Description

Pipe target cooling device

Technical Field

The utility model relates to a bulb field specifically is a pipe target cooling device.

Background

The CT tube, which is the core component of CT, is actually a large high vacuum cathode ray diode, which is the system for generating x-rays.

The working process is as follows: the cathode filament is heated by 12V current and generates a free electron cloud set, when 40-150 kV high-voltage electricity is applied to the cathode and the anode, the potential difference is increased sharply, free electron beams in an active state are driven by a high-voltage strong electric field and impact the anode molybdenum-based tungsten target at high speed by the cathode, energy conversion is generated, about l% of electric energy forms an x-ray and is emitted by a window, and 99% of electric energy is converted into heat energy and is emitted by a heat dissipation system. The x-ray is a short electromagnetic wave with strong penetration, and the higher the voltage, the stronger the penetration. The X-ray is partially absorbed or attenuated during the process of penetrating the substance, which is the physical basis of X-ray imaging. The principle is utilized to lead the tissues of the human body to generate ray projections with different attenuations, and lead the silver bromide of the film to be black after being developed; the non-photosensitive silver bromide is developed to be transparent white by fixing, thereby generating black and white images, which is the photographic effect. In addition, the penetration degree or the absorption attenuation degree of the x-ray is also related to the density and the thickness of the irradiated object, the level difference of black and white shadows displayed on the image represents the density difference of human tissues, the higher the density is, the more the absorption is, the less the penetration is, the less the light is, and the whiter the image is; otherwise, the darker the color. The density of human tissue changes when pathological changes occur, and the black and white image of the image changes, which is the image diagnosis principle.

The current latest technology of a target disc cooling structure in anode water cooling is a combined structure of embedded solid fins and bottom water cooling, and heat generated by a target disc is conducted to the fins and then conducted to bottom circulating water for circulating cooling.
