Description

[0001] The present invention relates to the technical field of liquid cooling systems, and in particular to a liquid cooling connection device. Background Art

[0002] Liquid-cooled connectors are widely used in various fields, especially in the new energy vehicle industry and energy storage equipment, where liquid-cooled connectors are extremely important components.

[0003] In servers using liquid-cooled connectors, most of the current liquid-cooled connectors have external supporting parts that occupy a large area, and the male head in the connector can only achieve one-way reciprocating movement. When the installation space in the server using the liquid-cooled connector is limited, it is not convenient to install the pipeline for transporting liquid. At the same time, the female head generally needs to be pre-fixed in the server. In a server, multiple female heads are fixed. When multiple male heads are required to be connected and matched with multiple female heads, the multiple male heads mostly need to be fixed together side by side to match the multiple female heads. The hard connection causes the supporting part carrying the male head to be pushed in, and there will be position tolerances in the front, back, left, right, up and down directions, making it inconvenient to connect multiple male heads and female heads. Then, they cannot be inserted by force, or they cannot be fully inserted, affecting the installation efficiency and normal use. Summary of the Invention

[0004] The purpose of the present invention is to provide a liquid cooling connection device to form a flexible connection between the carrier and the male head, reduce the inconvenience of connecting the liquid delivery pipeline due to the small internal space of the server where the liquid cooling connection device is installed, and at the same time absorb position tolerances so that multiple male heads and multiple female heads that are fixed side by side can be installed in conjunction with each other.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work shall fall within the scope of protection of the present invention.

[0028] Please refer to Figures 1 and 2 , the present invention provides a technical solution: a liquid cooling connection device, including a carrier, a male connector 1, a female connector 2, a reset member, and a locking member;

[0029] The carrier is a hollow shell structure, and the carrier is sleeved on the outside of the male head 1, and the outer surface of the male head 1 is spaced apart from the inner wall of the carrier;

[0030] Both ends of the male connector 1 pass through the carrier. The outer surface of the male connector 1 located inside the carrier is fixedly connected to a limit ring 4. An avoidance groove 5 is provided on the inner wall of the carrier. The bottom of the avoidance groove 5 is spaced apart from the limit ring 4. The length of the avoidance groove 5 is greater than the thickness of the limit ring 4.

[0031] One end of the male connector 1 is threadedly connected to the female connector 2 via a threaded groove. A flow cavity 3 is defined at the bottom of the threaded groove. The female connector 2 is at least partially located within the flow cavity 3, and the outer surface of the female connector 2 located within the flow cavity 3 is in contact with the inner wall of the flow cavity 3.

[0032] The locking member is detachably connected to the end of the carrier away from the female connector 2 and is at least partially located within the carrier. The locking member is sleeved on the outside of the male connector 1 and the inner wall is spaced apart from the outer surface of the male connector 1. The end surface of the locking member located within the carrier is flush with the edge of the avoidance groove 5 away from the female connector 2 and is in contact with the surface of the limit ring 4.

[0033] The reset member is arranged in the carrier and is sleeved on the outside of the male head 1 and is spaced apart from the outer surface of the male head 1. The end surface of the reset member away from the female head 2 is in contact with the surface of the limit ring 4 away from the locking member, and is used to apply a force to push the limit ring 4 against the locking member.

[0034] Through the connection between the carrier and the male head 1, the male head 1 can be slidably installed in the carrier, and through the connection between the locking member and the limiting ring 4, the male head 1 can be tightly limited, so that the male head 1 cannot pass through the end of the carrier located at the locking member. Through the setting of the limiting ring 4, the male head 1 cannot pass through the end of the carrier away from the locking member. At the same time, with the avoidance groove 5, the male head 1 can be floated in the second direction. Through the setting of the reset member, after pressing the male head 1 to adjust the position to install the female head 2 or the conveying pipeline, continuously applying force to make the limiting ring 4 on the male head 1 press against the locking member, so as to avoid shaking during use and causing the pipeline connection to loosen;

[0035] By removing the locking member, the male head 1 can be removed from the carrier, and the reset member can also be removed from the carrier, which facilitates replacement and maintenance and reduces cost waste and loss.

[0036] In this embodiment, as a preferred solution, the reset member includes a transmission cylinder 6 and a reset spring 7 sleeved on the outside of the male head 1. The inner wall of the transmission cylinder 6 and the reset spring 7 are both spaced apart from the outer surface of the male head 1. One end of the transmission cylinder 6 is in contact with and connected to the surface of the limit ring 4 away from the locking member, and the other end of the transmission cylinder 6 abuts against one end of the reset spring 7. The other end of the reset spring 7 abuts against the bearing member. The length of the transmission cylinder 6 is greater than the length of the avoidance groove 5, and the outer surface of the transmission cylinder 6 slides in the bearing member along the first direction;

[0037] Through the connection between the transmission cylinder 6 and the limiting ring 4, the transmission cylinder 6 can receive the thrust generated by the reset spring 7, transmit it to the limiting ring 4, and push the limiting ring 4 to move toward the locking member. Through the connection between the transmission cylinder 6 and the male head 1, the male head 1 can swing in the transmission cylinder 6 or move along the second direction. Through the connection between the transmission cylinder 6 and the supporting member, the transmission cylinder 6 can move in the first direction in the supporting member but cannot move along the second direction.

[0038] In this embodiment, as a preferred solution, the carrier includes a carrier shell 8, one end of which is threadedly connected to the locking member via a threaded groove, and the locking member is at least partially located within the carrier shell 8. The avoidance groove 5 is formed on the inner wall of the carrier shell 8 and the edge away from the female connector 2 is flush with the end surface of the locking member located within the carrier shell 8.

[0039] The locking member can be installed or disassembled through the connection between the supporting shell 8 and the locking member. The end face of the locking member located in the supporting shell 8 is flush with the edge of the avoidance groove 5, so that the limit ring 4 cannot exceed the edge of the avoidance groove 5 close to the locking member, so that when it does not move in the first direction, it can move stably in the second direction, avoiding obstruction when it cannot move in the first direction and needs to move in the second direction.

[0040] In this embodiment, as a preferred solution, a positioning block 9 is fixedly connected to one end of the carrier shell 8 away from the locking member, and the inner wall of the positioning block 9 is spaced apart from the male connector 1 and the female connector 2 .

[0041] In this embodiment, as a preferred solution, the locking member includes a locking cover 10. The end surface of the locking cover 10 is sleeved on the outside of the male connector 1 through a through hole, and the outer surface is threadedly connected to the carrier shell 8 through a threaded connection. One end surface of the locking cover 10 is in contact with the limiting ring 4.

[0042] Through the connection between the locking cover 10 and the male connector 1 , the male connector 1 can float or swing along the second direction inside the locking cover 10 .

[0043] In this embodiment, as a preferred solution, a closing mechanism is further included, which includes a stopper 11, a blocking member, a limiter, and a support rod 12. The support rod 12 is disposed in the female connector 2. The stopper 11, the blocking member, and the limiter are sequentially disposed in the flow cavity 3 along the first direction. The surfaces of the stopper 11 and the limiter are provided with holes for liquid circulation. The blocking member is used to block the holes provided on the stopper 11 and the limiter. The limiter is slidably connected to the inner wall of the flow cavity 3.

[0044] The limiting member is provided with a first position and a second position. When the limiting member is in the first position, the limiting member is sleeved on the outside of the support rod 12 through the hole opened on the limiting member, and is spaced apart from the surface of the support rod 12. The support rod 12 supports the blocking member, and the liquid in the flow cavity 3 enters the female head 2. When the limiting member is in the second position, the end of the support rod 12 away from the female head 2 is spaced apart from the surface of the limiting member away from the blocking member, and the blocking member blocks the stopper 11 and the hole opened on the limiting member.

[0045] When the liquid passes through the stopper 11, the stopper blocks the liquid and the liquid cannot continue to move through the stopper 11. When the liquid passes through the stopper 11, the stopper can push the stopper to block the stopper 11. At the same time, the liquid that accidentally passes through the stopper 11 cannot continue to flow through the connection between the stopper and the stopper. When the stopper moves from the first position to the second position, the stopper 12 is connected to the stopper through the hole on the stopper to support the stopper. When the stopper is in the second position, the stopper also moves toward the stopper, thereby releasing the blockage of the stopper 11. At the same time, the stopper 12 supports the stopper, so that the stopper cannot block the stopper, and the liquid flows into the female head 2 through the stopper.

[0046] By setting the blocking piece, liquid can be prevented from accidentally entering the female head 2. When the liquid in the male head 1 needs to flow into the female head 2, the blocking limit of the blocking piece must be released first to play a protective role.

[0047] In this embodiment, as a preferred solution, the limiting member includes a blocking ring 13 and a limiting block 14. The surface of the blocking ring 13 is provided with a hole for liquid circulation, and the outer surface of the blocking ring 13 is provided with a groove. The blocking ring 13 is slidably connected to the limiting block 14 through the groove. The inner wall of the flow cavity 3 is provided with a limiting groove that cooperates with the limiting block 14.

[0048] Through the connection between the blocking ring 13 and the limit block 14, the limit block 14 can slide horizontally in the blocking ring 13. Through the cooperation between the limit block 14 and the limit groove opened on the inner wall of the circulation chamber 3, the connection between the blocking ring 13 and the circulation chamber 3 can be limited. When the connection limit between the blocking ring 13 and the circulation chamber 3 is released, the blocking ring 13 can move along the first direction in the circulation chamber 3 until the second position.

[0049] In this embodiment, as a preferred solution, a trigger member is also included, which includes a first magnet 15, a second magnet 16 and a third magnet 17. The first magnet 15 is fixedly connected to the surface of the limit block 14 facing the limit groove, and the second magnet 16 and the third magnet 17 are respectively arranged on the inner wall of the locking member. The magnetic poles of the second magnet 16 and the first magnet 15 are opposite, and the magnetic poles of the third magnet 17 and the first magnet 15 are the same. The blocking ring 13 can move along the first direction with the male head 1 through the limit block 14. Through the connection between the first magnet 15 and the second magnet 16, when the second magnet 16 is in contact with the male head 1, the blocking ring 13 can move along the first direction with the male head 1 through the limit block 14. When the positions of the first magnet 15 and the second magnet 16 correspond, the second magnet 16 uses magnetic force to suck the first magnet 15 and the limit block 14 out of the shielding ring 13, so as to limit the shielding ring 13. When the positions of the first magnet 15 and the third magnet 17 correspond, the third magnet 17 uses magnetic force to push the first magnet 15 and the limit block 14 into the shielding ring 13. When liquid flows into the shielding ring 13, the shielding ring 13 is subjected to the impact of the liquid and its own gravity, and can move to the second position, thereby releasing the blockage of the blockage member on the blocker 11 and the shielding ring 13, so as to allow the liquid to flow.

[0050] By setting the trigger member on the blocking ring 13, the opening or closing of the blocking member is achieved by cleverly combining the characteristic that the male head 1 can float along the first direction, while preventing the liquid from accidentally circulating in the male head 1 and the female head 2, the operation steps of the flow control valve are also reduced. Since the male head 1 and the female head 2 need to be connected first, and then the liquid is introduced after the connection, when the male head 1 and the female head 2 are connected, it is necessary to check again, which can prevent the liquid from accidentally directly passing through the male head 1 into the female head 2. When the liquid needs to flow into the female head 2 through the male head 1, the male head 1 is pressed to move the male head 1 along the first direction. After moving to the position of the third magnet 17, the liquid connection between the male head 1 and the female head 2 is achieved, which effectively plays a role in safety protection.

[0051] When the shielding ring 13 needs to be reset, the shielding ring 13 is moved to a position corresponding to the second magnet 16 , and the second magnet 16 sucks out the first magnet 15 together with the limiting block 14 to lock them.

[0052] In this embodiment, as a preferred solution, a tightening member is further included, which includes a tightening spring 18. The tightening spring 18 is arranged between the female head 2 and the shielding ring 13 and is sleeved on the outside of the support rod 12. One end of the tightening spring 18 abuts against the end surface of the female head 2 facing the shielding ring 13, and the other end of the tightening spring 18 abuts against the surface of the shielding ring 13 facing the female head 2;

[0053] By the action of the tensioning spring 18, the shielding ring 13 can be continuously applied with a force. After the liquid is stopped from being transported to the male head 1, the shielding ring 13 can be pushed to move from the second position to the first position. When the first magnet 15 and the second magnet 16 are moved to the corresponding position, the first magnet 15 is sucked out of the limit position. The elastic force of the tensioning spring 18 can overcome the gravity of the blocking piece and the shielding ring 13. At the same time, there is the repulsive force generated by the third magnet 17 on the first magnet 15 during resetting. When the liquid is transported to the male head 1, the liquid in the male head 1 reaches the stopper 11 and the blocking piece, and through the attraction between the first magnet 15 and the second magnet 16, the limit block 14 is cooperated. The connection between the limiting block 14 and the limiting groove can prevent the liquid pressure from being transmitted to the tightening spring 18. When the connection between the limiting block 14 and the limiting groove is released, the shielding ring can overcome the thrust of the tightening spring 18 through the punching of the liquid, so that the liquid enters the female head 2 from the male head 1. When the liquid supply is stopped, the tightening spring 18 pushes the shielding ring to reset. When the liquid is introduced into the male head 1 again, the liquid cannot directly enter the female head 2. It is necessary to press the male head 1 to move it in the first direction until the first magnet 15 corresponds to the position of the third magnet 17. This can avoid accidentally opening the wrong liquid input valve during the adjustment process and also prevent liquid leakage.

[0054] The blocking piece can prevent liquid leakage. After the male connector 1 and the female connector 2 are connected, if the blocking piece is not released, the liquid cannot enter the female connector 2 smoothly, thereby avoiding accidental leakage. This ensures that the liquid will not be wasted or cause environmental pollution during the connection process. After the blocking piece is released, the liquid can flow freely between the male connector 1 and the female connector 2, which is convenient for subsequent operations or transmission. When the output end of the female connector 2 needs to switch the receiving terminal or the output end of the female connector 2 is not connected, the liquid in the male connector 1 can be prevented from accidentally entering the female connector 2.

[0055] In this embodiment, as a preferred solution, the blocking member includes a blocking ball 19 , which is located between the stopper 11 and the blocking ring 13 .

[0056] Alternatively, the connection pipe for inputting liquid has been connected to the male connector 1 and the liquid has been delivered to the male connector 1 , and then the male connector 1 needs to be connected to the female connector 2 to prevent the liquid from flowing out of the male connector 1 .

[0057] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
