[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-7 , the utility model provides a technical solution:

[0024] A self-heating circulating centrifugal pump includes a base 1, a pump body 2, a motor 3, a water inlet pipe 4 and a water outlet pipe 5. The outer wall of the motor 3 is provided with a uniformly distributed strip heat exchange port 6. A disc 1 7 is fixedly installed on the side of the motor 3 close to the pump body 2, and a disc 2 8 is fixedly installed on the side of the motor 3 away from the pump body 2. The discs 1 7 and 2 8 are both hollow, and a uniformly distributed heat exchange tube 9 is fixedly installed between the discs 1 7 and 2 8. The two ends of the heat exchange tube 9 are respectively connected to the disc 1 7 and the disc 2 8. The number of groups 9 is the same as the number of groups of the strip heat exchange port 6, and the heat exchange tubes 9 are respectively arranged in the strip heat exchange port 6, a water distribution pipe 10 is provided above the motor 3, and the two ends of the water distribution pipe 10 are respectively connected to the water outlet pipe 5 and the disc 2 8, and a small water pump 11 is provided at one end of the water distribution pipe 10 near the water outlet pipe 5, and a return pipe 12 is provided below the pump body 2, and the two ends of the return pipe 12 are respectively connected to the disc 1 7 and the pump body 2, a one-way valve 13 is provided on the return pipe 12, and a cooling pipe 14 is provided on the water distribution pipe 10.

[0025] When in use, the base 1 is used to support the installation of device components. When the circulating centrifugal pump is in use, the motor 3 is started, and the output shaft of the motor 3 rotates to drive the impeller in the pump body 2 to rotate. The rotating impeller generates centrifugal force, sucking water from the water inlet pipe 4 and accelerating it to be discharged from the water outlet pipe 5;

[0026] During the operation of the circulating centrifugal pump, the small water pump 11 and the cooling pipe 14 on the water distribution pipe 10 are started. The small water pump 11 draws the water in the outlet pipe 5 to the second disc 8. After the cooling pipe 14 cools the water, the water enters the second disc 8 and then flows through the heat exchange pipe 9 to absorb the heat emitted by the motor 3. Finally, the water flows back to the pump body 2 through the return pipe 12. The one-way valve 13 is set on the return pipe 12 to ensure that the water can only flow from the first disc 7 to the pump body 2 to prevent the water from flowing back.

[0027] The circulating centrifugal pump can continuously, efficiently and stably dissipate heat from the motor 3, ensuring that the motor 3 maintains a good operating temperature even under long-term, high-load operation, thereby improving the stability and service life of the circulating centrifugal pump.

[0028] A valve 15 is provided in each water distribution pipe 10, and the valve 15 opens toward the side of the disc 7;

[0029] The valve 15 can control the flow direction of the fluid, ensuring that the coolant can smoothly return to the disc 7 after flowing through the heat exchange tube 9, and flow back to the pump body 2 through the return pipe 12, completing the entire circulation process. At the same time, the valve 15 can also prevent the fluid from flowing back to a certain extent, ensuring the stability and efficiency of the heat dissipation system.

[0030] A filter screen 16 is provided at the end of the water distribution pipe 10, and the filter screen 16 is provided between the water outlet pipe 5 and the small water pump 11;

[0031] During the operation of the circulating centrifugal pump, the water flow in the outlet pipe 5 is first filtered by the filter 16 before entering the water distribution pipe 10. The filter 16 can block impurities in the water and prevent impurities from entering the small water pump 11 and the water distribution pipe 10, avoiding blockage or damage to these components, thereby ensuring the normal operation of the heat dissipation system.

[0032] The size of the strip heat exchange port 6 is adapted to the size of the heat exchange tube 9, and the heat exchange tube 9 is set to be a heat-absorbing metal material;

[0033] Since the strip heat exchange port 6 is adapted to the size of the heat exchange tube 9, the heat exchange tube 9 can be tightly installed in the strip heat exchange port 6, maximizing the contact area between the heat exchange tube 9 and the motor 3 casing, thereby improving the heat transfer efficiency. At the same time, the heat exchange tube 9 made of heat-absorbing metal material has good thermal conductivity, can quickly absorb the heat emitted by the motor 3, and transfer the heat to the water flowing through the inside of the heat exchange tube 9.

[0034] The sides of the disc 1 7 and the disc 2 8 are respectively fitted with the two ends of the motor 3, and the disc 1 7 and the disc 2 8 are both made of heat-absorbing metal material;

[0035] When the motor 3 is running, heat will also be generated at both ends of the motor 3. Since the disk 1 7 and the disk 2 8 are made of heat-absorbing metal and fit tightly with the two ends of the motor 3, they can quickly absorb the heat at both ends of the motor 3, further improving the heat dissipation effect of the motor 3.

[0036] A controller is provided on the base 1, and the controller is electrically connected to the motor 3, the small water pump 11, and the cooling pipe 14 respectively;

[0037] Setting up a controller can automatically control each component of the device.

[0038] Working principle:

[0039] When in use, the base 1 is used to support the installation of device components. When the circulating centrifugal pump is in use, the motor 3 is started, and the output shaft of the motor 3 rotates to drive the impeller in the pump body 2 to rotate. The rotating impeller generates centrifugal force, sucking water from the water inlet pipe 4 and accelerating it to be discharged from the water outlet pipe 5;

[0040] During the operation of the circulating centrifugal pump, the small water pump 11 and the cooling pipe 14 on the water distribution pipe 10 are started. The small water pump 11 draws the water in the outlet pipe 5 to the second disc 8. After the cooling pipe 14 cools the water, the water enters the second disc 8 and then flows through the heat exchange pipe 9 to absorb the heat emitted by the motor 3. Finally, the water flows back to the pump body 2 through the return pipe 12. The one-way valve 13 is set on the return pipe 12 to ensure that the water can only flow from the first disc 7 to the pump body 2 to prevent the water from flowing back.

[0041] The valve 15 in the water distribution pipe 10 can control the flow direction of the fluid, ensuring that the coolant can smoothly return to the disc 1 7 after flowing through the heat exchange tube 9, and then flow back to the pump body 2 through the return pipe 12, completing the entire circulation process. At the same time, the valve 15 can also prevent the fluid from flowing back to a certain extent, ensuring the stability and efficiency of the cooling system.

[0042] During the operation of the circulating centrifugal pump, the water in the outlet pipe 5 is first filtered by the filter 16 before entering the water distribution pipe 10. The filter 16 can block impurities in the water and prevent them from entering the small water pump 11 and the water distribution pipe 10, avoiding blockage or damage to these components, thereby ensuring the normal operation of the heat dissipation system.

[0043] Since the strip-shaped heat exchange port 6 is compatible with the size of the heat exchange tube 9, the heat exchange tube 9 can be tightly installed in the strip-shaped heat exchange port 6, maximizing the contact area between the heat exchange tube 9 and the motor 3 housing, thereby improving the heat transfer efficiency. At the same time, the heat exchange tube 9 made of heat-absorbing metal material has good thermal conductivity, which can quickly absorb the heat emitted by the motor 3 and transfer the heat to the water flowing through the heat exchange tube 9.

[0044] When the motor 3 is running, heat will also be generated at both ends of the motor 3. Since the disk 1 7 and the disk 2 8 are made of heat-absorbing metal and fit tightly with the two ends of the motor 3, they can quickly absorb the heat at both ends of the motor 3, further improving the heat dissipation effect of the motor 3.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
