Description

Technical Field

[0001] This utility model relates to the field of cooling components technology, and in particular to a leak-proof interface structure and external pipe interface for a water-cooled plate. Background Technology

[0002] A water-cooled plate, also known as a liquid-cooled plate, is a widely used heat dissipation component. It lowers the temperature of equipment by conducting heat through the flow of water. A water pump draws coolant from a tank, passes it over the heat-generating parts of the equipment, and absorbs heat through thermally conductive materials. The heat is then rapidly carried away by the flowing coolant. As the coolant reaches the water-cooled plate, its heat dissipation structure (such as heat sink fins) rapidly dissipates the heat into the external environment. Finally, the coolant returns to the tank and circulates, continuously reducing the equipment temperature.

[0003] After the coolant passes through the heat-generating parts of the equipment and enters the water-cooled plate, it is usually connected using fittings. For example, the "water-cooled plate sealing and leak-proof structure" proposed in Chinese Utility Model No. CN219555462U has an interface at the water inlet of the water-cooled plate, and the flow of coolant can be achieved by connecting the fitting to the interface. However, when water is used as the coolant and is continuously dissipating heat from high-temperature equipment, the temperature of the coolant rises significantly, which leads to high pressure in the water-cooled pipes, especially at the inlet of the water-cooled plate. Since the coolant has not yet been cooled by the water-cooled plate, the internal pressure here is high, and leakage is likely to occur at the inlet interface at high temperatures. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof structure for the interface of a water-cooled plate, comprising a first tubular connector disposed at the water inlet of the water-cooled plate, the first tubular connector having an inner circular tube surface that mates with an external connecting pipe, an annular limiting groove formed on the inner circular tube surface along a circular path, and a sealing element disposed on the annular limiting groove; the sealing element includes an elastic ring disposed on the annular limiting groove, the elastic ring being inserted into the annular limiting groove and forming an inner ring surface that extends beyond the opening of the annular limiting groove; wherein, a filling space is formed within the elastic ring, and the filling space is filled with a thermally responsive expansion agent.

[0006] As a further embodiment of this utility model: the filling space is an annular filling space arranged along the circumferential direction of the elastic ring.

[0007] As a further embodiment of this utility model: the annular limiting groove extends along the length direction of the first tubular connector; the elastic ring is correspondingly formed as an elastic tube extending along the length direction of the first tubular connector.

[0008] As a further embodiment of this utility model: multiple annular filling spaces are provided inside the elastic tube, and the multiple annular filling spaces are spaced apart along the length of the elastic tube.

[0009] As a further embodiment of this utility model: the inner tube surface of the elastic tube has an outwardly convex annular surface that corresponds one-to-one with the annular filling space.

[0010] As a further embodiment of this utility model: the first tubular connector also has an outer circular tube surface that mates with an external connecting tube, and an external thread is formed on the outer circular tube surface.

[0011] This utility model also provides the following technical solution: an external pipe interface, including a second tubular connector that is inserted into and cooperates with the inner circular tube surface of the first tubular connector. When the second tubular connector is inserted into the first tubular connector, the outer circular tube surface of the second tubular connector contacts the elastic ring that extends beyond the annular limiting groove.

[0012] As a further embodiment of this utility model: an annular limiting block is formed on the outer circular tube surface of the second tubular connector, which is arranged along a circular path on the outer circular tube surface. The annular limiting block abuts against the outer end face of the first tubular connector to form an insertion position.

[0013] As a further embodiment of this utility model: a sealing gasket is also provided on the second tubular connector, and when the second tubular connector is inserted into the first tubular connector, the sealing gasket is located between the annular limiting block and the outer end face of the first tubular connector.

[0014] As a further embodiment of this utility model: the outer circular tube surface of the first tubular connector is formed with an external thread; the second tubular connector is also fitted with a connecting sleeve, and when the second tubular connector is inserted into the first tubular connector, the annular limiting block is located between the connecting sleeve and the outer end face of the first tubular connector; the connecting sleeve is formed with a connecting cylinder extending towards the outer circular tube surface of the first tubular connector, and the inner side of the connecting cylinder is formed with an internal thread that mates with the external thread on the outer circular tube surface of the first tubular connector.

[0015] Compared with the prior art, the beneficial effects of this technical solution are as follows: When continuously dissipating heat from high-temperature equipment, the elastic ring is heated to a higher temperature, causing the thermally responsive expansion agent in the filling space to expand in volume, thereby causing the elastic ring to expand elastically and forming a further pressure seal on the external connecting pipe; that is, when the temperature of the coolant rises significantly, resulting in a higher pressure in the water-cooled pipe, the sealing effect provided by the interface anti-leakage structure of the water-cooled plate is correspondingly increased, making it less likely for leakage to occur at the inlet at high temperatures;

[0016] At normal temperatures, the temperature of the elastic ring drops to room temperature, and the thermally responsive expansion agent recovers its volume accordingly; under these conditions, the difficulty of plugging and unplugging the external connecting pipe will not increase.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[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] Please see Figure 1-4 A leak-proof structure for the interface of a water-cooled plate includes a first tubular connector 3 formed on the water inlet 2 of the water-cooled plate 1. The first tubular connector 3 has an inner circular tube surface that mates with an external connecting pipe. An annular limiting groove 4 is formed on the inner circular tube surface along a circular path. A sealing element is provided on the annular limiting groove 4.

[0027] The seal includes an elastic ring disposed on an annular limiting groove 4. The elastic ring is inserted into the annular limiting groove 4, and the inner ring surface of the elastic ring extends out of the groove opening of the annular limiting groove 4. A filling space is formed inside the elastic ring, and the filling space is filled with a thermally responsive expansion agent.

[0028] When continuously dissipating heat from high-temperature equipment, the elastic ring experiences a corresponding increase in temperature, causing the thermally responsive expansion agent within the filling space to expand in volume. This results in the elastic ring undergoing elastic expansion, thereby creating a further pressure seal on the externally connected pipe. In other words, when the coolant temperature rises significantly, leading to higher pressure within the water-cooled pipe, the sealing effect provided by the water-cooled plate's interface leak-proof structure increases accordingly, making it less likely for leaks to occur at the inlet at high temperatures.

[0029] At normal temperatures, the temperature of the elastic ring drops to room temperature, and the thermally responsive expansion agent recovers its volume accordingly; under these conditions, the difficulty of plugging and unplugging the external connecting pipe will not increase.

[0030] In some embodiments, the first tubular connector 3 is a first tubular connector with good thermal conductivity, such as a tubular connector formed on a copper water-cooling plate or an aluminum water-cooling plate.

[0031] In this embodiment, the filling space is an annular filling space 6 arranged along the circumferential direction of the elastic ring. When heated and expanded, it forms an overall expansion pressure, which is more conducive to improving the leak-proof effect.

[0032] In this embodiment, the annular limiting groove 4 extends along the length of the first tubular connector 3; the elastic ring is correspondingly formed as an elastic tube 5 extending along the length of the first tubular connector 3.

[0033] Preferably, the elastic tube 5 has a plurality of annular filling spaces 6, which are spaced apart along the length of the elastic tube 5. The inner surface of the elastic tube 5 has an outwardly convex annular surface 7 corresponding one-to-one with the annular filling spaces 6.

[0034] On the one hand, after thermal expansion, the inner surface of the elastic tube 5 forms multiple sealing rings through the convex annular surface; on the other hand, adjacent annular filling spaces share the same partition side 9, which is different from when the elastic ring is not extended. Figure 3 As shown, the partition side 9 can be subjected to the expansion pressure of the thermally responsive expansion agent in the two adjacent annular filling spaces when heated, making the elastic tube more susceptible to expansion and elastic expansion.

[0035] In some embodiments, the first tubular connector 3 further has an outer circular tube surface that mates with an external connecting tube, and an external thread 8 is formed on the outer circular tube surface.

[0036] In some embodiments, the elastic tube 5 is made of, for example, rubber material.

[0037] In some embodiments, the thermally responsive expansion agent used is air, which has a high coefficient of thermal expansion. Furthermore, by using air as the filler, the outer tube can elastically compress the elastic tube during insertion, allowing it to smoothly penetrate or pass through the elastic tube.

[0038] In this embodiment, an external pipe interface is also proposed for use in the interface leak-proof structure of the water-cooled plate. The external pipe interface includes a second tubular connector 100 that is inserted into the inner circular tube surface of the first tubular connector 3. When the second tubular connector 100 is inserted into the first tubular connector 3, the outer circular tube surface of the second tubular connector 100 contacts the elastic ring (elastic tube 5) that extends beyond the annular limiting groove 4.

[0039] The outer circular surface of the second tubular connector 100 is formed with an annular limiting block 200 arranged along a circular path on the outer circular surface of the tube. The annular limiting block 200 abuts against the outer end face of the first tubular connector 3 to form an insertion position.

[0040] A sealing gasket 300 is also fitted on the second tubular connector 100. When the second tubular connector 100 is inserted into the first tubular connector 3, the sealing gasket 300 is located between the annular limiting block 200 and the outer end face of the first tubular connector 3. That is, the annular limiting block 200 abuts against the outer end face of the first tubular connector 3 through the sealing gasket 300.

[0041] In some embodiments, the sealing gasket 300 is, for example, a rubber gasket.

[0042] In this embodiment, a connecting sleeve 400 is also slidably fitted onto the second tubular connector 100. When the second tubular connector 100 is inserted into the first tubular connector 3, the annular limiting block 200 is located between the connecting sleeve 400 and the outer end face of the first tubular connector 3. The annular limiting block 200 is configured to abut against the connecting sleeve 400, thereby restricting the connecting sleeve 400 from sliding further toward the outer end face of the first tubular connector.

[0043] The connecting sleeve 400 has a connecting cylinder 500 extending towards the outer circular tube surface of the first tubular connector 3. The inner side of the connecting cylinder 500 has an internal thread 600 that mates with the external thread 8 on the outer circular tube surface of the first tubular connector 3. By connecting the connecting pipe interface with the water-cooling plate through the interface anti-leakage structure, the anti-leakage effect at high temperatures is better while ensuring a stable connection.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
