For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

In the description of the present invention, it should be understood that the terms "left", "right", "front", "back", "top", "bottom", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

Example 1

As shown in Figures 1 to 9, an energy storage cabinet duct structure includes a duct main body 1, a duct side plate 2 and a fan 3. The head end of the duct main body 1 is provided with a duct air inlet 11, and the duct air inlet 11 is connected to the air conditioning outlet 101 of the air conditioner 10. The duct side plate 2 is arranged at the end of the duct main body 1 and is through-connected. A plurality of duct air outlets 12 are arranged on the duct side plate 2; the fan 3 is arranged on the side wall of the duct main body 1 and is through-connected to the duct main body 1.

In the utility model, the fan 3 is arranged in the air duct of the energy storage cabinet, and there is no need to arrange a fan on the battery plug-in box, which can not only greatly reduce the number of fans arranged in the overall product, effectively reduce energy consumption, and reduce the failure probability of equipment; at the same time, it can also effectively solve the insufficiency of relying solely on the air volume of the air conditioner, increase the air volume required for heat exchange of the overall energy storage cabinet, and realize timely heat dissipation inside the energy storage cabinet and the battery plug-in box through the arrangement of the air duct structure, with a good heat exchange effect, which greatly reduces the failure risk and safety hazards of the overall energy storage product.

Specifically, the air duct main body 1 is arranged vertically in the direction of the air duct side plate 2, that is, the air duct side plate 2 is arranged on one side of the battery cluster rack 7 contained in the energy storage cabinet and the battery plug box 8 arranged thereon, so as to facilitate the dissipation of the heat generated during the operation of the battery plug box 8 on the battery cluster rack 7, and the heat dissipation effect is good; the air conditioning component can be obtained from the prior art, and the cold air generated by the air conditioner is sent into the air duct main body 1 through the air conditioning outlet 101 to dissipate the heat of the energy storage cabinet and the electrical components arranged therein, and the heat generated by the energy storage cabinet is collected through the air conditioning inlet 102 and re-cooled before being blown out from the air conditioning outlet. It should be noted that the head end and the end end mentioned above are defined according to the direction of air flow, which is only for the convenience of describing and understanding the present technical solution, and does not constitute a limitation to the present application.

The ventilation cycle process inside the energy storage cabinet in the present application is as follows: cold air is blown out from the air outlet 101 of the air conditioner, enters the air duct main body 1 located at the top of the battery cluster rack 7, passes through the air duct side plate 2 and the air outlet 12 thereon so that the cold air is blown to the back or side area of the battery cluster rack 7 and the battery plug box 8, and then enters each battery plug box 8 to exchange heat with the battery 821, thereby taking away heat from the battery, and the battery temperature drops. After passing through the battery plug box 8, it flows into the internal area of the cabinet between the battery plug box and the air conditioner, and then is sucked into the interior of the air conditioner by the air inlet 102 of the air conditioner for heat exchange. After the temperature of the air drops, it is blown into the air duct of the energy storage cabinet from the air outlet 101 of the air conditioner, thereby completing a complete ventilation cycle inside the energy storage cabinet.

On the basis of the above technical solution, it also includes an air duct anti-backflow component, which includes an air duct one-way plate 4 and a limiting plate 5. The air duct one-way plate 4 is arranged on the fan outlet side of the fan 3 and the top end is hinged to the inner wall of the air duct main body 1, and the limiting plate 5 is arranged at the bottom end of the air duct one-way plate 4 and is located on the side close to the fan 3.

By setting up an air duct anti-backflow component at the fan outlet, the reverse flow of air is effectively prevented under the cooperation of the limit plate 5 and the air duct one-way plate 4, that is, the phenomenon of air flow short circuit caused by the air conditioner's wind being blown back in the opposite direction is prevented, and the air from the air conditioner is ensured to flow through the battery plug box, which has a good heat dissipation effect and also ensures that the air conditioner monitors the temperature changes inside the battery plug box. When the fan is turned on, the air volume inside the energy storage cabinet air duct can be increased. When the fan is turned off, it can effectively prevent the air blown out by the air conditioner from flowing in the opposite direction through the fan to cause an air short circuit, so that the air at the air inlet of the air conditioner can flow through the battery plug box and the battery to detect the change of air temperature.

Based on the above technical solution, the fans 3 are arranged in plurality and symmetrically on the side wall of the air duct body 1 .

By providing multiple fans 3 on the air duct body 1, the required heat exchange air volume in the overall energy storage cabinet can be effectively increased. In combination with the air conditioner, the heat dissipation requirements of the energy storage cabinet under different rates of charge and discharge can be met. It can also avoid the potential safety hazard caused by the failure of only one fan causing the overall energy storage cabinet to not dissipate heat in time. In actual use, the number of fans to be turned on can be selected according to the heat exchange requirements, which is more convenient to use and has better applicability. More preferably, the type of the fan can be an axial flow fan or a centrifugal fan, etc.

On the basis of the above technical solution, an air duct baffle 21 is arranged on the inner wall of the air duct side plate 2 , and the air duct baffle 21 is arranged in a position close to the air duct main body 1 in the air duct side plate 2 .

By providing an air duct baffle 21 on the inner side wall of the air duct side plate 2 of the energy storage cabinet, especially at a position close to the air duct body 1, i.e., close to the air inlet of the air duct side plate, the internal pressure in the air duct side plate 2 can be effectively improved, and the air volume at the multiple air duct outlets 12 arranged from top to bottom can be basically consistent, thereby achieving a more uniform heat dissipation effect for the multiple battery plug-in boxes 8 on the battery cluster rack 7 in the energy storage cabinet. More preferably, the air duct baffle 21 is arranged obliquely on the inner side wall of the air duct side plate 2.

On the basis of the above technical solution, a vertical plate 22 is fixedly provided inside the air duct side plate 2 , and a plurality of transverse ventilation slots 23 are opened on the vertical plate 22 .

By providing the vertical plate 22 in the air duct side plate 2 and the transverse ventilation slots 23 thereon, the air volume on the left and right sides of the vertical plate 22 in the air duct side plate 2 can be made more uniform when the air duct side plate 23 is wider or the corresponding battery cluster racks 7 are more, thereby ensuring the uniformity of the heat dissipation effect between multiple columns of battery clusters and improving the operation stability. More preferably, the vertical plate 22 can be provided in accordance with the width or number of columns of the battery cluster racks 7 in the energy storage cabinet, so as to ensure the heat dissipation effect of the battery clusters and battery plug boxes in each column.

The working process of the utility model is:

When the battery plug box 8 in the energy storage cabinet is in the working state of charging and discharging, the fan 3 in the air duct body 1 is turned on, and the air duct one-way plate 4 is blown open by the fan 3; at the same time, the air conditioner 10 is in cooling operation, and the air inside the cabinet air duct is powered by the air conditioner 10 and the fan 3 for circulation. According to the heat dissipation air volume required for the charging and discharging work of the battery plug box at different rates, the number of fans turned on can be selected to meet different heat dissipation requirements, with good heat dissipation effect and stronger applicability.

When the battery box 8 in the energy storage cabinet is not in the working state of charging and discharging, the fan 3 in the air duct body 1 is turned off, and the air conditioner 10 only performs ventilation operation without cooling. At this time, the air inside the cabinet air duct is only powered by the air conditioner 10 for circulation operation; when the fan 3 is turned off, the duct one-way plate 4 is in a vertical downward state under the action of gravity. Since the wind blown out by the air conditioner 10 has a certain pressure, the duct one-way plate 4 will generate an outward force, but due to the obstruction of the limit plate 5 at its bottom end, the duct one-way plate 4 can only be limited to a vertical state, so that the wind blown out by the air conditioner 10 cannot be blown back through the fan 3, so that the air flow short circuit will not occur, ensuring that the air entering the air inlet 102 of the air conditioner flows through the battery box 8, ensuring that the air conditioner 3 can monitor the temperature changes inside the battery box.

The present application also provides an energy-saving energy storage cabinet, including the above-mentioned energy storage cabinet air duct structure, and also including an energy storage cabinet body 6, a battery cluster frame 7 and a battery plug-in box 8, wherein the battery cluster frame 7 is arranged in the energy storage cabinet body 6 and is located at the bottom end of the air duct body 1, and the air duct side plate 2 is correspondingly arranged on one side of the battery cluster frame 7, the air conditioner 10 is arranged on the energy storage cabinet body 6 and the air conditioning air inlet 102 and the air conditioning air outlet 101 are arranged on the energy storage cabinet body 6 on one side close to the battery cluster frame 7, and the battery plug-in box 8 is provided in plurality and is evenly arranged on the battery cluster frame 7.

The utility model also provides an energy-saving energy storage cabinet. By improving the internal ventilation structure of the battery plug-in box 8 and cooperating with the improved ventilation structure of the energy storage cabinet described above, the normal heat dissipation and heat exchange performance of the energy storage cabinet can be met, and the operation stability is good. Moreover, the number of fans is reduced without increasing safety hazards, thereby reducing the cost of the whole machine, reducing the power consumption of the overall energy storage cabinet, and being more energy-efficient.

Specifically, the air conditioner 10 is provided with an air conditioning inlet 102 and an air conditioning outlet 101, and a plurality of battery plug boxes 8 are installed on the battery cluster frame 7. The battery plug boxes 8 will generate heat during the charging and discharging process, and this part of the heat is circulated and cooled through the air duct main body 1, the air duct side plate 2, the fan 3 and the air conditioner 10 components provided in the energy storage cabinet 6. In addition, an electrical device 9 is also provided on one side of the battery cluster frame 7 in the energy storage cabinet to realize the normal function of the energy storage cabinet; more preferably, a partition is provided between the electrical device 9 and the battery cluster frame 7, and the partition is covered with a heat preservation material, so that the space on both sides is completely independent, and air and heat exchange cannot be performed, that is, reducing the more adverse effects on the heat of the batteries in the battery cluster frame.

On the basis of the above technical solution, the battery plug box 8 includes a box body 81, a battery module 82, a plug box air inlet 83 and a plug box air outlet 84. The battery module 82 is arranged in the box body 81 and there are intervals between each other. The battery module 82 includes a plurality of batteries 821 and there are gaps between each other. The plug box air inlet 83 and the plug box air outlet 84 are both opened on the box body 81.

The battery box 8 provided in the utility model is not provided with a fan. For the entire battery cluster and energy storage cabinet, the number of fans is greatly reduced, which effectively reduces the failure probability of the equipment, reduces energy consumption, and achieves energy-saving effects. At the same time, by improving the internal air duct of the battery box 8, an efficient air duct structure without a power source is formed inside the battery box, achieving better ventilation and heat dissipation effects inside the battery box 8, cooperating with the air duct structure of the energy storage cabinet to jointly achieve the heat dissipation performance of the overall energy storage cabinet and improve the operating stability of the entire machine.

Based on the above technical solution, the plug-in box air inlet 83 is arranged on the back of the box body 81 and corresponds to the air duct outlet 12, the plug-in box air outlet 84 is symmetrically arranged at the end of the box body 81, and a plug-in box baffle 85 is arranged in the box body 81 and is arranged on one side of the battery module 82.

In a preferred embodiment of the present invention, the plug-in box air inlet 83 is arranged on the back of the battery plug-in box 8, that is, the plug-in box air inlet 83 corresponds to the air duct outlet 12 arranged on the air duct side plate 2, and the wind in the air duct main body 1 flows out from the air duct outlet 12 through the air duct side plate 2, and directly enters the plug-in box air inlet 83 accordingly. Under the blocking effect of the plug-in box baffle 85, the air flows forward along the side wall of the battery module 82, and a certain gap is also arranged between the batteries 821 and the batteries 821 in the battery module 82, so that in the process of air flowing along the side wall of the battery module 82, it also flows through the gap between the batteries 821, and then gathers in the space area between the battery modules 82 and flows straight forward, and finally leaves the battery plug-in box 8 after passing through the plug-in box air outlet 84, thereby realizing the heat dissipation of multiple batteries inside the battery plug-in box 8.

Based on the above technical solution, dustproof nets are provided inside the plug-in box air inlet 83 and the plug-in box air outlet 84 .

By providing dustproof nets on both the plug-in box air outlet 84 and the plug-in box air inlet 83, dust can be effectively reduced from entering the battery plug-in box 8, maintaining the internal cleanliness, thereby ensuring the safe and stable operation performance of the energy storage cabinet.

The utility model improves the internal air duct structure of the energy storage cabinet 6, the setting position of the fan 3, and the internal ventilation structure of the battery plug box 8 as a whole, so as to meet the ventilation and heat dissipation requirements of the overall energy storage cabinet under various working conditions, such as in a non-charging and discharging state, in a charging and discharging state, and in a charging and discharging state with different multiples. At the same time, it greatly reduces the number of fans used, reduces power consumption and cost, is more energy-efficient, and also reduces the failure probability of the equipment, and has excellent practical performance in actual application.
