The inventor of the invention has carried out a great deal of creative work, overcomes the inertia thinking, and proposes a concept of an oil collecting ring assembly, which is respectively connected with a rotating part and a stationary part of a CT machine, and forms two annular oil collecting channels between the rotating part and the stationary part of the CT machine, so that during the rotation of an X-ray tube, hot cooling oil can be injected into one annular oil collecting channel for collecting the hot cooling oil of the oil collecting ring assembly through an oil collecting hole on the rotating part, and the cooling oil in the annular oil collecting channel containing the cold cooling oil of the oil collecting ring assembly can be received through another oil collecting hole on the rotating part, and the oil collecting ring assembly is connected with an external heat exchanger which is positioned at the stationary part of the stand or outside the stand through the oil collecting hole on the stationary part, so as to circularly cool the cooling oil in the annular oil collecting channel, therefore, the heat of the X-ray bulb tube can be directly transferred to a heat exchanger positioned at the static part of the rack or outside the rack through liquid such as cooling oil, oil cooling of the X-ray bulb tube is realized, and a bulb tube cooler is omitted.
The rotating part of the CT machine may be a turntable, and the stationary part may be a stationary ring of a rotary bearing or a stationary housing.
