The invention provides a pipeline interval type heat dissipation method for a vacuum pipeline magnetic levitation transportation system, and the method comprises the steps that a plurality of heat dissipation assemblies are arranged at intervals in the length direction of a vacuum pipeline, and any heat dissipation assembly comprises an air cooling heat exchanger, a cooling device and a power unit; a plurality of temperature sensors are arranged in the direction of the pipeline at intervals; the air flow temperature is monitored in real time, when the air flow temperature of any area exceeds a set temperature threshold value range, the heat dissipation assembly in the corresponding area in the vacuum pipeline acts, the cooling medium absorbs the air flow heat in the corresponding area, the cooling device cools the cooling medium carrying the heat, and the cooled cooling medium is sent back to the air cooling heat exchanger again; and the process is repeated until the temperature is within a set temperature threshold range. By means of the technical scheme, the technical problems that in the prior art, due to pneumatic heat, an ultra-long-distance and ultra-large-pipe-diameter vacuum pipeline magnetic levitation transportation system is too high in environment temperature and poor in safety performance are solved.
Description
technical field [0001] The invention relates to the technical field of magnetic levitation transportation, in particular to a pipe interval cooling method for a vacuum pipe magnetic levitation transportation system. Background technique [0002] At present, the vacuum pipeline maglev transportation system is in the exploratory stage, and there is no ready-made experience for its pipeline heat dissipation technology. The choice of heat dissipation method depends on multiple factors, such as the total heat generated by the equipment, the allowable heat of the equipment, the working environment, the installation method and layout of the equipment, etc. According to the different heat dissipation capabilities, the main cooling methods are air cooling and liquid cooling, specifically as figure 2 shown. [0003] Air cooling is divided into natural cooling and forced cooling. Natural cooling refers to the use of heat transfer methods such as heat conduction, convection, and radi...
