Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning equipment technology, and in particular to an internal flow channel cleaning device for liquid-cooled products. Background Technology

[0002] Liquid cooling products are widely used in industries such as communications electronics, medical equipment, new energy vehicle batteries / control systems, energy storage equipment, military electronic control products, computer electronics, and servers / data centers. They primarily utilize coolants such as water to rapidly dissipate heat generated by the device's chips, achieving rapid cooling. The cleanliness of the internal flow channels, the appropriate flow resistance, and the absence of leaks are crucial to the overall quality of the liquid cooling product. For example, cutting and welding debris from the liquid cooling process, being generally denser than the cleaning fluid, cannot be completely removed by ordinary cleaning and remains inside the product. This can lead to slow coolant circulation and affect the cooling effect. Furthermore, corrosive liquids such as acids and alkalis remaining from electroplating or oxidation processes often form laminar flows within the liquid cooling product due to its quiet internal flow, and vortices can easily form in corners, making effective cleaning impossible. This directly impacts the product's lifespan and can even lead to corrosion, perforation, and leaks, causing safety incidents.

[0003] Currently, most equipment on the market for cleaning liquid-cooled products uses a static cleaning method. This involves placing the liquid-cooled product on a cleaning rack, manually inserting the cleaning hose, turning on the water pump, waiting for a certain cleaning time, then disconnecting the hose, pouring out the cleaning fluid, and then using an air gun to dry any excess cleaning fluid. For higher-precision cleaning, a vacuum pump is used to absorb moisture for a certain period. This cleaning method is not only ineffective, but each step requires a separate piece of equipment, resulting in high costs, large space requirements, and complex operations, leading to high labor and equipment costs. Utility Model Content

[0004] Therefore, it is necessary to provide an internal flow channel cleaning device for liquid cooling products to improve the cleaning effect and cleaning quality.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution.

[0006] This utility model provides an internal flow channel cleaning device for liquid-cooled products, including a loading and unloading station, a flow resistance measuring station, a cleaning station, and a drying station. Each station is equipped with a fixture for clamping the liquid-cooled product. The flow resistance measuring station is also connected to a flow meter connected to the fixture or the outlet of the liquid-cooled product for detecting the flow resistance of the internal flow channel of the liquid-cooled product. The cleaning station is adapted to introduce hot water into the internal flow channel of the liquid-cooled product, and the fixture is adapted to rotate during the cleaning of the internal flow channel.

[0007] In the above-mentioned cleaning device, the loading and unloading station, the flow resistance measurement station, the cleaning station and the drying station are arranged in a ring and arranged in sequence, and the fixtures of each station are installed on a workbench, and the workbench drives each fixture to rotate.

[0008] In the above-mentioned cleaning device, the fixture is mounted on a drive motor, and the drive motor is adapted to drive the fixture to rotate or flip.

[0009] In the above-mentioned cleaning device, a vibration motor is disposed on the fixture, and the vibration motor is adapted to provide continuous vibration to the fixture.

[0010] In the above-mentioned cleaning device, a leak detection station is also provided between the drying station and the loading and unloading station. The leak detection station is suitable for using helium gas to detect whether there is a leak in the inner flow channel.

[0011] In the above-mentioned cleaning device, there are 2-3 cleaning stations, and each cleaning station is equipped with an independent cleaning fluid storage tank and a water pump.

[0012] In the above-mentioned cleaning device, the drying station includes a hot air blowing station and a vacuum station. The hot air blowing station is equipped with a hot air blower, and the vacuum station is equipped with a vacuuming device.

[0013] This invention employs the aforementioned cleaning device, enabling dynamic cleaning of the internal flow channels. Because the liquid-cooled product is tumbled during the cleaning process, the laminar flow within the internal flow channels is disrupted, and vortices formed in corners are dispersed, effectively carrying away debris and other impurities. This ensures thorough cleaning of every part of the internal flow channels, achieving high-cleanliness cleaning. Simultaneously, the integration of loading / unloading, dynamic cleaning, and drying processes not only effectively reduces the equipment's footprint but also improves cleaning efficiency and reduces labor and equipment costs. Attached Figure Description

[0014] Figure 1 This is a perspective view of the internal flow channel cleaning device of the liquid-cooled product in this embodiment of the present invention;

[0015] Figure 2 This is a plan view of the internal flow channel cleaning device of the liquid-cooled product in this embodiment of the utility model;

[0016] Figure 3 This is a schematic diagram of the cleaning station in an embodiment of the present invention.

[0017] The purpose of this utility model, as well as its functions and principles, will be further explained in conjunction with the accompanying drawings in specific embodiments. Detailed Implementation

[0018] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details.

[0019] Reference Figure 1 As shown, this embodiment provides an internal flow channel cleaning device 100 for a liquid-cooled product 200, including a loading / unloading station 1, a flow resistance measuring station 2, a cleaning station 3, and a drying station 4. Each station is equipped with a flip-up or rotatable fixture 10 for clamping the liquid-cooled product. The flow resistance measuring station 2 is also connected to a flow meter (not shown) to the fixture 10 or the outlet of the liquid-cooled product 200 for detecting the flow resistance of the internal flow channel of the liquid-cooled product 200. When the flow resistance of the internal flow channel is detected to be greater than a predetermined value (or the flow rate is less than a predetermined value), it is identified as a defective product and an alarm signal is automatically issued, or a stop signal is directly issued to stop the equipment, so that the operator can remove it and replace it with another liquid-cooled product 200 for continued testing.

[0020] The cleaning station 3 is suitable for introducing hot water into the liquid-cooled product 200, cleaning the inner flow channels of the liquid-cooled product 200 while the fixture 10 is rotated. Because a tumbling motion is added during the cleaning process, debris and other impurities will not accumulate, thus effectively removing impurities and achieving efficient cleaning of the inner flow channels of the liquid-cooled product. In this embodiment, the tumbling axis of the fixture 10 is substantially parallel to the extension direction of the inner flow channels, further preventing impurity deposition. The extension direction of the inner flow channels refers to the direction from the inlet to the outlet of the inner flow channels.

[0021] Furthermore, in this embodiment, cleaning station 3 employs multiple high-temperature water cleaning processes, occupying 2-3 stations, to ensure the products are cleaned more thoroughly. Each cleaning process uses an independent storage tank with heating function to store the cleaning solution, and is equipped with an independent water pump for extraction. The storage tank is also equipped with a filtration system to remove impurities, and a pH meter is installed to monitor the pH of the cleaning solution. When the pH reaches the set value, the cleaning solution is replaced to ensure that the pH of the flow channels in each liquid-cooled product does not exceed the standard.

[0022] Drying station 4 is used for vacuuming the inner flow channel of the cleaned liquid-cooled product. The drying station includes a hot air blowing station 41 and a vacuuming station 42. The hot air blowing station 41 is equipped with a hot air blower, and the vacuuming station 42 is equipped with a vacuuming device. Drying station 4 utilizes the low boiling point of water under vacuum and the residual heat from the product after hot air heating to dry the inner flow channel. This eliminates the need for additional dedicated drying equipment and corresponding fixtures, and also eliminates the need for secondary clamping, greatly improving work efficiency and reducing production costs.

[0023] like Figure 2As shown, the loading / unloading station 1, flow resistance measurement station 2, cleaning station 3, and drying station 4 are arranged in a ring and sequentially, and the fixtures 10 of each station are mounted on a workbench 20, which drives the fixtures 10 to rotate. This structure enables seamless continuous operation of each process, effectively improving work efficiency.

[0024] Reference Figure 3 The fixture 10 is mounted on a drive motor 30, which can drive the fixture 10 to rotate or flip. The drive motor 30 is small in size and easy to install, making it very suitable for integration into structures such as the fixture 10.

[0025] To further improve the cleaning effect, this embodiment also includes a vibration motor 40 on the fixture 10, which vibrates continuously during the cleaning process. The vibration disrupts the laminar flow formed in the internal channels of the liquid-cooled product 200 and disperses the vortices formed in the corners, thereby cleaning as many corners as possible inside the liquid-cooled product 200.

[0026] In addition, a leakage detection station 5 is also provided between the drying station 4 and the loading / unloading station 1 (e.g., Figure 2 The leak detection station 5 is used to detect whether there are leaks in the internal flow channel using helium gas. Products with leaks can be removed and scrapped immediately.

[0027] To ensure the accuracy of gas detection, drying station 4 is also equipped with a dryness and humidity detector to check whether the internal flow channel of the liquid-cooled product has reached the required dryness.

[0028] In summary, this utility model, employing the aforementioned cleaning device, can achieve dynamic cleaning of the internal flow channels. Because the liquid-cooled product is tumbled during the cleaning process, the laminar flow formed within the internal flow channels is disrupted, and vortices formed in the corners are dispersed, effectively carrying away debris and other impurities. This ensures thorough cleaning of every part of the internal flow channels, achieving high-cleanliness cleaning. Furthermore, the integration of loading / unloading, dynamic cleaning, and drying processes into a single device not only effectively reduces the equipment's footprint but also improves cleaning efficiency and reduces labor and equipment costs.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
