[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0034] The following will refer to Figures 1 to 8 The present invention describes a column, an air circulation system, and a fuel cell vehicle according to embodiments of the present invention.
[0035] like Figures 1 to 8The air circulation system of the fuel cell vehicle according to the embodiment of the present application is shown. It comprises: a reactor 10, having an air inlet end 11 and an air outlet end 12; a first column 20, having a column air inlet channel, a first end of the column air inlet channel being communicated with the air inlet end 11 of the reactor 10, and a second end of the column air inlet channel being higher than the first end and communicated with external air; a second column 30, having a column air outlet channel, a first end of the column air outlet channel being communicated with the air outlet end 12 of the reactor 10, and a second end of the column air outlet channel being higher than the first end and communicated with external air; and an air blower 90, arranged between the first end of the column air outlet channel and the reactor 10, for making external air enter the reactor 10 through the column air inlet channel and making reacted gas be discharged to the outside through the column air outlet channel.
[0036] The air circulation system according to the embodiment of the present application makes external air enter the reactor 10 through the column air inlet channel of the first column 20 to react and cool the reaction at the same time, and makes reacted gas be discharged to the outside through the column air outlet channel of the second column 30. Compared with the prior art in which the positions of the air inlet and the air outlet are arranged at the bottom of the vehicle, the air circulation system according to the embodiment of the present application has the advantages that: 1. air is introduced into the reactor 10 through the first column 20 which is higher from the ground, so that the purity of the air entering the reactor can be improved, and the service life of the proton exchange membrane of the reactor can be effectively improved; 2. reacted gas is discharged through the second column 30 which is higher from the ground, and since the reacted gas is high in temperature and low in density, discharging from the top is more conducive to the discharge of the gas, so that the reacted gas can be effectively discharged and the safety hazard can be eliminated.
[0037] According to the embodiment of the present application, the inside of the first column 20 and the second column 30 can form a channel through which gas can pass. For example, the column air inlet channel and the column air outlet channel can be formed by surrounding the first column 20 and the second column 30 with outer housings. The first end (e.g. the lower end shown in Figure 1 ) of the column air inlet channel is connected with the air inlet end 11 of the reactor 10, and the second end of the column air inlet channel is higher than the first end and communicated with external air, so that relatively pure air at a higher position is provided to the reactor 10. The first end (e.g. the lower end shown in Figure 1 ) of the column air outlet channel is connected with the air outlet end 12 of the reactor 10, and the second end of the column air outlet channel is higher than the first end and communicated with external air, so that reacted gas at a higher temperature is easily discharged to the outside, and the safety hazard is eliminated.
[0038] Figure 1The first pillar 20 and the second pillar 30 shown in FIG. 1 are straight columns and are vertically arranged. However, the shape of the first pillar 20 and the second pillar 30 is not particularly limited, as long as the pillar air inlet passage through which air can enter can be formed inside the first pillar 20 and the pillar air outlet passage through which gas can be discharged can be formed inside the second pillar 30. For example, the first pillar 20 and the second pillar 30 can be arc-shaped. In addition, the arrangement of the first pillar 20 and the second pillar 30 is not limited to vertical arrangement, as long as the second end of the pillar air inlet passage is higher than the first end and the second end of the pillar air outlet passage is higher than the first end. For example, the first pillar 20 and the second pillar 30 can be arranged obliquely.
[0039] As an example, the first pillar 20 and the second pillar 30 can be formed as tubular members, and various structural reinforcements can be further arranged inside the first pillar 20 and the second pillar 30. The pillar air inlet passage and the pillar air outlet passage are not limited to be straight paths, and can be curved paths according to the shape of the first pillar 20 and the second pillar 30 and the shape of the structural reinforcements inside them.
[0040] According to an embodiment of the present application, the first pillar 20 can be an A-pillar, a B-pillar or a C-pillar of the fuel cell vehicle, and the second pillar 30 can be an A-pillar, a B-pillar or a C-pillar of the fuel cell vehicle. As an example, the first pillar 20 and the second pillar 30 can both be an A-pillar of the fuel cell vehicle. As another example, the first pillar 20 and the second pillar 30 can both be a B-pillar of the fuel cell vehicle. As another example, the first pillar 20 and the second pillar 30 can both be a C-pillar of the fuel cell vehicle. As another example, the first pillar 20 can be one of an A-pillar, a B-pillar and a C-pillar of the fuel cell vehicle, and the second pillar 30 can be another one of the A-pillar, the B-pillar and the C-pillar of the fuel cell vehicle.
[0041] According to an embodiment of the present application, the reactor 10 is a device for providing fuel reaction. Fuel gas (e.g. hydrogen, methanol, etc.) is stored in a gas cylinder and supplied to the reactor 10. External air enters the reactor 10 through the air inlet end 11 of the reactor 10 via the pillar air inlet passage, and the oxygen in the external air reacts with the fuel gas supplied to the reactor 10 in the reactor 10, and the chemical energy of the reaction is converted into electrical energy to power the vehicle. The reacted gas is discharged to the outside through the air outlet end 12 of the reactor 10 via the pillar air outlet passage.
[0042] According to an embodiment of this utility model, an exhaust fan 90 is disposed between the column exhaust channel and the reactor 10 for forced air circulation. That is, the exhaust fan 90 allows outside air to enter the reactor 10 through the column air intake channel and discharges the reacted gases to the outside through the column exhaust channel. The specific structure of the exhaust fan 90 is not limited, as long as it can achieve the aforementioned air circulation. As an example, the exhaust fan 90 can be an axial flow fan.
[0043] like Figure 1 As shown, the first pillar 20 may include a pillar air inlet 21 disposed at the top and communicating the pillar air intake passage with the outside air, and the second pillar 30 may include a pillar exhaust outlet 31 disposed at the top and communicating the pillar exhaust passage with the outside air. When the first pillar 20 and the second pillar 30 are the A-pillar, B-pillar, or C-pillar of a fuel cell vehicle, the pillar air inlet 21 and the pillar exhaust outlet 31 may be exposed to the outside from the roof of the fuel cell vehicle to provide the reactor 10 with the cleaner air at the roof and to easily discharge the high-temperature gas after the reaction to the outside.
[0044] According to an embodiment of the present invention, an air inlet 21 and an exhaust outlet 31 can be formed by opening the tops of the first column 20 and the second column 30. The specific shape and size of the air inlet 21 and the exhaust outlet 31 are not limited, as long as they can provide an inlet for air entry and an outlet for gas discharge.
[0045] Figure 2 yes Figure 1 A schematic diagram illustrating a variant example of the air circulation system in a fuel cell vehicle. (See diagram for example.) Figure 2 As shown, the first column 20 may further include a first filter 22 covering the column air inlet 21, and the second column 30 may further include a second filter 32 covering the column exhaust outlet 31. By providing the first filter 22 and the second filter 32, larger foreign objects can be prevented from entering the column air intake channel and the column exhaust channel through the column air inlet 21 and the column exhaust outlet 31.
[0046] Figure 3 yes Figure 1 A schematic diagram illustrating a variant example of the air circulation system in a fuel cell vehicle. (See diagram for example.) Figure 3As shown, the first stand column 20 can further include a first automatic reset flap 23 arranged at the bottom end of the first stand column 20 and covering the stand column air inlet passage. The first automatic reset flap 23 is arranged to be capable of automatically opening to discharge foreign matters and capable of automatically resetting after discharging foreign matters when the weight of foreign matters on the first automatic reset flap 23 is greater than a predetermined weight. The second stand column 30 can further include a second automatic reset flap 33 arranged at the bottom end of the second stand column 30 and covering the stand column air outlet passage. The second automatic reset flap 33 is arranged to be capable of automatically opening to discharge foreign matters and capable of automatically resetting after discharging foreign matters when the weight of foreign matters on the second automatic reset flap 33 is greater than a predetermined weight.
[0047] When the weight of foreign matters (e.g. rain or dust) on the first automatic reset flap 23 and the second automatic reset flap 33 is greater than a predetermined weight, the first automatic reset flap 23 and the second automatic reset flap 33 can automatically open downward to discharge the foreign matters, so as to keep the stand column air inlet passage and the stand column air outlet passage unblocked. After discharging the foreign matters, the first automatic reset flap 23 and the second automatic reset flap 33 can automatically close upward.
[0048] As an example, the first automatic reset flap 23 can be automatically opened and reset by a spring. For example, the spring can be arranged inside the first stand column 20, and two ends of the spring are connected to the inner side wall of the first stand column 20 and the first automatic reset flap 23 respectively. When the weight of foreign matters on the first automatic reset flap 23 exceeds a predetermined weight, the first automatic reset flap 23 opens downward to discharge the foreign matters, and after discharging the foreign matters, the first automatic reset flap 23 is automatically reset under the restoring force of the spring. The second automatic reset flap 33 can also be automatically opened and reset by the spring in the same way as the first automatic reset flap 23. According to the present application, by arranging the first automatic reset flap 23 and the second automatic reset flap 33, it can be avoided that water accumulates in the stand column air inlet passage and the stand column air outlet passage in rainy weather or that too much dust accumulates in the stand column air inlet passage and the stand column air outlet passage for a long time.
[0049] As shown in Figure 1 and Figure 2 According to the embodiment of the present application, the air circulation system can further include an air filter 51 arranged between the air inlet end 11 of the reactor 10 and the first end of the stand column air inlet passage. The air filter 51 can filter the external air, so as to provide pure air to the reactor 10.
[0050] As shown in Figure 1 and Figure 2 The air circulation system can further include a heating element 52 arranged between the air inlet end 11 of the reactor 10 and the air filter 51. According to the embodiment of the present application, the heating element 52 can be a PTC heating sheet, however, the present application is not limited thereto.
[0051] When the air temperature is low (e.g., in cold winter), the heating element 52 can be activated to heat the air, so that the air filtered by the air filter 51 is provided to the reactor 10 at a suitable temperature, which can effectively improve the life of the proton exchange membrane of the reactor. Alternatively, when the air temperature is high, the heating element 52 can not be activated.
[0052] As shown in Figs. 1 and 2, the air circulation system can further include an air inlet duct 50. The air filter 51 and the heating element 52 can be disposed in the air inlet duct 50. The air filter 51 can be disposed in an air filter slot of the air inlet duct 50. The air filter 51 is in interference fit with the air filter slot to ensure good sealing. In addition, the air filter 51 is replaceable. For example, when the air filter 51 is used for a period of time, it can be replaced to ensure the filtering effect.
