Description
Technical Field
[0001] This invention relates to the field of energy storage equipment technology, specifically to a novel mobile energy storage power supply trailer with a double-layer heat dissipation chassis structure. Background Technology
[0002] Mobile energy storage power supply trailers are widely used in mobile scenarios such as emergency power supply and outdoor operations. They are equipped with energy storage devices, which are energy devices that can store electrical energy and release it on demand. The core is to convert electrical energy into a storable form of energy through energy storage batteries, and then convert it back into electrical energy output according to demand. Traditional energy storage enclosures have fixed internal structures and low modularity. The rigid layout of each functional area cannot adapt to multiple specifications of energy storage components (such as battery cabinets of different specifications). They cannot flexibly adjust the internal space layout of the energy storage enclosure to achieve fine allocation of internal space, resulting in unreasonable internal space allocation and low space utilization. Furthermore, the batteries and electronic control components of energy storage devices generate a lot of heat during operation. The internal layout of traditional energy storage enclosures is messy, and the heat dissipation path is affected by the messy environment inside the energy storage enclosure, which makes it impossible to achieve efficient and rapid heat dissipation, resulting in poor heat dissipation and low heat dissipation efficiency of energy storage devices during operation. Moreover, traditional energy storage enclosures use a single shell structure, which has a limited heat dissipation area and low heat exchange efficiency. This can easily lead to heat accumulation during equipment operation and cause local overheating problems. At the same time, the single shell has poor thermal insulation performance, making it easy for internal heat to be lost in winter and external heat to be intruded in summer. This makes it difficult to adapt to wide temperature range conditions and affects the stable operation of energy storage equipment. Summary of the Invention
[0003] To address the above problems, this invention provides a novel double-layer heat dissipation chassis structure for a mobile energy storage power supply trailer, which solves the aforementioned issues.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a novel mobile energy storage power trailer double-layer heat dissipation chassis structure, including a trailer body and an energy storage chassis installed on the trailer body, wherein a support mechanism is connected inside the energy storage chassis; The support mechanism includes a chassis frame, which is installed in an energy storage chassis. A number of bottom beams are connected to one side of the chassis frame, and fixed beams are connected to both sides of the chassis frame. A number of mounting beams are installed on one side of each fixed beam, and cabinet clips are connected to the middle of each mounting beam. A number of reinforcing columns are connected to one side of the energy storage chassis, and one side of each reinforcing column is connected to the bottom beams and mounting beams. One side of the chassis frame is connected to a fixed beam two, and the top of the two bottom beams is connected to a support frame. Several support beams are connected between the support frame and the fixed beam two, and a high-voltage box clamp is connected to one side of two of the support beams. The top of the other two support beams is connected to a charger mounting plate.
[0005] Preferably, the top of the two bottom beams is connected to an electrical cabinet fixing plate, and a cabinet controller is connected to one side of the chassis frame. The cabinet controller is located on one side of the electrical cabinet fixing plate.
[0006] Preferably, the bottom of the energy storage enclosure is connected to a mounting frame, the mounting frame is connected to one side of the trailer body, the energy storage enclosure includes an outer shell and an inner shell, the outer shell and the inner shell are connected and hollow in the middle, a reinforcing frame is connected between the inner shell and the outer shell, and the mounting frame is connected to the bottom of the outer shell and the inner shell.
[0007] Preferably, a plurality of battery cabinets are installed on the mounting beam, and battery cabinet doors are connected to both sides of the energy storage chassis, with the battery cabinet doors located on both sides of the battery cabinets.
[0008] Preferably, the energy storage enclosure is connected to a controller door and a high-voltage box door on both sides, respectively. The controller door is located on one side of the cabinet controller, and the high-voltage box door is located on one side of the support beam.
[0009] Preferably, the energy storage enclosure has two auxiliary doors on one side, and the auxiliary doors, battery cabinet door, controller door, and high-voltage box door are all equipped with heat dissipation vents.
[0010] Preferably, a plurality of axial flow fans are connected to one side of the chassis frame, and the plurality of axial flow fans are arranged on one side of the two auxiliary doors.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The support structure of this application is mostly composed of rigid frames formed by bolt connections to install equipment such as battery cabinets and high-voltage boxes. It integrates a large number of components in a limited space. The modular design of the support structure can flexibly adjust the internal space layout of the energy storage box, which solves the problems of fixed internal structure, low modularity, rigid layout of functional areas and inability to adapt to multiple specifications of energy storage components in traditional energy storage boxes, resulting in unreasonable space allocation and low space utilization. It is conducive to realizing the fine allocation of internal space of energy storage box, adapting to the flexible installation of multiple specifications of energy storage components, and improving space utilization. 2. This application, through the reasonable allocation and installation of internal energy storage components, creates a continuous air channel from the air inlet to the air outlet inside the energy storage chassis. The air flows in the air channel, which can quickly remove the heat generated by the equipment. This solves the problem that batteries and electronic control components generate a lot of heat when the energy storage equipment is running, and that the traditional energy storage chassis has a messy internal layout, resulting in poor heat dissipation and low efficiency. This application helps to optimize the heat dissipation path and improve the heat dissipation efficiency of the energy storage equipment during operation. 3. This application provides two heat exchange surfaces by setting up an inner and outer double shell. At the same time, the hollow design in the sandwich layer forms a thermal resistance layer. In this way, the metal outer shell conducts heat quickly and can quickly transfer internal heat to the outside air. Meanwhile, the glass and inner plate of the inner shell conduct heat slowly, which can reduce the reverse heat transfer to the inside. This solves the problems of insufficient heat dissipation area and low heat exchange efficiency of a single shell, as well as the problems of internal heat loss in winter and external heat intrusion in summer, which affect the normal operation of energy storage equipment under wide temperature range conditions. This is conducive to ensuring the stable operation of the energy storage chassis under wide temperature range conditions. Attached Figure Description

[0014] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0015] Please see Figure 1 , Figure 2 A novel mobile energy storage power supply trailer with a double-layer heat dissipation chassis structure includes a trailer body 1 and an energy storage chassis 2 installed on the trailer body 1. The trailer body 1 relies on its own main wheels and other walking components to be towed by a tractor, moving the energy storage chassis 2 fixed on the chassis. The limiting brackets and other structures on the chassis can prevent the chassis from shifting. During the journey, the braking components can be used to brake at any time, adapting to different road conditions and smoothly reaching the working position. After reaching the appropriate position, the fixing structure can be adjusted to fix it in place, allowing the energy storage chassis 2 to work stably. The energy storage chassis 2 is internally connected to a support mechanism 8. Please see Figure 5 , Figure 6 The support mechanism 8 includes a chassis frame 9, which is installed in the energy storage chassis 2. A plurality of bottom beams 11 are connected to one side of the chassis frame 9. The bottom beams 11 are arrayed at the bottom of the chassis frame 9. Some of the bottom beams 11 support the battery cabinet, while the remaining bottom beams 11 support the high-voltage box and electrical cabinet. Fixed beams 12 are connected to both sides of the chassis frame 9. A plurality of mounting beams 13 are installed on one side of each fixed beam 12. Cabinet clips 14 are connected to the middle of the mounting beams 13. One side of the energy storage chassis 2... Several reinforcing columns 15 are connected. One side of the reinforcing column 15 is connected to the bottom beam 11 and the mounting beam 13. The fixing beam 12 is installed on the chassis frame 9. Then, the mounting beam 13 is installed between the two fixing beams 12. The mounting beam 13 consists of several layers, each layer is used to install the battery cabinet. Specifically, the battery cabinet is installed on the mounting beam 13 and fixed with the cabinet clip 14. The battery cabinet is installed by the mounting beam 13 to avoid the problem of covering one side of the battery cabinet, which is conducive to the heat dissipation of the battery cabinet. Meanwhile, several reinforcing columns 15 are connected and fixed to the mounting beams 13 at different heights, thereby reinforcing and fixing all the mounting beams 13 and ensuring the overall stability of the mounting beams 13, thus ensuring the stability of the battery cabinet after installation. It should be noted that the cabinet clip 14 is an elastic clip, so after the battery cabinet is installed, the cabinet clip 14 will be deformed by squeezing. At this time, the cabinet clip 14 resists the deformation force and cooperates with the chassis frame 9 to clamp and fix the battery cabinet. Please see Figure 7One side of the chassis frame 9 is connected to a fixed beam 16. The tops of the two bottom beams 11 are connected to support frames 17. Several support beams 18 connect between the support frames 17 and the fixed beam 16. Two support beams 18 are connected to a high-voltage box clamp 19 on one side, and the tops of the other two support beams 18 are connected to a charger mounting plate 20. The fixed beam 16 is installed on the chassis frame 9. Then, the support beams 18 are installed between the fixed beam 16 and the support frames 17. A high-voltage box is installed on one layer of support beams 18, and the high-voltage box clamp 19 is connected to the chassis frame. 9 is used to install and fix the high-voltage box. The working principle of the high-voltage box clip 19 is the same as that of the cabinet clip 14, so it will not be described again here. The function of the high-voltage box is to distribute, protect and isolate the high-voltage circuit. It is equivalent to the high-voltage power distribution center of the energy storage system. It contains high-voltage relays, fuses, contactors, busbars and other components. It is responsible for distributing the high-voltage DC power output from the battery cabinet to the charger, inverter and other equipment. It has overload protection, short circuit protection and leakage protection functions. When the circuit is abnormal, it quickly cuts off the high-voltage circuit to avoid equipment damage or safety accidents. On another set of support beams 18, a charger mounting plate 20 is installed for installing the charger. The charger is mainly responsible for the input conversion of electrical energy, replenishing the battery cabinet with electrical energy, receiving external power, and converting AC power into DC power that the battery can accept. It has constant voltage and constant current charging control functions, and automatically adjusts the charging parameters according to the battery status to avoid damaging the battery and extend the battery life.
[0016] Please see Figure 5 The top of the two bottom beams 11 is connected to the electrical cabinet fixing plate 21, and the side of the chassis frame 9 is connected to the cabinet controller 22. The cabinet controller 22 is set on one side of the electrical cabinet fixing plate 21, and the electrical cabinet is installed on the electrical cabinet fixing plate 21. The core function of the electrical cabinet is low-voltage control, power distribution and signal processing, which is equivalent to the "control and low-voltage power distribution hub" of the energy storage system. It contains low-voltage circuit breakers, relays, contactors, terminals and other components to provide stable power supply for low-voltage equipment such as cabinet controllers, sensors, and cooling fans. It integrates the wiring and interface of the control circuit to realize the signal transmission between various devices. The cabinet controller 22 is responsible for coordinating the operation of all devices, receiving instructions from the host computer, sending control signals (such as starting charging, stopping discharging, and adjusting output power) to devices such as battery cabinets, chargers, and high-voltage boxes, collecting real-time operating data of each device (such as battery status, charging and discharging power, and circuit voltage), summarizing and analyzing the data, and immediately triggering an alarm and executing protection actions (such as cutting off the circuit and stopping operation) if any abnormality is detected (such as battery overheating or circuit failure). The aforementioned fixed beam 12, mounting beam 13, fixed beam 17, support frame 17, and support beam 18 can all be adaptively installed in the energy storage enclosure 2 according to different needs. In other words, the components in the energy storage enclosure 2 can be arranged and adjusted according to needs. In this way, the modular design of the support mechanism 8 can flexibly adjust the internal space layout of the energy storage enclosure 2, solving the problems of fixed internal structure, low modularity, rigid layout of functional areas, and inability to adapt to multiple specifications of energy storage components in traditional energy storage enclosures 2, resulting in unreasonable space allocation and low space utilization. This is conducive to achieving fine allocation of internal space of the energy storage enclosure 2, flexible installation of multiple specifications of energy storage components, and improving space utilization.
[0017] Please see Figure 2 , Figure 3 , Figure 4 The bottom of the energy storage unit 2 is connected to a mounting frame 7, which is connected to one side of the trailer body 1. The energy storage unit 2 is connected and fixed to the top of the trailer body 1 through the mounting frame 7 at the bottom. The energy storage unit 2 includes an outer shell 201 and an inner shell 202. The outer shell 201 and the inner shell 202 are connected and hollow in the middle. A reinforcing frame 203 is connected between the inner shell 202 and the outer shell 201. The mounting frame 7 is connected to the bottom of the outer shell 201 and the inner shell 202. The energy storage unit 2 is provided with an inner and outer double shell, providing two heat exchange surfaces. The outer shell 201 is made of metal material, and the inner shell 202 is made of glass plate and aluminum plate structure. Together they form a double shell structure. The upper part of the inner shell 202 is mostly made of glass. When exposed to high temperatures such as sunlight, it can reflect radiation and reduce heat absorption. Specifically, glass itself has a certain thermal conductivity, which can transfer heat from high temperature areas to low temperature areas. The low coefficient of thermal expansion of glass means that the size of the glass changes little when the temperature changes, which is beneficial to maintaining the stability and heat dissipation performance of the equipment. The glass base material has a low thermal conductivity, which can effectively prevent heat transfer and air convection, weakening the role of convection in heat conduction. Glass material can reflect thermal radiation and reduce heat absorption. Glass material usually has high heat resistance and can maintain stable heat preservation performance in high temperature environments. The lower part of the inner shell 202 is made of aluminum. Aluminum has a high thermal conductivity, which can quickly transfer heat. Its thermal expansion is moderate. When the temperature changes, the size change of aluminum is relatively small, which is conducive to maintaining the stability of the structure. Aluminum has a high reflectivity, which can effectively reflect thermal radiation and reduce heat absorption in some complex high-temperature environments. Meanwhile, the hollow design within the interlayer forms a thermal resistance layer, and there is a certain space between the two shells. This space can also serve as an additional heat dissipation area. The metal outer shell 201 of the double shell conducts heat quickly, which can rapidly transfer internal heat to the outside air; while the glass and inner panel of the inner shell 202 conduct heat slowly, which can reduce the reverse transfer of heat to the inside. This solves the problems of insufficient heat dissipation area and low heat exchange efficiency of a single shell, as well as the problems of internal heat loss in winter and external heat intrusion in summer, which affect the normal operation of energy storage equipment under wide temperature range conditions. This is conducive to ensuring the stable operation of the energy storage chassis under wide temperature range conditions.
[0018] Several battery cabinets are installed on the mounting beam 13. The battery cabinet is the carrier for the integration, protection and management of battery modules. It contains multiple battery packs and is fixed by standardized brackets to achieve centralized storage of batteries. Battery cabinet doors 3 are connected to both sides of the energy storage box 2. The battery cabinet doors 3 are located on both sides of the battery cabinet.
[0019] The energy storage enclosure 2 is connected to a controller door 4 and a high-voltage box door 5 on its two sides respectively. The controller door 4 is located on one side of the cabinet controller 22, and the high-voltage box door 5 is located on one side of the support beam 18.
[0020] The energy storage enclosure 2 has two auxiliary doors 6 connected to one side. The auxiliary door 6, the battery cabinet door 3, the controller door 4, and the high voltage box door 5 are all equipped with heat dissipation vents.
[0021] Several axial flow fans 10 are connected to one side of the chassis frame 9. The axial flow fans 10 are located on one side of the two auxiliary doors 6. The operation of the axial flow fans 10 can achieve directional heat dissipation, quickly expelling the heat generated by the energy storage components inside the energy storage chassis 2, improving heat dissipation efficiency, and avoiding local overheating accumulation. With the reasonable distribution and installation of the energy storage components inside the energy storage chassis 2, a continuous air channel from the air inlet to the air outlet is formed inside the energy storage chassis. The air flows in the air channel, which can quickly remove the heat generated by the equipment. This solves the problem that the batteries and electronic control components generate a lot of heat when the energy storage equipment is running. The traditional energy storage chassis has a messy internal layout, resulting in poor heat dissipation and low efficiency. It is beneficial to optimize the heat dissipation path and improve the heat dissipation efficiency of the energy storage equipment during operation.
[0022] When using this invention: First, the trailer body 1 relies on its own main wheels and other walking components to be towed by a tractor, moving the energy storage unit 2 fixed on the frame. The limiting brackets and other structures on the frame can prevent the unit from shifting. During the journey, the braking components can brake at any time, adapting to different road conditions to reach the working position smoothly. After reaching the appropriate position, the fixing structure can be adjusted to fix it in place, allowing the energy storage unit 2 to work stably. Secondly, the fixed beam 12 is installed on the chassis frame 9, and then the mounting beam 13 is installed between the two fixed beams 12. The mounting beam 13 consists of several layers, each layer for installing the battery cabinet. Specifically, the battery cabinet is installed on the mounting beam 13 and fixed with the cabinet clip 14. The battery cabinet is installed by the mounting beam 13 to avoid the problem of covering one side of the battery cabinet, which is conducive to the heat dissipation of the battery cabinet. Several reinforcing columns 15 are connected and fixed to the mounting beams 13 at different heights, thereby strengthening and fixing all the mounting beams 13 and ensuring the overall stability of the mounting beams 13. This ensures the stability of the battery cabinet after installation. The cabinet clip 14 is an elastic clip, so the cabinet clip 14 will deform after the battery cabinet is installed. At this time, the cabinet clip 14 resists the deformation force and cooperates with the chassis frame 9 to clamp and fix the battery cabinet. Then, the second fixed beam 16 is installed on the chassis frame 9, and the support beam 18 is then installed between the second fixed beam 16 and the support frame 17. The high-voltage box is installed on one of the support beams 18, and the high-voltage box clip 19 cooperates with the chassis frame 9 to install and fix the high-voltage box. The working principle of the high-voltage box clip 19 is the same as that of the cabinet clip 14. The charger mounting plate 20 is installed on another set of support beams 18 for installing the charger. The aforementioned first fixed beam 12, mounting beam 13, second fixed beam 17, support frame 17, support beam 18, etc. can all be adaptively adjusted and installed in the energy storage chassis 2 according to different needs. That is to say, the components in the energy storage chassis 2 can be arranged and adjusted according to needs. In this way, the modular design of the support mechanism 8 can flexibly adjust the internal space layout of the energy storage chassis 2, solving the problems of fixed internal structure, low modularity, rigid layout of functional areas, and inability to adapt to multiple specifications of energy storage components in traditional energy storage chassis 2, resulting in unreasonable space allocation and low space utilization. Finally, the energy storage enclosure 2 features a double-layer shell, providing two heat exchange surfaces. The outer shell 201 is made of metal, while the inner shell 202 is composed of glass and aluminum plates, forming the double-shell structure. The upper part of the inner shell 202 is mostly made of glass, which can reflect radiation and reduce heat absorption in high-temperature environments such as direct sunlight. Specifically, glass itself has a certain thermal conductivity, allowing heat to be transferred from high-temperature areas to low-temperature areas. Glass has a low coefficient of thermal expansion, meaning that its dimensions change little with temperature variations, which helps maintain equipment stability and heat dissipation performance. The low thermal conductivity of the glass substrate effectively prevents heat transfer and air convection, weakening the role of convection in heat conduction. Glass can reflect thermal radiation, reducing heat absorption. Furthermore, glass typically has high heat resistance, maintaining stability in high-temperature environments. Thermal insulation performance: The lower part of the inner shell 202 is made of aluminum, which has a high thermal conductivity and can quickly transfer heat. Its thermal expansion is moderate, and the size change of aluminum is relatively small when the temperature changes, which is conducive to maintaining the stability of the structure. Aluminum has a high reflectivity, which can effectively reflect heat radiation and reduce heat absorption in some complex high-temperature environments. The hollow design in the sandwich layer forms a thermal resistance layer. There is a certain space between the two shells, which can also serve as an additional heat dissipation area. The metal outer shell 201 of the double shell has fast thermal conductivity and can quickly transfer internal heat to the outside air. The glass and inner panel of the inner shell 202 have slow thermal conductivity, which can reduce the reverse heat transfer to the inside. This solves the problems of insufficient heat dissipation area and low heat exchange efficiency of a single shell, as well as internal heat loss in winter and external heat intrusion in summer, which affect the normal operation of energy storage equipment under wide temperature range conditions. This is conducive to ensuring the stable operation of the energy storage chassis under wide temperature range conditions.
