Description

Technical Field

[0001] The present invention relates to the field of fireproof partitions, and particularly to an automatic water-cooled lightweight fireproof partition for rail vehicles. Background Art

[0002] Although there are many fireproof rear walls for rail transit at present, most of them adopt aluminum honeycomb partitions or double-sided fireproof structures with fireproof boards. Although most of them can meet the fireproof requirements, there are great deficiencies in the overall heat insulation performance. If the overall fireproof performance can be achieved but the heat insulation performance is poor, it will cause a large amount of heat radiation, damaging the physical health of operators such as drivers, making it impossible for drivers to drive normally, and the subway vehicles cannot stop at a safe position, causing greater danger.

[0003] According to the fire resistance integrity requirements of EN45545, when the partition wall of a rail vehicle is burned to 800 °C on one side according to the standard, the integrity should still be ensured, and no flames should be visible on the other side. If a stainless steel plate is used to make the door, its weight is relatively large, which does not meet the lightweight requirements of rail vehicles. If aluminum alloy is used to make the door, the lightweight requirement can be achieved, but the melting point of aluminum is 660 °C. When the temperature reaches 800 °C, the aluminum will melt. Therefore, it is necessary to design a fireproof partition that can meet the requirements of lightweight and fire resistance integrity. Summary of the Invention

The second heat dissipation member has the same structure as the first heat dissipation member. The second heat dissipation member is a heat dissipation pipe with a heat dissipation medium flowing inside, and the heat dissipation pipes are arranged in a "J" shape along the vertical direction inside the movable partition door.

[0011] Further, the heat dissipation medium is water or water-cooling liquid. The two ends of the second heat dissipation member and the first heat dissipation member are respectively connected by a hose.
