Description
Technical Field
The invention mainly relates to the technical field of UPS cabinets, in particular to a heat management structure of a UPS cabinet.
Background
The UPS is one kind of constant voltage and constant frequency uninterrupted power supply with energy accumulator and inverter as main component. The system is mainly used for providing uninterrupted power supply for a single computer, a computer network system or other power electronic equipment. When the mains supply is interrupted, the UPS immediately supplies 220V alternating current to the load by an inversion conversion method, so that the load keeps normal work and soft and hardware of the load are protected from damage. UPS devices typically provide protection against both excessive and too low voltages.
In low temperature environments, UPS cabinets face a number of challenges. For lithium batteries in UPS systems, low temperatures can affect the electrochemical reaction kinetics inside the lithium battery. Under low temperature conditions, the ionic conductivity of the electrolyte decreases and the rate of ion diffusion in the electrode material decreases. This results in a reduction in the number of active lithium ions available to the battery during discharge, resulting in a reduction in the available capacity of the battery. For example, at-20 ℃, the capacity of a lithium battery may be only 50% -70% at normal temperature (specific values for different types of lithium batteries vary). At the same time, the internal resistance of the battery increases, which causes a larger voltage drop during charge and discharge, further affecting the performance of the battery, reducing the output power of the battery, so that the device may not obtain sufficient power supply at low temperatures. In addition, other electronic components within the UPS cabinet, such as circuit boards, inverters, etc., may change their electrical performance parameters at low temperatures. The carrier mobility of the semiconductor device decreases with temperature, which may cause problems of element switching speed variation, signal transmission delay, etc., and meanwhile, thermal expansion and cold contraction caused by low temperature may cause poor contact or damage of elements, affecting the stability and reliability of the whole UPS system.

The simple heating mode in the prior art only uniformly heats the whole cabinet, and the temperature difference requirements of different areas in the cabinet are not considered, especially for a large UPS cabinet containing a plurality of lithium batteries. Moreover, some heating systems do not have precise control over temperature, which can lead to localized overheating, which is also detrimental to lithium batteries and other electronic components. In addition, the temperature adjustment lacks flexibility, the heating strategy cannot be timely adjusted according to actual environmental temperature change and the load condition of the UPS system, the energy utilization is not efficient, and unnecessary energy waste can be caused.

Working principle:
In a low temperature environment, the heating assembly 3 is activated to generate hot gas. The hot air is conveyed into the UPS cabinet body 1 through the air conveying pipeline 4.
When the system is not started or the heat supply to a specific area is not needed, the first electric push rod 451 is in a default position, the valve body 452 is in a state of closing the branch pipe 42, and hot air cannot enter the corresponding lithium battery 2 area through the branch pipe 42.
When it is desired to deliver hot gas to the space around one or more lithium batteries 2, the control system drives first electric push rod 451 to retract. The action of the first electric push rod 451 drives the valve body 452 to slide on the branch pipe 42, so that the valve body 452 opens the channel of the branch pipe 42, and at this time, the hot air in the main pipe 41 enters the branch pipe 42 through the air delivery cavity 43 and is discharged from the air discharge hole 44, so as to heat the area where the corresponding lithium battery is located. By controlling the valve bodies 452 on each of the branch conduits 42, hot gas supply control to the areas of the UPS cabinet 1 where different lithium batteries are located can be achieved. Because each branch pipeline 42 corresponds to different lithium battery areas, whether to convey hot air to the areas can be independently determined according to the actual temperature requirement of each area, the accurate heating of the areas is realized, the ineffective heat supply of the areas which do not need to be heated is avoided, and the energy utilization efficiency is improved.
The open/close state of each control valve 45 can be dynamically adjusted during the whole heating process according to the temperature data of different areas fed back by the temperature sensor. For example, when the temperature of a certain lithium battery area is low, the corresponding control valve 45 is opened for heating, and when the temperature is raised to a proper range, the valve is closed. The flexible control mode is beneficial to maintaining the uniformity and stability of the temperature inside the cabinet body, and ensures that each lithium battery can work in a proper temperature environment.
When the zone temperature reaches a set point or no further heating is required, the control system again drives the first electric push rod 451 to return the valve body 452 to the original position, closing the branch conduit 42 and stopping the delivery of hot gas.
The temperature regulating mechanism 8 is started to perform auxiliary regulation when the following conditions occur:
1. when the external environment temperature of the UPS cabinet 1 is greatly reduced, such as in cold winter or in a low-temperature special environment, the heating of the interior of the cabinet by the hot gas generated by the heating assembly 3 through the gas pipeline 4 may not be sufficient to maintain the optimal operating temperature of the lithium battery 2 and other devices. At this time, the temperature adjusting mechanism 8 can further distribute the hot air generated by the heating component 3 to a required area, that is, by docking with the temperature adjusting valve 5 at different positions, the heating effect on the specific area inside the UPS cabinet 1 is enhanced, and the temperature is ensured to be uniformly raised to a proper range.
2. Although there is a gas pipe 4 for carrying out hot gas transportation to the cabinet, a situation that the temperature difference is large at different positions in the cabinet may occur due to the cabinet structure, the layout of the lithium battery 2 or other factors. For example, the temperature of the area near the edge of the cabinet or near the air inlet is lower, while the temperature of the central area is relatively higher. The temperature adjusting mechanism 8 can accurately convey the hot air of the heating component 3 to a region with lower temperature according to temperature information of different regions fed back by the temperature sensor, so that the temperature in the cabinet body is more uniform, and all lithium batteries 2 are guaranteed to be in a good temperature environment.
3. The temperature regulating mechanism 8 may cooperate with the heating assembly 3 to regulate the temperature locally when a temperature sensor mounted on or around the lithium battery 2 detects that the temperature of one or more lithium batteries deviates from the normal operating temperature range. If the temperature of a certain lithium battery is too low, the temperature regulating mechanism 8 guides the hot air of the heating component 3 to the area where the lithium battery is located, and the temperature of the lithium battery is increased through the corresponding temperature regulating valve 5, so that the influence on the performance and the service life of the lithium battery due to the too low local temperature is avoided. If the temperature of a certain lithium battery is too high, the temperature regulating mechanism 8 guides cold air to the area where the lithium battery 2 is located, and the temperature of the lithium battery is increased through the corresponding temperature regulating valve 5, so that the influence on the performance and the service life of the lithium battery due to the local too high temperature is avoided.
4. During operation of the UPS system, changes in load may result in changes in the heat generation and distribution within the cabinet. For example, when the load suddenly increases, the heat generation amount of the UPS device itself increases, which may affect the temperature balance inside the cabinet. If the temperature sensor detects that abnormal fluctuation occurs in the temperature of the cabinet at this time, the temperature adjusting mechanism 8 can work cooperatively with the heating component 3 according to actual conditions, adjust the temperatures of different areas and maintain a stable running environment.
In the auxiliary temperature adjustment process, the second motor 61 is started to drive the driving synchronous pulley 62 to rotate, and the driven synchronous pulley 64 is driven to rotate through the synchronous belt 65, so that the driving lifting block 66 moves along with the synchronous belt 65. The driving lifting block 66 drives the sliding block 67 to slide on the guide rail 68, and meanwhile, the stable operation of the whole lifting mechanism 6 is ensured through the connected driven lifting block 69. The docking mechanism 7 mounted on the driving elevating block 66 and the driven elevating block 69 is elevated accordingly.
The first motor 51 drives the gear 53 to rotate through the first transmission assembly 52. The gear 53 drives the first rack 54 and the second rack 55 on the left side and the right side to move reversely, the first rack 54 drives the upper valve 57 through the first connecting block 56, the second rack 55 drives the lower valve 59 through the second connecting block 58, so that the opening degree of the air inlet is adjusted, the external air quantity entering the UPS cabinet 1 is controlled, and the corresponding temperature regulating valve 5 can be controlled according to the temperature requirement of each row of lithium batteries 2.
When the temperature of the temperature-adjusting valve 5 at a specific position is required, the third motor 77 is started. The power of the third motor 77 is transmitted to the driving shaft 72 through the second transmission assembly 78, so that the driving shaft 72 starts to rotate. The two driving wheels 73 on the driving shaft 72 rotate along with the shaft, and the driving wheels 73 and the driven wheels 75 are driven by the connecting belt 76, so that the rotation of the driving wheels 73 drives the connecting belt 76 to move, and the driven wheels 75 rotate along with the connecting belt 76. During the movement of the connecting belt 76, the temperature adjusting mechanism 8 fixed at the upper end of the connecting belt 76 moves along with the connecting belt until the temperature adjusting mechanism 8 moves to a position corresponding to the target temperature adjusting valve 5, so as to realize butt joint and prepare for the conveying operation of hot air or cold air.
And in the hot gas conveying process, when hot gas needs to be conveyed to the temperature regulating valve 5, the hot gas generated by the heating assembly 3 enters the gas distribution pipeline 81 through the hot gas pipeline 84. At this time, the fan 82 is started, the fan 82 rotates to enable hot air to form directional air flow in the air distribution pipeline 81, and after the air flow passes through the filter 83 and the filter 83 to filter impurities such as dust possibly carried in the hot air in the process, the hot air is conveyed into the UPS cabinet 1 through the temperature regulating valve 5 in butt joint with the air distribution pipeline 81, so that the heating of corresponding areas in the cabinet is realized.
And in the cold air conveying process, when the temperature of the interior of the cabinet body needs to be reduced, the second electric push rod 87 is started to push the air door 86 to move downwards, and the cold air inlet 85 is opened. The external cold air enters the air distribution pipeline 81 from the cold air inlet 85 under the action of the fan 82, and is guided and accelerated by the fan 82, and then the cold air is conveyed into the UPS cabinet 1 through the temperature regulating valve 5. In this process, the filter 83 also filters the incoming air to prevent contaminants from entering the cabinet.
When hot air or cold air is not needed to be conveyed, the fan 82 stops rotating, and if cold air is conveyed before, the second electric push rod 87 drives the air door 86 to close the cold air inlet 85, so that the stable state in the air distribution pipeline 81 is maintained, and the influence of random inlet and outlet of external air on the temperature of the cabinet body is avoided. The temperature environment of the lithium battery 2 in different areas in the UPS cabinet body 1 is controlled by the temperature regulating mechanism 8. By controlling the transport of hot or cold air, the temperature in the UPS cabinet 1 can be effectively regulated. When the temperature in the cabinet body is too high or local cooling is needed in the temperature balancing process, cold air can be conveyed, the temperature around each lithium battery 2 can be flexibly adjusted according to the actual temperature condition of the lithium batteries, the UPS system can be ensured to stably operate in a proper temperature environment, the temperature in the cabinet body is kept in a range suitable for the operation of the lithium batteries 2 and other equipment, and the performance and the service life of the equipment are ensured.
