[0029] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

In the description of the embodiments of the present utility model, unless otherwise specified, the term "plurality" means two or more than two.

[0033] It has been found through research that the existing deionizer is provided with a filter element for filtering impurities. In order to ensure the deionization effect, the filter element needs to be replaced regularly and the impurities filtered out need to be cleaned.

[0034] There are two ways to replace the deionizer filter element in the prior art. One is to empty the coolant in advance, but the coolant needs to be released, and then refilled after the deionizer filter element is replaced. After refilling, a degassing operation is required, which is time-consuming and complicated to operate, and may contaminate the released coolant. The other method is to replace the coolant without emptying the coolant. Due to the internal pressure of the cooling system, the coolant overflows and splashes on the operator, which may cause harm to the operator's body and dirty the appearance of the fuel cell components. In addition, the overflowed coolant cannot be reused, resulting in waste.

[0035] In order to at least partially solve one or more of the above problems and other potential problems, the utility model provides a fuel cell deionizer and a fuel cell system to improve the efficiency and safety of deionizer filter element replacement through an integrated shut-off valve design.

[0036] In order to facilitate understanding of the fuel cell deionizer provided by the embodiment of the utility model, several specific embodiments will be used for explanation below.

[0037] Embodiment 1

[0038] like Figure 1 As shown in FIG. 2 , the utility model implements a fuel cell deionizer, comprising: a shell 1 and a cover 2; wherein:

[0039] The housing 1 has a storage space inside, and the top of the housing 1 has an opening, which is connected to the storage space;

[0040] The cover body 2 is arranged on the top of the housing 1, and the cover body 2 is used to block the opening;

[0041] The outer wall of the shell 1 is provided with at least one integrated port, which is communicated with the accommodating space, and the integrated port is connected to an integrated pipeline, which is located outside the shell 1; the integrated pipeline is provided with a stop valve, which is used to prevent liquid from flowing through the integrated pipeline.

[0042] The integrated port here is one or more, and usually may include two integrated ports (such as a first integrated port 111 and a second integrated port 112). Figure 1 As shown, the first integrated port 111 serves as an integrated inlet, and the second integrated port 112 serves as an integrated outlet. The reason why the embodiment of the utility model adopts the form of an integrated port is mainly to simplify the complexity of the cooling system pipeline, and to achieve a higher degree of integration. At the same time, the shut-off valve provided on the integrated pipeline connected by the integrated port can prevent the liquid from flowing through the integrated pipeline, that is, when it is determined that the deionizer filter element needs to be replaced, there is no need to drain the coolant in the deionizer, and only the shut-off valve needs to be closed. When the shut-off valve is closed, the coolant in the deionizer will not continue to overflow, thereby avoiding the potential safety hazard caused by the continuous overflow of the coolant in the prior art.

[0043] The integrated port here is communicated with the accommodating space inside the shell 1, and the integrated port is connected to an integrated pipeline, through which the liquid can flow in or out. For example, when the integrated port is used as an integrated inlet, the liquid can flow in easily. For another example, when the integrated port is used as an integrated outlet, the liquid can flow out easily, and so on.

[0044] like Figure 1 As shown, the first integrated port 111 and the second integrated port 112 are connected to two integrated pipelines, which are respectively recorded as the integrated inlet pipeline 121 and the integrated outlet pipeline 122. An inlet stop valve 131 is correspondingly arranged on the integrated inlet pipeline 121 to prevent liquid from overflowing from the first integrated port 111 when the coolant is not emptied for filter element replacement; similarly, an outlet stop valve 132 is correspondingly arranged on the integrated outlet pipeline 122 to prevent liquid from overflowing from the second integrated port 112 when the coolant is not emptied for filter element replacement.

[0045] Both the inlet stop valve 131 and the outlet stop valve 132 may be electric valves, manual valves, or other valves with liquid blocking function, and no specific restrictions are made here.

[0046] In addition, the shell 1 in the embodiment of the utility model adopts an open design, and the accommodating space inside the shell 1 is connected to the opening, which can facilitate the replacement of the filter element. When there is no need to replace the filter element, the opening can be blocked by the cover body 2, and the entire structural design is more reasonable.

[0047] Embodiment 2

[0048] The integrated pipeline in the embodiment of the utility model comprises a first end and a second end, and the first end of the integrated pipeline is connected to the housing 1; wherein:

[0049] The integrated pipeline is provided with an installation port, and the installation port is located between the first end and the second end of the integrated pipeline;

[0050] The stop valve is arranged on the integrated pipeline through the installation port.

[0051] by Figure 1 Taking the integrated inlet pipeline 121 as an example, the first end of the integrated inlet pipeline 121 is connected to the housing 1, and the inlet stop valve 131 can be set on the integrated inlet pipeline 121 through the first installation port 121a set by the integrated inlet pipeline 121 to meet the liquid overflow prevention requirement of the first integrated port 111; Figure 1 Taking the integrated outlet pipeline 122 as an example, the first end of the integrated outlet pipeline 122 is connected to the shell 1, and the outlet stop valve 132 can be set on the integrated outlet pipeline 122 through the second installation port 122a set by the integrated outlet pipeline 122 to meet the liquid overflow prevention requirements of the second integrated port 112.

[0052] Embodiment 3

[0053] based on Figure 1 It can be known that the embodiment of the utility model defines two integrated ports with a height difference, namely, a first integrated port 111 as an integrated inlet and a second integrated port 112 as an integrated outlet; in the height direction of the shell 1, the second integrated port 112 is located above the first integrated port 111. The height difference design can ensure a more reasonable structural design while better avoiding the potential safety hazards caused by the overflow of coolant when the filter element is replaced.

[0054] In addition, the integrated pipeline connected to the first integrated port 111 is coaxially arranged with the shell 1, and the axial direction of the integrated pipeline connected to the second integrated port 112 is perpendicular to the axial direction of the shell 1, thereby further avoiding the potential safety hazard caused by the overflow of coolant when the filter element is replaced.

[0055] like Figure 1 As shown, among the two integrated openings in the embodiment of the utility model, the first integrated opening 111 is located at the bottom of the shell 1 , and the second integrated opening 112 is located at the side wall of the shell 1 .

[0056] In addition, the integrated inlet pipeline 121 connected to the first integrated port 111 is coaxially arranged with the shell 1 , and the axial direction of the integrated outlet pipeline 122 connected to the second integrated port 112 is perpendicular to the axial direction of the shell 1 .

[0057] Embodiment 4

[0058] The accommodating space in the embodiment of the utility model is provided with a filter element 14 , and the radial dimension of the filter element 14 is smaller than the radial dimension of the housing 1 .

[0059] Here, in the direction from the bottom to the top of the shell 1, the radial size of the filter element 14 gradually increases, that is, the embodiment of the utility model adopts a filter element structure that is wide at the top and narrow at the bottom, which will well ensure the filtering effect of the filter element 14 and improve the service life of the deionizer.

[0060] At the same time, in order to ensure a more fitting structural design, in the embodiment of the utility model, the radial dimension of the shell 1 gradually increases from the bottom to the top of the shell 1.

[0061] Embodiment 5

[0062] In order to further improve the integration, the integrated pipeline and the shell 1 are designed to be integrally formed.

[0063] like Figure 2 As shown, the integrated inlet pipeline 121 is integrally formed with the shell 1, and the integrated outlet pipeline 122 is also integrally formed with the shell 1, which will further simplify the complexity of the cooling system pipelines.

[0064] In combination with the fuel cell deionizers provided in the above-mentioned embodiments 1 to 5, the embodiments of the utility model also provide a fuel cell system, which adopts a fuel cell deionizer with a more compact structure and higher integration, simplifies the complexity of system design, and has greater practical value.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, unless they are contradictory.
