Description

Technical Field

[0001] This utility model relates to the field of energy storage dehumidification technology, specifically to an energy storage container dehumidification system and an energy storage container. Background Technology

[0002] With the promotion and application of new energy sources such as solar and wind power, and the continuous development of energy storage technology, lithium batteries have gradually become the mainstream energy storage product due to their advantages such as high energy density, low self-discharge rate, and environmental friendliness. In the application of energy storage containers, liquid-cooled battery packs, as a novel energy storage solution, have attracted widespread attention due to their efficient heat dissipation performance. However, in practical applications, energy storage containers face severe outdoor environmental challenges, especially under harsh conditions such as high temperature and high humidity, where the performance of liquid-cooled battery packs is easily affected, potentially leading to overall insulation failure and safety hazards.

[0003] Traditional dehumidification methods for energy storage containers involve installing dehumidifiers separately inside the container. However, relying solely on dehumidifiers has limited dehumidification capacity and cannot guarantee uniform dehumidification throughout the container, resulting in some areas experiencing dehumidification difficulties. Furthermore, existing temperature and humidity control systems have operational issues, such as high relative humidity and condensation within the container. These problems not only affect the normal operation of electrical equipment but may also lead to thermal fatigue failure, impacting equipment reliability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a dehumidification system and container for energy storage containers, which improves the dehumidification effect inside the container and reduces the risk of condensation caused by high relative humidity inside the container.

[0005] To address the aforementioned technical problems, this utility model provides an energy storage container dehumidification system, comprising: container; An air circulation system includes multiple fans arranged inside the container. A dehumidification system, comprising multiple dehumidifiers arranged inside the container; The ventilation system includes a fire exhaust inlet and a fire exhaust outlet on the container, and a fire exhaust fan installed on the fire exhaust outlet. An internal temperature and humidity sensor is installed inside the container, and an external temperature and humidity sensor is installed outside the container. The fire exhaust fan ventilates the container based on the monitoring data of the internal and external temperature and humidity sensors.

[0006] In some embodiments, a liquid cooling unit and a liquid cooling plate are included, wherein the liquid cooling unit performs auxiliary dehumidification of the interior of the container by controlling the temperature of the liquid cooling medium in the liquid cooling plate.

[0007] In some embodiments, the fan is an axial flow fan.

[0008] In some embodiments, the fan and / or dehumidifier is provided with a wind guide motor and a wind guide plate, wherein the wind guide motor is used to control the rotation of the wind guide plate.

[0009] In some embodiments, the fire exhaust inlet and the fire exhaust outlet are respectively located near the bottom and near the top of the container.

[0010] In some embodiments, louvers are provided at both the fire exhaust inlet and the fire exhaust outlet.

[0011] In some embodiments, a filter screen is provided at the fire exhaust inlet, and the filter screen is located on the outside of the louvers of the fire exhaust inlet.

[0012] In some embodiments, a control system is included, the control system including a controller, the controller being electrically connected to a dehumidifier, a fan, a wind-guided motor, a temperature and humidity sensor, a fire-fighting fan, and a liquid-cooled unit, respectively, for adjusting the dehumidifier, fan, wind-guided motor, temperature and humidity sensor, fire-fighting fan, and liquid-cooled unit according to the monitoring data of the internal temperature and humidity sensor and the external temperature and humidity sensor.

[0013] In some embodiments, the control system includes a remote control device for acquiring local weather forecasts and controlling the controller based on the local weather forecasts.

[0014] On the other hand, an energy storage container includes the aforementioned energy storage container dehumidification system, and also includes multiple rows of battery clusters, with the fan arranged between two adjacent battery clusters in each row, and the fan arranged between two adjacent rows of battery clusters, and the fan is arranged on each inner wall of the container.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model combines a fan and a dehumidifier to promote air circulation inside the container, thereby improving the dehumidification effect. By arranging multiple temperature and humidity sensors at different locations inside the container, the operation of the fans and dehumidifiers at different locations is controlled according to the temperature and humidity changes at different locations, thus achieving precise monitoring and intelligent control of the environment inside the container.

[0016] 2. This utility model sets up an air guide structure at the fan outlet to control the fan's blowing direction. It controls the airflow direction based on the temperature and humidity monitored at different locations, thereby enhancing the directional dehumidification capability and overcoming the shortcomings of existing dehumidification systems that lack intelligent management functions.

[0017] 3. This utility model involves arranging external temperature and humidity sensors on the outside of the container. When the internal temperature and humidity are detected to be higher than a certain value of the external temperature and humidity, the fire-fighting fan is activated to ventilate the inside of the container. This effectively solves the problem of high relative humidity and condensation inside the container in the prior art, and ensures the normal operation of electrical equipment.

[0018] 4. This utility model controls the temperature of the liquid cooling medium by operating the liquid cooling unit, thereby increasing the ambient temperature at the location of the liquid cooling plate and assisting in dehumidification.

[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] like Figure 1 As shown, this utility model provides an energy storage container dehumidification system, including an air circulation system, a dehumidification system and a ventilation system installed in the container 1.

[0025] like Figure 1As shown, the air circulation system includes multiple fans 2, the number of which can be set according to the size of the container 1. The fans can be axial flow fans, constant flow fans, or other types of fans to drive the air circulation inside the container 1.

[0026] The dehumidification system includes multiple dehumidifiers 3, which are either semiconductor dehumidifiers 3 or industrial constant temperature dehumidifiers 3.

[0027] The ventilation system includes a fire exhaust inlet 4 and a fire exhaust outlet 5 located on container 1, and a fire exhaust fan 6 installed on the fire exhaust outlet 5. An internal temperature and humidity sensor is installed inside container 1, and an external temperature and humidity sensor is installed outside container 1. The fire exhaust fan 6 ventilates the interior of container 1 based on the monitoring data from the internal and external temperature and humidity sensors. Specifically, when the external temperature and humidity (i.e., temperature and humidity) of container 1 is detected to be lower than the internal temperature and humidity, the fire exhaust fan 2 is activated to directly ventilate the interior of container 1, rapidly reducing the temperature and humidity inside container 1. This effectively solves the problems of high relative humidity inside the container and condensation in some containers in existing technologies, ensuring the normal operation of electrical equipment.

[0028] like Figure 3 , 4 As shown, the fire exhaust inlet 4 and the fire exhaust outlet 5 are respectively located near the bottom and top of the container 1, which can quickly replace all the air in the container 1. Both the fire exhaust inlet 4 and the fire exhaust outlet 5 are equipped with louvers 7. The fire exhaust inlet 4 is equipped with a filter screen 8, which is made of wire mesh and is located on the outside of the louvers 7 of the fire exhaust inlet 4.

[0029] To improve the overall dehumidification effect inside container 1, multiple internal temperature and humidity sensors are evenly distributed at different locations on the top, bottom, and middle of container 1 to monitor temperature and humidity changes in various areas of container 1 in real time. An air guide structure is installed at the outlet of fan 2, comprising an air guide motor and an air guide plate. The air guide motor controls the rotation of the air guide plate, thereby controlling the air outlet angle of fan 2. This air guide structure is similar to the air guide structure at the air outlet of a household air conditioner. It can be understood that, based on data from the temperature and humidity sensors at different locations, adjusting the angle of the air guide plate directs the airflow from fan 2 towards areas with higher humidity. This causes the air in areas with higher temperature and humidity to circulate, mix with air from other areas, and enter dehumidifier 3 for dehumidification, further improving the overall dehumidification effect inside container 1.

[0030] To further improve the dehumidification effect, this invention incorporates a liquid cooling unit. The liquid cooling unit reduces the heat dissipation during the circulation of the liquid cooling medium, causing the temperature of the liquid cooling plate in each battery pack to rise, thereby increasing the ambient temperature around the liquid cooling plate and assisting in dehumidification.

[0031] This utility model also includes a control system, which includes a controller and a remote control device. The controller is electrically connected to the dehumidifier 3, fan 2, air guide motor, temperature and humidity sensor, fire-fighting fan 6 and liquid-cooled unit respectively, and is used to regulate the dehumidifier 3, fan 2, air guide motor, temperature and humidity sensor, fire-fighting fan 6 and liquid-cooled unit according to the monitoring of the internal temperature and humidity sensor and the external temperature and humidity sensor.

[0032] The remote control device communicates with the controller via a wireless or wired network to achieve remote monitoring and intelligent management of the entire dehumidification system. The remote control device is also used to obtain local weather forecasts and control the controller according to the local weather forecasts.

[0033] like Figure 1 As shown, eight battery clusters 9 are installed inside the container 1, arranged in two rows of four. A fan 2 is installed between adjacent battery clusters 9 in each row, and between adjacent rows of battery clusters 9. The fans 2 are also installed on each inner wall of the container 1. The fans 2 positioned between the battery clusters 9 are located near the top or bottom of the battery clusters 9. The air intake of the fans 2 positioned between the battery clusters 9 faces the inner wall of the container 1, and the air outlet faces the interior of the container 1, which facilitates effective airflow inside the container 1.

[0034] The working principle of this energy storage container dehumidification system is as follows: Using multiple internal temperature and humidity sensors, the temperature and humidity of different areas inside container 1 are monitored. The controller controls the operation of fans 2 and dehumidifiers 3 in different locations according to the temperature and humidity changes in different areas, and controls the air blowing direction of fans 2 by controlling the angle of the air guide plate to carry out directional dehumidification and cooling. Meanwhile, the controller compares the monitoring values ​​of the internal and external temperature and humidity sensors. When the difference between the temperature or humidity inside container 1 and the temperature or humidity outside container 1 exceeds the threshold, the controller controls the fire motor to start and ventilate the inside of container 1. At the same time, by operating the liquid cooling unit to control the temperature of the liquid cooling medium, the ambient temperature at the location of the liquid cooling plate is increased, which assists in dehumidification; Meanwhile, the remote control device is combined with local weather forecasts to form an early warning system. In response to weather changes, even if the temperature and humidity inside container 1 meet the requirements, humidity control is carried out in advance to reduce the risk of condensation caused by weather changes.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
