[0002] Hydrogen compressors are commonly used equipment for hydrogen compression. They compress and transport the gas by changing its volume. Like other gases, hydrogen can be pressurized using a centrifugal compressor to meet process requirements. In each typical application, the type of compressor used is determined by the hydrogen flow rate and the required pressure increase. Circulating hydrogen compressors use centrifugal compressors.

[0003] The Chinese utility model patent with publication number CN221823998U discloses a hydrogen compressor, which relates to the field of hydrogen compression equipment. The compressor includes a compressor body, a hydrogen storage tank and a purification device, including a heat dissipation device, which is arranged on one side of the compressor body. The heat dissipation device includes a control box and a heat dissipation fan, which is arranged on the control box and electrically connected to the heat dissipation fan.

[0004] However, the cooling fan in the above-mentioned hydrogen compressor is only attached to the control box, and the heat is blown to the compressor body by the wind through the suction principle, without considering the heat dissipation efficiency of other components, which is not conducive to maintaining a suitable operating temperature for the hydrogen compressor as a whole.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0036] On the one hand, if Figure 1 and Figure 2 As shown, a heat dissipation device in one embodiment of the present invention includes:

[0037] The first heat dissipation component 1 is used for dissipating heat from the hydraulic components;

[0038] The second heat dissipation component 2 is used to dissipate heat from the compressed gas;

[0039] The third heat dissipation component 3 is used to dissipate heat for the electrical cabinet components, and includes a fan assembly 31 arranged along one side of the length direction of the electrical cabinet, and a wind shield assembly 32 arranged along the length direction of the electrical cabinet, with the air outlet of the fan assembly 31 facing the electrical cabinet components.

[0040] The above-mentioned heat dissipation device directs the air flow toward the electrical cabinet components through the air outlet of the fan assembly 31 and cooperates with the wind shield assembly 32 to guide the air flow. The air intake of the fan assembly 31 can absorb a large amount of cold air and blow it toward the electrical cabinet components, thereby taking away the heat generated by the electrical cabinet, and the heat dissipation efficiency is high; at the same time, the hydraulic components and compressed gas are cooled by the first heat dissipation component 1 and the second heat dissipation component 2 respectively, so that the hydrogen compressor as a whole maintains a suitable operating temperature and ensures working efficiency.

[0041] In one embodiment, the wind shield assembly 32 includes a first baffle 33 and a second baffle 34, respectively disposed on either side of the electrical cabinet. Thus, the first baffle 33 and the second baffle 34 form a stable air blowing space, and the wind pressure generated by the fan assembly 31 drives the heat generated by the electrical cabinet away from the hydrogen compressor.

[0042] In one embodiment, the first baffle 33 is provided with an inclined windshield portion that is inclined inwardly along the length of the electrical cabinet. Thus, the inclined windshield portion that is inclined inwardly along the length of the electrical cabinet can reduce the cross-sectional area through which air flows, thereby gradually accelerating ventilation and heat dissipation.

[0043] In one embodiment, the wind shielding inclined portion is inclined by 5° to 15° along the length direction of the electrical cabinet.

[0044] On the other hand, Figure 1 and Figure 2 、 Figure 3 、 Figure 4 As shown, a hydrogen compression device in one embodiment of the present invention includes a compression body 4 and a heat dissipation device; the compression body 4 includes a base frame 5, and a hydraulic component 6, a compression component 7, and an electrical cabinet component 8 arranged on the base frame 5; the first heat dissipation component 1 is used to dissipate heat for the hydraulic component 6, the second heat dissipation component 2 is used to dissipate heat for the compressed gas compressed by the compression component 7, and the third heat dissipation component 3 is used to dissipate heat for the electrical cabinet component 8.

[0045] In one embodiment, the electrical cabinet component is arranged in the middle of the base frame 5, the hydraulic component 6 is arranged on the rear side of the electrical cabinet component 8, and the second heat dissipation component 2 is arranged below the electrical cabinet component 8; the fan assembly 31 is arranged on the left side of the electrical cabinet component 8, and the first heat dissipation component 1 is arranged on the right side of the hydraulic component 6.

[0046] In one embodiment, the hydraulic component 6 includes a hydraulic support 61, a hydraulic oil tank 62 mounted on the hydraulic support 61, and a hydraulic pump 63 disposed below the hydraulic oil tank 62. The compression component 7 includes a hydraulic cylinder 71 connected to the hydraulic pump 63 via a hydraulic pipeline. The hydraulic pump 63 pumps hydraulic oil from the hydraulic oil tank 62 into the hydraulic cylinder 71. The hydraulic cylinder 71 compresses hydrogen through a piston rod and passes the hydrogen into the second heat dissipation component 2. The first heat dissipation component 1 includes an air cooling assembly 11, which is used to cool the hydraulic oil in the hydraulic oil tank 62. In this way, the fan assembly 31 blows heat from the electrical cabinet component 8 toward the air cooling assembly 11. The fan assembly 31 and the air cooling assembly 11 cooperate to accelerate the heat dissipation wind speed. At the same time, the windshield assembly 32 can guide the blowing direction.

[0047] In one embodiment, the compression component 7 is used to compress hydrogen introduced through the inlet pipe 701 and pass the compressed hydrogen into the outlet pipe 702. The second heat dissipation component 2 includes a water inlet pipe 21, a cooling pipe unit 22, and a water outlet pipe 23, which are sequentially connected. The outlet pipe 702 is disposed within the cooling pipe unit 22. Thus, a water pump is used to pass cooling water from the water inlet pipe 21 into the cooling pipe of the cooling pipe unit 22. The flowing cooling water quickly removes the heat generated by the compression of the hydrogen, and the heat is then removed from the water outlet pipe 23 along with the flowing water.

[0048] In one embodiment, the cooling pipe unit 22 includes a plurality of cooling pipes arranged in parallel on the same vertical plane, with adjacent cooling pipes connected end-to-end. Specifically, the cooling pipe unit 22 includes at least six cooling pipes arranged in parallel. This tooth-like connection of the cooling pipes improves vertical space utilization within the cooling pipe unit 22, resulting in a compact structure and reduced floor space. Furthermore, a sufficient number of cooling pipes ensures the cooling efficiency of the cooling pipe unit 22.

[0049] In one embodiment, the compression component 7 further includes an oil collection unit 72 disposed below the hydraulic cylinder 71. This oil collection unit 72 includes an oil collection box for collecting leaked oil from the hydraulic cylinder. Because the hydraulic oil pressure in the hydraulic cylinder 71 is high, a small amount of hydraulic oil may leak during long-term use. By providing an oil leak hole in the hydraulic cylinder 71 to release some of the excess pressure and hydraulic oil, safe operation is ensured. Thus, the oil collection unit 72 collects leaked hydraulic oil from the hydraulic cylinder 71, preventing waste and environmental pollution, and promoting energy conservation and environmental protection.

[0050] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
