Description

Technical Field

[0001] This utility model relates to a safe hydrogen energy compressor, and more particularly to a safe hydrogen energy compressor with a high-efficiency heat dissipation structure, belonging to the field of hydrogen energy compressor technology. Background Technology

[0002] A hydrogen compressor is a specialized device used to compress hydrogen gas into a high-pressure state. Its main function is to convert low-pressure or atmospheric-pressure hydrogen gas into high-pressure hydrogen gas through mechanical conversion to meet the needs of various applications. These compressors typically utilize various technologies and materials to improve efficiency and compression capacity, and are widely used in fuel cell vehicles, hydrogen storage, and industrial production. There are three main types of hydrogen compressors: diaphragm compressors, liquid-driven compressors, and ion compressors. Liquid-driven reciprocating compressors, in particular, are widely used due to their simple structure and wide pressure range.

[0003] Hydraulic-driven compressors operate primarily by using hydraulic oil as the driving medium. A piston on the drive side moves a gas-pressurizing piston, drawing in and expelling gas. This process generates significant heat. Hydraulic-driven compressors mainly utilize heat dissipation fins on the casing to increase the heat dissipation area and transfer heat to the surrounding air. However, if a hydraulic-driven compressor operates for extended periods in poorly ventilated environments, the heat from the casing cannot be effectively transferred to the air quickly through the heat dissipation fins. This heat accumulation on the casing increases the overall temperature of the equipment, affecting its normal operation, reducing operational safety, and shortening its lifespan. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a safe hydrogen compressor with a highly efficient heat dissipation structure.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A safe hydrogen compressor with a high-efficiency heat dissipation structure includes a body, which includes a compression shell and an output pipe connected to the end of the compression shell. The body also includes: a plurality of heat dissipation fins (first and second) extending from both ends along the front-rear direction of the body, respectively disposed on the outer surface of the compression shell and the outer surface of the output pipe; a wind blowing assembly with its output end facing the first heat dissipation fin and used to accelerate airflow on the first heat dissipation fin; and a heat dissipation assembly disposed outside the compression shell and outside the output pipe and used to reduce the heat of the compression shell and the output pipe.

[0007] Furthermore, several heat dissipation fins are equidistantly arranged on the outside of the compression shell, and a heat dissipation channel is formed between two adjacent heat dissipation fins. The two ends of the heat dissipation channel extend along the front-back direction of the body. A heat-conducting pipe is sleeved on the outside of the output pipe, and several heat dissipation fins are equidistantly arranged on the outside of the heat-conducting pipe. A heat dissipation channel is formed between two adjacent heat dissipation fins. The two ends of the heat dissipation channel extend along the front-back direction of the body.

[0008] Furthermore, the air blowing assembly includes an annular tube, a concentrator tube, a cooling fan 1 disposed on the input end of the concentrator tube, and a duct, all sleeved on the outside of the compression housing; the annular tube is disposed at the end of the cooling fin 1 away from the cooling fin 2, and the annular tube has a hollow structure and an air outlet, the air outlet connecting the inside of the annular tube to the outside and facing the heat dissipation channel 1, and the duct connecting the output end of the concentrator tube to the input end of the annular tube.

[0009] Furthermore, an annular air guide shroud is fitted over the outside of the compression shell. The air guide shroud is located at the end of the heat dissipation fin that is away from the annular tube. The input end of the air guide shroud is connected to the first heat dissipation channel, and the output end of the air guide shroud is connected to the second heat dissipation channel.

[0010] Furthermore, the heat dissipation assembly includes a first pipe fitting sleeved on and in contact with the compression shell, a second pipe fitting sleeved on and in contact with the output end of the output pipe, a connecting pipe connecting the output end of the first pipe fitting and the input end of the second pipe fitting, and a circulating pump for circulating coolant. The output end and input end of the circulating pump are respectively connected to the input end of the first pipe fitting and the output end of the second pipe fitting.

[0011] Furthermore, the first pipe fitting includes two annular bends fitted onto the compression shell, with several connecting pipes connecting the two bends. The two ends of the connecting pipes extend along the front-rear direction of the body and are located inside the heat dissipation channel. One of the bends is connected to the output end of the circulation pump via a liquid pipe, and the other bend is connected to a connecting pipe. The second pipe fitting includes several annular bends fitted onto the outside of the output pipe, with several bends connected to each other via a conductive pipe. The connecting pipe is connected to one of the bends, and the other bend is connected to a liquid pipe.

[0012] Furthermore, a serpentine tube is connected to the output end of the second liquid pipe, and several linearly equidistant heat dissipation plates are arranged on one side of the main body. The serpentine tube passes through the heat dissipation plates and is located inside the heat dissipation plates. The output end of the serpentine tube is connected to the input end of the circulating pump.

[0013] Furthermore, a second cooling fan is provided at one end of the heat sink, and the output end of the second cooling fan faces the heat sink.

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

[0015] By installing heat dissipation fins one and two on the exterior of the compressor casing and output pipe respectively, the heat dissipation area of ​​both can be increased, which is beneficial for transferring heat to the environment. A fan assembly is installed at one end of heat dissipation fin one, accelerating airflow at the locations of heat dissipation fins one and two. Even in environments with poor airflow, this allows for air circulation around the fins, improving heat dissipation. The heat dissipation components on both fins further enhance the heat dissipation performance of the compressor casing and output pipe. Through these heat dissipation methods, even if the main unit operates for extended periods in poorly ventilated environments, heat can be transferred to the air in a timely manner, achieving rapid and efficient heat dissipation, ensuring stable and safe operation, and contributing to extending the equipment's lifespan.

[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 1-6 As shown, the safe hydrogen compressor with a high-efficiency heat dissipation structure provided in this embodiment includes a body 1. In this utility model, the body 1 refers to a liquid-driven piston compressor device among the types of safe hydrogen compressors. The body 1 includes, but is not limited to, a compression shell 101 and an output pipe 102 connected to the end of the compression shell 101. The compression shell 101 is the related structural shell for piston compression of gas. It is the structure in the body 1 where heat is concentrated and is also the heat source of heat generation on the body 1. After the gas is compressed, it will be output through the output pipe 102 mentioned above. When outputting, because the gas contains heat, the temperature of the output pipe 102 is high. The heat on the compression shell 101 and the output pipe 102 will be transferred to various parts of the body 1 along with the medium.

[0025] In order to quickly and efficiently transfer the heat on the compressor housing 101 and the output pipe 102 to the surrounding air and reduce the heat of the main body 1, the device structure also includes: several heat dissipation fins 1-2 and 2-3 extending from both ends along the front-rear direction of the main body 1, a blower assembly, and a heat dissipation assembly; specifically, several heat dissipation fins 1-2 and 2-3 are respectively disposed on the outer surface of the compressor housing 101 and the outer surface of the output pipe 102; the output end of the blower assembly faces the heat dissipation fins 1-2 and is used to accelerate the airflow on the heat dissipation fins 1-2, so that the air in the environment transfers the heat carried by the heat dissipation fins 1-2 to the air by accelerating the airflow; the heat dissipation assembly is disposed outside the compressor housing 101 and outside the output pipe 102 and is used to reduce the heat of the compressor housing 101 and the output pipe 102.

[0026] In use, by setting heat dissipation fins 1-2 and 2-3 on the outside of the compressor housing 101 and the output pipe 102 respectively, the heat dissipation area of ​​both is increased, which is conducive to the transfer of heat to the air. A fan component is set at one end of the heat dissipation fin 1-2 to accelerate the airflow at the location of the heat dissipation fin 1-2 and the heat dissipation fin 2-3. Even in environments with poor airflow, the surrounding air can be circulated to achieve the purpose of heat dissipation. The heat dissipation components on both further reduce the heat on the compressor housing 101 and the output pipe 102. Through the above heat dissipation method, even if the main body works for a long time in an environment with poor ventilation, the heat on the main body can be transferred to the air in time, achieving the purpose of rapid and efficient heat dissipation of the main body and avoiding the accumulation of heat on the main body affecting its operation.

[0027] Among them, such as Figure 3As shown, several heat dissipation fins 2 are equidistantly arranged on the outside of the compression shell 101, and a heat dissipation channel 201 is formed between two adjacent heat dissipation fins 2. The two ends of the heat dissipation channel 201 extend along the front and rear direction of the body 1. The heat dissipation fins 2 increase the heat dissipation area of ​​the compression shell 101. Several grooves 202 are provided on the heat dissipation fins 2. The grooves 202 increase the heat dissipation surface of the heat dissipation fins 2, further increasing the heat dissipation area of ​​the heat dissipation fins 2.

[0028] A heat pipe 4 is sleeved on the outside of the output pipe 102. The heat pipe 4 is preferably made of a material with excellent thermal conductivity, but this application does not limit it. Several heat dissipation fins 3 are equidistantly arranged on the outside of the heat pipe 4, and a heat dissipation channel 301 is formed between two adjacent heat dissipation fins 3. The two ends of the heat dissipation channel 301 extend along the front and rear direction of the body 1. The heat of the output pipe 102 will be transferred to the heat pipe 4, while the heat dissipation fins 3 increase the heat dissipation area of ​​the heat pipe 4, which facilitates the transfer of heat on the heat pipe 4 to the air.

[0029] To solve the airflow problem on the heat dissipation channel 201, such as Figure 4 As shown, the air blowing assembly includes an annular tube 501, a concentrator tube 502, a cooling fan 503, and a duct 504, all fitted onto the outside of the compression housing 101. Specifically, the annular tube 501 is positioned at the end of the heat dissipation fin 2 away from the heat dissipation fin 3, and has a hollow structure with an air outlet 505. The air outlet 505 connects the inside of the annular tube 501 to the outside and faces the heat dissipation channel 201. The duct 504 connects the output end of the concentrator tube 502 to the input end of the annular tube 501. The cooling fan 503 accelerates the flow of ambient air into the concentrator tube 502, and then guides it into the annular tube 501 through the duct 504. Under the action of the air outlet 505, the accelerated air is directed into the heat dissipation channel 201, accelerating the airflow within the heat dissipation channel 201.

[0030] To ensure airflow within the heat dissipation channel 2 301, such as Figure 5 As shown, the compression housing 101 is fitted with an annular air guide shroud 7. The air guide shroud 7 is located at the end of the heat dissipation fin 1 2 away from the annular tube 501. The input end of the air guide shroud 7 is connected to the heat dissipation channel 1 201, and the output end of the air guide shroud 7 is connected to the heat dissipation channel 2 301. The accelerated airflow blown out from one end of the heat dissipation channel 1 201 will be guided by the air guide shroud 7 into the heat dissipation channel 2 301, thereby accelerating the air in the heat dissipation channel 2 301, so that the heat in the heat dissipation channel 2 301 is quickly transferred to the air.

[0031] Furthermore, such as Figure 4 as well as Figure 5As shown, the heat dissipation assembly described above includes a first pipe 8 sleeved on and in contact with the compression housing 101, a second pipe 9 sleeved on and in contact with the output end of the output pipe 102, a connecting pipe 601 connecting the output end of the first pipe 8 and the input end of the second pipe 9, and a circulating pump 602 for circulating coolant. The output end and the input end of the circulating pump 602 are respectively connected to the input end of the first pipe 8 and the output end of the second pipe 9. In operation, the circulation pump 602 outputs coolant from its output end, which flows sequentially through pipe 8 and pipe 9, and then to the input end of the circulation pump 602, completing the circulation of the coolant. When the coolant is in pipe 8, it carries the heat transferred from the compressor housing 101 during its flow. When the coolant is in pipe 9, it carries the heat transferred from the output pipe 102 during its flow. Since the heat of the output pipe 102 is higher than that of the compressor housing 101, the heat on the compressor housing 101 will not affect the output pipe 102. When the coolant carries the heat from the compressor housing 101 and the output pipe 102, the heat of the coolant is transferred to the air through pipe 8 and pipe 9, accelerating the dissipation of heat from the compressor housing 101 and the output pipe 102.

[0032] Among them, pipe fitting 8 includes two annular bends 801 sleeved on the compression shell 101. Several connecting pipes 802 are connected between the two bends 801. The two ends of the connecting pipes 802 extend along the front-back direction of the body 1 and are located inside the heat dissipation channel 201. One bend 801 is connected to the output end of the circulation pump 602 through a liquid pipe 603. The other bend 801 is connected to the connecting pipe 601. Pipe fitting 9 includes several annular bends 901 sleeved on the outside of the output pipe 102. Several bends 901 are connected to each other through a conductor pipe 902. The connecting pipe 601 is connected to one of the bends 901. A liquid pipe 604 is connected to the other bend 901.

[0033] To more effectively and quickly transfer the heat carried by the coolant to the air, such as Figure 2 As shown, a serpentine tube 10 is connected to the output end of the liquid pipe 604. Several heat dissipation plates 11 are arranged linearly and equidistantly on one side of the main body 1. The serpentine tube 10 passes through the heat dissipation plate 11 and is located inside the heat dissipation plate 11. The output end of the serpentine tube 10 is connected to the input end of the circulating pump 602. By setting the heat dissipation plate 11 outside the serpentine tube 10, the heat dissipation area of ​​the serpentine tube 10 is further increased, which is beneficial to the cooling of the coolant.

[0034] In addition, a second cooling fan 12 is provided at one end of the heat sink 11, and the output end of the second cooling fan 12 faces the heat sink 11. The second cooling fan 12 accelerates the airflow in the gap between the heat sink 11, thereby accelerating the heat dissipation on the heat sink 11 and ensuring that the heat of the serpentine tube 10 can be dissipated quickly.
