Objective： To improve the CT bulb tube cooling rate and the testing method of the CT bulb tube temperature, and provide more stable platform for better bulb tube protection and longer life–span. Methods： The designed specified cold air machine could transfer the dry cold wind into machine rack, which can lower the ambient temperature of the machine rack and increase the air flow inside the machine rack and promote the efficiency of the heat exchange of the bulb tube oil cooling circuit. Results： the design of this system＇s joint is light and handy, which could collect the instantaneous temperature change of the bulb tube, and carry out simple manmachine interaction monitoring. Conclusion： According to the bulb tube oil-way temperature andambient temperature and relative humidity, the computer can dynamically adjust the refrigerating capacity and operation/cease of the air cooler. Then it can constitute the closed control loop, and accelerate the efficiency of the bulb tube＇s heat dissipation, and promote the heat capacity of the bulb tube equivalently.
