Heat dissipating system and heat dissipating method for multifunctional CT machine

Abstract

The invention discloses a heat dissipating method for a multifunctional CT machine. The heat dissipating method comprises the steps that a rack is divided into a first part and a second part which are independent from each other, wherein a heating component CT bulb tube is located in the first part, and a liquid storage tank and the CT bulb tube are connected in the first part to form a circulation line; cooling liquid is injected into the liquid storage tank, a hydraulic pump is connected into the circulation line, the outer wall of the circulation line is wrapped by a semi-conductor refrigerator, cold air enters the first part through an air inlet, air subjected to heat exchange is discharged into the second part, and the air in the second part is discharged out of the rack through an air outlet. By means of the method, heat of the heating component CT bulb tube is dissipated quickly and reliably, the cooling liquid is used for absorbing the heat of the CT bulb tube to cool the CT bulb tube, the temperature of the cooling liquid in the circulation line is reduced through the cold end of the semi-conductor refrigerator, the absorbed heat is discharged through the hot end of the semi-conductor refrigerator, the cooling liquid flows in the circulation line through the hydraulic pump, and the effect of circularly dissipating the heat of the CT bulb tube is achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a heat dissipation system and a heat dissipation method of a multifunctional CT machine. Background technique [0002] CT equipment is a complex diagnostic system composed of X-ray emitting tubes, detectors, calibrators, high-voltage generators and many other sophisticated electrical and physical equipment. These electro-physical devices are mounted on a high-speed rotating turntable and sealed by a set of casings to avoid contact with doctors or patients. These electrical and physical devices mentioned above have very high requirements for their operating environment, for example, the temperature of the cooling oil in the bulb tube must not exceed 80 degrees, and the external temperature of the detector must not exceed 40 degrees. However, some components generate tens of kilowatts of heat during operation, such as bulbs, high-voltage generators, etc. If the...
