Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid cooling system technology, specifically to a liquid cooling system and its sealing and waterproof structure. Background Technology
[0002] Most liquid cooling systems on the market currently use a single-layer sealing ring design between the shell and the cooling plate. When the water pressure outside the sealing ring is high, water can easily seep into the liquid cooling system. Moreover, the seeping water will accumulate inside the liquid cooling system, resulting in a decrease in the airtightness between the shell and the cooling plate. Some liquid cooling systems use a complex shell structure combined with a single-layer sealing ring to improve airtightness. However, the assembly process of liquid cooling systems with this design is usually more complicated and the production cost is higher. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a liquid cooling system and its sealing and waterproof structure, which can ensure the airtightness between the shell and the cooling water plate. It does not require complex design of the structure of the liquid cooling system shell and the cooling water plate, the installation method is relatively simple, and the production cost is low.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A sealed and waterproof structure for a liquid cooling system, the liquid cooling system including a housing and a cooling water plate, the housing and the cooling water plate cooperating to form a sealed space, the sealed and waterproof structure including multiple sealing rings disposed between the housing and the cooling water plate, wherein the first sealing ring is located on the side of the second sealing ring near the edge of the cooling water plate.
[0006] In addition, the sealing and waterproof structure proposed according to this utility model may also have the following additional technical features:
[0007] According to one embodiment of the present invention, a drainage channel is formed between the first sealing ring and the second sealing ring, and a drainage groove is provided on the cold water plate, the drainage groove being connected to the drainage channel.
[0008] According to one embodiment of the present invention, the edge of the housing is provided with a folded plane, and the sealing and waterproof structure is located between the folded plane and the cold water plate.
[0009] According to one embodiment of the present invention, the sealing ring is a waterproof rubber strip.
[0010] In addition, to achieve the above objectives, this utility model also proposes a liquid cooling system.
[0011] A liquid cooling system includes a housing, a cooling water plate, and a sealing and waterproof structure as described above, wherein the housing and the cooling water plate cooperate to form a sealed space, and the sealing and waterproof structure is located between the housing and the cooling water plate.
[0012] In addition, the liquid cooling system proposed according to this utility model may also have the following additional technical features:
[0013] According to one embodiment of the present invention, the housing includes an upper cover and a lower cover, which are formed by sheet metal processing or casting process.
[0014] According to one embodiment of the present invention, a liquid cooling pipe is embedded in the cold water plate.
[0015] According to one embodiment of the present invention, the edge of the housing is provided with a folded plane, the sealing and waterproof structure is located between the folded plane and the cold water plate, and the folded plane and the cold water plate are fixed by a locking device.
[0016] The beneficial effects of this utility model are:
[0017] This utility model's liquid cooling system features a sealed and waterproof structure. Through the arrangement of multiple sealing rings, the outer sealing ring (the first sealing ring) can withstand most of the water pressure, while the inner sealing ring (the second sealing ring) is less affected by water pressure. When all multiple sealing rings use similar materials and structures, the service life of the inner sealing ring is longer. Even if the first sealing ring fails, its presence can still block some water pressure, reducing its impact on the second sealing ring and ensuring better sealing between the shell and the cooling plate. Because the multi-layer sealing ring design can withstand the impact of high water pressure, there is no need for complex design of the liquid cooling system shell and cooling plate structure; the multi-layer sealing rings can simply be placed between the shell and the cooling plate, simplifying installation and effectively reducing production costs.

[0025] 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.
[0026] like Figure 1 As shown, a commonly used liquid cooling system includes a housing 10 and a cooling plate 20. The housing 10 and the cooling plate 20 work together to form a closed space. The cooling plate 20 can provide heat dissipation for electrical components and other devices in the closed space.
[0027] To effectively prevent external moisture from entering, ensure the airtightness between the casing 10 and the cooling plate 20, and simplify the assembly process as much as possible to reduce production costs, this utility model provides a sealed and waterproof structure 30 for a liquid cooling system. Figure 2 and 3 As shown, the sealing and waterproof structure of this utility model embodiment includes: a multi-layer sealing ring disposed between the housing 10 and the cold water plate 20, wherein the first sealing ring 31 is located on the side of the second sealing ring 32 near the edge of the cold water plate 20. The sealing ring can be a waterproof strip, such as a rubber strip or a silicone strip, etc., and this embodiment is not limited thereto.
[0028] The sealing and waterproof structure of this utility model embodiment uses a multi-layer sealing ring setup, which allows the outer sealing ring, i.e., the first sealing ring 31, to withstand most of the water pressure, while the inner sealing ring, i.e., the second sealing ring 32, is less affected by water pressure. When the multi-layer sealing rings all use similar materials and structures, the service life of the inner sealing ring is longer, which can better ensure the airtightness between the shell 10 and the cooling plate 20. Even if the first sealing ring 31 fails, its presence can still block some water pressure, reducing its impact on the second sealing ring 32. Since the multi-layer sealing ring design can adapt to the impact of large water pressure, there is no need to make complex designs to the structure of the liquid cooling system shell 10 and the cooling plate 20. The multi-layer sealing ring can simply be placed between the shell 10 and the cooling plate 20, making the installation method relatively simple and effectively reducing production costs.
[0029] like Figure 3 and Figure 4 As shown, in one embodiment of this utility model, a drainage channel 33 can be formed between the first sealing ring 31 and the second sealing ring 32. A diversion groove 21 can be provided on the cold water plate 20. The diversion groove 21 is connected to the drainage channel 33, so that after the first sealing ring 31 fails, some liquid enters the drainage channel 33 and can flow to the outside of the liquid cooling system along the diversion groove 21 on the cold water plate 20, thus avoiding liquid accumulation between the first sealing ring 31 and the second sealing ring 32.
[0030] like Figure 3 As shown, in one embodiment of the present invention, the edge of the housing 10 may be provided with a folded plane 11, and the sealing and waterproof structure 30 is located between the folded plane 11 and the cold water plate 20. Thus, the multi-layer sealing ring can first be flatly attached to the folded plane 11, and then fixed together with the housing 10 to the cold water plate 20.
[0031] In addition, to achieve the above objectives, this utility model also proposes a liquid cooling system.
[0032] like Figure 5 As shown, the liquid cooling system of this utility model embodiment includes a housing 10, a cold water plate 20, and a sealing and waterproof structure 30 as described above. The housing 10 and the cold water plate 20 cooperate to form a sealed space, and the sealing and waterproof structure 30 is located between the housing 10 and the cold water plate 20.
[0033] The liquid cooling system according to the present invention, having included the aforementioned sealed and waterproof structure 30, also possesses the aforementioned beneficial effects.
[0034] In one embodiment of this utility model, the housing 10 may include an upper cover 12 and a lower cover 13. Since the sealing and waterproof structure 30 of this utility model does not require a complex structure for the housing 10, the upper cover 12 and the lower cover 13 can be formed by sheet metal processing or casting process, and can be produced separately. In this case, the sealing and waterproof structure 30 can be located between the lower cover 13 and the cold water plate 20. To ensure the airtightness between the upper cover 12 and the lower cover 13, a sealing ring can also be provided between the upper cover 12 and the lower cover 13 for sealing.
[0035] In one embodiment of this utility model, a liquid cooling pipe 22 is embedded in the cold water plate 20, so that the liquid cooling pipe 22 does not occupy the volume of the enclosed space, which is conducive to maximizing the utilization of the enclosed space; moreover, the heat dissipation efficiency can be improved by attaching the heat dissipation electrical components to the cold water plate 20.
[0036] like Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the edge of the housing 10 is provided with a folded plane 11, and the sealing and waterproof structure 30 is located between the folded plane 11 and the cold water plate 20. The folded plane 11 and the cold water plate 20 can be fixed together by a locking device 40, such as screws, so that the locking device 40 and the sealing and waterproof structure 30 cooperate to ensure the airtightness between the housing 10 and the cold water plate 20. The locking device 40 can be as follows: Figure 6 The sealing ring 31 shown is installed between the first sealing ring 31 and the second sealing ring 32, or it can be installed on both sides of the sealing and waterproof structure 30, etc. This embodiment does not limit it.
[0037] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.
[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing" and other such terms should be interpreted broadly.
