Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen storage, in particular to a hydrogen storage device with a heat exchange function. Background Art

[0002] With the development of society, hydrogen energy, as a clean and efficient secondary energy source, has received people's attention and extensive research, and has become an ideal energy source for humanity in the future. The storage and transportation of hydrogen are key technologies in the utilization of hydrogen energy. At present, there are mainly three ways to store hydrogen. One is to store compressed hydrogen in gas cylinders, the disadvantages of which are high cylinder pressure, high danger, and limited storage capacity of a single cylinder; the second is to store cooled and liquefied hydrogen in storage tanks, the disadvantages of which are complex cryogenic liquefaction process, high requirement for the heat insulation performance of the storage tank, and low hydrogen storage efficiency; the third is to use an active alloy hydrogen absorption material to make a container for storage. This method has a large hydrogen storage volume density, simple operation, convenient transportation, low cost, and high safety, and is currently the most promising hydrogen storage method.

[0003] However, during the hydrogen absorption and desorption process of the container made of active alloy, certain heat will be released and absorbed, and these heats need to be regulated by an external heat exchange device. Otherwise, the hydrogen absorption and desorption efficiency will be reduced. The traditional process is to insert heat exchange tubes into the hydrogen storage device, but it is very difficult for the external heat management system to increase the flow rate of the medium fluid, resulting in low heat exchange efficiency, very inconvenient operation, and unable to meet the usage requirements of storing hydrogen.

[0004] Therefore, it is urgent to develop a hydrogen storage device with a heat exchange function to solve the technical problem of low heat exchange efficiency of the existing hydrogen storage device. Summary of the Utility Model

[0063] Embodiment 5:

[0064] This embodiment provides a hydrogen storage device with a heat exchange function.

The heat exchange module 2 includes a U-shaped pipe assembly 21, a first grid plate 22, a second grid plate 23, and a third grid plate 24. The U-shaped pipe assembly 21 is located in the housing 1. The first grid plate 22, the second grid plate 23, and the third grid plate 24 are installed on the U-shaped pipe assembly 21. The first grid plate 22 and the second grid plate 23 are respectively installed on both sides of the U-shaped pipe assembly 21, and the third grid plates 24 are evenly and staggeredly distributed in the middle part of the U-shaped pipe assembly 21.

A hydrogen storage cavity is formed between the inner side wall of the housing 1 and the outer side wall of the heat exchange module 2, and the hydrogen storage cavity is used for introducing and discharging hydrogen.

[0065] Specifically, the hydrogen storage device is composed of a housing 1, a heat exchange module 2, a medium interface 3, and a hydrogen interface 4. The housing 1 is a container made of an active alloy and is used to store hydrogen. During the hydrogen absorption and release process, the housing 1 will release and absorb a certain amount of heat, and this heat needs to be regulated by an external heat exchange device, otherwise the hydrogen absorption and release efficiency will be reduced. The heat exchange module 2 in this embodiment is composed of a U-shaped pipe assembly 21, a first grid plate 22, a second grid plate 23, and a third grid plate 24. The wall surface of the heat exchange module 2 enclosed in the housing 1 is a wall-type heat exchange device serving as a heat transfer surface. The medium fluid for heat exchange flows inside the pipe, while hydrogen flows outside the pipe. To improve the heat transfer coefficient of hydrogen outside the pipe, in this embodiment, a number of third grid plates 24 are installed in the housing 1. The third grid plates 24 can increase the hydrogen fluid velocity, forcing hydrogen to pass horizontally through the heat exchange module 2 multiple times along a specified path, enhancing the turbulence degree of the medium fluid.

[0066] The medium interface 3 is connected to the U-shaped pipe assembly 21, so that the medium fluid can be input into or output from the U-shaped pipe assembly 21 through the medium interface 3. The hydrogen interface 4 is connected to the housing 1 and is in communication with the interior of the housing 1. In this way, heat exchange can occur between the hydrogen stored in the housing 1 and the U-shaped pipe assembly 21, thereby realizing the temperature regulation of hydrogen, and further regulating the hydrogen absorption and release rate of the housing 1.

[0067] The housing 1 of this embodiment includes a housing body 11, a housing cap 12, and a seal 13. The housing cap 12 is connected to the opening side of the housing body 11, and an internal space is formed by the housing body 11 and the housing cap 12. The seal 13 is installed at the installation joint of the housing body 11 and the housing cap 12 to achieve a sealed connection between the housing body 11 and the housing cap 12. Specifically, the housing body 11 is a circular cylinder structure, and the housing cap 12 is sealed and connected to the opening side of the housing body 11 through the seal 13 (such as an O-ring) and fastening connectors (such as conventional screws, nuts, etc.), thereby forming a sealed container for storing hydrogen.

[0068] The first grid plate 22 of this embodiment is a circular partition plate, which is installed on the side of the housing body 11 close to the housing cap 12; the second grid plate 23 is a waist-shaped partition plate, which is installed on the side of the housing body 11 far from the housing cap 12. Specifically, the U-shaped pipe assembly 21 includes a number of first U-shaped pipes 211, second U-shaped pipes 212, third U-shaped pipes 213, and fourth U-shaped pipes 214 arranged horizontally and in parallel. The lengths of the first U-shaped pipe 211, second U-shaped pipe 212, third U-shaped pipe 213, and fourth U-shaped pipe 214 increase in sequence, and the inlets and outlets of the first U-shaped pipe 211, second U-shaped pipe 212, third U-shaped pipe 213, and fourth U-shaped pipe 214 are uniformly inserted on the first grid plate 22, and the bottoms of the first U-shaped pipe 211, second U-shaped pipe 212, third U-shaped pipe 213, and fourth U-shaped pipe 214 are all sleeved and inserted on the second grid plate 23.

[0069] Specifically, the first grid plate 22 and the second grid plate 23 are used to fixedly support and connect the U-shaped pipe assembly 21. The first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214 are evenly distributed and installed on the first grid plate 22 and the second grid plate 23. Since the lengths of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214 gradually increase, the first U-shaped pipe 211 is located inside the second U-shaped pipe 212 during installation, the second U-shaped pipe 212 is located inside the third U-shaped pipe 213, and the third U-shaped pipe 213 is located inside the fourth U-shaped pipe 214. Considering that hydrogen needs to be introduced into the interiors of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214, in this embodiment, the inlets and outlets of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214 are evenly inserted on the first grid plate 22 to facilitate the inflow and outflow of the medium fluid, while the second grid plate 23 is used to support the bottoms of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214, so that the U-shaped pipe assembly 21 can conduct sufficient heat exchange with the external hydrogen.

The inlets of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214 are all located in the upper space, and the outlets of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213, and the fourth U-shaped pipe 214 are all located in the lower space, thereby making the inflow and outflow of the medium fluid smoother.

[0071] The heat exchange module 2 of this embodiment further includes a number of connecting rods 25 evenly distributed and connected between the first grid plate 22 and the second grid plate 23, and the connecting rods 25 are inserted through the third grid plate 24. Thus, through the setting of the connecting rods 25, the stable connection of the U-shaped pipe assembly 21 is realized.

The medium fluid is introduced into the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213 and the fourth U-shaped pipe 214 through the medium inlet valve 31. The medium outlet valve 32 is connected to the outlets of the first U-shaped pipe 211, the second U-shaped pipe 212, the third U-shaped pipe 213 and the fourth U-shaped pipe 214. The internal space between the shell cap 12 and the first grid plate 22 is divided into two by the setting of the partition plate 5, so that the input and output of the medium fluid can be separated and will not affect each other.

[0073] The hydrogen interface 4 of this embodiment includes a hydrogen inlet valve 41 and a hydrogen outlet valve 42, which are installed on the shell body 11. The hydrogen inlet valve 41 is located at the top of the shell body 11 close to the shell cap 12, and the hydrogen outlet valve 42 is located at the bottom of the shell body 11 away from the shell cap 12.
