Description

Technical Field

[0001] The present invention relates to the technical field of liquid-cooled pipe network cleaning, and specifically provides an efficient cleaning method for removing redundant substances in a long-channel complex pipe network. Background Art

[0002] In electronic equipment, the liquid-cooled pipe network is an important part of the cooling system and is used for transporting cooling media between heat dissipation devices and modules that need to be cooled. To enhance the liquid-cooling reliability of products, the liquid-cooled pipe network reduces the total number of pipe network connection interfaces of the entire product by increasing the size and integration of a single pipe network. Its structure is a bifurcated structure with long-channel characteristics. This structure has many intersections, turns, and blind ends, and the flow channels are slender structures with a maximum length dimension of more than 10 meters. The visibility of redundant substances inside and the accessibility for cleaning redundant substances are poor. It is mostly formed by welding stainless steel pipes. There are abnormal welding bead protrusions such as columnar and water droplet shapes at the welded joints of each pipeline inside the flow channel, which are prone to hanging, snagging, and accumulating redundant substances, greatly increasing the difficulty of cleaning redundant substances. With the increasing demand for the heat dissipation efficiency of electronic equipment, two-phase flow substances such as Freon are currently more commonly used as the cooling medium in the liquid-cooled pipe network. This medium requires that there be no water vapor, oil stains, chips, or other redundant substances in the flow channels of the liquid-cooled pipe network, and has high requirements for the cleanliness of the internal flow channels.

[0003] Traditional cleaning methods for redundant substances inside the pipe network include high-pressure gas flushing, water flow flushing, contact long-rod cleaning, etc. Since the internal hard pipes of this long-channel complex pipe network are welded by argon arc welding at the intersection and have many blind-end structures, abnormal welding beads accumulate at the intersections inside the pipelines. They result in poor effects of gas flushing and water flow flushing methods. Redundant substances are easily accumulated at the welding beads and blind-end parts and are difficult to clean. Moreover, after water flow flushing, the entire liquid-cooled pipe network needs to be dried to remove water (when the subsequent cooling medium inside the liquid-cooled pipeline is a two-phase flow medium such as Freon, it is required that there be no residual water inside the pipe network, otherwise it will affect the heat dissipation efficiency), with high costs and long cycles. The contact long-rod cleaning method inserts a slender rod into the internal flow channel of the pipe network and touches the redundant substances for cleaning. Due to the many turns and blind ends in the flow channels of this pipe network and the slender structure of the flow channels, a rigid long rod cannot adapt to the structural characteristics of this pipe network, so this cleaning method is not feasible.

[0004] Based on the retrieval of the above information, it can be seen that when using traditional cleaning methods to clean the long-channel complex pipe network of the cooling system, there are defects such as low efficiency, high cost, and poor cleaning quality. Therefore, an efficient cleaning method for redundant substances in a long-channel complex pipe network is specifically proposed. After accurately positioning the redundant substances, rapid and high-quality cleaning of the redundant substances is achieved. Summary of the Invention
