Description

Air-cooled heat conduction pipe and air-cooled split vacuum pipeline structure with same

Technical Field

The utility model relates to a vacuum tube way magnetic suspension traffic system technical field especially relates to an air-cooled heat pipe and have its air-cooled components of a whole that can function independently vacuum tube way structure.

Background

In order to reduce the running resistance, the wheels and the steel rails of the traditional railway traffic are eliminated, the levitation force and the guiding force of the vehicle are provided by using the magnetic levitation technology, and the traction force and the braking force are provided for the vehicle by using the linear motor. And in order to reduce the air resistance of the train running at high speed, the train is sealed in the pipeline, and the pipeline is vacuumized.

Compared with the conventional wheel track system, the magnetic suspension system needs to lay coils capable of providing suspension force, guiding force, propelling force and braking force on the track, the electric coils can generate large current when in operation, so that the coils can generate heat, and particularly the coils for providing the propelling and braking actions can generate more heat due to longer electrifying time. In the vacuum pipeline, the air density is very low (the vacuum pipeline is not completely vacuum, and thin air exists), the heat dissipation effect is very poor, and the working performance and the service life of the vacuum pipeline are affected due to overhigh temperature of the coil when the vacuum pipeline is used for a long time.

The vacuum pipelines in the prior art do not enter the engineering implementation and application stage worldwide, and from the disclosed information, all the vacuum pipelines do not consider how to radiate heat of the coil, and the heat generated by the coil is accumulated to a higher temperature when the vacuum pipelines are used for a long time, so that the insulation performance of the coil is influenced, and the service life of the coil is shortened.

In addition, the cross section of the existing vacuum pipeline is of a complete circular pipe structure, as shown in fig. 6 and 7, the vacuum pipeline of the circular pipe structure is not beneficial to improving the vertical rigidity of the cross section, the occupied area in the horizontal direction is large, the pipeline erection difficulty is large, and the construction investment cost of the vacuum pipeline is high.

From the above, the vacuum pipe of the prior art has several technical disadvantages.

First, the vacuum pipes do not consider how to dissipate heat of the coil, and heat generated by the coil is accumulated to a higher temperature when the vacuum pipes are used for a long time, so that the insulation performance of the coil is affected and the service life of the coil is shortened.

Secondly, the strength properties of concrete materials and steel materials are not fully exploited. The action load on the pipeline when a vehicle runs in the vacuum pipeline is mainly vertical, so that the section of the pipeline is required to have high bending rigidity in the vertical direction, the horizontal direction does not need too high rigidity, and the bending capacities of the whole circular steel pipe in the vertical direction and the horizontal direction are the same and unreasonable. In addition, the section geometry of the concrete part cannot be designed too high due to the limitation of the round pipe, more materials are distributed in the horizontal direction, the vertical rigidity of the pipeline is insufficient, the horizontal rigidity is excessive, and the strength performance of the materials is not fully utilized.

Thirdly, construction at elevated bridge sections is difficult. When the vacuum pipeline is used, the vacuum pipeline is made into a section with the length of dozens of meters, the vacuum pipeline is installed on a viaduct by using bridging equipment, the upper side of the pipeline of the whole circular pipe structure is arc-shaped, only one layer of steel plate is arranged, and the dead weight of a bridge girder erection machine cannot be borne, so that the engineering construction difficulty of the vacuum pipeline is high, and the problem of high construction cost is caused.

Fourth, the line built by such pipelines occupies a large area. Because the transverse and vertical dimensions of the circular tube are the same, the diameter of the circular tube must be increased in order to increase the bending vertical rigidity, and the increase of the transverse dimension increases the occupied area of the vacuum pipeline circuit, which causes the increase of the line construction cost.
