Description

Technical Field

[0001] This utility model relates to the field of battery box technology, and in particular to an air-cooled battery box. Background Technology

[0002] An air-cooled battery box is an integrated enclosure structure designed specifically for power battery packs in energy storage systems. Its core function is to regulate the temperature of the power batteries inside the box through airflow, ensuring that the batteries are always in a safe and efficient operating temperature range during charging and discharging. At the same time, it provides basic protection for the batteries through physical protection, electrical insulation, and sealing and dust prevention.

[0003] A search revealed Chinese patent publication number CN220710405U, which discloses an air-cooled battery box, including a box body and a battery module. The battery module is disposed in the receiving cavity of the box body and includes multiple battery cells. The multiple battery cells are arranged at intervals along a first direction. A first cooling channel is formed between two adjacent battery cells in the battery module. Multiple first through holes are provided on the box body, and each first through hole is directly opposite to each first cooling channel. A wind guide is provided in the receiving cavity corresponding to each first cooling channel. A third cooling channel is provided in the wind guide. One end of the third cooling channel is connected to the first cooling channel, and the other end of the third cooling channel is connected to the second cooling channel and faces the second through hole. By setting up air guides, with the outlet of the third cooling channel inside the air guides facing the second through hole, the flow direction of the cooling air flowing out of the first cooling channel can be made consistent with the original flow direction of the cooling air in the second cooling channel, reducing the number of times the cooling air direction changes. However, air-cooled battery boxes are mostly front-panel exhaust type; hot air directed at the human body poses a safety hazard, and the internal air ducts are mostly made of additional parts, with complex structures. Their air ducts are mostly honeycomb or matrix-type dense small holes, which are more complicated to process and have limited air intake. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an air-cooled battery box, which aims to improve the problems of complex structure, low efficiency, limited air intake, and inability to quickly inspect and repair existing battery boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an air-cooled battery box, including a box body, a box cover provided on the top of the box body, a box panel installed on the right side of the outer wall of the box body, a battery module installed inside the box body, a cooling mechanism installed inside the box body, the cooling mechanism being used to quickly dissipate heat from the battery module, and a fixing mechanism provided on the outer wall of the box body, the fixing mechanism being used to quickly fix the box cover to the box body; The cooling mechanism includes a bracket, which is fixedly connected to the right side of the inner wall of the enclosure. A BMS module is installed on the right side of the outer wall of the bracket. A connector is installed on the right side of the outer wall of the enclosure cover. A cooling assembly is installed inside the enclosure.

[0006] As a further description of the above technical solution: The cooling assembly includes a fan, which is fixedly connected to the left side of the outer wall of the housing. An air guide shroud is fixedly connected to the left side of the inner wall of the housing. An air duct is installed on the top wall of the air guide shroud. Air inlets are provided on both the front and rear sides of the outer wall of the housing.

[0007] As a further description of the above technical solution: The fixing mechanism includes a positioning block, which is fixedly connected to the bottom wall of the box cover. The positioning block engages with a positioning groove. The top wall of the box body has a positioning groove, and the outer wall of the box body is provided with a fixing component.

[0008] As a further description of the above technical solution: The fixing component includes a fixing block, which is fixedly connected to the outer wall of the housing. A pin passes through the outer wall of the fixing block, and a slide rod is fixedly connected to the outer wall of the pin. An L-shaped groove is formed on the outer wall of the fixing block, and the L-shaped groove is slidably connected to the slide rod. A spring is provided on the outer wall of the pin. Multiple circular grooves are formed at equal intervals on the outer wall of the positioning block, and the circular grooves engage with the pin.

[0009] As a further description of the above technical solution: The air duct is located inside the battery module, and the top of the air duct has a flat top design.

[0010] As a further description of the above technical solution: The spring is located inside the fixing block, which is equidistantly distributed on the upper part of the outer wall of the box.

[0011] As a further description of the above technical solution: The outer wall of the box is provided with hanging ears on the right side of the front and rear sides. Multiple bolts are threadedly connected to the outside of the hanging ears at equal intervals, and the bolts are threadedly connected to the box.

[0012] As a further description of the above technical solution: Connecting blocks are fixedly connected to the front and rear ends of the right side of the outer wall of the chassis panel, and handles are rotatably connected to the inner side of the connecting blocks.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the BMS module monitors the temperature in real time. If the temperature inside the box reaches the heat dissipation threshold, the fan is activated. The fan creates negative pressure inside the box, allowing external cold air to enter through the air inlets with large openings on the front and rear sides of the outer wall of the box. This not only effectively draws in air but also reduces the weight of the box. The air guide hood inside the box works in conjunction with the air duct to guide and direct the hot air, improving heat dissipation efficiency. The top of the air duct is designed as a flat surface, forming a 2mm gap with the bottom of the box cover. When the box cover is placed on the box, this gap contacts the edge of the box, which can limit the box cover and prevent it from being squeezed and dented. The connector on the right side of the box cover provides electrical connection support for each component. The air outlet of the box is at the rear, forming a channel to guide the air into the box from the center, without the need for additional parts.

[0014] 2. In this utility model, the positioning block of the lid is aligned and engaged with the positioning groove of the box body to initially position the lid. At this time, the spring inside the fixing block pushes the pin into the round groove of the positioning block to complete the fixing of the lid and the box body. When the lid needs to be opened, the pin is pulled to drive the slide rod to slide in the L-shaped slide groove of the fixing block. The pin compresses the spring and exits the round groove. The slide rod is rotated to the horizontal section of the L-shaped slide groove and kept in the unlocked state to remove the lid. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figure 2 , Figure 3 and Figure 4 The present invention provides an embodiment of an air-cooled battery box, comprising a box body 1, a box cover 2 on the top of the box body 1, a box panel 3 installed on the right side of the outer wall of the box body 1, a battery module 4 installed inside the box body 1, a cooling mechanism 5 installed inside the box body 1, the cooling mechanism 5 being used to quickly dissipate heat from the battery module 4, and a fixing mechanism 6 being provided on the outer wall of the box body 1, the fixing mechanism 6 being used to quickly fix the box cover 2 onto the box body 1; The cooling mechanism 5 includes a bracket 501, which is fixedly connected to the right side of the inner wall of the housing 1. A BMS module 502 is installed on the right side of the outer wall of the bracket 501. A connector 503 is installed on the right side of the outer wall of the housing cover 2. A cooling assembly 504 is installed inside the housing 1. The cooling assembly 504 includes a fan 5041, which is fixedly connected to the left side of the outer wall of the housing 1. An air guide shroud 5042 is fixedly connected to the left side of the inner wall of the housing 1. An air duct 5043 is installed on the top wall of the air guide shroud 5042. Air inlets 5044 are provided on both the front and rear sides of the outer wall of the housing 1. The air duct 5043 is located inside the battery module 4. The top of the air duct 5043 adopts an upper flat design. Specifically, the BMS module 502 monitors temperature changes in real time. If the internal temperature of the enclosure 1 reaches the heat dissipation threshold, the fan 5041 is activated. The fan 5041 creates a negative pressure environment inside the enclosure 1, causing external cold air to flow in through the air inlets 5044 on the front and rear sides of the outer wall of the enclosure 1. The air inlets 5044 feature a large-area opening design, which not only effectively guides airflow into the enclosure 1 but also significantly reduces the weight of the enclosure 1. The hot air is guided and diverted through a combination of the air guide shroud 5042 and the air exhaust shroud 5043 inside the enclosure 1. To improve heat dissipation efficiency, the top of the air hood 5043 is designed as a flat surface, and a 2mm gap is formed between the air hood 5043 and the bottom of the cover 2. When the cover 2 is placed on the box body 1, this gap contacts the edge of the box body 1, which can limit the cover 2 and prevent it from being squeezed and dented downwards. The connector 503 on the right side of the cover 2 provides electrical connection support for each component. The air outlet of the box body 1 is located at the rear of the box body 1, forming a channel that can guide air into the box from the center position. This function can be achieved without adding any additional parts.

[0019] Reference Figure 2 , Figure 3 and Figure 5 The fixing mechanism 6 includes a positioning block 601, which is fixedly connected to the bottom wall of the box cover 2. The positioning block 601 engages with the positioning groove 602. The top wall of the box body 1 is provided with the positioning groove 602, and the outer wall of the box body 1 is provided with a fixing component 603. The fixing component 603 includes a fixing block 6031, which is fixedly connected to the outer wall of the housing 1. A pin 6032 passes through the outer wall of the fixing block 6031. A slide rod 6033 is fixedly connected to the outer wall of the pin 6032. An L-shaped groove 6034 is opened on the outer wall of the fixing block 6031. The L-shaped groove 6034 is slidably connected to the slide rod 6033. A spring 6035 is provided on the outer wall of the pin 6032. A plurality of circular grooves 6036 are equidistantly opened on the outer wall of the positioning block 601. The circular grooves 6036 engage with the pin 6032. The spring 6035 is located inside the fixing block 6031. The fixing blocks 6031 are equidistantly distributed in the upper middle part of the outer wall of the housing 1. Specifically, the positioning block 601 of the lid 2 is aligned and engaged with the positioning groove 602 of the body 1 to achieve initial positioning of the lid 2. At this time, the spring 6035 in the fixing block 6031 pushes the pin 6032, causing the pin 6032 to insert into the circular groove 6036 of the positioning block 601, thereby completing the fixing of the lid 2 and the body 1. If it is necessary to open the lid 2, pull the pin 6032, and at the same time drive the slide rod 6033 on the pin 6032 to slide in the L-shaped slide groove 6034 on the fixing block 6031. The pin 6032 compresses the spring 6035 and exits from the circular groove 6036. Rotating the slide rod 6033 to the horizontal section of the L-shaped slide groove 6034 will keep it in the unlocked state, and the lid 2 can be removed at this time.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The outer wall of the housing 1 is provided with a hanging ear 7 on the right side of the front and rear sides. Multiple bolts 8 are threadedly connected to the outside of the hanging ear 7 at equal intervals. The bolts 8 are threadedly connected to the housing 1. The front and rear ends of the right side of the outer wall of the chassis panel 3 are fixedly connected with a connecting block 9. The inner side of the connecting block 9 is rotatably connected with a handle 10. Specifically, the hanging ear 7 is used to provide an external mounting support point for the box 1, the bolt 8 is used to firmly fix the hanging ear 7 to the outer wall of the box 1, and the connecting block 9 is used to install the handle 10, which is used to facilitate the movement of the box 1.

[0021] Working principle: The BMS module 502 monitors temperature changes in real time. If the temperature inside the enclosure 1 reaches the heat dissipation threshold, the fan 5041 is activated. The fan 5041 creates negative pressure inside the enclosure 1, allowing external cool air to enter through the air inlets 5044 on the front and rear sides of the outer wall of the enclosure 1. The air inlets 5044 have large openings, which can fully guide the air into the enclosure 1 and greatly reduce the weight of the enclosure 1. The hot air is guided and diverted by the combined action of the air guide shroud 5042 and the air exhaust shroud 5043 inside the enclosure 1, thereby increasing heat dissipation. Efficiency is achieved because the top of the air hood 5043 is designed as a flat surface, thus forming a 2mm gap between the air hood 5043 and the bottom of the cover 2. When the cover 2 is placed on the box body 1, this gap contacts the side of the box body 1, which can limit the cover 2 and prevent it from being squeezed and dented downwards. The connector 503 on the right side of the cover 2 provides electrical connection support for each component. The air outlet of the box body 1 is located at the rear of the box body 1, forming a channel that can guide the air from the center position into the box. This action can be completed without additional parts. Align and engage the positioning block 601 of the lid 2 with the positioning groove 602 of the body 1 to achieve initial positioning of the lid 2. At this time, the spring 6035 in the fixing block 6031 pushes the pin 6032, causing the pin 6032 to insert into the circular groove 6036 of the positioning block 601, thus fixing the lid 2 to the body 1. When the lid 2 needs to be opened, pull the pin 6032, which simultaneously causes the slide rod 6033 on it to slide in the L-shaped slide groove 6034 on the fixing block 6031. The pin 6032 compresses the spring 6035 and exits from the circular groove 6036. Rotate the slide rod 6033 to the horizontal section of the L-shaped slide groove 6034 to maintain the unlocked state. At this time, the lid 2 can be removed.
