The invention relates to the technical field of heat management of a low-vacuum pipeline ultrahigh-speed maglev train, in particular to a low-vacuum pipeline suitable for a high-speed train, a B groupof cooling assemblies are arranged on the low-vacuum pipeline, and each B group of cooling assemblies comprises a B group of cooling heat exchangers and/or a B group of nozzle assemblies which are arranged on the inner wall of the low-vacuum pipeline. The cleaning device has the advantages that: because the train runs at a high speed, gas friction in the train and the low-vacuum pipeline can generate a large amount of heat; meanwhile, key equipment in the low-vacuum pipeline can generate a large amount of heat and heat brought by other reasons in the pipeline when working; the B-group coolingheat exchanger and/or the B-group nozzle assembly are/is arranged on the inner wall of the low-vacuum pipeline and can exchange heat with gas in the low-vacuum pipeline, so that the cooling effect isachieved.
本发明涉及低真空管道超高速磁悬浮列车的热管理技术领域,尤其涉及一种高速列车适用的低真空管道,所述低真空管道上设置有B组降温组件,所述B组降温组件包括设置在低真空管道内壁上的B组冷却换热器和或B组喷嘴组件。该发明的优点在于:由于列车高速运行,列车和低真空管道内的气体摩擦会产生大量的热,同时,低真空管道内的关键设备工作时也将产生大量的热及管道内其他原因带来的热;本申请通过在低真空管道内壁设置B组冷却换热器和或B组喷嘴组件,可以与低真空管道内的气体换热,从而起到降温的作用。
