Description

Technical Field

[0001] The present invention relates to the technical field of power exchange cabinets, and in particular to an auxiliary heat dissipation device for an energy-saving power exchange cabinet. Background Art

[0002] As a key facility for power storage and distribution, battery swap cabinets are responsible for storing, charging, and quickly replacing batteries. Their complex internal structure includes multiple battery slots for placement, as well as core components such as chargers. During daily operation, the batteries continuously charge and discharge, generating significant heat. Furthermore, the chargers also generate significant heat during operation.

[0003] A method for maintaining constant temperature and heat dissipation of a power exchange cabinet, disclosed in publication number CN115158059B, belongs to the technical field of power exchange cabinets. The method for maintaining constant temperature and heat dissipation of a power exchange cabinet adopts a device for maintaining constant temperature and heat dissipation of the power exchange cabinet, which includes a PLC control mainboard, a temperature sensor, a PWM algorithm speed regulation system, a fan, a water-cooled heat dissipation component, and a semiconductor refrigeration plate. Several temperature sensors are evenly arranged around the inside of the power exchange cabinet. From the perspective of heat dissipation principle, it focuses on achieving constant temperature heat dissipation through precise temperature control, and has strong adaptability to changes in ambient temperature. However, this method is relatively complex in structural design, and requires the arrangement of a large number of temperature sensors, complex control systems, and a variety of heat dissipation, refrigeration, and heating equipment. This not only increases the manufacturing cost of the power exchange cabinet, but may also increase the difficulty of subsequent maintenance due to the large number of equipment.

[0004] A multi-channel heat dissipation system and heat dissipation method for a battery exchange cabinet, with publication number CN118017084A, includes a shell, a back panel and a panel are fixed on both sides of the shell, a plurality of placement spaces are provided in the shell, a placement box is fixed in each placement space, and the placement box is used to install batteries; a plurality of air outlets are fixed on the shell.

[0005] However, the heat dissipation methods used by traditional battery swap cabinets, such as simple natural ventilation or basic fan cooling, have very limited heat dissipation efficiency. This causes a large amount of heat to accumulate inside the cabinet, making it difficult to dissipate quickly and effectively. Over time, excessively high temperatures will have a serious impact on battery performance, causing battery capacity to decay faster and significantly shortening its service life. More seriously, high temperature environments may also cause safety risks, such as battery overheating and fire. In view of this, the development of an efficient and energy-saving auxiliary heat dissipation device for battery swap cabinets has become an urgent need to solve the current heat dissipation problem of battery swap cabinets and ensure their stable and reliable operation.

[0017] (3) Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: 1. The lower ventilation structure forms an upward air flow in the central cavity, and the spiral wind guide structure makes the air flow rise in a spiral shape, which increases the contact area and time with the battery insertion position and other heat-generating components, and fully absorbs heat. The role of the semiconductor cooler is to cool the air rising from the central cavity to this point, so that the air temperature is reduced, forming a "cold on top" state. Together with the "hot on bottom" state formed by the lower ventilation structure, it promotes the upper cold and lower hot air convection in the entire power exchange cabinet, thereby improving the heat dissipation efficiency. 2. The first battery slot and the second battery slot are connected to the central cavity through the second vent, and the outer heat dissipation groove, the first heat dissipation fin and the first vent work together to quickly dissipate the heat of the battery. For the charger, the cold air cooled by the semiconductor refrigerator is combined with the second cooling fan, as well as the upper mounting cavity, inner container and other related structures to achieve efficient heat dissipation of the charger, thereby comprehensively improving the heat dissipation performance of the battery swap cabinet. 3. The first and second battery slots are evenly distributed at equal angles with the central cavity as the center and are arranged crosswise with each other, which not only ensures the symmetry and stability of the battery swap cabinet structure, but also optimizes the use of the space around the cabinet, increases the number of batteries accommodated, and strengthens the air convection path during the heat dissipation process, making the heat dissipation more balanced and efficient. 4. The temperature sensors in the first and second battery slots can monitor the temperature in real time and automatically adjust the operating status of the first cooling fan, the second cooling fan and the semiconductor cooler according to the monitoring data. When the temperature rises, the operating intensity of the cooling equipment is enhanced to ensure the cooling effect; when the temperature drops to an appropriate range, the operating intensity is reduced to achieve the purpose of energy saving and precise heat dissipation, effectively reducing energy consumption.

[0018] 5. The design of each battery insertion position sharing a central cavity only requires building a large central cavity in the center of the battery swap cabinet. Each battery insertion position is connected to it through a second vent, which greatly simplifies the internal layout, avoids space waste, and makes efficient use of the internal space of the battery swap cabinet. This layout is more compact and reasonable. Under the same cabinet size, it ensures that the number of battery insertion positions is met while greatly increasing the heat dissipation area of ​​the battery insertion position.

[0022] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-6As shown, the present invention provides an energy-saving battery exchange cabinet auxiliary heat dissipation device, including a battery exchange cabinet 1 with a cylindrical appearance. A central cavity 105 is opened at the central axis of the battery exchange cabinet 1, which provides a channel for air flow and is the key spatial basis for realizing air convection heat dissipation. A charger 7 is provided on the upper part of the battery exchange cabinet 1, and a lower ventilation structure 5 for supplying air from bottom to top in the central cavity 105 is provided at the lower part of the battery exchange cabinet 1; it is used to form the power for air to flow upward. This airflow from bottom to top absorbs heat from surrounding battery insertion positions and other components during the flow in the central cavity 105, so that the air temperature below increases, forming a "bottom-up heat" state. The outer side of the battery swap cabinet 1 is cross-arranged along its axial direction with several groups of first battery slots 2 and several groups of second battery slots 3. The first battery slots 2 and the second battery slots 3 are both connected to the central cavity 105, so that the air in the central cavity 105 can exchange heat with the battery slots, removing the heat generated by the batteries. A semiconductor cooler 9 is provided between the charger 7 and the upper air outlet of the central cavity 105. Heat is generated during operation, and the cool air is dissipated by the semiconductor cooler 9 and the second cooling fan 8. After the cool air is cooled by the semiconductor cooler 9, it cools the charger 7, absorbing the heat generated by the charger 7. The hot air is then discharged through the third vent 111 on the inner container 109, thereby achieving heat dissipation of the charger 7. A spiral wind guide structure 6 is provided in the central cavity 105, which can realize spiral guidance of the air supply. The heat generated by the battery working in the insertion position is transferred to the surrounding air, and the air flowing from bottom to top in the central cavity 105 enters the insertion position through the second vent 110, mixes with the hot air around the battery, takes away the heat, and realizes the heat dissipation of the battery insertion position. At the same time, this also makes the air temperature in the central cavity 105 further increase, strengthening the "bottom heat" effect. The function of the semiconductor refrigerator 9 is to cool the air rising from the central cavity 105 to this place, so that the air temperature is reduced, forming a "top cold" state. The cooled cold air enters the inner container 109, dissipates heat to the charger 7, and the hot air is discharged through the corresponding vents. The cooling effect of the semiconductor refrigerator 9 and the "bottom hot" state formed by the lower ventilation structure 5 together promote the upper cold and lower hot air convection in the entire battery exchange cabinet, thereby improving the heat dissipation efficiency.

[0024] See the instructions attached Figure 2As shown, each group of first battery slots 2 is provided with more than three equal-angled batteries centered on the central cavity 105, and each group of second battery slots 3 is provided with more than three equal-angled batteries centered on the central cavity 105, so that the batteries can be evenly arranged on the outside of the battery exchange cabinet 1. On the one hand, the symmetry and stability of the structure of the battery exchange cabinet 1 are ensured, and uneven force on the cabinet is avoided due to the concentration of batteries on one side. On the other hand, from the heat dissipation perspective, the equal-angle uniform distribution can allow the hot air rising in the central cavity 105 to more evenly exchange heat with the batteries in each first battery slot 2. Multiple first battery slots 2 and second battery slots 3 dissipate heat at the same time, which increases the heat dissipation area and improves the heat dissipation efficiency.

[0025] A group of adjacent first battery slots 2 and a group of adjacent second battery slots 3 are cross-arranged with each other around the central cavity 105. This cross-arrangement further optimizes the layout of the batteries on the outside of the battery swap cabinet 1. From the perspective of space utilization, the concentrated accumulation of battery slots on the outside of the cabinet is avoided, the space around the cabinet is more reasonably utilized, and the number of batteries accommodated is increased. During the heat dissipation process, the cross-arrangement makes the air flow between different groups of battery slots more complex and efficient. When the hot air rising in the central cavity 105 passes through different groups of battery slots, the air will form a richer convection path due to the cross-arrangement. The hot air shuttles between different slots, which can more fully absorb the heat generated by the battery, enhance the heat dissipation effect, and make the heat dissipation of the entire battery swap cabinet 1 more balanced and efficient.

[0026] See the instructions attached Figure 1 and Figure 3 As shown, a heat dissipation groove 101 is provided on the outer side of the battery swap cabinet 1 for being arranged adjacent to the first battery insertion slot 2 and the second battery insertion slot 3. The heat dissipation groove 101 is located close to the battery insertion slot and can directly receive the heat dissipated to the surrounding area when the battery is in operation. Due to its proximity to the heat source of the battery, the heat dissipation groove 101 can quickly transfer the heat generated by the battery to its own structure, providing a basis for subsequent heat dissipation steps, greatly shortening the heat transfer path, and improving the timeliness of heat dissipation.

[0027] Each heat dissipation groove 101 is provided with a number of evenly distributed first heat dissipation fins 102, which significantly increases the heat dissipation area of ​​the heat dissipation groove 101. According to the principle of heat transfer, the larger the heat dissipation area, the faster the heat dissipation under the same temperature difference. When the heat generated by the battery is transferred to the heat dissipation groove 101, the first heat dissipation fins 102 can quickly disperse the heat into the surrounding air, accelerating the heat dissipation from the battery swap cabinet 1 to the external environment, and effectively reducing the temperature around the battery insertion position.

[0028] A first vent hole 103 is provided between two adjacent first heat sink fins 102 to connect the heat sink groove 101 and the central cavity 105. The central cavity 105 is filled with flowing air sent from the lower ventilation structure. Through the first vent hole 103, this flowing air can enter the heat sink groove 101. On the one hand, the flowing air can remove the heat from the first heat sink fins 102, thereby enhancing the heat dissipation effect, because the heat exchange efficiency between the flowing air and the heat sink fins is higher than that of still air. On the other hand, an air circulation channel is formed between the central cavity 105 and the heat sink groove 101, so that the hot air rising in the central cavity 105 can enter the heat sink groove 101 through the first vent hole 103 and mix with the air in the heat sink groove 101, further promoting heat dissipation. At the same time, the air in the heat sink groove 101 can also flow back to the central cavity 105 through the first vent hole 103, participating in the overall air convection heat dissipation process.

[0029] The heat dissipation groove 101, the first heat dissipation fins 102, and the first vents 103 together form an efficient heat dissipation subsystem. The heat dissipation groove 101 quickly absorbs the heat from the battery, the first heat dissipation fins 102 increase the heat dissipation area and accelerate heat dissipation to the surrounding air, and the first vents 103 introduce flowing air from the central cavity 105 to enhance heat dissipation and form air circulation. This overall structure, from heat collection and dissipation to enhanced air convection, comprehensively improves the heat dissipation capacity of the battery swap cabinet 1 for the battery insertion position, ensuring that the battery operates at an appropriate temperature, improving battery life and the overall performance of the battery swap cabinet.

[0030] See the instructions attached Figure 3 and Figure 5 As shown, the spiral wind guide structure 6 includes a central shaft 601 arranged at the central axis of the central cavity 105, and the outer side of the central shaft 601 is fixedly provided with four or more spiral guide ribs 602 evenly distributed around its axis. The upper end of the central shaft 601 is fixedly connected to the inner wall of the central cavity 105 through two or more suspension rods 603. When the air from the lower ventilation structure 5 enters the central cavity 105, the spiral guide ribs 602 change the flow direction of the air, causing it to rise along a spiral trajectory. Since the spiral airflow path is compared to a straight rise, the contact area and contact time between the air and the battery insertion position and other heat-generating components in the central cavity 105 are greatly increased. According to the principle of heat transfer, the increase in contact area and time can allow the air to absorb heat more fully, thereby significantly improving the heat dissipation efficiency. For example, under the same air flow and temperature difference conditions, the air after spiral guidance can take away more heat, effectively reducing the temperature of the various components in the central cavity 105. The spiral wind guide structure 6 cooperates with other heat dissipation components such as the lower ventilation structure 5 and the heat dissipation groove 101 to jointly promote the air convection heat dissipation cycle in the entire power exchange cabinet 1.

[0031] A second vent hole 110 is provided in the up-down direction on one side of each first battery insertion position 2 and each second battery insertion position 3 near the central cavity 105, and the second vent hole 110 is connected to the central cavity 105. The first battery insertion position 2, the second battery insertion position 3 and the second vent hole 110 work together to build an efficient heat transfer and air circulation system. Through the connection of the second vent hole 110, the heat in the battery insertion position is transferred to the central cavity 105 in a timely manner, and at the same time, the air in the central cavity 105 can enter the battery insertion position and mix with the hot air. This process cooperates with other heat dissipation components such as the lower ventilation structure 5 and the spiral wind guide structure 6 to improve the air convection heat dissipation cycle in the entire battery exchange cabinet 1. It improves the heat dissipation performance of the battery exchange cabinet as a whole, ensures the stable operation of the battery and other components, and improves the working efficiency and reliability of the battery exchange cabinet.

[0032] See the instructions attached Figure 3 and Figure 6 As shown, the lower ventilation structure 5 includes a lower mounting cavity 106 provided in the lower portion of the battery swap cabinet 1. A first cooling fan 501 is provided in the lower mounting cavity 106 for supplying air upward toward the central cavity 105 and for blowing the wind in the central cavity 105 into the heat dissipation groove 101 through the first vent 103. A plurality of fifth vents 502 are evenly distributed on the bottom outer wall of the battery swap cabinet 1. A filter screen 503 is provided at the fifth vent 502. Through the above-mentioned specific structural design, the lower mounting cavity 106, the first cooling fan 501, the fifth vent 502 and the filter screen 503 in the lower ventilation structure 5 cooperate with each other to jointly construct an efficient and stable heat dissipation subsystem. Lower mounting cavity 106 provides a stable installation environment and proper airflow guidance for first cooling fan 501. Acting as the power source, first cooling fan 501 promotes air circulation and enhances localized heat dissipation. Fifth vent 502 ensures an adequate and even air supply. Filter screen 503 maintains internal cleanliness and protects all components. Together, these elements allow for continuous and stable entry of cool air into battery swap cabinet 1, creating effective convection within the cabinet, promptly removing heat generated by components like the battery and achieving efficient heat dissipation.

[0033] An upper mounting cavity 108 is provided at the top of the battery swap cabinet 1. An inner container 109 is provided within the upper mounting cavity 108. This isolates the charger 7 from the outside world, reduces the impact of dust, debris, etc. on the charger, and extends the service life of the charger. In addition, the presence of the inner container 109 allows the wind blown by the second cooling fan 8 to act more concentratedly on the charger 7, thereby improving the heat dissipation efficiency. A support rod 701 for supporting the charger 7 is provided within the inner container 109. A second cooling fan 8 for blowing air toward the charger 7 is provided within the inner container 109. A top cover 104 is provided on the top side of the inner container 109. A third vent 111 is provided on the top cover 104 for connecting the inner container 109 with the outside. The semiconductor cooler 9 is provided on the bottom side of the inner container 109. Through the above-mentioned specific structural design, the upper mounting cavity 108 and inner container 109 provide a stable installation environment and protective space for the charger 7 and related heat dissipation components. The support rod 701 ensures the charger 7 is securely placed. The second cooling fan 8 accelerates air flow to remove heat. The top cover 104 and third vent 111 enable air circulation. The semiconductor cooler 9 lowers the air temperature and enhances the heat dissipation effect. These coordinated functions ensure that the heat generated by the charger 7 during operation is dissipated promptly and effectively, ensuring its normal operation and improving the reliability and stability of the entire battery swap cabinet system.

[0034] An airflow channel is formed between the inner wall of the upper mounting cavity 108 and the outer wall of the inner container 109. The bottom sidewall of the inner container 109 is provided with a number of evenly distributed second heat dissipating fins 114, which are connected to the semiconductor cooler 9. The upper sidewall of the battery swap cabinet 1 is provided with a number of fourth vents 112, which connect the airflow channel to the outside. This specific structural design further improves the heat dissipation system for the charger 7 in the upper portion of the battery swap cabinet 1. The airflow channel expands the air flow path and enhances heat exchange; the second heat dissipating fins 114 cooperate with the semiconductor cooler 9 to enhance air cooling; and the fourth vents 112 enable air circulation and renewal within the airflow channel. These components, in conjunction with the upper mounting cavity 108, inner container 109, and second cooling fan 8, enhance heat dissipation efficiency from multiple perspectives, allowing heat generated by the charger 7 to be dissipated more quickly and thoroughly, comprehensively ensuring the stable operation of the charger 7 and improving the reliability and performance of the entire battery swap cabinet system.

[0035] The outer edge of the top cover 104 protrudes from the outside of the battery exchange cabinet 1, and a number of evenly distributed indicator lights 113 are provided on the lower side of the outer edge of the top cover 104.

[0036] An auxiliary heat dissipation device for an energy-saving battery exchange cabinet also includes a temperature sensor for real-time temperature monitoring. The temperature sensor is arranged in each first battery insertion position 2 and second battery insertion position 3. The temperature sensor is electrically connected to the first cooling fan 501, the second cooling fan 8 and the semiconductor cooler 9, and automatically adjusts the operating status of the heat dissipation device according to the temperature monitoring data.

[0037] Working principle: The first cooling fan 501 in the lower ventilation structure 5 is located in the lower mounting cavity 106 at the lower part of the battery swap cabinet 1. After being filtered by the filter screen 503, the outside air enters the lower mounting cavity 106 through the fifth vent 502 on the bottom outer wall, is blown into the central cavity 105 by the first cooling fan 501, and flows upward.

[0038] The upward airflow within central cavity 105 passes through first and second battery compartments 2 and 3 via second vents 110, removing heat generated by the batteries. Simultaneously, the air flows through first vents 103 into heat dissipation grooves 101, dissipating heat via first heat dissipation fins 102. Spiral guide ribs 602 within central cavity 105 cause the air flowing from the lower ventilation structure to rise in a spiral, increasing the area and duration of contact between the air within central cavity 105 and the surrounding structure, thereby enhancing the heat dissipation effect.

[0039] The semiconductor cooler 9 cools the air that rises there. The cooled air dissipates heat to the charger 7 in the inner container 109.

[0040] The second cooling fan 8 in the inner container 109 blows air toward the charger 7, accelerating the air flow around the charger 7 and improving the heat dissipation efficiency. The third vent 111 on the top cover 104 on the top side of the inner container 109 connects the inner container 109 with the outside, exhausting the hot air. At the same time, the air flow channel formed between the inner wall of the upper mounting cavity 108 and the outer wall of the inner container 109, as well as the second heat dissipation fins 114 on the bottom side wall of the inner container 109 connected to the semiconductor cooler 9, further assist in heat dissipation. The fourth vent 112 on the upper side wall of the battery swap cabinet 1 connects the air flow channel with the outside, exhausting the hot air in the air flow channel.

[0041] Temperature sensors installed in each of the first and second battery slots 2 and 3 monitor the temperature in real time. These temperature sensors are electrically connected to the first cooling fan 501, the second cooling fan 8, and the semiconductor cooler 9. When the temperature rises, the temperature sensors automatically adjust the operating status of these cooling devices based on the monitored data, such as increasing fan speed or activating the semiconductor cooler to enhance cooling. When the temperature drops to an appropriate range, the operating intensity of the cooling devices is reduced accordingly, achieving energy conservation and precise cooling.
