Description

Technical Field

[0001] The utility model relates to the field of outdoor energy storage cabinets, and more specifically, to a heat dissipation structure of an equipment compartment of an energy storage cabinet. Background Art

[0002] Excessive consumption of fossil fuels leads to the emission of greenhouse gases in the environment, which eventually leads to energy crisis and global warming. Renewable energy sources such as solar energy, wind energy, geothermal energy and biofuels provide effective solutions to these problems. However, almost all renewable energy sources have the problem of uneven and discontinuous energy output. With the rapid increase in the demand for electricity in industrial production and residents' lives, the difference between the peak and valley of electricity consumption during the day and night is increasing. Energy storage systems provide a new path to solve the problems of unstable power output and imbalance between the peak and valley of power supply and demand. They play an important and pivotal role in charging and power supply, and have a positive impact on the construction and operation of the power system. This has brought huge development space to the energy storage market.

[0003] At present, the converters and transformers of energy storage cabinets, which account for a large share of the energy storage market, are usually transported and installed in a split manner. Although transportation is convenient, the equipment is heavy and difficult to install, which increases the on-site installation costs, and the error rate of on-site wiring and installation is relatively high.

[0004] The applicant provides an integrated energy storage cabinet structure that can avoid the aforementioned difficulty in installation. However, due to the relatively harsh outdoor environment, especially the high humidity, the equipment in the equipment cabin that directly adopts air cooling will be adversely affected.

[0005] Therefore, the present application aims to propose a heat dissipation structure for an equipment compartment of an energy storage cabinet, which can avoid the adverse effects of the aforementioned high humidity on the equipment in the equipment compartment. Summary of the invention

The adjustable plate is rotatably connected to the side of the cabin where the bulkhead connecting the equipment cabin and the second heat dissipation chamber is connected to the bulkhead at the front end of the equipment cabin. A linear motor is fixedly connected to the equipment cabin, and the telescopic end of the linear motor moves along the front of the equipment cabin toward the rear end, and the telescopic end of the linear motor is adjustably connected to the adjustable plate. The rotation of the adjustable plate is driven by the feeding of the linear motor, and during the rotation of the adjustable plate, the air outlet or the gas exchange hole can be covered, thereby switching the direction of the airflow.

[0012] Preferably, the telescopic end is rotatably connected to a slider, and the slider is slidably connected to the adjustable plate. The structure enables the linear motor to move the adjustable plate.

[0013] Preferably, an air inlet hole is provided on the wall surface of the second heat dissipation chamber away from the equipment compartment at a position corresponding to the negative pressure fan.

[0014] Preferably, the negative pressure fan is arranged near the rear end of the second heat dissipation chamber. The structure enables the generated airflow to be transported from the rear to the front of the equipment compartment, and discharged outward or returned to the front of the second heat dissipation chamber as needed, for another cycle.

[0015] Preferably, a plurality of partitions are provided in the second heat dissipation chamber, and the partitions partition the second heat dissipation chamber into a continuous S-shaped structure. The structure can extend the length of the heat dissipation air duct, thereby cooling the heated airflow again.

[0016] Preferably, the controller further comprises a temperature sensor disposed in the equipment compartment or the second heat dissipation chamber, wherein the temperature sensor is electrically connected to the linear motor and the controller controls the movement of the adjustable plate according to information obtained by the temperature sensor.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0028] Example:

[0029] A heat dissipation structure of the equipment compartment 3 of an energy storage cabinet, Figure 1 , 2 As shown, the energy storage cabinet includes an equipment compartment 3 for accommodating a transformer 1 and a converter 2, an energy storage compartment 4 for accommodating a battery module, and a temperature control compartment 5 for dissipating heat for the transformer 1, the converter 2, and the battery module. The characteristic is that the equipment compartment 3 is located at the bottom of the energy storage compartment 4, and the temperature control compartment 5 is located on one side of the equipment compartment 3 and the energy storage compartment 4. Along the height direction, the temperature control compartment 5 includes a first heat dissipation chamber 6 for being arranged at the top and a second heat dissipation chamber 7 at the bottom. The first heat dissipation chamber 6 is connected to the battery compartment, and the second heat dissipation chamber 7 is connected to the equipment compartment 3. The second heat dissipation chamber 7 is connected to the equipment compartment 3 and forms a heat dissipation duct with the equipment compartment 3. The outlet of the heat dissipation duct is an adjustable plate 8. By rotating the adjustable plate 8, the opening and closing of the outlet of the heat dissipation duct is switched to adjust the wind direction of the heat dissipation duct.

[0030] Since the humidity at the bottom is relatively high, setting the equipment cabin 3 at the bottom can better protect the energy storage cabin 4. Since the present application also uses airflow to take away the heat of the transformer 1 and the converter 2, it is necessary to make settings to avoid condensation at temperatures with large temperature differences. The present application adopts the structure of an adjustable plate 8, which can be switched to an external circulation or internal circulation mode, thereby reducing the entry of external airflow and reducing the entry of moisture. The humidity of the air is strongly correlated with the height. Setting the energy storage cabin 4 that uses air conditioning for cooling at a higher position can effectively avoid condensation on the outer wall of the energy storage cabin 4.

[0031] The second heat dissipation chamber 7 is provided with a negative pressure fan 9, and the bulkhead connecting the second heat dissipation chamber 7 and the equipment cabin 3 is provided with a heat dissipation air inlet hole 1310 corresponding to the negative pressure fan 9. The negative pressure fan 9 provides the power of the middle airflow in the heat dissipation air duct, so as to blow the airflow from the second heat dissipation chamber 7 into the equipment cabin 3. The front end of the equipment cabin 3 is provided with an air outlet 11, and the bulkhead connecting the front part of the equipment cabin 3 with the second heat dissipation chamber 7 is provided with a gas exchange hole 12. The adjustable plate 8 is rotatably connected to the side of the cabin where the bulkhead connecting the equipment cabin 3 with the second heat dissipation chamber 7 and the bulkhead at the front end of the equipment cabin 3 are connected. The equipment cabin 3 is fixedly connected with a linear motor 16, and the telescopic end of the linear motor 16 moves along the front of the equipment cabin 3 close to the rear end position, and the telescopic end of the linear motor 16 is adjustably connected to the adjustable plate 8. The feeding of the linear motor 16 drives the rotation of the adjustable plate 8. During the rotation of the adjustable plate 8, the air outlet 11 or the gas exchange hole 12 can be covered, thereby switching the direction of the airflow. The telescopic end is rotatably connected to a slider 15, and the slider 15 is slidably connected to the adjustable plate 8. The structure enables the linear motor 16 to move the adjustable plate 8. An air inlet 13 is provided on the wall surface of the second heat dissipation chamber 7 away from the equipment compartment 3, corresponding to the position of the negative pressure fan 9. The negative pressure fan 9 is arranged near the rear end of the second heat dissipation chamber 7. The structure enables the generated airflow to be transported from the rear to the front of the equipment compartment 3, and discharged outward or returned to the front of the second heat dissipation chamber 7 as needed for another cycle. A number of partitions 14 are provided in the second heat dissipation chamber 7, and the partitions 14 separate the second heat dissipation chamber 7 into a continuous S-shaped structure. The structure can extend the length of the heat dissipation duct, thereby cooling the heated airflow again.

[0032] In some embodiments, a temperature sensor is further included in the equipment compartment 3 or the second heat dissipation chamber 7, and the temperature sensor is electrically connected to the controller of the linear motor 16. The movement of the adjustable plate 8 is controlled according to information obtained by the temperature sensor.

[0033] Under normal circumstances, the device is in self-circulation mode, and the negative pressure fan 9 simultaneously sucks air from the air inlet 13 and the second heat dissipation chamber 7, and then enters the equipment compartment 3 for cooling. When the temperature of the equipment compartment 3 is high, it enters the external circulation, closes the air holes in the front of the second heat dissipation chamber 7, and directly discharges the heated air. The structure can effectively reduce the amount of air entering the device, thereby reducing the amount of moisture entering the device.

[0034] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
