Technical Field
[0001] This utility model relates to the field of energy storage cabinet technology, specifically a heat dissipation channel for a backpack-type forced thermal convection energy storage cabinet. Background Technology
[0002] As a crucial hub for power storage and distribution, the heat dissipation efficiency of energy storage cabinets plays a vital role in ensuring the stable and reliable operation of the entire power system. Existing heat dissipation methods for energy storage cabinets primarily rely on natural convection or forced air cooling with a single fan. From the perspective of heat transfer principles, natural convection relies on the slow heat conduction and convection of air under natural conditions, resulting in low thermal conductivity and a slow heat dissipation rate, making it difficult to efficiently dissipate the large amount of heat accumulated by the continuous operation of high-power electronic components inside the cabinet. While forced air cooling with a single fan accelerates the heat exchange process to some extent by using external mechanical force to drive airflow, the lack of refined planning of airflow paths and overall consideration of balanced heat distribution easily leads to uneven heat distribution within the cabinet in actual operation scenarios. This can cause localized overheating "hot spots," leaving some electronic components under prolonged high-temperature stress, severely affecting their electrical performance and lifespan. Therefore, there is an urgent need for an innovative heat dissipation architecture that can achieve efficient heat exchange and uniform heat distribution, so as to comprehensively improve the heat dissipation performance of the energy storage cabinet and meet the stringent heat dissipation requirements of modern high-power-density power electronic equipment.

The heat dissipation backpack guides the hot air, allowing the hot air to be discharged from the ventilation openings on both sides of the heat dissipation port, effectively reducing the airflow speed, increasing static pressure, and helping the hot air to be discharged from the cabinet more smoothly, thus ensuring the high efficiency of heat exchange.
[0004] This utility model provides the following technical solution: a heat dissipation channel for a backpack-type forced convection energy storage cabinet, comprising a cabinet body and a base, characterized in that: a heat dissipation vent is formed at the upper end of the cabinet body, a fan is installed in the heat dissipation vent through a fan mounting plate, a heat dissipation backpack is connected to the heat dissipation vent, the heat dissipation vent and the heat dissipation backpack are connected, the heat dissipation backpack includes two top plates arranged in a V-shape, side plates are formed at both ends of the top plates, a first air outlet plate and a second air outlet plate are connected to the lower ends of the top plates and side plates, a ventilation opening is formed between the first air outlet plate and the second air outlet plate, the ventilation opening is located on the heat dissipation vent and the two are connected, and the width of the ventilation opening is greater than the width of the heat dissipation vent.
[0005] To support the second air outlet plate, reduce its vibration, and lower noise during heat dissipation, one side of the heat dissipation vent is connected to the end face of the first air outlet plate, and a support strip mounting plate is connected to the bottom of the other side of the heat dissipation vent. The support strip mounting plate is aligned with the second air outlet plate, and a support strip connects the support strip mounting plate and the second air outlet plate.

[0008] In order to guide the hot air and reduce turbulence, guide vanes are connected to the side wall of the second cavity.
[0009] To facilitate maintenance of the internal equipment, door panels are hinged to both the front and rear of the first cavity.
[0010] In order to place the battery, placement ridges are also arranged in an array on the side wall of the second cavity, and the opposite placement ridges are used to place the battery.

[0013] (2) The heat dissipation vents are located at the top of the cabinet. The heat dissipation backpack guides the hot air. The herringbone-shaped top plate can effectively reduce the airflow speed, increase the static pressure, and help the hot air to be discharged from the cabinet more smoothly, thus ensuring the high efficiency of heat exchange.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] Please see Figures 1 to 5This utility model provides a technical solution: a heat dissipation channel for a backpack-type forced convection energy storage cabinet, including a cabinet body 2 and a base 1. The cabinet body 2 is mounted on the base 1. A heat dissipation vent 4 is formed at the upper end of the cabinet body 2. The heat dissipation vent 4 has a rectangular frame. A fan 42 is mounted inside the heat dissipation vent 4 via a fan mounting plate 41. The fan mounting plate 41 is fastened to the upper or lower end of the heat dissipation vent 4 by fasteners or direct welding. The fan 42 is connected to the fan mounting plate 41 by fasteners. The fan 42 is an axial flow fan. A heat dissipation backpack 3 is welded to the heat dissipation vent 4. The heat dissipation vent 4 and the heat dissipation backpack 3 are connected. The heat dissipation backpack 3 includes two top plates 31 arranged in a herringbone pattern. The top plates 31 guide the airflow. Side plates 32 are formed at both ends of the top plates 31. The side plates 32 protect the heat dissipation backpack 3 and prevent foreign objects from entering the cabinet body 2 through the heat dissipation backpack 3. The herringbone arrangement of the top plates 31 allows for... The airflow velocity is reduced, the static pressure is increased, and the hot air is discharged from the cabinet more smoothly, ensuring the high efficiency of heat exchange. The lower ends of the top plate 31 and the side plate 32 are connected to the first air outlet plate 33 and the second air outlet plate 34. A vent is formed between the first air outlet plate 33 and the second air outlet plate 34. The vent is set on the heat dissipation port 4 and the two are connected. The width of the vent is greater than the width of the heat dissipation port 4. The airflow in the cabinet 2 flows upward under the action of the axial flow fan 42 and is drawn into the heat dissipation port 4. The airflow flows into the heat dissipation backpack 3 through the heat dissipation port 4. Under the guidance of the top plate 31, the airflow flows from the top to both sides and is discharged from both ends of the vent, realizing the flow of hot air in the cabinet 2 and realizing the heat dissipation of the battery. At the same time, the heat dissipation backpack 3 is a heat exchange material with a high thermal conductivity, which further improves the heat dissipation efficiency of the heat dissipation backpack 3 and maintains the thermal balance inside the cabinet 2.
[0024] like Figure 3 As shown, one side of the heat dissipation vent 4 is welded to the end face of the first air outlet plate 33, and a support strip mounting plate 43 is welded to the bottom of the other side of the heat dissipation vent 4. The support strip mounting plate 43 is aligned vertically with the second air outlet plate 34. A support strip 44 is connected between the support strip mounting plate 43 and the second air outlet plate 34. The support strip 44 is welded to the support strip mounting plate 43. The support strip 44 supports the second air outlet plate 34, making the second air outlet plate 34 stable under force and preventing the second air outlet plate 34 from vibrating under the action of wind, further reducing the noise generated during heat dissipation.
[0025] like Figure 2 As shown, the first air outlet plate 33 and the second air outlet plate 34 are provided with an array of small holes, which are rectangular or round. The array of small holes increases the air outlet area and further improves the heat dissipation efficiency.
[0026] like Figure 4 and 5As shown, a partition is provided inside the cabinet 2, which divides the cabinet 2 into a first cavity 21 and a second cavity 22. An air inlet 25 is provided on the bottom surface of the cabinet 2. Part of the air inlet 25 is located at the bottom of the first cavity 21, and the other part is located at the bottom of the second cavity 22. Cold air is sent into the interior of the cabinet 2 through the air inlet 25. The cold air enters the cabinet 2 under the dual action of pressure difference and suction of fan 42, providing a sufficient cold source for the subsequent heat exchange process.
[0027] like Figure 5 As shown, a guide vane 24 is connected to the side wall of the second cavity 22. The surface of the guide vane 24 is coated with a low-friction, high-temperature resistant coating, which changes the fluid flow trajectory and can guide the hot air to move steadily in a predetermined direction, effectively reducing turbulence, reducing energy loss caused by disordered fluid collisions, and improving heat dissipation efficiency.
[0028] like Figure 1 and 5 As shown, door panels are hinged to both the front and rear of the first cavity 21. The door panels seal the front and rear sides of the first cavity 21. At the same time, opening the door panels also facilitates maintenance of the equipment inside the first cavity 21.
[0029] like Figure 4 As shown, placement ridges 23 are also arrayed on the side wall of the second cavity 22. Batteries are placed on the opposite placement ridges 23. The placement ridges 23 are L-shaped profiles and are fixed to the inner wall of the second cavity 22 by fasteners, so that the two ends of the battery can be placed on the folded edges of the placement ridges 23 on both sides to ensure the stability of the battery.
[0030] Working principle: Cold air enters the cabinet through the bottom air inlet. Under the action of the fan, the cold air flows upward and comes into full contact with the batteries and other components inside the cabinet to complete heat exchange. The heated air continues to flow upward along the cabinet and rises under the guidance of the guide vanes, causing the hot air to gather at the top of the cabinet. Finally, under the action of the fan, the hot air is drawn into the heat dissipation backpack area. Guided by the top plate, the hot air is discharged from the vents, realizing convective heat exchange with the external environment. At the same time, the heat dissipation backpack is made of thermally conductive material, which facilitates heat exchange, accelerates heat transfer, and causes the temperature of the cabinet to drop rapidly.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
