[0028] The technical solution provided by the present invention has the following advantages:

[0029] 1. The dehumidification container system provided by the present invention includes a container, a dehumidification component, a condensation component and a control system. The container has a loading chamber, and the loading chamber is suitable for placing a battery system; the dehumidification component includes a humidity sensor and a dehumidifier, the humidity sensor is installed in the loading chamber to monitor the humidity data of the loading chamber, the dehumidifier is installed on the container, and the dehumidifier has a second air inlet and a second air outlet connected to the loading chamber; the condensation component includes at least one condensation plate and a water collecting structure, the condensation plate is installed on the inner wall of the loading chamber, the water collecting structure is arranged in the loading chamber, the dehumidification component is configured with a first cooling flow path, the condensation plate and the first cooling flow path are connected and arranged, the first cooling flow path is suitable for circulating a cooling medium toward the condensation plate to reduce the temperature of the condensation plate by heat exchange, and the water collecting structure is used to collect and discharge condensed water on the condensation plate; the control system is electrically connected to the humidity sensor, and the control system is electrically connected to the dehumidifier; the control system is used to control the operation of the dehumidifier according to the humidity data.

[0030] The dehumidification container system of this structure places the battery system in the loading chamber of the container, and the humidity data of the loading chamber is monitored in real time by a humidity sensor. After the humidity data reaches the data required for dehumidification, the control system controls the operation of the dehumidifier. On the one hand, the gas in the loading chamber is circulated through the second air inlet and the second air outlet of the dehumidifier to dehumidify the airflow entering the dehumidifier. On the other hand, the first cooling flow path configured by the dehumidification component circulates the cooling medium toward the condensation plate, so that the moisture of the gas in the loading chamber condenses on the condensation plate. After gathering into water droplets, the condensed water on the condensation plate is discharged through the water collection structure. When the dehumidifier is in operation, the gas in the loading chamber can circulate and contact with the condensation plate, thereby accelerating the condensation of moisture in the gas in the loading chamber. In this way, the dehumidification capacity is large and the dehumidification efficiency is high, which ensures that the battery system is in a working environment with reasonable humidity, thereby improving the safety and working stability of the energy storage equipment.

[0031] 2. The dehumidification container system provided by the present invention, the dehumidification component also includes a second cooling flow path, a compressor, a condensation component and a fan component. Along the flow direction of the second cooling flow path, the compressor and the condensation component are arranged in communication, the condensation component and the fan component are installed in the dehumidifier, the condensation component and the fan component are arranged in the connecting area between the second air inlet and the second air outlet, and the fan component is used to direct air toward the condensation component.

[0055] Example

[0056] like Figures 1 to 7 As shown, this embodiment provides a dehumidification container system, including a container 1, a dehumidification component, a condensation component and a control system. The container 1 has a loading cavity, and the loading cavity is suitable for placing a battery system 2.

[0057] In this embodiment, if Figure 1 and Figure 2 As shown, the dehumidification component includes a humidity sensor 41 and a dehumidifier 42. The humidity sensor 41 is installed in the loading chamber to monitor the humidity data of the loading chamber. The dehumidifier 42 is installed on the container 1. The dehumidifier 42 has a second air inlet 422 and a second air outlet 423 connected to the loading chamber.

[0058] In this embodiment, if Figure 2As shown, the condensation component includes a condensation plate 51 and a water collecting structure 52. The condensation plate 51 is installed on the inner wall of the loading chamber, and the water collecting structure 52 is arranged in the loading chamber. The dehumidification component is equipped with a first cooling flow path 401. The condensation plate 51 and the first cooling flow path 401 are connected and arranged. The first cooling flow path 401 is suitable for circulating a cooling medium toward the condensation plate 51 to reduce the temperature of the condensation plate 51 by heat exchange. The water collecting structure 52 is used to collect and discharge condensed water on the condensation plate 51; the control system is electrically connected to the humidity sensor 41, and the control system is electrically connected to the dehumidifier 42; the control system is used to control the operation of the dehumidifier 42 according to the humidity data.

[0059] The dehumidification container system provided in this embodiment places the battery system 2 in the loading chamber of the container 1, and the humidity sensor 41 monitors the humidity data of the loading chamber in real time. After the humidity data reaches the data required for dehumidification, the control system controls the dehumidifier 42 to operate. On the one hand, the gas in the loading chamber is circulated through the second air inlet 422 and the second air outlet 423 of the dehumidifier 42 to dehumidify the airflow entering the dehumidifier 42. On the other hand, the first cooling flow path 401 configured by the dehumidification component circulates the cooling medium toward the condensation plate 51, so that the moisture of the gas in the loading chamber condenses on the condensation plate 51. After it gathers into water droplets, the condensed water on the condensation plate 51 is discharged through the water collecting structure 52. During the working stage, the dehumidifier 42 can make the gas in the loading chamber circulate and contact with the condensation plate 51, so as to accelerate the condensation of the moisture of the gas in the loading chamber. In this way, the dehumidification capacity is large and the dehumidification efficiency is high, which ensures that the battery system 2 is in a working environment with a reasonable humidity, thereby improving the safety and working stability of the energy storage equipment.

[0060] For the structural design embodiment of the container 1:

[0061] For example, in some embodiments, Figure 1 and Figure 2 As shown, the container 1 is provided with a first air inlet 11 and a first air outlet 12 which are connected to the loading chamber, the first air inlet 11 and the first air outlet 12 are arranged at intervals, and the container 1 is provided with a door 13 which is rotatably arranged on the container 1, and the container 1 is opened through the door 13 to install and remove the battery system 2. In other embodiments, a plurality of doors 13 are provided, and some of the doors 13 may be fixed to the container 1 by welding or bolts.

[0062] For example, in some embodiments, Figure 3 As shown, a water vapor barrier assembly is installed at the first air inlet 11, and the water vapor barrier assembly is used to isolate external water vapor from entering the loading chamber. The water vapor barrier assembly blocks the water vapor entering the airflow of the loading chamber, maintains the dryness of the loading chamber, and reduces the humidity.

[0063] For example, in some embodiments, Figure 3As shown, a guide member 15 is installed at the first air inlet 11, and the guide member 15 is used to guide the outside air to the loading chamber. The outside airflow is introduced into the loading chamber through the guide member 15, and the water vapor barrier component is used to block the water vapor to ensure the dry environment of the loading chamber.

[0064] As a preferred embodiment, Figure 3 As shown, the water vapor barrier assembly includes a filter screen 141, a waterproof breathable membrane 142 and a barrier screen 143 arranged in sequence along the air inlet direction of the first air inlet 11. The waterproof breathable membrane 142 is used to isolate water vapor in the external atmosphere input into the loading chamber through the first air inlet 11.

[0065] For example, in some embodiments, Figure 3 As shown, the container 1 is constructed with a drainage hole 144, which is arranged at the bottom of the water vapor barrier assembly to collect the blocked moisture.

[0066] For example, in some embodiments, Figure 3 As shown, the first air inlet 11 is installed with a fixed seal having a fixed frame 16 , the water vapor barrier assembly is installed in the fixed frame 16 , and the drainage hole 144 is specifically structured and formed on the fixed frame 16 .

[0067] The outermost layer is designed with a filter 141 to prevent foreign objects and impurities from entering the loading chamber. A waterproof and breathable membrane 142 is arranged on the inner side of the filter 141, and a barrier net 143 is arranged behind the waterproof and breathable membrane 142. When the drainage member 15 is started, the outside air passes through the filter 141, the waterproof and breathable membrane 142, and the barrier net 143 and enters the container 1. The waterproof and breathable membrane 142 only allows air to enter, and moisture is blocked. The generated water will flow out through the drainage hole 144.

[0068] Through the above-mentioned technical solution, the water vapor barrier component configured at the first air inlet 11 can prevent humid air from entering the loading chamber. It is specifically designed with a waterproof and breathable membrane 142. The gas entering the interior is directly converted into dry air after moisture filtration, and the dry air can be actively driven to enter and replace the fluid inside the loading chamber.

[0069] In the dehumidification container system provided in this embodiment, the air outlet of the container 1, the condensation plate 51 and the dehumidifier 42 work together to control the humidity inside the container 1 and reduce the risk of moisture condensation on electrical components.

[0070] For example, in some embodiments, Figure 1 and Figure 5 As shown, the control system is provided with an electric control box 61 , which can be arranged at the bottom of the battery system 2 , and the electric control box 61 is provided with a plurality of electrical interfaces to establish an electrical connection path.

[0071] As a preferred embodiment, Figure 1 and Figure 2 As shown, the dehumidifier 42 and the condensation plate 51 are arranged at intervals, the second air inlet 422 and the second air outlet 423 are arranged on the area of ​​the first inner wall surface of the container 1, the condensation plate 51 is arranged on the area of ​​the second inner wall surface of the container 1, and the first inner wall surface and the second inner wall surface are arranged adjacent to each other or facing each other.

[0072] For example, in some embodiments, the first air inlet 11 and the first air outlet 12 are respectively located at diagonally opposite corners of the container 1 to ensure that the two are at the farthest distance. The first air inlet 11 and the first air outlet 12 can be used as a passage path for a fire vent.

[0073] For the structural design example of the dehumidification component:

[0074] In a specific implementation, such as Figure 5 As shown, the dehumidification component also includes a second cooling flow path 402, a compressor 427, a condensation member 43 and a fan member 44. Along the flow direction of the second cooling flow path 402, the compressor 427 is connected to the condensation member 43. The condensation member 43 and the fan member 44 are installed in the dehumidifier 42. The condensation member 43 and the fan member 44 are arranged in the communication area between the second air inlet 422 and the second air outlet 423. The fan member 44 is used to guide the air toward the condensation member 43. In this arrangement, the dehumidifier 42 can specifically use the condensation method to condense and dehumidify the gas flowing therein. The second cooling flow path 402 transports the cooling medium to flow to the condensation member 43. The fan member 44 is used as a driving source to introduce the airflow from the second air inlet 422, flow toward the condensation member 43, and flow out from the second air outlet 423. The airflow condenses into dew on the condensation member 43. The dehumidifier 42 is connected to the loading chamber to exchange airflow, and the dehumidifier 42 is used to condense and dehumidify, so as to achieve the purpose of reducing the humidity in the loading chamber.

[0075] For example, in some embodiments, Figure 5 As shown, the dehumidification component further includes a PTC heater 45, which is installed in the dehumidifier 42. The PTC heater 45 is electrically connected to the control system and is used to heat the gas in the dehumidifier 42. In this configuration, the PTC heater 45 is used to increase the dew point temperature of the airflow in the dehumidifier 42, and accelerate the condensation of moisture in the airflow circulating in the dehumidifier 42. Since the dehumidifier 42 exchanges airflow with the loading chamber, the temperature in the loading chamber can be increased accordingly, so as to reduce the dew point of the humid air in the loading chamber, so that the humid air can be more easily condensed on the condensation plate 51, thereby optimizing the dehumidification capacity of the system and improving the dehumidification efficiency.

[0076] In a specific embodiment, Figure 5As shown, the dehumidification assembly also includes a liquid storage 46, a dryer 47, an expansion valve 48, a three-way valve 49 and a heat exchanger 410 which are sequentially connected to the condensing element 43 along the flow direction of the second cooling flow path 402, and the output side of the heat exchanger 410 is connected to the input side of the compressor 427. The above-mentioned flow devices distributed along the second cooling flow path 402 can be centrally assembled in the dehumidifier 42 to enhance the compact design of the structure.

[0077] In a specific embodiment, Figure 5 As shown, the heat exchanger 410 includes a first heat exchange flow path and a second heat exchange flow path, the first heat exchange flow path is connected to the first cooling flow path 401, and the second heat exchange flow path is connected to the second cooling flow path 402; a drainage pump 412 is provided on the first cooling flow path 401. The drainage pump 412 transports the condensed working medium to the condensation plate 51.

[0078] In a specific embodiment, Figure 5 As shown, the three-way valve 49 is configured as a one-inlet and two-outlet valve, and the dehumidification component also includes an evaporator 411. The evaporator 411 and the heat exchanger 410 are arranged in parallel on the second cooling flow path 402 through the three-way valve 49, and the output side of the evaporator 411 is connected to the input side of the compressor 427.

[0079] Through the above technical solution, by controlling the start-up of the dehumidifier 42, the working fluid inside the compressor 427 will enter the condenser, flow through the liquid storage tank 46, and pass through the dryer 47 and the expansion valve 48 in turn. When the three-way valve 49 is in the position, it enters the evaporator 411 and finally enters the compressor 427. The evaporator 411 can be located at the inlet position of the dehumidifier 42, and the condenser is located at the outlet position of the dehumidifier 42. When the humid air enters the condenser dehumidifier 42, it will condense in the condenser with a lower temperature.

[0080] As a preferred embodiment, Figure 4 As shown, the dehumidifier 42 includes a housing 421, a second air inlet 422 is arranged in the lower area of ​​the housing 421, and a second air outlet 423 is arranged in the upper area of ​​the housing 421. This arrangement can establish a bottom-in-top-out circulation mode, which is conducive to capturing humid air with higher density.

[0081] As a preferred embodiment, Figure 5 As shown, the dehumidifier 42 is provided with two or more fixing positions 424 , and the fixing positions 424 are fixedly connected to the container 1 .

[0082] Through the above technical solution, the dehumidifier 42 is fixed inside the container 1 through the fixing position 424. When the dehumidifier 42 is in working state, viewed from the front of the dehumidifier 42, the bottom is the air inlet of the dehumidifier 42, and the top is the air outlet of the dehumidifier 42, thereby forming a circulating wind in the container 1, and the humid air enters the interior of the dehumidifier 42, and the dry air enters the container 1 from the second air outlet 423 of the dehumidifier 42, thereby forming a dehumidification effect, and the second medium inlet 425 and the second medium outlet 426 of the dehumidifier 42 are connected to the condensation plate 51 to form a liquid cooling cycle.

[0083] For the structural design embodiment of the condensation plate 51:

[0084] For example, in some embodiments, Figure 2 As shown, one or more condensation plates 51 are provided, and the condensation plates 51 are arranged on the inner wall of the loading chamber at intervals, and two adjacent condensation plates 51 are arranged at intervals. In a specific embodiment, the cooling medium of the first cooling flow path 401 can be distributed to each condensation plate 51 by a distributor (not shown in the figure).

[0085] For example, in some embodiments, Figure 6 As shown, the condensation plate 51 is provided with a first medium inlet 511 and a first medium outlet 512, and a medium flow channel 513 is provided inside the condensation plate 51. The medium flow channel 513 is connected and arranged between the first medium inlet 511 and the first medium outlet 512, and the condensation component also includes an inlet and outlet pipe 53; the dehumidifier 42 is provided with a second medium inlet 425 and a second medium outlet 426, and the first medium inlet 511 and the second medium outlet 426, and the second medium inlet 425 and the first medium outlet 512 are connected and arranged through the inlet and outlet pipe 53. The cooling medium will flow through the medium flow channels 513 on each condensation plate 51, so that the wet air in the loading chamber that contacts the condensation plate 51 will condense, and then the condensed water will be collected and discharged through the water collection structure 52.

[0086] For example, in some embodiments, Figure 6 As shown, one or more medium nozzles 514 are provided on the condensation plate 51, and the medium nozzles 514 are connected to the first cooling flow path 401. With this arrangement, the condensation plate 51 can be used as a means of fire extinguishing. When a fire occurs inside, water will be sprayed out, thereby achieving the function of auxiliary fire extinguishing.

[0087] For example, in some embodiments, Figure 6 and Figure 7As shown, the condensation plate 51 is configured as a plate structure, and at least one side of the plate structure is provided with a plurality of spoiler packages arranged at intervals and protruding from the wall surface of the plate structure. Specifically, a plurality of first spoiler packages 515 are provided on one side of the condensation plate 51, and a plurality of second spoiler packages 516 are provided on the other side of the condensation plate 51. Through the design of the spoiler packages, the heat exchange area between the condensation plate 51 and the humid air in the loading chamber is increased, so as to achieve a rapid dehumidification effect and improve the dehumidification efficiency.

[0088] For example, in some embodiments, the condensation plate 51 is vertically arranged along the height plane, and the water collection structure 52 is arranged in the direction extending from the lower part of the condensation plate 51. The condensation plate 51 is placed vertically, and when condensation occurs, water can quickly drip into the water collection structure 52 due to gravity.

[0089] For example, in some embodiments, the water collecting structure 52 is configured as a guide groove, which has an inclination angle of 5-10° with the horizontal plane; the condensed water dehumidified by the condensation plate 51 can flow out of the container 1 through the guide groove, and the guide groove has an inclination angle, so that the condensed water can flow out of the container 1 smoothly to prevent water accumulation inside. In a specific embodiment, the guide groove is assembled and arranged on the bottom wall of the container.

[0090] As a further embodiment, Figure 1 As shown, the dehumidification container system also includes a liquid cooling system, which includes a liquid cooling unit 31 and a liquid cooling plate 32. The liquid cooling unit 31 and the liquid cooling plate 32 are connected through a pipeline, and the liquid cooling unit 31 is electrically connected to the control system. The liquid cooling plate 32 is arranged at the bottom of the battery system 2.

[0091] In the dehumidification container system provided in this embodiment, the liquid cooling system, dehumidification components and condensation components inside the container 1 can work together to cause condensation on the liquid cooling plate 32 and the condensation plate 51 respectively, making full use of the cold source to condense the moisture inside the loading chamber into water, thereby achieving the purpose of dehumidification; when the system humidity is high, the air outlet, liquid cooling plate 32, dehumidifier 42 and condensation plate 51 of the container 1 work together to control the humidity inside the container 1, reduce the risk of moisture condensation on electrical components, and improve the safety and working stability of the energy storage equipment.

[0092] Through the above technical solution, the system achieves the effect of reducing humidity by dehumidifying in advance, ensuring an internal environment, so that the system can operate safely; the system can perform dehumidification logic with different strategies according to the internal humidity to achieve the effect of rapid dehumidification; when the system is dehumidifying, fresh air from the outside can enter the loading chamber, causing turbulence inside the container 1, the air flows, and the humid air in different areas can encounter the condensation plate 51 to condense, thereby achieving the dehumidification effect.

[0093] The dehumidification container system provided in this embodiment has the following control strategies for different humidity ranges:

[0094] When the humidity sensor 41 detects that the humidity in the loading chamber is greater than or equal to 65, the information will be transmitted to the electric control box 61, and the electric control box 61 will control the startup and operation parameters of the dehumidifier 42. The working fluid in the compressor 427 will enter the condenser along the second cooling flow path 402, flow through the liquid storage tank 46, and pass through the dryer 47 and the expansion valve 48 in turn. When the three-way valve 49 is in the position, it enters the evaporator 411 and finally enters the compressor 427. The evaporator 411 is located at the inlet position of the dehumidifier 42, and the condenser is located at the outlet position of the dehumidifier 42. When the humid air enters the dehumidifier 42, it will condense in the condenser with a lower temperature. The air is heated after passing through the condenser, and the humid air in the container 1 is reduced. As the temperature increases, the dew point temperature also decreases.

[0095] When the humidity sensor 41 detects that the humidity is greater than or equal to 75, the PTC heater 45 is started during the operation of the dehumidifier 42 to heat the air flow, so that the temperature inside the container 1 increases and the dew point temperature decreases.

[0096] When the humidity sensor 41 detects that the humidity is greater than or equal to 85, the working fluid inside the compressor 427 will enter the heat exchanger 410. At this time, the cooling working fluid inside the condensation plate 51 will also be driven by the drainage pump 412 to start flowing along the first cooling flow path 401. The cooling working fluid inside the condensation plate 51 on the first cooling flow path 401 and the cooling working fluid of the compressor 427 on the second cooling flow path 402 exchange heat in the heat exchanger 410. The cooling working fluid on the first cooling flow path 401 becomes a low-temperature liquid, which flows through the condensation plate 51, thereby reducing the temperature of the condensation plate 51. At this time, the fans at the air inlet and outlet of the container 1 will be started, and the fan inside the container 1 will flow. The humid air will condense into water when it encounters the condensation plate 51, and finally drip into the guide groove, thereby reducing the internal humidity and achieving the dehumidification effect.

[0097] When the humidity sensor 41 detects that the humidity is greater than or equal to 95, it has seriously affected the operation of the system. At this time, the liquid cooling unit 31 will also start, and the refrigeration temperature is adjusted to 5 to 15 degrees. Then, it passes through the liquid cooling pipe and enters the liquid cooling plate 32. Due to the relatively low temperature, condensation will be generated at the bottom of the cold plate, thereby reducing the internal moisture and achieving a rapid dehumidification effect without affecting the operation of the system.

[0098] The dehumidification container system provided in this embodiment can adjust and control the humidity inside the container 1. When the humidity inside the container 1 reaches the set range, the system will automatically monitor and identify to control the dehumidification component to work, and start different dehumidification strategies according to the humidity data to reduce the humidity inside the system.

[0099] The dehumidification container system provided in this embodiment can start dehumidification logic of different strategies for different humidity ranges according to the humidity inside the system, so as to achieve the effect of early dehumidification and rapid dehumidification.

[0100] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
