Description

Technical Field

[0001] This invention relates to a sealed, dustproof, directional heat dissipation battery compartment, which is a battery energy storage device that combines sealing and dustproofing with directional heat dissipation. It belongs to the field of heat dissipation and dustproofing technology for battery energy storage devices. Specifically, it relates to a sealed, dustproof, and uniformly diffused airflow achieved through a sealed air intake structure and a gradually expanding spiral air outlet in the heat dissipation component; and a rack and pinion linkage in the reversing component drives the vent pipe to rotate synchronously to adjust the airflow direction; ultimately achieving precise directional heat dissipation, compatibility with existing battery compartment layouts, and reduced application costs. Background Technology

[0002] Current mainstream battery compartment heat dissipation and dust prevention technologies primarily employ a combination of passive dust prevention via filters / louvers and fixed-direction ventilation. This involves creating ventilation openings on the side walls of the battery compartment, using filters or louvers to block large dust particles, and simultaneously utilizing a fan to drive airflow in a fixed direction across the surface of the battery modules to achieve heat dissipation. This mainstream technology suffers from two significant drawbacks: First, it's difficult to simultaneously achieve dust prevention and heat dissipation. Filters or louvers cannot completely block fine dust particles, and over time, dust accumulates at the ventilation openings and on the battery module surfaces, leading to decreased heat dissipation efficiency and potential insulation problems. Furthermore, filters require regular removal and replacement, resulting in high maintenance costs. Second, the precision and adaptability of heat dissipation are poor. The fixed-direction ventilation structure cannot adjust the airflow direction according to temperature differences in different areas of the battery compartment, easily leading to insufficient heat dissipation in locally hot areas. Additionally, adapting to this structure requires a specific design for the overall battery compartment layout, making it difficult to directly integrate with existing mass production processes for different battery compartment specifications.

[0003] CN117352897A discloses a battery compartment heat dissipation structure, including a protective shell. Inside the protective shell is a power supply unit. Multiple sets of heat dissipation fins are fixedly installed on the lower inner surface of the protective shell. The power supply unit is positioned above the heat dissipation fins. Ventilation grilles are provided on the left and right sides of the front face of the protective shell. A water-cooling mechanism is located inside the protective shell. An opening and closing mechanism is located on the front side of the protective shell. A one-way drive mechanism is provided between the opening and closing mechanism and the water-cooling mechanism, causing the motor's output shaft to rotate in reverse, carrying a ratchet pawl. Racket pawl 1 and ratchet pawl 2 engage with each other, driving a gear ring to rotate. The gear meshes with a gear on a worm, driving the worm. The worm gear is driven, and the worm wheel meshes with the worm, causing the worm wheel to rotate. The worm wheel then meshes with a rack on a baffle, causing the baffle to rise and connect the ventilation vents to the ventilation grilles, thus ventilating the air inside the protective shell. However, although the above structure uses a ventilation grille combined with a baffle, it cannot prevent dust from entering at the source. The dustproof effect depends on the sealing of the baffle. In high dust environments, dust can still easily seep in. Summary of the Invention

[0004] To improve the above situation, the present invention provides a sealed dustproof directional heat dissipation battery compartment. This compartment achieves both dustproof sealing and uniform airflow diffusion through a sealed air intake structure and a gradually expanding spiral air outlet of the heat dissipation component. The rack and pinion linkage of the reversing component drives the vent pipe to rotate synchronously and adjust the airflow direction. Ultimately, this sealed dustproof directional heat dissipation battery compartment achieves precise directional heat dissipation, is compatible with existing battery compartment layouts, and reduces application costs.

[0010] The sealed, dustproof, directional heat dissipation battery compartment of the present invention is implemented as follows: The sealed, dustproof, directional heat dissipation battery compartment of the present invention includes a battery compartment (1), a heat dissipation assembly, and a reversing assembly. Its characteristic is that the heat dissipation assembly is provided in multiple sets, and all sets of heat dissipation assemblies rotate synchronously through a redirection assembly. Each heat dissipation assembly includes a battery compartment (1), a connecting slot (3), a vent pipe (4), an air inlet pipe (2), a diffuser block (10), an air outlet (9), and a transmission gear (8). The battery compartment (1) has a hollow structure and contains multiple battery modules. Preferably, the air vent of the battery compartment (1) is located at the top or side near the top. The battery compartment (1) has a connection slot (3) on one side. Preferably, NTC temperature sensors are evenly distributed between the battery modules and the side walls of the battery compartment (1). The plurality of connecting slots (3) are arranged at equal intervals in the vertical direction. The vent pipe (4) is fitted into the connecting groove (3), and both ends are rotatably connected to the side wall of the battery compartment (1) via a rotating shaft. The connecting groove (3) matches the shape of the vent pipe (4), and the vent pipe (4) has a hollow internal structure. Preferably, a silicone sealing ring is provided on the contact surface between the connecting groove (3) and the vent pipe (4). One end of the air intake pipe (2) passes through the side adjacent to the side with the connecting groove (3) and one end of the air vent pipe (4), and communicates with the inside of the air vent pipe (4). The diffuser block (10) is placed inside the battery compartment (1) and is fixedly connected to the vent pipe (4). The diffuser block (10) has multiple air inlets (9) arranged equidistantly along the axial direction of the vent pipe (4), and the hollow structure inside the vent pipe (4) communicates with the interior of the battery compartment (1) through the air inlets (9). Preferably, the cross-sectional diameter of the air inlet (9) gradually increases from one end of the hollow structure of the air pipe (4) to the other end. Preferably, the sidewall of the air inlet (9) is provided with spiral guide lines. The transmission gear (8) and the air intake pipe (2) are respectively placed on two opposite sides of the battery compartment (1). The axle of the transmission gear (8) passes through this side and is fixedly connected to the other end of the air vent pipe (4), and is rotatably connected to the battery compartment (1). The reversing assembly includes a support frame (5), a rack (7), and a telescopic rod (6). The support frame (5) is fixedly connected to one side of the battery compartment (1), and it and the transmission gear (8) are located on the same side of the battery compartment (1). Preferably, the support frame (5) has a U-shaped structure, consisting of a vertical plate and two horizontal plates, and the vertical plate of the support frame (5) has a sliding groove. The rack (7) is slidably connected to the support frame (5) via a sliding groove and meshes with the transmission gear (8). One end of the telescopic rod (6) is fixedly connected to the horizontal plate of the support frame (5), and the other end is fixedly connected to the straight rack (7). In use, the air inlet pipes (2) of multiple heat dissipation components are first connected to the same main air inlet pipe. After the external clean gas is diverted through the main air inlet pipe, it enters the hollow structure inside the corresponding vent pipe (4) through each air inlet pipe (2). The gas is conducted to the diffuser block (10) in the vent pipe (4) and is ejected through the air outlets (9) on the diffuser block (10) that are equidistant along the axial direction of the vent pipe (4) and have gradually expanding cross-sectional diameters. The spiral guide pattern on the side wall of the air outlet (9) makes the airflow form a rotating flow field, which evenly covers the multiple battery modules in the battery compartment (1) to achieve heat dissipation and cooling. The hot airflow after heat dissipation is discharged from the air outlet at the top or upper side of the battery compartment (1) by taking advantage of the natural rising characteristics. When the battery compartment (1) When temperature differences occur in different areas, the telescopic rod (6) of the drive redirection component extends and retracts, causing the rack (7) fixedly connected to the telescopic rod (6) to slide up and down along the sliding groove of the vertical plate of the support frame (5). The rack (7) meshes with the transmission gears (8) of multiple heat dissipation components, converting the sliding motion into the rotational motion of the transmission gears (8), which in turn drives the vent pipe (4) fixedly connected to the transmission gears (8) to rotate around its two ends. The vent pipe (4) simultaneously drives the diffuser block (10) to adjust its orientation, so that the air outlet (9) accurately sprays air into the high-temperature area. The entire process is achieved through the shape matching and fitting design of the vent pipe (4) and the connecting groove (3) to achieve sealed air intake and prevent external dust from entering. The heat dissipation components are provided in multiple sets. The design of synchronous rotation of the multiple heat dissipation components can realize the unified angle adjustment of multiple sets of vent pipes (4), ensure that the heat dissipation direction of each battery module is consistent, avoid local overheating, improve heat dissipation efficiency and reduce control complexity. The shape of the connecting groove (3) matches that of the vent pipe (4). The design of the vent pipe (4) being inserted into the connecting groove (3) can enhance the sealing between the vent pipe (4) and the connecting groove (3), reduce the risk of dust entering from the side gaps from the source, and improve the overall dustproof effect. The design of the air outlet (9) with its cross-sectional diameter gradually increasing from one end to the other end of the hollow structure of the air pipe (4) enables the airflow to diffuse naturally when it is ejected, expands the heat dissipation coverage, avoids excessive local wind speed from disturbing the battery module, and improves the heat dissipation uniformity. The sidewall of the air inlet (9) is designed with a spiral guide pattern, which enables the airflow to form a rotating flow field in the air inlet (9). After being sprayed out, it can more evenly wrap the surface of the battery module, enhance the heat exchange efficiency, and reduce the noise generated by the airflow impact. The design of the rack (7) slidingly connecting the support frame (5) with the sliding groove and meshing with the transmission gear (8) can drive multiple sets of transmission gears (8) to rotate synchronously through a single power source, simplifying the transmission structure, reducing the failure rate, and ensuring the accuracy of the vent pipe (4) angle adjustment. The design of the air outlet of the battery compartment (1) being located at the top or side near the top can utilize the physical property of hot air rising to accelerate the exhaust of hot air, forming a highly efficient closed-loop cycle of "intake-heat dissipation-exhaust", further improving heat dissipation efficiency. The goal is to achieve sealing and dust prevention and uniform airflow diffusion through the sealed air intake structure and gradually expanding spiral air outlet (10) of the heat dissipation component, and drive the air pipe (4) to rotate synchronously to adjust the airflow direction through the rack and pinion linkage of the reversing component, so as to achieve the purpose of precise directional heat dissipation, compatibility with the existing battery compartment layout and reduced application cost.
