Description

Technical Field

[0001] The utility model relates to the technical field of solid-state hydrogen storage, in particular to a device for heat preservation and cooling a magnesium alloy solid-state hydrogen storage material test container. Background Art

[0002] Magnesium-based hydrogen storage materials are promising solid hydrogen storage materials. They have a high hydrogen storage capacity (7.6 wt.%), are widely available, are non-toxic, low-cost, and safe, making them suitable for large-scale hydrogen storage and transportation. The principle of magnesium alloy hydrogen storage is that under certain temperature and hydrogen pressure conditions, magnesium alloys undergo a reversible hydrogen absorption and dehydrogenation reaction with hydrogen, enabling hydrogen storage and release.

[0003] Chinese patent application number CN2020113762812 discloses a magnesium-based solid-state hydrogen storage material performance testing system, which is used to test the properties and characteristics of magnesium alloy solid-state hydrogen storage materials. However, since the hydrogen absorption and dehydrogenation reactions require a large amount of energy, the dissipated heat cannot be well recovered and utilized. In addition, the cooling system of the entire system mainly relies on heat exchange with the air in the environment for cooling, and the speed is relatively slow, which affects the normal test time and energy consumption. Utility Model Content

[0004] The purpose of the utility model is to address the above-mentioned deficiencies in the prior art and to provide a device for heat preservation and cooling a magnesium alloy solid hydrogen storage material test container.

[0005] The utility model discloses a device for insulating and cooling a magnesium alloy solid-state hydrogen storage material test container. The magnesium alloy solid-state hydrogen storage material test container is filled with magnesium alloy hydrogen storage material. The device comprises a solid-state hydrogen storage software system, a temperature detection system and a plurality of semiconductor refrigeration sheets. The temperature detection system is used to detect the internal temperature of the magnesium alloy solid-state hydrogen storage material test container. All the semiconductor refrigeration sheets are attached to the surface of the magnesium alloy solid-state hydrogen storage material test container at intervals. The plurality of semiconductor refrigeration sheets are respectively connected in series to form several series circuits. The series circuits are electrically connected in parallel with a power supply system. The solid-state hydrogen storage software system is electrically connected to the temperature detection system and the power supply system.

[0006] Furthermore, the temperature detection system includes a thermocouple, which is inserted into the magnesium alloy solid hydrogen storage material test container along its axial direction for detecting its internal temperature; the thermocouple is electrically connected to the solid hydrogen storage software system.

[0007] Furthermore, it also includes an electric energy storage device, which is detachably electrically connected to a plurality of semiconductor refrigeration plates via cables, and the electric energy storage device is electrically connected to the power supply system via an inverter.

[0008] Furthermore, the electric energy storage device includes a charge and discharge controller and a battery, the semiconductor refrigeration plate is electrically connected to the charge and discharge controller, the charge and discharge controller is electrically connected to the battery, and the charge and discharge controller is electrically connected to the power supply system through an inverter.

[0009] Furthermore, it also includes a solar power storage system, which is electrically connected to the charge and discharge controller.

[0010] When testing the hydrogen absorption performance of the magnesium alloy solid hydrogen storage material in the magnesium alloy solid hydrogen storage material test container, the solid hydrogen storage software system detects through the temperature detection system that the temperature of the magnesium alloy solid hydrogen storage material is less than 160°C and the heating rate is less than the preset value. At this time, the magnesium alloy solid hydrogen storage material test container needs to be insulated. The solid hydrogen storage software system controls the power supply system to supply power to the group of semiconductor refrigeration plates. After receiving the current, the semiconductor produces Peltier effect and Thomson effect, causing the surface of the container to absorb heat, and the end close to the container will release heat, providing the container with insulation function. When When the solid-state hydrogen storage software system detects through the temperature detection system that the temperature of the magnesium alloy solid-state hydrogen storage material exceeds 160°C and the heating rate is greater than the preset value, the magnesium alloy solid-state hydrogen storage material test container needs to be quickly cooled down. The solid-state hydrogen storage software system controls the power supply system to supply power to the group of semiconductor refrigerators, and changes the direction of the current, swapping the hot and cold ends of the semiconductor refrigerators. After receiving the current, the semiconductor refrigerators produce Peltier effect and Thomson effect, causing the semiconductor refrigerators close to the container to absorb heat, and the outer end of the container will release heat, quickly dissipating the heat from the container.

[0011] When testing the hydrogen desorption performance of the magnesium alloy solid hydrogen storage material in the magnesium alloy solid hydrogen storage material test container, hydrogen desorption will absorb heat, and the temperature range is between 260℃ and 370℃, so continuous heating is required. At this time, if there are no insulation measures, the temperature will dissipate quickly and consume more energy. The use of semiconductor refrigeration plates can prevent the dissipated energy to a certain extent, so that the temperature can rise faster and reach the hydrogen desorption temperature, and the material can continue to desorb hydrogen. Therefore, the magnesium alloy solid hydrogen storage material test container needs to be insulated throughout the process. At this time, the solid-state hydrogen storage software system controls the power supply system to power the grouped semiconductor refrigeration plates. After receiving the current, the semiconductor produces Peltier effect and Thomson effect, causing heat absorption on the surface of the container, and heat release near the end of the container to keep the container warm.

[0012] The temperature difference detected by the temperature detection system received by the solid-state hydrogen storage software system over time can be used to accurately control the output current of the power supply system using the PID temperature self-tuning function of the solid-state hydrogen storage software system, thereby achieving accurate temperature preservation or cooling function of the material in the container.

[0013] The utility model provides a device for insulating and cooling a magnesium alloy solid-state hydrogen storage material test container, which operates fully automatically and does not add any additional burden to the device itself. When insulation is required, the semiconductor refrigeration plate can prevent the dissipated energy to a certain extent, so that the temperature can be raised relatively quickly. When cooling is required, the rapid cooling function of the semiconductor refrigeration plate is used, which is faster and more efficient than ordinary cooling, thereby improving the heat exchange rate of the cooling system of the entire system and saving the test time. Moreover, after the test is completed, for safety reasons, the temperature of the entire system including the temperature of the material needs to be lowered to room temperature. If the rapid cooling function of the semiconductor refrigeration plate can be used to quickly cool a magnesium alloy solid-state hydrogen storage material test container to room temperature, the rapid cooling function is faster and more efficient than ordinary cooling.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, the utility model is a device for insulating and cooling a magnesium alloy solid-state hydrogen storage material test container, the magnesium alloy solid-state hydrogen storage material test container is filled with magnesium alloy hydrogen storage material, including a solid-state hydrogen storage software system 1, a temperature detection system 2 and a plurality of semiconductor refrigeration plates 3, the temperature detection system 2 is used to detect the internal temperature of the magnesium alloy solid-state hydrogen storage material test container 4, all semiconductor refrigeration plates 3 are attached to the surface of the magnesium alloy solid-state hydrogen storage material test container 4 at intervals, and the plurality of semiconductor refrigeration plates 3 are respectively connected in series to form several series circuits, the series circuits are electrically connected in parallel with the power supply system 5, and the solid-state hydrogen storage software system 1 is electrically connected to the temperature detection system 2 and the power supply system 5.

[0018] When the hydrogen absorption performance of the magnesium alloy solid hydrogen storage material in the magnesium alloy solid hydrogen storage material test container 4 is tested, the solid hydrogen storage software system 1 detects through the temperature detection system 2 that the temperature of the magnesium alloy solid hydrogen storage material is less than 160°C and the heating rate is less than the preset value, then the magnesium alloy solid hydrogen storage material test container 4 needs to be insulated. The solid hydrogen storage software system 1 controls the power supply system 5 to supply power to the group of semiconductor refrigeration plates 3. After receiving the current, the semiconductor generates the Peltier effect and the Thomson effect, causing the surface of the container to absorb heat, and the end close to the container will release heat, which provides the container with a heat preservation function. When the solid hydrogen storage software system 1 controls the power supply system 5 to supply power to the group of semiconductor refrigeration plates 3, the semiconductor generates the Peltier effect and the Thomson effect, causing the surface of the container to absorb heat, and the end close to the container will release heat, which provides the container with a heat preservation function. When the solid-state hydrogen storage software system 1 detects through the temperature detection system 2 that the temperature of the magnesium alloy solid-state hydrogen storage material exceeds 160°C and the heating rate is greater than a preset value, the magnesium alloy solid-state hydrogen storage material test container 4 needs to be quickly cooled down. The solid-state hydrogen storage software system 1 controls the power supply system 5 to supply power to the grouped semiconductor refrigeration plates 3, and changes the direction of the energized current, swapping the hot and cold ends of the semiconductor refrigeration plates 3. After receiving the current, the semiconductor refrigeration plates 3 produce Peltier effect and Thomson effect, causing the semiconductor refrigeration plates 3 to absorb heat when close to the container, and the outer end of the container will release heat, thereby quickly dissipating the heat from the container.

[0019] When the hydrogen desorption performance of the magnesium alloy solid hydrogen storage material in the magnesium alloy solid hydrogen storage material test container 4 is tested, hydrogen desorption will absorb heat, and the temperature range is between 260℃ and 370℃, so continuous heating is required. At this time, if there are no insulation measures, the temperature will dissipate quickly and consume more energy. The use of semiconductor refrigeration plates 3 can prevent the dissipated energy to a certain extent, so that the temperature can rise faster and reach the hydrogen desorption temperature, and the material can continue to desorb hydrogen. Therefore, the magnesium alloy solid hydrogen storage material test container 4 needs to be insulated throughout the process. At this time, the solid-state hydrogen storage software system 1 controls the power supply system 5 to supply power to the grouped semiconductor refrigeration plates 3. After receiving the current, the semiconductor generates Peltier effect and Thomson effect, causing heat absorption on the surface of the container, and heat release near the end of the container to keep the container warm.

[0020] The temperature difference detected by the temperature detection system received by the solid-state hydrogen storage software system 1 over time can be used to accurately control the output current of the power supply system 5 using the PID temperature self-tuning function (existing technology) of the solid-state hydrogen storage software system 1, thereby achieving accurate temperature preservation or cooling function of the material in the container.

[0021] The utility model provides a device for insulating and cooling a magnesium alloy solid-state hydrogen storage material test container, which operates fully automatically and does not add any additional burden to the device itself. When insulation is required, the semiconductor refrigeration plate 3 can prevent the dissipated energy to a certain extent, so that the temperature can be raised relatively quickly. If the rapid cooling function of the semiconductor refrigeration plate 3 is used, it is faster than ordinary cooling and more efficient, thereby improving the heat exchange rate of the cooling system of the entire system and saving the test time. Moreover, after the test is completed, for safety reasons, the temperature of the entire system including the temperature of the material needs to be lowered to room temperature. If the rapid cooling function of the semiconductor refrigeration plate 3 is used to quickly cool a magnesium alloy solid-state hydrogen storage material test container 4 to room temperature, it is faster than ordinary cooling and more efficient.

[0022] The temperature detection system 2 can have various structures. The temperature detection system 2 can include a thermocouple 21 inserted axially within the magnesium alloy solid hydrogen storage material test container 4 for detecting the internal temperature. The thermocouple 21 is electrically connected to the solid hydrogen storage software system 1. The internal temperature of the magnesium alloy solid hydrogen storage material test container 4 is detected by the thermocouple 21, and the temperature difference of the thermocouple inserted into the container over time is received by the solid hydrogen storage software system. This facilitates both installation and accurate detection.

[0023] After the test is completed, for safety reasons, the temperature of the entire system including the material temperature needs to be lowered to room temperature. The rapid cooling function of the semiconductor refrigeration plate 3 can quickly cool a magnesium alloy solid hydrogen storage material test container 4 to room temperature, which is faster and more efficient than ordinary cooling. However, after the test is completed, the heat can also be recovered through the semiconductor refrigeration plate 3. Therefore, in an operative method, an energy storage device 6 can also be included. The energy storage device 6 is detachably electrically connected to multiple semiconductor refrigeration plates 3 through cables, and the energy storage device 6 is electrically connected to the power supply system 5 through an inverter 8. Heat will escape from the magnesium alloy solid hydrogen storage material test container 4, and a large temperature difference will be formed between the surface of the magnesium alloy solid hydrogen storage material test container 4 and the air. By using the Seebeck effect of the semiconductor refrigeration plate 3, all cables of the semiconductor refrigeration plate 3 are connected in parallel to generate a very high DC voltage, which is charged into the energy storage device 6. The energy storage device 6 is electrically connected to the power supply system 5 through the inverter 8. The energy storage device 6 releases DC power to the inverter 8, and the inverter 8 converts the DC voltage into AC voltage and incorporates it into the power supply system 5 of the magnesium alloy solid hydrogen storage container, thereby achieving the effect of saving electricity.

[0024] The energy storage device 6 can have various structures, which are not limited here. In this embodiment, the energy storage device 6 can include a charge and discharge controller 61 and a battery 62. The semiconductor cooling plate 3 is electrically connected to the charge and discharge controller 61, which is electrically connected to the battery 62. The charge and discharge controller 61 is electrically connected to the power supply system 5 via the inverter 8. After all the cables of the semiconductor cooling plate 3 are connected in parallel, a very high DC voltage is generated. This voltage is converted to a standard voltage by the charge and discharge controller 61 and charged into the battery 62. To use the battery power, it needs to pass through the discharge function of the charge and discharge controller before being connected to the inverter 8.

[0025] It can also include a solar energy storage system 7, which is electrically connected to the charge and discharge controller 61. By connecting the solar energy storage system 7 in the prior art to the charge and discharge controller 61 at the same time, the subsequent electricity can undergo the same processing, making the energy saving effect more significant.
