Description

Technical Field

[0001] The utility model relates to the technical field of fuel cell stack cooling tubes, in particular to a hydrogen energy fuel cell stack cooling tube. Background Art

[0002] The hydrogen energy stack cooling tube is an important component of the hydrogen energy stack system. It is used to control the temperature of the stack and ensure the normal operation of the stack. In the hydrogen energy stack, hydrogen and oxygen generate electricity through electrochemical reactions, and also release heat. In order to keep the stack within a suitable operating temperature range and avoid overheating resulting in performance degradation or even damage, it is necessary to use cooling tubes to effectively dissipate heat. As an important component of the thermal management system, the cooling tube can effectively reduce the temperature of the stack and reduce safety risks. By reasonably designing the structure and materials of the cooling tube, the performance of the hydrogen energy stack can be optimized, and its energy conversion efficiency and output power can be improved, thereby better meeting the energy needs of different application scenarios.

[0003] Traditional hydrogen energy stack cooling hoses (multi-pass) are formed by manual winding, which requires a lot of manpower and has low production efficiency. It cannot meet the needs of large-scale production, resulting in high costs. In addition, manual operation makes it difficult to ensure the consistency of the size, thickness and quality of each cooling hose, which can easily lead to unstable product quality problems. At the same time, cooling hoses are often connected and fixed by hot melt. Once a problem occurs in the hot melt connection, it is difficult to repair and replace it, requiring professional equipment and technical support, which increases maintenance costs and work complexity.

[0004] To this end, we have developed a new type of hydrogen energy stack cooling tube. Utility Model Content

[0013] Through the above technical solution, the waste of materials and resources caused by connection damage can be reduced, and the sustainable operation performance of the system can be improved.

[0014] The utility model is further configured that a plurality of sliding tubes are arranged in the sliding groove, one of the sliding tubes is slidably connected to the connecting block, another of the sliding tubes is fixedly connected to the connecting block, and springs are fixedly connected between the plurality of sliding tubes.

[0015] The above technical solution has strong adaptability when facing cooling hoses of different sizes, materials or specifications, making system design and improvement more flexible.

[0017] Through the above technical solution, it can be disassembled and reinstalled at any time as needed to meet different process requirements or adjust the pipeline layout.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. The utility model improves the product qualification rate and production efficiency by adjusting the raw materials (special rubber material, curtain cloth) of the cooling hose, semi-finished product process (double-sided calendering process), and molding process (hose main body roll molding, hose branch roll molding, and then overall molding). In addition, the use of conductive silicone clips and ordinary silicone can achieve good conductivity at the connection of the cooling pipe, which is beneficial to conduct current and ensure the electrical connection quality of the system.

[0020] 2. The utility model adopts a fixing part to place the first cooling pipe body and the second cooling pipe body into the through hole of the connecting block at the same time, and then drives the threaded rod to rotate by rotating the bolt on one side, so that the sliding pipe on one side in the sliding groove at the bottom of the connecting block moves toward the other sliding pipe direction, and the threaded rod moves toward the inside of the other sliding pipe.
