Description

Technical Field

[0001] This utility model relates to the field of temperature control technology for liquid-driven hydrogen compressors, specifically to a temperature control unit module for liquid-driven hydrogen compressors. Background Technology

[0002] A common problem with liquid-driven hydrogen compressors is excessively high exhaust temperatures. High exhaust temperatures prevent the equipment from operating stably for extended periods, and reduce the overall efficiency of the compressor. Non-metallic components inside the hydrogen compressor are prone to aging, deterioration, or deformation, reducing their lifespan and consequently increasing maintenance workload and costs. Sealing elements inside the compressor are also more susceptible to damage and leakage at high temperatures. If leaked hydrogen mixes with air and reaches a critical concentration, it can lead to an explosion or fire. This poses significant challenges to daily maintenance and management, jeopardizing the safe operation of the equipment.

[0003] Research revealed that the traditional approach to solving this problem involves installing heat exchange tubes on the hydrogen pipeline and introducing a chiller to lower the temperature. However, the pipelines requiring cooling are not only long but also have a complex layout, making it extremely difficult to select suitable installation locations and spaces for the heat exchange tubes. This further exacerbates the complexity of the internal piping, making equipment installation and subsequent maintenance exceptionally cumbersome and significantly increasing the likelihood of errors.

[0004] Furthermore, a temperature control unit module for liquid-driven hydrogen compressors is proposed to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a temperature control unit module for a liquid-driven hydrogen compressor, in order to solve the problem of complex and difficult-to-maintain pipelines mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temperature control unit module for a liquid-driven hydrogen compressor, comprising heat exchange tubes and a water inlet pipe. Eight sets of heat exchange tubes are arranged, with stainless steel short pipes installed between them. A compression fitting is fixedly installed on the outer side of each heat exchange tube. Right-angle elbows are installed at both ends of each heat exchange tube, and stainless steel pipes are fixedly installed on the right-angle elbows. A low-pressure filter is fixedly connected to the starting end of each heat exchange tube, and a high-pressure filter is fixedly connected to the ending end of each heat exchange tube. A bracket is installed at the bottom of each heat exchange tube, and a water inlet pipe and a water return pipe are installed at the bottom of the bracket. The water return pipe is located below the water inlet pipe. A high-pressure hydrogen end cooling water inlet pipe and a low-pressure hydrogen end cooling water inlet pipe are respectively installed between the heat exchange tubes and the water inlet pipe. A high-pressure... The system includes a hydrogen-side cooling water outlet pipe and a low-pressure hydrogen-side cooling water outlet pipe. A flow meter is installed on the inlet pipe, and a thermometer is installed on the return pipe. The input end of the heat exchange tube has a high-pressure hydrogen inlet and a low-pressure hydrogen inlet, and the output end of the heat exchange tube has a high-pressure hydrogen outlet and a low-pressure hydrogen outlet. A cooling water inlet is fixedly installed at the inlet of the inlet pipe, and a cooling water outlet is fixedly installed at the inlet of the return pipe. A hydraulic station cooling water inlet is installed at the front end of the inlet pipe, and a hydraulic station cooling water outlet is installed at the front end of the return pipe. From left to right, the top end of the inlet pipe has a low-pressure hydrogen-side cooling water inlet, a turbocharger cooling water inlet, and a high-pressure hydrogen-side cooling water inlet. From left to right, the top end of the return pipe has a low-pressure hydrogen-side cooling water outlet, a turbocharger cooling water outlet, and a high-pressure hydrogen-side cooling water outlet.

[0007] As a further technical solution of this utility model, the high-pressure hydrogen end cooling water outlet pipe is fixedly connected to the low-pressure hydrogen end cooling water inlet and the heat exchange pipe.

[0008] As a further technical solution of this utility model, the low-pressure hydrogen end cooling water inlet pipe is connected to the high-pressure hydrogen end cooling water inlet and the heat exchange pipe respectively.

[0009] As a further technical solution of this utility model, the cooling water inlet of the hydraulic station enters the hydraulic station to cool it down and then returns to the return water pipe from the cooling water outlet of the hydraulic station.

[0010] As a further technical solution of this utility model, the turbocharger cooling water inlet enters the heat exchange tube of the turbocharger to cool it down, and then returns to the return water pipe from the turbocharger cooling water outlet.

[0011] As a further technical solution of this utility model, the low-pressure hydrogen end cooling water inlet enters the heat exchange tube through the high-pressure hydrogen end cooling water outlet pipe.

[0012] As a further technical solution of this utility model, the high-pressure hydrogen end cooling water inlet enters the heat exchange tube through the low-pressure hydrogen end cooling water inlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the temperature control unit module applied to the liquid-driven hydrogen compressor not only realizes the functions of easy installation and convenient maintenance;

[0014] By incorporating both hydrogen and circulating water pipelines, the complex piping distributed within the compressor housing is integrated into a smaller module, reducing the overall complexity of the equipment and making installation and maintenance more convenient. Modules can be adjusted or added as needed, making the product more flexible and adaptable, significantly improving design efficiency. Individual testing is possible, allowing for rapid problem detection and localization, thus enhancing product reliability. During the final assembly of the compressor equipment, only four gas line connectors and six water line interfaces corresponding to the module need to be connected, eliminating the need for operators to understand the internal piping before installation. This simplifies the entire operation process, greatly improving installation accuracy and efficiency. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 A temperature control unit module for a liquid-driven hydrogen compressor includes heat exchange tubes 5 and water inlet pipes 8. Eight sets of heat exchange tubes 5 are arranged, with stainless steel short pipes 4 installed between them. A compression fitting 14 is fixedly installed on the outer side of each heat exchange tube 5. Right-angle elbows 2 are installed at both ends of each heat exchange tube 5, with stainless steel pipes 3 fixedly installed on the right-angle elbows 2. A low-pressure filter 1 is fixedly connected to the starting end of each heat exchange tube 5, and a high-pressure filter 15 is fixedly connected to the ending end. A bracket 16 is installed at the bottom of each heat exchange tube 5, with a water inlet pipe 8 and a return water pipe 9 installed at the bottom of the bracket 16. The return water pipe 9 is located below the water inlet pipe 8. A high-pressure hydrogen end cooling water inlet pipe 7 and a low-pressure hydrogen end cooling water inlet pipe 10 are installed between each heat exchange tube 5 and the water inlet pipe 8, respectively. A high-pressure hydrogen end cooling water outlet pipe 6 and a low-pressure hydrogen end cooling water outlet pipe 9 are installed between each heat exchange tube 5 and the return water pipe 9, respectively. A flow meter 12 is installed on the outlet pipe 11 and the inlet pipe 8. A thermometer 13 is installed on the return pipe 9. A high-pressure hydrogen inlet 17 and a low-pressure hydrogen inlet 20 are installed at the input end of the heat exchange pipe 5. A high-pressure hydrogen outlet 18 and a low-pressure hydrogen outlet 19 are installed at the output end of the heat exchange pipe 5. A cooling water inlet 21 is fixedly installed at the inlet of the inlet pipe 8. A cooling water outlet 22 is fixedly installed at the inlet of the return pipe 9. A hydraulic station cooling water inlet 23 is installed at the front end of the inlet pipe 8. A hydraulic station cooling water outlet 24 is installed at the front end of the return pipe 9. From left to right, a low-pressure hydrogen end cooling water inlet 27, a booster cooling water inlet 25, and a high-pressure hydrogen end cooling water inlet 29 are installed at the top of the inlet pipe 8. From left to right, a low-pressure hydrogen end cooling water outlet 28, a booster cooling water outlet 26, and a high-pressure hydrogen end cooling water outlet 30 are installed at the top of the return pipe 9.

[0022] The high-pressure hydrogen end cooling water outlet pipe 6 is fixedly connected to the low-pressure hydrogen end cooling water inlet 27 and the heat exchange pipe 5, respectively. The low-pressure hydrogen end cooling water inlet pipe 10 is connected to the high-pressure hydrogen end cooling water inlet 29 and the heat exchange pipe 5, respectively. The high-pressure hydrogen end cooling water inlet 29 enters the heat exchange pipe 5 through the low-pressure hydrogen end cooling water inlet pipe 10.

[0023] Specifically, such as Figure 1 and Figure 2As shown, the hydrogen pipeline route enters the module from the low-pressure hydrogen inlet 20, and is arranged in an "S" shape through the right-angle elbow 2 and stainless steel pipe 3, maximizing the length of the hydrogen pipeline within a limited space. Next, the hydrogen is filtered by the low-pressure filter 1 and enters the booster from the low-pressure hydrogen outlet 19. The booster pressurizes the hydrogen and it enters the module from the high-pressure hydrogen inlet 17, again arranged in an "S" shape through the right-angle elbow 2 and stainless steel pipe 3. Finally, it is filtered by the high-pressure filter 15 and exits from the high-pressure hydrogen outlet 18 to the compressor.

[0024] The cooling water inlet 23 of the hydraulic station enters the hydraulic station to cool it down and then returns to the return water pipe 9 from the cooling water outlet 24 of the hydraulic station. The cooling water inlet 27 of the low-pressure hydrogen end enters the heat exchange pipe 5 through the cooling water outlet 6 of the high-pressure hydrogen end. The cooling water inlet 25 of the turbocharger enters the heat exchange pipe 5 of the turbocharger to cool it down and then returns to the return water pipe 9 from the cooling water outlet 26 of the turbocharger.

[0025] Specifically, such as Figure 1 and Figure 3 As shown, the circulating water circuit is the heat exchange tube 5. Its route enters the module from the cooling water inlet 21 and then splits into four paths. It only needs to be connected to the four air circuit connectors and six water circuit interfaces corresponding to the module. The operator does not need to understand the internal piping before installation, making the whole operation process simple and easy to understand.

[0026] Working principle: In use, the first path of this utility model is as follows: First, cooling water enters the hydraulic station from the inlet pipe 8 (hydraulic station cooling water inlet 23) to cool it down, then returns to the return pipe 9 from the hydraulic station cooling water outlet 24. Second, cooling water enters the turbocharger's heat exchanger tube 5 from the turbocharger cooling water inlet 25 to cool it down, then returns to the return pipe 9 from the turbocharger cooling water outlet 26. Third, cooling water enters the heat exchanger tube 5 from the low-pressure hydrogen end cooling water inlet 27 via the high-pressure hydrogen end cooling water outlet pipe 6. The heat exchanger tubes 5 are connected by stainless steel short pipes 4 and compression fittings 14, cooling the hydrogen pipeline before it passes through the high-pressure hydrogen pipeline. The first cooling water inlet pipe 7 returns to the return water pipe 9 from the low-pressure hydrogen end cooling water outlet 28. The fourth path enters the heat exchange pipe 5 from the high-pressure hydrogen end cooling water inlet 29 via the low-pressure hydrogen end cooling water inlet pipe 10. The heat exchange pipes 5 are connected by stainless steel short pipes 4 and compression fittings 14. After cooling the hydrogen pipeline, the water returns to the return water pipe 9 from the high-pressure hydrogen end cooling water outlet 30 via the low-pressure hydrogen end cooling water outlet pipe 11. The third and fourth paths are internal connections within the module. All four water paths enter the system from the cooling water outlet 22, are cooled by a chiller, and then enter the system from the cooling water inlet 21 to cool the equipment. The circulating water path runs in the opposite direction to the hydrogen pipeline to maximize hydrogen cooling. A flow meter 12 is installed on the inlet pipe 8, and a thermometer 13 is installed on the return water pipe 9 to monitor the temperature and status of the cooling water. The other ends of the inlet pipe 8 and the return water pipe 9 need to be sealed with blind flanges.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
