Description

Technical Field

[0001] This utility model relates to a compressor, and more particularly to a circulating green hydrogen compressor, belonging to the field of compressor-related technical technology. Background Technology

[0002] The circulating green hydrogen compressor is a device specifically designed for compressing green hydrogen. It is one of the core pieces of equipment in the green hydrogen industry chain and a key component of the green hydrogen circulation system. Its main function is to maintain the efficient flow and compression storage of hydrogen within the system. Circulating green hydrogen compressors are primarily used in fuel cell systems, green hydrogen energy storage and industrial applications, and chemical production processes.

[0003] The main working principle of a circulating green hydrogen compressor is to compress hydrogen and store it in a storage container under high pressure. After compression, according to thermodynamic principles, the kinetic energy and internal energy of hydrogen molecules increase, which inevitably causes them to carry a certain amount of heat. That is, the temperature of the hydrogen will rise when it is output from the compressor. The increase in hydrogen temperature will increase the hydrogen embrittlement effect on metals and cause damage to the equipment structure. Therefore, it is usually necessary to cool down the output hydrogen.

[0004] In existing technologies, the pipes for exporting hydrogen are placed inside the heat exchanger, but this increases the length of the pipes to achieve effective heat dissipation. However, the excessively long pipes reduce the pressure of the hydrogen stored in the container, which in turn affects the hydrogen storage pressure and is detrimental to the subsequent utilization of the hydrogen. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a circulating green hydrogen compressor to solve the problem of high hydrogen temperature when the compressor outputs hydrogen.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0007] A circulating green hydrogen compressor includes a main body and further includes: an output pipe, the input end of which is connected to the output end of the main body for conveying compressed hydrogen output by the main body; a plurality of heat dissipation fins, all disposed on the outer side wall of the output pipe; a heat dissipation assembly, which, through the plurality of heat dissipation fins, is used to dissipate heat from the output pipe; and a temperature control assembly, disposed on the main body, for adjusting the temperature of the heat dissipation fins.

[0008] Furthermore, the output pipe is composed of a connecting pipe and a heat dissipation pipe connected to the output pipe of the connecting pipe. The input end of the connecting pipe is connected to the output end of the main body. Several heat dissipation fins are equidistantly connected to the outer wall of the heat dissipation pipe and extend along the axis of the heat dissipation pipe. Several heat dissipation holes are equidistantly opened on the wall of the heat dissipation pipe around its central axis.

[0009] Furthermore, the heat dissipation assembly includes a spiral tube, heat pipes, and a circulation pump; wherein, the spiral tube is disposed outside the heat dissipation pipe and in contact with the heat dissipation fins, the heat pipes are provided in a plurality of them, and their number is consistent with the number of heat dissipation holes, the heat pipes are disposed inside the heat dissipation holes, the output ends and input ends of the plurality of heat pipes are respectively connected to an annular tube, two annular tubes are respectively connected to the two ends of the spiral tube, and the circulation pump is connected to the spiral tube.

[0010] Furthermore, the temperature control assembly includes a compressor, an expansion valve, a condenser, a coil, an inlet pipe, an outlet pipe, and a second spiral tube; wherein the compressor and condenser are both located on one side of the main body, the coil is located inside the condenser, the input end of the compressor is connected to the output end of the inlet pipe, the input end of the outlet pipe is connected to the output end of the coil, the input end of the coil is connected to the output end of the compressor, the expansion valve is connected to the outlet pipe, the output end of the outlet pipe is connected to one end of the second spiral tube, the input end of the inlet pipe is connected to the other end of the second spiral tube, the second spiral tube is located outside the heat dissipation pipe, and the second spiral tube passes through the heat dissipation fins.

[0011] Furthermore, a fan bracket is provided at one end of the heat pipe, and several mounting chambers are provided on the fan bracket around the axis of the heat pipe. A cooling fan is installed on the mounting chamber, and the output end of the cooling fan faces the heat dissipation fins.

[0012] Furthermore, the inner wall of the heat dissipation pipe is provided with a plurality of ribs along the axial direction, and the plurality of ribs are equidistantly arranged around the axis of the heat dissipation pipe.

[0013] Furthermore, a sensor is provided at the output end of the heat sink, and the sensing end of the sensor extends into the heat sink.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This application connects an output pipe to the output end of a hydrogen compressor. When high-pressure hydrogen passes through, it transfers heat to the output pipe. The output pipe is equipped with a heat dissipation component and a temperature regulation component. This reduces the temperature of the passing high-pressure hydrogen. The heat dissipation component acts as a water cooler, transferring heat from the inside of the output pipe to the outside. The temperature regulation component adjusts the temperature of the output pipe, thereby controlling the heat exchange efficiency between the hydrogen and the pipe. When the hydrogen temperature is too high, the temperature regulation component significantly reduces the temperature of the output pipe. When the hydrogen temperature approaches a standard range, the component slightly reduces the temperature, saving energy while ensuring the hydrogen temperature remains within the standard range, thus achieving rapid cooling. Through the coordinated use of the heat dissipation component, temperature regulation component, and other structures, effective heat dissipation is still achieved even with a reduced output pipe length.

[0023] The technical solution of this utility model will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1-6As shown, the circulating green hydrogen compressor provided in this embodiment includes a main body 1, which is a compressor for compressing hydrogen gas. It is a common technical device in the field and will not be described in detail. After the compressor compresses the hydrogen gas, the hydrogen gas will be output from the output end of the compressor in a high-pressure state. In order to regulate the heat of the high-pressure hydrogen gas, the device also includes an output pipe, several heat dissipation fins 2, a heat dissipation component and a temperature control component. Specifically, the input end of the output pipe is connected to the output end of the main body 1 to transport the compressed hydrogen output by the main body 1. The two can be connected by flange sealing or pipe welding. The specific connection method is not limited. The main purpose is to seal the connection between the output pipe and the compressor output end and to have high pressure resistance. Several heat dissipation fins 2 are set on the outer wall of the output pipe. The heat dissipation component is used to dissipate heat from the output pipe. The heat dissipation component passes through several heat dissipation fins 2 and uses the heat dissipation fins 2 to dissipate the heat carried by the heat dissipation component from the output pipe to the surrounding environment. The temperature control component is used to adjust the temperature of the heat dissipation fins 2. In order to facilitate the control of the electrical equipment mentioned above, the device includes a controller (set on the main body 1, not shown in the figure). The controller is a very conventional module in the field. Any device that can be programmed and preset with a threshold, and outputs control commands when the threshold is exceeded to control the opening and closing of equipment, valves, etc., can be applied to this application and realize its function. This application does not limit the model, structure, installation structure and usage method of the controller.

[0025] By connecting an output pipe to the output end of a hydrogen compressor, compressed hydrogen is transported to a hydrogen storage container via the output pipe. The input end of the storage container and related structures are connected to the output end of the output pipe (not shown in the figure). Since the high-pressure hydrogen output from the compressor carries heat, this heat is transferred to the output pipe as it passes through it. Existing technologies mainly dissipate heat by increasing the heat dissipation area of ​​the output pipe, which increases its length. In this device, a heat dissipation component and a temperature regulation component are installed on the output pipe. When hydrogen flows inside the output pipe, the heat dissipation component, in conjunction with the heat dissipation fins 2, rapidly reduces the temperature of the output pipe, increasing the heat exchange efficiency between the hydrogen and the output pipe. Furthermore, the temperature regulation component adjusts the temperature of the output pipe, thereby controlling the heat exchange efficiency between the hydrogen and the output pipe. When the hydrogen temperature is too high, the temperature control component will greatly reduce the temperature of the output pipe. When the hydrogen temperature approaches the standard value range, the temperature control component will slightly reduce the temperature of the output pipe. While saving energy, it ensures that the hydrogen temperature is within the standard range, so as to achieve the purpose of rapidly cooling the hydrogen.

[0026] The output pipe consists of a connecting pipe 101 and a heat dissipation pipe 102 connected to the output pipe of the connecting pipe 101. The input end of the connecting pipe 101 is connected to the output end of the main body 1. The hydrogen gas output from the compressor flows from the connecting pipe 101 into the heat dissipation pipe 102. The connecting pipe 101 and the heat dissipation pipe 102 are integrally formed to ensure their sealing and pressure resistance. The smooth design between the heat dissipation pipe 102 and the connecting pipe 101 reduces the resistance to hydrogen flow. The length of the heat dissipation pipe 102 is not specified. The material selection for the output pipe is preferably stainless steel with high thermal conductivity and resistance to hydrogen embrittlement. Several heat dissipation fins 2 are equidistantly connected to the outer wall of the heat dissipation pipe 102 and extend along the axial direction of the heat dissipation pipe 102, increasing the external surface area of ​​the heat dissipation pipe 102 and dissipating heat using the heat dissipation pipe 102. The heat dissipation pipe 102 has a certain thickness. While ensuring the structural stability of the heat dissipation pipe 102, several heat dissipation holes 103 are equidistantly opened on the pipe wall of the heat dissipation pipe 102 around its central axis to increase the heat dissipation area.

[0027] A sensor 18 is provided at the output end of the heat sink 102. The sensing end of the sensor 18 extends into the heat sink 102. The sensor 18 is electrically connected to the controller. The sensor 18 can be a common temperature sensor in the prior art. In use, it can sense the internal temperature of the heat sink 102, and thus sense the temperature of the hydrogen flowing inside the heat sink 102. The sensor 18 will transmit the temperature signal to the controller. The controller will determine whether the temperature meets the standard after setting a pre-programmed temperature threshold. If the temperature is too high, the controller will output a control command to control the operation of the heat sink and temperature control components.

[0028] Furthermore, such as Figure 5As shown, the heat dissipation assembly includes a spiral tube 3, heat pipes 4, and a circulation pump 5. The spiral tube 3 is located outside the heat dissipation pipe 102 and contacts the heat dissipation fins 2. Several heat pipes 4 are provided, their number matching the number of heat dissipation holes 103. The heat pipes 4 are located inside the heat dissipation holes 103, with their outer walls in contact with the inner walls of the heat dissipation holes 103. Optionally, a thermally conductive material, such as thermally conductive grease, can be filled between the heat pipes 4 and the inner walls of the heat dissipation holes 103 to increase the tightness of the contact and thermal conductivity. Specific implementation depends on actual use and is not limited. Several heat pipes 4... The output and input ends are connected to a ring tube 6, and the two ring tubes 6 are connected to the two ends of the spiral tube 3. The circulation pump 5 is connected to the spiral tube 3. A heat-conducting liquid flows in the spiral tube 3 and the heat-conducting pipe 4. The heat-conducting liquid can be deionized water to avoid ion permeation and hydrogen contamination. It has a high specific heat capacity. When the water flows in the heat-conducting pipe 4 under the drive of the circulation pump 5, it will absorb the heat on the wall of the heat-conducting pipe 4 and quickly move the heat into the spiral tube 3. When the water flows in the spiral tube 3, under the action of the heat dissipation fins 2, it will dissipate the heat it carries to the surrounding environment to achieve the purpose of water cooling.

[0029] Among them, such as Figures 1-3 as well as Figure 5As shown, the temperature control assembly includes a compressor unit 7, an expansion valve 8, a condenser 9, a coil 10, an inlet pipe 11, an outlet pipe 12, and a spiral tube 2 13. The compressor unit 7 and the condenser 9 are both located on one side of the main body 1. The coil 10 is located inside the condenser 9. The input end of the compressor unit 7 is connected to the output end of the inlet pipe 11, and the input end of the outlet pipe 12 is connected to the output end of the coil 10. The input end of the coil 10 is connected to the output end of the compressor unit 7. The expansion valve 8 is connected to the outlet pipe 12, and the output end of the outlet pipe 12 is connected to one end of the spiral tube 2 13. The input end of the inlet pipe 11 is connected to the other end of the spiral tube 2 13. The spiral tube 2 13 is located outside the heat dissipation pipe 102 and passes through the heat dissipation fins 2. Refrigerant flows inside the coil 10, inlet pipe 11, outlet pipe 12, and spiral tube 2 13. The compressor unit 7 controls the refrigerant flow. Work is done to increase the pressure of the refrigerant, turning it into a liquid state. This liquid is then introduced into the coil 10 inside the condenser 9. A fan is located on one side of the condenser 9, blowing outside air onto it to lower the temperature of the refrigerant flowing in the coil 10. The refrigerant is then output through the outlet pipe 12. Upon passing through the expansion valve 8, the pressure of the refrigerant is reduced, causing it to change from a liquid state to a gas-liquid mixture. When the refrigerant is delivered to the spiral tube 13, it absorbs heat from the surrounding environment, lowering the temperature of the heat dissipation fins 2 and the heat dissipation pipe 102. This implementation technique is conventional in the field and will not be elaborated upon here. By controlling the compressor 7 and the expansion valve 8 in the temperature control assembly, the efficiency of the refrigerant in absorbing heat from the surrounding environment can be controlled, thereby controlling the heat exchange efficiency of the heat dissipation fins 2 and the heat dissipation pipe 102, rapidly reducing the heat carried out by the heat dissipation assembly, and keeping the area around the heat dissipation fins 2 at a lower temperature.

[0030] Furthermore, such as Figure 4 As shown, a fan bracket 14 is provided at one end of the heat pipe 102. Several mounting chambers 15 are provided on the fan bracket 14 around the axis of the heat pipe 102. A cooling fan 16 is installed on the mounting chamber 15. The output end of the cooling fan 16 faces the heat dissipation fin 2. The cooling fan 16 blows the outside air onto the heat dissipation fin 2. Under the action of the mounting chamber 15, the air force is guided onto the heat dissipation fin 2, accelerating the temperature loss on the heat dissipation fin 2 and achieving the effect of air cooling.

[0031] like Figure 6 As shown, a number of ribs 17 are provided on the inner wall of the heat dissipation pipe 102 along the axial direction. The number of ribs 17 are equidistantly arranged around the axis of the heat dissipation pipe 102, which increases the surface area of ​​the inner wall of the heat dissipation pipe 102 and increases the heat transfer efficiency. Moreover, the ribs 17 extend along the axial direction, so they will not affect the hydrogen transport.
