Description

Technical Field

[0001] This utility model relates to the field of fuel cells, and in particular to a water separator for hydrogen fuel cells. Background Technology

[0002] A hydrogen fuel cell water separator is a device used to separate water and hydrogen. Its main function is to prevent water vapor from entering the fuel cell system, thereby protecting the normal operation of the fuel cell. In a fuel cell engine, the water separator is usually installed between the fuel cell stack and the ejector to achieve vapor-water separation and reduce the amount of liquid water entering the ejector. Existing water separators generally adopt the automatic drainage baffle type plus cyclone type, or cyclone type plus filter element type water separator.

[0003] However, in existing water distributors, the water distributor housing, hydrogen inlet connector, and hydrogen outlet connector are machined as a single piece, which can lead to some processing defects, such as steps inside the connector and non-rounded internal cavities, affecting water distribution efficiency. In addition, the material for the top cover produced by one-piece machining is very large, and a large part of the material is unusable, resulting in excessive processing time and increased costs. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a hydrogen fuel cell water separator. The bottom shell, top cover, hydrogen inlet connector, and hydrogen outlet connector are designed as separate units, which avoids some processing defects caused by the manufacturing process, saves materials and costs, and improves production efficiency.

[0005] The present invention provides a hydrogen fuel cell water separator, comprising a bottom shell, a top cover, baffles, and a connector assembly. The bottom shell has an inner cavity 1, within which a baffle portion 1 is integrally connected. The top cover has an inner cavity 2, within which baffle portions 2 and 3 are integrally connected. The top cover is detachably connected to the bottom shell, connecting cavity 1 and cavity 2. After connection, baffle portions 2 and 3 are located on opposite sides of baffle portion 1. A channel 1 is formed between the top of baffle portion 1 and the top of cavity 2 on the top cover; a channel 2 is formed between the bottom of baffle portion 2 and the bottom of cavity 1 on the bottom shell; and a channel 3 is formed between the bottom of baffle portion 3 and the bottom of cavity 1 on the bottom shell. The baffles are installed inside the bottom shell and the top cover, offset from baffle portions 1, 2, and 3. The connector assembly includes a hydrogen inlet connector and a hydrogen outlet connector detachably connected to the top cover, with the hydrogen inlet connector facing baffle portion 3 and the hydrogen outlet connector facing baffle portion 2.

[0006] Preferably, the top edge of the bottom shell has multiple connection holes one, and the bottom edge of the top cover has multiple connection holes two, and the bottom shell and the top cover are connected by bolts at the connection holes one and connection holes two.

[0007] Preferably, the bottom shell has multiple mounting holes.

[0008] Preferably, the bottom shell has a sealing groove along one edge of the cavity at its top, and a sealing ring is installed in the sealing groove, so that the bottom shell and the top cover are sealed together by the sealing ring.

[0009] Preferably, the top cover has a threaded hole one and a threaded hole two, the hydrogen inlet connector has an internal thread one that matches the threaded hole one, and the hydrogen outlet connector has an internal thread two that matches the threaded hole two.

[0010] Preferably, the bottom shell has a first insertion groove, the top cover has a second insertion groove corresponding to the first insertion groove, and the baffle is inserted into the first insertion groove and the second insertion groove.

[0011] Preferably, the baffle has multiple through holes arranged in an array.

[0018] Example 1, as Figures 1-4 As shown in the figure, a hydrogen fuel cell water separator proposed in this embodiment includes a bottom shell 1, a top cover 2, a baffle 5, and a connector assembly.

[0019] like Figure 3 As shown, the bottom shell 1 has a cavity on its inner side, and the cavity has an integrally connected baffle part 11, which can be perpendicular to the bottom of the cavity. The bottom shell 1 has multiple mounting holes 102, for example, four mounting holes 102, through which the water distributor can be installed and used.

[0020] The inner side of the upper cover 2 has a cavity 2, and the cavity 2 has an integrally connected baffle part 21 and baffle part 3 22, which can both be perpendicular to the top of the cavity 2.

[0021] The top cover 2 is detachably connected to the bottom shell 1, connecting the first cavity and the second cavity. Specifically, the top edge of the bottom shell 1 has multiple connecting holes 101, and the bottom edge of the top cover 2 has multiple connecting holes 201. The bottom shell 1 and the top cover 2 are connected by bolts at the connecting holes 101 and connecting holes 201. By screwing on nuts, the bottom shell 1 and the top cover 2 are securely connected.

[0022] The bottom shell 1 has a sealing groove 103 along one edge of the cavity at its top. A sealing ring is installed at the sealing groove 103. The bottom shell 1 and the top cover 2 are sealed together by the sealing ring to prevent leakage at the connection.

[0023] like Figure 1 and Figure 2 As shown, after the bottom shell 1 and the top cover 2 are connected, baffle part 21 and baffle part 3 22 are located on both sides of baffle part 11. A channel 1 is formed between the top end of baffle part 11 and the top end of cavity 2 of the top cover 2, a channel 2 is formed between the bottom end of baffle part 21 and the bottom end of cavity 1 of the bottom shell 1, and a channel 3 is formed between the bottom end of baffle part 3 22 and the bottom end of cavity 1 of the bottom shell 1. Channels 3, 1, and 2 are staggered.

[0024] like Figures 2-4 As shown, the baffle 5 is installed inside the bottom shell 1 and the top cover 2, and is staggered from the baffle part 11, baffle part 21, and baffle part 3 22. Multiple through holes are arranged in an array on the baffle 5. The bottom shell 1 has a first insertion slot, and the top cover 2 has a second insertion slot corresponding to the first insertion slot. The baffle 5 is inserted into the first insertion slot and the second insertion slot, and is individually inserted into the bottom shell 1 and the top cover 2.

[0025] The connector assembly includes a hydrogen inlet connector 3 and a hydrogen outlet connector 4 detachably connected to the upper cover 2. The hydrogen inlet connector 3 faces the baffle portion 22, and the hydrogen outlet connector 4 faces the baffle portion 21. The hydrogen inlet connector 3, channel 3, channel 1, channel 2, and hydrogen outlet connector 4 form a connected channel.

[0026] In this embodiment, the bottom shell 1, top cover 2, hydrogen inlet connector 3, and hydrogen outlet connector 4 are designed as separate units, avoiding some processing defects caused by manufacturing processes, saving materials and costs, and improving production efficiency. The bottom shell 1, top cover 2, hydrogen inlet connector 3, hydrogen outlet connector 4, and baffle 5 can be easily assembled. The baffle structure in the water separator effectively separates vapor and water. The hydrogen inlet connector 3 and hydrogen outlet connector 4 are reusable, saving costs.

[0027] Example 2, as Figures 1-4As shown, this embodiment proposes a hydrogen fuel cell water separator. Compared to Embodiment 1, in this embodiment, the upper cover 2 has a threaded hole 202 and a threaded hole 203. The hydrogen inlet connector 3 has an internal thread 1 that matches the threaded hole 202, allowing the hydrogen inlet connector 3 to be screwed into the threaded hole 202. The hydrogen outlet connector 4 has an internal thread 2 that matches the threaded hole 203, allowing the hydrogen outlet connector 4 to be screwed into the threaded hole 203. Both the hydrogen inlet connector 3 and the hydrogen outlet connector 4 are easy to assemble and disassemble.
