Description

Technical Field

[0001] This utility model relates to the field of fluid connectors, and in particular to a floating fluid quick connector. Background Technology

[0002] In electronic applications, fluid fittings are used to connect pipes or tubes to cold plates where fluid flow is required for cooling or other similar purposes. Generally, barbed fittings are used to connect the pipe to the cold plate port. Specifically, the pipe is secured to the port by a barb and pushed against the barb to form a secure and sealed fluid connection.

[0003] However, this design has certain drawbacks. The fixed connection between the barb and the port prevents any movement of the tubing. Therefore, this assembly is highly sensitive to misalignment during installation. Even slight deviations in position can put stress on the tubing and connection, potentially leading to damage or leaks over time. The sealed connection makes disassembling and reconnecting the tubing difficult during maintenance or component replacement. Significant force is often required to remove the tubing from the barb, which can damage the tubing or surrounding components, especially in dense systems.

[0004] The aforementioned limitations are more pronounced in applications requiring frequent maintenance or where precise alignment is difficult to achieve. Because the joint or tube cannot support axial or angular movement, it may eventually fail due to mechanical stress or wear. Utility Model Content

[0096] The following description, in conjunction with the accompanying drawings, illustrates the embodiments and technical content of this utility model. However, it should be understood that the embodiments and drawings disclosed herein are merely illustrative and exemplary, and are not intended to limit the scope of this utility model.

[0097] Figure 1 A perspective view of the coupling assembly according to an embodiment of the present invention is shown. Figure 2 Show Figure 1 A cross-sectional view of the coupled components.

[0098] See Figure 2 The coupling assembly 100 includes a housing 102. The housing 102 includes a top cover 104, a middle sleeve 106, and a bottom cover 108. To prevent liquid leakage, the housing 102 may have an O-ring 110. The O-ring 110 is positioned between the top cover 104 and the middle sleeve 106, and between the bottom cover 108 and the middle sleeve 106. The top cover 104 may include a protrusion 112. The protrusion 112 can be used as an outlet valve. The protrusion 112 can be connected to an outlet pipe or tube body, allowing cooling fluid to flow to other parts of the system. The protrusion 112 may include any suitable fastening feature such as a barb, external thread, internal thread, or tube body.

[0099] The middle sleeve 106 has a small opening 114 at a first end near the bottom cover 108 and a large opening 116 at a second end near the top cover 104. The small opening 114 has an inner surface 118 and an edge 120. The inner surface of the bottom cover 108 has a groove 122. The bottom cover 108 also has an opening 124. When the bottom cover 108 is assembled with the middle sleeve 106, the groove 122 is adjacent to the first end of the middle sleeve 106. The top cover 104, the middle sleeve 106, and the bottom cover 108 can be assembled to form a housing 102, and a cavity is formed within the housing 102.

[0100] The coupling assembly 100 may further include a sliding base 126 and an inlet valve 128. The sliding base 126 is located within a cavity of the housing 102. The inlet valve 128 may be partially positioned within the cavity of the housing 102. The sliding base 126 has a first end and a disc portion 130 positioned at the first end. The sliding base 126 further has a second end and a tube portion 132 positioned at the second end. The disc portion 130 may be located within a recess 122 of the bottom cover 108 of the housing 102. The diameter of the disc portion 130 is larger than the diameter of the small opening 114 of the intermediate sleeve 106 or the diameter of the opening 124 of the bottom cover 108. Therefore, the disc portion 130 is confined between the bottom cover 108 and the intermediate sleeve 106, while still allowing radial movement in the x and z directions (i.e., radial movement along the xz plane).

[0101] The sliding base 126 has an inner channel 134 extending through it. An inlet valve 128 is disposed within the inner channel 134 from a first end portion of the sliding base 126. An axial spring 136 is disposed within the inner channel 134 of the tube body portion 132. A spring cap 138 is secured to a second end of the sliding base 126 to prevent the axial spring 136 from sliding out of the sliding base 126. A clamping member 142 is attached to the end of the inlet valve 128 inserted into the inner channel 134 to prevent the inlet valve 128 from being easily removed. Furthermore, when the inlet valve 128 is pushed inward, the clamping member 142 can compress the axial spring 136 axially (i.e., in the +y direction). Therefore, the coupling assembly 100 can be provided with axial movement in the y-direction via the axial spring 136.

[0102] The inner passage 134 includes a tapered portion 140. The tapered portion 140 tapers toward the first end of the sliding base 126. When the inlet valve 128 is inserted into the inner passage 134, an O-ring 110 is provided for sealing. Due to some space in the tapered portion 140 of the inner passage 134, the inlet valve 128 can be angularly moved. The inlet valve 128 can pivot at the first end of the sliding base 126, moving angularly by a certain degree, thereby making the joint flexible to reduce mechanical stress during system assembly or disassembly. The inlet valve 128 has an inner passage for the flow of cooling fluid.

[0103] like Figures 1 to 2 The coupling assembly 100 shown can provide axial, radial, and angular movement to reduce mechanical stress on the joint during assembly and disassembly. Figures 2A to 4C Various different movements of the coupling component 100 are shown.

[0104] Figures 2A to 2B This diagram shows a cross-sectional view of the coupling assembly 100 according to an embodiment of the present invention during radial movement. The disc portion 130 of the sliding base 126 is constrained between the bottom cover 108 and the intermediate sleeve 106 to prevent any axial movement of the sliding base 126. The diameter of the disc portion 130 may be larger than the diameter of the small opening 114 of the intermediate sleeve 106 or the diameter of the opening 124 of the bottom cover 108. An O-ring 110 is located near the opening 124 of the bottom cover 108 and adjacent to the outer surface of the disc portion 130 to prevent cooling fluid leakage. The disc portion 130 is radially movable between the bottom cover 108 and the intermediate sleeve 106, allowing the sliding base 126 to also move radially. Furthermore, since the O-ring 110 provides friction, the sliding base 126 can be stopped at any position.

[0105] Figures 3A to 3B A cross-sectional view of the coupling assembly 100 according to an embodiment of the present invention is shown during axial movement. A clamping member 142 may be attached to one end of the inlet valve 128 inserted into the inner channel 134 to prevent the inlet valve 128 from being easily removed. A spring cap 138 may be secured to the second end of the sliding base 126 to prevent the axial spring 136 from sliding out of the sliding base 126. An O-ring 110 located between the sliding base 126 and the inlet valve 128 prevents cooling fluid leakage. Figure 3A As shown, in the rest position, the axial spring 136 is decompressed and located in the clamp 142. The clamp 142 is located in a support structure 144 to prevent the inlet valve 128 from being easily removed. When the inlet valve 128 is pushed axially (i.e., in the +y direction), the axial spring 136 is compressed, causing the inlet valve 128 to move axially in the +y direction. When the inlet valve 128 is no longer pushed in the +y direction, the axial spring 136 can be decompressed, allowing the inlet valve 128 to return to the rest position.

[0106] Figures 4A to 4CA cross-sectional view of the coupling assembly 100 according to an embodiment of the present invention is shown during angular movement. The inner channel 134 includes a tapered portion 140. The tapered portion 140 tapers toward a first end of the sliding base 126. That is, the opening diameter of the tapered portion 140 near the support structure 144 is larger than the opening diameter of the first end of the sliding base 126. An O-ring 110 located between the sliding base 126 and the inlet valve 128 prevents leakage of cooling fluid. The inlet valve 128 can pivot at the first end of the sliding base 126, moving angularly by a certain degree, thereby making the joint flexible to reduce mechanical stress during system assembly or disassembly. For example, as Figure 4B and 4C As shown, the inlet valve can be tilted along the x and z directions, or in a circular tilt in the xz plane.

[0107] Figures 5A to 5B This diagram shows a cross-sectional view of the coupling assembly 100A according to an embodiment of the present invention during axial movement. The coupling assembly 100A and... Figures 1 to 2 and Figures 3A to 3B The coupling assembly 100 shown is similar. The difference lies in the position of the axial spring. The axial spring 136A is disposed outside the housing 102A, and the inlet valve 128A passes through the axial spring 136A and has a support structure for mounting the axial spring 136A. Since the axial spring 136A is located outside the sliding base 126A, the tube portion is no longer needed. The sliding base 126A still includes the disc portion 130A, the tapered portion 140A, and the support structure 144A. The clamping member 142A is attached to one end of the inlet valve 128A inserted into the inner channel 134A to prevent the inlet valve 128A from being easily removed. Furthermore, the spring cap is no longer needed to cover the axial spring. Figure 5A As shown, in the rest position, the axial spring 136A is decompressed and positioned within the support structure of the inlet valve 128A. The clamp 142A is located within the support structure 144A to prevent the inlet valve 128A from being easily removed. When the inlet valve 128A is pushed axially (i.e., in the +y direction), the axial spring 136A is compressed, causing the inlet valve 128A to move axially in the +y direction. When the inlet valve 128A is no longer pushed in the +y direction, the axial spring 136A can be decompressed, allowing the inlet valve 128A to return to the rest position.

[0108] Figures 6A to 6C This diagram shows a cross-sectional view of the coupling assembly 100B according to an embodiment of the present invention during radial movement. The coupling assembly 100B and... Figures 1 to 2 and Figures 3A to 3BThe coupling assembly 100B is similar to the one shown. The difference is that the coupling assembly 100B allows the inlet valve 128B to automatically reset to its center position. The coupling assembly 100B further includes a sliding sleeve 146B. The sliding sleeve 146B is positioned within the cavity of the housing 102. The sliding base 126B includes a wedge-shaped structure 148B. The wedge-shaped structure 148B is located between the disc portion 130B and the tube portion 132B. The edge 120B of the small opening 114B of the intermediate sleeve 106B is positioned between the disc portion 130B and the wedge-shaped structure 148B. The wedge-shaped structure 148B has a first surface 150B and a second surface 152B. The first surface 150B is adjacent to the inner surface 118B of the small opening 114B of the intermediate sleeve 106B. The second surface 152B is an inclined surface.

[0109] The sliding sleeve 146B has a small opening 154B and a large opening 156B. The diameter of the small opening 154B is slightly smaller than the diameter of the wedge structure 148B, and the edge of the small opening 154B is located on the second surface 152B of the wedge structure 148B of the sliding base 126B. Thus, when the sliding base 126B moves radially in the xz plane, the sliding sleeve 146B can be pushed in the axial direction (i.e., the +y direction) due to the inclined second surface 152B. The sliding sleeve 146B may include a support structure 158B. The support structure 158B is located near the small opening 154B and supports the radial spring 160. When the sliding base 126B moves radially in the xz plane and the sliding sleeve 146B is pushed in the +y direction, the radial spring 160 is compressed. When the sliding sleeve 146B is no longer pushed in the y-direction, the radial spring 160 decompresses, and the sliding base 126B returns to the center position due to the inclined second surface 152B. Therefore, the coupling assembly 100B provides the function of automatically resetting the inlet valve 128B to the center position.

[0110] Figure 7 This diagram shows a cross-sectional view of a coupling assembly 100C having a quick-connect connector 162C according to an embodiment of the present invention. The coupling assembly 100C and... Figures 6A to 6C The coupling assembly 100B shown is similar. The difference lies in that the inlet valve 128C is used to receive a quick-connect fitting 162C. One end of the inlet valve 128C is inserted into the inner channel 134C of the sliding base 126C, and the other end of the inlet valve 128C is used to receive the quick-connect fitting 162C. The quick-connect configuration can be used in a wide range of applications and can improve the efficiency of the coupling assembly 100C in the assembly and disassembly process.

[0111] Figures 8A to 8C The coupling component 200 according to an embodiment of the present invention is shown. Figures 8A to 8B A perspective view of the coupling component 200 according to an embodiment of the present invention is shown. Figure 8C A cross-sectional view of coupling component 200 is shown. Coupling component 200 and... Figures 1 to 2 The coupling component 100 shown is similar.

[0112] See Figure 8C The coupling assembly 200 includes a housing 202, a sliding base 204, an inlet valve 206, and an outlet valve 208. Compared to Figures 1 to 2 The coupling assembly 100 shown has a housing 202 as a single element. The housing 202 includes a large opening 210 and a small opening 212. The small opening 212 has an edge 214 and an inner surface 216. The housing 202 further has a recess 218. The recess 218 is located on the inner surface of the housing 202 and is close to the small opening 212.

[0113] A sliding base 204 is positioned within the cavity of the housing 202. A first end 220 of the sliding base 204 is inserted into a small opening 212 of the housing 202, and a second end 222 of the sliding base 204 is positioned at a large opening 210 of the housing 202. The sliding base 204 has a wedge-shaped structure 224. The wedge-shaped structure 224 is located on the inner surface 216 of the small opening 212 of the housing 202. A gasket 226 is positioned at the first end 220 of the sliding base 204, thereby positioning the small opening 212 of the housing 202 between the gasket 226 and the wedge-shaped structure 224. Therefore, the sliding base 204 is fixed to the housing 202. A clamping member 228 is used to secure the gasket 226 to prevent it from sliding out of the sliding base 204. The sliding base 204 includes an inner channel 230. The inner channel 230 has a tapered portion 232 and a tubular portion 234. The tapered portion 232 extends from the first end 220 of the sliding base 204 to the gasket 226. The tube portion 234 extends from the gasket 226 to the second end 222 of the sliding base 204. The tapered portion 232 tapers from the first end 220 toward the tube portion 234. The tube portion 234 may have a uniform diameter, and the diameter of the tube portion is larger than the maximum diameter of the tapered portion 232.

[0114] The inlet valve 206 is partially disposed within the inner channel 230 of the sliding base 204. Specifically, the inlet valve 206 is disposed within the converging portion 232 and partially disposed within the tube body 234. The outlet valve 208 is partially disposed within the inner channel 230 of the sliding base 204. Specifically, the outlet valve 208 is partially disposed within the tube body 234 but not within the converging portion 232. A gasket 236 is attached to the end of the outlet valve 208 disposed within the tube body 234 to prevent the outlet valve 208 from sliding into the converging portion 232. The portion of the inlet valve 206 disposed within the tube body 234 is inserted into the outlet valve 208 to allow cooling fluid to flow through. An O-ring may be provided at the connection between the inlet valve 206 and the outlet valve 208 to prevent cooling fluid leakage. An axial spring 238 is disposed within the inner channel 230 of the tube body 234 and is fitted onto the outlet valve 208. One end of the axial spring 238 is located at the washer 236. The sliding base 204 further includes a clamping member 240. The clamping member 240 is located near the second end 222 so that the axial spring 238 is confined within the tube portion 234 and cannot slide out of the sliding base 204.

[0115] The coupling assembly 200 provides axial, radial, and angular movement of the inlet valve 206 to reduce mechanical stress on the joint during assembly and disassembly. Figures 9A to 11C Various different movements of the coupling component 200 are shown.

[0116] Figures 9A to 9B A cross-sectional view of the coupling assembly 200 according to an embodiment of the present invention is shown when it is moved axially. Figure 9A The coupling assembly 200 is shown in its rest position. The axial spring 238 is decompressed. When the inlet valve 206 and outlet valve 208 are pushed along the +y direction, the axial spring 238 is compressed and moves axially. When the inlet valve 206 and outlet valve 208 are no longer pushed, the axial spring 238 decompresses, and the inlet valve 206 and outlet valve 208 return to their rest positions. Therefore, the coupling assembly 200 can provide axial movement along the +y direction using the axial spring 238.

[0117] Figures 10A to 10C A cross-sectional view of the coupling assembly 200 according to an embodiment of the present invention is shown when it is moved radially. Figure 10AThe coupling assembly 200 is shown in its rest position (i.e., center position). A small opening 212 in the housing 202 is positioned between the gasket 226 and the wedge structure 224 to prevent the sliding base 204 from moving in the y-direction. Specifically, the diameter of the small opening 212 in the housing 202 is slightly smaller than the diameters of the gasket 226 and the wedge structure 224. Furthermore, there is a space between the edge 214 of the small opening 212 and the sliding base 204 to allow the sliding base 204 to move in the x and z directions. That is, the sliding base 204 can move freely within the small opening 212 in the xz plane. In this way, the coupling assembly 200 can provide radial movement using the small opening 212 in the housing 202.

[0118] Figures 11A to 11C A cross-sectional view of the coupling assembly 200 according to an embodiment of the present invention is shown when it is angularly moved. Figure 11A The coupling assembly 200 is shown in its rest position, i.e., its center position. The tapering portion 232 of the inner channel 230 tapers from the first end 220 toward the tube body portion 234. The inlet valve 206 can pivot at the narrowest point of the tapering portion 232, moving by a certain angular degree. Therefore, the inlet valve 206 can be rotated by using the narrowest part of the tapering portion 232 as a pivot point.

[0119] Figures 12A to 12C This diagram shows a cross-sectional view of the coupling assembly 200A according to an embodiment of the present invention during radial movement. The coupling assembly 200A and... Figures 8A to 8C The coupling assembly 200A is similar to the one shown. The difference is that the coupling assembly 200A allows the inlet valve 206A to automatically reset to its central position. The coupling assembly 200A further includes a sliding sleeve 242A. The sliding sleeve 242A is positioned within the cavity of the housing 202A. The sliding sleeve 242A has a small opening 244A and a large opening 246A. The edge of the small opening 244A is located within the wedge-shaped structure 224A of the sliding base 204A. Specifically, the small opening 244A is located on the inclined surface of the wedge-shaped structure 224A. A radial spring 248A is disposed within the sliding sleeve 242A and located on the inner surface of the small opening 244A. The housing 202A further includes a spring cap 250A. The spring cap 250A is close to the large opening 210A to prevent the radial spring 248A from sliding out of the housing 202A.

[0120] When the sliding base 204A moves radially in the xz plane and the sliding sleeve 242A is pushed by the wedge structure 224A in the +y direction, the radial spring 248A is compressed. When the sliding base 204A is no longer pushed in the y direction, the radial spring 248A is decompressed, and the sliding base 204A returns to the center position due to the inclined surface of the wedge structure 224A. Therefore, the coupling assembly 200A allows the inlet valve 206A to automatically return to the center position.

[0121] Figures 13A to 13B This diagram shows a cross-sectional view of the coupling assembly 200B according to an embodiment of the present invention during axial movement. The coupling assembly 200B and... Figures 12A to 12C Similar to the coupling assembly 200A shown, coupling assembly 200B allows the sliding base 204B to automatically reset. The difference is that, compared to coupling assembly 200A, coupling assembly 200B provides the opposite axial movement. For example... Figure 13A As shown, the outlet valve 208B is positioned outside the sliding base 204B. More specifically, the outlet valve 208B is positioned outside the housing 202B. The outlet valve 208B has a wider end connected to a first end 220B of the sliding base 204B, preventing the outlet valve 208B from sliding into the sliding base 204B. The inlet valve 206B is disposed within the inner channel 230B and includes a disc structure 262B. The disc structure 262B is located near the large opening 222B of the sliding base 204B. The disc structure 262B can serve as a spring cap for the axial spring 238B.

[0122] like Figure 13A As shown, the coupling assembly 200B is in the rest position. The axial spring 238B is in a decompressed state. Figure 13B As shown, when the inlet valve 206B and outlet valve 208B are pushed in the -y direction, the axial spring 238B is compressed and moves axially. When the inlet valve 206B and outlet valve 208B are no longer pushed, the axial spring 238B is decompressed, allowing the inlet valve 206B and outlet valve 208B to return to their rest positions. In this way, the coupling assembly 200B can provide reverse axial movement in the -y direction using the axial spring 238B.

[0123] Figures 14A to 14B This diagram shows a cross-sectional view of the coupling assembly 200C according to an embodiment of the present invention during axial movement. The coupling assembly 200C and... Figures 13A to 13B Similar to the coupling assembly 200B shown, coupling assembly 200C provides reverse axial movement. The difference is that coupling assembly 200C does not allow the inlet valve 206C to automatically reset. (As shown) Figure 14A As shown, the outlet valve 208C is located outside the sliding base 204C. Specifically, the outlet valve 208C is disposed outside the housing 202C. The outlet valve 208C has a wider end connected to the first end 220C of the sliding base 204C, preventing the outlet valve 208C from sliding into the sliding base 204C. The inlet valve 206C is disposed within the inner channel 230C and includes a disc structure 262C. The disc structure 262C is located near the large opening 222C of the sliding base 204C. The disc structure 262C can serve as a spring cap for the axial spring 238C.

[0124] like Figure 14A As shown, the coupling assembly 200C is in the rest position. The axial spring 238C is in a decompressed state. Figure 14B As shown, when the inlet valve 206C and outlet valve 208C are pushed in the -y direction, the axial spring 238C is compressed and moves axially. When the inlet valve 206C and outlet valve 208C are no longer pushed, the axial spring 238C is decompressed, allowing the inlet valve 206C and outlet valve 208C to return to their rest positions. Therefore, the coupling assembly 200C can provide reverse axial movement in the -y direction using the axial spring 238C.

[0125] Figure 15 A cross-sectional view of a coupling assembly 200D having a quick-connect connector 264D according to an embodiment of the present invention is shown. The coupling assembly 200D and... Figures 12A to 12C The coupling assembly 200A shown is similar. The difference lies in that the inlet valve 206D is used to receive a quick-connect fitting 264D. One end of the inlet valve 206D is inserted into the inner channel 230D of the sliding base 204D, and the other end of the inlet valve 206D is used to receive the quick-connect fitting 264D. The quick-connect configuration can be used in a wide range of applications and can improve the efficiency of the coupling assembly 200D during assembly and disassembly.

[0126] Figures 16A to 16C The coupling component 300 according to an embodiment of the present invention is shown. Figures 16A to 16B A perspective view of the coupling component 300 is shown. Figure 16C A cross-sectional view of coupling component 300 is shown. Coupling component 300 and Figures 8A to 8C The coupling component 200 shown is similar.

[0127] See Figure 16C The coupling assembly 300 includes a housing 302, a sliding base 304, an inlet valve 306, and an outlet valve 308. Compared to Figures 8A to 8C The coupling assembly 200 shown has a reduced size housing 302, suitable for a compact design of the cooling system. Housing 302 includes a large opening 310 and a small opening 312. The small opening 312 has an edge 314 and an inner surface 316. Housing 302 further has a recess 318. The recess 318 is located on the inner surface of housing 302 and near the small opening 312.

[0128] A sliding base 304 is positioned within a groove 318 of the housing 302. A first end 320 of the sliding base 304 is inserted into a small opening 312 of the housing 302, and a second end 322 of the sliding base 304 is positioned within the groove 318 of the housing 302. Due to the compact size of the coupling assembly 300, the sliding base 304 does not have a wedge-shaped structure; instead, the sliding base 304 includes a disc structure 324. The disc structure 324 has a recess 334 positioned within the groove 318. A nut 326 is disposed at the first end 320 of the sliding base 304, positioning the small opening 312 of the housing 302 between the nut 326 and the disc structure 324. Therefore, the sliding base 304 is fixed to the housing 302. The sliding base 304 has an inner channel 330 extending through it. The inner channel 330 has a tapered portion 332. The tapered portion 332 tapers from the first end 320. The tapered portion 332 widens towards the disk structure 324 and connects with the recess 334. The diameter of the recess 334 is larger than the maximum diameter of the tapered portion 332.

[0129] The first end 340 of the inlet valve 306 is inserted into the inner channel 330 from the second end 322 of the sliding base 304, and then into the outlet valve 308 located at the second end 322 of the sliding base 304, allowing cooling fluid to flow through. An O-ring 336 is positioned at the connection between the inlet valve 306 and the outlet valve 308 to prevent cooling fluid leakage. An axial spring 338 is disposed within the recess 334 of the disc structure 324 and fitted onto the inlet valve 306. One end of the axial spring 338 is located within the recess 334, and the other end of the axial spring 338 is located at the flange 342 of the second end 344 of the inlet valve 306. Therefore, the axial spring 338 cannot slide out of the inlet valve 306. The inlet valve 306 is used to receive a quick-connect coupling 346. The quick-connect configuration can be used in a wide range of applications and can improve the efficiency of the coupling assembly 300 during assembly and disassembly.

[0130] The coupling assembly 300 provides axial, radial, and angular movement of the inlet valve 306 to reduce mechanical stress on the joint during assembly and disassembly. Figures 17A to 19C Various different movements of the coupling component 300 are shown.

[0131] Figures 17A to 17B A cross-sectional view of the coupling assembly 300 according to an embodiment of the present invention is shown when it moves axially. Figure 17A The coupling assembly 300 is shown in its rest position. The axial spring 338 is in a decompressed state. When the inlet valve 306 is pushed along the +y direction, the axial spring 338 is compressed and moves axially. When the inlet valve 306 is no longer pushed, the axial spring 338 decompresses, allowing the inlet valve 306 to return to its rest position. Therefore, the coupling assembly 300 utilizes the axial spring 338 to provide axial movement along the +y direction.

[0132] Figures 18A to 18B This diagram shows a cross-sectional view of the coupling assembly 300 according to an embodiment of the present invention during radial movement. A small opening 312 of the housing 302 is positioned between the nut 326 and the disk structure 324 to prevent the sliding base 304 from moving in the y-direction. Specifically, the diameter of the small opening 312 of the housing 302 is slightly smaller than the diameters of the nut 326 and the disk structure 324. Furthermore, a space 350 is provided between the edge 314 of the small opening 312 and the sliding base 304 to allow the sliding base 304 to move in the x and z directions. That is, the sliding base 304 can move freely within the small opening 312 in the xz plane. Therefore, the coupling assembly 300 can provide radial movement using the small opening 312 of the housing 302.

[0133] Figures 19A to 19C A cross-sectional view of the coupling assembly 300 according to an embodiment of the present invention is shown when it is angularly moved. Figure 19A The coupling assembly 300 is shown in its rest position, i.e., its center position. The tapering portion 332 of the inner channel 330 tapers from the first end 320 toward the disc structure 324. The inlet valve 306 can pivot at the narrowest point of the tapering portion 332, moving by a certain angular degree. Therefore, the inlet valve 306 can be rotated by using the narrowest part of the tapering portion 332 as a pivot point.

[0134] Figure 20 Show Figures 16A to 16C An enlarged cross-sectional view of the sliding base 304 of the coupling assembly 300. The tapered portion 332 has a 2° taper. That is, the coupling assembly 300 can provide a 2° taper to the inlet valve 306. The coupling assembly is not limited to a 2° taper. Depending on the application of the coupling assembly, the taper size can be set accordingly to provide the required angular movement.

[0135] Figures 21A to 21C The coupling component 400 according to an embodiment of the present invention is shown. Figures 21A to 21B A perspective view of the coupling component 400 is shown. Figure 21C A cross-sectional view of coupling component 400 is shown. Coupling component 400 and Figures 16A to 16C The coupling component 300 shown is similar.

[0136] See Figure 21C The coupling assembly 400 includes a housing 402, a sliding base 404, an inlet valve 406, and an outlet valve 408. Compared to Figures 16A to 16CThe coupling assembly 300 shown has a narrower housing 402 in the x-direction, making it suitable for compact designs of cooling systems. The housing 402 includes a large opening 410 and a small opening 412. The small opening 412 has an edge 414 and an inner surface 416. The housing 402 further includes a recess 418. The recess 418 is located on the inner surface of the housing 402 and is close to the small opening 412.

[0137] A sliding base 404 is positioned within a groove 418 of the housing 402. A first end 420 of the sliding base 404 is inserted into a small opening 412 of the housing 402, and a second end 422 of the sliding base 404 is positioned within the groove 418 of the housing 402. Due to the compact size of the coupling assembly 400, the sliding base 404 does not have a wedge-shaped structure; instead, a disc structure 424 with a recess 434 is positioned within the groove 418. A nut 426 is disposed at the first end 420 of the sliding base 404, thereby positioning the small opening 412 of the housing 402 between the nut 426 and the disc structure 424. Therefore, the sliding base 404 is fixed to the housing 402. The sliding base 404 has an inner channel 430. The inner channel 430 has a tapering portion 432. The tapering portion 432 tapers from the first end 420 toward the disc structure 424 and connects to the recess 434. The diameter of the recess 434 is greater than the maximum diameter of the tapered portion 432.

[0138] The first end 440 of the inlet valve 406 is inserted into the inner channel 430 from the first end 420 of the sliding base 404 and into the outlet valve 408 located at the second end 422 of the sliding base 404, allowing cooling fluid to flow through. An O-ring 436 is positioned at the connection between the inlet valve 406 and the outlet valve 408 to prevent cooling fluid leakage. An axial spring 438 is disposed within the recess 434 of the disc structure 424 and fitted onto the inlet valve 406. One end of the axial spring 438 is located within the recess 434, and the other end of the axial spring 438 is located at the flange 442 of the second end 444 of the inlet valve 406. Therefore, the axial spring 438 cannot slide out of the inlet valve 406. The inlet valve 406 is used to receive a quick-connect coupling 446. The quick-connect configuration can be used in a wide range of applications and can improve the efficiency of the coupling assembly 400 during assembly and disassembly.

[0139] The coupling assembly 400 provides axial, radial, and angular movement of the inlet valve 406 to reduce mechanical stress on the joint during assembly and disassembly. Figures 22A to 24C Various different movements of the coupling component 400 are shown.

[0140] Figures 22A to 22B A cross-sectional view of the coupling assembly 400 according to an embodiment of the present invention is shown when it is moved axially. Figure 22AThe coupling assembly 400 is shown in its rest position. The axial spring 438 is in a decompressed state. When the inlet valve 406 is pushed along the +y direction, the axial spring 438 is compressed and moves axially. When the inlet valve 406 is no longer pushed, the axial spring 438 decompresses, allowing the inlet valve 406 to return to its rest position. Therefore, the coupling assembly 400 utilizes the axial spring 438 to provide axial movement along the +y direction.

[0141] Figures 23A to 23B This diagram shows a cross-sectional view of the coupling assembly 400 according to an embodiment of the present invention during radial movement. A small opening 412 of the housing 402 is positioned between the nut 426 and the disk structure 424 to prevent the sliding base 404 from moving in the y-direction. Specifically, the diameter of the small opening 412 of the housing 402 is slightly smaller than the diameters of the nut 426 and the disk structure 424. Furthermore, a space 450 is provided between the edge 414 of the small opening 412 and the sliding base 404 to allow the sliding base 404 to move in both the x and z directions. That is, the sliding base 404 can move freely within the small opening 412 in the xz plane. Therefore, the coupling assembly 400 can provide radial movement using the small opening 412 of the housing 402. The space 450 of the coupling assembly 400 is smaller than the space 350 of the coupling assembly 300. Therefore, the range of radial movement of coupling component 400 is smaller than that of coupling component 300, which makes coupling component 400 more advantageous when the assembly area is limited.

[0142] Figures 24A to 24C A cross-sectional view of the coupling assembly 400 according to an embodiment of the present invention is shown when it is angularly moved. Figure 24A The coupling assembly 400 is in the rest position, i.e., the center position. The tapering portion 432 of the inner channel 430 tapers from the disc structure 424 toward the first end 420. The inlet valve 406 can pivot at the narrowest point of the tapering portion 432, moving by a certain angular degree. That is, the inlet valve 406 can be rotated by using the narrowest part of the tapering portion 432 as a pivot point.
