[0002] With rising living standards, more and more young people enjoy outdoor activities like camping and picnics. Therefore, heating food and cooling beverages have become a major concern. While existing outdoor heating devices are relatively mature, outdoor cooling devices are more limited. While some existing outdoor cooling devices exist, such as refrigerators or cooler cylinders, these require a portable power bank, resulting in a complex and bulky design that makes them unsuitable for outdoor use.

[0003] Solid-state hydrogen storage devices, using built-in metal hydrides as hydrogen storage carriers, have gradually been widely used in various energy devices, from automotive fuel cells to home heating systems. Due to their high safety, strong adaptability, and light weight, hydrogen storage devices are also suitable for applications such as outdoor picnics, outdoor travel, and mountain climbing. Metal hydrides can reversibly absorb, store, and release hydrogen under certain temperatures and pressures. The metal hydride exhibits an endothermic reaction during the hydrogen release process. This reaction characteristic allows the metal hydride to have a certain cooling effect during the hydrogen release process, forming a cold source. Therefore, how to rationally use hydrogen storage devices to design an outdoor picnic device that combines heating and cooling has become an urgent problem that technicians in this field need to solve.

[0034] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without one or more of these details. In other instances, certain technical features well known in the art are not described to avoid confusion with the present invention.

[0035] See attached Figures 1 to 7 A hydrogen combustion furnace system based on solid-state hydrogen storage includes: a solid-state hydrogen storage device 100, a cooling device and a hydrogen combustion device 200.

[0036] The solid-state hydrogen storage device 100 includes a bottle body, a solid-state hydrogen storage material built into the bottle body, and a valve body 110 arranged on the bottle body or connected to the hydrogen outlet of the bottle body. The refrigeration cavity 300 covers or wraps around the circumference and / or bottom of the solid-state hydrogen storage device 100, and is provided with a liquid inlet 310 and / or a liquid outlet 320 on the refrigeration cavity 300. Specifically, the liquid inlet 310 is located above the refrigeration cavity 300 and is provided with a detachable funnel; the liquid outlet 320 is located below the refrigeration cavity 300 and is provided with a valve and / or a plug. In addition, an insulation cover 400 is provided on the outside of the refrigeration cavity 300. The insulation cover 400 covers at least the circumference and bottom of the refrigeration cavity 300. The insulation cover 400 is made of a flexible, loose, porous fiber material or plastic material and has a relatively excellent thermal insulation effect.

[0037] The minimum refrigeration temperature of the solid-state hydrogen storage device 100 can reach 4°C. Due to the limited refrigeration capacity of the solid-state hydrogen storage device 100, the applicant has designed the structure of the cooling device, especially the structure of the refrigeration cavity 300, to make fuller use of the cold source generated by the solid-state hydrogen storage device 100. The structure of the refrigeration cavity 300 can be expressed in various ways.

[0038] Method 1, see attached Figure 2 The refrigeration cavity 300 is a closed cavity made of metal, which has relatively high thermal conductivity. The refrigeration cavity 300 and the solid-state hydrogen storage device 100 can be detachably connected through snaps, threads, mortise and tenon joints, etc., improving the structural stability of the refrigeration device and facilitating installation and removal. Furthermore, the thickness of the closed cavity is minimized to increase the contact area between the refrigeration cavity 300 and the solid-state hydrogen storage device 100. However, the volume of the refrigeration cavity 300 must be maintained between 550 and 2000 ml, sufficient to accommodate at least one bottled beverage.

[0039] Method 2, see attached Figure 3The refrigeration cavity 300 is a pipe 330 spirally wound along the bottle body. Specifically, the refrigeration cavity 300 can be a spiral structure made of a metal pipe 330. Since the metal pipe 330 has relatively high structural rigidity, it is convenient to install and remove the solid-state hydrogen storage device 100. Of course, the refrigeration cavity 300 can also include a spiral bracket and a flexible pipe 330. The spiral bracket is a cylindrical hollow bracket, the inner side of which is fixed to the circumference of the hydrogen storage device, and a spiral slot is provided on the outside of the hollow bracket for installing the flexible pipe 330, which can also facilitate the user's installation and removal.

[0040] Method 3, see attached Figure 4 The refrigeration cavity 300 includes two interconnected first cavities 340 and second cavities 350. The first cavities 340 and second cavities 350 are respectively recessed inward to form a first placement groove 360 ​​and a second placement groove 370. The first placement groove 360 ​​covers the circumference and bottom of the solid-state hydrogen storage device 100, and the second placement groove 370 is suitable for placing food to be cooled. The refrigeration cavity 300 and the solid-state hydrogen storage device 100 can be connected in a detachable manner such as a snap, a thread, a mortise and tenon structure, thereby improving the structural stability of the refrigeration device and facilitating the disassembly of the refrigeration device. By introducing a heat-conducting medium into the refrigeration cavity 300, the heat-conducting medium can be a liquid such as a beverage product or outdoor clean water, which is used to conduct heat and achieve the cooling effect of the entire refrigeration device. In addition, in order to improve the thermal insulation performance of the second placement groove 370, the second placement groove 370 is also provided with a cover 380 made of a heat-insulating material.

[0041] Method 4, see attached Figure 5The refrigeration cavity 300 includes two interconnected first cavities 340 and second cavities 350. The first cavity 340 and the second cavity 350 are respectively recessed inward to form a first placement groove 360 ​​and a second placement groove 370. The first placement groove 360 ​​and the second placement groove 370 form a concentric circle structure. The first placement groove 360 ​​is located inside the second placement groove 370. Such a setting can further reduce the heat loss of the refrigeration device and improve the energy utilization rate of the entire hydrogen generator. The first placement groove 360 ​​is covered on the circumference and bottom of the solid-state hydrogen storage device 100, and the second placement groove 370 is suitable for placing food to be cooled. The refrigeration cavity 300 and the solid-state hydrogen storage device 100 can be connected in a detachable manner such as a snap, a thread, a mortise and tenon structure, thereby improving the structural stability of the refrigeration device and facilitating the disassembly of the refrigeration device. By introducing a heat-conducting medium into the refrigeration cavity 300, the heat-conducting medium can be a liquid such as a beverage product or outdoor clean water, which is used to conduct heat and achieve the cooling effect of the entire refrigeration device. In addition, in order to improve the heat preservation performance of the second placement groove 370, the second placement groove 370 is further provided with a cover body 380 made of heat insulation material.

[0042] In a further embodiment, an air outlet 390 is provided at the upper portion of the refrigeration cavity 300, away from the liquid inlet 310. In this embodiment, the liquid inlet 310 is provided at the upper portion of the first cavity 340, and the air outlet 390 is provided at the upper portion of the second cavity 350. Furthermore, a removable sealing plug is provided on the air outlet 390 to ensure the airtightness of the entire refrigeration cavity 300. When the heat transfer medium is much smaller than the minimum volume of the refrigeration cavity 300, the sealing plug can be closed and then the heat transfer medium can be added. This allows more of the heat transfer medium to be located within the first cavity 340, that is, around the circumference and bottom of the solid-state hydrogen storage device 100, thereby improving the thermal conductivity of the entire refrigeration device.

[0043] In a further embodiment, for the solutions of the third and fourth methods, since the flow of the heat-conducting liquid in the first cavity 340 and the second cavity 350 is relatively small, in order to improve the fluidity of the heat-conducting liquid, a stirring device can be set in the first cavity 340 and the second cavity 350. However, considering various factors such as power supply, hydrogen supply stability and thermal insulation performance, see the attached Figure 6The stirring device includes a piston 321 sealed at the liquid outlet 320, a mounting cap 322 detachably mounted on the liquid outlet 320, and a push rod 323 extending through the mounting cap 322 and connected to the piston 321, adapted to drive the piston 321 to move left and right along the liquid outlet 320. By moving the piston 321 and coordinating the air intake and exhaust of the sealing plug, the fluidity of the heat-conducting liquid within the first cavity 340 and the second cavity 350 is improved, thereby enhancing the cooling effect of the entire refrigeration device.

[0044] The hydrogen combustion device 200 is connected to the hydrogen outlet of the solid-state hydrogen storage device 100 via a hydrogen supply line 120, and at least one control valve 210 is provided on the hydrogen supply line 120. The hydrogen combustion device 200 can be a gas appliance of the type of a gas stove, a gas barbecue grill, etc. Of course, for those skilled in the art, the hydrogen combustion device 200 is not limited to gas appliances, and can also be other energy conversion equipment, such as a hydrogen fuel cell stack. A quick-install male plug or a quick-install female plug is installed at the hydrogen outlet of the solid-state hydrogen storage device 100, and a quick-install female plug or a quick-install male plug that matches the quick-install male plug or the quick-install female plug is installed at one end of the hydrogen supply line 120. This facilitates the disassembly and assembly of the hydrogen combustion device 200 and the solid-state hydrogen storage device 100, making it easy for users to carry.

[0045] In a further embodiment, the control valve 210 is disposed within the hydrogen combustion device 200 and comprises an electrically controlled valve and a manually adjustable valve. The electrically controlled valve is disposed on the hydrogen supply line 120 and is preferably a mechanically controlled valve that automatically shuts off the hydrogen supply line 120 by detecting temperature changes in the hydrogen supply line 120. The manually adjustable valve is disposed on the hydrogen supply line 120 and manually adjusts the opening of the hydrogen supply line 120.

[0046] In a further embodiment, the solid-state hydrogen storage device 100 is mounted on a fixing bracket 500 so that the solid-state hydrogen storage device 100 maintains a predetermined tilt angle. Figure 7The fixing bracket 500 includes a base plate 510, two support rods 520 with adjustable angles arranged on one side of the base plate 510, a clamp 530 arranged on the two support rods 520 for fixing one end of the solid-state hydrogen storage device 100, and a lifting pad 540 arranged on the other side of the base plate 510. The solid-state hydrogen storage device 100 is fixed by a triangular bracket. Firstly, since existing hydrogen fuel application systems generally have complex pressure reduction circuits to stabilize the hydrogen pressure in the hydrogen supply circuit, but since the gas furnace system in this embodiment is an outdoor device, it is necessary to consider the ease of installation and the portability of the device. By fixing the solid-state hydrogen storage device 100, the impact of the shaking of the solid-state hydrogen storage device 100 on the pressure stability of the hydrogen supply circuit is reduced; secondly, the inclined setting can increase the degree of expansion of the solid-state hydrogen storage material in the solid-state hydrogen storage device 100, and at the same time, prevent the solid-state hydrogen storage material from flooding the hydrogen outlet of the solid-state hydrogen storage device 100, thereby improving the hydrogen output efficiency and hydrogen output stability of the solid-state hydrogen storage device 100. Thirdly, the bottom of the solid-state hydrogen storage device 100 is suspended in the air by fixing the bracket 500 , so that the user can operate the stirring device without shaking the solid-state hydrogen storage device 100 to achieve the flow of the heat transfer medium in the refrigeration cavity 300 .

[0047] In order to facilitate understanding of the technical solution of the hydrogen combustion furnace system based on solid hydrogen storage, its working principle is briefly described: during the construction process, the solid hydrogen storage device 100 is fixedly installed in the refrigeration cavity 300, and then the solid hydrogen storage device 100 and the refrigeration cavity 300 are installed on the fixed bracket 500, and the angle is adjusted to the preset angle of the solid hydrogen storage device 100 of this model, and then the solid hydrogen storage device 100 and the hydrogen combustion device 200 are connected by the quick-release female plug and the quick-release male plug to form a hydrogen combustion furnace system based on solid hydrogen storage. During use, the beverage product is poured into the refrigeration cavity 300 by placing a detachable funnel in the liquid inlet 310, and then the opening of the manual regulating valve is adjusted to continuously supply hydrogen to the hydrogen consumption equipment; at the same time, the solid hydrogen storage device 100 refrigerates the beverage product in the refrigeration cavity 300 during the release of hydrogen, and the entire hydrogen combustion furnace system based on solid hydrogen storage has a simple structure, is easy to install, is convenient for users to carry, and is suitable for outdoor use.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present invention will not further describe various possible combinations.
