1 TARIFF ENERGY-SAVING HYDROGEN TANKS FOR VEHICLES Technical Area The invention relates to a heating and / or cooling effect during the release of stored hydrogen. It is a unit that provides heat gain by generating heat. 5 The invention is particularly useful in all vehicles that use hydrogen, including land and spacecraft, for storing hydrogen. by controlling pressure changes during the expansion of hydrogen, the released a system that converts energy into heat gain for other systems by creating a heating or cooling effect It is a unit. State of the Art 10 Today, the energy of hydrogen stored in vehicles is obtained during the use of hydrogen. There is no application that uses it. In current systems, hydrogen is produced using a number of methods. (For example: electrolysis) (result) Then this hydrogen is pressurized with the help of a compressor. It is stored. Sometimes, depending on the storage rate, local 15 at hydrogen transfer centers. To prevent overheating, additional cooling units are used alongside these units. This stored hydrogen is pressurized to obtain an energy-dense structure. It is held in a structure. Then this pressurized hydrogen is used in a system. when it is desired to use (for example: fuel cell) also a pressure reduction unit By passing it through, the pressure is reduced in a controlled manner and then 20 is converted into electrical energy in the unit. It is transformed. The main problem with these applications is their high cost. Also, hydrogen... A lot of energy is consumed during its production and storage. Fuel cell... There is no recovery mechanism in the production and transmission of up to that amount of hydrogen. It was not established or designed. 25 In the relevant US patent application, US2010193070A1, regarding pressurized gases... The filling of tanks was mentioned, and a method for doing so was described. Essentially, it describes the process for filling high-pressure hydrogen tanks. 2 However, there is no information regarding heat gain during the pressure reduction process after filling. It is not available. The patent application WO2005100894A1, related to this topic, describes a multi-pass heat exchanger. It has been mentioned that hydrogen gas and liquid are used for heat exchange here. Their costs... These are the factors that increase it. It is not providing the desired benefit. 5 In conclusion, due to the negative aspects described above and the current solutions, the subject matter... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been observed. Purpose of the Invention The invention represents a new breakthrough in this field, unlike the structures used in the current technology. The aim is to create a structure with different technical specifications that bring these elements together. The purpose of the invention is to store hydrogen at high pressure in vehicles and to reduce its pressure as needed. the energy released during the liquefaction process by reducing it to the required subsystems It is used to provide heating or cooling. Another aim of the invention is to recover the 15% that is considered lost during the hydrogen liquefaction process. or the recovery of overlooked energy back into the system. To fulfill the purposes stated above, the invention incorporates a solenoid valve, pressure and temperature control system. sensor assembly, hydrogen inlet, liquid inlet, heat exchange unit, liquid outlet and hydrogen outlet It includes. Explanation of Figures 20 Figure 1 shows the appearance of the energy-recovering hydrogen tank, which is the subject of this invention.

The invention in question involves a pressurized hydrogen tank and the use of this hydrogen to generate energy. It is a hydrogen-liquid heat exchange unit that will be inserted between the fuel cell that will produce (5). A solenoid valve (1) can be used to pump high pressure from high pressure tanks. The heat exchange unit (5) is fed by the hydrogen inlet (3) pipe. Meanwhile, the heat exchange High pressure hydrogen inlet (3) entering unit (5) pressure and temperature sensor group (2) It is checked that the pressurized hydrogen is continuously delivered under suitable conditions. It is monitored. During this time, the liquid, heat that will be continuously provided to the unit (5) in the system. It is fed for transfer (4). 15 Pressurized hydrogen entering the heat exchange unit (5) is placed on the hydrogen inlet (3). It continues in its own channel and proceeds toward the low-pressure hydrogen outlet (7). Heat exchange of hydrogen at reduced pressure, needed by other components. This is the line from which unit (5) exits. When leaving the heat exchange unit (5), the hydrogen reaches a dangerous temperature and pressure of 20 real-time pressure and temperature monitoring to ensure they do not exceed certain levels. Measurements are made with the control sensor group (2). The sensor group measures the pressure change and by controlling temperature variations, hydrogen can be prevented from reaching dangerous temperature and pressure levels. prevents leakage. Liquid inlet (4) for heat transfer to the heat exchange unit (5) The liquid coming from above is heated by the hydrogen entering from the high-pressure hydrogen inlet (3) 25 Heat transfer takes place inside the exchange unit (5) and the heat transfer fluid exits from the fluid outlet. (6) leaves the unit (5) with a changed temperature. The liquid coming from the unit (5) which has a heat input requirement in the system to which it is connected, heat transfer The liquid input will come through (4). Here the decision-making mechanism is the solenoid valve (1). The pressure of the incoming and outgoing hydrogen and 30 data from the pressure and temperature sensor group measuring its temperature (2) and heat exchanger 4 The temperature targets of the liquid are at the liquid inlet (4) and liquid outlet (6) points. Heat exchange through pressure change during heat transfer of hydrogen entering unit (5) The heat difference created is transferred to the heat exchange unit (5) as heat transfer gain. Gain is achieved by transferring the liquid from the inlet (4) to the heat exchange unit (5). Then, the liquid exits the heat exchange unit (5) with its temperature changed from the liquid outlet (6). This 5 Meanwhile, hydrogen enters the solenoid valve (1) heat exchange unit (5) from the inlet (3). self-ignition temperature of hydrogen and hydrogen output(7) the amount of hydrogen entering from the hydrogen inlet(3) in such a way as to prevent it from reaching its pressure settings. Thanks to sensors and solenoid valve (1), the flow, temperature and pressure are continuously monitored. The system offers safe and efficient operation.
