[0024] Hereinafter, embodiments will be described with reference to the accompanying drawings, which do not limit the disclosure described in the claims in any way.

[0025] See also Figure 1 and Figure 2 , the following combination Figure 1 and Figure 2 A dehumidification device provided in an embodiment of the present application is described in detail.

[0026] The present application embodiment provides a dehumidification device, such as Figure 1 and Figure 2 As shown, the dehumidification device includes a dehumidification box body 1 and a dehumidification component 2 arranged in the dehumidification box body 1.

[0027] Among them, the dehumidification component 2 includes a dehumidification mechanism 21 and a first dehumidification fan 22. The air outlet of the first dehumidification fan 22 is arranged toward the dehumidification mechanism 21. The first dehumidification fan 22 is used to inhale the gas to be dehumidified in the battery compartment and transmit the gas to be dehumidified to the dehumidification mechanism 21 so that the dehumidification mechanism 21 absorbs moisture in the gas to be dehumidified. A first exhaust port 11 is provided on the dehumidification box 1, and the gas to be dehumidified with moisture removed flows back into the battery compartment from the first exhaust port 11.

[0028] In an embodiment of the present application, the dehumidification component 2 is used to remove the gas to be dehumidified in the battery compartment, wherein the gas to be dehumidified in the battery compartment may be the humid air in the battery compartment. Then, by dehumidifying the humid air in the battery compartment, condensation on the battery surface due to excessive humidity in the battery compartment can be avoided.

[0029] In some specific embodiments, Figure 1 and Figure 2 As shown, the dehumidification component 2 includes a dehumidification mechanism 21 and a first dehumidification fan 22, wherein the first dehumidification fan 22 can suck out the gas to be dehumidified in the battery compartment and output it toward the dehumidification mechanism 21, and then the dehumidification mechanism 21 can be used to absorb moisture in the gas to be dehumidified to remove the moisture in the gas to be dehumidified to obtain dry gas, so that the dry gas can flow back into the battery compartment through the first exhaust port 11 on the dehumidification box 1, so as to achieve dehumidification of the humid gas in the battery compartment while ensuring that the pressure in the battery compartment remains unchanged.

[0030] It should be noted that if Figure 1 and Figure 2 As shown, the dehumidification box body 1 is also provided with a first air inlet 13, wherein the first air inlet 13 is arranged on the side wall of the dehumidification box body 1, and the air inlet port of the first dehumidification fan 22 faces the first air inlet 13, so that the first dehumidification fan 22 inhales the humid gas in the battery compartment from the first air inlet 13.

[0031] In an optional embodiment, the dehumidification mechanism 21 includes a rotatable dehumidification component 213 , and the rotation direction of the dehumidification component 213 intersects with the direction in which the gas to be dehumidified is output from the air outlet of the first dehumidification fan 22 .

[0032] In an embodiment of the present application, the dehumidification mechanism 21 can be a dehumidification wheel. In some specific embodiments, the dehumidification mechanism 21 includes a ceramic fiber carrier and a rotatable dehumidification component 213, wherein the dehumidification component 213 is arranged on the ceramic fiber carrier, the dehumidification component 213 can rotate with the ceramic fiber carrier, and the dehumidification component 213 is exposed to the outside so that the dehumidification component 213 can absorb moisture in the gas to be dehumidified. It should be noted that the dehumidification component 213 can be a dehumidifier that can absorb moisture but does not change the direction of gas flow.

[0033] In some specific embodiments, the rotation direction of the dehumidifying element 213 intersects with the direction in which the gas to be dehumidified is output from the air outlet of the first dehumidifying fan 22, thereby ensuring that the first dehumidifying fan 22 transmits the gas to be dehumidified to the dehumidifying element 213 to remove moisture from the gas to be dehumidified. Figure 1 and Figure 2 As shown, the rotation direction of the dehumidification element 213 is perpendicular to the direction in which the gas to be dehumidified is output from the air outlet of the first dehumidification fan 22, thereby improving the dehumidification effect of the dehumidification element 213 on the gas to be dehumidified output from the air outlet of the first dehumidification fan 22.

[0034] In an optional embodiment, if Figure 2 As shown, the dehumidification mechanism 21 includes a dehumidification zone 211 and a regeneration zone 212 , both of which are provided with dehumidification components 213 , the air outlet of the first dehumidification fan 22 is arranged toward the dehumidification zone 211 , and the regeneration zone 212 is arranged adjacent to the dehumidification zone 211 .

[0035] In an embodiment of the present application, the air outlet of the first dehumidification fan 22 is arranged toward the middle of the dehumidification zone 211, so as to utilize the dehumidification element 213 in the dehumidification zone 211 to dehumidify the gas to be dehumidified output by the first dehumidification fan 22, thereby improving the dehumidification effect of the gas to be dehumidified.

[0036] In actual applications, after the dehumidification element 213 in the dehumidification zone 211 dehumidifies the gas to be dehumidified output by the first dehumidification fan 22, the dehumidification element 213 in the dehumidification zone 211 can be rotated to the regeneration zone 212 so that the moisture absorbed in the dehumidification element 213 can be evaporated in the regeneration zone 212. The dehumidification element 213 after the moisture is evaporated can dehumidify the gas to be dehumidified again to achieve cyclic dehumidification.

[0037] It should be noted that when the dehumidification element 213 in the dehumidification zone 211 rotates to the regeneration zone 212, the dehumidification element 213 in the regeneration zone 212 can rotate to the dehumidification zone 211, thereby continuously dehumidifying the gas to be dehumidified to improve the dehumidification efficiency.

[0038] In one specific embodiment, the rotatable dehumidifying element 213 can rotate 10 to 40 times per hour.

[0039] In an optional embodiment, the dehumidification component 2 also includes a second dehumidification fan 23, and the air outlet of the second dehumidification fan 23 is arranged toward the regeneration zone 212 in the dehumidification mechanism 21. The second dehumidification fan 23 is used to inhale the dehumidified gas outside the battery compartment and transfer the dehumidified gas to the regeneration zone 212, so that the dehumidified gas removes moisture in the regeneration zone 212.

[0040] In an embodiment of the present application, the dehumidified gas can be the air outside the battery compartment. The air outside the battery compartment can be sucked in by the second dehumidification fan 23 and output toward the regeneration zone 212 in the dehumidification mechanism 21. The dehumidified gas can then be used to evaporate the moisture absorbed in the dehumidification component 213 that rotates to the regeneration zone 212, so as to dry the dehumidification component 213 that absorbs moisture. Thus, the dried dehumidification component 213 can be rotated back to the dehumidification zone 211, and the dehumidified gas can be repeatedly dehumidified to improve the dehumidification efficiency.

[0041] In an optional embodiment, if Figure 1 and Figure 2 As shown, the dehumidification box body 1 is provided with a second air outlet 12, and the dehumidified gas that removes moisture in the regeneration area 212 flows back to the outside of the battery compartment from the second air outlet 12.

[0042] Specifically, after the dehumidified gas is used to remove the moisture in the dehumidification element 213 in the regeneration zone 212, it can flow back to the outside of the battery compartment through the second exhaust port 12, so as to dry the moisture absorbed by the dehumidification element 213 while ensuring that the pressure in the dehumidification box 1 remains unchanged. Then, the dehumidification element 213 in the regeneration zone 212 can be rotated to the dehumidification zone 211, thereby realizing cyclic dehumidification.

[0043] It should be noted that if Figure 1 and Figure 2 As shown, the dehumidification box body 1 is also provided with a second air inlet 14, wherein the second air inlet 14 is arranged on the side wall of the dehumidification box body 1, and the air inlet port of the second dehumidification fan 23 faces the second air inlet 14, so that the second dehumidification fan 23 inhales air outside the battery compartment from the second air inlet 14.

Furthermore, through the layout of the first air inlet 13, the second air inlet 14, the first air outlet 11 and the second air outlet 12 as above, the winds in different directions can be prevented from interfering with each other, thereby further improving the dehumidification effect.

[0045] In an optional embodiment, the first dehumidification fan 22 and the second dehumidification fan 23 are respectively located on both sides of the dehumidification mechanism 21, and the direction of the air outlet of the first dehumidification fan 22 is opposite to the direction of the air outlet of the second dehumidification fan 23.

[0046] Specifically, the layout of the first dehumidification fan 22, the second dehumidification fan 23 and the dehumidification mechanism 21 can be seen in Figure 1 and Figure 2 Furthermore, by arranging the first dehumidification fan 22 and the second dehumidification fan 23 on both sides of the dehumidification mechanism 21, the dehumidification effect is improved.

[0047] In an optional embodiment, the dehumidification component 2 further includes a heat sink 24, which is disposed between the second dehumidification fan 23 and the dehumidification mechanism 21, and is used to heat the dehumidified gas.

[0048] Specifically, the heat sink 24 can be a radiator, and the heat sink 24 is arranged between the second dehumidification fan 23 and the dehumidification mechanism 21 so that the heat dissipated by the heat sink 24 can be used to heat the dehumidified gas, thereby accelerating the dehumidification of the moisture in the dehumidification element 213 and improving the dehumidification effect.

[0049] In an optional embodiment, the heat sink 24 includes a first end and a second end, the first end is used to connect to the compressor 3, and the second end is used to connect to the condenser 4, the compressor 3 is used to output gas of a preset temperature to the heat sink 24, and the gas of the preset temperature is used to heat the dehumidified gas in the heat sink 24.

[0050] In the embodiment of the present application, the compressor 3 is used to provide heat to the heat sink 24. Specifically, the gas of preset temperature output by the compressor 3 can heat the dehumidified gas in the heat sink 24, so that the temperature of the dehumidified gas can be increased after passing through the heat sink 24. The heated dehumidified gas can improve the efficiency of dehumidifying the moisture in the dehumidification element 213, thereby helping to improve the dehumidification effect.

[0051] It should be noted that the compressor 3 can be a compressor 3 used for cooling in the battery temperature control system, wherein the compressor 3 is a refrigeration device in the refrigeration unit, used to output high-temperature and high-pressure refrigerant gas, and through the heat sink 24 and the condenser 4, the high-temperature and high-pressure refrigerant gas can be cooled and depressurized, and heat can be released. It should be noted that the heat released by the heat sink 24 can be used to heat the dehumidified gas flowing through the heat sink 24. Furthermore, the present application heats the dehumidified gas in the heat sink 24 through the compressor 3, and can make full use of the heat released by cooling and depressurizing the high-temperature and high-pressure refrigerant gas, and heat the dehumidified gas in the heat sink 24, so as to realize the reuse of the waste heat of the refrigeration unit in the battery temperature control system, so as to achieve the purpose of energy saving and emission reduction.
