AI Technical Summary
During the production of fuel cell membrane tube humidifiers, due to the drying and bending of the membrane tubes, the straightness after assembly is insufficient, and some membrane tubes will warp and bend. This makes the membrane tubes in the support frame prone to warping and bending, and thus prone to breakage after the resin glue cures.
A contouring fixture for the end face of the membrane tube bundle of a fuel cell humidifier is adopted, including a first clamping plate and a second clamping plate. The clamping plate is provided with a receiving groove to form a strip hole. After the clamping plates are joined together, an R-angle is formed to press the end face of the membrane tube bundle, ensuring that the membrane tubes are evenly and tightly distributed, providing support, and preventing warping and breakage.
It achieves uniform and dense distribution of membrane tubes, improves the membrane tubes' resistance to gas impact, extends the service life of membrane tube humidifiers, and standardizes the membrane tube dispersion and shape control after glue filling during the production process.

[0035] As shown in Figures 1 to 4 The utility model discloses a fuel cell humidifier membrane tube bundle end face profiling tool which comprises a first clamping plate 1, a first accommodating groove 11 is arranged on the first clamping plate 1, a second clamping plate 2, a second accommodating groove 21 is arranged on the second clamping plate 2, the first clamping plate 1 and the second clamping plate 2 are butted to form a strip-shaped hole with the first accommodating groove 11 and the second accommodating groove 21, and R angles 3 are arranged at each corner (the total number of corners can be four) of the strip-shaped hole, that is, in the first accommodating groove 11, R angles 3 are arranged between the two side walls of the first accommodating groove 11 and the groove bottom respectively, and in the second accommodating groove 21, R angles 3 are arranged between the two side walls of the second accommodating groove 21 and the groove bottom respectively.
[0036] In the embodiment, after a plurality of membrane tubes are assembled to the support frame, the plurality of membrane tubes form a membrane tube bundle, and the two ends of the membrane tube bundle extend out of the two ends of the support frame. In the thickness direction of the membrane tube bundle, the first clamping plate 1 is pressed on one side of the membrane tube bundle, the second clamping plate 2 is pressed on the other side of the membrane tube bundle, the first clamping plate 1 and the second clamping plate 2 are connected and fixed (the length direction of the strip-shaped hole is consistent with the width direction of the membrane tube bundle, and the width direction of the strip-shaped hole is consistent with the thickness direction of the membrane tube bundle), the membrane tube bundle fills the strip-shaped hole, the shape of the strip-shaped hole can limit the shape of the end face of the membrane tube bundle, and even the shape of the strip-shaped hole is the shape of the end face of the membrane tube bundle, the first clamping plate 1 and the second clamping plate 2 can press the end part of the membrane tube bundle, the plurality of membrane tubes can be closely arranged, the gap between the membrane tubes is smaller, a supporting force can be formed when the membrane tubes are impacted by gas, the membrane tubes that are warped and bent and the surrounding membrane tubes are closely arranged, the structure gap around the membrane tubes after resin fixation is uniform, and therefore the membrane tubes that are warped and bent can be prevented from being broken.
[0037] Therefore, the fuel cell humidifier membrane tube bundle end face profiling tool provided by the embodiment can uniformly and closely arrange the end parts of the plurality of membrane tubes, can form a supporting force, can prevent the membrane tubes from shaking when the membrane tubes are impacted by gas flow, and can improve the service life of the fuel cell membrane tube humidifier. In addition, when the fuel cell humidifier membrane tube bundle end face profiling tool is installed at the two ends of the membrane tube bundle, the dispersion uniformity of the membrane tubes at the two ends of the internal support frame in the production process of the fuel cell membrane tube humidifier can be unified, the cross-sectional shape after glue pouring can be controlled, and a standardized monitoring mode can be formulated.

[0039] When the support frame of the fuel cell humidifier is subjected to the impact of gas flow, the impact on the circular arc of the support frame (that is, on both sides in the width direction of the support frame) is greater. However, in the fuel cell humidifier membrane tube bundle end face profiling tool of the present embodiment, at least one of the groove bottom of the first accommodating groove 11 and the groove bottom of the second accommodating groove 21 is arranged in an inwardly convex arc shape, so that the middle part of the strip-shaped hole is narrow and the two ends are wide, and the membrane tube can be fully filled to both sides of the support frame (both sides in the width direction of the support frame, that is, the R angle of the support frame); after glue filling, the membrane tube filling on both sides of the support frame is relatively tight, the impact resistance of the membrane tube when subjected to the impact of gas flow is improved, thereby improving the service life of the humidifier and reducing the vehicle rescue caused by the problem of humidification efficiency, greatly saving the cost of after-sales bad quality.
