DETAILED DESCRIPTION

[0026] In order for those skilled in the art to better understand the scheme of the present application, the technical scheme in the specific embodiment of the present application will be described clearly and completely below in combination with the drawings in the embodiment of the present application.

[0027] As Figure 8 shown, in order to facilitate heat dissipation of the processor 6 of the data center, a liquid cooling device is usually installed on the processor 6 on the market at present, and the processor 6 is cooled by the liquid cooling device to prevent the processor 6 from being too high in temperature and affecting the operation efficiency of the processor 6. The liquid cooling device usually comprises a liquid cooling pipe 1 and a liquid cooling connector, and the liquid cooling connector is installed on the processor 6 so as to connect the liquid cooling pipe 1 to the processor 6, thereby cooling the processor 6 by the cooling liquid in the liquid cooling pipe 1.

[0028] As Figure 1 and Figure 2As shown, as an implementation manner, the application provides a liquid cooling connector for a data center liquid cooling device, the liquid cooling connector can be used for directly installing the liquid cooling pipe 1, without setting a plug at the end of the liquid cooling pipe 1, reducing the number of accessories of the liquid cooling pipe, reducing the cost of the liquid cooling pipe, and improving the assembly efficiency of the liquid cooling pipe.

[0029] The liquid cooling connector includes a connector body 2, a locking assembly 3, a moving limiting assembly 4 and a sealing assembly 5, the locking assembly 3, the moving limiting assembly 4 and the sealing assembly 5 are respectively installed in the connector body 2, wherein the sealing assembly 5 and the moving limiting assembly 4 can move along the axial direction of the connector body 2, and the locking assembly 3 can move along the radial direction of the connector body 2.

[0030] During the installation of the liquid cooling pipe 1, the liquid cooling pipe 1 is first inserted into the connector body 2, and the liquid cooling pipe 1 moves along the axial direction of the connector body 2, the liquid cooling pipe 1 is prevented from abutting against the locking assembly 3, the locking assembly 3 is driven to move along the radial direction of the connector body 2, with the movement of the locking assembly 3, the moving limiting assembly 4 is separated from the abutting surface of the locking assembly 3, under the action of the friction force, the sealing assembly 5 moves axially along with the liquid cooling pipe 1 until the sealing assembly 5 is locked with the locking assembly 3, and the end of the liquid cooling pipe 1 abuts against the connector body 2, completing the assembly of the liquid cooling pipe.

[0031] It should be noted that the sealing assembly 5 is at least partially a rubber part, so that when the liquid cooling pipe 1 is inserted into the sealing assembly 5, the sealing assembly 5 deforms, thereby ensuring the sealing between the sealing assembly 5 and the liquid cooling pipe 1, and at the same time, it can be ensured that the liquid cooling pipe 1 can drive the sealing assembly 5 to move towards the connector body 2.

[0032] As shown in Figure 2 and Figure 3 As an implementation manner, the connector body 2 is formed with a mounting cavity 2-1, a mechanism cavity 2-2 and a liquid passing channel 2-3, the mounting cavity 2-1 and the liquid passing channel 2-3 are arranged along the axial direction of the connector body 2, and the mounting cavity 2-1 and the liquid passing channel 2-3 are communicated, the mechanism cavity 2-2 is located in the mounting cavity 2-1, and the mechanism cavity 2-2 is communicated with the mounting cavity 2-1, and the mechanism cavity 2-2 is arranged along the radial direction of the connector body 2.

[0033] Further, an abutting surface 2-4 is formed between the mounting cavity 2-1 and the liquid passing channel 2-3, and the end surface of the liquid cooling pipe 1 abuts against the abutting surface 2-4 after the installation of the liquid cooling pipe 1 is completed.

[0034] It should be noted that the end surface of the liquid cooling pipe 1 or the abutting surface 2-4 is provided with a sealing ring, so as to ensure the sealing performance between the liquid cooling pipe 1 and the abutting surface 2-4 after the installation of the liquid cooling pipe 1 is completed.

[0035] As an implementation form, the plug-in interface 2-5 is formed in the liquid passage 2-3, and the abutting surface 2-4 is formed in the plug-in interface 2-5. After the liquid cooling pipe 1 is assembled, the liquid cooling pipe 1 is at least partially inserted into the plug-in interface 2-5.

[0036] Sealing rings are respectively installed on the inner wall of the plug-in interface 2-5 and the outer side wall of the liquid cooling pipe 1, so as to further improve the sealing performance of the connection between the liquid cooling pipe 1 and the plug-in interface 2-5.

[0037] As an implementation form, the end of the connector body 2 is formed with a recess 2-6, and a connecting groove 2-7 for installing the movement limiting assembly 4 is formed between the recess 2-6 and the installation cavity 2-1.

[0038] As an implementation form, the sealing assembly 5 is installed in the installation cavity 2-1, and the sealing assembly 5 can move along the axial direction of the connector body 2 relative to the connector body 2. By moving the sealing assembly 5 along the axial direction of the connector body 2, the sealing assembly 5 is connected with the locking assembly 3, so as to lock the sealing assembly 5 in the installation cavity 2-1.

[0039] The movement limiting assembly 4 is installed in the connecting groove 2-7 of the connector body 2, and the movement limiting assembly 4 can move along the axial direction of the connector body 2 relative to the connector body 2. When the movement limiting assembly 4 moves along the axial direction of the connector body 2, the sealing assembly 5 can move along the axial direction of the connector body 2.

[0040] As shown in Figure 2 and Figure 3 , the locking assembly 3 is installed in the installation cavity 2-1, and the locking assembly 3 can move along the radial direction of the connector body 2 relative to the connector body 2. By moving the locking assembly 3 along the connector body 2, the locking assembly 3 is dislocated with the movement limiting assembly 4, so that the movement limiting assembly 4 can move relative to the connector body 2 along the axial direction of the connector body 2, and the sealing assembly 5 can move along the axial direction of the connector body 2.

[0041] As an implementation form, the locking assembly 3 includes a locking block 3-3 and a reset spring 3-7. The locking block 3-3 is installed in the mechanism cavity 2-2, and the two ends of the reset spring 3-7 are respectively in abutment with the locking block 3-3 and the inner wall of the mechanism cavity 2-2, for providing an acting force of the locking block 3-3 towards the axial direction of the connector body 2.

[0042] As shown in Figure 4As shown, the locking block 3-3 is formed with a buckling groove 3-1 and a clutch groove 3-2, the buckling groove 3-1 is arranged towards the sealing assembly 5, and the sealing assembly 5 is locked in the mounting cavity 2-1 through the cooperation of the buckling groove 3-1 and the sealing assembly 5, and the clutch groove 3-2 is arranged towards the movement limiting assembly 4, and the movement limiting assembly 4 is moved along the axial direction through the cooperation of the clutch groove 3-2 and the movement limiting assembly 4, so as to facilitate the movement of the sealing assembly 5.

[0043] The sealing assembly 5 includes a sealing state connected with the buckling groove 3-1 and a to-be-assembled state separated from the buckling groove 3-1.

[0044] When the sealing assembly 5 is in the sealing state, the movement limiting assembly 4 is at least partially inserted into the clutch groove 3-2;

[0045] When the sealing assembly 5 is in the to-be-assembled state, the movement limiting assembly 4 is located outside the clutch groove 3-2, and the movement limiting assembly 4 abuts against the sealing assembly 5, so that the sealing assembly 5 cannot move along the axial direction under the limiting action of the movement limiting assembly 4, thereby facilitating the movement of the liquid cooling pipe 1 relative to the sealing assembly 5 towards the connector body 2.

[0046] It should be noted that the width of the clutch groove 3-2 is greater than the width of the movement limiting assembly 4, so as to prevent the movement limiting assembly 4 from interfering with the clutch groove 3-2 when the locking block 3-3 moves under the action of the sealing assembly 5, and to ensure the stability of the movement of the locking block 3-3.

[0047] As an implementation manner, the end face of the locking block 3-3 towards the sealing assembly 5 is formed with a first guide surface 3-4, a second guide surface 3-5 and an abutting surface 3-6, the first guide surface 3-4 and the second guide surface 3-5 are connected with the buckling groove 3-1 respectively, and the abutting surface 3-6 is located on the side of the first guide surface 3-4 away from the buckling groove 3-1.

[0048] Among them, the distance between the first guide surface 3-4 and the axis of the connector body 2 is less than the distance between the second guide surface and the axis of the connector body 2.

[0049] The first guide surface 3-4 is adapted to the liquid cooling pipe 1, and the locking block 3-3 is driven to move along the radial direction of the connector body 2 through the cooperation of the first guide surface 3-4 and the liquid cooling pipe 1.

[0050] The second guide surface 3-5 is adapted to the sealing assembly 5, and the locking block 3-3 is driven to move along the radial direction of the connector body 2 through the cooperation of the second guide surface 3-5 and the sealing assembly 5.

[0051] The abutting surface 3-6 is matched with the side wall of the liquid cooling pipe 1, and is arranged parallel to the side wall of the liquid cooling pipe 1. When the liquid cooling pipe 1 abuts against the abutting surface 3-6, the locking block 3-3 does not move when the liquid cooling pipe 1 moves relative to the locking block 3-3.

[0052] It should be noted that the first guide surface 3-4 and the second guide surface 3-5 are both inclined relative to the axis of the connector body 2, so as to facilitate the sealing assembly 5 and the liquid cooling pipe 1 to drive the locking block 3-3 to move.

[0053] The working steps of the locking block 3-3 are as follows:

[0054] When the liquid cooling pipe 1 is inserted into the sealing assembly 5, the two ends of the movement limiting assembly 4 abut against the locking block 3-3 and the sealing assembly 5 respectively, so that the position of the sealing assembly 5 is fixed, and the liquid cooling pipe 1 moves relative to the sealing assembly 5 and is inserted into the sealing assembly 5.

[0055] With the continuous insertion of the liquid cooling pipe 1, the liquid cooling pipe 1 abuts against the first guide surface 3-4, so that the locking block 3-3 moves along the radial direction of the connector body 2, until the side wall of the liquid cooling pipe 1 abuts against the abutting surface 3-6. At this time, the movement limiting assembly 4 is opposite to the clutch groove 3-2, and the movement limiting assembly 4 loses the supporting effect on the sealing assembly 5.

[0056] With the further insertion of the liquid cooling pipe 1, the sealing assembly 5 moves together with the liquid cooling pipe 1, and the sealing assembly 5 abuts against the second guide surface 3-5. The locking block 3-3 moves along the radial direction of the connector body 2, until the sealing assembly 5 is connected with the buckling groove 3-1, and the sealing assembly 5 is locked in the mounting cavity 2-1. In this process, the end of the liquid cooling pipe 1 is inserted into the insertion port 2-5, so as to ensure that the liquid cooling pipe 1 is sealingly connected with the connector body 2.

[0057] As shown in Figure 2 and Figure 3 , as an implementation manner, the movement limiting assembly 4 includes a limiting rod 4-1 and a reset spring 4-2. The limiting rod 4-1 is slidingly installed in the connecting groove 2-7 of the connector body 2, and the two ends of the limiting rod 4-1 abut against the sealing assembly 5 and the locking assembly 3 respectively. The reset spring 4-2 is connected with the limiting rod 4-1, and is used to provide an acting force on the limiting rod 4-1 away from the locking assembly 3. When it is needed to separate the liquid cooling pipe 1 from the liquid cooling connector, the limiting rod 4-1 is separated from the clutch groove 3-2, so as to facilitate the reset of the locking block 3-3.

[0058] As shown in Figure 5 , Figure 6 and Figure 7As shown, as an implementation manner, the sealing assembly 5 comprises a flexible sealing pad 5-1 and a support frame 5-2 fixed in the flexible sealing pad 5-1, the flexible sealing pad 5-1 is supported by the support frame 5-2, so as to prevent the sealing assembly 5 from being deformed excessively, so that the liquid cooling pipe 1 can be inserted into the sealing assembly 5.

[0059] The support frame 5-2 is formed with a first support part 5-3 and a second support part 5-4, the first support part 5-3 is located on the end surface of the sealing assembly 5 facing the locking assembly 3, the first support part 5-3 is adapted to the locking assembly 3, so as to lock the sealing assembly 5 and the locking assembly 3 by supporting and cooperating with the locking assembly 3; the second support part 5-4 is located on the end surface of the sealing assembly 5 away from the locking assembly 3, and the second support part 5-4 extends above the groove 2-6, so as to abut against the moving limiting assembly 4.

[0060] The outer edge of the first support part 5-3 is formed with a locking ring 5-5, the locking ring 5-5 is adapted to the buckling groove 3-1, that is, when the locking ring 5-5 moves into the buckling groove 3-1, the locking block 3-3 locks the support frame 5-2, so as to lock the sealing assembly 5 in the mounting cavity 2-1.

[0061] In order to separate the liquid cooling pipe 1 and the connector body 2, the locking ring 5-5 is formed with a notch 5-6, the width of the notch 5-6 is greater than or equal to the width of the buckling groove 3-1, by rotating the sealing assembly 5, the notch 5-6 is aligned with the locking block 3-3, so as to separate the locking ring 5-5 and the buckling groove 3-1, so as to facilitate the liquid cooling pipe 1 and the sealing assembly 5 to be pulled out from the mounting cavity 2-1 at the same time.

[0062] The flexible sealing pad 5-1 is made of rubber material, in order to improve the sealing performance between the flexible sealing pad 5-1, the liquid cooling pipe 1 and the inner wall of the mounting cavity 2-1, an arching piece 5-7 is connected to the middle part of the support frame 5-2, the arching piece 5-7 arches towards the inner wall of the mounting cavity 2-1.

[0063] By the action of the arching piece 5-7, the middle part of the flexible sealing pad 5-1 is deformed towards the liquid cooling pipe 1 and the mounting cavity 2-1 respectively, so as to increase the sealing performance of the device.

[0064] Finally, it should be noted that the above is only some preferred embodiments of the present application, and is not used to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to some technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
