Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a cabinet and a control method. Background Art

[0002] A notable feature of 5G communications equipment is its high power consumption. To prevent local hotspots and ensure normal operation, a large amount of cooling capacity is required. In base stations and transmission convergence rooms, C-RAN deployments involve the centralization of numerous BBUs within a single cabinet. Heat dissipation in a single cabinet can exceed 5kW or even 10kW, making heat dissipation a significant issue affecting equipment performance. Traditional room-level cooling methods are ineffective and inefficient.

[0003] The traditional heat dissipation method in communication rooms is centralized cooling. Since there is often a certain distance between multiple cabinets and air conditioners, the cold air in the room is gradually lost during transmission due to the mixing of hot and cold air currents. When it is delivered to the vicinity of the cabinet, the air temperature will be higher than the air supply temperature of the air conditioner. If the heat density of the cabinet is very high, local hot spots can easily occur, affecting the normal operation of the equipment. If the air flow inside the cabinet is not smooth, the local hot spot problem will become more serious. When the air conditioner is placed inside the cabinet, there is also the problem of not being able to change the cooling mode. For various application scenarios, it is impossible to match different cooling modes to different application scenarios and equipment power consumption. In addition, the existing cabinet air conditioning refrigeration terminal occupies too much space inside the cabinet, reducing the number of communication equipment installed in the cabinet.

[0004] The present invention is proposed in view of this. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a cabinet having an air conditioning unit therein that occupies a small space and can adjust the corresponding operating mode according to various heat dissipation scenarios. The cabinet can switch between multiple modes according to load conditions and environmental conditions, fully utilizing existing cooling sources to reduce cooling energy consumption, and dynamically adjusting the cooling mode according to load conditions and ambient temperature to achieve precise and dynamic cooling.

[0006] The present invention also provides a cabinet control method.

[0007] A cabinet according to an embodiment of the first aspect of the present invention includes:

[0008] A cabinet body, wherein a receiving chamber for receiving equipment is formed inside the cabinet body;

[0009] an air conditioning device, disposed at the bottom of the accommodating chamber;

[0010] The air conditioning device includes a housing, and a heat exchanger is arranged inside the housing;

[0011] The shell surface is provided with a first air conditioning valve and a second air conditioning valve for opening and closing air entering the internal channel of the shell;

[0012] The surface of the housing is also provided with a plurality of fans for providing power for air to enter and exit the interior of the housing;

[0013] Wherein, the air outside the housing enters the interior of the housing through the first air-conditioning valve and / or the second air-conditioning valve under the action of the fan;

[0014] Under the action of the fan, the air inside the housing flows out of the housing through the fan or flows out of the housing from the fan after heat exchange in the heat exchanger.

[0015] According to one embodiment of the present invention, the fans are evenly distributed on one side close to the edge of the first surface of the housing;

[0016] The first air conditioning valve is arranged at the other side edge of the first surface relative to the fan;

[0017] The second air conditioning valve is arranged on the second surface of the housing;

[0018] Wherein, the second surface is connected to a side of the first surface where the fan is provided.

[0019] Specifically, by setting up a first air-conditioning valve, a second air-conditioning valve and a heat exchanger that can be independently controlled to open and close, the air-conditioning device can provide a variety of heat dissipation solutions according to a variety of heat dissipation scenarios, thereby ensuring the heat dissipation of the cabinet. At the same time, the air-conditioning device is placed inside the cabinet, so that the air-conditioning is close to the heat source, and the near-end cooling is shortened, thereby shortening the air supply distance between the air-conditioning terminal and the heat source, so that all the cooling capacity can be fully utilized, reducing cooling loss, and thus improving the heat dissipation efficiency of the equipment inside the cabinet.

[0020] According to one embodiment of the present invention, the cabinet is provided with an air inlet valve and an air exhaust valve;

[0021] The air inlet valve is provided on the first side wall of the cabinet and corresponds to the second air conditioning valve, and is used to open and close the passage for air to enter the interior of the cabinet;

[0022] The exhaust valve is provided on the top wall of the cabinet body near the second side wall, and is used to open and close the passage for air to be discharged from the cabinet body;

[0023] The first side wall is arranged opposite to the second side wall.

[0024] Specifically, an air inlet valve corresponding to the second air-conditioning valve is provided on the cabinet, so that air outside the cabinet can be introduced into the interior of the cabinet, and an exhaust valve is provided on the top wall to discharge the air inside the cabinet.

[0025] According to a second aspect of an embodiment of the present invention, a control method for the cabinet is applied to a user terminal, comprising the following steps:

[0026] Obtain environmental parameters of the cabinet's surroundings and feed them back to the control system;

[0027] The cabinet status corresponding to the environmental parameters is calculated by the control system;

[0028] Searching for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes an adjustment decision corresponding to each cabinet state;

[0029] Performs scaling decisions on the enclosure.

[0030] According to one embodiment of the present invention, the step of obtaining environmental parameters of the cabinet surrounding environment and feeding the environmental parameters back to the control system specifically includes:

[0031] The internal temperature parameters of the environment inside the cabinet and the external temperature parameters of the environment outside the cabinet are obtained, the internal temperature parameters and the external temperature parameters are packaged, and sent to the control system.

[0032] Specifically, by obtaining the ambient temperature inside and outside the cabinet, it is possible to switch the cabinet's various working modes according to the internal and external temperatures, achieving intelligent adjustment.

[0033] According to one embodiment of the present invention, the step of searching for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes an adjustment decision corresponding to each cabinet state, specifically includes:

[0034] When the cabinet state satisfies that the internal temperature parameter is higher than the preset internal temperature value of the control system, and the external temperature parameter is higher than the preset first external temperature value of the cabinet, the control system calls the air conditioning operation mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state;

[0035] The air conditioning operation mode includes opening the first air conditioning valve, closing the second air conditioning valve, the air inlet valve and the air exhaust valve, and starting the fan and the heat exchanger.

[0036] Specifically, by obtaining the ambient temperature inside and outside the cabinet, if the environment outside the cabinet cannot provide cooling, or there are many devices installed inside the cabinet and there are areas with high heat density, then by selecting the adjustment decision, the air-conditioning operation mode is selected to adjust the valves and other equipment of the cabinet and the air-conditioning, and the cooling of the equipment inside the cabinet is achieved through the refrigeration system of the air-conditioning device itself.

[0037] According to one embodiment of the present invention, the step of searching for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes an adjustment decision corresponding to each cabinet state, specifically includes:

[0038] When the cabinet state satisfies the condition that the internal temperature parameter is higher than the preset internal temperature value of the control system, and the external temperature parameter is lower than the preset first external temperature value of the cabinet and higher than the preset second external temperature value, the control system calls the partial cooling mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state;

[0039] The partial cooling mode includes opening the first air conditioning valve, the second air conditioning valve, the air inlet valve, the air exhaust valve and the heat exchanger, and starting the fan.

[0040] Specifically, by obtaining the ambient temperature inside and outside the cabinet, the environment outside the cabinet can provide a certain amount of cooling, but it cannot meet the heat dissipation needs of all equipment, or the cooling capacity of the environment outside the cabinet can meet the heat dissipation needs of the equipment in the initial construction stage, but as the equipment increases, the cooling capacity of the environment becomes insufficient. At this time, by selecting the adjustment decision, some cooling modes are selected to adjust the valves and other equipment of the cabinet and air conditioner. The cabinet and air conditioner are adjusted through the joint action of the air conditioning unit's own cooling system and the cold air outside the cabinet.

[0041] According to one embodiment of the present invention, the step of searching for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes an adjustment decision corresponding to each cabinet state, specifically includes:

[0042] When the cabinet state satisfies the condition that the internal temperature parameter is higher than the preset internal temperature value of the cabinet, and the external temperature parameter is lower than the preset second external temperature value of the control system, and higher than the preset third external temperature value, the control system calls the natural cooling mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state;

[0043] The natural cooling mode includes opening the second air conditioning valve, the air inlet valve and the exhaust valve, closing the first air conditioning valve and the heat exchanger, and starting the fan.

[0044] Specifically, by obtaining the ambient temperature inside and outside the cabinet, the cooling capacity of the environment outside the cabinet is sufficient to meet the heat dissipation requirements inside the cabinet. At this time, by selecting the adjustment decision, the natural cooling mode is selected to adjust the valves and other equipment of the cabinet and air conditioner. By shutting down the refrigeration system of the air conditioner itself, the cold air outside the cabinet is used to adjust the cabinet and the air conditioner.

[0045] According to one embodiment of the present invention, the step of searching for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes an adjustment decision corresponding to each cabinet state, specifically includes:

[0046] When the cabinet state satisfies that the external temperature parameter is lower than the preset third external temperature value of the control system, the control system calls the closed loop mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state;

[0047] The closed cycle mode includes opening the first air conditioning valve, closing the second air conditioning valve, the air inlet valve, the air exhaust valve and the heat exchanger, and starting the fan.

[0048] Specifically, by obtaining the ambient temperature inside and outside the cabinet, if the external ambient temperature of the cabinet is too low, there is no need to introduce cooling capacity outside the cabinet or provide air-conditioning cooling capacity, then by selecting the adjustment decision, the closed circulation mode is selected to adjust the valves and other equipment of the cabinet and air conditioner. By turning off the refrigeration system of the air-conditioning device, the fan is used to realize the self-circulation of the air inside the cabinet, and the waste heat of the equipment is used to heat the air inside the cabinet to avoid affecting the use of the equipment due to too low temperature.

[0049] According to one embodiment of the present invention, the step of searching for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes an adjustment decision corresponding to each cabinet state, specifically includes:

[0050] When the cabinet status is that the external power supply is off, the control system calls the emergency cooling mode in the adjustment strategy as the adjustment decision corresponding to the cabinet status;

[0051] The emergency cooling mode includes opening the second air conditioning valve, air inlet valve and exhaust valve, closing the first air conditioning valve and heat exchanger, and starting the fan;

[0052] Among them, the power supply for the fan is provided by the backup power supply.

[0053] Specifically, by obtaining the ambient temperature inside and outside the cabinet, in the event of a sudden power outage, the equipment is still running, causing the air inside the cabinet to heat up rapidly. There is a backup power supply in the computer room to supply power to the air-conditioning fan. At this time, by selecting the adjustment decision, the emergency cooling mode is selected to adjust the valves and other equipment of the cabinet and air conditioner, power the fan with the backup power supply, and make corresponding settings for the opening and closing of the valve. The flow of air inside and outside the cabinet is used to achieve heat dissipation and cooling of the equipment inside the cabinet.

[0054] The above one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: the present invention proposes a cabinet, in which the air-conditioning device arranged inside occupies a small space and is suitable for a variety of heat dissipation scenarios. It can switch between multiple modes according to load conditions and environmental conditions, make full use of existing cold sources to reduce cooling energy consumption, and realize dynamic adjustment of the cooling mode according to load conditions and ambient temperature, so as to achieve precise cooling and dynamic cooling.

[0099] In one embodiment, Figure 4 As shown, the step of obtaining the environmental parameters of the environment surrounding the cabinet and feeding the environmental parameters back to the control system specifically includes: obtaining the internal temperature parameters of the internal environment of the cabinet and the external temperature parameters of the external environment of the cabinet, encapsulating the internal temperature parameters and the external temperature parameters, and sending them to the control system.

[0100] Specifically, by obtaining the ambient temperature inside and outside the cabinet, it is possible to switch the cabinet's various working modes according to the internal and external temperatures, achieving intelligent adjustment.

[0101] In one embodiment, Figure 5 As shown, the control system searches for an adjustment decision corresponding to the cabinet state from the adjustment strategy preset by the control system, wherein the adjustment strategy includes the step of making an adjustment decision corresponding to each cabinet state, specifically including: when the cabinet state satisfies that the internal temperature parameter is higher than the preset internal temperature value of the control system, and the external temperature parameter is higher than the preset external first temperature value of the cabinet, the control system calls the air-conditioning operation mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state; the air-conditioning operation mode includes opening the first air-conditioning valve 3, closing the second air-conditioning valve 4, the air inlet valve 7 and the exhaust valve 8, and starting the fan 5 and the heat exchanger 2.

[0102] Specifically, by obtaining the ambient temperature inside and outside the cabinet, if the environment outside the cabinet cannot provide cooling, or there are many devices installed inside the cabinet and there are areas with high heat density, then by selecting the adjustment decision, the air-conditioning operation mode is selected to adjust the valves and other equipment of the cabinet and the air-conditioning, and the cooling of the equipment inside the cabinet is achieved through the refrigeration system of the air-conditioning device itself.

[0103] In one embodiment, Figure 6As shown, the control system searches for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes the step of making an adjustment decision corresponding to each cabinet state, specifically including: when the cabinet state satisfies that the internal temperature parameter is higher than the preset internal temperature value of the control system, and the external temperature parameter is lower than the preset external first temperature value of the cabinet, and higher than the preset external second temperature value, the control system calls the partial cooling mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state; the partial cooling mode includes opening the first air-conditioning valve 3, the second air-conditioning valve 4, the air inlet valve 7, the exhaust valve 8 and the heat exchanger 2, and starting the fan 5.

[0104] Specifically, by obtaining the ambient temperature inside and outside the cabinet, the environment outside the cabinet can provide a certain amount of cooling, but it cannot meet the heat dissipation needs of all equipment, or the cooling capacity of the environment outside the cabinet can meet the heat dissipation needs of the equipment in the initial construction stage, but as the equipment increases, the cooling capacity of the environment becomes insufficient. At this time, by selecting the adjustment decision, some cooling modes are selected to adjust the valves and other equipment of the cabinet and air conditioner. The cabinet and air conditioner are adjusted through the joint action of the air conditioning unit's own cooling system and the cold air outside the cabinet.

[0105] In one embodiment, Figure 7 As shown, the control system searches for the adjustment decision corresponding to the cabinet state from the adjustment strategy preset by the control system, wherein the adjustment strategy includes the steps of making an adjustment decision corresponding to each cabinet state, specifically including: when the cabinet state satisfies that the internal temperature parameter is higher than the preset internal temperature value of the cabinet, and the external temperature parameter is lower than the preset external second temperature value of the control system, and is higher than the preset external third temperature value, the control system calls the natural cooling mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state; the natural cooling mode includes opening the second air-conditioning valve 4, the air inlet valve 7 and the exhaust valve 8, closing the first air-conditioning valve 3 and the heat exchanger 2, and starting the fan 5.

[0106] Specifically, by obtaining the ambient temperature inside and outside the cabinet, the cooling capacity of the environment outside the cabinet is sufficient to meet the heat dissipation requirements inside the cabinet. At this time, by selecting the adjustment decision, the natural cooling mode is selected to adjust the valves and other equipment of the cabinet and air conditioner. By shutting down the refrigeration system of the air conditioner itself, the cold air outside the cabinet is used to adjust the cabinet and the air conditioner.

[0107] In one embodiment, Figure 8As shown, the control system searches for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes the step of making an adjustment decision corresponding to each cabinet state, specifically including: when the cabinet state satisfies that the external temperature parameter is lower than a preset external third temperature value of the control system, the control system calls the closed loop mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state; the closed loop mode includes opening the first air-conditioning valve 3, closing the second air-conditioning valve 4, the air inlet valve 7, the exhaust valve 8 and the heat exchanger 2, and starting the fan 5.

[0108] Specifically, by obtaining the ambient temperature inside and outside the cabinet, the external ambient temperature of the cabinet is too low, and there is no need to introduce cooling capacity outside the cabinet or provide air-conditioning cooling capacity. At this time, by selecting the adjustment decision, the closed circulation mode is selected to adjust the valves and other equipment of the cabinet and air conditioner. By turning off the refrigeration system of the air-conditioning device, the fan 5 is used to realize the self-circulation of the air inside the cabinet, and the waste heat of the equipment is used to heat the air inside the cabinet to avoid affecting the use of the equipment due to too low temperature.

[0109] In one embodiment, Figure 9 As shown, the control system searches for an adjustment decision corresponding to the cabinet state from an adjustment strategy preset by the control system, wherein the adjustment strategy includes the step of making an adjustment decision corresponding to each cabinet state, specifically including: when the cabinet state is that the external power supply is off, the control system calls the emergency cooling mode in the adjustment strategy as the adjustment decision corresponding to the cabinet state; the emergency cooling mode includes opening the second air-conditioning valve 4, the air inlet valve 7 and the exhaust valve 8, closing the first air-conditioning valve 3 and the heat exchanger 2, and starting the fan 5; wherein, the power supply for the fan 5 is provided by the backup power supply.

[0110] Specifically, by obtaining the ambient temperature inside and outside the cabinet, if the mains power is cut off but the equipment is still running, the air inside the cabinet will heat up rapidly. There is a backup power supply in the computer room to supply power to the air-conditioning fan 5. At this time, by selecting the adjustment decision, the emergency cooling mode is selected to adjust the valves and other equipment of the cabinet and air conditioner, power the fan 5 with the backup power supply, and set the opening and closing of the valve accordingly. The flow of air inside and outside the cabinet is used to achieve heat dissipation and cooling of the equipment inside the cabinet.

[0111] It should be noted that the preset external first temperature value, the preset external second temperature value and the preset external third temperature value refer to three preset temperature values of the cabinet exterior. The preset external first temperature value means that the external ambient temperature of the cabinet is too high and is not suitable for cooling the interior of the cabinet. The preset external second temperature value means that the temperature outside the cabinet is moderate and the air outside the cabinet can be used to cool the interior of the cabinet. The preset external third temperature value means that the external ambient temperature of the cabinet is too low and is likely to affect the operation of the equipment inside the cabinet. No specific numerical value is set for the preset external ambient temperature. In actual application, it can be selected according to actual conditions.
