[0002] Hydrogen gas sources are often used as hydrogen flame ionization detectors (FID) and flame photometric detectors (FPD). There are two common ways to store hydrogen: bottled high-pressure compressed hydrogen and metal hydride hydrogen storage. Metal hydride hydrogen storage modules have good safety, no explosion hazard, can be used repeatedly, and have the function of improving the purity of hydrogen. In addition, metal hydride hydrogen storage bottles have some significant advantages. First, its hydrogen storage density is high and it can store a large amount of hydrogen. Second, metal hydrides are usually solid at room temperature, so they are relatively convenient to store and transport.

When the ambient temperature is low or the heat dissipation performance of the hydrogen storage bottle is good, natural heat dissipation may be sufficient to meet the cooling needs, but it is not suitable for high temperature environments, or by generating airflow through fans to accelerate the flow of air on the surface of the hydrogen storage bottle, thereby improving the heat dissipation efficiency, that is, installing fans outside the hydrogen storage bottle can speed up the heat dissipation speed of the hydrogen storage bottle during the filling process.

[0031] like Figure 1-8 A metal hydride hydrogen storage bottle charging and cooling device shown includes an exchange type rapid cooling gas cylinder 1, the exchange type rapid cooling gas cylinder 1 includes a hydrogen storage bottle body 2, a seismic base 3, a hollow frame 4, a wrapping sleeve 5, a serrated sealing rubber pad 6, a water inlet assembly 7 and a cooling assembly 8, the hydrogen storage bottle body 2 is sleeved on the inner side of the wrapping sleeve 5, the serrated sealing rubber pad 6 is adhesively connected to the inner side of the wrapping sleeve 5, the top of the seismic base 3 is fixedly connected to the bottom surface of the hollow frame 4, the bottom of the wrapping sleeve 5 is fixedly connected to the top surface of the hollow frame 4, the hollow frame 4 is sleeved on the outside of the hydrogen storage bottle body 2, the water inlet assembly 7 is installed on one side of the bottom of the hollow frame 4, the cooling assembly 8 is installed on the inner side of the top of the hollow frame 4, and the bottom of the wrapping sleeve 5 is also installed with a surrounding heat dissipation assembly 9;

[0032] The hydrogen storage bottle body 2 is used for storing and transporting metal hydrides, the anti-vibration base 3 is used for supporting the hydrogen storage bottle body 2 and fully absorbing shock, the hollow frame 4 is mounted on the outside of the hydrogen storage bottle body 2 for fully insulating and protecting the hydrogen storage bottle body 2, the wrapping sleeve 5 is used to support the surrounding heat dissipation component 9, the surrounding heat dissipation component 9 is used to disrupt the directional flow of the solution inside the hollow frame 4 and accelerate heat dissipation, the serrated sealing pad 6 is used to closely contact the hydrogen storage bottle body 2 and prevent dust from entering the inside, the water inlet component 7 is used to pass water into the hollow frame 4, and the cooling component 8 adopts a heat exchange method and controls the overall temperature of the hydrogen storage bottle body 2.

[0033] This product is provided with a plurality of cooling tubes 19 in a circular array inside the hollow frame 4. When the hydrogen storage bottle 2 is overheated, a certain amount of refrigerant can be injected into the cooling tubes 19 so that the cooling tubes 19 surround the inside of the hydrogen storage bottle 2 and complete rapid heat exchange and cooling in a liquid environment. This product can control the position of the sliding inner cover 13 through a small motor 15 to fully expose the water delivery notch 28, thereby controlling the entry and emptying of the internal water flow, and providing a suitable environment for cooling the hydrogen storage bottle 2.

[0034] The water inlet assembly 7 includes a straight-connecting pipe 10, a two-way valve 11, a water pipe 12, a sliding inner cover 13, a connecting shaft 14 and a small motor 15. The outer side of the straight-connecting pipe 10 is clamped with the two-way valve 11, and the two sides of the water pipe 12 are respectively clamped with the inner side of the straight-connecting pipe 10 and the bottom surface of the hydrogen storage bottle 2.

The small motor 15 is installed inside one side of the water pipe 12 and is used to connect the connecting shaft 14.

[0035] When water is intake, the two-way valve 11 can be opened to the water intake position, and the direct pipe can be connected to the water intake pipe. The water flows from the direct pipe 10 into the water delivery pipe 12. Then, the small motor 15 is started to drive the sliding inner cover 13 to rotate through the connecting shaft 14 until the aperture of the water delivery groove 28 of the sliding inner cover 13 coincides with that of the water delivery groove 28 of the water delivery pipe 12, so that the water can flow from the water delivery pipe 12 into the interior of the hollow frame 4. As the water level gradually deepens, the water level can be controlled within 2 / 3 of the height of the hydrogen storage bottle, thereby providing a stable heat exchange environment.

[0037] The refrigerant pipeline is connected to the feed pipe 16, and then the one-way valve 17 is opened to allow the refrigerant to flow from the feed pipe 16 into the circular material tray 18, and then flow from the bottom of the circular material tray 18 under the action of gravity into the cooling tubes 19 and fill them, so that the water inside the hollow frame 4 fully contacts with the cooling tubes 19 after absorbing heat and completes heat exchange, thereby reducing the water temperature and indirectly cooling the hydrogen storage bottle 2 quickly.

[0038] The surround heat dissipation assembly 9 includes an annular frame 20, a movable bracket 21, a connecting plate 22, a heat pipe 23, a stepper motor 24, a drive shaft 25 and a locking gear 26. The annular frame 20 is fixedly connected to the inner side of the bottom of the wrapping sleeve 5, the movable bracket 21 is slidably engaged with the inner side of the annular frame 20, the connecting plate 22 is installed at the bottom of the movable bracket 21, the heat pipe 23 is threadedly connected to the bottom of the connecting plate 22, the stepper motor 24 is installed on the outer side of the movable bracket 21, the drive shaft 25 passes through one side of the movable bracket 21 and is fixedly connected to the motor shaft of the stepper motor 24, and the locking gear 26 is sleeved on the outside of the drive shaft 25.

[0039] An inner rack 27 meshing with the outer teeth of the locking gear 26 is also formed on the inner side of the annular frame 20 .

[0040] Water delivery notches 28 of equal size are also provided on opposite sides of the water delivery pipe 12 and the sliding inner cover 13 .

[0041] During the cooling process, the stepper motor 24 on the outside of the movable bracket 21 can be started synchronously, and the locking gear 26 can be driven to rotate through the driving shaft 25. Since the locking gear 26 and the embedded rack 27 are meshed with each other, under the gear transmission, the movable bracket 21 can drive the connecting plate 22 and the heat pipe 23 at the bottom to perform circular motion along the surface of the annular frame 20. The heat pipe 23 stirs the water inside to disrupt the static effect, so that the evaporation section at the bottom of the heat pipe 23 can fully contact the water, thereby accelerating the heat dissipation rate of the hydrogen storage bottle 2.

[0042] The interior of the seismic-resistant base 3 is also provided with a blind hole 29, a support plate 30, a galvanized steel cover 31, a compression spring 32 and an air chamber damping rod 33. The blind hole 29 is opened on the inner side of the middle part of the seismic-resistant base 3. The top of the support plate 30 is in contact with the bottom surface of the hydrogen storage bottle body 2. The top of the galvanized steel cover 31 is in contact with the bottom surface of the support plate 30. Both sides of the compression spring 32 are fixedly connected to the opposite sides of the galvanized steel cover 31.

[0043] A limiting groove 34 is further provided on the inner side of the movable bracket 21 .

[0044] The thermal insulation coating 35 coated on the surface of the hollow frame 4 can provide sufficient insulation. During transportation, when the hydrogen storage bottle body 2 shakes, the compression spring 32 on the inside is fully compressed and deformed, so that the air chamber damping rod 33 can absorb and disperse the impact energy from the equipment, thereby reducing the shaking amplitude and improving the stability of the seismic base 3 and the hydrogen storage bottle body 2.

[0045] Working principle: When water is entering, the two-way valve 11 can be opened to the water inlet level, and the direct pipe can be connected to the water inlet pipe. The water flows from the direct pipe 10 into the water delivery pipe 12. Then the small motor 15 is started to drive the sliding inner cover 13 to rotate through the connecting shaft 14 until the aperture of the water delivery slot 28 of the sliding inner cover 13 coincides with the aperture of the water delivery slot 28 of the water delivery pipe 12, so that the water can flow from the water delivery pipe 12 into the interior of the hollow frame 4. As the water level gradually deepens, the water level can be controlled at the hydrogen storage bottle body. 2 is within 2 / 3 of the height, thereby providing a stable heat exchange environment; the refrigerant pipeline is connected to the feed pipe 16, and then the one-way valve 17 is opened to allow the refrigerant to flow from the feed pipe 16 into the circular material tray 18, and then under the action of gravity, it flows from the bottom of the circular material tray 18 into the interior of each cooling pipe 19 and fills it, so that the water inside the hollow frame 4 is fully in contact with the cooling pipe 19 after absorbing heat and completes heat exchange, thereby reducing the water temperature, and then indirectly cooling the hydrogen storage bottle 2 quickly. During the cooling process, the stepper motor 24 on the outside of the movable bracket 21 can be started synchronously, and the locking gear 26 can be driven to rotate through the driving shaft 25. Since the locking gear 26 and the embedded rack 27 are meshed with each other, under the gear transmission, the movable bracket 21 can drive the connecting plate 22 and the heat pipe 23 at the bottom to perform circular motion along the surface of the annular frame 20. The heat pipe 23 stirs the water inside to disrupt the static effect, so that the evaporation section at the bottom of the heat pipe 23 can fully contact the water, thereby accelerating the heat dissipation rate of the hydrogen storage bottle 2.
