Description

Technical Field

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

[0002] Gradient amplifiers are key components in medical imaging equipment. They are used to generate gradient magnetic fields in magnetic resonance imaging systems. Gradient amplifiers can amplify the small current signal of the gradient control unit to thousands of amperes of current sufficient to drive the gradient coil, achieving accurate slice selection, frequency encoding and decoding, which is crucial to improving imaging quality.

[0003] At present, due to the high output power of the gradient amplifier, a water cooling system is usually used for heat dissipation when the gradient amplifier is in use. The water cooling system consists of a water pump, a radiator, a water inlet pipe, a water outlet pipe and multiple water cooling plates, one end of each of which is connected to the water inlet pipe in turn, and the other end of each of which is connected to the water outlet pipe in turn. The water pump drives the cooling medium to flow from the water inlet pipe into the multiple water cooling plates, and the heat emitted by the gradient amplifier is transferred to the cooling medium through the water cooling plate. The heated cooling medium then flows out of the water outlet pipe. After absorbing the heat, the cooling medium is dissipated by the radiator and then supplied to the water inlet pipe by the water pump again.

[0004] When the water inlet pipe or the water outlet pipe fails, the water inlet pipe or the water outlet pipe needs to be disassembled. Since multiple water cooling plates are connected to the water inlet pipe and the water outlet pipe, the connection between the water inlet pipe or the water outlet pipe and the multiple water cooling plates needs to be disassembled before the water inlet pipe or the water outlet pipe can be disassembled.

[0032] Reference Figure 2 and Figure 3The water pipe assembly 3 includes a main water pipe 31, a water dividing block 32 and four auxiliary water pipes 33. A main channel 5 is provided in the middle of the top wall of the water dividing block 32, and four auxiliary channels 6 are provided in the middle of the bottom wall of the water dividing block 32, and the four auxiliary channels 6 are all connected to the main channel 5. The water dividing block 32 is located at the main channel 5 and is threadedly detachably mounted with a quick connector 7. One end of the main water pipe 31 is connected to the quick connector 7, and the other end of the main water pipe 31 is connected to the water pump 1 or the radiator 2. The quick connector 7 can be removed from the water dividing block 32 by rotating it, so as to facilitate the quick disassembly and assembly of the main water pipe 31.

[0033] The water-dividing block 32 is located at each secondary channel 6 and is detachably installed with a connector 8 threaded thereon. The end of the connector 8 away from the water-dividing block 32 is formed with a first pagoda head 9. One end of the secondary water pipe 33 is sleeved on the pagoda head. The outer side of the secondary water pipe 33 located at the end of the first pagoda head 9 is sleeved with a first crimping copper sleeve 10. In the present application, the secondary water pipe 33 can be selected as a rubber hose. The secondary water pipe 33 can be removed from the water-dividing block 32 by rotating the connector 8, which is convenient for quickly disassembling and assembling the secondary water pipe 33. The first crimping copper sleeve 10 presses the end of the secondary water pipe 33 onto the first pagoda head 9 of the connector 8, which increases the stability of the connection between the secondary water pipe 33 and the connector 8 on the one hand, and increases the sealing between the secondary water pipe 33 and the connector 8 on the other hand.

[0034] Reference Figure 4 , the end of the auxiliary water pipe 33 away from the connector 8 is connected to a quick-release plug 11, and a second pagoda head 12 is formed at the end of the quick-release plug 11. The second pagoda head 12 is inserted into the end of the auxiliary water pipe 33 away from the connector 8.

[0035] The implementation principle of a cooling system for a gradient amplifier in Example 1 of the present application is as follows: a water pump 1 drives a cooling medium to flow from a water inlet main water pipe 31 into four water inlet auxiliary water pipes 33, and then from the water inlet auxiliary water pipes 33 into a water cooling plate 4. The heat emitted by the gradient amplifier is transferred to the cooling medium through the water cooling plate 4. The heated cooling medium then flows from four water outlet auxiliary water pipes 33 into a water outlet main water pipe 31, and then from the water outlet main water pipe 31 into the radiator 2. The cooling medium after absorbing heat is dissipated by the radiator 2 and then supplied out again by the water pump 1. When it is necessary to repair the water inlet pipeline or the water outlet pipeline, it is only necessary to disassemble the main water pipe 31 or a single auxiliary water pipe 33 for targeted repair, thereby facilitating the repair of the cooling system.

Four first transmission components 22 are installed on the top wall of the lifting plate 19. The four first transmission components 22 are respectively connected to the four first gears 21 and the first sleeve 14.

[0038] When the lifting plate 19 moves upward, the lifting plate 19 drives the first gear 21 to move on the first rack 20, so that the first gear 21 rotates, and the first gear 21 then drives the first sleeve 14 to rotate through the first transmission assembly 22, so that the top end of the first sleeve 14 rotates away from the middle of the lifting plate 19.

[0045] During the rotation of the first sleeve 14 and the second sleeve 15, the middle part of the auxiliary water pipe 33 will bend outward, so as to adjust the distance from one end of the auxiliary water pipe 33 away from the water distribution block 32 to the water distribution block 32, so that the auxiliary water pipe 33 can be suitable for connecting the water cooling plates 4 at different positions.

[0046] Reference Figure 6 and Fig.10 Eight locking components 26 for locking the lifting plate 19 are installed along the circumference of the fixed plate 17 and the lifting plate 19. The locking components 26 include a lifting rod 261, a first non-return rack 262, a second non-return rack 263, a first elastic member 264 and a pressing block 265.

[0048] When the lifting plate 19 moves upward, the lifting plate 19 drives the lifting rod 261 to move upward, the second check rack 263 will not clamp the first check rack 262, and the lifting rod 261 drives the first check rack 262 to move through the second check rack 263, so that the lifting of the lifting plate 19 is not affected. When the lifting rod 261 stops moving, the first elastic member 264 pushes the second check rack 263 to clamp on the first check rack 262, so that the lifting plate 19 can be locked, so that the lifting plate 19 will not move downward. When the lifting plate 19 needs to be lowered and reset, the pressing block 265 is pressed, and the pressing block 265 drives the second check rack 263 to move away from the first check rack 262, thereby releasing the lock on the lifting rod 261, and the lifting plate 19 can be lowered and reset.

When the four plate bodies are spliced ​​together, the connecting block 28 of one plate body is inserted into the connecting groove 29 of another adjacent plate body. When the connecting blocks 28 in the four plate bodies are all inserted into the connecting grooves 29 of the adjacent plate bodies, the fixed plate 17 and the lifting plate 19 can be formed.

[0050] The sliding connecting block 28 can be used to combine and split multiple plates. When the multiple plates are combined, the four auxiliary water pipes 33 can be bent synchronously. When the multiple plates are split, the four auxiliary water pipes 33 can be bent individually, thereby further improving the applicability of the bending of the auxiliary water pipes 33.

[0051] Reference Figure 8, the two first drive blocks 225 are slidably installed along the axial direction of the second synchronous wheel 224 in one end of the two second synchronous wheels 224 where the rotating shafts are close to each other, and a second elastic member 30 is installed in the rotating shaft of the second synchronous wheel 224, and the second elastic member 30 pushes the first drive block 225 to insert into the slot of the first sleeve 14. In the present application, the second elastic member 30 can be selected as a spring. A pull rod 34 is fixedly installed at one end of the first drive block 225 away from the first sleeve 14, and the end of the pull rod 34 away from the first drive block 225 slides through the rotating shaft of the second synchronous wheel 224. The installation structure of the second drive block is the same as that of the first drive block 225 (not shown in the figure).

[0052] When it is necessary to disassemble and repair a single auxiliary water pipe 33, first disassemble the four plates, remove the fixed connection between the plates and the support rods 16, remove the auxiliary water pipe 33 from the water distribution block 32, and then use the pull rod 34 to pull the first drive block 225 and the second drive block to move, so that the first drive block 225 and the second drive block are disengaged from the slots of the first sleeve 14 and the second sleeve 15, and the auxiliary water pipe 33 can be separated from the plate, thereby facilitating the disassembly and repair of the auxiliary water pipe 33.

[0053] The implementation principle of Example 2 of the present application is as follows: when the lifting plate 19 moves upward, the lifting plate 19 drives the first gear 21 to move on the first rack 20, so that the first gear 21 rotates, and the first gear 21 then drives the first sleeve 14 to rotate through the first transmission assembly 22, so that the top end of the first sleeve 14 rotates away from the middle of the lifting plate 19. The lifting plate 19 drives the second rack 23 to move upward, so that the second gear 24 rotates, and the second gear 24 then drives the second sleeve 15 to rotate through the second transmission assembly 25, so that the bottom end of the second sleeve 15 rotates away from the middle of the fixed plate 17. During the rotation of the first sleeve 14 and the second sleeve 15, the middle part of the auxiliary water pipe 33 will be driven to bend outward, so that the distance from one end of the auxiliary water pipe 33 away from the water distribution block 32 to the water distribution block 32 can be adjusted, so that the auxiliary water pipe 33 can be suitable for connecting the water-cooled plates 4 at different positions.

For those skilled in the art, the present disclosure may have various modifications and variations. 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.
