Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and fig. 2, the present invention provides a deionization tank, including: a housing 103 having an inlet 101 and an outlet 105, an ion adsorption part 104 provided in the housing 103 and capable of adsorbing ions, a color changing part 106 provided at the outlet 105; the color changing portion 106 changes color after passing through the ion flow, and the housing 103 has a transparent portion through which the color changing portion 106 can be observed.
The working principle of the deionization tank is as follows: the cooling liquid enters the housing 103 from the inlet 101, then flows through the ion adsorption part 104, the ion adsorption part 104 adsorbs ions in the cooling liquid, the cooling liquid flowing through the ion adsorption part 104 flows through the color changing part 106, if ions are still contained in the cooling liquid flowing through the ion adsorption part 104, the color changing part 106 changes color, if ions are not contained in the cooling liquid flowing through the ion adsorption part 104, the color changing part 106 does not change color, and finally the cooling liquid flowing through the color changing part 106 flows out of the housing from the outlet 105.
It should be noted that, during long-time operation of the fuel cell vehicle, ions are precipitated in the coolant and are precipitated little by little as accumulated over time, and according to the ion precipitation experiment of the entire vehicle, the change of the conductivity of the entire cooling system per day is 0.5uS/cm, and when the fuel cell is operated, the coolant passes through the ion tank continuously, the coolant is adsorbed by the ion adsorption portion 104, and the ions generated in the coolant cannot reach the color change portion 106; when the ions are not adsorbed by the adsorbing portion 104, the ions reach the color changing portion 106, so that the color changing portion 106 changes color.
The ion adsorption unit 104 does not adsorb any more until it is saturated; the deionization tank is generally placed on a branch path in the whole cooling circulation pipeline, and the flow and the pressure are very small, so that the ion adsorption part 104 has enough time to completely adsorb when the cooling liquid passes through the deionization tank; the evolution of ions in the cooling liquid does not increase instantaneously but rather over a long period of operation and build-up formation and the conductivity rises a little bit per day. According to the same adsorption mode, ions generated in the cooling liquid are adsorbed by the deionization tank, after long-term adsorption, the ion adsorption part 104 in the deionization tank is saturated in adsorption, the ions in the cooling liquid can pass through the color changing part 106, the color of the color changing part 106 changes, after a period of time, the color of the color changing part 106 changes obviously, and the change can be observed by naked eyes.
It can be understood that if the coolant after passing through the ion adsorption part 104 still contains ions, the higher the concentration of the ions, the greater the degree of color change of the color changing part 106; the smaller the ion concentration is, the smaller the degree of color change of the color changing portion 106 is. Thus, the condition of the ion adsorbing portion 104 can be known from the degree of color change of the color changing portion 106, and the condition of the entire deionization tank can be known.
The embodiment of the utility model provides a deionizer sets up the portion of discolouing 106 through export 105 department at casing 103, and this portion of discolouing 106 is discolourd after being flowed through by the ion, and casing 103 has the transparent portion that can observe the portion of discolouing 106, if the staff observes the portion of discolouing 106 from transparent portion, then indicates that there is the ion to flow through the portion of discolouing 106, has indicated ion adsorption portion 104 promptly and has adsorbed the saturation, need change the deionization jar this moment. Therefore, the utility model provides a deionization jar can show directly perceivedly whether deionization jar is changed, can learn promptly that deionization jar needs to be changed.
In the deionization tank, in order to prevent the ion adsorption part 104 from entering the outlet 105 and the inlet 101, the deionization tank further comprises a baffle plate 102 which is arranged in the housing 103 and can block the ion adsorption part 104 from entering the inlet 101 and the outlet 105; wherein the color changing portion 106 is located between the outlet 105 and the baffle 102 adjacent thereto. It is understood that the baffle 102 has through holes for the passage of the cooling liquid.
Specifically, at least two baffles 102 are disposed at both ends of the ion adsorbing portion 104. In order to simplify the structure, it is preferable to select two baffles 102, which are provided at both ends of the ion adsorbing portion 104.
The material of the baffle plate 102 is selected according to actual needs, for example, the baffle plate 102 is a polypropylene resin plate, which is not limited in this embodiment.
The size and shape of the baffle plate 102 also need to be selected according to actual needs, which is not limited in this embodiment.
Preferably, the baffle 102 is hermetically connected to the housing 103. For the specific sealing structure, it is selected according to actual needs, for example, the sealing structure is connected by a sealing ring in a sealing manner, which is not limited in this embodiment.
The color-changing part can be color-changing resin or color-changing test paper, and is selected according to actual needs. In order to improve the service life, the color changing portion 106 includes a color changing resin.
The ion adsorbing portion 104 may be any type as long as it can adsorb ions, and the specific type of the ion adsorbing portion 104 is selected according to actual needs, and for example, the ion adsorbing portion 104 includes anion and cation resin beads. Preferably, the ion adsorption unit 104 is of a gel type, and the volume of the ion adsorption unit 104 increases after adsorbing ions.
In the deionization tank, the inlet 101 is positioned at the top end of the shell 103, and the outlet 105 is positioned at the bottom end of the shell 103, as shown in FIG. 1; alternatively, the inlet 101 is located at the bottom end of the housing 103 and the outlet 105 is located at the top end of the housing 103, as shown in FIG. 2.

Based on the deionization jar that above-mentioned embodiment provided, the embodiment of the utility model provides a fuel cell cooling system is still provided, as shown in fig. 3, this fuel cell cooling system includes deionization jar 1, and this deionization jar 1 is the deionization jar that above-mentioned embodiment said.
Since the deionization tank provided by the above embodiment has the above technical effects, and the fuel cell cooling system includes the above deionization tank, the fuel cell cooling system also has corresponding technical effects, and details are not repeated herein.
The volume of the ion adsorption part 104 of the deionization tank 1 becomes large after adsorbing ions, and the more ions are adsorbed by the ion adsorption part 104, the greater the resistance of the coolant passing through the ion adsorption part 104, and therefore, it is possible to determine whether the deionization tank 1 needs to be replaced by the pressure difference between the inlet and the outlet of the deionization tank 1.
Specifically, a first pressure sensor 4 and a second pressure sensor 5 are connected in series to a pipeline where the deionization tank 1 is located, the first pressure sensor 4 is located at an inlet end of the deionization tank 1, and the second pressure sensor 5 is located at an outlet end of the deionization tank 1.
The distance between the first pressure sensor 4 and the inlet of the deionization tank 1 and the distance between the second pressure sensor 5 and the outlet of the deionization tank 1 need to be within a set range, so that errors are avoided, and the judgment result is influenced. For example, the distance between the first pressure sensor 4 and the inlet of the deionization tank 1 and the distance between the second pressure sensor 5 and the outlet of the deionization tank 1 are both 50 cm.
In the practical application process, if the detection difference value between the second pressure sensor 5 and the first pressure sensor 4 is not greater than the set pressure difference value, it indicates that the deionization tank 1 does not need to be replaced, and if the detection difference value between the second pressure sensor 5 and the first pressure sensor 4 is greater than the set pressure difference value, it indicates that the deionization tank 1 needs to be replaced.
In order to improve the reliability, it is preferable that the deionization tank 1 needs to be replaced when the difference between the detection values of the second pressure sensor 5 and the first pressure sensor 4 is larger than the set pressure difference value and the color changing section 106 changes color.
In order to timely know that the detection difference value of the first pressure sensor 4 and the second pressure sensor 5 is greater than the set pressure difference value, the fuel cell cooling system further comprises an alarm which can alarm when the detection difference value of the first pressure sensor 4 and the second pressure sensor 5 is greater than the set pressure difference value, and the first pressure sensor 4 and the second pressure sensor 5 are both connected with the alarm.
It will be appreciated that the first pressure sensor 4 and the second pressure sensor 5 are both electrically connected to the alarm.
The type of the alarm is selected according to actual needs, for example, the alarm is an alarm lamp or a buzzer, and this embodiment does not limit this.
In order to avoid the influence of ions on the electric pile 6, the deionization tank 1 is preferably arranged on a cooling liquid inlet pipe of the electric pile 6 in a bypass mode. Therefore, the condition of the cooling liquid entering the galvanic pile 6 can be known in time, and the cooling liquid entering the galvanic pile 6 is prevented from carrying ions.
Of course, the deionization tank 1 may be disposed at other positions, and is not limited to the above embodiment.
In order to further optimize the above technical solution, the fuel cell cooling system further comprises a conductivity meter 8 connected in series to the pipeline of the fuel cell cooling system. The conductivity meter 8 detects the conductivity of the coolant, and thus, whether or not to replace the deionization tank 1 can be also determined based on the conductivity of the coolant.
Specifically, when the detected value of the conductivity meter 8 is greater than the set value, the deionization tank 1 needs to be replaced. In practical application, the deionization tank 1 can be selected to be replaced when the detection value of the conductivity meter 8 is greater than the set value and the color change part 106 changes color. Further, when the detection value of the conductivity meter 8 is larger than the set value, the detection difference value of the second pressure sensor 5 and the first pressure sensor 4 is larger than the set pressure difference value, and the color changing portion 106 changes color, the deionization tank 1 needs to be replaced. For example, when the detection value of the conductivity meter 8 is greater than 10uS/cm and the detection difference between the second pressure sensor 5 and the first pressure sensor 4 is greater than 40kPa, the color change portion 106 of the deionization tank 1 is visually observed to change color, and it can be determined that the lifetime of the deionization tank 1 has come and needs to be replaced.
Above-mentioned fuel cell cooling system can go to change deionization jar 1 not being restricted to the cycle that the producer recommends, has reduced the change number of times, has prolonged the change cycle, can reduce the maintenance cost in later stage to a certain extent.
The specific position of the deionization tank 1 is selected according to actual needs, for example, the deionization tank 1 is located at the coolant outlet end of the stack 6, which is not limited in this embodiment.
When the self-deionization tank 1 is invalid, the fuel cell vehicle can not run to the maintenance position, in order to avoid the situation, the fuel cell cooling system further comprises an auxiliary deionization tank 2 which is connected with the deionization tank 1 in parallel, and a branch at which the auxiliary deionization tank 2 is arranged is connected with a valve 3 in series.
In the structure, the valve 3 can be opened according to the requirement, so that the cooling liquid flows through the auxiliary deionization tank 2 to meet the requirement. For example, when the conductivity of the cooling liquid is very high, the deionization tank 1 cannot reduce ions and report the insulation fault of the whole vehicle, and the fuel cell vehicle can open the valve 3 manually or electrically on the running line, so that part of the cooling liquid flows through the auxiliary deionization tank 2, the ion concentration of the whole system is reduced, the vehicle can be driven to the maintenance position normally, and unnecessary cost can be reduced when the fuel cell vehicle breaks down.
The valve 3 may be a manual valve or an electric valve, and is selected according to actual needs, which is not limited in this embodiment.
For the specific structure of the auxiliary deionization tank 2, the design can be made with reference to the structure of the deionization tank 1, and the existing deionization tank can also be referred to. Since the auxiliary deionization tank 2 is in a standby state, the volume of the auxiliary deionization tank 2 is selected to be smaller than that of the deionization tank 1 in order to reduce costs.
