Description

Technical Field

[0001] This utility model relates to the field of liquid cooling plates, and in particular to a multi-channel anti-clogging liquid cooling plate assembly. Background Technology

[0002] In fields such as electronic devices, new energy vehicles, and energy storage systems, the heat dissipation requirements for heat-generating components are becoming increasingly stringent as power density continues to rise. Liquid cooling technology, with its advantages of high heat dissipation efficiency and low noise, has become the mainstream choice for high heat density scenarios.

[0003] To prevent channel blockage, traditional liquid cooling plates typically employ a filter screen at the coolant inlet to intercept impurities generated during long-term use, preventing them from entering the channel and causing blockage. However, traditional liquid cooling plate filters often have a planar structure with limited filtration area, making them prone to accumulating and clogging by metal debris and particulate impurities in the coolant, leading to reduced heat dissipation efficiency. Therefore, a multi-channel anti-clogging liquid cooling plate assembly is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-channel anti-clogging liquid cooling plate assembly, which aims to improve the problem in the prior art that "the traditional liquid cooling plate filter screen is prone to impurity accumulation and clogging due to its planar structure, which leads to a decrease in heat dissipation efficiency".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-channel anti-clogging liquid-cooled plate assembly, comprising a plate a, with plates b and c fixedly installed on the upper and lower sides of plate a by bolts; liquid-cooled pipes are provided on the inner walls of plates a, b, and c; a connecting assembly is provided at the input end of each liquid-cooled pipe; the connecting assembly includes a connector, which is fixedly connected to the input end of the liquid-cooled pipe; an outer sleeve is inserted into the inner wall of the connector; a filter screen is fixedly connected to the inner wall of the outer sleeve; the filter screen has a V-shaped cross-section; a connector is provided on the outer side of the connector; and a sealing ring is provided on the inner wall of the connector and the connector.

[0006] As a further description of the above technical solution: The connector has a threaded groove b on its outer side and a threaded groove a on its inner wall. The threaded groove a and the threaded groove b are threaded together.

[0007] As a further description of the above technical solution: An auxiliary component is fixedly connected to the outside of the connector. The auxiliary component includes a fixing member fixedly connected to the outside of the connector. The inner wall of the fixing member is hollow. A movable member is slidably connected to the inner wall of the fixing member. The inner wall of the fixing member and the movable member are elastically connected by a spring. The movable member abuts against the outside of the connector.

[0008] As a further description of the above technical solution: The movable part has multiple sets of grooves on the right side near the connector, and the connector has multiple sets of protrusions fixedly connected to the right side near the fixing part, with the protrusions and grooves interlocking.

[0009] As a further description of the above technical solution: The connector has an annular protrusion on the side away from the connector head.

[0010] As a further description of the above technical solution: A regular hexagonal protrusion is fixedly connected to the middle of the connector.

[0011] As a further description of the above technical solution: The fastener is fixedly installed on the outer side of plate b and plate c by screws.

[0012] As a further description of the above technical solution: The connector is provided with anti-slip strips on the outside.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the filter screen is designed with a V-shaped cross-section, which increases the filtration area by about 50% compared to traditional flat filter screens. This allows for more efficient interception of metal debris, particulate impurities, etc. in the coolant, preventing blockage of the liquid cooling pipes. At the same time, the V-shaped structure makes the accumulation of impurities on the filter screen appear as a "slope". The scouring force generated when the fluid flows through it makes it easier to push the impurities along the slope, reducing the probability of filter screen blockage. Furthermore, the filter screen can be completely disassembled for cleaning or replacement along with the outer casing, without disassembling the entire liquid cooling plate, which improves the convenience of maintenance.

[0014] 2. In this utility model, the moving part is elastically connected to the fixed part by a spring, and the groove of the moving part and the protrusion of the connecting part are interlocked to form a locking mechanism, which reduces the loosening of the threads caused by vibration and improves the stability of the device.

[0017] 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.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a multi-channel anti-clogging liquid cooling plate assembly, including a plate a1. Plates b2 and c3 are fixedly mounted on the upper and lower sides of plate a1 by bolts. Liquid cooling pipes 4 are provided on the inner walls of plate a1, plate b2, and plate c3. Plates a1, b2, and c3, together with the liquid cooling pipes 4, form a liquid cooling plate. Plates b2 and c3 provide contact surfaces for heat dissipation with heat sources such as batteries and chips. The two sets of liquid cooling pipes 4 serve as the main flow channels for the coolant, carrying away the heat absorbed by the plate through fluid circulation within the pipes. To achieve heat dissipation, the input end of the liquid cooling pipe 4 is provided with a connecting component 5, which includes a connector 51. The connector 51 is fixedly connected to the input end of the liquid cooling pipe 4 and is interconnected with the inside of the liquid cooling pipe 4 for conveying coolant. An outer sleeve 52 is inserted into the inner wall of the connector 51. The outer sleeve 52 fixes the filter screen 53 and forms a detachable structure, which facilitates the installation, cleaning or replacement of the filter screen 53. The front side of the outer sleeve 52 abuts against the outside of the sealing ring 55, which can prevent coolant from being discharged through the gap between the outer sleeve 52 and the connector 51.

[0019] Reference Figure 3 and Figure 4A filter screen 53 is fixedly connected to the inner wall of the outer sleeve 52. The cross-section of the filter screen 53 is set in a V shape. The filter screen 53 is used to intercept impurities such as metal chips and particles in the coolant to prevent the liquid cooling pipe 4 from clogging. At the same time, the V-shaped design increases the filtration area and uses the fluid flushing force to reduce the accumulation of impurities. The V-shaped slope structure allows impurities to slide away along the slope. Liquid can flow normally through the middle of the filter screen 53, reducing the probability of clogging. A connector 54 is provided on the outside of the connector 51 to connect to the external coolant pipe. It is fixed to the connector 51 by threads and achieves fluid sealing by sealing ring 55. Sealing ring 55 is provided on the inner wall of the connector 51 and the connector 54 to fill the gap between the connector 51 and the connector 54 to prevent coolant leakage and ensure the sealing of the fluid system. A threaded groove b57 is opened on the outside of the connector 51 and a threaded groove a56 is opened on the inner wall of the connector 54. The threaded groove a56 and the threaded groove b57 are threadedly connected to fix the connector 54 and facilitate disassembly and maintenance.

[0020] Reference Figure 3 and Figure 5 An auxiliary component 6 is fixedly connected to the outside of the connector 51. The auxiliary component 6 includes a fixing member 61 fixedly connected to the outside of the connector 51. The inner wall of the fixing member 61 is hollow, providing sliding guidance and support for the moving member 62, forming the basic frame of the auxiliary component 6. The moving member 62 is slidably connected to the inner wall of the fixing member 61. The inner wall of the fixing member 61 and the moving member 62 are elastically connected by a spring 63. The spring 63 provides elastic force, so that the moving member 62 always presses against the connector 54, ensuring the insertion state of the groove 64 and the protrusion 65, and compensating for the displacement deviation caused by vibration. The moving member 62 abuts against the outside of the connector 54. The moving member 62 is elastically connected to the fixing member 61 through the spring 63 and abuts against the outside of the connector 54. Its groove 64 is inserted into the protrusion 65 of the connector 54, forming an elastic locking mechanism.

[0021] Reference Figures 3-5 The movable part 62 has multiple sets of grooves 64 on the right side near the connector 54. The connector 54 has multiple sets of protrusions 65 fixedly connected to the right side near the fixing part 61. The protrusions 65 and the grooves 64 are interlocked, and the protrusions 65 are inserted into the grooves 64 to form a mechanical lock, which restricts the circumferential rotation of the connector 54 and constitutes an anti-loosening structure. The outer sides of the protrusions 65 and the grooves 64 are all set as arc surfaces. The side of the connector 54 away from the connector head 51 is provided with an annular protrusion for connecting the hose part of the external coolant pipe, and can be fixed by clamp. The middle of the connector 54 is fixedly connected with a regular hexagonal protrusion, which is compatible with a wrench and is easy to operate in a confined space. The fixing part 61 is fixedly installed on the outside of the plate b2 and the plate c3 by screws, which improves the stability of the fixing part 61. The outer side of the connector 54 is provided with anti-slip strips, which are easy to tighten by hand.

[0022] Working principle: During use, external coolant is introduced through connector 54 and enters liquid cooling pipe 4 through connector 51. Connector 54 and connector 51 are connected by threaded grooves a56 and b57, and sealing ring 55 ensures that there is no leakage at the interface.

[0023] The coolant flows in the liquid cooling pipe 4, absorbing the heat conducted from the heat source by plates a1, b2, and c3. The liquid cooling pipe 4 forms a three-dimensional multi-channel network on the inner wall of the three-layer plate, increasing the heat exchange area. After absorbing heat, the coolant is discharged from the other end of the liquid cooling pipe 4, enters the external heat dissipation device for cooling, and then circulates back to the liquid cooling plate.

[0024] When the coolant flows into the connector 51, it first passes through the V-shaped filter 53 inside the outer sleeve 52. The V-shaped cross-section increases the filtration area by 50% compared to a flat filter 53, which can intercept impurities such as metal shavings. The V-shaped structure causes impurities to accumulate in a "sloping" shape. The scouring force of the coolant flowing through it pushes the impurities away from the center area of ​​the filter 53, ensuring the normal operation of the filter 53. When the filter 53 needs periodic maintenance, the outer sleeve 52 can be pulled out and the filter 53 can be disassembled as a whole.

[0025] In auxiliary component 6, spring 63 pushes movable part 62 to press against connector 54, and the groove 64 of movable part 62 and the arc surface of protrusion 65 of connector 54 interlock. When equipment vibration causes connector 54 to displace, spring 63 pushes movable part 62 to slide along the arc surface of protrusion 65, maintaining the locking state.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
