Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of X-ray source heat dissipation, in particular to an X-ray source heat dissipation system. BACKGROUND

[0002] When the X-ray source works, 99% of the power is converted into heat energy, and only 1% of the energy is converted into effective rays. The heat generated by the heat source (ray tube and internal device) during work is absorbed by the transformer oil, and then the heat of the transformer oil is transmitted to the shell, and the heat is dissipated to the outside through the shell. This is passive heat dissipation. For small power or intermittent working ray sources, this method can be used; however, for high-power or long-time uninterrupted working X-ray sources, if passive heat dissipation is still used, only by increasing the volume of the oil tank can the heat dissipation effect be achieved. This method will increase the volume and weight of the ray source, and also increase the economic cost; if the heat cannot be dissipated in time, the service life of the equipment will be shortened, and therefore needs to be improved.
