a preset empirical value, and technicians can adjust the specific value of the fourth temperature threshold according to actual needs.
[0103] Alternatively, if the cavity numbers are arranged from bottom to top, after determining the cavity number n corresponding to the target auxiliary device, the cavity number is subtracted by one to obtain n-1. The auxiliary devices corresponding to the cavities numbered 1 to n-1 are used as shielding auxiliary devices.
[0104] For example, please refer to Figure 8 , when the target auxiliary device is the auxiliary device 231 , the shielding auxiliary device is the auxiliary device 233 .
[0105] Step S703: Turn on the shielding auxiliary device and control the working direction of the shielding auxiliary device to be vertically upward.
[0106] The power of the shielding auxiliary device is adjusted according to the power of the air supply assembly so that the wind speed corresponding to the shielding auxiliary device is consistent with the wind speed corresponding to the air supply assembly.
[0107] When the working direction of the shielding auxiliary device is vertically upward, the wind blown out by the shielding auxiliary device can form a wind wall, and the wind speed corresponding to the shielding auxiliary device is consistent with the wind speed corresponding to the air supply component, which can separate the air in the accommodating cavity from the conduction channel, so that the air flows quickly along the conduction channel, and can reduce the amount of air entering the accommodating cavity from the conduction channel, and can also reduce the amount of air in the accommodating cavity entering the conduction channel.
[0108] For example, please refer to Figure 8 The working direction of the control auxiliary device 233 is vertically upward.
[0109] Step S704: determining a blocking auxiliary device according to the target auxiliary device, where the blocking auxiliary device is located in an upper accommodating cavity than the accommodating cavity where the target auxiliary device is located.
[0110] Alternatively, if the cavity numbers are arranged from bottom to top, after determining the cavity number n corresponding to the target auxiliary device, the cavity number is increased by one to obtain n+1. The auxiliary device corresponding to the cavity number n+1 is used as the blocking auxiliary device.
[0111] Step S705: Turn on the blocking auxiliary device and control the working direction of the blocking auxiliary device to face the conducting channel.
[0112] The working direction of the blocking auxiliary device forms an acute angle with the horizontal direction, and the working direction is higher than the horizontal direction.
[0113] When the blocking auxiliary device is turned on and its working direction is controlled to be toward the conduction channel, the air blown out by the blocking auxiliary device can be used to limit the air flow in the conduction channel so that the air will not continue to flow above the target auxiliary device.
[0114] For example, please refer to Figure 8 , the auxiliary device 232 is an auxiliary blocking device, By adopting the above technical solution, if the temperature in the conduction channel is greater than the fourth temperature threshold, the shielding auxiliary device and the blocking auxiliary device will be turned on. The working direction of the shielding auxiliary device is vertically upward, and the working direction of the blocking auxiliary device is toward the conduction channel. An isolation zone can be formed between the conduction channel and the accommodating cavity, and the air with lower temperature can be directly sent to the target auxiliary device.
[0115] In the following embodiments, for auxiliary devices other than the target auxiliary device, the shielding auxiliary device and the blocking auxiliary device, these auxiliary devices are located above the target auxiliary device and cannot be cooled using the conduction channel. Therefore, these auxiliary devices are prone to overheating and require separate heat dissipation treatment. Therefore, the embodiment of the present application discloses a third joint control method for auxiliary devices. Figure 9 , the method comprising: Step S901: determining a remaining auxiliary device according to the shielding auxiliary device, where the remaining auxiliary device is located between the shielding auxiliary device and the air outlet assembly.
[0116] The air outlet assembly includes a first air outlet subassembly and a second air outlet subassembly. The first air outlet subassembly is used to ventilate the accommodating cavity, and the second air outlet subassembly is used to ventilate the conduction channel.
[0117] For example, please refer to Figure 8 , the remaining auxiliary devices are auxiliary device 234 and auxiliary device 235.
[0118] Step S902: Obtain the remaining cabinet temperatures corresponding to the remaining auxiliary devices.
[0119] The temperature inside the remaining cabinet refers to the temperature inside the accommodating cavity corresponding to the remaining auxiliary devices. Optionally, the temperature inside the remaining cabinet can be measured by a temperature sensor inside the corresponding accommodating cavity.
[0120] Step S903: If a target remaining cabinet temperature among the remaining cabinet temperatures is greater than a first temperature threshold, a target remaining auxiliary device corresponding to the target remaining cabinet temperature is determined.
[0121] The target remaining cabinet temperature is any one of the remaining cabinet temperatures. The target remaining auxiliary device is any one of the remaining auxiliary devices.
[0122] Step S904: determining a working surplus auxiliary device according to the target surplus auxiliary device, where the working surplus auxiliary device is located between the target surplus auxiliary device and the air outlet assembly.
[0123] For example, please refer to Figure 8 , if the target remaining auxiliary device is auxiliary device 234 , then the working remaining auxiliary device is auxiliary device 235 .
[0124] Step S905: Turn on the work-remaining auxiliary device, so that the working direction of the work-remaining auxiliary device is vertically downward.
[0125] When the work surplus auxiliary device is turned on and the working direction of the work surplus auxiliary device is vertically downward, the air in the accommodating cavity and the conduction channel can be separated, so that the air flows quickly along the conduction channel, and the amount of air entering the accommodating cavity from the conduction channel can be reduced, and the amount of air in the accommodating cavity entering the conduction channel can also be reduced.
[0126] Step S906: Turn on the second air outlet subassembly to allow the second air outlet subassembly to ventilate the interior of the low-voltage cabinet.
[0127] When the second air outlet subassembly is activated to ventilate the interior of the low-voltage cabinet, it partially ventilates the conduction channel. The target residual auxiliary device uses the air provided by the second air outlet subassembly to cool the containment cavity. Furthermore, because the shielding auxiliary device is in operation, it divides the conduction channel into two sections, minimizing interference between them.
[0128] By adopting the above technical solution, after the target residual auxiliary device appears in the residual auxiliary device, the working residual auxiliary device will be turned on, so that the working direction of the working residual auxiliary device is vertically downward, and the second air outlet sub-assembly will be turned on to send the air with lowered temperature to the target residual auxiliary device to achieve cooling and ensure the cooling efficiency of the low-voltage cabinet.
[0129] The present application embodiment discloses a joint control method 4 of an auxiliary device. Figure 10 , the method comprising: Step S1001: determining a high temperature area corresponding to a target remaining auxiliary device according to a target remaining cabinet temperature.
[0130] Exemplarily, the target remaining cabinet temperature is compared with a first temperature threshold, and a region where the target remaining cabinet temperature is greater than the first temperature threshold is selected to obtain a high-temperature region.
[0131] Step S1002: generating a target remaining direction according to the relative positional relationship between the high temperature area and the target remaining auxiliary device.
[0132] Exemplarily, the position of the target residual auxiliary device is directed to a vector of the high temperature area, and the direction of the vector is used as the target residual direction.
[0133] Step S1003: If the angle between the target remaining direction and the preset horizontal direction is positive, the target remaining auxiliary device is controlled to operate according to the target remaining direction.
[0134] For example, in Figure 8 In the viewing angle shown, the preset horizontal direction is the horizontal rightward direction. If the vertical component of the target residual direction is the vertical upward direction, the angle between the target residual direction and the preset horizontal direction is considered to be positive.
[0135] Step S1004: If the angle between the target remaining direction and the preset horizontal direction is negative, the target remaining auxiliary device is controlled to operate in the preset horizontal direction.
[0136] If the component of the target residual direction in the vertical direction is in the vertical downward direction, the angle between the target residual direction and the preset horizontal direction is considered to be negative.
[0137] If the target residual auxiliary device is controlled to work in the target residual direction, it will cause serious interference between the wind blown out by the target residual auxiliary device and the wind sent in by the air inlet component, which will greatly reduce the cooling effect of the target residual auxiliary device.
[0138] By adopting the above technical solution, the angle between the target residual direction of the target residual auxiliary device and the preset horizontal direction is adjusted to select the working direction of the target residual auxiliary device. This can reduce the temperature as much as possible while ensuring the gas flow in the low-pressure cabinet, thereby improving the cooling efficiency of the low-pressure cabinet.
[0139] Based on the same inventive concept, an embodiment of the present application provides a cooling system for a low-voltage cabinet, comprising: An acquisition module 1101 is used to acquire the temperature inside the cabinet, the temperature outside the cabinet, and the abnormal location; Memory 1102, used to store the program of the cooling method of the low-voltage cabinet; Processor 1103, the program in the memory can be loaded and executed by the processor to implement the above-mentioned low-voltage cabinet cooling method.
[0140] By adopting the above technical solution, the temperature inside the cabinet and the temperature rise value are combined to determine whether overheating occurs inside the low-voltage cabinet, and the abnormal location is determined after overheating occurs. If the abnormal location is in the middle of the low-voltage cabinet, the target auxiliary device and the conduction channel are used to achieve cooling. Because the conduction channel runs through the accommodating cavity, the temperature of the air flowing in the conduction channel is relatively low. When the target auxiliary device is used, it will draw air from the conduction channel to ensure that the temperature of the air used for cooling is relatively low, thereby improving the cooling efficiency of the low-voltage cabinet.
