Problems solved by technology

[0004] 1. As an additional equipment of CT machine, the CT air cooler has no communication interface with the CT machine, and cannot directly obtain the rack temperature and status data from the CT machine: if the CT air cooler outputs too much cold air, the rack temperature will be too low , will affect the accuracy of the CT detector or cause other damage; if the CT machine is turned off and the CT air cooler continues to output cold air, it will cause a serious imbalance in the internal temperature of the rack, and the hot air in the rack may generate condensed water vapor and damage the circuit board when it is cold. ;
[0005] 2. If temperature sensors and other sampling components are installed inside the frame, the original structure of the CT machine will be changed or destroyed

Description

technical field [0001] The invention relates to the technical field of CT machines, in particular to a CT machine cooling system and a method for adjusting the air volume of the CT machine cooling system. Background technique [0002] A CT machine mainly includes a frame, a hospital bed, an operation console, and a CT tube and a detector assembly arranged in the frame. The CT tube is the X-ray source of CT and is a high-value consumable. The tube core of the CT tube is mainly composed of a filament, a rotating target disk and a vacuum chamber. The filament is heated to generate thermal electrons, which bombard the heavy metal target disk under the action of a high-voltage DC electric field to generate X-rays. When the CT tube is exposed, 99% of the electrical energy is converted into heat energy, and 1% of the electrical energy is converted into ray energy. The heat is absorbed by the insulating oil between the tube core and the shell, circulates through the oil circuit, e...
