Description

Technical Field

[0001] The present invention relates to the field of fluid connectors, and more particularly to a floating fluid quick-connect fitting. Background Art

[0002] In electronic applications, fluid connectors are used to connect a tube or pipe to a cold plate where fluid flow is required for cooling or other similar purposes. Generally, barbed fittings are used to connect the tube to the port of the cold plate. Specifically, the barbs are fixed to the port and the tube is pushed onto the barbs to form a secure and sealed fluid connection.

[0003] However, this design has certain drawbacks. The fixed connection between the barbs and the port prevents any movement of the tube. Therefore, this assembly is highly sensitive to misalignment during installation. Any minor deviation in position may exert pressure on the tube and the connection, which may lead to damage or leakage over long-term use. The sealed connection makes it difficult to disassemble and reconnect the tube when maintaining or replacing the components. Usually, a great deal of force is required to remove the tube from the barbs, which may damage the tube or surrounding components, especially in a dense system.

[0004] The aforementioned limitations are more evident in applications that require frequent maintenance or are difficult to achieve precise alignment. Since the connector or tube cannot support axial or angular movement, it may be subject to mechanical stress or wear and eventually fail. Summary of the Invention

[0096] The following describes the implementation manners and technical content of the present invention in conjunction with the drawings. It should be understood, however, that the implementation manners and drawings disclosed herein are illustrative and exemplary only, and are not intended to limit the scope of the present invention.

[0097] Figure 1A A perspective view of a coupling assembly according to an embodiment of the present invention is shown. Figure 1B Shown Figure 1A A cross-sectional view of the coupling assembly.

[0098] Referring to Figure 1B , the coupling assembly 100 includes a housing 102. The housing 102 includes a top cover 104, a middle section 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 section sleeve 106 and between the bottom cover 108 and the middle section 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 a liquid outlet pipe or a pipe body, so that the cooling fluid can flow to other parts of the system. The protrusion 112 may include any suitable fastening features such as a barb, an external thread, an internal thread, or a pipe body.

[0099] The middle section sleeve 106 has a small opening 114 at the first end near the bottom cover 108 and a large opening 116 at the 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 further has an opening 124. When the bottom cover 108 is assembled with the middle section sleeve 106, the groove 122 is adjacent to the first end of the middle section sleeve 106. The top cover 104, the middle section sleeve 106, and the bottom cover 108 can be assembled together to form the housing 102, and a cavity is formed inside 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 inside the cavity of the housing 102. The inlet valve 128 may be partially located inside the cavity of the housing 102. The sliding base 126 has a first end and a disc portion 130 located at the first end. The sliding base 126 further has a second end and a tube portion 132 located at the second end. The disc portion 130 may be located inside the groove 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 middle section sleeve 106 or the diameter of the opening 124 of the bottom cover 108. Therefore, the disc portion 130 is restricted between the bottom cover 108 and the middle section sleeve 106, while still providing radial movement in the x direction and the z direction (i.e., radial movement along the x-z plane).

[0101] The sliding base 126 has an inner channel 134 passing through the sliding base 126. The inlet valve 128 is partially disposed inside the inner channel 134 from the first end of the sliding base 126. An axial spring 136 is disposed inside the inner channel 134 of the tube portion 132. A spring cap 138 may be fixed to the second end of the sliding base 126 to prevent the axial spring 136 from slipping out of the sliding base 126. 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. In addition, when the inlet valve 128 is pushed inward, the clamping member 142 can axially compress the axial spring 136 (i.e., in the +y direction). Therefore, the coupling assembly 100 can provide axial movement in the y direction through the axial spring 136.

[0102] The inner channel 134 includes a tapered portion 140. The tapered portion 140 tapers towards the first end of the sliding base 126. When the inlet valve 128 is inserted into the inner channel 134, an O-ring 110 is provided for sealing purposes. Due to some space in the tapered portion 140 of the inner channel 134, the inlet valve 128 can make angular movement. The inlet valve 128 can pivot at the first end of the sliding base 126 to angularly move by a certain number of degrees, thereby making the joint elastic to reduce mechanical stress during the assembly or disassembly of the system. The inlet valve 128 has an inner channel for the flow of cooling fluid.

[0103] As Figures 1A to 1B The coupling assembly 100 as shown can provide axial movement, radial movement, and angular movement to reduce mechanical stress during the assembly and disassembly of the joint. Figures 2A to 4C Shows various different movements of the coupling assembly 100.

[0104] Figures 2A to 2B Shows a cross-sectional view of the coupling assembly 100 according to an embodiment of the present invention when moving radially. The disc portion 130 of the sliding base 126 is restricted between the bottom cover 108 and the middle section sleeve 106 to prevent any axial movement of the sliding base 126. The diameter of the disc portion 130 can be larger than the diameter of the small opening 114 of the middle section sleeve 106 or the diameter of the opening 124 of the bottom cover 108. The O-ring 110 is located near the opening 124 of the bottom cover 108 and is adjacent to the outer surface of the disc portion 130 to prevent leakage of the cooling fluid. The disc portion 130 can move radially between the bottom cover 108 and the middle section sleeve 106, so that the sliding base 126 can also move radially. In addition, since the O-ring 110 can provide frictional force, the sliding base 126 can stop at any position.

[0105] Figures 3A to 3B Shows a cross-sectional view of the coupling assembly 100 according to an embodiment of the present invention when moving axially. A clamping member 142 can 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 can be fixed to the second end of the sliding base 126 to prevent the axial spring 136 from slipping out of the sliding base 126. The O-ring 110 located between the sliding base 126 and the inlet valve 128 can prevent leakage of the cooling fluid. As Figure 3A shown, in the stationary position, the axial spring 136 is decompressed and located at the clamping member 142. The clamping member 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 to cause 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 to cause the inlet valve 128 to return to the stationary position.

[0106] Figures 4A to 4CA cross-sectional view of the coupling assembly 100 according to an embodiment of the present invention during angular movement is shown. The inner channel 134 includes a tapered portion 140. The tapered portion 140 tapers towards the 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. The O-ring 110 located between the sliding base 126 and the inlet valve 128 can prevent the leakage of the cooling fluid. The inlet valve 128 can pivot at the first end of the sliding base 126 and move angularly by a certain number of degrees, so that the joint is elastic to reduce the mechanical stress during the assembly or disassembly of the system. For example, as Figure 4B and 4C shown, the inlet valve can be tilted in the x direction and the z direction, or circularly tilted in the x-z plane.

[0107] Figures 5A to 5B A cross-sectional view of the coupling assembly 100A during axial movement according to an embodiment of the present invention is shown. The coupling assembly 100A is similar to Figures 1A to 1B and Figures 3A to 3B the coupling assembly 100 shown. 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 the axial spring 136A to be disposed. Since the axial spring 136A is located outside the sliding base 126A, the tube body portion is no longer needed. The sliding base 126A still includes a disc portion 130A, a tapered portion 140A, and a support structure 144A. The clamping member 142A is attached to one end where the inlet valve 128A is inserted into the inner channel 134A to prevent the inlet valve 128A from being easily removed. In addition, the spring cap is no longer needed to cover the axial spring. As Figure 5A shown, in the stationary position, the axial spring 136A is decompressed and located at the support structure of the inlet valve 128A. The clamping member 142A is located at 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 to move the inlet valve 128A 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 to reset the inlet valve 128A to the stationary position.

[0108] Figures 6A to 6C A cross-sectional view of the coupling assembly 100B during radial movement according to an embodiment of the present invention is shown. The coupling assembly 100B is similar to Figures 1A to 1B and Figures 3A to 3BSimilar to the coupling component 100 shown. The difference is that the coupling component 100B can make the inlet valve 128B automatically reset to the central position of the inlet valve 128B. The coupling component 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 structure 148B. The wedge structure 148B is located between the disc portion 130B and the tube portion 132B. The edge 120B of the small opening 114B of the middle section sleeve 106B is positioned between the disc portion 130B and the wedge structure 148B. The wedge 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 middle section 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. In this way, when the sliding base 126B moves radially in the x-z 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 close to the small opening 154B and supports the radial spring 160. When the sliding base 126B moves radially in the x-z 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 causes the sliding base 126B to reset to the central position due to the inclined second surface 152B. Therefore, the coupling component 100B can provide the function of automatically resetting the inlet valve ********** to the central position.

[0110] Figure 7 A cross-sectional view of a coupling component 100C having a quick-connect fitting 162C according to an embodiment of the present invention is shown. The coupling component 100C is similar to Figures 6A to 6C the coupling component 100B shown. The difference is 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 adopted in a wide range of applications and can improve the efficiency of the coupling component 100C during the assembly and disassembly process.

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

[0112] Refer to Figure 8C . The coupling component 200 includes a housing 202, a sliding base 204, an inlet valve 206, and an outlet valve 208. Compared with Figures 1A to 1B the coupling component 100 shown, the housing 202 is 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 groove 218. The groove 218 is located on the inner surface of the housing 202 and near the small opening 212.

[0113] The sliding base 204 is positioned within the cavity of the housing 202. The first end 220 of the sliding base 204 is inserted into the small opening 212 of the housing 202, and the second end 222 of the sliding base 204 is positioned at the 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 device 202. A gasket 226 is positioned at the first end 220 of the sliding base 204, such that the small opening 212 of the housing 202 is positioned between the gasket 226 and the wedge-shaped structure 224. Thus, the sliding base 204 is fixed to the housing 202. A clamping member 228 is used to fix the gasket 226 to prevent the gasket 226 from slipping 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 tubular 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 towards the tubular portion 234. The tubular portion 234 may have a uniform diameter, and the diameter of the tubular portion is greater 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 tapered portion 232 and partially within the tubular portion 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 tubular portion 234 but not within the tapered portion 232. A gasket 236 is attached to one end of the outlet valve 208 disposed within the tubular portion 234 to prevent the outlet valve 208 from sliding into the tapered portion 232. The portion of the inlet valve 206 disposed within the tubular portion 234 is inserted into the outlet valve 208 to allow the 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 leakage of the cooling fluid. The axial spring 238 is disposed within the inner channel 230 of the tubular portion 234 and sleeved on the outlet valve 208. One end of the axial spring 238 is located at the gasket 236. The sliding base 204 further includes a clamping member 240. The clamping member 240 is near the second end 222 to confine the axial spring 238 within the tubular portion 234 and prevent it from sliding out of the sliding base 204.

[0115] The coupling assembly 200 can provide axial, radial, and angular movement of the inlet valve 206 to reduce mechanical stress during the assembly and disassembly of the joint. Figures 9A to 11C Illustrates various different movements of the coupling assembly 200.

[0116] Figures 9A to 9B Illustrates a cross-sectional view of the coupling assembly 200 moving axially according to an embodiment of the present invention. Figure 9A Illustrates the coupling assembly 200 in a stationary position. Here, the axial spring 238 is in a decompressed state. When the inlet valve 206 and the outlet valve 208 are pushed in the +y direction, the axial spring 238 is compressed and moves axially. When the inlet valve 206 and the outlet valve 208 are no longer pushed, the axial spring 238 decompresses, and the inlet valve 206 and the outlet valve 208 return to the stationary position. Thus, the coupling assembly 200 can provide axial movement in the +y direction by utilizing the axial spring 238.

[0117] Figures 10A to 10C Illustrates a cross-sectional view of the coupling assembly 200 moving radially according to an embodiment of the present invention. Figure 10AThe coupling assembly 200 in a stationary position (i.e., the central position) is shown. The small opening 212 of 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 of the housing 202 is slightly smaller than the diameter of the gasket 226 and the diameter of the wedge structure 224. In addition, 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-direction and the z-direction. That is, the sliding base 204 can move freely within the small opening 212 in the x-z plane. In this way, the coupling assembly 200 can provide radial movement by using the small opening 212 of 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 during angular movement is shown. Figure 11A The coupling assembly 200 in a stationary position (i.e., the central position) is shown. The tapered portion 232 of the inner channel 230 tapers from the first end 220 towards the tube body portion 234. The inlet valve 206 can pivot at the narrowest part of the tapered portion 232 by a certain number of degrees for angular movement. Therefore, the inlet valve 206 can rotate by using the narrowest part of the tapered portion 232 as a pivot point.

[0119] Figures 12A to 12C A cross-sectional view of the coupling assembly 200A according to an embodiment of the present invention during radial movement is shown. The coupling assembly 200A is similar to Figures 8A to 8C the coupling assembly 200 shown. The difference is that the coupling assembly 200A can automatically reset the inlet valve 206A to the central position of the inlet valve 206A. 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 at the wedge structure 224A of the sliding base 204A. Specifically, the small opening 244A is located on the inclined surface of the wedge structure 224A. A radial spring 248A is disposed within the sliding sleeve 242A and is 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 x-z plane and the sliding sleeve 242A is pushed in the +y direction by the wedge structure 224A, the radial spring 248A is compressed. When the sliding base 204A is no longer pushed in the y-direction, the radial spring 248A decompresses and causes the sliding base 204A to reset to the central position due to the inclined surface of the wedge structure 224A. Therefore, the coupling assembly 200A can automatically reset the inlet valve 206A to the central position.

[0121] Figures 13A to 13B Shows a cross-sectional view of the coupling assembly 200B according to an embodiment of the present invention when moving axially. The coupling assembly 200B is similar to Figures 12A to 12C the shown coupling assembly 200A, and the coupling assembly 200B can automatically reset the sliding base 204B. The difference is that, compared with the coupling assembly 200A, the coupling assembly 200B provides reverse axial movement. As Figure 13A 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 the first end 220B of the sliding base 204B, so that the outlet valve 208B cannot slide into the sliding base 204B. The inlet valve 206B is disposed in the inner channel 230B and includes a disc structure 262B. The disc structure 262B is close to 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] As Figure 13A shown, the coupling assembly 200B is in a stationary position. Among them, the axial spring 238B is in a decompressed state. As Figure 13B shown, when the inlet valve 206B and the outlet valve 208B are pushed in the -y direction, the axial spring 238B is compressed and moves axially. When the inlet valve 206B and the outlet valve 208B are no longer pushed, the axial spring 238B will decompress to reset the inlet valve 206B and the outlet valve 208B to the stationary position. In this way, the coupling assembly 200B can provide reverse axial movement in the -y direction by using the axial spring 238B.

[0123] Figures 14A to 14B Shows a cross-sectional view of the coupling assembly 200C when moving axially according to an embodiment of the present invention. The coupling assembly 200C is similar to Figures 13A to 13B the shown coupling assembly 200B, and the coupling assembly 200C can provide reverse axial movement. The difference is that the coupling assembly 200C cannot automatically reset the inlet valve 206C. As Figure 14A 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, so that the outlet valve 208C cannot slide into the sliding base 204C. The inlet valve 206C is disposed in the inner channel 230C and includes a disc structure 262C. The disc structure 262C is close to 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] As Figure 14AAs shown, the coupling assembly 200C is in the rest position. Among them, the axial spring 238C is in the decompressed state. As Figure 14B shown, when the inlet valve 206C and the outlet valve 208C are pushed in the -y direction, the axial spring 238C is compressed and moves axially. When the inlet valve 206C and the outlet valve 208C are no longer pushed, the axial spring 238C decompresses to reset the inlet valve 206C and the outlet valve 208C to the rest position. Therefore, the coupling assembly 200C can provide reverse axial movement in the -y direction by using the axial spring 238C.

[0125] Figure 15 A cross-sectional view of a coupling assembly 200D having a quick-connect fitting 264D according to an embodiment of the present invention is shown. The coupling assembly 200D is similar to Figures 12A to 12C the coupling assembly 200A shown. The difference is 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 adopted in a wide range of applications and can improve the efficiency of the coupling assembly 200D during the assembly and disassembly processes.

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

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

[0128] The sliding base 304 is positioned within the recess 318 of the housing 302. The first end 320 of the sliding base 304 is inserted into the small opening 312 of the housing 302, and the second end 322 of the sliding base 304 is positioned within the recess 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 recess 318. A nut 326 is disposed at the first end 320 of the sliding base 304 such that the small opening 312 of the housing 302 is positioned between the nut 326 and the disc structure 324. Thus, the sliding base 304 is fixed to the housing 302. The sliding base 304 has an inner channel 330 that extends through the sliding base 304. 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 disc structure 324 and is connected to the recess 334. The diameter of the recess 334 is greater 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 is inserted into the outlet valve 308 located at the second end 322 of the sliding base 304 so that the cooling fluid can flow through. An O-ring 336 is positioned at the connection between the inlet valve 306 and the outlet valve 308 to prevent leakage of the cooling fluid. An axial spring 338 is disposed within the recess 334 of the disc structure 324 and is sleeved on the inlet valve 306. One end of the axial spring 338 is within the recess 334, and the other end of the axial spring 338 is at the flange 342 of the second end 344 of the inlet valve 306. Thus, the axial spring 338 cannot slide out of the inlet valve 306. The inlet valve 306 is used to receive a quick-connect fitting 346. The quick-connect configuration can be employed 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 can provide axial movement, radial movement, and angular movement of the inlet valve 306 to reduce the mechanical stress on the joint during assembly and disassembly. Figures 17A to 19C Shows various different movements of the coupling assembly 300.

[0131] Figures 17A to 17B Shows a cross-sectional view of the coupling assembly 300 during axial movement according to an embodiment of the present invention. Figure 17A Shows the coupling assembly 300 in a stationary position. Wherein, the axial spring 338 is in a decompressed state. When the inlet valve 306 is pushed in 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 to reset the inlet valve 306 to the stationary position. Thus, the coupling assembly 300 can provide axial movement in the +y direction by using the axial spring 338.

[0132] Figures 18A to 18B A cross-sectional view of the coupling assembly 300 according to an embodiment of the present invention during radial movement is shown. The small opening 312 of the housing 302 is positioned between the nut 326 and the disc structure 324 so that the sliding base 304 cannot move in the y direction. Specifically, the diameter of the small opening 312 of the housing 302 is slightly smaller than the diameter of the nut 326 and the diameter of the disc structure 324. In addition, there is a space 350 between the edge 314 of the small opening 312 and the sliding base 304 so that the sliding base 304 can move in the x direction and the z direction. That is, the sliding base 304 can move freely within the small opening 312 in the x-z plane. Therefore, the coupling assembly 300 can provide radial movement by 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 during angular movement is shown. Figure 19A The coupling assembly 300 is shown in a stationary position (i.e., the central position). The tapered portion 332 of the inner channel 330 tapers from the first end 320 towards the disc structure 324. The inlet valve 306 can pivot at the narrowest part of the tapered portion 332 by a certain number of degrees in angular movement. Therefore, the inlet valve 306 can rotate by using the narrowest part of the tapered portion 332 as a pivot point.

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

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

[0136] Refer to Figure 21C . The coupling assembly 400 includes a housing 402, a sliding base 404, an inlet valve 406, and an outlet valve 408. Compared with Figures 16A to 16CThe coupling assembly 300 shown has a narrow dimension of the housing 402 in the x direction and is suitable for a compact design of the cooling system. 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 has a groove 418. The groove 418 is located on the inner surface of the housing 402 and is close to the small opening 412.

[0137] The sliding base 404 is positioned within the groove 418 of the housing 402. The first end 420 of the sliding base 404 is inserted into the small opening 412 of the housing 402, and the 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 disk structure 424 having a recess 434 is positioned within the groove 418. A nut 426 is disposed at the first end 420 of the sliding base 404 such that the small opening 412 of the housing 402 is positioned between the nut 426 and the disk structure 424. Thus, 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 tapered portion 432. The tapered portion 432 tapers from the first end 420 towards the disk structure 424 and is connected 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 is inserted into the outlet valve 408 located at the second end 422 of the sliding base 304 so that the cooling fluid can flow through. An O-ring 436 is positioned at the connection between the inlet valve 406 and the outlet valve 408 to prevent leakage of the cooling fluid. An axial spring 438 is disposed within the recess 434 of the disk structure 424 and is sleeved on 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. Thus, the axial spring 438 cannot slide out of the inlet valve 406. The inlet valve 406 is used to receive a quick-connect fitting 446. The quick-connect configuration can be adopted in a wide range of applications and can improve the efficiency of the coupling assembly 400 during the assembly and disassembly processes.

[0139] The coupling assembly 400 can provide axial movement, radial movement, and angular movement of the inlet valve 406 to reduce the mechanical stress of the joint during the assembly and disassembly processes. Figures 22A to 24C Illustrates various different movements of the coupling assembly 400.

[0140] Figures 22A to 22B Illustrates a cross-sectional view of the coupling assembly 400 according to an embodiment of the present invention when moving axially. Figure 22AThe coupling assembly 400 is shown in a stationary position. Among them, the axial spring 438 is in a decompressed state. When the inlet valve 406 is pushed in 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 will decompress to reset the inlet valve 406 to the stationary position. Therefore, the coupling assembly 400 can provide axial movement in the +y direction by using the axial spring 438.

[0141] Figures 23A to 23B A cross-sectional view of the coupling assembly 400 according to an embodiment of the present invention during radial movement is shown. The small opening 412 of the housing 402 is positioned between the nut 426 and the disc 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 disc structure 424. In addition, there is a space 450 between the edge 414 of the small opening 412 and the sliding base 404 to allow the sliding base 404 to move in the x and z directions. That is, the sliding base 404 can move freely within the small opening 412 in the x-z plane. Therefore, the coupling assembly 400 can provide radial movement by using the small opening 412 of the housing 402. Compared with the coupling assembly 300, 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 the coupling assembly 400 is smaller than that of the coupling assembly 300, making the coupling assembly 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 during angular movement is shown. Figure 24A The coupling assembly 400 is in a stationary position, i.e., the central position. The tapered portion 432 of the inner channel 430 tapers from the disc structure 424 towards the first end 420. The inlet valve 406 can pivot at the narrowest part of the tapered portion 432 by a certain number of degrees. That is, the inlet valve 406 can rotate by using the narrowest part of the tapered portion 432 as a pivot point.
