Description

TECHNICAL FIELD

[0001] The utility model relates to X ray source field, concretely is a kind of X ray source circulating cooling heat sink. BACKGROUND

[0002] X ray source, also called X ray generator, X ray source has wide application in multiple fields. It is mainly used to generate X ray, and these rays can penetrate matter, so that people can observe the internal structure of matter. In the X ray tube, the electrons emitted from the cathode are accelerated by the electric field between the cathode and the anode, and then bombard the X ray anode target, transferring their kinetic energy to the atoms on the target. About 1% of the energy is converted into X rays, which are emitted from the X ray irradiation window. In the medical field, X ray source is used for X ray imaging to help doctors diagnose fractures, lung problems, etc.

[0003] In the prior art, when the high-speed moving electrons bombard the X ray anode target, most of the electron energy is converted into heat, causing the X ray source to heat up, so that the temperature of the X ray source is relatively high during use. High temperature may cause the performance of the electronic components inside the X ray source to decline, thereby affecting the stability and accuracy of the equipment. Generally, to achieve cooling and heat dissipation of the X ray source, a cooling water pipe is arranged on the surface of the X ray source, or the X ray source is immersed in water. Water circulation and refrigeration pipe are used to cool the water source, achieving heat dissipation of the X ray source. However, due to the limitations of heat conduction and fluid dynamics, water molecules close to the refrigeration pipe can quickly absorb the refrigeration effect and reduce the temperature, while water areas far from the refrigeration pipe have low heat diffusion efficiency, and their temperature is difficult to significantly reduce in a short time, forming a local temperature gradient phenomenon. The water source that has not been completely cooled is pumped into the heat dissipation pipe, which may cause inconsistent temperature of the water source for heat dissipation of the X ray source, or the temperature of the water source is too high to effectively cool the X ray source, thereby reducing the effect of heat dissipation of the X ray source.
