[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] In the description of this application, "several" means one or more, "more" means at least two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0033] It is understandable that, referring to Figure 3 and Figure 4 The top of the original sealing ring is arc-shaped. After being installed in the thermal pipe and used for a long time, the arc surface on the top will be deformed, and then it will age and crack. Therefore, the original sealing ring cannot meet the long life requirements.

[0034] Reference Figure 1 , Figure 2 and Figure 5 The sealing ring for a thermal pipe in the first aspect of the embodiment of the present application is specifically a rubber sealing ring for a thermal pipe, and the sealing ring for the thermal pipe includes a hard rubber elastomer 100 and a soft rubber elastomer 200.

[0035] One side of the soft rubber elastic body 200 is connected to the hard rubber elastic body 100, and the other opposite end of the soft rubber elastic body 200 is provided with a top structure 210, and the top structure 210 includes a top surface arranged in a conical shape. In some embodiments, the top surface is arranged as a conical surface, for details, refer to Figure 1 The conical surface has a first straight side 211 and a second straight side 212 in the cross section, and the first straight side 211 and the second straight side 212 are arranged at a preset angle so as to improve the performance of the soft rubber elastic body 200. It can be understood that the soft rubber elastic body 200 is a lemon-shaped structure, and the lemon-shaped soft rubber elastic body 200 and the wedge-shaped hard rubber elastic body 100 are combined into a sealing ring, and the top of the soft rubber elastic body 200 is set as a conical top structure 210 with two straight sides, so that it is less likely to have a fracturing phenomenon caused by aging than a sealing ring with a circular arc surface at the top.

[0036] In some embodiments, the sealing ring is a rubber sealing ring for a thermal pipe, and the soft elastomer 200 is in the shape of a lemon. One outer surface of the soft elastomer 200 is connected to the wedge-shaped hard elastomer 100, which improves the problem of aging and fracturing of the original rubber sealing ring for the thermal pipe while ensuring the sealing performance.

[0037] Reference Figure 1 , Figure 2 and Figure 5 The sealing ring for a thermal pipe in the first embodiment of the present application improves the structure of the soft rubber elastomer 200 so that its top structure 210 has a first straight edge 211 and a second straight edge 212 arranged in a cone shape. Without changing the groove size and material properties, this structure can achieve a small compression rate and a large sealing force compared with the circular structure, effectively improving the problem of rubber ring rupture caused by the high compression rate of the original circular structure, while ensuring the sealing performance and extending the sealing service life.

[0038] Reference Figure 1 and Figure 2In some embodiments of the present application, the soft gel elastomer 200 further includes an intermediate structure 220 and a bottom structure 230. The bottom surface of the bottom structure 230 is used to connect with the hard gel elastomer 100, and the intermediate structure 220 is respectively connected to the bottom structure 230 and the top structure 210. It can be understood that by specifically designing the soft gel elastomer 200 to have the shape of the bottom structure 230, the intermediate structure 220 and the top structure 210, it can not only adapt to the specific installation environment, improve the sealing degree, and improve the aging and fracturing problem, but also make the soft gel elastomer 200 reliably connected to the hard gel elastomer 100.

[0039] In some embodiments, the bottom structure 230, the middle structure 220 and the top structure 210 are an integrated structure, which is integrally formed by high temperature vulcanization. In other embodiments, the bottom structure 230, the middle structure 220 and the top structure 210 are formed according to the structural design respectively, and then connected in sequence, wherein the connection method can be carried out according to the conventional connection method of rubber.

[0040] Reference Figure 1 and Figure 2 In some embodiments of the present application, the middle structure 220 includes vertical edges 221 on both sides, and the middle structure 220 is connected to the bottom structure 230 and the top structure 210 respectively through the vertical edges 221. It can be understood that the thickness of the middle part can be determined according to the size of the installation part, wherein the shape of the middle structure 220 on the cross section is designed to have a regular shape with vertical edges 221 on both sides, so as to play a good compression sealing role and achieve a small compression rate and a large sealing force.

[0041] In some embodiments, the cross-sectional shape of the intermediate structure 220 is set to be square. In other embodiments, the two sides of the intermediate structure 220 can also be designed to include but not limited to beveled edges, curved edges, etc., so as to meet different usage requirements.

[0042] In some embodiments of the present application, the soft rubber elastic body 200 includes a rounded transition structure 240, and the top of each vertical edge 221 is connected to the top structure 210 through the rounded transition structure 240. It can be understood that the rounded transition between the intermediate structure 220 and the top structure 210 can ensure the smoothness of the overall structure, and ensure that the top structure 210 can effectively improve the problem of rubber ring rupture caused by the high compression rate of the original circular structure, while the intermediate structure 220 can achieve a small compression rate and a large sealing force.

[0043] In some embodiments of the present application, the middle structure 220 includes first curved surfaces 222 located on both sides, and the bottom structure 230 is transitionally connected to the vertical edge 221 through the first curved surfaces 222. In some embodiments of the present application, the bottom structure 230 includes second curved surfaces 231 located on both sides of the bottom surface, and the bottom structure 230 is transitionally connected to the hard rubber elastomer 100 through the second curved surfaces 231. It can be understood that by setting the first curved surface 222 and the second curved surface 231, the overall shape of the soft rubber elastomer 200 is lemon-shaped. On the basis of not changing the groove size and material properties, this structure can achieve a small compression rate and a large sealing force compared with the circular structure, and effectively improves the problem of rubber ring rupture caused by the large compression rate of the original circular structure.

[0044] In some embodiments, the curvature and length of the first arc surface 222 and the second arc surface 231 can be specifically designed according to actual conditions, thereby ensuring that the overall structure of the soft rubber elastomer 200 is reasonable, while the hard rubber elastomer 100 and the soft rubber elastomer 200 can be smoothly connected, and the overall performance of the sealing ring is better.

[0045] In some embodiments of the present application, the compression rate of the middle structure 220 is between 13% and 35%. It is understood that the thickness of the middle part can be determined according to the size of the installation part, and the compression rate can be between 13% and 35% to meet the use requirements.

[0046] Reference Figure 1 and Figure 2 In some embodiments of the present application, the top angle of the top surface is set at an angle of 90° to 150°. In some embodiments, the top surface has a first straight edge 211 and a second straight edge 212 in the cross section, and the first straight edge 211 and the second straight edge 212 are set at an angle of 90° to 150°. It can be understood that by limiting the angle between the first straight edge 211 and the second straight edge 212, the use requirements are met, and the problem of aging and fracturing of the original rubber sealing ring for thermal pipes is further improved.

[0047] Reference Figure 1 and Figure 2 In some embodiments of the present application, the hard rubber elastomer 100 and the soft rubber elastomer 200 are made by high temperature vulcanization molding. It can be understood that the preparation process of the rubber sealing ring for the thermal pipe includes the following steps:

[0048] Step 1, preforming the hard rubber part by pressurization;

[0049] Step 2: The soft rubber part and the hard rubber part are vulcanized and formed together at high temperature.

[0050] It is understandable that the lemon-shaped soft rubber elastomer 200 can achieve a small compression rate and a large sealing force, effectively improving the problem of rubber ring rupture caused by the large compression rate of the original circular structure. In some embodiments, the material selection and hard-soft adjustment limit of the hard rubber part and the soft rubber part are conventional technical means. This application only makes improvements in structure, so the materials of the soft rubber and the hard rubber are not further described here.

[0051] In some embodiments, specific reference is made to Figure 2 , a avoidance opening for matching the thermal pipe is provided on the hard rubber elastic body 100. In other embodiments, other structural shapes can be provided on the hard rubber elastic body 100 to adapt to the thermal pipe installation requirements in different scenarios.

[0052] Reference Figure 1 , Figure 2 and Figure 5 The thermal pipe of the second aspect embodiment of the present application can be an assembled pipe, having an insertion end and a receiving end connected to the insertion end. The thermal pipe includes a sealing ring for the thermal pipe of the first aspect embodiment of the present application. The sealing ring is used for the assembly of the insertion end and the receiving end. On the basis of not changing the groove size and material properties, the improved lemon-shaped soft rubber elastomer 200 can achieve a small compression rate and a large sealing force. While ensuring the sealing performance, it can improve the aging and fracturing problem of the original rubber sealing ring for the thermal pipe and extend the service life of the seal.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0054] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
