Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Reference Figures 1 to 7 The present invention provides a rapid liquid cooling combination connector, including a male base unit 1, a female base unit 2, a male body 3, and a female body 4.

[0026] The male head base unit 1 has a male head spherical surface 13 inside, and the end of the male head body 3 has a male head mating spherical surface 311. The male head body 3 can form a mating contact with the male head spherical surface 13 through the male head mating spherical surface 311, so that the male head body 3 and the male head base unit 1 can form a movable connection. The male head body 3 can be deflected to a certain extent within the corresponding range of the male head spherical surface 13.

[0027] The female head base unit 2 is provided with a female head spherical surface 23 inside, and the end of the female head body 4 is provided with a female head mating spherical surface 411. The female head body 4 can form a mating contact with the female head spherical surface 23 through the female head mating spherical surface 411, so that the female head body 4 and the female head base unit 2 can form a movable connection. The female head body 4 can be deflected to a certain extent within the corresponding range of the female head spherical surface 23.

[0028] The quick liquid cooling combination connector can simultaneously achieve deflection angle and automatic centering. Specifically, the male connector body 3 can be inserted into the female connector body 4, and the two form a guiding structure and achieve automatic centering. At the same time, the male connector body 3 can deflect and move relative to the male connector spherical surface 13 and the female connector body 4 can deflect and move relative to the female connector spherical surface 23 to achieve angle deflection. After installation, the fluid channel can be opened, allowing the quick liquid cooling combination connector to be used in actual operation.

[0029] The quick-connect liquid-cooled combination connector integrates both deflection angle and automatic centering functions, making it easy to connect, disconnect, and reset, and reducing configuration costs compared to connectors with only a single function.

[0030] The quick liquid cooling combination connector is easier to use. It achieves automatic guidance and alignment through direct mating coupling of the male and female connectors, eliminating the need for additional guiding structures in the system and reducing the manufacturing cost of the liquid cooling system.

[0031] The quick liquid cooling combination connector has lower requirements for installation conditions and, thanks to its deflection angle, is more suitable for installation and connection in confined spaces. It also offers higher heat dissipation efficiency, effectively reduces noise, and enhances safety.

[0032] Rapid liquid cooling combination joints can be used in ultra-high voltage substations, wind power systems, high-power amplifier equipment cooling, electronic countermeasures equipment cooling, automotive engine cold testing, high-speed rail electrical cooling, machine tool hydraulic equipment, supercomputer cooling, new energy vehicles, tractors and other fields.

[0033] In this embodiment, the maximum deflection angle of the male head body 3 compared to the male head base unit 1, and the maximum deflection distance of the female head body 4 compared to the female head base unit 2, are preferably ±-5°, and the offset distance along the axis is preferably ±-4.5mm.

[0034] As an optional implementation, it also includes a male head first return spring 5, and a male head annular member 312 is provided on the outer wall of the male head body 3. The male head first return spring 5 is sleeved on the outside of the male head body 3 and its two ends are in contact with the male head base unit 1 and the male head annular member 312, respectively.

[0035] When the male head body 3 and the female head body 4 are in the plugged state, the first return spring 5 of the male head is squeezed by the male head body 3 which is in the deflection angle state, forming compression. When the male head body 3 and the female head body 4 are disconnected, the first return spring 5 of the male head is no longer squeezed, and at the same time, it recovers its deformation, driving the male head body 3 to reset until the male head body 3 returns to its initial state.

[0036] As an optional implementation, it also includes a first return spring 6 for the female head, and a female head annular member 412 is provided on the outer wall of the female head body 4. The first return spring 6 for the female head is sleeved on the outside of the female head body 4 and its two ends are in contact with the female head base unit 2 and the female head annular member 412, respectively.

[0037] When the male head body 3 and the female head body 4 are in the plugged state, the first return spring 6 of the female head is squeezed by the female head body 4 which is in the deflection angle state, forming compression. When the male head body 3 and the female head body 4 are disconnected, the first return spring 6 of the female head is no longer squeezed, and at the same time, it recovers its deformation, driving the female head body 4 to reset until the female head body 4 returns to its initial state.

[0038] As an optional implementation, at least one male spherical sealing groove 131 is provided on the male spherical surface 13. When there are multiple grooves, they are evenly distributed along the axial direction. In this embodiment, the structure with two male spherical sealing grooves 131 is preferably shown.

[0039] At least one female head spherical sealing groove 231 is provided on the female head spherical surface 23. When there are multiple grooves, they are evenly distributed along the axial direction. In this embodiment, the structure with two female head spherical sealing grooves 231 is preferably shown.

[0040] Each male spherical sealing groove 131 and each female spherical sealing groove 231 is provided with a first sealing ring 7, the inner side of the first sealing ring 7 can form contact with the male head mating spherical surface 311 or the female head mating spherical surface 411.

[0041] The first sealing ring 7 can play a sealing role between the male spherical surface 13 and the male mating spherical surface 311 and between the female spherical surface 23 and the female mating spherical surface 411. More importantly, the first sealing ring 7 can play a lubricating and buffering role, avoiding hard contact between them and causing wear, and effectively protecting the joint.

[0042] As an optional implementation method, the specific structural form of the male head base unit 1 has a wide range of options, and can be flexibly selected and set according to the actual needs of the user.

[0043] In the first form, the male head base unit 1 may consist of only a single male head base body 11, with a male head spherical surface 13 provided on the inner side of the male head base body 11.

[0044] In the second form, the male head base unit 1 includes a male head base body 11 and a male head base slide 12. The inner side of the male head base body 11 is provided with a male head annular cavity 111. The outer diameter of the male head base slide 12 is smaller than the inner diameter of the male head annular cavity 111, thereby providing a certain degree of movement space in the circumferential plane. The inner side of the male head base slide 12 is provided with a male head spherical surface 13. While the male head body 3 deflects and moves relative to the male head spherical surface 13, the male head base slide 12 can slide freely relative to the male head base body 11 in the circumferential plane of the male head annular cavity 111.

[0045] With this configuration, compared to the first type, the second type of male connector body 3, in addition to being able to deflect at an angle, can also move its axis radially relative to the male connector base slide 12 by following the synchronous movement of the male connector base slide 12, thereby further expanding its docking range and making it more suitable for installation and docking in more confined spaces.

[0046] As an optional implementation method, the specific structural form of the female head base unit 2 has a wide range of options, and can be flexibly selected and set according to the actual needs of the user.

[0047] In the first form, the female head base unit 2 may consist of only a single female head base body 21, with a female head spherical surface 23 provided on the inner side of the female head base body 21.

[0048] In the second form, the female head base unit 2 includes a female head base body 21 and a female head base slide 22. The inner side of the female head base body 21 is provided with a female head annular cavity 211. The outer diameter of the female head base slide 22 is smaller than the inner diameter of the female head annular cavity 211, thereby providing a certain degree of movement space in the circumferential plane. The inner side of the female head base slide 22 is provided with a female head spherical surface 23. While the female head body 4 deflects and moves relative to the female head spherical surface 23, the female head base slide 22 can slide freely relative to the female head base body 21 in the circumferential plane of the female head annular cavity 211.

[0049] With this configuration, compared to the first type, the second type of female head body 4, in addition to being able to deflect at an angle, can also move its axis radially relative to the female head base slide 22 by following the synchronous movement of the female head base slide 22, thereby further expanding its docking range and making it more suitable for installation and docking in more confined spaces.

[0050] As an optional implementation, the male connector body 3 includes a male connector housing 31, a male connector valve core 32, a male connector second return spring 33, a support base 34, and a double-ring clamp 35.

[0051] The end of the male connector housing 31 is provided with a male connector mating spherical surface 311, and the male connector valve core 32 is slidably connected inside the male connector housing 31.

[0052] The support base 34 is connected to the inside of the male head housing 31 by a double-ring clamp 35, and the support base 34 can provide support for the second return spring 33 of the male head.

[0053] The male valve core 33 is sleeved on the outside of the male valve core 32, and its two ends are in contact with the male valve core 32 and the support seat 34, respectively.

[0054] When the male valve core 32 is subjected to external force, it can apply pressure to the male second return spring 33, causing the male second return spring 33 to contract and store force. When the external force on the male valve core 32 is released, the male second return spring 33 returns to its deformation, driving the male valve core 32 to return to its original position.

[0055] As an optional implementation, the female head body 4 includes a female head housing 41, a female head valve spindle 42, a female head second return spring 43, and a sealing sleeve 44.

[0056] The end of the female head housing 41 is provided with a female head mating spherical surface 411, and the female head valve spindle 42 is connected inside the female head housing 41.

[0057] The sealing sleeve 44 is sleeved on the outside of the female valve spindle 42, and the second return spring 43 of the female valve is sleeved on the outside of the female valve spindle 42, with its two ends in contact with the sealing sleeve 44 and the female valve housing 41, respectively.

[0058] When the sealing sleeve 44 is subjected to external force, it can apply pressure to the second return spring 43 of the female head, causing the second return spring 43 of the female head to contract and store force. When the external force on the sealing sleeve 44 is released, the second return spring 43 of the female head restores its deformation and drives the sealing sleeve 44 to return to its original position.

[0059] In fact, during the insertion process of the male head body 3 and the female head body 4, the end face of the male head housing 31 can form a pressing contact with the end face of the sealing sleeve 44, and the end face of the male head valve core 32 can form a pressing contact with the end face of the female head valve core shaft 42.

[0060] As an optional implementation, the female head housing 41 is provided with an auxiliary insertion port 413 at one end near the male head housing 31. The inner surface of the auxiliary insertion port 413 is a conical surface. This arrangement makes it easier to insert the male head body 3.

[0061] As an optional implementation, the inner wall of the female head housing 41 is provided with at least one second sealing ring 414. In this embodiment, the number of second sealing rings 414 is preferably two, and the second sealing rings 414 can contact the outer wall of the male head housing 31. When the male head body 3 and the female head body 4 are inserted, the second sealing rings 414 can play a sealing role between the two.

[0062] The docking process for the quick liquid cooling combination joint is as follows: The male head base unit 1 and the male head body 3 form a male head assembly structure, and the female head base unit 2 and the female head body 4 form a female head assembly structure. The two assembly structures approach each other and dock under the action of external force.

[0063] The end of the male head housing 31 is inserted into the interior of the female head housing 41 through the auxiliary insertion port 413. During its movement, under the elastic support of the first return spring 5 of the male head, the male head housing 31 can slide and contact the male head spherical surface 13 through the male head mating spherical surface 311 to deflect the angle. At the same time, under the elastic support of the first return spring 6 of the female head, the female head housing 41 can slide and contact the female head spherical surface 23 through the female head mating spherical surface 411 to deflect the angle.

[0064] As the end of the male head housing 31 is continuously inserted into the female head housing 41, the end of the male head housing 31 comes into contact with the sealing sleeve 44, causing the sealing sleeve 44 to retract and compress the second return spring 43 of the female head. At the same time, the female head valve spindle 42 extends into the male head housing 31, and the end of the female head valve spindle 42 comes into contact with the male head valve core 32, causing the male head valve core 32 to retract and compress the second return spring 33 of the male head. The above process realizes the docking of the valve core, thereby opening the fluid passage.

[0065] After the connection is released, the male head first return spring 5, the female head first return spring 6, the male head second return spring 33, and the female head second return spring 43 are successively reset, so that the male and female head combined structures are in their initial state.

[0066] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
