The X-ray tube assembly is mounted on an X-ray diagnosis apparatus such as CT, DR, C-arm and the like, and is mainly used for generating X-rays. In the working process, the X-ray tube lamp filament is heated, electron cloud is formed on the surface of the filament, and then electrons are bombarded to the tungsten-rhenium alloy on the anode target surface through high-voltage acceleration, so that bremsstrahlung is formed, and finally X-rays are generated. Wherein 99% of the energy impinging on the anode is converted into heat and only 1% of the energy forms X-rays.
The X-ray tube assembly is typically composed of components such as an X-ray tube, a tube sleeve, a heat sink, high voltage insulation oil, and the like. The radiator discharges high-voltage insulating oil in the tube sleeve of the ray tube through the oil pump, and radiates heat through the condenser and the fan in the radiator, so that the temperature of the high-voltage insulating oil is reduced, and the cooled high-voltage insulating oil is injected into the oil inlet. When the X-ray tube assembly works, a large amount of heat is generated, and the heat dissipation capacity and stability of the radiator determine that the X-ray tube assembly can work normally and stably.
If the radiator is abnormal, the X-ray tube is abnormal at high temperature, and the pressure resistance of the high-voltage insulating oil at high temperature is greatly reduced. The above phenomenon can affect the normal operation of the X-ray tube, thereby causing the X-ray tube to be broken, so that the radiator needs to be monitored in real time, and unnecessary losses are avoided.

Referring to fig. 1, 2, 3 and 4, an air volume detecting device for an X-ray tube assembly includes: an X-ray tube assembly 10 and a heat sink 20, wherein the X-ray tube assembly 10 is connected to the heat sink 20 and wherein the heat sink 20 comprises a fan 210, the apparatus further comprising: an air volume sensor 30 and a controller 40, wherein the air volume sensor 30 is connected with the fan 210 and configured to measure the air volume generated by the fan 210; and the controller 40 is connected to the air volume sensor 30 and configured to receive the air volume data measured by the air volume sensor 30.
As described in the background, an X-ray tube assembly is typically composed of components such as an X-ray tube, a tube sleeve, a heat sink, high voltage insulation oil, and the like. The radiator discharges high-voltage insulating oil in the tube sleeve of the ray tube through the oil pump, and radiates heat through the condenser and the fan in the radiator, so that the temperature of the high-voltage insulating oil is reduced, and the cooled high-voltage insulating oil is injected into the oil inlet. When the X-ray tube assembly works, a large amount of heat is generated, and the heat dissipation capacity and stability of the radiator determine that the X-ray tube assembly can work normally and stably.
If the radiator is abnormal, the X-ray tube is abnormal at high temperature, and the pressure resistance of the high-voltage insulating oil at high temperature is greatly reduced. The above phenomenon can affect the normal operation of the X-ray tube, thereby causing the X-ray tube to be broken, so that the radiator needs to be monitored in real time, and unnecessary losses are avoided.
In view of this, the present application provides an air volume detection device for an X-ray tube assembly. The system comprises: an X-ray tube assembly 10 and a heat sink 20. Wherein the X-ray tube assembly 10 is connected to a heat sink 20. And, moreover, the method comprises the steps of. The heat sink 20 also includes a fan 210. Furthermore, the device comprises: an air volume sensor 30 and a controller 40. 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, referring to fig. 2, 3 or 4, the air volume sensor 30 is disposed between the fan 210 and the X-ray tube assembly 10, so that the actual air volume transmitted to the X-ray tube assembly 10 by the fan 210 can be measured.
First, when the fan 210 is operating, the air volume sensor 30 connected to the fan 210 can measure the test air volume Q when the fan 210 is operating normally t 。
Further, the air volume sensor 30 transmits the measured test air volume Qt of the fan 210 in normal operation to the controller 40. The controller 40 collects the air volume from the air volume sensor 30And recording and judging the data. During normal operation of the fan 210, the actual air volume Qr delivered to the X-ray tube assembly 10<b×Q t The fan 210 is judged to be abnormal. The controller 40 will thus cease high voltage operation of the X-ray tube assembly 10 and cease loading of filament current within the X-ray tube assembly 10. Further, the controller 40 transmits abnormality information of the fan 210 to the console 60.
Further, since the fan 210 tends to suffer from dust accumulation, dirt accumulation, or aging after a long period of use, the parameter b represents a parameter when the fan 210 is affected by the environment or aged by itself. And 0 is 0<b<0.5. In addition, if the fan 210 cannot rotate due to aging, b=0. That is, the actual air volume Q transmitted to the X-ray tube assembly 10 at this time r ＝0。
In the prior art, the X-ray tube assembly 10 can be operated normally even though the fan 210 is not rotated, and the X-ray tube assembly 10 feeds back the abnormality information to the controller 40 only when the temperature of the high-voltage insulating oil in the X-ray tube assembly 10 reaches the safety threshold. However, the temperature of the high-voltage insulating oil in the X-ray tube assembly 10 cannot be lowered due to failure to timely restart the operation of the fan 210, and thus damage may have been caused to the X-ray tube assembly 10 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 timely find that the fan 210 cannot rotate, thereby ensuring the service life of the X-ray tube assembly 10.
In summary, since the air volume sensor 30 is disposed in front of the fan 210, the air volume sensor 30 can timely feed back the current air volume after the air flow passes through the heat dissipation fins of the condenser 220. Also, 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 operation of the X-ray tube assembly 10. Therefore, by installing the air volume sensor 30 between the fan 210 and the X-ray tube assembly 10, measuring the air volume of the current air flow passing through the heat dissipation fins of the condenser 220 by using the air volume sensor 30, and sending the air volume data to the controller 40, the technical effect of monitoring the working state of the radiator 20 in real time and further ensuring the normal working of the X-ray tube assembly 10 is achieved. Further, the technical problem that if the radiator 20 is abnormal in the prior art, the X-ray tube assembly 10 is abnormal at high temperature, so that the radiator 20 needs to be monitored in real time is solved.
Optionally, the heat sink 20 includes: a condenser 220, wherein the condenser 220 is coupled to the X-ray tube assembly 10 and configured to cool the X-ray tube assembly 10; and fan 210 is also coupled to condenser 220 and configured to provide an airflow to condenser 220.
Specifically, referring to fig. 1, the radiator 20 further includes a condenser 220. Wherein the condenser 220 is connected to the X-ray tube assembly 10.
First, the radiator 20 pumps out the high-voltage insulating oil in the X-ray tube assembly 10 and passes it through the condenser 220 in the radiator 20. The condenser 220 and the fan 210 cool down the high-voltage insulating oil, and allow the cooled down high-voltage insulating oil to enter the X-ray tube assembly 10 again. Thereby ensuring proper operation of the X-ray tube assembly 10.
Further, a fan 210 is connected to the condenser 220. And since the condenser 220 is a refrigerating device, the condenser 220 starts to operate 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. Since the whole operation of the condenser 220 is exothermic, the temperature of the whole operation of the condenser 220 is high, and the fan 210 is required to cool the condenser 220, thereby ensuring the life of the condenser 220.
In addition, when the fan 210 generates an air flow, the actual air volume reaching the X-ray tube assembly 10 is attenuated due to the structure of the condenser 220. The air volume sensor 30 measures the test air volume Q when the fan 210 is working normally t In the case of (a), the air supply efficiency v of the fan 210 may be expressed by the following formula:
wherein Q is s Indicating the rated air volume that the fan 210 can provide.
Thus, the test air quantity Q of the fan 210 during normal operation is obtained through measurement t And collect the rated air quantity Q provided by the fan 210 s The technical effect of improving the air supply efficiency v of the fan 210 is achieved.
Optionally, the method further comprises: an oil pump 50, wherein one end of the oil pump 50 is connected to the air volume sensor 30, the condenser 220, and the fan 210, respectively; and the other end of the oil pump 50 is connected to the X-ray tube assembly 10. Further optionally, the method further comprises: an oil inlet 110 and an oil outlet 120 provided on the X-ray tube assembly 10, wherein the oil inlet 110 is connected with the oil pump 50; and oil outlet 120 is connected to air volume sensor 30, condenser 220, and fan 210, respectively.
Specifically, referring to fig. 1, the system is further provided with an oil pump 50. One end of the oil pump 50 is connected to the air volume sensor 30, the condenser 220, and the fan 210, respectively, and the other end is connected to the X-ray tube assembly 10.
Further, an oil inlet 110 and an oil outlet 120 are also provided on the X-ray tube assembly 10. The oil inlet 110 is connected with the oil pump 50, and the oil outlet 120 is connected with the air volume sensor 30, the condenser 220 and the fan 210, respectively.
First, the oil pump 50 pumps out the high-voltage insulating oil in the X-ray tube assembly 10 (i.e., the high-voltage insulating oil having a relatively high temperature) through the oil outlet 120, and causes the high-voltage insulating oil to enter the condenser 220, and the condenser 220 cools the high-voltage insulating oil. Then, the oil pump 50 pumps the cooled high-voltage insulation oil into the X-ray tube assembly 10 through the oil inlet 130, so that the X-ray tube assembly 10 continues to operate normally.
Optionally, the method further comprises: an operator station 60, wherein the operator station 60 is coupled to 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, an error message of the abnormality of the fan 210 is sent to the console 60. After receiving the error message of the fan 210, the console 60 confirms whether the error message is caused by the abnormality of the fan 210. In the event that the error message is determined to be due to an abnormality in the fan 210, the fan 210 is contacted for replacement by the provider, or the fan 210 is contacted for cleaning by the provider. The fan 210 error message cannot be used until the next air volume sensor 30 detects.
Therefore, by setting the operation console 60 connected with the controller 40, the technical effect that the fan 210 can be normally used is achieved by timely communicating with the supplier when the fan 210 is determined to be abnormal.
Optionally, the X-ray tube assembly 10 includes: an X-ray tube housing 130 and an X-ray tube 140 disposed in the X-ray tube housing 130, wherein the oil inlet 110 and the oil outlet 120 are disposed on the X-ray tube housing 130.
Specifically, referring to fig. 1, the X-ray tube assembly 10 further includes: the X-ray tube housing 130 and the X-ray tube 140 disposed in the X-ray tube housing 130. Wherein the X-ray tube 140 is mainly used for generating X-rays.
Since the air volume sensor 30 is disposed in front of the fan 210, the air volume sensor 30 can timely feed back the current air volume after the air flow passes through the heat dissipation fins of the condenser 220. Also, 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 operation of the X-ray tube assembly 10. Therefore, by installing the air volume sensor 30 in front of the fan 210, measuring the air volume of the current air flowing through the heat dissipation fins of the condenser 220 by using the air volume sensor 30, and sending the air volume data to the controller 40, the technical effect of monitoring the working state of the radiator 20 in real time and further ensuring the normal working of the X-ray tube assembly 10 is achieved. Further, the technical problem that if the radiator 20 is abnormal in the prior art, the X-ray tube assembly 10 is abnormal at high temperature is solved, so that the radiator 20 needs to be monitored in real time, and the normal operation of the X-ray tube assembly is ensured.
The application has the following advantages:
1. the operation state of the fan 210 in the radiator 20 can be detected in real time;
2. when the fan 210 is in an abnormal state, the air volume sensor 30 timely transmits abnormal information to the controller 40, thereby stopping the high-voltage operation of the X-ray tube assembly 10 and stopping the loading of filament current in the X-ray tube 140, and further avoiding damage to the X-ray tube 140;
3. the controller 40 sends the abnormal information of the fan 210 to the operation table 60, the operation table 60 ejects the abnormal information of the fan 210, and communicates with a supplier by using the operation table 60, so that the condenser 220 is cleaned or the fan 210 is replaced, and the service life of the X-ray tube assembly 10 is prolonged; and
4. the fan 210 abnormality information is ejected at the console 60, and interference of other abnormality information of the X-ray tube assembly 10 with a field engineer is avoided.
