Description

Technical Field

[0001] The present invention relates to the technical field of communication base station cabinets, and in particular to a cold channel cabinet with a ladder battery compartment. Background Art

[0002] With the continuous improvement of the country's information level, various businesses in the communications industry are developing rapidly. With the rapid expansion of business volume and network scale, the promotion of the Internet of Things, big data, and large capacity, as well as the popularization of 4G mobile networks and subsequent 5G mobile networks, higher requirements are also placed on the cabinet design and layout of communication base stations.

[0003] Among them, the backup power supply used in the cabinet of traditional communication base stations is mainly lead-acid batteries, and the suitable operating temperature of this type of battery is about 25°C. In recent years, based on the advocacy of energy conservation and consumption reduction and effective use of resources, second-life batteries are now gradually put into use in cabinets as backup power supplies. However, since second-life batteries are resistant to high temperatures (can operate normally at 40°C) but not to low temperatures, the lead-acid batteries in the cabinet cannot be directly replaced with second-life batteries: on the one hand, when the external ambient temperature is low, an additional heater needs to be installed in the cabinet to heat the second-life batteries to a suitable operating temperature, resulting in high energy consumption, uneconomical, and occupied cabinet space. On the other hand, since the communication equipment in the cabinet is unstable in heating all year round, using it in an unstable state will cause the second-life batteries to be flammable and explosive, thereby increasing the risk factor of cabinet operation and making the cabinet operation unreliable.

[0004] In addition, traditional communication base station cabinets mainly use wall-mounted air conditioners to disperse cold air between the compartments in the cabinet so that each compartment shares the same temperature. However, this type of wall-mounted air conditioner, especially in a cabinet with multiple compartments, is prone to causing local overtemperature, that is, the compartment temperature near the air outlet of the wall-mounted air conditioner is significantly different from the compartment temperature far from the air outlet of the wall-mounted air conditioner, resulting in uneven distribution of cold air in the cabinet, affecting the reliability of the cabinet operation. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a cold channel cabinet with a tiered battery compartment, which does not require an additional heater, has a more reasonable layout, operates more reliably and stably, and has lower energy consumption.

[0006] The present invention discloses a cold channel cabinet with a secondary battery compartment, comprising a cabinet body, wherein a battery compartment for placing secondary batteries, a power compartment for placing power equipment, an air-conditioning compartment for placing refrigeration equipment, and a plurality of communication equipment compartments for placing communication equipment are installed in the cabinet body, the communication equipment compartment is located at one side of the cabinet body, and the battery compartment, the power compartment and the air-conditioning compartment are sequentially arranged at the other side of the cabinet body from top to bottom, and the heat generated by the power equipment can be transferred from the bottom of the battery compartment to the secondary batteries through the power compartment; a cold channel connected to the air outlet of the refrigeration equipment in the air-conditioning compartment is also arranged in the cabinet body, and each communication equipment compartment is connected to the cold channel, and the cold air generated by the refrigeration equipment is continuously transported to each communication equipment compartment through the cold channel, and the hot air in the communication equipment compartment is returned to the refrigeration equipment through the air outlet of the communication equipment compartment, so that the air flow in the cabinet body circulates, thereby realizing cooling in the cabinet body.

[0007] Preferably, the battery compartment is a fully enclosed compartment body made of partitions.

[0008] Further preferably, the partitions on the sides of the battery compartment are made of fireproof and explosion-proof insulating materials; and the partitions at the bottom of the battery compartment are made of heat-conductive metal materials.

[0009] Preferably, a fire extinguishing device is also provided on the top of the battery compartment.

[0010] Preferably, the cold channel is surrounded by a top surface structure in the shape of a letter "7", a side surface structure corresponding to the air flow hole, and the side surface and bottom surface of the cabinet.

[0011] Preferably, the cold channel is located at the lower end of the communication equipment compartment, and air flow holes are provided on the front side and / or the rear side of the cold channel, and the cold air of the cold channel enters each communication equipment compartment through the air flow holes.

[0012] Preferably, the cold channel is located below the communication equipment compartment, and air flow holes are provided on the top side of the cold channel, and each of the communication equipment compartments is connected to the cold channel through the air flow holes.

[0013] Further preferably, the air flow hole is provided with an air volume adjustment member for adjusting the output volume of the cold air.

[0014] More preferably, the air volume adjusting member is a scaled air regulating baffle or a temperature control valve.

[0015] Preferably, the refrigeration equipment is an integrated air conditioner or an integral cabinet air conditioner.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The communication equipment compartment in the cold channel cabinet is located on one side of the cabinet, while the battery compartment, power supply compartment and air conditioning compartment are arranged in sequence from top to bottom on the other side of the cabinet, and the power supply compartment and the battery compartment are in heat transfer contact, and no additional heater is required, that is, the heat generated by the power supply equipment can be transferred from the bottom of the battery compartment to the secondary battery through the power supply compartment, so that the secondary battery can reach a suitable operating temperature, thereby reducing energy consumption and saving the internal space of the cabinet, so that the layout of each compartment in the cabinet is more reasonable and the reliability of the cabinet operation is improved; moreover, compared with the traditional cooling method of distributing the cold air of the wall-mounted air conditioner to each communication equipment compartment, since the refrigeration equipment in the cold channel cabinet is connected to the inside of each communication equipment compartment through the cold channel, the cold channel can deliver the cold air generated by the refrigeration equipment to the inside of each communication equipment compartment, so that the cold air distribution is more uniform, avoiding local overheating, improving the cooling efficiency, and saving energy consumption. Therefore, the communication equipment and the secondary battery can operate within their respective suitable operating temperature ranges, ensuring the reliability and stability of the cabinet operation.

DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] A cold channel cabinet with a ladder battery compartment of the present invention, referring to Figure 1 , including a cabinet 1, in which a battery compartment 3 for placing a second-life battery 2, a power compartment 6 for placing a power supply device 5 (such as a distribution unit, an embedded power supply, etc.), an air-conditioning compartment 8 for placing a refrigeration device 7, and multiple communication equipment compartments 13 for placing communication equipment 12 are installed, wherein a standard rack for placing the communication equipment 12 can be set in the communication equipment compartment 13.

[0022] Among them, the communication equipment compartment 13 is located on the right side of the cabinet 1, and the battery compartment 3, the power supply compartment 6 and the air-conditioning compartment 8 are arranged in sequence from top to bottom on the left side of the cabinet 1. Specifically, the battery compartment 3 and the air-conditioning compartment 8 are respectively located at the top and bottom of the cabinet 1, and the power supply compartment 6 is located at the bottom of the battery compartment 3. The heat generated by the power supply device 5 can be transferred to the secondary battery 2 from the bottom partition of the battery compartment 3 through the power supply compartment 6, so that there is no need to set up an additional heater to continue heating the battery compartment 3, and the temperature of the secondary battery 2 can be automatically increased to reach a suitable temperature for normal operation. In this way, by recycling the heat emitted by the power supply device 5 in the cabinet when it is working, the secondary battery 2 can operate normally without the need for heating by an additional heater, only using the heat emitted by the power supply device 5 when it is working. This not only reduces energy consumption, but also saves the internal space of the cabinet, thereby making the layout of each compartment in the cabinet more reasonable and improving the reliability of the cabinet operation.

[0023] The battery compartment 3 is a fully enclosed compartment body made of partitions. Specifically, the partitions at the bottom of the battery compartment 3 are made of heat-conductive metal materials (such as metal sheets) to improve the thermal conductivity efficiency, so that the heat generated by the power supply device 5 can be better transferred to the secondary batteries 2 in the battery compartment 3; the partitions on the sides of the battery compartment 3 are made of fireproof and explosion-proof insulating materials. When the temperature instability occurs in other locations in the cabinet 1 except the battery compartment 3, the fully enclosed compartment body can minimize the impact of the temperature instability on the secondary batteries 2 in the battery compartment 3, thereby reducing the risk of failure of the secondary batteries 2, thereby protecting other equipment in the cabinet 1.

[0024] A fire extinguishing device 4 is also provided on the top of the battery compartment 3 to further reduce the risk factor and improve the reliability of the cabinet.

[0025] In this embodiment, in order to achieve uniform cooling, a cold channel 9 connected to the air outlet of the refrigeration device 7 is also provided in the cabinet 1, and each communication equipment compartment 13 is connected to the cold channel 9, so that the cold air generated by the refrigeration device 7 can be transported to the inside of each communication equipment compartment 13 through the cold channel 9, so that the cold air distribution is more uniform, thereby avoiding local overheating, and the hot air in the communication equipment compartment 13 is sequentially returned to the return air outlet of the refrigeration device 7 through the air outlet of the communication equipment compartment 13, so that the refrigeration device 7 cools the communication equipment compartment 13, and then the refrigeration device 7 re-transports the cold air from the air outlet through the cold channel 9 to each communication equipment compartment 13 to promote the air flow circulation in the cabinet 1, and achieve continuous cooling, so as to achieve the purpose of good cooling effect and high cooling efficiency, thereby saving energy consumption and ensuring the stable operation of the cabinet. Among them, the refrigeration device 7 is an integrated air conditioner or an integral cabinet air conditioner; in this way, the indoor air flow circulation is separated from the outdoor air flow circulation and does not affect each other.

[0026] The cold channel 9 is formed by a top surface structure in the shape of "7", a side structure corresponding to the air flow hole 10, and the side and bottom surfaces of the cabinet 1. This arrangement can fully utilize the side and bottom surfaces of the cabinet 1 and save more materials.

[0027] In this embodiment, the cold channel 9 is arranged at the lower end of the communication equipment warehouse 13, and the front side and / or the rear side of the cold channel 9 are provided with air flow holes 10. The cold air of the cold channel 9 enters each communication equipment warehouse 13 through the air flow holes 10. In this way, the cold air of the cold channel 9 can enter each communication equipment warehouse 13 in a direction parallel to the bottom surface of the communication equipment warehouse 13 after passing through the air flow holes 10. Furthermore, the air flow holes 10 are arranged at the front side and / or the rear side of the cold channel 9 instead of on the top surface of the cold channel 9. This can avoid the direct collision of the cold air flow and the hot air flow in the communication equipment warehouse caused by the cold air entering each communication equipment warehouse in a direction perpendicular to the bottom surface of the communication equipment warehouse in the prior art, thereby obtaining a more uniform airflow and achieving an ideal heat exchange effect.

[0028] Alternatively, the cold channel 9 is sunk and installed below the communication equipment compartment 13 (such as directly setting the cold channel 9 in the base of the cabinet 1 located below the communication equipment compartment 13), and the cold channel 9 is connected to the air outlet of the refrigeration equipment 7 by an air duct, and an air flow hole 10 is set on the top side of the cold channel 9, and the cold air of the cold channel 9 enters each communication equipment compartment 13 through the air flow hole 10; such a setting can avoid the communication equipment 12 at the lower end of the communication equipment compartment 13 not being well cooled down due to the cold channel 9 being located at the lower end of the communication equipment compartment 13 and the air flow hole 10 being located at the top side of the cold channel 9. Therefore, such a setting of the cold channel 9 can make each communication equipment 12 in the communication equipment compartment 13 be well cooled, so that more communication equipment 12 can be accommodated in the communication equipment compartment 13, thereby improving the utilization rate of the internal space of the cabinet.

[0029] An air volume adjustment member 11 is provided at the air flow hole 10 to adjust the output of cold air, so that the cold air can be more reasonably distributed, the heat dissipation of the cabinet is more uniform, and the versatility is strong. The air volume adjustment member 11 is specifically a scaled air adjustment baffle or a temperature control valve. Among them, the scaled air adjustment baffle can slide left and right at the air flow hole 10 to adjust the size of the air flow hole corresponding to each communication equipment compartment 13 according to the heat generation in different communication equipment compartments 13 or the number of communication equipment 12.

[0030] The working principle of the cold channel cabinet is as follows: the refrigeration equipment 7 transports cold air from the bottom of the cabinet 1 through the cold channel 9 to each communication equipment compartment 13, and adjusts the air regulating plate or temperature control valve according to the heat generation of the communication equipment 12 in each communication equipment compartment 13, and the input cold air gradually exchanges heat with the hot air in the communication equipment compartment 13 to reduce the overall temperature in the communication equipment compartment 13, and the hot air in the communication equipment compartment 13 can flow back to the refrigeration equipment 7 through the air outlet of the communication equipment compartment 13, so that the refrigeration equipment 7 completes the heat exchange and cooling in the communication equipment compartment 13, and then the refrigeration equipment 7 transports the cold air from the air outlet through the cold channel 9 again to each communication equipment compartment 13, and so on and so forth, so as to promote the airflow circulation in the cabinet, and then can continuously cool down, and realize the uniform heat dissipation and cooling in the cabinet (refer to Figure 1 The power supply device 5 in the power supply compartment 6 will emit heat when working, and part of the heat will be transferred to the secondary battery 2 through the partition between the power supply compartment 6 and the battery compartment 3, which not only ensures that the secondary battery 2 works within a suitable temperature range, but also reduces the temperature of the power supply device 5 to ensure that it can operate at a suitable temperature. The airflow that continuously flows out from the communication equipment compartment 13 will flow through the power supply compartment 6 and then reach the refrigeration equipment 7. The flowing airflow will take away part of the heat emitted by the power supply device 5, thereby reducing the temperature of the power supply device 5 and ensuring its normal operation. The layout of each compartment in the cold channel cabinet is reasonable, so that the communication equipment 12, the power supply equipment 5 and the secondary battery 2 can all operate within their respective suitable operating temperature ranges, thereby improving the reliability and stability of the cabinet operation. Moreover, the compartment assembly can shorten the installation time of the cabinet and improve the efficiency of new site construction.
