[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains.

[0021] like Figures 1 to 2 As shown, a fuel cell humidifier device includes a cylindrical body 3 with an open upper surface. An end cap 4 is fitted to the upper end of the cylindrical body 3. A baffle 1 is vertically arranged on one side inside the cylindrical body 3. A baffle strip 5 is arranged above the baffle 1 and connected to the top wall of the end cap 4. There is a gap between the baffle 1 and the baffle strip 5. A dry outlet 2 communicating with the cylindrical body 3 is arranged on one side of the cylindrical body 3. The baffle 1 is arranged close to the dry outlet 2. A flow channel 6 is formed between the side wall of the cylindrical body 3 on the side with the dry outlet 2 and the baffle 1. A dry inlet communicating with the cylindrical body 3 is arranged on the cylindrical body 3.

[0022] Several inlets are located on the other side of the cylinder 3. The baffle 1 is located between the dry inlet and the dry outlet 2. After dry air enters the cylinder 3 through the dry inlet, it enters the flow channel 6 through the gap between the baffle 1 and the baffle bar 5, and then exits from the dry outlet 2. This device integrates the internal flow channel 6 through the baffle 1, which facilitates layout. By arranging the cylinder 3, the dry outlet 2 can be arbitrarily adjusted in the front and rear positions of the cylinder 3, which is convenient for users to arrange, improves space utilization, has a simple structure, is easy to install, enhances layout diversity, improves the space utilization of the fuel cell system, and has wide applicability and higher internal exchange rate.

[0023] If the dry inlet is located on the side of the cylinder 3 where the dry outlet 2 is located, and the dry inlet and dry outlet 2 are on the same side of the baffle 1, dry air enters the cylinder 3 through the dry inlet and is discharged from the dry outlet 2 through the flow channel 6. This eliminates the need for an external pipe to connect the dry inlet and dry outlet 2, making it convenient for the user. In addition, when the dry air flows in the flow channel 6, it is easy to pass through the gap between the baffle 1 and the baffle bar 5 for heat exchange, reducing the volume of the humidifier device.

[0024] Among them, the baffle 5 is welded to the end cover 4, and the welding position is directly opposite to the position of the baffle 1 on the cylinder 3, so as to achieve a sealing effect.

[0025] At least one wet outlet is provided on one side of the dry inlet, and at least one wet inlet is provided on one side of the dry outlet 2. The number of wet outlets is the same as the number of wet inlets, and the wet outlets are configured in conjunction with the wet inlets corresponding to the wet outlets.

[0026] The wet outlet and wet inlet are symmetrically arranged about the cylinder 3, with respect to each other.

[0027] The upper end of the baffle 1 is provided with an upper guide plate. The upper end thickness of the upper guide plate is less than the lower end thickness of the upper guide plate, which facilitates the guidance of dry air.

[0028] The lower end of the baffle 5 is provided with a lower guide plate. The upper end of the lower guide plate is thicker than the lower end of the lower guide plate, which facilitates the guidance of dry air.

[0029] To prevent impurities and dust from accumulating inside the humidifier and affecting its performance, both the dry inlet and the wet inlet are equipped with filters.

[0030] To facilitate the fastening between the cylinder 3 and the end cap 4, the upper end face of the cylinder 3 is provided with a plurality of lower threaded holes at equal intervals, and the end cap 4 is provided with a plurality of upper threaded holes that cooperate with the lower threaded holes. The cylinder 3 and the end cap 4 are fastened together by bolts passing through the lower threaded holes and the upper threaded holes.

[0031] An annular washer is provided on the lower end face of the end cap 4. The lower end of the annular washer is in contact with the upper end face of the cylinder 3, which improves the sealing performance after the cylinder 3 and the end cap 4 are connected.

[0032] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0033] The embodiments of this utility model are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
