Description

Technical Field

[0001] This utility model relates to the field of fuel cell stack technology, specifically to an air-cooled fuel cell stack support device with a reinforced structure. Background Technology

[0002] A fuel cell stack is a device composed of multiple individual fuel cells connected in series. It is mainly used to directly convert chemical energy into electrical energy and is the core component of a fuel cell system.

[0003] According to announcement number CN212033158U, a fixed structure and fuel cell stack device are disclosed. The fixed structure includes a housing with a closed cavity inside for housing the fuel cell stack; multiple support bars spaced apart at the bottom of the housing for supporting the fuel cell stack; and multiple brackets fixed to the housing for defining the horizontal position of the fuel cell stack. When the fuel cell stack is located in the closed cavity, the brackets contact the sidewalls of the fuel cell stack. The fixed structure and fuel cell stack provided by this invention can effectively support the fuel cell stack, preventing misalignment or collapse of the middle section of the fuel cell stack under complex driving conditions.

[0004] The aforementioned fixed structures can improve the overall strength of the fuel cell stack. However, during the use of the fuel cell stack, heat is generated and stored inside the casing, which leads to an increase in overall temperature and reduces the service life of the fuel cell stack.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind-cooled fuel cell stack support device with a reinforced structure, comprising a housing, an air inlet on one side of the bottom of the housing, a grid mesh inside the air inlet, a connecting frame fixedly connected to the bottom of the air inlet, a connecting bracket fixedly connected to one side of the connecting frame, a motor fixedly connected to the side of the connecting bracket away from the connecting frame, multiple adjusting blades rotatably connected inside the connecting frame, a rotating shaft fixedly connected inside the adjusting blades, a rotating wheel fixedly sleeved on the surface of the rotating shaft, and a toothed belt meshing on the surface of the rotating wheel.

[0007] As a further preferred embodiment of this technical solution, multiple longitudinal reinforcing ribs are evenly distributed along the horizontal direction on the front and rear sides of the shell, and multiple transverse reinforcing ribs are provided between the upper and lower frames of the shell.

[0008] As a further preferred embodiment of this technical solution, two support plates are symmetrically welded to the inner sides of the housing, and multiple positioning posts are fixedly connected to the top of the support plates.

[0009] As a further preferred embodiment of this technical solution, the interior of the housing is provided with multiple rubber pads, an air guide channel is formed between two adjacent rubber pads, and a fuel cell stack is provided on top of the rubber pads.

[0010] As a further preferred embodiment of this technical solution, the fuel cell stack is symmetrically provided with fixing plates on both sides, and the bottom of the fixing plate is provided with multiple positioning holes, which are adapted to the positioning posts. The fixing plates are fixedly installed on the top of the support plate by connecting bolts.

[0011] As a further preferred embodiment of this technical solution, a cover plate is fixedly connected to the top of the housing, and an air outlet is provided on one side of the top of the cover plate, with a second grille mesh installed inside the air outlet.

[0013] This utility model provides a wind-cooled fuel cell stack support device with a reinforced structure, which has the following advantages:

[0014] (1) By setting an air inlet at the bottom of the housing, the present invention allows outside air to enter the housing through the air inlet.

[0015] (2) In this utility model, the starting motor drives the rotating shaft and the adjusting blade to rotate. Since the rotating shaft surface of multiple adjusting blades is fixedly fitted with a rotating wheel, and multiple rotating wheels are connected by a toothed belt, the power is transmitted to other rotating wheels through the toothed belt while one adjusting blade rotates, so as to drive other adjusting blades to rotate, thereby controlling the distance between two adjacent adjusting blades and adjusting the air intake to meet the different working conditions of the fuel cell stack.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figures 1 to 6 As shown in this embodiment, an air-cooled fuel cell stack support device with a reinforced structure includes a housing 1. An air inlet 2 is provided on one side of the bottom of the housing 1. A grid mesh 3 is provided inside the air inlet 2. A connecting frame 4 is fixedly connected to the bottom of the air inlet 2. A connecting bracket 5 is fixedly connected to one side of the connecting frame 4. A motor 6 is fixedly connected to the side of the connecting bracket 5 away from the connecting frame 4. Multiple adjusting blades 7 are rotatably connected inside the connecting frame 4. A rotating shaft 8 is fixedly connected inside the adjusting blades 7. A rotating wheel 9 is fixedly sleeved on the surface of the rotating shaft 8. A toothed belt 10 is engaged on the surface of the rotating wheel 9.

[0025] By setting an air inlet 2 at the bottom of the housing 1, outside air can enter the housing 1 through the air inlet 2, thereby ensuring normal air circulation and carrying away the heat generated by the operation of the fuel cell stack 16. A grid mesh 3 is set inside the air inlet 2 to prevent foreign objects from entering. The motor 6 is started, and its output shaft drives the rotating shaft 8 and the adjusting blades 7 to rotate. Since the rotating shaft 8 of multiple adjusting blades 7 is fixedly fitted with a rotating wheel 9, and the multiple rotating wheels 9 are connected by a toothed belt 10, the power is transmitted to other rotating wheels 9 through the toothed belt 10 while one adjusting blade 7 is rotating, so as to drive other adjusting blades 7 to rotate. This controls the distance between two adjacent adjusting blades 7 and adjusts the air intake to meet the different operating conditions of the fuel cell stack 16.

[0026] Multiple longitudinal reinforcing ribs 12 are evenly distributed along the horizontal direction on the front and rear sides of the shell 1. Multiple transverse reinforcing ribs 11 are provided between the upper and lower frames of the shell 1. The transverse reinforcing ribs 11 and the longitudinal reinforcing ribs 12 are intersected and connected to form a grid-like reinforcement structure.

[0027] By setting multiple longitudinal stiffeners 12 and transverse stiffeners 11 on the front and rear sides of the housing 1, the longitudinal stiffeners 12 enhance the bending strength of the housing 1 in the vertical direction, preventing the housing 1 from deforming when subjected to the weight of the battery stack or other vertical loads. The transverse stiffeners 11 improve the tensile and compressive strength of the housing 1 in the horizontal direction, enhancing the stability of the entire support device and preventing the housing 1 from twisting or shaking when subjected to lateral forces.

[0028] Two support plates 13 are symmetrically welded to the inside of the shell 1, and multiple positioning posts 14 are fixedly connected to the top of the support plates 13.

[0029] The interior of the housing 1 is provided with multiple rubber pads 15, and an air guide channel is formed between two adjacent rubber pads 15. The top of the rubber pads 15 is provided with a fuel cell stack 16.

[0030] The fuel cell stack 16 is symmetrically provided with fixing plates 17 on both sides. The bottom of the fixing plate 17 is provided with multiple positioning holes 18, which are compatible with the positioning posts 14. The fixing plate 17 is fixedly installed on the top of the support plate 13 by connecting bolts 19.

[0031] Positioning posts 14 are set on the support plate 13 and correspond to the positioning holes 18 on the fixing plate 17, so as to play a role in precise positioning when the fuel cell stack 16 is installed. Multiple rubber pads 15 are set at the bottom of the fuel cell stack 16, which can support it and reduce the impact between the fuel cell stack 16 and the shell 1 during operation, reduce the noise generated by vibration, and improve the stability and reliability of the entire system.

[0032] A cover plate 20 is fixedly connected to the top of the housing 1. An air outlet is provided on one side of the top of the cover plate 20, and a grille 21 is provided inside the air outlet.

[0033] A connecting frame 22 is fixedly connected to the bottom of the grid mesh 21. A mounting plate 23 is fixedly connected to the inner wall of the connecting frame 22. A motor 24 is fixedly connected to the top of the mounting plate 23. A cooling fan 25 is fixedly connected to the output shaft of the motor 24. The cooling fan 25 is located at the bottom of the mounting plate 23.

[0034] The start motor 24 drives the cooling fan 25 to work, thereby accelerating the airflow inside the housing 1, allowing the air to move through the air duct and carrying away the heat generated during operation, thus ensuring that the fuel cell stack 16 is in a normal temperature environment and improving its service life.

[0035] This utility model provides a wind-cooled fuel cell stack support device with a reinforced structure, the specific working principle of which is as follows:

[0036] In use, the fuel cell stack 16 is placed on the rubber pad 15, the positioning holes 18 on the fixing plate 17 are aligned with the positioning posts 14, and the fixing plate 17 is installed on the positioning posts 14. At this time, the bottom of the fixing plate 17 is in contact with the support plate 13, and the side of the fixing plate 17 is in contact with the fuel cell stack 16. The positions of the fixing plate 17, the fuel cell stack 16 and the support plate 13 are fixed by the connecting bolts 19. When the fuel cell stack 16 is working, outside air is allowed to enter the interior of the housing 1 through the air inlet 2. At the same time, the motor 24 drives the cooling fan 25 to work, thereby accelerating the air flow inside the housing 1, allowing the air to move through the air guide channel, and carrying away the heat generated during operation, thereby achieving air cooling and ensuring that the fuel cell stack 16 is in a normal temperature environment.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
