Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
A first embodiment of the solid hydrogen storage vessel of the present invention is shown in fig. 1 and 2 and includes a vessel 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 body 10, a plurality of hydrogen storage pipelines 11 and a plurality of cooling pipelines 12 are arranged in the container body 10, the hydrogen storage pipelines 11 and the cooling pipelines 12 are communicated with opposite ends of the container body 10, the 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, at this time, the number of the hydrogen storage pipelines 11 is nine, the number of the cooling pipelines 12 is four, the nine hydrogen storage pipelines 11 are arranged in a matrix form and are arranged in a nine-grid form, and each cooling pipeline 12 is arranged among the four hydrogen storage pipelines 11, so that the purpose of radiating heat for the four hydrogen storage pipelines 11 by one cooling pipeline 12 is realized; the arrangement has the advantages that the compactness of the structure among the pipelines can be improved, the number of the cooling pipelines 12 is reduced as much as possible, if more schemes of the hydrogen storage pipelines 11 are needed to be designed later, the plurality of the hydrogen storage pipelines 11 are arranged in a matrix arrangement, 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 effects 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, and as shown in fig. 3, at this time, the number of the hydrogen storage pipes 11 is four, the number of the cooling pipes 12 is three, 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 side by side above, two cooling pipelines 12 are arranged side by side below, and each hydrogen storage pipeline 11 is respectively arranged adjacent to one cooling pipeline 12 up and down; i.e. the manner in which the hydrogen storage conduit 11 and the cooling conduit 12 are arranged can be adapted by a person skilled in the art according to the specific requirements.
In addition, the connection between the plurality of hydrogen storage pipelines 11 has various implementation manners, for example, a connecting pipeline can be arranged in the container main body 10, two ends of the connecting pipeline are respectively connected and communicated with the two hydrogen storage pipelines 11, and at the moment, the connecting pipeline and the cooling pipeline 12 can be only required to be prevented from being connected 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, and through holes 13 are formed in the 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 holes 13 connect and conduct the hydrogen storage pipelines 11 on the left and right sides of the through holes, in the vertical direction, the through holes 13 conduct the hydrogen storage pipelines 11 on the upper and lower sides of the through holes, and at the moment, only the second row of hydrogen storage pipelines 11 are required to conduct vertically, so that the mutual conduction among the nine hydrogen storage pipelines 11 can be realized, and the setting number of the through holes 13 is reduced.
Regarding the end caps 20, the end caps 20 are mounted at opposite ends of the container body 10, the surface of the end caps 20 facing the container body 10 is provided with a flow guiding channel 21, the flow guiding channel 21 is not communicated with the hydrogen storage pipeline 11, and opposite ends of each cooling pipeline 12 are respectively communicated with the flow guiding channels 21 on the end caps 20, so that the cooling pipelines 12 are connected and communicated.
Specifically, the setting track of the flow guiding channel 21 should bypass the hydrogen storage pipeline 11 at this time, which will make the flow guiding channel 21 and the hydrogen storage pipeline 11 not opposite to each other, and then after the port of the hydrogen storage pipeline 11 is capped by the surface of the end cover 20, the flow guiding channel 21 and the hydrogen storage pipeline 11 are not communicated with each other.
Since the plurality of cooling pipes 12 are connected and conducted by the diversion channels 21, when the cooling pipes 12 are filled with the cooling liquid, the cooling liquid can circulate between the cooling pipes 12, thereby realizing cooling and heat dissipation of the plurality of hydrogen storage pipes 11.
Regarding the liquid inlet 32 and the liquid outlet 31, in this embodiment, the liquid inlet 32 is connected to the flow guiding channel 21 on one end cap 20, and the liquid outlet 31 is connected to the flow guiding channel 21 on the other end cap 20, and the cooling liquid input through the liquid inlet 32 can be necessarily output through the liquid outlet 31 because the cooling pipeline 12 realizes the connection of the flow guiding channels 21 on the two end caps 20.
However, it should be noted that the liquid inlet 32 and the liquid outlet 31 are not necessarily disposed on the two end caps 20, even though the liquid inlet 32 and the liquid outlet 31 are disposed on the same end cap 20, since both ends of each cooling pipe 12 are conducted with the flow guiding channels 21 on the two end caps 20, the liquid inlet 32 still can convey cooling liquid to each cooling pipe 12, and the liquid outlet 31 still can extract cooling liquid from each cooling pipe 12 for output, that is, only the connection and conduction between the liquid inlet 32 and one of the flow guiding channels 21 is ensured, and the liquid outlet 31 is conducted with the same or the other flow guiding channel 21, so that the normal circulation of the cooling liquid can be realized.
Regarding the air inlet 41 and the air outlet 42, in this embodiment, the air inlet 41 and the air outlet 42 are respectively provided on the two end caps 20, and the air inlet 41 and the air outlet 42 are respectively connected and conducted with different hydrogen storage pipelines 11, and since the hydrogen storage pipelines 11 are conducted mutually, the hydrogen input through the air inlet 41 can necessarily flow into each hydrogen storage pipeline 11 for storage, and the hydrogen stored in each hydrogen storage pipeline 11 can also necessarily be output through the air outlet 42.
However, it should be noted that the air inlet 41 and the air outlet 42 are not necessarily connected and conducted with different hydrogen storage pipelines 11, for example, the air inlet 41 and the air outlet 42 may be connected and conducted with two opposite ends of the same hydrogen storage pipeline 11, at this time, the hydrogen input through the air inlet 41 may still be conveyed into each hydrogen storage pipeline 11, and the hydrogen stored in each hydrogen storage pipeline 11 may still be output through the air outlet 42, that is, only the connection and conduction between the air inlet 41 and one of the hydrogen storage pipelines 11 is ensured, and the air outlet 42 is conducted with the same or another hydrogen storage pipeline 11, so that the normal circulation of the hydrogen may be realized.
When the solid hydrogen storage container is applied, hydrogen is input into each hydrogen storage pipeline 11 through the air inlet 41 for storage, or hydrogen in the hydrogen storage pipeline 11 is output through the air outlet 42, and cooling liquid is input into each cooling pipeline 12 through the liquid inlet 32 and output through the liquid outlet 31, namely the cooling liquid can be timely discharged after absorbing heat of the hydrogen storage pipeline 11, so that heat dissipation is timely ensured.
Compared with the prior art, the cooling and storing structure is arranged in the container main body 10, the welding part is only between the end cover 20 and the container main body 10, the number of parts and the welding part are greatly reduced, the production difficulty is reduced, the sealing performance is improved, the safety coefficient of the solid hydrogen storage container is improved, the solid hydrogen storage container is convenient to maintain and overhaul in the future, and important assistance is brought to the development of the solid hydrogen storage technology.
A second embodiment of the solid hydrogen storage vessel according to the present invention is shown in fig. 5, which differs from the first embodiment in that the cooling pipe 12 includes a main cooling pipe 121 and a sub cooling pipe 122, the main cooling pipe 121 being disposed adjacent to four hydrogen storage pipes 11 at the same time, the sub cooling pipe 122 being disposed adjacent to the outer surface of the vessel body 10, and the sub cooling pipe 122 being disposed adjacent to two hydrogen storage pipes 11 at the same time.
Specifically, at this time, the number of the hydrogen storage pipelines 11 is nine, the number of the main cooling pipelines 121 is four, the number of the auxiliary cooling pipelines 122 is eight, the four main cooling pipelines 121 are arranged at the internal gaps of the nine hydrogen storage pipelines 11, and the eight auxiliary cooling pipelines 122 are adjacently arranged outside the eight hydrogen storage pipelines 11.
The arrangement has the advantages that each cooling pipeline 12 can be ensured to radiate heat of the two hydrogen storage pipelines 11, and the multi-side simultaneous radiation of the hydrogen storage channels is realized on the premise that the number of the cooling pipelines 12 is not greatly increased or reduced.
