Self-cooling CT machine

Abstract

The invention relates to the field of medical devices, in particular to a self-cooling CT machine. The self-cooling CT machine includes a stator. A rotor is mounted in the stator, A stator is coveredwith a front cover and a rear cover, the rotor is provided with a plurality of blades distributed along the circumferential direction of the rotor, The inner circumference of the stator is provided with a centrifugal air duct opposite to the blade, the outer wall of the stator is provided with an air outlet duct communicating with the centrifugal air duct, the cross-sectional area of the centrifugal air duct is gradually enlarged clockwise along the inner circumference of the stator, the cross-sectional area of the joint of the centrifugal air duct and the air outlet duct is the largest, and aplurality of air inlets are arranged on the rear cover; An advantage of the present invention is the high speed rotation of the rotor, so that the blades on the rotor drive the hot air to rotate, therotating hot air is discharged from the air outlet channel through the centrifugal air duct under the action of the centrifugal force, and the pressure at the air inlet is reduced due to the gas discharged from the stator inner cavity, and the external cold air is sucked into the stator cavity from the air inlet, thereby lowering the temperature of the stator and the rotor and realizing heat dissipation.

Problems solved by technology

[0002] During the scanning process of CT equipment, in addition to X-rays, a large amount of heat energy will be generated when the tube is exposed. The heat energy will be emitted through the radiator of the tube, causing the temperature of the detector to rise sharply, and the high temperature will affect the stability of the detector data. , leading to the degradation of final imaging quality and artifacts, and in CT equipment, other electrical components also generate heat, such as high voltage generators, PCB boards, etc.

In the prior art, in order to discharge the heat from the CT equipment and keep the internal temperature of the equipment stable, a cooling fan is usually added to the outer cover, and the heat inside the CT equipment is discharged through the rotation of the fan blades, and cold air is sucked into the CT equipment. Cooling, but there are some shortcomings in this heat dissipation method: multiple fans are required to work at the same time during heat dissipation, and the operation of the fans will generate a lot of noise, causing troubles to the use of medical staff and patients. At the same time, due to the large number of fans, the increase Increased installation difficulty, equipment cost and energy consumption, causing inconvenience to manufacturers and users
