TECHNICAL FIELD

[0001] The utility model relates to liquid cooling sealing technical field, concretely relates to a kind of sealing structure and liquid cooling transformer for liquid cooling pipeline in liquid cooling cabinet. BACKGROUND

[0002] In liquid cooling cabinet, liquid cooling assembly is used to heat generating device in the cabinet to dissipate heat, and in order to form a chamber with waterproof and dustproof performance in the cabinet, a sealing plate is also provided in the cabinet, which closes part of the space in the cabinet to form a closed chamber. In some cases, the heat sink in the liquid cooling assembly is arranged in the closed chamber, but the cooling liquid of the liquid cooling assembly needs to be transported outside the closed chamber, so the liquid cooling pipeline for transporting cooling liquid in the liquid cooling assembly needs to pass through the sealing plate. When using hard liquid cooling pipeline, such as using metal liquid cooling pipeline, the liquid cooling pipeline in the closed chamber needs to pass through the opening on the sealing plate and be connected to another pipeline through a quick connector. However, due to assembly precision or welding problems of metal liquid cooling pipeline, the liquid cooling pipeline cannot always be accurately aligned with the opening on the sealing plate, so the liquid cooling pipeline cannot be tightly matched with the sealing ring at the opening, which may cause water leakage at the opening. SUMMARY

[0003] The utility model aims at overcoming the above-mentioned defects or problems in the background art, and provides a sealing structure for liquid cooling pipeline in liquid cooling cabinet and liquid cooling transformer, which can improve the water leakage of liquid cooling pipeline at the opening of the sealing plate.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] Technical solution one: a sealing structure for liquid cooling pipeline in liquid cooling cabinet, which is used to realize the sealing connection between the liquid cooling pipeline and the sealing plate, comprising a sealing member; the sealing member is formed by a side wall with elasticity around the first direction, and a first opening and a second opening are formed at both ends of the sealing member in the first direction; the second opening is matched with the liquid cooling pipeline; the sealing member is connected with the sealing plate only at the position of the first opening.

[0006] Technical solution two based on technical solution one: the sealing member is provided with a connecting part suitable for holding the liquid cooling pipeline at the position of the second opening, and the connecting part is arranged along the first direction.

[0007] Technical solution three based on technical solution two: the side wall of the sealing member includes an extension part extending obliquely to the first direction, and the extension part is tapered from the position of the first opening to the position of the second opening; the size of the second opening is smaller than that of the first opening.

[0008] Based on the technical solution three, the connecting part is arranged on the side wall of the sealing member and smoothly connects with the extending part.

[0009] Based on the technical solution four, the sealing member is formed with an elastic section at at least one part of the extending part, and the side wall is continuously bent towards the inside and outside of the sealing member at the elastic section.

[0010] Based on the technical solution four or five, the sealing member is provided with a connecting flange plate at the first opening, and the connecting flange plate is adapted to pass through the opening of the sealing plate to be fixed to the sealing plate through the connecting flange plate.

[0011] Based on the technical solution six, the sealing gasket is further arranged between the connecting flange plate and the sealing plate to seal the gap between the connecting flange plate and the sealing plate.

[0012] Based on the technical solution seven, the inner wall of the connecting part of the sealing member and the outer wall of the liquid cooling pipeline are closed by the sealing glue.

[0013] Based on the technical solution eight, the tightening hoop is further arranged outside the connecting part of the sealing member to make the sealing member tightly hold the liquid cooling pipeline.

[0014] In addition, the present application further provides a technical solution ten: a liquid cooling converter, comprising a liquid cooling cabinet, a converter and a liquid cooling assembly, the converter and the liquid cooling assembly are arranged in the liquid cooling cabinet, the liquid cooling assembly is used for conveying cooling liquid through the liquid cooling pipeline and cooling the converter, the liquid cooling cabinet is provided with a sealing plate for separating a cavity, and the sealing structure for the liquid cooling pipeline in the liquid cooling cabinet is used to realize the sealing connection between the liquid cooling pipeline and the sealing plate.

[0015] From the above description of the present application, the present application has the following beneficial effects compared with the prior art:

[0016] The technical solution one provides a sealing structure for a liquid cooling pipe in a liquid cooling cabinet. The sealing member of the sealing structure is formed by a side wall with elasticity surrounding a first direction, and is provided with a first opening and a second opening. The sealing member is connected with the sealing plate only at the position of the first opening, so that the other part of the sealing member is in a suspended state, which provides a space for the elastic deformation of the main part of the sealing member. The second opening of the sealing member can be sleeved with the liquid cooling pipe. After the liquid cooling pipe is inserted into the second opening, the sealing member can hold the outer wall of the liquid cooling pipe, so as to form a seal between the liquid cooling pipe and the opening of the sealing plate. When the position of the liquid cooling pipe deviates from the opening of the sealing plate, the second opening can still be sleeved with the liquid cooling pipe through the deformation of the side wall of the sealing member, because the side wall of the sealing member has elasticity and a certain length.

[0017] In the technical solution two, the connecting part extending along the first direction is arranged on the sealing member. The connecting part increases the contact area between the sealing member and the liquid cooling pipe, reduces the risk of gap between the sealing member and the liquid cooling pipe, and improves the sealing effect of the sealing member on the liquid cooling pipe.

[0018] In the technical solution three, the side wall of the sealing member includes an extension part extending obliquely relative to the first direction, and the extension part is in a converging shape. When the position of the liquid cooling pipe deviates from the opening of the sealing plate, the deformation of the sealing member is smaller relative to other shapes, so that a stress concentration area is less likely to be formed on the sealing member. The stress concentration area can cause deformation of the sealing member at other positions, resulting in sealing failure of the second opening and the liquid cooling pipe. The first opening of the sealing member is larger than the second opening, so that the sealing member is matched with the opening of the sealing plate, and the liquid cooling pipe in the sealing member is connected by a quick connector.

[0019] In the technical solution four, the connecting part is arranged on the side wall of the sealing member and smoothly connected with the extension part. The sealing member is in a circular truncated cone shape, so that the sealing member is easily demolded.

[0020] In the technical solution five, the sealing member is provided with an elastic section. The bending structure of the elastic section improves the deformation ability of the side wall of the sealing member, and the elastic section is deformed only at the position of the elastic section, so that the sealing effect is not reduced due to the pulling of the second opening.

[0021] In the technical solution six, the sealing member is provided with a connecting flange plate, so that the sealing member is fixed to the sealing plate.

[0022] In the technical solution seven, a sealing gasket is arranged between the connecting flange plate and the sealing plate, so that the sealing performance between the sealing member and the sealing plate is improved.

[0023] In the technical solution eight, the inner wall of the connecting part of the sealing member and the outer wall of the liquid cooling pipe are closed by a sealing glue, so that the sealing effect between the sealing member and the liquid cooling pipe is further improved.

[0024] In the ninth technical solution, the tightening hoop is arranged outside the connecting portion of the sealing member to improve the sealing effect between the sealing member and the liquid cooling pipeline.

[0025] The tenth technical solution provides a liquid cooling transformer, which adopts the sealing structure for the liquid cooling pipeline in the liquid cooling cabinet, and can improve the poor sealing effect caused by the misalignment between the liquid cooling pipeline and the opening on the sealing plate of the liquid cooling cabinet in the liquid cooling assembly.

[0038] The utility model discloses a kind of sealing structures for liquid cooling pipeline in liquid cooling cabinet, which is used to realize the sealing connection between liquid cooling pipeline 1 and sealing plate 2.

[0039] Among them, it is necessary to explain the structure of liquid cooling cabinet and liquid cooling pipeline 1 to understand the implementation basis of the sealing structure.

[0040] Liquid cooling cabinet refers to the electrical cabinet using liquid cooling heat dissipation mode, and the type of the electrical cabinet can be energy storage cabinet, current conversion cabinet, etc. No matter what type it is, the electrical cabinet is provided with electrical elements needing heat dissipation inside, for example, power assembly is arranged in current conversion cabinet, and IGBT module in power assembly generates a large amount of heat when working. These heat can be taken away by liquid cooling heat dissipation mode to ensure the normal work of power assembly. Liquid cooling heat dissipation mode is generally realized by liquid cooling assembly, and the liquid cooling assembly includes liquid cooling heat exchanger, liquid cooling radiator and liquid cooling pipeline 1. The liquid cooling heat exchanger is generally arranged outside the liquid cooling cabinet, the liquid cooling radiator is arranged on the electrical element needing heat dissipation, and the liquid cooling pipeline 1 is used to transport cooling liquid. Cooling liquid is cooled and reduced in temperature at liquid cooling heat exchanger, and absorbs heat and increases in temperature at liquid cooling radiator.

[0041] Among them, some liquid cooling cabinets have higher requirements for internal dustproof and waterproof performance, so the corresponding chamber is separated in the liquid cooling cabinet by the sealing plate 2, the chamber inside the sealing plate 2 has higher dustproof and waterproof performance, and the part outside the sealing plate 2 can be communicated with the outside or has lower dustproof and waterproof performance. At the same time, the liquid cooling pipeline 1 needs to be stretched out from the chamber with higher dustproof and waterproof performance in the liquid cooling cabinet to the chamber with lower dustproof and waterproof performance in the liquid cooling cabinet, which makes the liquid cooling pipeline 1 need to pass through the opening 12 on the sealing plate 2.

[0042] And when the liquid cooling pipeline 1 adopts metal material, due to assembly precision or welding problem of metal material liquid cooling pipeline 1, the liquid cooling pipeline 1 cannot always accurately align the opening 12 on the sealing plate 2, so the liquid cooling pipeline 1 cannot tightly cooperate with the sealing rubber ring at the opening 12, which leads to water leakage at the opening 12 position.

[0043] The above is the implementation basis of the sealing structure of the liquid cooling pipeline in the liquid cooling cabinet involved in the embodiment.

[0044] On this basis, the sealing structure of the liquid cooling pipeline in the liquid cooling cabinet involved in the embodiment is described.

[0045] Referring to Figure 1 and Figure 2 The sealing structure includes a sealing member 3; the sealing member 3 is surrounded by the side wall 4 with elasticity in the first direction, and the first opening 5 and the second opening 6 are respectively formed at both ends of the sealing member 3 in the first direction; the second opening 6 is sleeved and matched with the liquid cooling pipeline 1; and the sealing member 3 is connected with the sealing plate 2 only at the position of the first opening 5.

[0046] Among them, the liquid cooling pipeline 1 at this position is a tubular member, one end of which can be connected with a liquid cooling radiator, and one end is stretched out of the sealing plate 2 and connected with other pipelines through a quick connector. The sealing plate 2 is provided with an opening 12, and the size of the opening 12 is greater than the outer diameter of the liquid cooling pipeline 1, so as to facilitate the liquid cooling pipeline 1 to stretch out from the opening 12, and even if the liquid cooling pipeline 1 does not face the opening 12, it will not affect the liquid cooling pipeline 1 to stretch out from the opening 12.

[0047] The main part of the sealing member 3 is enclosed by the side wall 4 in the first direction, and the first opening 5 and the second opening 6 are formed at both ends of the first direction respectively, wherein the size of the second opening 6 is matched with the outer diameter of the liquid cooling pipeline 1, and the liquid cooling pipeline 1 can be inserted into the second opening 6 and form a sealing fit with the sealing member 3. The first direction is the extension direction of the side wall 4, or the axial direction of the first opening 5 and the second opening 6. At the same time, the sealing member 3 is connected with the sealing plate 2 at the position of the first opening 5, and more specifically, the sealing member 3 is connected with the opening 12 on the sealing plate 2, so that the channel in the sealing member 3 can connect the inside and outside of the sealing plate 2, and when the liquid cooling pipeline 1 is inserted from the second opening 6, the liquid cooling pipeline 1 can be connected with the sealing plate 2 through the quick connector on the outside of the sealing plate 2. The key is that the sealing member 3 is connected with the sealing plate 2 only at the position of the first opening 5, and since the sealing member 3 has a certain length in the first direction, the other part of the sealing member 3 will be in a suspended state at this time, which provides space for the main part of the sealing member 3 to be elastically deformed, and at the same time, the second opening 6 of the sealing member 3 can be sleeved with the liquid cooling pipeline 1. After the liquid cooling pipeline 1 is inserted into the second opening 6, the sealing member 3 will hold the outer wall of the liquid cooling pipeline 1, so that the liquid cooling pipeline 1 and the opening 12 of the sealing plate 2 form a seal, and when the position of the liquid cooling pipeline 1 deviates from the opening 12 of the sealing plate 2, since the side wall 4 of the sealing member 3 has elasticity and a certain length, the second opening 6 can still be sleeved with the liquid cooling pipeline 1 through the deformation of the side wall 4 of the sealing member 3.

[0048] Referring to Figure 3 In one aspect of the sealing structure for the liquid cooling pipeline in the liquid cooling cabinet, the sealing member 3 is provided with a connecting part 7 suitable for holding the liquid cooling pipeline 1 at the position of the second opening 6, and the connecting part 7 is arranged in the first direction. The side wall 4 of the sealing member 3 includes an extension part 8 extending obliquely relative to the first direction, and the extension part 8 is tapered from the position of the first opening 5 to the position of the second opening 6. The size of the second opening 6 is smaller than that of the first opening 5. The connecting part 7 is arranged on the side wall 4 of the sealing member 3 and smoothly connects with the extension part 8.

[0049] Specifically, the main part of the sealing member 3 is a two-end opening cylindrical structure enclosed by the side wall 4, and the size of the end forming the first opening 5 is large, and the size of the end forming the second opening 6 is small. The side wall 4 forms an extension part 8 extending obliquely between the first opening 5 and the second opening 6, and a connecting part 7 extending in the first direction is formed between the extension part 8 and the second opening 6, and the connecting part 7 and the extension part 8 are smoothly connected, so that the sealing member 3 as a whole looks like a table shape with a narrow top and a wide bottom from the side. The smooth connection structure facilitates the demolding of the sealing member 3.

[0050] The liquid cooling pipe 1 extends into the sealing member 3 from the second opening 6, and the outer wall of the liquid cooling pipe 1 is in contact with the inner wall of the connecting part 7 at the position of the second opening 6. Since the connecting part 7 extends along the first direction, and even if the liquid cooling pipe 1 deviates from the position of the opening 12 on the sealing plate 2, the general extension direction of the liquid cooling pipe 1 is also along the first direction, so that the inner wall of the connecting part 7 can be in close contact with the outer wall of the liquid cooling pipe 1. In addition, compared with the overall regular table-shaped structure of the sealing member 3, the contact area is larger, which can reduce the risk of gap between the sealing member 3 and the liquid cooling pipe 1, thereby improving the sealing effect of the sealing member 3 on the liquid cooling pipe 1.

[0051] In addition, the extension part 8 of the sealing member 3 is in a converging shape. When the liquid cooling pipe 1 deviates from the position of the opening 12 on the sealing plate 2, the deformation of the sealing member 3 is smaller relative to the cylindrical shape of the sealing member 3, and it is less likely to form a stress concentration area on the sealing member 3. The stress concentration area can cause deformation of the sealing member 3 at other positions, resulting in failure of the sealing of the second opening 6 and the liquid cooling pipe 1. The size of the first opening 5 of the sealing member 3 is greater than the size of the second opening 6, which facilitates the adaptation of the sealing member 3 to the opening 12 on the sealing plate 2, and facilitates the connection of the liquid cooling pipe 1 in the sealing member 3 by the practical quick connector.

[0052] Referring to Figure 4 As another aspect of the sealing structure for the liquid cooling pipe in the liquid cooling cabinet, the sealing member 3 is formed with an expansion section 9 at at least one position of the extension part 8, and the side wall 4 of the expansion section 9 is continuously bent towards the inside and outside of the sealing member 3. Specifically, the expansion section 9 is arranged on the extension part 8 of the sealing member 3, which can be consistent with the length of the extension part 8, or slightly smaller than the extension part 8, and the expansion section 9 should be arranged around the circumference of the side wall 4 of the sealing member 3. The structure of the expansion section 9 is continuously bent towards the inside and outside, and when the sealing member 3 is not stressed, part of the expansion section 9 remains in the bent structure. When the sealing member 3 is stressed, the original bent structure of the expansion section 9 deforms, thereby providing greater deformation capacity and avoiding the pulling of part of the second opening 6 to cause a decrease in the sealing effect.

[0053] Further, the sealing member 3 is provided with a connecting flange 10 at the first opening 5, and the connecting flange 10 is adapted to penetrate the opening 12 on the sealing plate 2 to be fixed to the sealing plate 2 by the connecting flange 10. Specifically, referring to Figure 1The side wall 4 of the sealing member 3 has an edge at the position of the first opening 5, and the connecting flange 10 is formed outwardly from the edge. The outer edge of the connecting flange 10 is obviously located outside the side wall 4 of the sealing member 3. When the sealing member 3 is installed, the sealing member 3 is passed through the opening 12 from the outside of the cover plate 2, and the connecting flange 10 is clamped on the cover plate 2. At this time, the side wall 4 of the sealing member 3 is located inside the cover plate 2, and the connecting flange 10 is located outside the cover plate 2. The connecting flange 10 is fixed on the cover plate 2 by bolts or rivets, so that the sealing member 3 is fixedly connected with the cover plate 2 only at the position of the first opening 5. The connecting flange 10 can be integrally formed with the side wall 4, or can be connected with the side wall 4 after the side wall 4 is formed. The material of the connecting flange 10 can be different from that of the side wall 4, and the connecting flange 10 can be made of rubber or metal.

[0054] As a preferred embodiment, a sealing gasket 11 can be further provided, which is suitable for being laid between the connecting flange 10 and the cover plate 2 to seal the gap between the connecting flange 10 and the cover plate 2. Referring to Figure 1 The sealing gasket 11 has an opening in the middle to facilitate the connection of the liquid cooling pipe 1 extending out through the quick connector. Before the sealing member 3 is installed, the sealing gasket 11 can be attached to the outside of the cover plate 2, and the opening in the sealing gasket 11 is positioned corresponding to the opening 12 in the cover plate 2. Then, the connecting flange 10 is locked on the cover plate 2, and the connecting flange 10 and the cover plate 2 cooperatively hold the sealing gasket 11. The material of the sealing gasket 11 can be rubber or silicone.

[0055] Preferably, when the liquid cooling pipe 1 extends into the second opening 6, the inner wall of the connecting portion 7 of the sealing member 3 and the outer wall of the liquid cooling pipe 1 are sealed by a sealing glue. The sealing glue 3 can be glass glue, hot melt glue, etc. The sealing glue not only plays a sealing role, but also plays a role of bonding the outer wall of the liquid cooling pipe 1 and the inner wall of the sealing member 3, so as to avoid the separation of the liquid cooling pipe 1 and the sealing member 3.

[0056] Alternatively, a tightening hoop can be provided, which is used to hoop the connecting portion 7 of the sealing member 3 to make the sealing member 3 tightly hold the liquid cooling pipe 1. The tightening hoop is a strip-shaped member provided with a ratchet structure along the length direction, which can surround the connecting portion 7 of the sealing member 3 and tighten the connecting portion 7 and the liquid cooling pipe 1 through the ratchet structure.

[0057] Further, the utility model discloses a liquid cooling converter, it includes liquid cooling cabinet, converter and liquid cooling assembly, converter and liquid cooling assembly are installed in liquid cooling cabinet, liquid cooling assembly is transported cooling liquid through liquid cooling pipeline 1 and is used to heat dissipation for converter, liquid cooling cabinet is equipped with the sealing plate 2 for separating and forms chamber, and the sealing structure for liquid cooling pipeline in liquid cooling cabinet as described above is used to realize the sealed connection between liquid cooling pipeline 1 and sealing plate 2.

[0058] Regarding how the liquid cooling converter realizes the sealed connection between the liquid cooling pipeline 1 and the sealing plate 2 by using the sealing structure described above, reference is made to the description of the sealing structure for the liquid cooling pipeline in the liquid cooling cabinet of the utility model above. Regarding other parts of the liquid cooling converter, they are well known in the art and will not be described here in detail.

[0059] The above description and the embodiments are used to explain the scope of protection of the utility model, but do not constitute the limitation of the scope of protection of the utility model. Through the inspiration of the utility model or the above-mentioned embodiments, the modification, equivalent replacement or other improvement of the utility model embodiments or one part of the technical features can be obtained by the ordinary skilled in the art combining with the common knowledge, the ordinary technical knowledge of the art and / or the prior art through the logical analysis, reasoning or limited test, and should be included in the protection scope of the utility model.
