Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy generator technology, specifically to a heat dissipation component suitable for hydrogen energy generators. Background Technology

[0002] A hydrogen generator is a device that uses hydrogen as fuel to convert chemical energy into electrical energy through electrochemical or thermodynamic cycles. The entire process produces only water vapor and no pollutants such as CO2 or sulfides. However, when a hydrogen generator is working, its internal power generation equipment, such as fuel cell stacks and inverters, will generate a lot of heat. If the heat cannot be dissipated in time, it will lead to a decline in equipment performance or even failure.

[0003] Referring to the patent document: Patent Publication No. CN117174950A, Patent Publication Date 2023-12-05, a hydrogen fuel cell engine main cycle heat dissipation integrated structure in the field of engine technology is disclosed. It includes a base, a connecting ring, an engine body, a first radiator, a second radiator, a first condenser pipe, and a second condenser pipe. A partition and a grid are fixedly connected inside the base. The first and second condenser pipes are both located at the upper end of the partition, and the first and second radiators are both located at the upper end of the grid. The connecting ring is fixedly connected to the upper end of the base, and the engine body is fixedly inserted into the connecting ring. With dual radiators, it has good heat dissipation effect and high efficiency. The liquid storage layer, cooling layer, and heat dissipation layer within the base are progressively layered, thereby dissipating heat from the engine body at the upper end of the base, reducing the impact of the large space occupied by the radiator on engine operation.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Traditional hydrogen generator cooling systems typically involve creating ventilation holes on one side of the generator's outer casing and adding a cooling fan to cool the internal power generation equipment. However, this method is ineffective and fails to provide targeted, rapid airflow for cooling based on the heat generated by the internal power generation equipment. Consequently, some high-heat-generating components cannot be effectively cooled. Furthermore, when the hydrogen generator is not in operation, electrostatic adsorption allows a large amount of dust to enter through the ventilation holes and adhere to the inside of the power generation equipment, reducing its heat dissipation efficiency.

[0006] Therefore, this utility model provides a heat dissipation component suitable for hydrogen energy generators. Utility Model Content

[0007] To address the problems of poor cooling performance, inability to target specific heat dissipation, and the tendency for dust to enter the generator housing during shutdown due to electrostatic adsorption, thus affecting the equipment's heat dissipation efficiency, this utility model aims to provide a heat dissipation component suitable for hydrogen generators.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation component for a hydrogen energy generator, comprising a hydrogen energy generator housing, wherein heat dissipation mechanisms are provided at the center of both sides of the hydrogen energy generator housing for cooling the power generation equipment inside the housing, and the heat dissipation mechanisms include:

[0009] The adjustment assembly includes two outer frames fixedly installed inside the hydrogen generator housing. Multiple louvers with equal spacing are rotatably installed in the middle of the two outer frames. Gears are fixedly installed in the middle of the bottom of the multiple louvers. Toothed plates are provided at the bottom of the two outer frames. Both toothed plates are meshed with the gears. Electric push rods are provided on one side of the two toothed plates. The drive ends of the two electric push rods are fixedly installed in the middle of one side of the toothed plates.

[0010] The mounting components are located on both sides of the center of the hydrogen generator housing, allowing for quick installation and removal of its dustproof panels.

[0011] Preferably, the mounting assembly includes annular frames fixedly installed in the middle of both sides of the hydrogen generator housing. Cooling fans that cooperate with each other are provided in the middle of the two annular frames. Limiting rings are provided on one side of each of the two annular frames. Dustproof plates are provided in the middle of one side of each of the two annular frames. A set of locking blocks is fixedly installed on the outer side of each of the two dustproof plates. Both sets of locking blocks are slidably locked in the middle of the limiting rings. Two symmetrically distributed bolts are provided on one side of each of the two dustproof plates.

[0012] Preferably, a cover is fixedly installed on the lower part of both outer frames, a bracket is fixedly installed on the middle part of one side of both covers, and two electric push rods are fixedly installed on the upper part of the brackets, with the driving end of the electric push rods passing through the middle part of one side of the brackets.

[0013] Preferably, a sliding rod is fixedly installed in the middle of each of the two covers, and the two toothed plates are slidably installed in the middle of the sliding rod.

[0014] Preferably, the outer side of the dustproof plate is fixedly installed with multiple handles arranged in a circular array, and the outer side of each handle is provided with anti-slip texture.

[0015] Preferably, the two sets of locking blocks are provided with threaded grooves at the corresponding positions of the bolts, and the corresponding position of the middle part of the limiting ring is provided with a through hole, and the bolts are sequentially threaded through the through holes and installed in the middle of the threaded grooves. Beneficial effects

[0016] This invention provides a heat dissipation component suitable for hydrogen fuel cell generators. Compared with existing technologies, it has the following advantages:

[0017] 1. This application uses an electric actuator to drive a toothed plate to move laterally along a sliding rod, which in turn drives multiple sets of louvers to deflect synchronously via gear meshing, thereby adjusting the air intake angle and opening / closing range. This allows for dynamic adjustment of the louver opening direction based on changes in the internal temperature of the power generation equipment, thus altering the airflow direction. Simultaneously, the air convection formed by the cooling fans on both sides enables rapid cooling of electrical components in different parts. Furthermore, when the equipment is not in operation, the louvers close under the drive of the electric actuator to form a sealed cavity, preventing dust from entering the hydrogen energy generator casing due to static electricity or other reasons, causing it to adhere to the outer surface of electrical components, reducing heat dissipation, and accelerating equipment aging.

[0018] 2. This application uses a sliding snap-fit ​​positioning of a locking block and a limiting ring, and a bolt is screwed into the threaded groove after passing through the hole of the limiting ring to achieve fixation, so as to achieve quick disassembly and assembly of the dust cover. During maintenance, only two bolts need to be loosened to rotate the dust cover to complete the disassembly task, which effectively avoids the problem of traditional fixed methods or the use of multiple bolts to tighten the dust cover around the circumference, which makes it inconvenient to disassemble, clean and replace it.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a heat dissipation component suitable for hydrogen energy generators, including a hydrogen energy generator housing 1, with heat dissipation mechanisms 2 provided at the center of both sides of the hydrogen energy generator housing 1 for cooling the power generation equipment inside the hydrogen energy generator housing 1. The heat dissipation mechanism 2 includes:

[0028] The regulating assembly 21 includes two outer frames 211 fixedly installed inside the hydrogen generator housing 1. Multiple louvers 212, evenly spaced, are rotatably mounted on the center of each outer frame 211. These louvers 212 are made of aerospace-grade aluminum alloy with an anodized surface to enhance thermal conductivity, while also being lightweight and corrosion-resistant. The multiple louvers 212, angled to different sides, can adjust the airflow direction, thereby targeting and cooling different electrical components to prevent excessive heat generation in certain areas and maintain overall equipment operating efficiency. Furthermore, rubber sealing strips are embedded along the edges of the louvers 212. When the louvers are closed, the rubber sealing strips contact each other, achieving a good sealing effect and preventing... Dust enters the hydrogen generator housing 1. Gears 217 are fixedly installed at the bottom center of multiple louvers 212. Toothed plates 216 are provided at the bottom of the two outer frames 211. The two toothed plates 216 are meshed with the gears 217. Electric actuators 214 are provided on one side of the two toothed plates 216. The drive ends of the two electric actuators 214 are fixedly installed at the center of one side of the toothed plate 216. The electric actuator 214 is a 20mm diameter, 24V waterproof pen-type miniature electric actuator, model SD50. The control system of the electric actuator 214 is connected to the control system of the electrical components inside the hydrogen generator housing 1 to control the start, stop and extension length of the electric actuator 214, thereby controlling the deflection angle of the louvers 212.

[0029] Mounting components 22 are located on the middle of both sides of the hydrogen generator housing 1 for quick installation and removal of its dustproof panels 223.

[0030] The mounting assembly 22 includes annular frames 221 fixedly installed in the middle of both sides of the hydrogen generator housing 1. Each of the two annular frames 221 has a cooling fan 222 that works in conjunction with each other. One side of the cooling fan 222 blows air into the hydrogen generator housing 1, while the other side draws air from the hydrogen generator housing 1 and blows it outwards, creating convection currents within the hydrogen generator housing 1, accelerating airflow, and thus improving heat dissipation efficiency. Each of the two annular frames 221 has a limiting device on one side. The ring 224 has a U-shaped cross-section and multiple notches on its outer edge face to facilitate the insertion of the locking block 225 on the dustproof plate 223 into the middle of the U-shaped structure of the limiting ring 224. Dustproof plates 223 are provided on the middle of one side of each of the two annular frames 221. A set of locking blocks 225 is fixedly installed on the outer side of each of the two dustproof plates 223. Both sets of locking blocks 225 are slidably locked in the middle of the limiting ring 224. Two symmetrically distributed bolts 226 are provided on one side of each of the two dustproof plates 223.

[0031] A cover 213 is fixedly installed on the lower part of each of the two outer frames 211. A bracket 215 is fixedly installed on the middle of one side of each of the two covers 213. Two electric push rods 214 are fixedly installed on the upper part of the bracket 215, and the driving end of the electric push rod 214 passes through the middle of one side of the bracket 215. The lower cover 213 is used to isolate the electric push rod 214, the toothed plate 216 and the gear 217 from the electrical components inside the hydrogen energy generator housing 1 to prevent the circuits from intersecting. At the same time, a linear bearing is installed at the position where the bracket 215 passes through the driving end of the electric push rod 214, and the driving end of the electric push rod 214 is slidably locked in the middle of the linear bearing.

[0032] A sliding rod 2161 is fixedly installed in the middle of each of the two covers 213, and two toothed plates 216 are slidably installed in the middle of the sliding rod 2161. The cross section of the sliding rod 2161 is a regular hexagonal structure, which can ensure that the toothed plate 216 slides stably on its upper part while preventing the toothed plate 216 from rotating and affecting the meshing effect between the gear 217 and the toothed plate 216.

[0033] Multiple handles 2231 arranged in a ring array are fixedly installed on the outer side of the dustproof plate 223, and the outer side of each handle 2231 is provided with anti-slip texture. The handles 2231 are designed to facilitate the rotation of the dustproof plate 223 by holding the handles 2231 when the locking block 225 enters the middle of the U-shaped structure of the limiting ring 224, so that the locking block 225 is aligned with the outer end face.

[0034] The two sets of locking blocks 225 and the bolts 226 have threaded grooves 2261 at the corresponding positions. The corresponding position of the middle part of the limiting ring 224 has a through hole. The bolts 226 pass through the through hole in sequence and are threaded in the middle of the threaded grooves 2261. The installation of the bolts 226 can fix and limit the dustproof plate 223.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0036] During operation, when the power generation equipment inside the hydrogen energy generator housing 1 generates heat and requires heat dissipation adjustment, the electric actuator 214 is activated. Its drive end pushes the toothed plate 216 to slide on the sliding rod 2161. Since the toothed plate 216 meshes with the gear 217, the movement of the toothed plate 216 drives the gear 217 to rotate, thereby causing the louvered plate 212 to rotate around the outer frame 211. This allows the angles of multiple louvered plates 212 to be adjusted synchronously, opening them up. The electric actuator 214 can drive the louvered plate 212 to change its deflection direction, thereby changing the direction of the incoming airflow. This allows for adjustment of the airflow direction according to the heat generation of different parts of the internal equipment, resulting in better heat dissipation. When heat dissipation is not required, the electric actuator 214 will drive multiple louvered plates 212 to deflect simultaneously and contact each other, creating a sealed environment inside the hydrogen energy generator housing 1.

[0037] When the louvers 212 are opened to dissipate heat, the cooling fan 222 in the middle of the annular frame 221 is powered on and rotates at high speed. When one cooling fan 222 rotates, it draws in outside air from the outside of the dustproof plate 223, passes through the annular frame 221, and blows it into the hydrogen energy generator housing 1. The other cooling fan 222 rotates in the opposite direction, so that it blows the hot air inside the hydrogen energy generator housing 1 out through the gap between the louvers 212 and exhausts the heat generated inside the hydrogen energy generator housing 1 through the exhaust hole of the dustproof plate 223.

[0038] When installing the dustproof plate 223, align the dustproof plate 223 with the notch of the limiting ring 224, so that the locking block 225 enters the middle of the limiting ring 224. At this time, rotate the dustproof plate 223 so that the locking block 225 slides into the locking groove of the limiting ring 224. At this time, the through hole and the threaded groove 2261 are aligned and connected. By passing the bolt 226 through the through hole and threading it into the threaded groove 2261, it can be fixed.
