Abstract
Description
Technical Field
[0001] This utility model relates to the field of X-ray tube cooling, specifically to an X-ray tube anode cooling device. Background Technology
[0002] When an X-ray tube is working, the electron beam bombards the anode target surface, and about 99% of the energy is converted into heat energy (only 1% is converted into X-rays), causing the anode temperature to rise sharply (up to hundreds to thousands of degrees Celsius). Although the anode target material (such as tungsten) has a high melting point (3422℃), continuous high temperature will cause tungsten to evaporate, the target surface to crack, and even destroy the vacuum level of the vacuum tube shell. Therefore, it is necessary to control the temperature through efficient heat dissipation.
[0003] Currently, when cooling the anode of an X-ray tube, metal heat sinks (mostly made of aluminum or copper) are typically installed on the outside of the anode target or anode cover to increase the heat exchange efficiency by increasing the heat dissipation area. The heat sinks are comb-shaped or radially arranged to expand the contact area with the air. A fan (axial or centrifugal) drives the airflow, accelerating air convection on the surface of the heat sink. The fan is usually installed near the heat sink to create a directional airflow (e.g., air is drawn in from one end of the heat sink and exhausted from the other).
[0004] However, air cooling is difficult to quickly suppress the surge in anode temperature, especially under continuous operation or high load conditions. The anode target may experience tungsten evaporation and cracking of the target surface due to continuous high temperature, which will shorten the life of the X-ray tube. Utility Model Content
[0005] Based on this, the purpose of this utility model is to provide an X-ray tube anode cooling device, which aims to solve the problem that current air cooling is difficult to quickly suppress the anode temperature surge, especially under continuous operation or high load conditions, the anode target may experience tungsten evaporation and target surface cracking due to continuous high temperature, thus shortening the life of the X-ray tube.
