Description

Technical Field

[0001] The present application relates to the technical field of battery humidifiers, and in particular to a humidifier box for a hydrogen fuel cell. Background Art

[0002] The main function of a fuel cell humidifier is to provide appropriate moisture to the fuel cell to ensure its normal and efficient operation. Specifically, the humidifier generates water vapor by heating water to boiling, and then evenly distributes it in the air conditioning box or air duct through a steam spray rod, and absorbs it through the air to achieve the purpose of humidification. In a fuel cell, the proton exchange membrane needs to work under certain humidity conditions to ensure good working efficiency, which requires a humidifier. The function of the humidifier is to provide sufficient moisture to the fuel cell by circulating the water evaporating at the cathode.

[0003] The two ends of a traditional humidifier are fixed by screwing multiple bolts. Although it has high stability, the assembly workload after the humidifier is produced is large. The staff needs to screw multiple bolts, which will increase the assembly time of the humidifier and reduce the output efficiency of the finished product. It is also inconvenient to disassemble and recycle the waste humidifier. Utility Model Content

[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0020] The present application embodiment discloses a humidifier housing for a hydrogen fuel cell. Figure 1-Figure 3 , a humidifier box for a hydrogen fuel cell, comprising a humidifier shell 1 and a sealing cover 3. The outer wall of the humidifier shell 1 is provided with a heat conductive sheet integrally formed therewith, which can improve the heat dissipation effect of the humidifier shell 1, thereby increasing the humidification efficiency of the humidifier shell 1. Both ends of the humidifier shell 1 are fixed with mounting plate edges 2, and the two sealing covers 3 are respectively sleeved on one end of the humidifier shell 1; it also includes a fixing mechanism, which is installed on the two mounting plate edges 2 and is used to connect and fix the mounting plate edges 2 and the sealing cover 3. The sealing cover 3 is provided with a sleeve notch 11 on one side facing the mounting plate edge 2, and a sleeve groove 13 is provided on the sealing cover 3. The sealing cover 3 can slide down from the top of the mounting plate edge 2 and be sleeved on the mounting plate edge 2. A pair of insertion holes 5 are provided at the bottom end of the sealing cover 3 and close to the sleeve notch 11.

[0021] The fixing mechanism includes a bidirectional threaded rod 10 rotatably mounted between the two mounting plate edges 2, and a movable long plate 7 is screwed on the left and right threads of the bidirectional threaded rod 10. Since the two movable long plates 7 are screwed on the left and right threads of the bidirectional threaded rod 10 respectively, when the bidirectional threaded rod 10 rotates, the two movable long plates 7 can be forced to approach or move away from each other at the same time. The divergent surfaces of the two movable long plates 7 are fixed with an insertion square rod 8, and the insertion square rod 8 can pass through the through hole 12 and be inserted in the insertion hole 5. It can be known from the above that the insertion square rod 8 The square rod 8 can be inserted into the insertion hole 5 at the same time to play a limiting role, or can be moved out of the insertion hole 5 at the same time to release the limit. A pair of guide rods 6 are also fixed between the two mounting plate edges 2. The two guide rods 6 are respectively located on one side of the two-way threaded rod 10. The two guide rods 6 both penetrate the movable long board 7 and are slidably connected to the movable long board 7. The guide rods 6 can enable the two movable long boards 7 to move stably, avoiding the movable long boards 7 from rotating with the two-way threaded rod 10 due to the friction of the rotation, thereby realizing the smooth movement function of the movable long board 7.

[0022] In this embodiment, if Figure 2 and Figure 3 As shown, a pair of through holes 12 are opened at the bottom end of the mounting plate edge 2. When the mounting plate edge 2 and the sealing cover 3 are aligned with each other, the through holes 12 correspond horizontally to the insertion holes 5. The insertion square rod 8 first passes through the through holes 12 and then is inserted into the insertion hole 5, so that the mounting plate edge 2 and the sealing cover 3 are relatively limited to prevent the sealing cover 3 from sliding, thereby realizing the fixing function.

[0023] In this embodiment, if Figures 1 to 3As shown, one end of the bidirectional threaded rod 10 passes through the edge 2 of the mounting plate and is connected and fixed with a manual knob 4. A U-shaped opening 9 is provided at the bottom end of the sealing cover 3 close to the manual knob 4. The connecting portion between the bidirectional threaded rod 10 and the manual knob 4 is located in the U-shaped opening 9. Since the manual knob 4 is located on the outside of the sealing cover 3, when the sealing cover 3 is slidably installed, as the sealing cover 3 continues to move, the connecting portion between the bidirectional threaded rod 10 and the manual knob 4 will automatically embed into the U-shaped opening 9, thereby avoiding interference with the normal use of the manual knob 4 and the normal installation of the sealing cover 3, thereby facilitating the realization of the assembly mechanism.

[0024] The implementation principle of a hydrogen fuel cell humidifier box body of the present application embodiment is as follows: during assembly, firstly, the manual knob 4 is turned counterclockwise to move the two movable long plates 7 away from the respective adjacent mounting plate edges 2 to ensure that the inserted square rod 8 is on the outside of the through hole 12, and then, the sealing cover 3 is lifted to make the sleeve notch 11 align with the upper part of the mounting plate edge 2 and slide down, and when the sealing cover 3 cannot be moved down further, it indicates that the sleeve connection is completed at this time, and at the same time, the through hole 12 corresponds horizontally to the insertion hole 5, and then, the manual knob 4 is turned clockwise, and the two movable long plates 7 are respectively moved close to the respective adjacent mounting plate edges 2, until the inserted square rod 8 is moved out of the insertion hole 5, or the movable long plates 7 are fitted with the mounting plate edge 2 to complete the assembly;

[0025] By providing a socket groove 13 on the sealing cover 3 which can be slidably sleeved on the mounting plate edge 2 of the humidifier shell 1, the sealing cover 3 of the closed humidifier shell 1 can be tightly connected with the humidifier shell, and the sealing cover 3 and the mounting plate edge 2 are limited from below by the provided manual knob 4, bidirectional threaded rod 10, movable long plate 7, inserted square rod 8, through hole 12, inserted hole 5 and guide rod 6, so that the sealing cover 3 cannot slide on the mounting plate edge 2, thereby increasing the installation stability. During the installation process, the staff only needs to slide the sealing cover 3 on the mounting plate edge 2, and then turn the manual knob 4 to realize the installation operation, which avoids the traditional need to screw and fix multiple bolts, resulting in a large amount of labor and low assembly efficiency, thereby improving practicality.
