Description

Technical Field

[0001] This application relates to the field of new energy vehicle technology, and more specifically, to a quick-replaceable ion exchanger for fuel cell vehicles. Background Technology

[0002] To meet the power requirements of the vehicle, fuel cell systems often operate in a high-current, high-voltage environment, placing high demands on electrical safety. In fuel cell systems, the coolant is in direct contact with the metal bipolar plates, which have excellent conductivity. To prevent current from being transferred to the outside through the coolant and causing a safety accident, the coolant conductivity must be kept at a low value to ensure good insulation of the fuel cell system.

[0003] Typically, to ensure the coolant's conductivity remains within acceptable limits, an ion exchanger is installed in the cooling circuit. This exchanger uses neutral groups in the ion exchange resin to exchange cations and anions in the coolant, reducing its conductivity. However, the total ion adsorption capacity of the ion exchanger is limited, requiring replacement after a period of use. Replacement often necessitates dismantling some cooling pipes and draining some coolant, which is wasteful given the high cost of fuel cell-specific coolants. Furthermore, existing ion exchangers, due to their installation structure, often require significant time and effort to replace. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a quick-replaceable ion exchanger for fuel cell vehicles, aiming to improve upon the problem in existing quick-replaceable ion exchangers for fuel cell vehicles where the fixed position of the mold block on the base is limited.

[0005] This application proposes a quick-replaceable ion exchanger for fuel cell vehicles, comprising a resin tank, wherein an inlet connection end plate and an outlet connection end plate are respectively sealed and connected to both ends of the resin tank. A ball valve is respectively provided on the inlet connection end plate and the outlet connection end plate. Quick-release latches are respectively fitted between the inlet connection end plate and the resin tank and the resin tank. The quick-release latch includes a retaining ring and a locking nut threadedly connected to the retaining ring. The retaining ring is sealed and fitted at the connection between the inlet connection end plate and the resin tank and the connection between the outlet connection end plate and the resin tank.

[0006] According to an embodiment of this application, a quick-replaceable ion exchanger for fuel cell vehicles has the following advantages:

[0007] 1. The quick-release structure greatly reduces replacement time and improves the convenience of replacement;

[0008] 2. The design incorporates a ball valve and a liquid storage tank, enabling zero waste of coolant when replacing the ion exchanger and reducing after-sales costs;

[0009] 3. An impurity collection tank is installed to filter out impurities in the cooling circuit, preventing blockage of the ion exchanger and affecting other parts in the water circuit, thus improving the system's fault tolerance;

[0010] 4. The impurity collection tank can be disassembled separately, cleaned, and reused multiple times, reducing operating costs;

[0011] 5. When replacing the ion exchanger, only the filter element needs to be replaced, instead of the entire ion exchanger assembly, which reduces maintenance costs.

[0012] In addition, a quick-replaceable ion exchanger for fuel cell vehicles according to an embodiment of this application also has the following additional technical features:

[0013] In some specific embodiments of this application, the inlet connection end plate and the outlet connection end plate have the same structural size.

[0014] In some specific embodiments of this application, a sealing gasket is coaxially disposed between the inlet connection end plate and the resin tank.

[0015] In some specific embodiments of this application, a liquid storage tank is coaxially provided on the inner side of the inlet connection end plate.

[0016] In some specific embodiments of this application, a plurality of fixing blocks are uniformly arranged on the circumferential side of the liquid storage tank.

[0017] In some specific embodiments of this application, impurity collection tanks are coaxially embedded at both ends of the resin tank, and multiple through holes are uniformly provided on the side wall and bottom of the impurity collection tank.

[0018] In some specific embodiments of this application, the open end of the impurity collection tank is provided with a plurality of snap-fit ​​fins evenly distributed around its circumference.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] like Figures 1-6 As shown, a quick-replaceable ion exchanger for a fuel cell vehicle according to an embodiment of this application includes a resin tank 1, wherein, as... Figures 1-3 As shown, the resin tank 1 is sealed and connected to an inlet connection plate 11 and an outlet connection plate 12 at both ends. Ball valves 13 are respectively installed on the inlet connection plate 11 and the outlet connection plate 12. It can be understood that when the cooling system is running, both ball valves 13 at both ends are in the open state, and the coolant flows normally. When the ion exchanger needs to be replaced, the two ball valves 13 are closed by rotating the switch handle, which will cut off the flow of coolant.

[0030] The inlet connecting end plate 11 and the outlet connecting end plate 12 are respectively fitted with quick-release locking buckles 2 between them and the resin tank 1. The quick-release locking buckle 2 includes a retaining ring 21 and a locking nut 22 threadedly connected to the retaining ring 21. The retaining ring 21 is sealed at the connection between the inlet connecting end plate 11 and the resin tank 1, and between the outlet connecting end plate 12 and the resin tank 1. It can be understood that the retaining ring 21 can squeeze and fasten the inlet connecting end plate 11 and the outlet connecting end plate 12 to the resin tank 1 through the locking nut 22. Conversely, when disassembling, the retaining ring 21 can be made to contact the fastened connection state by rotating the locking nut 22 in the opposite direction, so as to realize the quick replacement of the ion exchanger filter element, reduce the replacement time, and the separable design of the resin tank 1 and the two connecting end plates means that only the resin tank 1 needs to be replaced when replacing, without replacing the entire ion exchanger, which can reduce the operating cost.

[0031] It should be noted that, in the embodiments of this application, the parts where the inlet connecting end plate 11 and the outlet connecting end plate 12 connect to the resin tank 1 are designed with a sealing ring groove structure, such as... Figure 4 and Figure 5 As shown, the inlet connection end plate 11 and the outlet connection end plate 12 are identical in size, and a sealing gasket 14 is coaxially arranged between them and the resin tank 1. By pressing the two connection end plates and the resin tank 1 with two quick-release latches 2, the sealing gasket 14 is deformed and filled into the sealing groove between the two connection end plates and the resin tank 1, thereby achieving a sealing effect and ensuring that the coolant does not leak during the use of the ion exchanger.

[0032] like Figures 3-5 As shown, impurity collection tanks 3 are coaxially embedded at both ends of resin tank 1. Multiple through holes are evenly provided on the side wall and bottom of impurity collection tank 3 to allow coolant to flow and to filter and collect impurities in the coolant, preventing large particles of impurities from clogging resin tank 1 and hindering normal liquid flow.

[0033] It should be noted that, as Figure 6 As shown, a liquid storage tank 15 is coaxially arranged on the inner side of the inlet connection end plate 11. Multiple fixing blocks 16 are evenly arranged on the circumferential side of the liquid storage tank 15. The design of the liquid storage tank 15 allows the residual coolant inside the tank to be collected when the ion exchanger is replaced, reducing the waste of coolant.

[0034] like Figure 6As shown, multiple snap-fit ​​fins 31 are evenly arranged circumferentially on the open end of the impurity collection tank 3. The snap-fit ​​fins 31 are rotatably connected to the liquid storage tank 15 and engage with the fixing block 16. The liquid storage tank 15 and the snap-fit ​​fins 31 are installed between the impurity collection tank 3 and the two connecting end plates. During normal operation, the impurity collection tank 3 is connected to the two connecting end plates through the above structure. When replacing or maintaining the ion exchanger, the two impurity collection tanks 3 can be taken out together with the two connecting end plates. The impurity collection tank 3 can be removed from the connecting end plates by rotating it at a specific angle, thus cleaning the impurity collection tank 3 and facilitating reuse. The impurity collection tank 3 and the connecting end plates are designed with a snap-fit ​​connection. Through the limiting of the fixing block 16 and the snap-fit ​​fins 31, the impurity collection tank 3 can be quickly cleaned, maintained and replaced.

[0035] It should be noted that the specific models and specifications of resin tank 1, ball valve 13 and locking nut 22 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
