Detailed Embodiments

[0027] The following will further describe in detail the embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0028] As Figures 1 to 3As shown in the figure, an embodiment of the first aspect of the present utility model provides a heat dissipation bracket for a stack, which includes a bottom bracket 100, a middle bracket 102, a first leg 108, and a second leg 112; the middle bracket 102 is installed on the bottom bracket 100, and at the top of the middle bracket, there is a first cushion block 104 for supporting the stack and a second cushion block 106 for supporting the radiator; the first leg 108 is arranged on the first side of the bottom bracket 100 to support the stack, and at the top of the first leg 108, there is a third cushion block 110; the second leg 112 is arranged on the second side of the bottom bracket 100 to support the radiator, and at the top of the second leg 112, there is a fourth cushion block 114, and the first side and the second side of the bottom bracket 100 are oppositely arranged.

[0029] According to the heat dissipation bracket for a stack provided by the embodiment of the first aspect of the present utility model, through the combined design of the bottom bracket 100, the middle bracket 102, the first leg 108, and the second leg 112, the stack and the radiator are stably supported. This structure can effectively prevent the stack and the radiator from shaking or displacing during operation, ensuring the stability and safety of the equipment. The second cushion block 106 for supporting the radiator arranged on the middle bracket 102, and the fourth cushion block 114 arranged on the second leg 112 provide a stable support platform for the radiator. This design helps the radiator better play its heat dissipation function, ensuring that during the operation of the stack, the space between the middle bracket 102 and the bottom bracket 100 can be used for exhaust heat dissipation, thereby enabling the stack to maintain a relatively low temperature, thus improving the working efficiency and lifespan of the stack. The stack and the radiator are respectively supported by the first leg 108 and the second leg 112, and cushion blocks are arranged at the top of the legs, making the installation and disassembly processes of the stack and the radiator simple and convenient. This design reduces the maintenance cost of the equipment and improves the maintainability of the equipment. The design of this heat dissipation bracket has a certain generality and can be applicable to stacks and radiators of different specifications and models. This design makes the heat dissipation bracket have strong compatibility and can meet the actual needs of different users.

[0030] Please continue to refer to Figures 1 to 3 , the bottom bracket 100, as the basic structure of the entire heat dissipation bracket, bears the middle bracket 102, the first leg 108, and the second leg 112, ensuring that they can be stably placed on the ground or other supporting surfaces.

[0031] The middle bracket 102 is installed on the bottom bracket 100, and there are two cushion blocks with different functions at its top. First is the first cushion block 104, which is used to directly support the stack, ensuring that the stack can be placed stably on the bracket. Second is the second cushion block 106, which is designed to support the radiator, enabling the radiator to form an effective heat dissipation channel with the stack and improving the heat dissipation efficiency.

[0032] The first leg 108 is located on one side of the bottom bracket 100, and its main function is to provide additional support to the fuel cell stack. At the top of the first leg 108, a third cushion block 110 is provided, which functions to ensure that the fuel cell stack will not be damaged when being supported and to increase the stability of the fuel cell stack.

[0033] The second leg 112 corresponds to the first leg 108. The second leg 112 is located on the other side of the bottom bracket 100 and is mainly used to support the radiator. At the top of the second leg 112, a fourth cushion block 114 is provided. Acting together with the second cushion block 106, it ensures that the radiator is stably placed on the bracket and prevents the radiator from displacing or vibrating during operation.

[0034] Through the combined design of the bottom bracket 100, the middle bracket 102, the first leg 108 and the second leg 112, this heat dissipation bracket provides stable support for the fuel cell stack and the radiator, effectively preventing displacement or damage caused by vibration or external force; it can also provide stable support for the radiator, while optimizing the heat dissipation channels, making the heat transfer between the fuel cell stack and the radiator more efficient, thereby improving the heat dissipation effect; the design of this heat dissipation bracket is reasonable and the structure is simple, making the installation and disassembly process of the fuel cell stack and the radiator simple and fast. At the same time, due to the firm connection between components, the maintenance cost caused by loosening or damage is also reduced. In addition, by setting multiple cushion blocks, this heat dissipation bracket effectively reduces the friction and collision between the fuel cell stack and the radiator and the bracket, thereby reducing the risk of damage caused by friction or collision. At the same time, the cushion blocks also have a certain buffering effect, which can, to a certain extent, protect the fuel cell stack and the radiator from external force impact.

[0035] According to an embodiment of the present utility model, a first support beam 116 and a second support beam 118 are further provided on the bottom bracket 100, and the first support beam 116 and the second support beam 118 are respectively connected to the middle bracket 102.

[0036] See Figure 1 and Figure 2 , in an embodiment of the present utility model, the heat dissipation bracket for the fuel cell stack is further optimized on the basis of the original design. On the bottom bracket 100, a first support beam 116 and a second support beam 118 are newly added, and these two support beams are respectively connected to the middle bracket 102.

[0037] The first support beam 116 and the second support beam 118 are respectively installed on the bottom bracket 100 and are connected to the middle bracket 102. Their addition further strengthens the connection stability between the middle bracket 102 and the bottom bracket 100, and improves the rigidity and stability of the entire heat dissipation bracket. The first support beam 116 and the second support beam 118 can be designed and arranged according to actual needs to maximize their support effect.

[0038] By adding the first support beam 116 and the second support beam 118, the connection between the middle bracket 102 and the bottom bracket 100 is strengthened, making the structure of the entire heat dissipation bracket more stable. This design effectively prevents displacement or damage caused by vibration or external forces, improving the reliability of the heat dissipation bracket. The addition of the first support beam 116 and the second support beam 118 increases the rigidity of the heat dissipation bracket, making the entire bracket less likely to deform or twist when bearing the weight of the fuel cell stack and the radiator. This helps to keep the fuel cell stack and the radiator stably placed and also improves the heat dissipation effect.

[0039] According to an embodiment of the present invention, a third support beam 120 is further provided on the bottom bracket 100. The third support beam 120 is connected to the middle bracket 102. The first support beam 116, the second support beam 118, and the third support beam 120 are used to limit the degrees of freedom of the middle bracket 102 in space.

[0040] See Figure 1 and Figure 2 In the embodiment of the present invention, the first support beam 116, the second support beam 118, and the third support beam 120 are respectively installed on the bottom bracket 100 and are tightly connected to the middle bracket 102. The arrangement of the first support beam 116, the second support beam 118, and the third support beam 120 not only strengthens the connection between the middle bracket 102 and the bottom bracket 100, but more importantly, through the stable support of three points, the degrees of freedom of the middle bracket 102 in space are effectively limited. This means that when the middle bracket 102 is subjected to external forces, its displacement and deformation will be greatly limited, thus ensuring the stable placement of the fuel cell stack and the radiator.

[0041] By adding the third support beam 120 and acting together with the original first support beam 116 and second support beam 118, the degrees of freedom of the middle bracket 102 in space are greatly limited. This design makes the structure of the heat dissipation bracket more stable when bearing the weight of the fuel cell stack and the radiator, and is not likely to deform or displace. Thus, the stable placement and efficient heat dissipation of the fuel cell stack and the radiator are ensured. The reasonable layout and design of the three support beams significantly improve the load-bearing capacity of the heat dissipation bracket. Even under high load or complex working conditions, the heat dissipation bracket can maintain stable performance.

[0042] According to an embodiment of the present invention, the bottom bracket 100 includes a frame body 122, and a reinforcing beam 124 is provided inside the frame body 122.

[0043] See Figure 1 and Figure 3 In a specific embodiment of the present invention, the bottom bracket 100 is designed to include a frame body 122, and a reinforcing beam 124 is provided inside the frame body 122.

[0044] The housing 122 serves as the basic structure of the bottom bracket 100, providing a stable framework to support components such as the middle bracket 102, the first leg 108, the second leg 112, and possibly support beams. The housing 122 can be rectangular, square, or other shapes, depending on the overall design and application requirements of the heat dissipation bracket.

[0045] The reinforcing beam 124 is located inside the housing 122 and is used to further enhance the structural strength of the bottom bracket 100. The reinforcing beam 124 can be horizontal, vertical, or diagonal, and it is connected to the housing 122 to form a more stable overall structure. The design and material selection of the reinforcing beam 124 should take into account factors such as the load-bearing capacity, stability, and durability of the heat dissipation bracket.

[0046] According to an embodiment of the present utility model, a reinforcing plate 125 is provided between the reinforcing beam 124 and the housing 122.

[0047] See Figure 1 and Figure 3 , the reinforcing plate 125 is a connecting member provided between the reinforcing beam 124 and the housing 122. It can be a flat plate or a plate-like structure with a specific shape, used to enhance the connection strength between the two. The reinforcing plate 125 can be made of the same material as the housing 122 and the reinforcing beam 124, or a material with higher strength or better corrosion resistance can be selected. The reinforcing beam 124, as a part of the bottom bracket 100, mainly plays a role in enhancing the structural strength of the bottom bracket 100. It usually extends along a certain direction of the housing 122 and is connected to the housing 122. The reinforcing beam 124 and the housing 122 together constitute the main structure of the bottom bracket 100, providing stable support for the entire heat dissipation bracket.

[0048] By providing the reinforcing plate 125 between the reinforcing beam 124 and the housing 122, the structural strength of the entire heat dissipation bracket is significantly improved. The presence of the reinforcing plate 125 increases the connection area between the reinforcing beam 124 and the housing 122, making the connection between the two more firm and reliable. This helps to improve the load-bearing capacity and stability of the heat dissipation bracket, ensuring its stable performance under various working conditions.

[0049] The introduction of the reinforcing plate 125 enhances the stability of the bottom bracket 100. It can effectively prevent the relative displacement or deformation of the reinforcing beam 124 and the housing 122 when subjected to external forces, thus maintaining the stability and reliability of the entire heat dissipation bracket. This is of great significance for protecting the stack and radiator from the effects of vibration and shock.

[0050] According to an embodiment of the present utility model, a first mounting hole for passing a fastener is provided on the frame body 122 and / or the reinforcing beam 124, and the bottom bracket 100 is adapted to be mounted on the vehicle body through the fastener.

[0051] The first mounting hole mentioned here can be a threaded hole, a clearance hole, etc., and the fastener can be a bolt, a screw, etc. The vehicle body can be the vehicle body of an electric vehicle or the vehicle body of a rail vehicle. Taking the bolt and the rail vehicle as an example, the bolt passes through the first mounting hole and is correspondingly mounted on the rail vehicle, thereby achieving the purpose of mounting the heat dissipation bracket of the fuel cell stack on the rail vehicle.

[0052] According to an embodiment of the present utility model, a reserved mounting hole is further provided on the frame body 122 and / or the reinforcing beam 124.

[0053] In the embodiment of the present utility model, the number of the reserved mounting holes depends on the specific installation requirements and the number of connection points, and may be one or more. The size of the reserved mounting hole needs to be determined according to the size of the fastener or the connecting piece to ensure that the fastener can pass through smoothly and be fixed firmly. The reserved mounting hole is used for connecting with other devices, such as a temperature detection piece, a controller, etc.

[0054] According to an embodiment of the present utility model, a first positioning member 126 for positioning the fuel cell stack and a second positioning member 128 for positioning the radiator are further provided on the top of the middle bracket 102.

[0055] Through the arrangement of the first positioning member 126 and the second positioning member 128, the middle bracket 102 can provide a high-precision positioning function for the fuel cell stack and the radiator, ensure the correct relative position relationship between the two, thereby improving the heat dissipation efficiency and reducing the performance loss caused by the position deviation. This design can also simplify the installation process, reduce the installation time, and lower the installation difficulty.

[0056] According to an embodiment of the present utility model, a second mounting hole 130 for mounting the fuel cell stack is provided on the top of the middle bracket 102 and the top of the first leg 108, and a third mounting hole 132 for mounting the radiator is provided on the top of the middle bracket 102 and the top of the second leg 112.

[0057] As Figure 1 shown, a second mounting hole 130 is provided on the top of the middle bracket 102, and these holes are used for mounting the fuel cell stack. The number and position of the holes are determined according to the size and installation requirements of the fuel cell stack to ensure that the fuel cell stack can be placed on the bracket smoothly and accurately. Similarly, on the top of the middle bracket 102, a third mounting hole 132 is further provided, and these holes are used for mounting the radiator. The radiator is usually located above the fuel cell stack, so the position and number of these holes need to match the mounting holes of the fuel cell stack to form an effective heat dissipation channel.

[0058] Similar to the middle bracket 102, a second mounting hole 130 is also provided at the top of the first leg 108. The second mounting hole 130 corresponds to the mounting hole on the middle bracket 102 and is used to further fix the fuel cell stack, enhancing the stability of the entire mounting structure. A third mounting hole 132 is provided at the top of the second leg 112, and the third mounting hole 132 is used to fix the radiator. Radiators usually require additional support to maintain their stability and heat dissipation effect. Therefore, the setting of these mounting holes is crucial.

[0059] An embodiment of the second aspect of the present utility model provides a vehicle, including the above-mentioned heat dissipation bracket for the fuel cell stack.

[0060] According to the vehicle provided by the embodiment of the second aspect of the present utility model, since the vehicle is equipped with the above-mentioned heat dissipation bracket, it can effectively dissipate heat from the fuel cell stack, ensuring that the fuel cell stack maintains a relatively low temperature during operation. This is of great significance for improving the working efficiency of the fuel cell stack, extending its service life, and ensuring the stability of the overall performance of the vehicle. The stable structural design of the heat dissipation bracket not only ensures the stable operation of the fuel cell stack and the radiator, but also enhances the overall structural stability of the vehicle. This helps to reduce equipment damage or failures caused by vehicle vibrations or other external factors, improving the safety and reliability of the vehicle. The compact design of the heat dissipation bracket can reasonably utilize the internal space of the vehicle, enabling key components such as the fuel cell stack and the radiator to be installed orderly and compactly inside the vehicle. This not only optimizes the space layout of the vehicle, but also improves the space utilization rate of the vehicle. Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
