When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific implementation manners and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] In the present utility model, the so-called "first" and "second" do not represent specific quantities and orders, but are only used for name distinction.

[0039] On the one hand, as Figure 1 and Figure 2 , Figure 3 , Figure 4 shown, a pipeline structure in an embodiment of the present utility model includes a water pipe assembly 1 and an air pipe assembly 2; the water pipe assembly 1 includes a water inlet unit 11, a water distribution unit 12, a cooling unit 13 and a water outlet unit 14 arranged in sequence, the water inlet unit 11 includes a water inlet pipe 111, the water outlet unit 14 includes a water outlet pipe 141 arranged parallel to the water inlet pipe 111, and the cooling unit 13 includes a first cooling group 131 and a second cooling group 132 respectively arranged on both sides of the water inlet pipe 111; the air pipe assembly 2 includes an air inlet unit 21, an air distribution unit 22, a conveying unit 23 and an air outlet unit 24 arranged in sequence, the air inlet unit 21 includes an air inlet pipe 211, the air outlet unit 24 includes an air outlet pipe 241 arranged parallel to the air inlet pipe 211, and the conveying unit 23 includes a first conveying group 231 and a second conveying group 232 arranged on both sides of the air inlet pipe 211.

[0040] The above-mentioned pipeline structure is compact and occupies a small volume by centrally arranging the water inlet unit 11, the water outlet unit 14, the air inlet unit 21 and the air outlet unit 24 in the middle of the entire pipeline structure and arranging the cooling unit 13 and the conveying unit 23 on both sides of the entire pipeline structure.

[0041] In one embodiment, the first cooling group 131 includes a plurality of cooling pipes 133 arranged in parallel on the same vertical plane, with adjacent cooling pipes 133 connected end-to-end. This tooth-like connection of the cooling pipes 133 improves vertical space utilization of the cooling unit 13, resulting in a compact structure and reduced floor space.

[0042] In one embodiment, the first cooling group 131 includes at least six cooling pipes 133 arranged in parallel. In this way, the cooling efficiency of the cooling unit 13 can be guaranteed by a sufficient number of cooling pipes 133.

[0043] In one embodiment, the first delivery assembly 231 includes a delivery air pipe 233, the cooling portion of which is disposed within the cooling pipe 133. Thus, a water pump is used to pump cooling water from the water inlet pipe 111 into the cooling pipe 133. The flowing cooling water quickly removes heat generated by the compression of hydrogen in the delivery air pipe 233, and the heat is then removed from the water outlet pipe 141 along with the flowing water.

[0044] In one embodiment, the air pipe assembly 2 further includes a filter unit 25, which is disposed at the air inlet of the air inlet unit 21. Thus, the filter unit 25 filters out moisture and other particulate impurities in the hydrogen, thereby ensuring the safety of the pipeline structure and the hydrogen compressor and extending their service life.

[0045] On the other hand, Figure 1 and Figure 2 、 Figure 3 、 Figure 4 As shown, a hydrogen compressor in one embodiment of the present invention includes a mounting base 3, a hydraulic device 4 and a pipeline structure 5; the hydraulic device 4 includes a hydraulic component 41 and a compression component 42; the compression component 42 is connected to the delivery unit 23 and is used to compress the hydrogen in the delivery unit 23; the hydraulic component 41 is used to provide hydraulic power for the compression component 42.

[0046] In one embodiment, the hydraulic component 41 includes a hydraulic support 411, a hydraulic oil tank 412, and a hydraulic pump 413 arranged below the hydraulic support 411; the compression component 42 includes a hydraulic cylinder 421 connected to the hydraulic pump 413 through a hydraulic pipe 43, and the hydraulic cylinder 421 is arranged on the hydraulic support 411; the hydraulic pump 413 pumps the hydraulic oil in the hydraulic oil tank 412 to the hydraulic cylinder 421, and the hydraulic cylinder 421 compresses hydrogen through the cylinder piston rod and passes the hydrogen into the delivery unit 23.

[0047] In one embodiment, the first cooling group 131 and the second cooling group 132 are respectively disposed on both sides of the hydraulic support 411. Specifically, the hydraulic component 41 includes two hydraulic pumps 413, the compression component 42 includes two hydraulic cylinders 421, and a third cooling group is disposed between the two hydraulic pumps 413.

[0048] In one embodiment, the hydraulic device 4 further includes a hydraulic control block 44; the pipeline structure 5, hydraulic control block 44, and hydraulic oil tank 412 are sequentially arranged on the mounting base 3 from left to right; the communication ports of the water inlet unit 11 and the water outlet unit 14 are both arranged on the left side of the mounting base 3; and the connection ports of the air inlet unit 21 and the air outlet unit 24 are both arranged on the left side of the mounting base 3. Thus, by arranging the communication ports of the water inlet unit 11 and the water outlet unit 14, and the connection ports of the air inlet unit 21 and the air outlet unit 24 on the left side of the mounting base 3, it is convenient for operators to uniformly connect the hydrogen compressor, facilitating subsequent installation and use.

[0049] In one embodiment, the hydraulic device 4 includes a bleed pipe 45 for discharging gas from the hydraulic pump 413. This allows the bleed pipe 45 to expel air from the hydraulic pump 413 when the hydraulic pump 413 is operational. Furthermore, during maintenance, the bleed pipe 45 can be used to discharge hydrogen from the hydraulic pump 413, preventing the formation of explosive mixed gases within the pump that could cause a safety hazard.

[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 implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
