Description

Technical Field

[0001] This application relates to the field of cooling technology, and in particular to a cooling system for a gradient amplifier. Background Art

[0002] The gradient amplifier is a key component in medical imaging equipment and is used to generate a gradient magnetic field in a magnetic resonance imaging system. The gradient amplifier can amplify a small current signal from a gradient control unit to a current of thousands of amperes sufficient to drive a gradient coil, achieving precise slice selection, frequency encoding, and decoding, which is crucial for improving imaging quality.

[0003] Currently, due to the high output power of the gradient amplifier, a cooling system is usually used for heat dissipation when the gradient amplifier is in use. The cooling system consists of a water chiller, an inlet pipe, an outlet pipe, and multiple water cooling plates. Both the inlet pipe and the outlet pipe are connected to the water chiller. One end of the multiple water cooling plates is sequentially connected to the inlet pipe, and the other end is sequentially connected to the outlet pipe. The water chiller drives the cooling medium to flow into the multiple water cooling plates from the inlet pipe. The heat dissipated by the gradient amplifier is transferred to the cooling medium through the water cooling plates, and the heated cooling medium flows back to the outlet pipe and then back to the water chiller through the outlet pipe.

[0004] When repairing the cooling system, it is necessary to disassemble the inlet pipe and the outlet pipe from the water chiller. When the inlet pipe and the outlet pipe are disassembled, the cooling medium remaining in the pipeline is likely to leak out. If the leaked cooling medium flows into the gradient amplifier, it will damage the equipment. Summary of the Invention

Detailed implementation manners

[0044] The following further elaborates on the present application in conjunction with the attached Figures 1-12 drawings.

[0045] Embodiment 1:

[0046] An embodiment of the present application discloses a cooling system for a gradient amplifier.

[0047] Referring to Figure 1 and Figure 2 , a cooling system for a gradient amplifier includes a water chiller 1, a mounting bracket 2, two water pipe assemblies 3, and five water cooling plates 4. The two water pipe assemblies 3 are respectively an inlet water pipe assembly and an outlet water pipe assembly. One end of the two water pipe assemblies 3 is connected with a connecting pipe 39, and the ends of the two connecting pipes 39 far from the water pipe assemblies 3 are respectively connected to the inlet end and the outlet end of the water chiller 1. The ends of the inlet water pipe assembly far from the connecting pipe 39 are respectively connected to the water inlets of the plurality of water cooling plates 4, and the ends of the outlet water pipe assembly far from the connecting pipe 39 are respectively connected to the water outlets of the plurality of water cooling plates 4.

[0048] The water chiller 1 supplies a cooling medium into the inlet water pipe assembly through the connecting pipe 39. The cooling medium in the inlet water pipe assembly flows into the plurality of water cooling plates 4 from the water inlets of the water cooling plates 4. The heat dissipated by the gradient amplifier is transferred to the cooling medium through the water cooling plates 4. The heated cooling medium flows into the outlet water pipe assembly from the water outlets of the water cooling plates 4, and the cooling medium in the outlet water pipe assembly then flows back to the water chiller 1 through the connecting pipe 39, thereby realizing the circulating cooling of the high-intensity gradient amplifier.

[0049] Referring to Figure 3 and Figure 4 , the mounting bracket 2 is fixedly installed on the outer frame of the gradient amplifier housing by bolts, and two connecting joints 7 are detachably and fixedly installed on the mounting bracket 2. An external thread is formed at the top of one connecting joint 7, and an internal thread is formed at the top of the other connecting joint 7. The bottom ends of the two connecting pipes 39 are respectively installed on the two connecting joints 7 through an internal thread rotary joint 12 and an external thread rotary joint 12. The bottom end of the connecting joint 7 passes through the mounting bracket 2, an external thread is formed at the bottom end of the connecting joint 7, and a first nut 11 is threadedly installed at the bottom end of the connecting joint 7. Rotating the first nut 11 can fixedly install the connecting joint 7 on the mounting bracket 2.

[0050] Referring to Figure 1 , Figure 3 and Figure 5 , a water pipe assembly 3 includes a main water pipe 31, a branch water pipe 32, and five sub-water pipes 33. The top end of the main water pipe 31 is fixedly sleeved on the bottom end of the connecting joint 7 through a clamp, and the bottom end of the main water pipe 31 is fixedly sleeved on the top end of the branch water pipe 32 through a clamp. Four water distribution ports 38 are fixedly installed at equal intervals along the length direction of the side wall of the branch water pipe 32, and a fifth water distribution port 38 is fixedly installed at the bottom end of the branch water pipe 32 far from the main water pipe 31. The water distribution ports 38 are communicated with the inner cavity of the branch water pipe 32.

[0051] The five auxiliary water pipes 33 are respectively sleeved on the five water distribution ports 38 through clamping rings, and quick-connect joints 8 are fixedly installed at the ends of the five auxiliary water pipes 33 far from the water distribution pipe 32 through clamping rings. The five quick-connect joints 8 on the inlet water pipe assembly are respectively connected to the inlets of the five water-cooled plates 4 through pipes, and the five quick-connect joints 8 on the outlet water pipe assembly are respectively connected to the outlets of the five water-cooled plates 4 through pipes.

[0052] The cooling medium enters the main water pipe 31 of the inlet water pipe assembly from the connecting pipe 39, then enters the water distribution pipe 32 from the main water pipe 31. The cooling medium in the water distribution pipe 32 enters the five auxiliary water pipes 33 through the five water distribution ports 38, and then enters the water-cooled plates 4 from the auxiliary water pipes 33, so that the cooling medium in the main water pipe 31 can be shunted, making the cooling medium flowing through the five water-cooled plates 4 more uniform. The cooling medium in the water-cooled plates 4 flows back to the water distribution pipe 32 from the five auxiliary water pipes 33 of the outlet water pipe assembly, then flows back to the main water pipe 31 from the water distribution pipe 32, and finally flows back to the water-cooling machine 1 from the connecting pipe 39.

[0053] Refer to Figure 3 and Figure 4 As shown in, a water storage tank 5 is formed by the middle part of the mounting bracket 2 being recessed downward. Both connecting joints 7 are installed in the water storage tank 5 of the mounting bracket 2. A drain port 9 is fixedly installed on the bottom wall of the mounting bracket 2, and the drain port 9 communicates with the water storage tank 5. A drain pipe 6 is installed at the bottom of the mounting bracket 2. The top end of the drain pipe 6 is sleeved on the drain port 9, and a fixing clamp 10 is sleeved on the outer side wall of the top end of the drain pipe 6. The fixing clamp 10 fixes the drain pipe 6 on the drain port 9, and the drain pipe 6 communicates with the water storage tank 5 through the drain port 9.

[0054] When repairing the cooling system, when the connection between the connecting pipe 39 and the connecting joint 7 is disassembled, the cooling medium remaining in the pipeline will flow into the water storage tank 5 of the mounting bracket 2, and the cooling medium is discharged from the drain pipe 6 through the drain port 9, so that the leaked cooling medium will not damage the gradient amplifier. Using the fixing clamp 10 to fixedly sleeve the top end of the drain pipe 6 on the drain port 9 makes it not easy for the connection between the drain pipe 6 and the mounting bracket 2 to leak. At the same time, disassembling the fixing clamp 10 can disassemble and remove the drain pipe 6 from the drain port 9, which is convenient for repairing and replacing the drain pipe 6.

[0055] The implementation principle of the cooling system for a gradient amplifier in an embodiment of the present application is as follows: The cooling medium enters the main water pipe 31 of the water inlet pipe assembly from the connecting pipe 39, and then enters the branch water pipe 32 from the main water pipe 31. The cooling medium in the branch water pipe 32 enters the five secondary water pipes 33 through five water distribution ports 38, and then enters the water-cooled plate 4 from the secondary water pipes 33. The heat dissipated by the gradient amplifier is transferred to the cooling medium through the water-cooled plate 4. The cooling medium in the water-cooled plate 4 flows back from the five secondary water pipes 33 of the water outlet pipe assembly to the branch water pipe 32, then flows back from the branch water pipe 32 to the main water pipe 31, and finally flows back to the water cooler 1 from the connecting pipe 39, thereby realizing the circulating cooling of the high-intensity gradient amplifier. When repairing the cooling system, the connection between the connecting pipe 39 and the connecting joint 7 is disassembled, and the cooling medium remaining in the pipeline will flow into the water storage tank 5 of the mounting bracket 2. The cooling medium is discharged from the water storage tank 5 through the drain port 9 and the drain pipe 6, so that the leaked cooling medium will not damage the gradient amplifier.

[0056] Embodiment 2:

[0057] Referring to Figure 6 and Figure 7 In this embodiment, the difference from Embodiment 1 is that a water shield 14 is installed on the mounting bracket 2. The bottom of the water shield 14 is open, and a sealing ring 34 is embedded and installed on the bottom wall of the water shield 14. The water shield 14 is installed in the water storage tank 5, the sealing ring 34 abuts against the bottom wall of the water storage tank 5, and the water shield 14 covers the two rotary joints 12. A locking assembly 17 is installed in the water shield 14. The locking assembly 17 fixedly installs the water shield 14 in the mounting bracket 2. An unlocking assembly 18 is installed in the water shield 14. The unlocking assembly 18 unlocks the locking assembly 17. By using the locking assembly 17 and the unlocking assembly 18, the water shield 14 can be detachably and fixedly installed on the mounting bracket 2.

[0058] An observation window 13 is installed on the side wall of the water shield 14. A connecting sleeve 15 and a second nut 16 are sleeved on each connecting pipe 39. The bottom end of the connecting sleeve 15 is fixedly connected to the rotary joint 12. The connecting sleeve 15 slidably passes through the top wall of the water shield 14, and the second nut 16 is fixedly connected to the top end of the connecting sleeve 15.

[0059] Rotate the second nut 16. The second nut 16 drives the connecting sleeve 15 to rotate, and the connecting sleeve 15 drives the rotary joint 12 to rotate, so that the rotary joint 12 is separated from the connecting joint 7. When the leakage of the cooling medium in the pipeline is large, the water shield 14 can cover the water storage tank 5, so that the cooling medium will not overflow from the water storage tank 5. Observe the situation in the water storage tank 5 through the observation window 13. After all the cooling medium in the water storage tank 5 is discharged, use the unlocking assembly 18 to unlock the locking assembly 17, and then the water shield 14 can be removed from the mounting bracket 2, so that the connecting pipe 39 and the connecting joint 7 can be disassembled.

[0060] Referring to Figure 7 、 Figure 8 and Figure 9 Specifically, the locking assembly 17 includes three driving gears 173, six locking blocks 171, a first rack 172 and an elastic member 174. A support rod 40 is fixedly installed in the middle of the length direction of the water shield 14. The three driving gears 173 are rotatably installed at the bottom of the support rod 40 along the length direction of the support rod 40. The six first racks 172 are slidably installed at the bottom of the water shield 14. Two first racks 172 are installed along the width direction of the water shield 14, and four first racks 172 are installed along the length direction of the water shield 14. Every two first racks 172 are engaged with one driving gear 173 and are located on both sides of the synchronous rack.

[0061] The six locking blocks 171 are fixedly installed at the ends of the six first racks 172 close to the outer side of the water shield 14. The six locking blocks 171 respectively slide through the peripheral side walls of the water shield 14. Six guide frames 41 are fixedly installed on the inner peripheral side wall of the water shield 14. The ends of the six first racks 172 away from the locking blocks 171 are respectively slidably installed in the six guide frames 41.

[0062] Six moving seats 35 are fixedly installed on the inner side walls around the water shield 14. The six locking blocks 171 are respectively slidably installed in the six moving seats 35. A push plate 36 is fixedly installed on each locking block 171. The push plate 36 is located inside the water shield 14. The six elastic members 174 are respectively sleeved on the six locking blocks 171. In this application, the elastic member 174 can be selected as a spring, and one end of the elastic member 174 abuts against the inner wall of the water shield 14, and the other end abuts against the moving seat 35.

[0063] Six locking grooves 19 are opened on the peripheral side walls of the installation bracket 2 located around the water storage tank 5. When installing the water shield 14, the water shield 14 is placed into the water storage tank 5 of the installation bracket 2. The inner wall of the installation bracket 2 pushes the six locking blocks 171 to slide into the water shield 14. The locking blocks 171 drive the push plates 36 to squeeze the elastic members 174, so that the elastic members 174 contract and deform. When the water shield 14 moves into the water storage tank 5 and the sealing ring 34 at the bottom of the water shield 14 abuts tightly against the bottom wall of the water storage tank 5, the elastic members 174 drive the locking blocks 171 to move and insert into the locking grooves 19 through the push plates 36, so that the water shield 14 can be fixed in the installation bracket 2.

[0064] The unlocking assembly 18 includes a second rack 181 and a button 182. The second rack 181 is slidably installed in the water baffle 14. Above the support rod 40, three synchronous gears 37 are rotatably installed. Three driving gears 173 are coaxially installed with the three synchronous gears 37. The three synchronous gears 37 are located at the same height, and the three synchronous gears 37 are engaged with the second rack 181. The button 182 is fixedly installed at the end of the second rack 181, and the button 182 slides through the water baffle 14 along the length direction of the second rack 181.

[0065] When the cooling medium in the water storage tank 5 is completely discharged, press the button 182. The button 182 drives the second rack 181 to slide in the water baffle 14. The second rack 181 drives the three synchronous gears 37 to rotate. The three synchronous gears 37 drive the three driving gears 173 to rotate synchronously. The three driving gears 173 then drive the six first racks 172 to move towards the inside of the water baffle 14. The six first racks 172 then drive the six lock blocks 171 to slide out of the six lock grooves 19, thereby unlocking the locking assembly 17 and enabling the water baffle 14 to be removed from the mounting bracket 2.

[0066] Refer to Figure 8 and Figure 10 As shown in, a slide bar 20 is slidably installed in the water baffle 14. The slide bar 20 is parallel to the second rack 181. A knob 23 is rotatably installed at the end of the slide bar 20. A rotating seat 42 is fixedly installed in the side wall of the water baffle 14. A through hole 25 is formed in the rotating seat 42. The knob 23 is slidably installed in the through hole 25. An elastic reset member 24 is installed at the rotational connection between the slide bar 20 and the knob 23. In this application, the elastic reset member 24 can be selected as a torsion spring. After rotating the knob 23, the elastic reset member 24 can drive the knob 23 to rotate in the reverse direction and reset.

[0067] On the inner wall of the water baffle 14 at the position of the through hole 25, a rotating groove 27, a moving groove 28 and a positioning groove 29 are formed in sequence and communicated with each other. The rotating groove 27 is formed along the circumferential direction of the knob 23. The moving groove 28 is formed along the axial direction of the knob 23. The positioning groove 29 is formed along the circumferential direction of the knob 23. The rotating groove 27 is located at one end of the moving groove 28 close to the outside of the water baffle 14. The positioning groove 29 is located at one end of the moving groove 28 close to the inside of the water baffle 14. And the rotating groove 27 and the positioning groove 29 are located on the same side in the width direction of the moving groove 28. A clamping block 26 is fixedly installed on the side wall of the knob 23. The clamping block 26 is slidably installed in the rotating groove 27, the moving groove 28 and the positioning groove 29.

[0068] A first stop block 21 is fixedly installed on the side wall of the second rack 181 close to the slide bar 20. A second stop block 22 is fixedly installed on the side wall of the slide bar 20 close to the second rack 181. The second stop block 22 is located on the side of the first stop block 21 away from the knob 23, and the second stop block 22 abuts against the first stop block 21.

[0069] When the water baffle 14 is installed on the mounting bracket 2, the clamping block 26 is located in the rotating groove 27. The clamping block 26 limits the knob 23 through the rotating groove 27, so that the knob 23 cannot slide in the through hole 25. The knob 23 then limits the second stopper 22 through the sliding rod 20, and the second stopper 22 limits the second rack 181 through the first stopper 21, so that the second rack 181 cannot move, preventing the unlocking assembly 18 from accidentally causing the water baffle 14 to disengage from the mounting bracket 2.

[0070] When it is necessary to unlock the locking assembly 17, first rotate the knob 23 in the direction close to the moving groove 28. The knob 23 drives the elastic reset member 24 to deform. The knob 23 drives the clamping block 26 to slide from the rotating groove 27 into the moving groove 28, and then press the button 182. The button 182 drives the clamping block 26 to move in the moving groove 28 in the direction close to the positioning groove 29. At the same time, the button 182 drives the second stopper 22 to move through the sliding rod 20. The second stopper 22 moves and separates from the first stopper 21, enabling the second rack 181 to slide and unlock. When the clamping block 26 moves into the positioning groove 29, the elastic reset member 24 releases its elastic potential energy and drives the knob 23 to rotate back. The knob 23 drives the clamping block 26 to move into the positioning groove 29, thereby positioning the position of the knob 23 and facilitating the unlocking assembly 18 to unlock the locking assembly 17.

[0071] The implementation principle of Embodiment 2 of this application is as follows: Rotate the second nut 16. The second nut 16 drives the connecting sleeve 15 to rotate, and the connecting sleeve 15 drives the rotary joint 12 to rotate, causing the rotary joint 12 to separate from the connecting joint 7. When the leakage of the cooling medium in the pipeline is relatively large, the water baffle 14 can cover the water storage tank 5, preventing the cooling medium from overflowing from the water storage tank 5. Observe the situation in the water storage tank 5 through the observation window 13. After all the cooling medium in the water storage tank 5 is drained, first rotate and press the knob 23. The knob 23 drives the second stopper 22 to move and release the limit on the second rack 181, and then press the button 182. The button 182 drives the second rack 181 to move and unlock the water baffle 14, and then the water baffle 14 can be removed from the mounting bracket 2, enabling the connecting pipe 39 and the connecting joint 7 to be disassembled.

[0072] Embodiment 3:

[0073] Refer to Figure 11 and Figure 12, The difference between this embodiment and Embodiment 2 is that the unlocking assembly 18 includes a third rack 183, a pull rope 184, a lifting frame 185, a push rod 186 and three rollers 187. The third rack 183 is slidably installed in the water baffle 14. The third rack 183 meshes with three synchronous gears 37. Four support rods 44 are fixedly installed on the side wall of the support rod 40. The third rack 183 slides on the tops of the four support rods 44. The lifting frame 185 is slidably installed in the middle of the top wall of the inner cavity of the water baffle 14 in the vertical direction, and the lifting frame 185 is located between the two connecting sleeves 15. The push rod 186 is rotatably installed at the bottom end of the lifting frame 185, and the rotation point of the push rod 186 is located in the middle of its own length direction.

[0074] All three rollers 187 are rotatably installed in the water baffle 14 through connecting rods 43. The first roller 187 is located below the lifting frame 185. The second roller 187 is located in the upper middle part of the inner side wall of the water baffle 14. The third roller 187 is located in the lower middle part of the inner wall of the water baffle 14, and the third roller 187 is located at one end of the third rack 183 in the length direction. One end of the pull rope 184 is fixedly connected to the bottom of the lifting frame 185, and the other end is fixedly connected to the end of the third rack 183 in the length direction after passing through the three rollers 187 in sequence.

[0075] Push plates 30 are fixedly sleeved on the side walls of the two connecting sleeves 15. The two push plates 30 are located below the two ends of the push rod 186. After the rotary joint 12 is separated from the connecting joint 7, pulling up the connecting pipe 39 can drive the push plate 30 to move upward. When one push plate 30 moves upward, the push plate 30 moves to abut against the push rod 186 and pushes the push rod 186 to rotate on the lifting frame 185. At this time, the lifting frame 185 will not move upward.

[0076] Pull up the two connecting pipes 39 at the same time. The two connecting pipes 39 drive the two push plates 30 to move upward through the two connecting sleeves 15. The two push plates 30 simultaneously contact the two ends of the push rod 186 and drive the push rod 186 to move upward. The push rod 186 drives the lifting frame 185 to move upward. The lifting frame 185 pulls the third rack 183 to move through the pull rope 184. The third rack 183 drives the three drive gears 173 to move through the three synchronous gears 37. The three drive gears 173 drive the six first racks 172 to move synchronously. The first racks 172 drive the lock blocks 171 to slide out of the lock grooves 19, so that the locking assembly 17 can be unlocked.

[0077] The implementation principle of Embodiment 3 of this application is as follows: When the cooling medium in the water storage tank 5 is completely drained, pull up the two connecting pipes 39 simultaneously. The two connecting pipes 39 drive the two push plates 30 to move upward. The two push plates 30 drive the push rod 186 to move upward. The push rod 186 drives the lifting frame 185 to move upward. The lifting frame 185 pulls the third rack 183 to move through the pulling rope 184. The third rack 183 drives the multiple drive gears 173 to rotate synchronously, so as to unlock the locking assembly 17.

[0078] The above are only alternative embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
