Description

Technical Field

[0001] The utility model relates to an air drying device for an energy storage cabinet, belonging to the technical field of energy storage equipment. Background Technique

[0002] During the use of the battery energy storage system, the battery cells will generate heat. Therefore, it is required that the energy storage system adopt a cooling method. However, while cooling the battery cells, the air temperature will be reduced, and the reduction of the air temperature will bring about the formation of condensed water. In the energy storage system, condensed water must be strictly prohibited to prevent the occurrence of safety accidents caused by the reduction of the insulation resistance. Therefore, it is necessary to dry the air inside the energy storage system to reduce the dew point of the air inside the energy storage system and prevent safety accidents caused by condensed water during the battery cooling process.

[0003] At present, the common dehumidification methods inside the energy storage cabinet on the market are mostly air-conditioning dehumidification and semiconductor refrigeration dehumidification. Both of these methods reduce the air temperature and condense and collect the moisture in the air at a specific position to reduce the dew point of the air in the internal area of the energy storage system. However, the above solutions have problems such as high material costs, high energy consumption during use, high system complexity and failure rate, and large installation space occupation.

[0004] To solve the above problems, an air drying device for an energy storage cabinet is proposed in this application. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the existing defects, and provide an air drying device for an energy storage cabinet, which replaces the traditional high-cost air-conditioning dehumidification and semiconductor refrigeration dehumidification schemes by means of a desiccant combined with a fan, effectively reducing the cost and improving the efficiency, and can effectively solve the problems in the background technique.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] An air drying device for an energy storage cabinet includes an energy storage cabinet body. A desiccant box is detachably installed inside the energy storage cabinet body. Desiccant particles are provided inside the desiccant box. A fan is fixedly connected to the desiccant box. A box cover is snap-connected to the desiccant box. When the desiccant particles need to be replaced, the desiccant box and the fan can be detached from inside the energy storage cabinet body, and the desiccant particles can be replaced by opening the box cover. Through the cooperation of the desiccant particles and the fan, when the temperature and humidity sensor inside the energy storage cabinet detects that the internal humidity is relatively high, the fan is started, and the air is driven by the fan to fully contact with the desiccant particles through the desiccant box for drying, and then the dried air is discharged through the desiccant box to avoid the formation of condensation inside.

[0008] As a further improvement of the present utility model, the desiccant box is formed by combining and connecting a first box body and a second box body, and a cavity for accommodating desiccant particles is formed between the first box body and the second box body.

[0009] As a further improvement of the present utility model, ventilation nets are provided on both the first box body and the second box body, and the mesh diameter of the ventilation net is smaller than the diameter of the desiccant particles.

[0010] As a further improvement of the present utility model, a housing is provided at the rear side of the fan, and a mounting bracket is provided at the rear side of the housing.

[0011] As a further improvement of the present utility model, the desiccant box, the fan, the housing, and the mounting bracket are sequentially fixedly connected into an integral structure by screws.

[0012] As a further improvement of the present utility model, a cabinet door is installed on the energy storage cabinet body, and the integral structure is installed on the cabinet door of the energy storage cabinet body.

[0022] Embodiment

[0023] Currently, when designing energy storage systems, due to high cost pressure, using air conditioners for dehumidification will reduce the economic competitiveness of products, and the energy consumption of air conditioners and semiconductor refrigeration dehumidifiers is relatively high, resulting in high usage costs. At the same time, some energy storage systems have relatively high requirements for space occupation, and using air conditioners and semiconductor refrigeration dehumidifiers will occupy a large amount of space, bringing inconvenience in layout.

[0024] Such as Figures 1 - 4As shown, an air drying device for an energy storage cabinet is mainly used to replace traditional air conditioners and semiconductor refrigeration dehumidifiers, and provides an air drying device with lower cost, convenient maintenance, and small space occupation. A desiccant box 1 for storing desiccant particles 7 and a fan 2 for increasing the air flow speed are detachably installed inside the energy storage cabinet 11. An openable box cover 5 is snap-connected to the desiccant box 1. The desiccant particles 7 are used in conjunction with the fan 2. When the temperature and humidity sensor inside the energy storage cabinet 11 detects that the internal humidity is high, the fan 2 is started. The air is driven by the fan 2 to pass through the desiccant box 1 and fully contact the desiccant particles 7 for drying. The dried air is then discharged through the desiccant box 1 to avoid condensation inside. When the desiccant particles 7 need to be replaced, the desiccant box 1 and the fan 2 can be removed from the inside of the energy storage cabinet body 11, and the desiccant particles 7 are replaced by opening the box cover 5, which is convenient for maintenance and replacement of the desiccant particles 7.

[0025] It should be noted that the power supply of fan 2 can be connected to the power supply connector inside the energy storage cabinet 11 through a connector, and the start and stop control method of fan 2 can be linked with the signal of the temperature and humidity sensor. The fan 2 can be started and stopped by the humidity signal detected by the temperature and humidity sensor. The above are all common existing technologies, and the specific detailed structure and principle will not be repeated here.

[0026] In some optional embodiments, the desiccant box 1 is composed of a first box body 3 and a second box body 4, a cavity for accommodating desiccant particles 7 is formed between the first box body 3 and the second box body 4, and a slot for engaging and connecting the box cover 5 is formed at the connection between the first box body 3 and the second box body 4 to facilitate the disassembly and installation of the box cover 5.

[0027] In some optional embodiments, a ventilation net 9 is disposed on both the first box body 3 and the second box body 4 , and the mesh diameter of the ventilation net 9 is smaller than the diameter of the desiccant particles 7 .

[0028] In some optional embodiments, a housing 8 is disposed at the rear side of the fan 2 , and a mounting bracket 6 is disposed at the rear side of the housing 8 . The structure of the mounting bracket 6 can be designed according to actual needs.

[0029] In some optional embodiments, the desiccant box 1, the fan 2, the housing 8, and the mounting bracket 6 are fixedly connected to form an integral structure in sequence by screws 10, and the multiple components are connected by screws 10, so that the overall structure can be easily removed from the inside of the energy storage cabinet 11, and the desiccant particles 7 can be replaced more conveniently. After long-term use, the fan 2 and the desiccant box 1 can be removed and cleaned separately by removing the screws 10.

[0030] In some optional embodiments, a cabinet door 12 is installed on the energy storage cabinet body 11, and the overall structure is installed on the cabinet door 12 of the energy storage cabinet body 11. Figures 3 - 4As described above, a structure that is convenient for disassembly and installation is provided. A C-shaped connecting rod 13 is fixedly installed on the cabinet door 12. The installation bracket 6 is designed in the shape of an inverted U-shaped hook. When installing the overall structure, it only needs to hang the inverted U-shaped hook on the installation bracket 6 on the C-shaped connecting rod 13. When the desiccant particles 7 need to be replaced, disconnect the power connector of the fan 2 and lift the installation bracket 6 upward to remove the overall structure from the inside of the energy storage cabinet body 11, which is convenient for replacing and maintaining the desiccant particles 7 externally.

[0031] In addition, the service life cycle of the desiccant particles 7 can also be estimated according to the temperature and humidity conditions of the project site for regular replacement. Accordingly, the dosage of the desiccant particles 7 and the volume of the internal cavity of the desiccant box 1 can also be adjusted accordingly according to the actual situation, such as adjusting them to be consistent with the maintenance cycle of other equipment in the energy storage cabinet, further reducing the operation and maintenance costs of the energy storage cabinet and improving the market competitiveness.

[0032] An air drying device for an energy storage cabinet. When in use, it cooperates with the desiccant particles 7 and the fan 2. When the temperature and humidity sensor built into the energy storage cabinet 11 detects that the internal humidity is relatively high, the fan 2 is started. The air is driven by the fan 2 to pass through the desiccant box 1 and come into full contact with the desiccant particles 7 for drying, and then the dried air is discharged through the desiccant box 1 to avoid the formation of condensation inside. When the desiccant particles 7 need to be replaced, the desiccant box 1 and the fan 2 can be removed from the inside of the energy storage cabinet body 11, and the desiccant particles 7 can be replaced by opening the box cover 5, which is convenient for maintaining and replacing the desiccant particles 7. By using the form of drying air with desiccant and cooperating with the fan 2 to increase the air flow rate to replace the traditional high-cost air-conditioning dehumidification and semiconductor refrigeration dehumidification solutions, the cost can be effectively reduced, and at the same time, it has the advantage of convenient maintenance.
