Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage air cooling technology, and in particular to a novel energy storage air cooling duct device. Background Technology
[0002] In the field of air-cooling heat dissipation for energy storage systems, traditional air-cooling duct devices face significant technical bottlenecks in practical applications. Existing technologies mostly employ vertical duct structures with uniform cross-sections, resulting in a uniform airflow velocity distribution along the entire length. This fails to adapt to the differentiated heating characteristics of energy storage cells, where "heat dissipation efficiency is low at the bottom and good at the top," leading to significant temperature differences across different parts of the cell and accelerating battery performance degradation. Furthermore, due to their constant cross-section and lack of inclined design, traditional ducts are susceptible to velocity reduction due to gravity during downward airflow, causing uneven heat dissipation, particularly failing to address insufficient heat dissipation at the bottom of the cell. In addition, dust deposits easily accumulate on the surface of vertical ducts, affecting airflow smoothness, reducing heat dissipation efficiency, and posing safety hazards. Existing technologies fail to effectively utilize fluid dynamics principles such as the Venturi effect to optimize airflow acceleration mechanisms, nor can they counteract the obstruction of gravity on the upward flow of hot air through structural design, resulting in high energy consumption and low efficiency in heat dissipation. Summary of the Invention
[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a novel air-cooled duct device for energy storage. A large air hole is opened at the top of the duct, and a small air hole is opened at the bottom of the duct. The duct is designed as a trapezoid, wider at the top and narrower at the bottom, and is tilted so that the front cross-section of the two ducts located in the middle of the energy storage cell is also trapezoidal. This prevents dust accumulation on the duct surface. Furthermore, according to the Venturi effect, the airflow velocity inside the duct gradually increases from top to bottom, making the airflow velocity at the bottom more than twice that at the top. This prevents the airflow velocity from gradually decreasing, which could lead to inconsistent heat dissipation. The airflow generates a component in the vertical direction, offsetting some of the gravitational resistance to the upward movement of hot air. Since the heat dissipation effect at the bottom of the energy storage cell is insufficient during operation, the airflow velocity is positively correlated with the heat, ensuring that all parts of the energy storage cell are at a normal temperature.
[0004] This utility model also provides a novel device with the above-mentioned energy storage air-cooled duct, comprising: a top frame, an air inlet on the front of the top frame, a mounting plate fixedly connected to the lower surface of the top frame, a wind frame fixedly connected to the side surface of the mounting plate, a wind duct fixedly connected to the inner wall of the wind frame, a large air hole at the top of the wind duct, a small air hole at the bottom of the wind duct, a support frame fixedly connected to the side surface of the wind duct, and an energy storage cell disposed on the upper surface of the support frame; and a housing, a door rotatably connected to the front of the housing, an electrical frame fixedly connected to the inner wall of the housing, an electrical compartment fixedly connected to the inner wall of the electrical frame, and an energy storage frame fixedly connected to the side surface of the electrical frame. The above components include a large air vent at the top of the air duct and a small air vent at the bottom. The air duct is designed as a trapezoid, wider at the top and narrower at the bottom, and is tilted so that the front cross-section of the two air ducts located in the middle of the energy storage cell is also trapezoidal. This prevents dust accumulation on the surface of the air duct. According to the Venturi effect, the airflow speed inside the air duct gradually increases from top to bottom, making the airflow speed at the bottom more than twice that at the top. This prevents the airflow speed from gradually decreasing, which could lead to uneven heat dissipation. The airflow generates a component in the vertical direction, which offsets part of the gravitational resistance to the upward flow of hot air. Since the heat dissipation effect at the bottom of the energy storage cell is insufficient when it is working, the airflow speed is positively correlated with the heat, ensuring that all parts of the energy storage cell are at normal temperature.
[0005] According to the present invention, a novel energy storage air-cooled duct device includes two mounting plates located on both sides of the top frame, and two air frames located at the front and rear ends of the duct. These components facilitate the installation of two sets of energy storage cells, with the air frames restricting their movement from both ends of the duct.
[0006] According to the present invention, a novel energy storage air-cooling duct device comprises two ducts located on both sides of a mounting plate, with the two ducts at the adjacent points of the two mounting plates connected to each other. These components allow air ducts on both sides of the energy storage cells to adjust the airflow pattern, enabling the two ducts between two sets of energy storage cells to cooperate with each other.
[0007] According to the present invention, a novel energy storage air-cooled duct device comprises several large air vents arranged in an array at the top of the duct, several small air vents arranged in an array at the bottom of the duct, and several support frames and energy storage cells arranged in an array directly below the mounting plate. These components enable the airflow velocity at the bottom of the duct to be several times that at the top, thereby improving the heat dissipation effect of the energy storage cells located at the bottom of the device.
[0008] According to the present invention, a novel air-cooled duct device for energy storage is provided. The duct is trapezoidal in shape, wider at the top and narrower at the bottom, and is inclined. The front cross-section of the two ducts between the two sets of energy storage cells is trapezoidal. These components enable the duct to utilize the Venturi effect, allowing the airflow velocity at the bottom to be faster than at the top, thus preventing the problem of inferior heat dissipation at the bottom of the energy storage cell compared to the top.
[0009] According to the present invention, a novel energy storage air-cooled duct device includes two doors located on both sides of the enclosure, and the side surface of the energy storage frame is fixedly connected to the inner wall of the enclosure. These components allow the doors to protect both the electrical components and the energy storage components, and to secure the energy storage frame.
[0010] According to the present invention, a novel energy storage air-cooled duct device comprises an inner wall of an energy storage frame fixedly connected to the upper surface of a top frame, and an inner wall of an energy storage frame fixedly connected to the side surface of a wind frame located outside the mounting plate. These components secure the top frame, enabling the wind frame to provide more stable support for the duct.
[0011] According to the present invention, a novel energy storage air-cooled duct device includes an air outlet at the bottom of the air frame and the housing, with the lower surface of the air frame fixedly connected to the inner wall of the housing. These components allow air that has absorbed heat from the energy storage cells to be exhausted to the outside of the housing, providing support for the air frame. Beneficial effects
[0012] Compared with the prior art, this utility model has a large air hole at the top of the air duct and a small air hole at the bottom of the air duct. The air duct is set as a trapezoid with a wider top and a narrower bottom. The air duct is tilted so that the front cross-section of the two air ducts in the middle of the energy storage cell is also trapezoidal. This can prevent dust from accumulating on the surface of the air duct. According to the Venturi effect, the airflow speed inside the air duct gradually increases from top to bottom, so that the airflow speed at the bottom is more than twice that at the top. This will prevent the airflow speed from gradually decreasing and causing uneven heat dissipation. The airflow generates a component in the vertical direction, which offsets part of the resistance of gravity to the upward flow of hot air. Since the heat dissipation effect at the bottom of the energy storage cell is insufficient when it is working, the airflow speed and heat are positively correlated, which can ensure that all parts of the energy storage cell are at normal temperature.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Reference Figure 1-4 This utility model discloses a novel energy storage air-cooled duct device, comprising: a top frame 1, an air inlet 2 on the front of the top frame 1, two mounting plates 3 fixedly connected to the lower surface of the top frame 1 located on both sides of the top frame 1, air frames 4 fixedly connected to the side surfaces of the mounting plates 3, and air ducts 5 fixedly connected to the inner walls of the air frames 4. The air ducts 5 are trapezoidal in shape, wider at the top and narrower at the bottom, and are inclined. Two air frames 4 are located at the front and rear ends of the air ducts 5, and two air ducts 5 are located on both sides of the mounting plates 3. Two air ducts 5 are connected to each other at the junction of the mounting plate 3. A large air hole 6 is opened at the top of the air duct 5. There are several large air holes 6 arranged in an array at the top of the air duct 5. A small air hole 7 is opened at the bottom of the air duct 5. There are several small air holes 7 arranged in an array at the bottom of the air duct 5. A support frame 8 is fixedly connected to the side surface of the air duct 5. An energy storage cell 9 is set on the upper surface of the support frame 8. There are several support frames 8 and energy storage cells 9 arranged in an array directly below the mounting plate 3. The front cross section of the two air ducts 5 between the two sets of energy storage cells 9 is trapezoidal.
[0022] Specifically, external cold air enters the top frame 1 through the air inlet 2, and then enters the air duct 5 inside the air frame 4 through the top frame 1. The cold air absorbs the heat of the energy storage cell 9. A large air hole 6 is opened at the top of the air duct 5, and a small air hole 7 is opened at the bottom of the air duct 5. The air duct 5 is set as a trapezoid with a wider top and a narrower bottom. The air duct 5 is tilted so that the front cross-section of the two air ducts 5 in the middle of the energy storage cell 9 is also trapezoidal. This can prevent dust from accumulating on the surface of the air duct 5. According to the Venturi effect, the airflow speed inside the air duct 5 gradually increases from top to bottom, so that the airflow speed at the bottom is more than twice that at the top. This will prevent the airflow speed from gradually decreasing and causing uneven heat dissipation. The airflow generates a component in the vertical direction, which offsets part of the resistance of gravity to the rise of hot airflow. Since the heat dissipation effect at the bottom of the energy storage cell 9 is insufficient when it is working, the airflow speed and heat are positively correlated, which can ensure that all parts of the energy storage cell 9 are at normal temperature.
[0023] The enclosure 10, the air frame 4, and the bottom of the enclosure 10 are provided with air outlets. The lower surface of the air frame 4 is fixedly connected to the inner wall of the enclosure 10. The front of the enclosure 10 is rotatably connected to the door 11. There are two doors 11 located on both sides of the enclosure 10. The inner wall of the enclosure 10 is fixedly connected to the electrical frame 12. The inner wall of the electrical frame 12 is fixedly connected to the electrical compartment 13. The side surface of the electrical frame 12 is fixedly connected to the energy storage frame 14. The side surface of the energy storage frame 14 is fixedly connected to the inner wall of the enclosure 10. The inner wall of the energy storage frame 14 is fixedly connected to the upper surface of the top frame 1. The inner wall of the energy storage frame 14 is fixedly connected to the side surface of the air frame 4 located outside the mounting plate 3.
[0024] Specifically, the electrical frame 12 and the energy storage frame 14 provide support for the electrical compartment 13 and the energy storage components, respectively. A door 11 is provided to facilitate the sealing of the enclosure 10 and prevent external debris from entering the enclosure 10 and affecting the operation of its internal components.
[0025] Working principle: During the operation of the device, the electrical frame 12 and the energy storage frame 14 provide support for the electrical compartment 13 and the energy storage components, respectively. A door 11 is provided to facilitate the sealing of the enclosure 10, preventing external debris from entering the enclosure 10 and affecting the operation of its internal components. Cold air from outside enters the top frame 1 through the air inlet 2, and then enters the air duct 5 inside the air frame 4 through the top frame 1. The cold air absorbs heat from the energy storage cells 9. A large air hole 6 is opened at the top of the air duct 5, and a small air hole 7 is opened at the bottom of the air duct 5. The air duct 5 is designed as a trapezoid, wider at the top and narrower at the bottom. The inclined design of the air duct 5 makes the front cross-section of the two air ducts 5 located in the middle of the energy storage cell 9 trapezoidal, which can prevent dust accumulation on the surface of the air duct 5. According to the Venturi effect, the airflow speed inside the air duct 5 gradually increases from top to bottom, making the airflow speed at the bottom more than twice that at the top. This prevents the airflow speed from gradually decreasing, which would lead to uneven heat dissipation. The airflow generates a component in the vertical direction, which offsets part of the resistance of gravity to the upward flow of hot air. Since the heat dissipation effect at the bottom of the energy storage cell 9 is insufficient when it is working, the airflow speed is positively correlated with the heat, which can ensure that all parts of the energy storage cell 9 are at normal temperature.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
