[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-7 As shown, this utility model provides a technical solution:

[0024] The enclosure includes a housing 1. A protective frame 2 is fixedly connected to one side of the housing 1, and a cooling fan 3 is fixedly connected to the other side of the housing 1. A second protective frame 4 is fixedly connected to one side of the cooling fan 3. A cooling pipe 5 is installed inside the housing 1. Multiple pairs of semi-circular pipes 6 are movably mounted on the cooling pipe 5. Multiple heat sinks 7 are rotatably connected to each semi-circular pipe 6. A support block 8 is fixedly connected to the bottom of each semi-circular pipe 6, and a connecting plate 9 is fixedly connected to the top of each semi-circular pipe 6. A fixing component is installed on the connecting plate 9. Both ends of the cooling pipe 5 penetrate the housing 1 and are fixedly connected to it. Connecting flanges 18 are installed at both ends of the cooling pipe 5. One end of the cooling pipe 5 is connected to the hydrogen compressor output pipe through the connecting flange 18, allowing high-temperature, high-pressure hydrogen gas to enter the cooling pipe 5 and cool. The other end of the cooling pipe 5 is connected to the hydrogen delivery pipe through the connecting flange 18. The heat of the hydrogen is first transferred to the semi-circular pipe 6 through the cooling pipe 5, and then to the heat sink 7 through the semi-circular pipe 6. The cooling fan 3 is started to make the air flow, blow the heat sink 7, and reduce the temperature of the heat sink 7, thereby cooling the hydrogen in the hydrogen compressor. The protective frame 1 2 and the protective frame 2 4 can be used to protect the staff and the structure inside the box 1. The pair of semi-circular pipes 6 can be separated by loosening the fixing components. The outer side of the semi-circular pipe 6 is provided with an arc-shaped slide rail, and the inner side of the heat sink 7 is provided with a slide groove that matches the arc-shaped slide rail. After the semi-circular pipes 6 are separated, each heat sink 7 can be rotated off from the semi-circular pipe 6, which facilitates the replacement of the heat sink 7 and can also reduce costs.

[0025] The fixing assembly includes a housing 10, which is fixedly connected to the top of the connecting plate 9. A pair of limiting rods 11 are fixedly connected to the top of the housing 10. Each limiting rod 11 is fitted with a spring 12 around its outer periphery. A fixing block 13 is movably disposed at the bottom of each limiting rod 11. A handle 14 is fixedly connected to the top of the fixing block 13. A through-hole is opened on one side of the housing 10, and the handle 14 is adapted to the through-hole. A sliding groove is opened on the top of the connecting plate 9, and the fixing block 13 is slidably connected to the sliding groove. A slot 15 is opened on one side of the connecting plate 9, and a buckle 16 is fixedly connected to one side of the connecting plate 9. When the semicircular tubes 6 are attached, the connecting plates 9 at the top of the semicircular tubes 6 are also attached to each other, so that the buckle 16 on one of the connecting plates slides into the slot 15 on the other connecting plate. The spring 12 pushes the fixing block 13 to fix the buckle 16. When it is necessary to separate the pair of semicircular tubes 6, the handle 14 at the top of the pair of semicircular tubes 6 is pulled upward at the same time, which causes the fixing block 13 to slide upward in the groove at the top of the connecting plate 9. The spring 12 is further compressed, so that the buckle 16 is released and the pair of semicircular tubes 6 are separated, which makes it easier to maintain and clean the heat sink 7 on the semicircular tubes 6.

[0026] Multiple support plates 17 are fixedly connected to the cooling pipe 5. When a pair of semi-circular pipes 6 are fixedly attached, the support block 8 at the bottom of the semi-circular pipe 6 contacts the top of the support plate 17. The support plate 17 can prevent the semi-circular pipe 6 from sliding down the cooling pipe 5 due to gravity.

[0027] The working principle of this utility model is as follows:

[0028] One end of the cooling pipe 5 is connected to the hydrogen compressor output pipe through the connecting flange 18, allowing high-temperature and high-pressure hydrogen to enter the cooling pipe 5. The other end of the cooling pipe 5 is connected to the hydrogen delivery pipe through the connecting flange 18. The heat of the hydrogen is first transferred to the semi-circular pipe 6 through the cooling pipe 5, and then transferred to the heat sink 7 through the semi-circular pipe 6. The cooling fan 3 is started to make the air flow, blow the heat sink 7, and reduce the temperature of the heat sink 7, thereby cooling the hydrogen in the hydrogen compressor. The protective frame 1 2 and the protective frame 2 4 can be used to protect the staff and the structure inside the box 1.

[0029] When a pair of semicircular tubes 6 are attached, the connecting plates 9 at the top of the semicircular tubes 6 are also attached to each other, so that the buckle 16 on one of the connecting plates slides into the slot 15 on the other connecting plate. The spring 12 pushes the fixing block 13 to fix the buckle 16. When it is necessary to separate the pair of semicircular tubes 6, the handle 14 at the top of the pair of semicircular tubes 6 is pulled upward at the same time, which causes the fixing block 13 to slide upward in the groove at the top of the connecting plate 9. The spring 12 is further compressed, so that the buckle 16 is released and the pair of semicircular tubes 6 are separated, which makes it easier to maintain and clean the heat sink 7 on the semicircular tubes 6.

[0030] An arc-shaped slide rail is provided on the outer side of the semi-circular tube 6, and a sliding groove adapted to the arc-shaped slide rail is provided on the inner side of the heat sink 7. After the semi-circular tube 6 is separated, each heat sink 7 can be rotated off the semi-circular tube 6, which facilitates the replacement of the heat sink 7 and can also reduce costs.

[0031] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
