Abstract
The utility model discloses a rotary anode X-ray tubes with a radiator, witch solves the heat rejection problem of the rotary anode X ray tube. The heat of target surface of the rotary anode and the shaft bearing is diffused by the heat rejection device. Consequently, the service life of the rotary anode X ray tube is improved.
Description
The utility model relates to a kind of medicine equipment.
The rotating anode X-ray tube of countries in the world production at present, its structure is: a side is equipped with a monophase machine in the vitreum, motor directly drives a connecting rod, plate target is fixed on the connecting rod, motor drives the plate target rotation when rotating, opposite side is a filament size focus, the electron stream that emits from filament, directly impinge upon on the target surface, produce X ray.But when the pipe running hours, the temperature of whole target body rises very highly, makes target surface produce pit or be full of cracks.Invented the ultrahigh speed rotating anode X-ray tube for addressing this problem, electron stream is impinged upon on the anode target surface of high speed rotating uniformly, do not solved though this solves some heat dissipation problem root problems.If increase the diameter of connecting rod, heat is passed to the wearing and tearing that bearing and motor must cause bearing by connecting rod, heat is difficult for distributing, and causes the be full of cracks of anode target surface and the wearing and tearing of bearing, is the main cause that rotating anode X-ray tube that present countries in the world produce is scrapped.
Its feature of the utility model just is to provide a kind of rotating anode X-ray tube that has heat abstractor.
The purpose of this utility model is achieved in that at the back side of rotarting anode target surface, tens fin (Fig. 2 7) is housed becomes tens radiating surfaces by an original radiating surface, and the heat absorption that makes the anode target surface is to fin.This has just solved, and the target surface that causes chaps and the wearing and tearing of bearing because of heat is difficult for distributing, and the rotating anode life-span is improved.
Be described in further detail below in conjunction with accompanying drawing: 1. figure is existing rotating anode X-ray tube cutaway view.Figure is 2. for having the rotating anode X-ray tube cutaway view of heat abstractor: 1, for rotor and bearing, 2, for connecting rod, 3, for anode target surface, 4, for vitreum, 5, for cell body, 6 that filament is housed, for filament line, 7, be fin.
Claims (1)
- A kind of otating anode x ray tube has plate target, vitreum, rotor and bearing, the cell body of filament is housed, and its feature is equipped with tens fin with regard to the back that is otating anode x ray tube anode target surface.
