Description

Technical Field

[0001] The utility model relates to the technical field of power supplies, and particularly relates to a heat dissipation structure for a high-power power supply. Background Art

[0002] When a high-power power supply supplies power, the current and voltage are relatively large, so the overall heat generated by the power supply is also relatively large. In order to protect the power supply, it is necessary to dissipate the heat of the power supply through a heat dissipation structure.

[0003] A heat dissipation structure for a high-power power supply disclosed in Chinese Patent CN220087804U. In this heat dissipation structure for a high-power power supply, the heat dissipation plates on the upper and lower surfaces of the power supply absorb heat. The heat dissipation plates absorb heat through the cooling liquid circulating inside the cooling cavity and then dissipate the heat. The cooperation of the heat dissipation grooves increases the heat dissipation area, and the graphene heat dissipation layer improves the heat dissipation effect, enabling the heat absorbed by the heat dissipation plates to be quickly dissipated, maintaining the heat absorption effect of the heat dissipation plates, and thus being able to quickly dissipate the heat of the power supply. However, while solving the problems, this heat dissipation structure for a high-power power supply has the following defects:

[0004] The heat dissipation plates are connected to the inner wall of the installation frame through damping shock absorbers. At the same time, the two heat dissipation plates clamp the power supply through bolts. Therefore, when the power supply is damaged and needs to be repaired, it is not easy to disassemble the power supply from the inside of the installation frame. Summary of the Utility Model

[0024] As Figures 1-4 shown, a heat dissipation structure of a high-power power supply in this embodiment includes a heat dissipation box 1. A through groove 2 is opened on one side of the heat dissipation box 1. An L-shaped plate 3 is movably connected inside the through groove 2. A power supply body 4 is arranged on the top of the L-shaped plate 3. The power supply body 4 can be directly placed inside the L-shaped plate 3. At the same time, the L-shaped plate 3 can drive the power supply body 4 to move into the heat dissipation box 1 through the through groove 2. One side of the inner wall of the L-shaped plate 3 is fixedly connected with a moving frame 5. A receiving groove 6 is opened at one end of the moving frame 5. A guiding column 7 is movably connected inside the receiving groove 6. One end of the guiding column 7 is fixedly connected with a moving column 30. One end of the moving column 30 is fixedly connected with a baffle 8. By pulling the baffle 8, the guiding column 7 can be moved inside the receiving groove 6, so that it is more convenient to place the power supply body 4 on the L-shaped plate 3. The moving frame 5 and the moving column 30 can limit both sides of the power supply body 4. At the same time, the setting of the moving frame 5 makes there be a moving distance between the power supply body 4 and one side of the inner wall of the L-shaped plate 3 after the fixation of the power supply body is completed. A connecting frame 9 is connected to one side of the inner wall of the L-shaped plate 3. A connecting column 31 is fixedly connected to the back of the baffle 8. After moving the L-shaped plate 3 into the heat dissipation box 1, continue to push the baffle 8 and make the baffle 8 move into the through groove 2. At the same time, one end of the moving frame 5 and the moving column 30 are in contact with each other, and one end of the connecting frame 9 and the connecting column 31 are in contact with each other. Fixing holes 10 are opened at the tops of the connecting frame 9 and the connecting column 31. A fixing column 11 is movably connected inside the fixing hole 10. The top end of the fixing column 11 is fixedly connected with a pressing plate 12. A screw rod 13 is rotatably connected to the top of the pressing plate 12. The bottom end of the screw rod 13 is rotatably connected to the pressing plate 12 through a bearing. The screw rod 13 is threadedly connected to the heat dissipation box 1. By rotating the screw rod 13 and making the screw rod 13 drive the pressing plate 12 to move downward, at the same time, the pressing plate 12 drives a plurality of fixing columns 11 to move into the corresponding fixing holes 10 and makes the connecting frame 9 and the connecting column 31 connected together, so that the L-shaped plate 3 and the baffle 8 will not move out of the heat dissipation box 1.

[0025] Embodiment 1: A limiting groove 14 is formed in the inner wall of the storage groove 6. A limiting block 15 is movably connected inside the limiting groove 14. The limiting block 15 is fixedly connected to the guiding column 7. When the guiding column 7 moves inside the storage groove 6, the guiding column 7 can drive the limiting block 15 to slide inside the limiting groove 14.

[0026] Embodiment 2: A support column 16 is fixedly connected to the top of the L-shaped plate 3. A roller 17 is arranged at the top of the support column 16. When placing the power supply body 4, the power supply body 4 can be directly placed on the roller 17 on the support column 16. When one end of the connecting frame 9 is in contact with one end of the connecting column 31, the baffle 8 can push the power supply body 4 and cause the power supply body 4 to drive the roller 17 to rotate. At the same time, the back surface of the power supply body 4 is in contact with the inner walls of the moving frame 5 and the connecting frame 9. An extrusion column 18 is fixedly connected to the bottom of the extrusion plate 12. The extrusion plate 12 can drive the extrusion column 18 to move downward and make the extrusion column 18 contact the top of the power supply body 4.

[0027] Embodiment 3: A rotating disk 19 is fixedly connected to the top of the screw rod 13. A shielding ring 20 is fixedly connected to the top of the heat dissipation box 1. The rotating disk 19 is arranged inside the shielding ring 20. The screw rod 13 can be rotated through the rotating disk 19. At the same time, the shielding ring 20 can shield the screw rod 13, and the shielding ring 20 is arranged relatively large, so that the rotation of the rotating disk 19 will not be affected.

[0028] Embodiment 4: A pulling frame 21 is fixedly connected to the front surface of the baffle 8. A connecting groove 22 is formed in the front surface of the baffle 8. The baffle 8 can be pulled through the pulling frame 21. After the baffle 8 is in contact with the front surface of the power supply body 4, the part where the power supply body 4 is connected to the external device is directly inside the connecting groove 22.

[0029] Embodiment 5: A cold air box 23 is fixedly connected to one side of the heat dissipation box 1. A heat dissipation groove 24 is formed in one side of the cold air box 23. The heat dissipation groove 24 penetrates through the cold air box 23 and the heat dissipation box 1. Airflow can flow from the inside of the heat dissipation groove 24 on one side of the cold air box 23 into the heat dissipation box 1. At the same time, the airflow can drive the heat on the power supply body 4 to flow out from the heat dissipation groove 24 on the other side of the heat dissipation box 1.

[0030] Embodiment 6: An air plate 25 is fixedly installed inside the cold air box 23. An installation groove 26 is formed in one side of the air plate 25. A fan 27 is fixedly installed inside the installation groove 26. The fan 27 can extract external airflow through the heat dissipation groove 24 on the cold air box 23.

[0031] Embodiment Column 7: A cooling pipe 28 is arranged inside the cold air box 23. Both ends of the cooling pipe 28 penetrate through the cold air box 23 and are fixedly connected to a chiller 29. The chiller 29 is fixedly installed on the top of the cold air box 23. Cooling water is arranged inside the cooling pipe 28. With the assistance of the chiller 29, the cooling water can flow inside the cooling pipe 28 and can always maintain a low temperature state. At the same time, the cooling pipe 28 is arranged in a winding manner up and down and has multiple layers, so that the air flow can be better cooled after passing through the cooling pipe 28.

[0032] The working principle of the present utility model is as follows: When in use, the chiller 29 transports cooling water into the cooling pipe 28 and makes the cooling water flow inside the cooling pipe 28. At the same time, the fan 27 rotates and extracts the external air flow through the heat dissipation slot 24 on one side of the cold air box 23. The temperature of the extracted air flow can be reduced when passing through the cooling pipe 28. When the air flow with reduced temperature flows into the inside of the heat dissipation box 1, it can push the power supply body 4. At the same time, the air flow can directly flow past the bottom, top and front of the power supply body 4. After the air flow flows past, the heat on the power supply body 4 can be taken away and flow out of the inside of the heat dissipation box 1 through the heat dissipation slot 24 on the other side of the heat dissipation box 1.

[0033] When the power supply body 4 is damaged and needs to be repaired, directly rotate the screw rod 13 and make the screw rod 13 drive the extrusion column 18 to move upward through the extrusion plate 12. The fixed column 11 also moves out of the fixing holes 10 on the connecting frame 9 and the connecting column 31. Then, pull the baffle 8 through the pulling frame 21. The baffle 8 drives the guide column 7 to move inside the receiving groove 6 through the moving column 30. When the limiting block 15 contacts the inner wall of the limiting groove 14, the L-shaped plate drives the power supply body 4 to move together with the baffle 8 and move out of the inside of the heat dissipation box 1 through the through groove 2. At this time, the distance between the baffle 8 and the L-shaped plate 3 becomes larger. At the same time, there is a distance between the power supply body 4 and the L-shaped plate 3 under the support of the support column 16, so that the operator can directly carry the power supply body 4 off the L-shaped plate 3.

[0034] Compared with the prior art, the present utility model has the following beneficial effects compared with the prior art:

[0035] 1. When the power supply body 4 needs to be repaired due to damage, directly rotate the screw rod 13 so that the screw rod 13 drives the extrusion plate 12 to move upward. At the same time, the extrusion plate 12 drives the fixed column 11 to move out of the inside of the fixing hole 10. At this time, directly pull the baffle plate 8 so that the baffle plate 8 drives the guide column 7 to move inside the storage groove 6 through the moving column 30. When the guide column 7 cannot move, pull the moving frame 5 and make the L-shaped plate 3 drive the power supply body 4 to move out of the inside of the heat dissipation box 1. Since the distance between the L-shaped plate 3 and the baffle plate 8 can become larger with the assistance of the storage groove 6 and the guide column 7, it is also relatively convenient to take out the power supply body 4 from the L-shaped plate 3. To sum up, when taking out the power supply body 4 from the inside of the heat dissipation box 1, directly rotate the screw rod 13, and then pull the L-shaped plate 3 and the power supply body 4 out of the inside of the heat dissipation box 1 through the baffle plate 8, and the operation is relatively convenient.

[0036] 2. Driven by the chiller 29, the cooling water can flow inside the cooling pipe 28, and at the same time, the cooling water can always remain at a low temperature. When the fan 27 on the air plate 25 extracts the air flow outside the cold air box 23 through the heat dissipation slot 24, the temperature of the extracted air flow can become lower when it passes through the cooling pipe 28. The air flow with a lower temperature can be directly blown through the heat dissipation slot 24 on the heat dissipation box 1 to blow the power supply body 4 inside the heat dissipation box 1 under the blowing of the fan 27. At the same time, the settings of the support column 16 and the extrusion column 18 make there be a certain distance between the bottom and the top of the power supply body 4 and the L-shaped plate 3 and the extrusion plate 12, so that the air flow with a lower temperature can directly flow past the top and bottom of the power supply body 4 and take away the heat generated by the power supply body 4. Then, the heat can flow out through the heat dissipation slot 24 on the other side under the blowing of the air flow. At the same time, the air flow with a lower temperature can also cool the power supply body 4 itself to a certain extent when passing through the power supply body 4. To sum up, the settings of the heat dissipation slot 24, the fan 27, the cooling pipe 28, the chiller 29, the support column 16 and the extrusion column 18 improve the heat dissipation effect when dissipating heat from the power supply body 4.
