The invention discloses a circulation cooling system and cooling method of a vacuum pipeline maglev train. The circulation cooling system comprises a liquid cooling pipeline, a radiator, a coolant temperature control and feedback system, a coolant flow rate regulation system as well as a controller, wherein the liquid cooling pipeline is mounted in a train body high-temperature area of the vacuumpipeline maglev train; the liquid inlet end of the liquid cooling pipeline communicates with the liquid outlet end of the radiator; the liquid outlet end of the liquid cooling pipeline communicates with the liquid inlet end of the radiator; the coolant temperature control and feedback system is used for monitoring the temperature of a coolant in the liquid cooling pipeline in the train body high-temperature area, sending the coolant temperature information to the controller, and regulating the amount of the coolant discharged from the liquid cooling pipeline according to the temperature of thecoolant; and the coolant flow rate regulation system is used for regulating the flow rate of the coolant entering the liquid cooling pipeline according to the temperature of the coolant in the trainbody high-temperature area. Through the circulation cooling system and cooling method, the train body high-temperature area of the vacuum pipeline maglev train can be efficiently cooled.
Description
technical field [0001] The invention relates to the technical field of vacuum tube maglev trains, in particular to a circulating cooling system and cooling method for vacuum tube maglev trains. Background technique [0002] At present, the vacuum tube maglev train has received extensive attention due to its high speed, low resistance and low energy consumption. But the vacuum tube is a relatively closed space. When the train runs at a high speed, the aerodynamic heat generated around the train body continues to increase, which seriously affects the normal operation of the vacuum tube maglev train. [0003] Nowadays, with the continuous deepening of the development of the vacuum tube maglev train, it is found that when the train runs at a low speed, the heat generated around the train is relatively low, but when the train runs at a high speed in the vacuum tube, the heat generated around the train body extremely high heat. It can be seen that the heat dissipation problem of...
