DETAILED DESCRIPTION

[0059] In order to make the technical problems solved by the present disclosure, the technical solutions adopted and the technical effects reached more clear, the technical solutions of the present disclosure will be further described below in combination with the drawings and through specific embodiments.

[0060] In the description of the present disclosure, unless explicitly defined and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0061] In the present disclosure, unless explicitly defined and limited, the first feature "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0062] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0063] In existing technologies, male or female connectors are fixed to the inlet and outlet by welding. Due to low welding precision and the existence of welding tolerances, when the inlet and outlet pipes are subsequently connected to the inlet and outlet, the male or female connectors welded to the inlet and outlet are not on the same plane as the female or male connectors on the inlet and outlet pipes. This prevents the female and male connectors from aligning properly, thus preventing the liquid cooling plate from being properly assembled with the inlet and outlet pipes. The male connector must be re-welded to achieve proper assembly. Furthermore, because the male and female connectors fixed to the inlet and outlet cannot be moved, their deformation allowance is small. If deformation or twisting occurs during subsequent assembly or use, the male or female connectors on the liquid cooling plate are prone to damage or breakage, increasing the risk of cooling medium leakage.

[0064] Example 1

[0065] This embodiment provides an adapter 1000, such as Figures 1-6 As shown, the adapter 1000 includes a swing connector and a body 200 connected in sequence and in communication with each other. The swing connector includes a first adapter part 100 and / or a second adapter part 300, and the sum of the number of the first adapter part 100 and the second adapter part 300 is greater than or equal to one. The free end of the first adapter part 100 is in communication with the liquid inlet or liquid outlet on the liquid cooling plate, and the free end of the second adapter part 300 is in communication with the connector on the liquid inlet pipe or liquid outlet pipe. The first adapter part 100 can swing arbitrarily within a preset angle range relative to the axial direction T1 of the body 200, and the second adapter part 300 can swing arbitrarily within a preset angle range relative to the axial direction T1 of the body 200.

[0066] The adapter 1000 realizes the effect that the cooling liquid in the liquid inlet pipeline flows into the liquid cooling plate along the adapter 1000 or the cooling liquid in the liquid cooling plate flows into the liquid outlet pipeline along the adapter 1000 by connecting the free end of the first adapter 100 with the liquid inlet or the liquid outlet on the liquid cooling plate and connecting the free end of the second adapter 300 with the liquid inlet pipeline or the liquid outlet pipeline, and by enabling the first adapter 100 to swing at any angle within a preset angle range relative to the axial direction T1 of the body 200 and enabling the second adapter 300 to swing at any angle within a preset angle range relative to the axial direction T1 of the body 200, the relative positions of the adapter 1000, the liquid inlet pipeline and the liquid inlet and the relative positions of the adapter 1000, the liquid outlet pipeline and the liquid outlet in space can be adjusted according to actual needs, the liquid inlet pipeline and the liquid inlet or the liquid outlet pipeline and the liquid outlet are conveniently connected, the connection requirements of the liquid inlet and the liquid inlet pipeline and the liquid outlet and the liquid outlet pipeline are met, and the assembly applicability and the assembly efficiency are improved.

[0067] It should be noted that in the present embodiment, the sum of the number of the first adapter 100 and the second adapter 300 is two, that is, the adapter 1000 in the present embodiment includes the first adapter 100 connected with one end of the body 200 and the second adapter 300 connected with the other end of the body 200. Moreover, the first adapter 100 and the second adapter 300 can both be male connectors or female connectors. If the first adapter 100 is a male connector, the liquid inlet or the liquid outlet connected with the first adapter 100 needs to be provided with a female connector, and if the first adapter 100 is a female connector, the liquid inlet or the liquid outlet connected with the first adapter 100 needs to be provided with a male connector. If the second adapter 300 is a male connector, the liquid inlet pipeline or the liquid outlet pipeline connected with the second adapter 300 needs to be provided with a female connector. If the second adapter 300 is a female connector, the liquid inlet pipeline or the liquid outlet pipeline connected with the second adapter 300 needs to be provided with a male connector.

[0068] Specifically, the preset angle is an acute angle, so that the second adapter 300 can adjust the swing angle relative to the axis of the first adapter 100 within a range of 180°, meeting the actual installation requirements of the liquid inlet pipe and the liquid inlet, and the liquid outlet pipe and the liquid outlet. It should be noted that in the actual installation operation, it is only necessary to ensure that the second adapter 300 can adjust the swing angle relative to the axis of the first adapter 100 within a range of 90° to meet various requirements, so in the present embodiment, the preset angle is 45°, so the second adapter 300 can be arbitrarily rotated with the axis of the first adapter 100 as the rotation axis while being arbitrarily swung within a range of 90° relative to the axis of the first adapter 100. In other embodiments, the specific value of the preset angle can also be adjusted within a range of 0°-90° according to actual requirements, and the present embodiment does not make specific limitations.

[0069] In addition, to further improve the communication efficiency of the adapter 1000 to the liquid inlet pipe and the liquid inlet, and the communication efficiency to the liquid outlet pipe and the liquid outlet, the first adapter 100 can rotate around the axial direction T1 of the body 200, and the second adapter 300 can rotate around the axial direction T2 of the body 200. By enabling the first adapter 100 to rotate around the axial direction T1 of the body 200, and the second adapter 300 to rotate around the axial direction T2 of the body 200, when it is necessary to use the adapter 1000 to communicate the liquid inlet with the liquid inlet pipe or to communicate the liquid outlet with the liquid outlet pipe, the angle adjustment efficiency of the first adapter 100 and the second adapter 300 can be further improved, and the subsequent communication efficiency of the liquid inlet pipe and the liquid inlet, and the communication efficiency of the liquid outlet pipe and the liquid outlet can be further improved.

[0070] In the present embodiment, in order to realize the swing and rotation of the first adapter 100 relative to the body 200, as shown in FIG. 1, the first adapter 100 is provided with a first rotating portion 110 and a second rotating portion 120, and the second adapter 300 is provided with a third rotating portion 310 and a fourth rotating portion 320. Figures 4-9As shown, the first adapter 100 is provided with a first annular protrusion 110, which is circumferentially arranged around the outer peripheral wall of the end of the first adapter 100 connected to the body 200. The inner wall of the end of the body 200 connected to the first adapter 100 is provided with a first counter-slot 210, which is circumferentially arranged around the inner wall of the body 200. The two contact surfaces of the first counter-slot 210 opposite to the first annular protrusion 110 are in profile sliding fit. The profile arc length L1 of the first contact surface S1 of the first annular protrusion 110 adapted to the first counter-slot 210 along the axial direction T2 of the first adapter 100 is greater than the profile arc length L2 of the second contact surface S2 of the first counter-slot 210 adapted to the first annular protrusion 110 along the axial direction T1 of the body 200. By arranging the first annular protrusion 110 on the first adapter 100, the first annular protrusion 110 is circumferentially arranged around the outer peripheral wall of the end of the first adapter 100 connected to the body 200, and the first counter-slot 210 in profile sliding fit with the first annular protrusion 110 is arranged on the inner wall of the end of the body 200 connected to the first adapter 100. The profile arc length L1 of the first contact surface S1 of the first annular protrusion 110 along the axial direction T2 of the first annular protrusion 110 is greater than the profile arc length L2 of the second contact surface S2 of the first counter-slot 210 along the axial direction T1 of the body 200, so that the first annular protrusion 110 can rotate around the axial direction T1 of the body 200 and deflect and slide relative to the axial direction T1 of the body 200. It should be noted that the contact surfaces of the first counter-slot 210 opposite to the first annular protrusion 110 are in profile sliding fit, which means that the groove surface of the first counter-slot 210 is the same as or similar to the convex surface of the first annular protrusion 110, so that the first counter-slot 210 can slide along the groove surface relative to the convex surface of the first annular protrusion 110, or the first annular protrusion 110 can slide along the convex surface along the groove surface of the first counter-slot 210.

[0071] Similarly, as Figure 6 、 Figure 10 and Figure 11As shown, the second adapter 300 is provided with a second annular protrusion 310, which is circumferentially arranged around the outer peripheral wall of one end of the second adapter 300 connected to the body 200. The inner wall of the one end of the body 200 connected to the second adapter 300 is provided with a second mating groove 220, which is circumferentially arranged around the inner wall of the body 200. The contact surface of the second mating groove 220 opposite to the second annular protrusion 310 is adaptively profiled and slid, and the third contact surface S3 of the second annular protrusion 310 for adapting the second mating groove 220 has a cross-sectional arc length L3 along the axial direction T3 of the second adapter 300 greater than the fourth contact surface S4 of the second mating groove 220 for adapting the second annular protrusion 310, which has a cross-sectional arc length L4 along the axial direction T1 of the body 200. This can realize the effect of rotating the second annular protrusion 310 around the axial direction T1 of the body 200 and deflecting and sliding the second annular protrusion 310 relative to the axial direction T1 of the body 200.

[0072] It should be noted that in the present embodiment, the first annular protrusion 110 and the second annular protrusion 310 are both C-shaped protrusions, and the first mating groove 210 and the second mating groove 220 are both C-shaped grooves adapted to the C-shaped protrusions, i.e., the first contact surface S1 and the third contact surface S3 are both C-shaped convex surfaces, and the second contact surface S2 and the fourth contact surface S4 are both C-shaped concave surfaces adaptively profiled and slid. In addition, the surface area of the C-shaped convex surface is greater than the surface area of the C-shaped concave surface, so as to ensure that the cross-sectional arc length L1 of the first contact surface S1 is greater than the cross-sectional arc length L2 of the second contact surface S2, and the cross-sectional arc length L3 of the third contact surface S3 is greater than the cross-sectional arc length L4 of the fourth contact surface S4, so that the C-shaped protrusion can rotate along the C-shaped groove while swinging relative to the C-shaped groove.

[0073] In addition, as shown in Figure 5 Since the first mating groove 210 is arranged on the body 200, the radial end surface P1 of the body 200 is formed with a first avoiding inclined surface 230 at an inclined angle α deviating from the axial direction T1 thereof. When the first annular protrusion 110 swings relative to the first mating groove 210, the first avoiding inclined surface 230 can provide a avoiding space for the swing of the first adapter 100 relative to the body 200, so as to avoid interference between the radial end surface P1 of the body 200 and the first adapter 100 during the swing.

[0074] In the embodiment, the other radial end surface P2 of the body 200 is formed with a second escape slope 240 at another set angle β deviated from the axial direction T1 of the body 200, and the angle α is the same as the angle β, and the first escape slope 230 and the second escape slope 240 are centrally symmetric with respect to the radial center line T of the body 200. When the second annular protrusion 310 swings relative to the second abutting groove 220, the second escape slope 240 can provide an escape space for the swing of the second adapter 300 relative to the body 200, so as to avoid interference between the radial end surface of the body 200 and the second adapter 300 during the swing. Of course, in other specific embodiments of the present disclosure, the angle α can also be different from the angle β; or not centrally symmetric with respect to the radial center line T of the body 200, for example, the plane where the second escape slope 240 is located can be parallel to the plane where the first escape slope 230 is located, or there is an included angle, which can be adjusted according to actual needs.

[0075] It should be noted that, as shown in Figure 7 , the first annular protrusion 110 and the second annular protrusion 310 are both obtained by rotating around the rotation axis thereof. The axial direction T4 of the first annular protrusion 110 is perpendicular to the plane S6 where the first escape slope 230 is located, and the axial direction T4 of the second annular protrusion 310 is perpendicular to the plane S8 where the second escape slope 240 is located.

[0076] In addition, during the swing of the first adapter 100 relative to the body 200 and during the swing of the second adapter 300 relative to the body 200, the conductive area of the first adapter 100 and the conductive area of the second adapter 300 do not change, and the cross-sectional area of the cooling liquid flowing through the first adapter 100, the body 200 and the second adapter 300 remains unchanged, which can further ensure the flow rate of the cooling liquid.

[0077] As an optional solution, the adapter 1000 further comprises a sealing member 400, wherein the first adapter 100 and the second adapter 300 respectively extend into the two ends of the body 200, and the body 200 is provided with a mounting groove on at least one of the two opposite contact surfaces inside the first adapter 100, and the mounting groove is used for accommodating the sealing member 400, and the body 200 is provided with a mounting groove on at least one of the two opposite contact surfaces inside the second adapter 300, and the mounting groove is used for accommodating the sealing member 400.

[0078] As shown in Figure 18 , Figure 19As shown, by compressing and clamping the sealing member 400 between the two contact surfaces of the first adapter 100 opposite to the body 200, the sealed butt joint between the first adapter 100 and the body 200 can be achieved, preventing the cooling liquid from leaking along the gap between the first adapter 100 and the body 200. By compressing and clamping the sealing member 400 between the two contact surfaces of the second adapter 300 opposite to the body 200, the sealed butt joint between the second adapter 300 and the body 200 can be achieved, preventing the cooling liquid from leaking along the gap between the second adapter 300 and the body 200.

[0079] It should be noted that the mounting groove can be the first mounting groove 250 or the second mounting groove 260. Specifically, in the embodiment, as shown in Figure 5 、 Figure 7 and Figure 8 , in order to ensure the sealing effect between the first contact surface S1 and the second contact surface S2, and to ensure the sealing effect between the third contact surface S3 and the fourth contact surface S4, the first mounting groove 250 is arranged on the second contact surface S2 in the first butt joint groove 210, and the second mounting groove 260 is arranged on the fourth contact surface S4 in the second butt joint groove 220, and the first mounting groove 250 and the second mounting groove 260 are respectively used to accommodate the sealing member 400. In other embodiments, only the sealing member 400 can be compressed and clamped between the first annular protrusion 110 and the first butt joint groove 210, and the first mounting groove 250 can be arranged on the second contact surface S2, or only the sealing member 400 can be compressed and clamped between the second annular protrusion 310 and the second butt joint groove 220, and the second mounting groove 260 can be arranged on the fourth contact surface S4 in the second butt joint groove 220, and the embodiment is not limited specifically.

[0080] In addition, as shown in Figure 7 , in the embodiment, the plane S5 where the groove wall of the first mounting groove 250 is located is parallel to the plane S6 where the first avoiding bevel 230 is located, and the axial direction T4 of the first annular protrusion 110 is perpendicular to the plane S5 where the groove wall of the second mounting groove 260 is located and the plane S6 where the first avoiding bevel 230 is located. The plane S7 where the groove wall of the second mounting groove 260 is located is parallel to the plane S8 where the second avoiding bevel 240 is located, and the axial direction T5 of the second annular protrusion 310 is perpendicular to the plane S7 where the groove wall of the second mounting groove 260 is located and the plane S8 where the second avoiding bevel 240 is located, so as to stably accommodate and fix the sealing member 400.

[0081] Specifically, in this embodiment, the sealing element 400 is an O-ring.

The O-ring is made of rubber. Rubber has good elasticity, toughness, and wear resistance, resulting in a long service life. In other embodiments, the O-ring can also be made of other elastic materials; this embodiment does not specifically limit this.

[0082] Example 2

[0083] This embodiment provides an adapter 1000. The specific structure of the adapter 1000 provided in this embodiment is basically the same as that in Embodiment 1. The difference between the specific structure of the adapter 1000 provided in this embodiment and that in Embodiment 1 is the specific structure of the sealing element 400.

[0084] like Figure 12 As shown, in this embodiment, the sealing element 400 has a cylindrical structure. Two sealing elements 400 are provided inside the adapter 1000. The sealing element 400 is sleeved on the outer peripheral wall of the mating end where the first adapter 100 is connected to the body 200, or sleeved on the outer peripheral wall of the mating end where the body 200 is connected to the second adapter 300, so that the sealing element 400 is disposed between the first adapter 100 and the body 200 or between the second adapter 300 and the body 200, so as to achieve the effect of sealing the first adapter 100 and the body 200 and sealing the second adapter 300 and the body 200 respectively.

[0085] Specifically, sealing elements 400 are respectively fitted between the first transition portion 100 and the main body 200, and between the second transition portion 300 and the main body 200. One sealing element 400 has its axial ends sealing the outer peripheral walls of the first transition portion 100 and the main body 200, respectively, while the other sealing element 400 has its axial ends sealing the outer peripheral walls of the second transition portion 300 and the main body 200, respectively. By using the cylindrical sealing elements 400 to seal the connection between the first transition portion 100 and the main body 200, and the connection between the second transition portion 300 and the main body 200, effective sealing of the first transition portion 100, the main body 200, and the second transition portion 300 can be achieved.

[0086] To ensure the rotation and swing of the first adapter 100 relative to the body 200 and the rotation and swing of the second adapter 300 relative to the body 200, the seal 400 has a certain elasticity, so that when the first adapter 100 or the second adapter 300 rotates and swings relative to the body 200, the first adapter 100 or the second adapter 300 can drive the corresponding seal 400 to deform, thereby avoiding interference between the first adapter 100 and the seal 400 or interference between the second adapter 300 and the seal 400, and ensuring the normal rotation and swing of the first adapter 100 and the second adapter 300.

[0087] It should be noted that the seal 400 can be an elastic plastic tube, one plastic tube is sleeved on the outer periphery of the connection between the first adapter 100 and the body 200, and the two ends of the plastic tube are respectively fixed with the outer peripheral wall of the first adapter 100 and the outer peripheral wall of the body 200 by using sealant bonding, and the other plastic tube is sleeved on the outer periphery of the second adapter 300 and the body 200, and the two ends of the plastic tube are respectively fixed with the outer peripheral wall of the second adapter 300 and the outer peripheral wall of the body 200 by using sealant bonding. In other embodiments, the seal 400 can also be a bellows or other cylindrical structure, as long as it can ensure its sealing effect and has a certain elasticity, and the specific structure of the embodiment is not limited.

[0088] Embodiment Three

[0089] The present embodiment provides an adapter 1000. The specific structure of the adapter 1000 provided by the present embodiment is basically the same as that of embodiment two, and the difference between the specific structure of the adapter 1000 provided by the present embodiment and that of embodiment two is that the specific structure of the seal 400 is different.

[0090] Specifically, as shown in Figure 13 The seal 400 is sleeved on the outer periphery of the first adapter 100, the body 200 and the second adapter 300 connected in sequence, and the axial ends of the seal 400 are respectively sealed with the outer peripheral wall of the first adapter 100 and the outer peripheral wall of the second adapter 300. By sleeving the seal 400 with a cylindrical structure on the outer periphery of the first adapter 100, the body 200 and the second adapter 300 assembled together, and making the two ends of the seal 400 respectively in sealing contact with the outer peripheral wall of the first adapter 100 and the outer peripheral wall of the second adapter 300.

[0091] Similarly, the sealing member 400 can be a plastic tube with elasticity, which is sleeved on the outer periphery of the first adapter 100, the body 200 and the second adapter 300, and the two ends of the plastic tube are fixed by sealing glue to the outer peripheral wall of the first adapter 100 and the outer peripheral wall of the second adapter 300, respectively.

The shape of the cross section of the δ-shaped sealing ring is approximately δ-shaped, which is equivalent to adding a ring-shaped extension 410 to the circumference of the outer edge of the O-shaped sealing ring. Taking the case that the upper end of the δ-shaped sealing ring is provided with the ring-shaped extension 410 as an example, the ring-shaped extension 410 protrudes from the first mounting groove 250 and the second mounting groove 260. When the first contact surface S1 on the first annular protrusion 110 is abutted with the second contact surface S2 of the first abutting groove 210, the first contact surface S1 on the first annular protrusion 110 is circumferentially attached to one side of the ring-shaped extension 410, the second contact surface S2 on the first mounting groove 250 is circumferentially attached to the other side of the ring-shaped extension 410, and the extension 410 on the corresponding sealing member 400 can be compressed to realize the sealed abutment of the first adapter 100 and the body 200. When the third contact surface S3 on the second annular protrusion 310 is abutted with the fourth contact surface S4 of the second abutting groove 220, the third contact surface S3 on the second annular protrusion 310 and the fourth contact surface S4 on the second mounting groove 260 can compress the extension 410 on the corresponding sealing member 400 to realize the sealed abutment of the second adapter 300 and the body 200. Moreover, the compression of the extension enables the extension and the main body of the δ-shaped sealing ring to be extruded together and form a reinforced structure, and the reinforced structure can improve the sealing effect.
