Background technique

The X-ray tube assembly is installed on X-ray diagnostic equipment such as CT, DR, and C-arm, and is mainly used to generate X-rays. During the working process, the X-ray tube filament is heated to form an electron cloud on the surface of the filament, and then the electrons are bombarded to the tungsten-rhenium alloy on the anode target surface by high-voltage acceleration, thereby forming bremsstrahlung and finally generating X-rays. Among them, 99% of the energy bombarded to the anode is converted into heat, and only 1% of the energy forms X-rays.

X-ray tube assembly is usually composed of X-ray tube, tube sleeve, radiator, high-voltage insulating oil and other components. Among them, the radiator discharges the high-voltage insulating oil inside the ray tube sleeve through the oil pump, and dissipates heat through the condenser and fan in the radiator, thereby reducing the temperature of the high-voltage insulating oil, and then injects the cooled high-voltage insulating oil into the oil inlet . When the X-ray tube assembly is working, it will generate a lot of heat. The heat dissipation capacity and stability of the radiator determine that the X-ray tube assembly can work normally and stably.

And if there is an abnormality in the radiator, the X-ray tube will have an abnormal high temperature phenomenon, and the pressure resistance of the high-voltage insulating oil under high temperature conditions will also be greatly reduced. The above phenomena will affect the normal operation of the X-ray tube, thereby causing the X-ray tube to break, so it is necessary to monitor the radiator in real time to avoid unnecessary losses.

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of air volume detection device for X-ray tube assembly includes: X-ray tube assembly 10 and radiator 20, wherein X-ray tube assembly 10 and radiator 20 Connect, and give wherein radiator 20 comprises fan 210, device also comprises: air volume sensor 30 and controller 40, and wherein air volume sensor 30 is connected with fan 210, is configured to measure the air volume that fan 210 produces; And controller 40 and air volume sensor 30, configured to receive the air volume data measured by the air volume sensor 30.

As mentioned in the background art, an X-ray tube assembly usually consists of an X-ray tube, a tube sleeve, a radiator, high-voltage insulating oil and other components. Among them, the radiator discharges the high-voltage insulating oil inside the ray tube sleeve through the oil pump, and dissipates heat through the condenser and fan in the radiator, thereby reducing the temperature of the high-voltage insulating oil, and then injects the cooled high-voltage insulating oil into the oil inlet . When the X-ray tube assembly is working, it will generate a lot of heat. The heat dissipation capacity and stability of the radiator determine that the X-ray tube assembly can work normally and stably.

And if there is an abnormality in the radiator, the X-ray tube will have an abnormal high temperature phenomenon, and the pressure resistance of the high-voltage insulating oil under high temperature conditions will also be greatly reduced. The above phenomena will affect the normal operation of the X-ray tube, thereby causing the X-ray tube to break, so it is necessary to monitor the radiator in real time to avoid unnecessary losses.

In view of this, the present application provides an air volume detection device for an X-ray tube assembly. The system includes: an X-ray tube assembly 10 and a radiator 20 . Wherein, the X-ray tube assembly 10 is connected with the radiator 20 . and. The radiator 20 also includes a fan 210 . In addition, the device also includes: an air volume sensor 30 and a controller 40 . Wherein, the air volume sensor 30 is connected to the radiator 20 and is configured to measure the air volume generated by the radiator 20 . The controller 40 is connected to the air volume sensor 30 and is configured to receive air volume data measured by the air volume sensor 30 . Specifically, as shown in FIG. 2 , FIG. 3 or FIG. 4 , the air volume sensor 30 is disposed between the fan 210 and the X-ray tube assembly 10 , so as to measure the actual air volume transmitted by the fan 210 to the X-ray tube assembly 10 .

Firstly, when the fan 210 is working, the air volume sensor 30 connected to the fan 210 can measure the test air volume Q _t when the fan 210 is working normally.

Further, the air volume sensor 30 sends the measured air volume Qt measured when the fan 210 works normally to the controller 40 . The controller 40 records and judges the air volume data collected by the air volume sensor 30 . During normal operation of the fan 210 , if the actual air volume Qr<b×Q _t transmitted to the X-ray tube assembly 10 , it is determined that the fan 210 is abnormal. Therefore, the controller 40 will stop the high-voltage operation of the X-ray tube assembly 10 and stop the loading of the filament current in the X-ray tube assembly 10 . In addition, the controller 40 sends the abnormality information of the fan 210 to the console 60 .

Moreover, since the fan 210 is often used for a long time, there will be dust accumulation, dirt accumulation or aging problems, so the parameter b represents the parameter when the fan 210 is affected by the environment or itself is aging. And, 0<b<0.5. In addition, if the fan 210 cannot rotate due to aging, then b=0. That is, the actual air volume Q _r transmitted to the X-ray tube assembly 10 at this time = 0.

In the prior art, even if the fan 210 cannot rotate, the X-ray tube assembly 10 can still work normally, and only when the temperature of the high-voltage insulating oil in the X-ray tube assembly 10 reaches a safe threshold, the X-ray tube assembly 10 will The abnormality information is fed back to the controller 40 . However, the temperature of the high-voltage insulating oil in the X-ray tube assembly 10 cannot be lowered because the fan 210 cannot be restarted in time, so the X-ray tube assembly 10 may have been damaged at this time.

Further, since the technical solution of the present application can detect the air volume data of the fan 210 in real time, the air volume sensor 30 can detect that the fan 210 cannot rotate in time, thereby ensuring the service life of the X-ray tube assembly 10 .

To sum up, since the air volume sensor 30 is provided in front of the fan 210 , the air volume sensor 30 can timely feed back the air volume of the current airflow passing through the cooling fins of the condenser 220 . Since the air volume sensor 30 is connected to the controller 40, when the air volume generated by the fan 210 is abnormal, the air volume sensor 30 can transmit the air volume data to the controller 40, so that the controller 40 stops the X-ray tube assembly 10 from working. Therefore, by installing the air volume sensor 30 between the fan 210 and the X-ray tube assembly 10, and using the air volume sensor 30 to measure the air volume of the current air flow passing through the cooling fins of the condenser 220, and then sending the air volume data to the controller 40, This achieves the technical effect of being able to monitor the working state of the radiator 20 in real time, thereby ensuring the normal operation of the X-ray tube assembly 10 . Furthermore, it solves the technical problem in the prior art that if the radiator 20 is abnormal, the X-ray tube assembly 10 will have high temperature abnormality, so the radiator 20 needs to be monitored in real time.

Optionally, the radiator 20 includes: a condenser 220, wherein the condenser 220 is connected to the X-ray tube assembly 10 and is configured to cool down the X-ray tube assembly 10; and the fan 210 is also connected to the condenser 220 and is configured to Condenser 220 provides the gas flow.

The condenser 220 and the fan 210 cool down the high-voltage insulating oil, and make the cooled high-voltage insulating oil enter the X-ray tube assembly 10 again. Therefore, the normal operation of the X-ray tube assembly 10 is ensured.

Further, the fan 210 is connected with the condenser 220 . And because the condenser 220 is a cooling device, when the radiator 20 pumps out the high-voltage insulating oil in the X-ray tube assembly 10 and makes it enter the condenser 220, the condenser 220 starts to work. Since the entire working process of the condenser 220 is a process of releasing heat, the temperature of the entire working process of the condenser 220 is relatively high, and the fan 210 also needs to cool the condenser 220 to ensure the life of the condenser 220 .

In addition, after the fan 210 generates airflow, due to the structure of the condenser 220 , the actual air volume reaching the X-ray tube assembly 10 will be attenuated. In the case that the air volume sensor 30 has measured the test air volume _Qt of the fan 210 in normal operation, the air supply efficiency v of the fan 210 can be expressed by the following formula:

Wherein, Q _s represents the rated air volume that the fan 210 can provide.

Therefore, by measuring the test air volume Q _t when the fan 210 works normally, and collecting the rated air volume Q _s that the fan 210 can provide, the technical effect of improving the air supply efficiency v of the fan 210 is achieved.

First, the oil pump 50 pumps out the high-voltage insulating oil in the X-ray tube assembly 10 through the oil outlet 120 (that is, high-voltage insulating oil with a higher temperature), and makes the high-voltage insulating oil enter the condenser 220, and the condenser 220 High voltage insulating oil for cooling. Then, the oil pump 50 pumps the cooled high-voltage insulating oil into the X-ray tube assembly 10 through the oil inlet 130 , so that the X-ray tube assembly 10 continues to work normally.

Optionally, it also includes: an operation console 60, wherein the operation console 60 is connected with the controller 40 and configured for communication.

Specifically, referring to FIG. 1 , when the controller 40 records the air volume data measured by the air volume sensor 30 and determines that the fan 210 is abnormal, it sends an error message indicating that the fan 210 is abnormal to the console 60 . After receiving the error information of the fan 210 , the console 60 confirms whether the error information is caused by the abnormality of the fan 210 . If it is determined that the error message is caused by the abnormality of the fan 210, contact the supplier to replace the fan 210, or contact the supplier to clean the fan 210. It cannot be used until the air volume sensor 30 detects no error information of the fan 210 next time.

Therefore, by setting the console 60 connected with the controller 40, the technical effect of communicating with the supplier in time to ensure the normal use of the fan 210 is achieved when it is determined that the fan 210 is abnormal.

Optionally, the X-ray tube assembly 10 includes: an X-ray tube sleeve 130 and an X-ray tube 140 disposed in the X-ray tube sleeve 130, wherein the oil inlet 110 and the oil outlet 120 are both arranged in the X-ray tube sleeve 130 on.

Specifically, referring to FIG. 1 , the X-ray tube assembly 10 further includes: an X-ray tube sleeve 130 and an X-ray tube 140 disposed in the X-ray tube sleeve 130 . Among them, the X-ray tube 140 is mainly used for generating X-rays.

Since the air volume sensor 30 is arranged in front of the fan 210 , the air volume sensor 30 can timely feed back the air volume of the current airflow passing through the cooling fins of the condenser 220 . Since the air volume sensor 30 is connected to the controller 40, when the air volume generated by the fan 210 is abnormal, the air volume sensor 30 can transmit the air volume data to the controller 40, so that the controller 40 stops the X-ray tube assembly 10 from working. Thereby, by installing the air volume sensor 30 in front of the fan 210, and using the air volume sensor 30 to measure the air volume of the current air flow passing through the cooling fins of the condenser 220, and then sending the air volume data to the controller 40, the real-time monitoring of heat dissipation can be achieved.
