The first embodiment of the solid hydrogen storage container of the present invention is shown in fig. 1 and 2, and comprises a container body 10, an end cap 20, a liquid inlet 32, a liquid outlet 31, an air inlet 41 and an air outlet 42.
Regarding the container main body 10, a plurality of hydrogen storage pipelines 11 and a plurality of cooling pipelines 12 are arranged in the container main body 10, the hydrogen storage pipelines 11 and the cooling pipelines 12 both link up two opposite ends of the container main body 10, the plurality of hydrogen storage pipelines 11 are connected and conducted, and each hydrogen storage pipeline 11 is at least arranged adjacent to one cooling pipeline 12.
Specifically, nine hydrogen storage pipelines 11 are provided, four cooling pipelines 12 are provided, the nine hydrogen storage pipelines 11 are arranged in a matrix in a nine-grid shape, and each cooling pipeline 12 is arranged between the four hydrogen storage pipelines 11, so that the purpose of radiating heat by using one cooling pipeline 12 as the four hydrogen storage pipelines 11 is realized; the arrangement mode has the advantages that the structural compactness among the pipelines can be improved, the arrangement quantity of the cooling pipelines 12 is reduced as far as possible, if more schemes of the hydrogen storage pipelines 11 need to be designed in the future, the requirement that the plurality of hydrogen storage pipelines 11 are arranged in a matrix arrangement mode is met, at least part of the cooling pipelines 12 are arranged in a mode of being adjacent to the four hydrogen storage pipelines 11 at the same time, and the same beneficial effect can be obtained.
Of course, the arrangement of the hydrogen storage pipes 11 and the cooling pipes 12 is not limited to the above example, as shown in fig. 3, in this case, four hydrogen storage pipes 11 and three cooling pipes 12 are provided, and the hydrogen storage pipes 11 and the cooling pipes 12 are alternately arranged from left to right, so that the hydrogen storage pipes 11 and the cooling pipes 12 are uniformly arranged on the same plane; as shown in fig. 4, two hydrogen storage pipelines 11 are arranged above and side by side, two cooling pipelines 12 are arranged below and side by side, and each hydrogen storage pipeline 11 is respectively arranged adjacent to one cooling pipeline 12 from top to bottom; that is, the arrangement of the hydrogen storage pipe 11 and the cooling pipe 12 may be adjusted by those skilled in the art according to specific requirements.
In addition, the connection and conduction among the hydrogen storage pipelines 11 have various implementation manners, for example, a connection pipeline can be arranged in the container main body 10, and two ends of the connection pipeline are respectively connected and conducted with the two hydrogen storage pipelines 11, so that the connection pipeline is prevented from being connected with the cooling pipeline 12 in a staggered manner.
However, in order to simplify the internal structure of the container main body 10, two adjacent hydrogen storage pipelines 11 may be arranged side by side, a through hole 13 is formed on the pipe wall of each hydrogen storage pipeline 11, and the through holes 13 connect and conduct the adjacent hydrogen storage pipelines 11; specifically, in the horizontal direction, the through hole 13 connects and conducts the hydrogen storage pipes 11 on the left and right sides, in the vertical direction, the through hole 13 conducts the hydrogen storage pipes 11 on the upper and lower sides, and at the moment, the hydrogen storage pipes 11 on the second row are only needed to be conducted up and down, so that the mutual conduction among nine hydrogen storage pipes 11 can be realized, and the number of the through holes 13 is reduced.
Regarding the end caps 20, the end caps 20 are mounted at two opposite ends of the container body 10, the surface of the end cap 20 facing the container body 10 is provided with a flow guide channel 21, the flow guide channel 21 is not communicated with the hydrogen storage pipeline 11, and two opposite ends of each cooling pipeline 12 are respectively communicated with the flow guide channels 21 on the end caps 20, so that the cooling pipelines 12 are communicated with each other.
Specifically, at this time, the setting track of the flow guide channel 21 should bypass the hydrogen storage pipeline 11, which makes the flow guide channel 21 and the hydrogen storage pipeline 11 not opposite to each other, and then the flow guide channel 21 and the hydrogen storage pipeline 11 are not communicated with each other after the end of the hydrogen storage pipeline 11 is capped by the surface of the end cap 20.
Since the cooling pipes 12 are connected and communicated through the flow guide passage 21, when the cooling pipes 12 are filled with cooling liquid, the cooling liquid can circulate among the cooling pipes 12, thereby cooling and radiating the hydrogen storage pipes 11.

However, it should be noted that the liquid inlet 32 and the liquid outlet 31 are not necessarily respectively disposed on the two end caps 20, even if the liquid inlet 32 and the liquid outlet 31 are both disposed on the same end cap 20, because both ends of each cooling pipeline 12 are communicated with the flow guide channels 21 on the two end caps 20, the liquid inlet 32 can still convey the cooling liquid to each cooling pipeline 12, and the liquid outlet 31 can still extract the cooling liquid from each cooling pipeline 12 for output, that is, only the liquid inlet 32 needs to be connected and communicated with one of the flow guide channels 21, and the liquid outlet 31 is communicated with the same or the other flow guide channel 21, so that the normal flow of the cooling liquid can be realized.
Regarding the gas inlet 41 and the gas outlet 42, in this embodiment, the gas inlet 41 and the gas outlet 42 are respectively disposed on the two end caps 20, and the gas inlet 41 and the gas outlet 42 are respectively connected and conducted with different hydrogen storage pipelines 11, because the hydrogen storage pipelines 11 are conducted with each other, the hydrogen gas input through the gas inlet 41 can inevitably flow into each hydrogen storage pipeline 11 for storage, and the hydrogen gas stored in each hydrogen storage pipeline 11 can also inevitably be output through the gas outlet 42.
However, it should be noted that the gas inlet 41 and the gas outlet 42 are not necessarily connected and conducted with different hydrogen storage pipelines 11, for example, the gas inlet 41 and the gas outlet 42 may be connected and conducted with two opposite ends of the same hydrogen storage pipeline 11, at this time, the hydrogen gas input through the gas inlet 41 can still be conveyed into each hydrogen storage pipeline 11, the hydrogen gas stored in each hydrogen storage pipeline 11 can still be output through the gas outlet 42, that is, only the gas inlet 41 needs to be connected and conducted with one of the hydrogen storage pipelines 11, and the gas outlet 42 is conducted with the same or another hydrogen storage pipeline 11, so that the normal circulation of the hydrogen gas can be realized.
It is right when solid-state hydrogen storage container uses, hydrogen stores in 41 inputs to each hydrogen storage pipeline 11 through the air inlet, or hydrogen in the hydrogen storage pipeline 11 exports through gas outlet 42, because the coolant liquid is inputed to each cooling tube 12 in through inlet 32 to export through liquid outlet 31, the coolant liquid can in time be discharged after absorbing the heat of hydrogen storage pipeline 11 promptly, in time with guaranteeing the radiating.
