All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The heat sink for an X-ray tube according to an embodiment of the present invention will be described with reference to fig. 1 to 4.

In some embodiments, the X-ray machine tube heat sink includes a water tank 1, a motor pump 2, a water flow meter 3, a check valve 4 and a water flow electronic control unit 5, a water inlet of the water tank 1 is used for communicating with a water outlet of the X-ray machine tube 6, a water outlet of the water tank 1 is communicated with a water inlet of the motor pump 2 through a water pipe, a water outlet of the motor pump 2 is communicated with a water inlet of the water flow meter 3 through a water pipe, a water outlet of the water flow meter 3 is in threaded connection with a water inlet of the check valve 4, an outlet of the check valve 4 is in threaded connection with a water inlet of the water flow electronic control unit 5, a water outlet of the:

the water flow electric control unit 5 is a tubular structure 51 which is communicated up and down, as shown in fig. 2, a first fixing piece 52 is arranged on the upper part of the inner wall of the tubular structure 51, a through hole which is through up and down is arranged on the first fixing piece 52, and a magnet is arranged at the center position of the lower end face of the first fixing piece 52;

a second fixing member 54 is arranged at the lower part of the inner wall of the tubular structure 51, as shown in fig. 2, the second fixing member 54 is an annular sealing structure with a circular through hole arranged at the central position, as shown in fig. 3, a cone floater 55 in a cone structure is arranged at the central position of the second fixing member 54, the vertex of the cone floater 55 is downwards embedded into the circular through hole of the second fixing member 54, a magnet with the same polarity as that of the magnet on the lower section of the first fixing member 52 is arranged on the upper end surface of the upper section of the cone floater 55, and the cone floater 55 and the second fixing member 54 form an upper and lower sealing structure under the action of magnetic force of the same polarity;

as shown in fig. 2, a magneto switch 57 is fixed on the outer side of the tube wall of the tube-shaped structure 51 and at the same horizontal position as the second fixing member 54, and the magneto switch 57 is used for connecting with a CPU of an X-ray machine.

In some embodiments, when the tank 1 is empty or the motor pump 2 is not operating, i.e. no cooling water is flowing through, the float in the water flow meter 3 is at measurement zero, no flow measurement. The cone floater 55 of the water flow electric control unit 5 and the second fixing piece 54 form an up-and-down sealing structure under the action of like-pole repulsive magnetic force;

when the water tank 1 has water and the motor pump 2 operates and meets the requirements simultaneously, under the power action of the motor pump 2, cooling water in the water tank 1 enters the water flow meter 3 through the motor pump 2, at the moment, a floater in the water flow meter 3 floats to measure a flow value, the cooling water enters the water flow electric control unit 5 through the one-way valve 4, the cone floater 55 floats upwards under the thrust action of the cooling water and overcomes the magnetic action of like polarity repulsion to be separated from the second fixing piece 54, the water flow flows out of a water outlet of the water flow electric control unit 5 through a through hole of the first fixing piece 52 to enter a water inlet of the ray tube 6, a water outlet of the ray tube 6 is communicated with the water inlet of the water tank 1 to form a cooling circulation system, and the aim of cooling.

When the X-ray machine works, if the water tank 1 leaks water, the motor pump 2 is damaged, the one-way valve 4 is closed and the like, the water flow is zero or the water flow is too small, the thrust of the water flow is insufficient to overcome the magnetic action of repellent like poles, the cone floater 55 and the second fixing piece 54 cannot be maintained in a separated state, the cone floater 55 falls back to form an upper and lower sealing structure with the second fixing piece 54, at this time, the magnetic switch 57 senses the position fall of the cone floater 55 to be triggered, and sends a signal to the CPU of the X-ray machine to close the operation of the X-ray machine, so that the X-ray tube 6 of the X-ray machine does not work when no cooling water exists, the phenomenon that the X-ray tube 6 is in a high-temperature state for a long time is effectively.

In some embodiments, as shown in fig. 2, the height h of the cone float 55 is greater than the upper cross-sectional diameter d of the cone float 55. In the improvement, the cone floater 55 can not turn over up and down under the thrust action of the cooling water, and can only keep the top point downward to float up and down, thereby improving the operation reliability of the invention.

In some embodiments, the cross section of the first fixing member 52 may be a three-fork, four-fork or five-fork shape, as shown in fig. 4 a, b and c, or other through structures with fixing function, which can be easily conceived by those skilled in the art, and also fall within the protection scope of the present invention.

In some embodiments, the motor of the motor pump 2 may be a three-phase asynchronous motor and the check valve 4 may be a ball check valve. The three-phase asynchronous motor and the ball-shaped check valve are industrial devices used in a factory, do not need to be purchased in a common factory, and can be directly obtained from a warehouse. The present improvement further reduces the operating costs of the company.

In some embodiments, the operator may read a water flow threshold that causes the cone float 55 to float upward against the magnetic force based on the measured value of the water flow meter 3 (e.g., when the value of the water flow meter 3 is greater than 60L/min, cooling water is flowing, and when less than 60L/min, no cooling water is flowing). The working convenience of workers is improved.

In some embodiments, a cooling pump for cooling the cooling water is disposed between the water outlet of the tube 6 and the water inlet of the water tank 1, the water inlet of the cooling pump is communicated with the water outlet of the tube 6, and the water outlet of the cooling pump is communicated with the water inlet of the water tank 1. This improvement can cool off the cooling water that flows through the ray tube 6, makes the cooling water be in the low temperature state always, ensures the cooling capacity of cooling water. Cooling pumps are common in industrial applications and are not described in detail here.

Compared with the prior art, the X-ray machine ray tube heat dissipation device has the following advantages:

when the X-ray machine works, if the water tank leaks, the motor pump is damaged, the one-way valve is closed and the like, the water flow is zero or the water flow is too small, the thrust of the water flow is insufficient to overcome the magnetic action of the repulsion of the same poles, the cone floater and the second fixing piece cannot be maintained to be in a separated state, the cone floater falls back to form an upper sealing structure and a lower sealing structure with the second fixing piece, at the moment, the position of the cone floater is triggered by the magnetic switch to fall back, the X-ray machine is switched off by sending a signal to a CPU of the X-ray machine, the X-ray tube of the X-ray machine does not work when no cooling water exists, the work convenience of workers is improved, the long-time high-temperature state of the X-ray tube is effectively avoided.
