[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0019] like Figure 1 , Figure 2 and Figure 3As shown, a fuel cell humidifier reinforced internal component comprises two semi-inner tubes 1, which are connected as a whole by welding to form an internal component, and the upper and lower ends of the semi-inner tube 1 are respectively provided with a wet inlet 2 and a wet outlet 3 for installing a hollow fiber membrane, a moisture inlet 4 is provided on the outside of the wet inlet 2, a moisture outlet 5 is provided on the outside of the wet outlet 3, and ventilation windows 6 are evenly provided inside the moisture inlet 4 and the moisture outlet 5; a reinforcing rib 7 is fixedly installed on the outside of the semi-inner tube 1 near the wet inlet 2; a step 8 and a platform 9 are fixedly installed in the middle of the outside of the semi-inner tube 1, and a space for connecting with the humidifier is reserved between the step 8 and the platform 9.

[0020] The semi-inner tube 1 is a plastic component, and a welding seam 10 is formed at the connection of the semi-inner tube 1 .

[0021] In this embodiment, by matching the distance between the horizontal plate 11 of the humidifier and the step 8 and the insert 9, the welded half inner tube 1 of the inner component is inserted downward into the humidifier, and the humid air can enter the interior evenly through the ventilation window 6 of the moisture inlet 4, and the humid air is discharged evenly through the ventilation window 6 of the moisture outlet 5, so that the moisture and the hollow fiber membrane can fully exchange water. When the air flow is high, the reinforcing ribs 7 on the outside of the wet inlet end 2 are used to increase its strength to withstand the direct blowing of the wet incoming air, avoiding damage under the impact of high-speed wet air.

[0022] As an implementation method, Figure 2 As shown, the reinforcing ribs 7 are formed by a combination of transverse and longitudinal cross-sections, and the reinforcing ribs 7 surround the outside of the semi-inner tube 1.

[0023] In this embodiment, the reinforcing ribs 7 are arranged in three rows and four columns at the wet entry end 2 of the semi-inner tube 1 to increase its strength to resist the direct impact of the wet entry air and avoid damage under the impact of high-speed wet air.

[0024] As an implementation method, Figure 3 As shown, the inserting platform 9 is an inverted triangle structure, the step 8 is a rectangular structure, and the step 8 extends into the welding seam 10 .

[0025] In this embodiment, the step 8 and the insert 9 are used to fix the internal component in the humidifier. The distance between the step 8 and the insert 9 is consistent with the thickness of the horizontal plate 11 of the corresponding humidifier. The internal component is inserted downward into the humidifier, and the insert 9 can facilitate its insertion and prevent the internal component from being pulled out.

[0026] As an implementation method, Figure 2 As shown, the ventilation windows 6 are waist-shaped holes, and the ventilation windows 6 are at least ten groups.

[0027] In this embodiment, the vent window 6 of the moisture inlet 4 allows the moist air to enter the interior evenly, while the vent window 6 of the moisture outlet 5 allows the moist air to be discharged evenly, so that the moisture can fully exchange water with the hollow fiber membrane as a whole, thereby improving the moisture transfer efficiency.

[0028] As an implementation method, Figure 1 , Figure 2 As shown, the wet inlet end 2 and the wet outlet end 3 are both waist-shaped openings.

[0029] In this embodiment, air enters the interior of the channel through the ventilation window 6 of the moisture inlet 4, and the internal moisture fully exchanges water with the hollow fiber membrane.

[0030] Working principle: When in use, the distance between the horizontal plate 11 of the humidifier and the step 8 and the insert 9 is matched, and the welded half inner tube 1 of the inner component is inserted downward into the humidifier. The humid air can enter the interior evenly through the ventilation window 6 of the moisture inlet 4, and the humid air is discharged evenly through the ventilation window 6 of the moisture outlet 5, so that the moisture and the hollow fiber membrane can fully exchange moisture. When the air flow is high, the reinforcement ribs 7 outside the wet inlet end 2 are used to increase its strength to withstand the direct blowing of the wet air and avoid damage under the impact of high-speed wet air.
