[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] This utility model embodiment provides a dehumidification device. This dehumidification device is applied to a battery pack to dehumidify the air inside the battery pack. The heat recovery module in this embodiment recovers and utilizes the heat energy obtained when the heat exchange module exchanges heat with the exhaust gas during the regeneration of the adsorption rotor module. This heat energy is then used to generate electricity, which helps reduce energy loss during the dehumidification process and improves energy utilization. Figure 1 This is a schematic diagram of a dehumidification device provided in an embodiment of this utility model. (Refer to...) Figure 1 The dehumidification device includes: a sensing module 110, a control module 120, a power supply module 130, an adsorption wheel module 140, a heat exchange module 150, and a heat recovery module 160.

[0037] A sensing module 110 is disposed within the battery pack 10 and is connected to a control module 120, which is also connected to a power supply module 130. An adsorption wheel module 140 is connected to the power supply module 130 and the battery pack 10, forming an air circulation loop. The adsorption wheel module 140 is also connected to a heat exchange module 150, which is further connected to a heat recovery module 160, which is connected to an external device 20. The sensing module 110 detects the humidity within the battery pack 10. The control module 120 controls whether the power supply module 130 supplies power to the adsorption wheel module 140 based on the humidity detected by the sensing module 110. The adsorption wheel module 140 dehumidifies the battery pack 10. The heat exchange module 150 exchanges heat with the exhaust gas generated during the regeneration of the adsorption wheel module 140. The heat recovery module 160 uses the heat energy from the heat exchange module 150 to generate electricity.

[0038] Specifically, the sensing module 110 is disposed inside the battery pack 10, and the sensing module 110 detects the humidity of the air inside the battery pack 10. For example, the sensing module 110 can be a humidity sensor. The control module 120 acquires the humidity detected by the sensing module 110 and controls the output of the power supply module 130 based on the humidity detected by the sensing module 110, thereby controlling the start and stop of the adsorption wheel module 140.

[0039] When the humidity detected by the sensing module 110 is greater than or equal to the preset humidity, the control module 120 generates a power supply command; when the humidity detected by the sensing module 110 is less than the preset humidity, the control module 120 generates a power-off command. The power supply module 130 acquires the power supply or power-off command generated by the control module 120 and supplies or stops supplying power to the adsorption wheel module 140 according to the power supply or power-off command. The battery management system of the battery pack 10 can be reused as the control module 120 to reduce the cost of the dehumidifier. In practical applications, the control module 120 can also be set as a separate controller according to actual needs.

[0040] When the power supply module 130 supplies power to the adsorption wheel module 140, the adsorption wheel module 140 draws air from inside the battery pack 10, allowing the air inside the battery pack 10 to enter the adsorption wheel module 140. When the air enters the adsorption wheel module 140, the adsorption wheel module 140 adsorbs moisture in the air, thus dehumidifying the air. The dehumidified air then returns to the battery pack 10. Under the action of the adsorption wheel module 140, the air inside the battery pack 10 circulates between the adsorption wheel module 140 and the battery pack 10. Moisture in the air inside the battery pack 10 is continuously adsorbed by the adsorption wheel module 140 during this circulation, thereby achieving dehumidification of the battery pack 10.

[0041] While dehumidifying the air inside the battery pack 10, the adsorption rotor module 140 also undergoes heating and regeneration, expelling the adsorbed water vapor through hot air. The exhaust gas (hot air containing water vapor) discharged from the adsorption rotor module 140 flows into the heat exchange module 150. The heat exchange module 150 exchanges heat with the exhaust gas discharged from the adsorption rotor module 140 and transfers the heat energy obtained to the heat recovery module 160. The heat recovery module 160 uses the heat energy of the exhaust gas discharged from the adsorption rotor module 140 to generate electricity and supply power to the external device 20. For example, the heat recovery module 160 can be a thermoelectric generator.

[0042] It should be noted that the battery pack 10 is connected to the adsorption wheel module 140 via a pipeline, and the adsorption wheel module 140 is connected to the heat exchange module 150 via a pipeline.

[0043] In this embodiment of the invention, the sensing module 110 detects the humidity inside the battery pack 10. The control module, based on the humidity detected by the sensing module 110, controls the power supply module 130 to supply power to the adsorption wheel module 140. The adsorption wheel module 140 dehumidifies the battery pack 10. The heat exchange module 150 exchanges heat with the exhaust gas discharged from the adsorption wheel module 140 and transfers the obtained heat energy to the heat recovery module 160. The heat recovery module 160 uses the heat energy from the exhaust gas discharged from the adsorption wheel module 140 to generate electricity and supply power to the external device 20. The heat recovery module 160 of this embodiment recovers and utilizes the heat energy obtained by the heat exchange module 150 during the regeneration of the adsorption wheel module 140, and uses this heat energy to generate electricity, which helps reduce energy loss during the dehumidification process and improves energy utilization.

[0044] Figure 2 This is a schematic diagram of another dehumidification device provided in this embodiment of the present invention. Optionally, the heat recovery module 160 can also be connected to the battery pack 10 and the adsorption wheel module 140 respectively. In practical applications, the electrical energy generated by the heat recovery module 160 can also be used to power the electronic devices in the battery pack 10, or it can also be used to charge the battery pack 10. During the operation of the adsorption wheel module 140, the adsorption wheel module 140 generates a certain amount of heat. Therefore, the heat recovery module 160 can also recover the heat generated by the adsorption wheel module 140 to further improve the energy utilization rate of the dehumidification device.

[0045] Figure 3 This is a schematic diagram of another dehumidification device provided in an embodiment of the present utility model. Optionally, based on the above embodiments, refer to... Figure 3The adsorption rotor module 140 includes: an adsorption rotor 141, a dehumidifying fan 142, a heater 143, and a regeneration fan 144.

[0046] The dehumidification input of the adsorption rotor 141 is connected to the battery pack 10, the dehumidification output of the adsorption rotor 141 is connected to the input of the dehumidifying fan 142, the output of the dehumidifying fan 142 is connected to the battery pack 10, the input of the regeneration fan 144 is connected to outside air, the output of the regeneration fan 144 is connected to the input of the heater 143, the output of the heater 143 is connected to the regeneration input of the adsorption rotor 141, and the regeneration output of the adsorption rotor 141 is connected to the heat exchange module 150. The dehumidifying fan 142 is used to drive the air in the battery pack 10 to circulate between the battery pack 10 and the adsorption rotor 141. The adsorption rotor 141 is used to dehumidify the air in the battery pack 10. The regeneration fan 144 is used to drive outside air into the heater 143 and the adsorption rotor 141. The heater 143 is used to heat the outside air to regenerate the adsorption rotor 141.

[0047] Specifically, when the adsorption wheel module 140 is powered on, the dehumidifying fan 142 draws or blows air to circulate the air inside the battery pack 10 between the battery pack 10 and the adsorption wheel 141. When the air inside the battery pack 10 enters the adsorption wheel 141, the adsorption wheel 141 adsorbs the moisture in the air, thereby dehumidifying the air. The air dehumidified by the adsorption wheel 141 returns to the battery pack 10 through the dehumidifying fan 142.

[0048] When the adsorption rotor 141 dehumidifies the air inside the battery pack 10, outside air enters the heater 143 driven by the regeneration fan 144, and the heater 143 heats the outside air. The hot air then passes through the adsorption rotor 141 driven by the regeneration fan 144. The adsorption rotor 141 discharges the adsorbed water vapor through the hot air, and the adsorption rotor 141 is re-dried under the action of the hot air, thus achieving regeneration of the adsorption rotor 141. The exhaust gas (hot air containing water vapor) discharged from the adsorption rotor 141 flows into the heat exchange module 150. The heat exchange module 150 exchanges heat with the exhaust gas discharged from the adsorption rotor module 140 and transfers the heat energy obtained to the heat recovery module 160. The heat recovery module 160 uses the heat energy of the exhaust gas discharged from the adsorption rotor module 140 to generate electricity and supply power to the external device 20.

[0049] Figure 4 This is a schematic diagram of another dehumidification device provided in an embodiment of the present utility model. Optionally, based on the above embodiments, refer to... Figure 4 The adsorption rotor module 140 also includes a dehumidifying filter 145 and a regeneration filter 146.

[0050] The input end of the dehumidifier filter 145 is connected to the battery pack 10, and the output end of the dehumidifier filter 145 is connected to the adsorption rotor 141. The input end of the regeneration filter 146 is connected to the outside air, and the output end of the regeneration filter 146 is connected to the regeneration fan 144. The dehumidifier filter 145 is used to filter the air inside the battery pack 10, and the regeneration filter 146 is used to filter the outside air. The dehumidifier filter 145 and the regeneration filter 146 filter the air entering the adsorption rotor 141 to prevent impurities in the air from being adsorbed onto the rotor 141, thus helping to avoid damage to the adsorption rotor 141.

[0051] Based on the above embodiments, optionally, the heat exchange module 150 may include: a duct, a heat exchanger, and a water collection pipe. The duct is connected to the adsorption rotor module 140, and both the heat exchanger and the water collection pipe are disposed within the duct, with the water collection pipe located below the heat exchanger. The heat exchanger is connected to the heat recovery module 160. The duct guides the waste gas from the regeneration of the adsorption rotor module 140 to the heat exchanger, where the heat exchanger exchanges heat with the waste gas and transfers the heat energy obtained to the heat recovery module 160. During heat exchange, since water vapor exists in the waste gas, it condenses into water droplets during the heat exchange process. The water collection pipe collects and discharges the condensate generated during the heat exchange process.

Specifically, photovoltaic power generation device 131 converts light energy into electrical energy, and wind power generation device 131 converts wind energy into electrical energy. It should be noted that both photovoltaic power generation device 131 and wind power generation device 132 can be equipped with energy storage components to store electrical energy.
