A wind guide frame is bolted to the inner wall of the chassis. A set of fans is installed on one side of the wind guide frame along its length, and a terminal block is installed on the other side. This energy storage device with a wind-guiding and heat dissipation mechanism, through the fan and air inlet slot, can extract heat from inside the chassis after the fan is started, and allow outside air to enter the chassis through a gap on the side opposite to the fan.

Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, specifically to an energy storage device with a wind-guiding and heat dissipation mechanism. Background Technology

[0002] Energy storage equipment refers to a class of devices or systems that can realize the functions of energy storage and release. It plays a key role in the process of energy conversion, storage and utilization. Energy storage equipment is like an "energy warehouse" that can store excess energy when there is a surplus of energy and release the stored energy when energy demand increases or supply is insufficient, so as to meet different energy needs and balance the differences between energy supply and demand in time and space.

[0003] An existing patent (publication number: CN222319409U) discloses an air-cooled energy storage chassis, belonging to the field of chassis technology. It includes a main body module and a disassembly / assembly module. The main body module includes a rear baffle, with side baffles at both ends. The disassembly / assembly module is located between the two side baffles and includes a cover plate assembly located between the two side baffles. A front baffle assembly is located between one end of the two side baffles, and locking components are provided between the front baffle assembly and the two side baffles. This application facilitates the disassembly and assembly of the top and bottom plates of the chassis through the cover plate assembly, the disassembly and assembly of the front plate assembly, and the locking components for locking the front plate, thereby facilitating maintenance and extending the service life of the chassis.

[0004] During use, the two air channels of the aforementioned energy storage chassis are located at the top and side of the chassis, respectively. However, during use, the internal heat dissipation relies solely on the natural flow of air. The natural airflow is slow and unstable, and cannot form a sufficiently strong and stable airflow to quickly remove the heat generated by the energy storage components. The accumulation of heat will affect the service life of the energy storage components inside the chassis. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an energy storage device with a wind-guiding and heat dissipation mechanism, which has advantages such as dustproof and waterproof properties and improved heat dissipation, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy storage device with a wind-guiding and heat dissipation mechanism, comprising a chassis, the chassis comprising an L-shaped side frame, the side frame being fixedly installed on the inner wall of the chassis, a wind guide frame being fixedly installed on the inner wall of the chassis by bolts, a set of fans being fixedly installed inside the side frame, a terminal block being installed on the other side of the wind guide frame, multiple irregularly distributed air inlet slots being opened on the side of the wind guide frame, notches being opened on both sides of the chassis along its length direction, an inverter body being arranged inside the chassis, a sliding groove being opened on the side of the side frame, an insertion hole being opened on the inner top wall of the wind guide frame, a spring pin being fixedly installed on the inner wall of the side frame, the spring pin being L-shaped, and the bottom end of the spring pin being slidably connected to the sliding groove, and the top end of the spring pin being inserted into the insertion hole;

[0007] Both notches are equipped with air duct covers, and both notches are equipped with quick-release mechanisms for removing the air duct covers. The quick-release mechanisms include dustproof components.

[0008] Furthermore, the quick-release mechanism includes two insert plates fixedly connected to the upper end of the duct cover plate, a fixed frame fixedly connected to the inner wall of the duct cover plate, a sliding groove corresponding to the position of the insert plates formed on the upper surface of the fixed frame, a pin seat installed on the side of the duct cover plate by bolts, a positioning pin slidably connected inside the pin seat, one end of the positioning pin contacting the fixed frame, a sliding groove is opened on the side of the duct cover plate, and the positioning pin is slidably connected along the inner wall of the sliding groove.

[0009] The above solution allows for the initial positioning and installation of one end of the duct cover through the cooperation of the insert plate and the slide groove. The positioning pin slides in the insert pin seat and contacts the fixed frame, which can further fix the other end of the duct cover. The duct cover can be disassembled by sliding the positioning pin. The operation is simple and quick, and it is convenient for maintenance and repair of the wiring harness.

[0010] Furthermore, the quick-release mechanism also includes a set of self-locking slide rails installed between the air guide frame and the side frame, and the inverter body is fixedly installed on the air guide frame by bolts.

[0011] The above solution ensures that the inverter body automatically locks after installation, preventing displacement due to vibration or other factors during operation. Furthermore, when inspecting the inverter body inside the chassis, only the duct cover, terminal block, and wiring harness on the inverter body need to be removed. The inverter body can then be quickly pulled out from the notch by unlocking the self-locking rail, facilitating convenient and quick maintenance.

[0012] Furthermore, the dustproof component includes two baffles fixedly connected to the side of the air duct cover inside the chassis, with a dustproof net inserted between the two baffles. Both ends of the chassis surface along the vertical direction are provided with cable inlets, and the inner walls of the two cable inlets are fitted with cable tie silicone sleeves. Side plates are fixedly connected to the side of the chassis by bolts.

[0013] The above solution, through the dustproof components, can prevent external dust from entering the inverter body inside the chassis while it is operating, by using dustproof mesh, cable tie silicone sleeves, and side panels to block the dust and avoid dust entering the chassis and affecting the inverter body inside the chassis.

[0014] Furthermore, the side of the air duct cover is designed with a hollowed-out shape.

[0015] The above solution involves a perforated design on the side of the air duct cover, which can increase the airflow area and improve the ventilation and heat dissipation effect while ensuring the structural strength of the chassis. It also helps to reduce the weight of the air duct cover.

[0016] Furthermore, the dustproof net is made of aluminum alloy mesh.

[0017] Through the above solution, the aluminum alloy mesh can effectively intercept extremely small dust particles while ensuring smooth airflow. It also has anti-oxidation and corrosion resistance properties, enabling it to work stably for a long time without deformation or rusting in the complex environment in which the inverter body is located.

[0018] Furthermore, the chassis, side panels, and air duct cover are all made of metal.

[0019] The above solution utilizes the excellent thermal conductivity and structural strength of metal materials, which on the one hand helps to conduct and dissipate heat inside the chassis, improving the heat dissipation effect; on the other hand, it can ensure the stability of the overall chassis structure and extend the service life of the equipment.

[0020] Furthermore, a control panel is fixedly installed on one side of the chassis, and the control panel includes indicator lights that display the power level.

[0021] The above scheme enables the control panel to control the switching of charging and discharging modes, the adjustment of output power, and the display of fault codes of the energy storage device. The indicator lights can display the remaining power percentage and charging status in real time through different color combinations.

[0022] Furthermore, the chassis also includes multiple lift-type casters arranged in a matrix and fixedly installed at the bottom.

[0023] The above solution, with multiple lift-type casters, allows for the movement or stable placement of the chassis according to user needs, improving overall convenience.

[0024] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0025] This energy storage device with a wind-guiding and heat dissipation mechanism, through the setting of a fan and air inlet slot, can extract heat from inside the chassis after the fan is started, and allow outside air to enter the chassis from the opening on the side opposite to the fan. Due to the setting of the terminal block, the air entering the chassis will first contact the terminal block, thereby cooling the terminal block first. Subsequently, the airflow will contact the inverter body inside the chassis through the air inlet slot, thereby dissipating heat from the inverter body. The heat is discharged from the opening near the fan, thereby improving the heat dissipation effect on the internal components of the chassis.

[0026] The quick-release structure allows the duct cover to slide after the locating pin is slid along the sliding groove and the spring pin is released. The duct cover can then be pulled out to complete the disassembly. After disassembly, the self-locking slide rail is engaged, allowing the inverter body to be pulled out from the notch along the self-locking slide rail. This facilitates the maintenance of the inverter body and is convenient and quick. Attached Figure Description

[0044] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] Please see Figures 1-8This embodiment of an energy storage device with a wind-guiding and heat dissipation mechanism includes a chassis 1. The chassis 1 includes an L-shaped side frame 101, which is fixedly installed on the inner wall of the chassis. A wind guide frame 2 is fixedly installed on the inner wall of the chassis 1 by bolts. A set of fans 3 is fixedly installed inside the side frame 101. A terminal block 4 is installed on the other side of the wind guide frame 2. Multiple irregularly distributed air inlet slots 5 are opened on the side of the wind guide frame 2. Notches 6 are opened on both sides of the chassis 1 along its length. Through the fans 3 and the air inlet slots 5, the heat inside the chassis 1 can be extracted after the fans 3 are started, and the outside air can enter the chassis 1 through the notch 6 on the side opposite to the fans 3. Due to the position of the terminal block 4, the air entering the chassis 1 will first contact the terminal block 4, thus first contacting the terminal block 4. Cooling is achieved by airflow through the air inlet slot 5 to contact the energy storage components inside the chassis 1, thereby dissipating heat from the energy storage components. The heat is discharged from the notch 6 near the fan 3, thus improving the heat dissipation effect on the energy storage components inside the chassis 1. The inverter body 9 is installed inside the chassis 1. The side frame 101 has a sliding groove 10 on its side. The inner top wall of the air guide frame 2 has an insertion hole 11. A spring pin 12 is fixedly installed on the inner wall of the side frame 101. The spring pin 12 is L-shaped, and the bottom end of the spring pin 12 is slidably connected to the sliding groove 10. The top end of the spring pin 12 is inserted into the insertion hole 11. The elastic pin 12 can be inserted into the insertion hole 11 by the deformation force of the spring to limit the air guide frame 2, so that the air guide frame 2 can maintain a stable connection with the side frame 101.

[0046] Both notches 6 have duct covers 7 inside, and both notches 6 have quick-release mechanisms 8 for removing the duct covers 7. The quick-release mechanism 8 includes a dustproof component 801. By setting the quick-release mechanism 8, the duct covers 7 can be quickly removed, which is convenient for maintenance of the terminal block 4. In actual use, the connection between the inverter body 9 and the BMS protection board communication interface (not marked in the figure) in the equipment is exposed, which is convenient for maintenance of the communication line and related components.

[0047] The quick-release mechanism 8 includes two insert plates 802 fixedly connected to the upper end of the duct cover 7. A fixed frame 803 is fixedly connected to the inner wall of the chassis 1. The upper surface of the fixed frame 803 has a sliding groove 804 corresponding to the position of the insert plates 802. A pin seat 805 is bolted to the side of the duct cover 7. A positioning pin 806 is slidably connected inside the pin seat 805. One end of the positioning pin 806 contacts the fixed frame 803. A sliding groove 807 is opened on the side of the duct cover 7. The positioning pin 806 is slidably connected along the inner wall of the sliding groove 807. Through the cooperation of the insert plates 802 and the sliding groove 804, one end of the duct cover 7 can be initially positioned and installed. The positioning pin 806 slides in the pin seat 805 and contacts the fixed frame 803, which can further fix the other end of the duct cover 7. The duct cover 7 can be disassembled by sliding the positioning pin 806. The operation is simple and quick, and it is convenient for maintenance and repair of the terminal block 4.

[0048] The quick-release mechanism 8 also includes a set of self-locking slide rails 808 installed between the air guide frame 2 and the side frame. The inverter body 9 is fixedly installed on the air guide frame 2 by bolts. The self-locking slide rails 808 can ensure that the inverter body 9 is automatically locked after installation, preventing it from shifting due to vibration or other factors during operation. At the same time, when inspecting the inverter body 9 inside the chassis 1, it is only necessary to remove the air duct cover 7, the terminal block 4, and the wiring harness on the inverter body 9. The inverter body 9 can be quickly pulled out from the notch 6 by unlocking the self-locking slide rails 808, which is convenient and quick for maintenance of the inverter body 9.

[0049] The dustproof component 801 includes a duct cover 7 and two baffles 8011 fixedly connected to the side of the chassis 1. A dustproof mesh 8012 is inserted between the two baffles 8011. Cable inlets 8013 are provided at both ends of the chassis 1 along the vertical direction. Cable bundle silicone sleeves 8014 are installed on the inner walls of both cable inlets 8013. By placing the cable inlets 8013 on one side of the top of the chassis 1, it is easier to route cables along the wall inside the chassis 1 when it is flush with the wall, allowing for a more organized cable layout and preventing cables from interfering with users. Side plates 8015 are fixedly connected to the side of the chassis 1 by bolts. The dustproof component 801, when the inverter body 9 is working inside the chassis 1, prevents external dust from entering the chassis 1 through the interception of the dustproof net 8012, the cable tie silicone sleeve 8014, and the side plate 8015. This avoids dust entering the chassis 1 and affecting the inverter body 9 inside the chassis 1. The dustproof net 8012 is made of aluminum alloy mesh. The aluminum alloy mesh can effectively intercept extremely small dust particles while ensuring smooth airflow. It also has anti-oxidation and corrosion resistance properties, so it can work stably for a long time without deformation or rusting under the complex environmental conditions where the inverter body is located.

[0050] The chassis 1, side panel 8015, and air duct cover 7 are all made of metal. Metal has good thermal conductivity and structural strength, which helps to conduct and dissipate heat inside the chassis 1, improving the heat dissipation effect. On the other hand, it can ensure the overall structural stability of the chassis 1 and extend the service life of the equipment. The side of the air duct cover 7 has a hollow design, which can increase the air circulation area while ensuring the structural strength of the chassis 1, improving the ventilation and heat dissipation effect, and also helps to reduce the weight of the air duct cover 7.

[0051] A control panel 13 is fixedly installed on one side of the chassis 1. The control panel includes an indicator light 1301 that displays the power level. The control panel 13 can control the switching of charging and discharging modes, the adjustment of output power, and the display of fault codes of the energy storage device. The indicator light 1301 can display the remaining power percentage and charging status in real time through different color combinations. The chassis 1 also includes multiple liftable casters 102 fixedly installed at the bottom in a matrix arrangement. The multiple liftable casters 102 can move or stably place the chassis 1 according to user needs, improving the overall convenience.

[0052] It should be noted that the self-locking slide rail 808 is a sliding rail device with an automatic locking function. Its core feature is that when the slide rail moves to a specific position, such as fully extended or closed, it can automatically lock through a mechanical structure or elastic element, maintaining stability without additional manual operation. To unlock the self-locking slide rail, it is usually necessary to select the corresponding method according to its design type. Common operations include pressing, pulling, and sliding the corresponding parts on the self-locking slide rail to unlock it.

[0053] The working principle of the above embodiment is as follows: First, when the fan 3 is turned on, the fan 3 draws out the air inside the chassis 1 and discharges it through the gap 6 adjacent to the fan 3. Meanwhile, the outside air enters the chassis 1 through the gap 6 on the other side. The air entering the chassis 1 will first come into contact with the terminal block 4 to dissipate heat at the terminal block 4. Then, the air passes through the air inlet slot 5 to form an airflow, which dissipates heat from the energy storage components inside the chassis 1, creating a convection effect inside the chassis 1 and improving the heat dissipation effect on the energy storage components inside the chassis 1.

[0054] When maintenance is required on the energy storage components inside the chassis 1, slide the positioning pin 806 along the sliding groove 807 to separate the positioning pin 806 from the fixed frame 803. Then, slide the duct cover 7 in the direction of the positioning pin 806 to make the insert plate 802 slide in the sliding groove 804. Then, slide the spring pin 12 on the other side to release the limit on the air guide frame 2. Then, pull out the air duct cover 7 to complete the disassembly of the air duct cover 7. After the air duct cover 7 is disassembled, by releasing the lock of the self-locking slide rail 808, the air guide frame 2 can be pulled out from the notch 6 along the self-locking slide rail 808, which increases the space for maintenance of the inverter body 9 and improves the convenience of maintenance of the inverter body 9 for users.

[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0056] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
