Subway station load-bearing column heat radiation system using loop heat pipe and heat radiation method
The invention provides a subway station load-bearing column heat radiation system using a loop heat pipe and belongs to the field of underground space safety. According to the subway station load-bearing column heat radiation system using the loop heat pipe, with a tunnel load-bearing column as a carrier, tunnel emergency fire disaster as background, the problem that the load-bearing column collapses due to strength reduction caused by overheat within a short time in an emergency fire disaster is solved by using the loop heat pipe and a phase change material. The main parts of the subway station load-bearing column heat radiation system using the loop heat pipe comprise a liquid compensator, an evaporator, a liquid pipeline, a condenser coiled pipe, a phase change material layer and an underground municipal water supply network branch. When a fire disaster occurs in a tunnel, the phase change material layer, covering a column, of the subway station load-bearing column heat radiation system using the loop heat pipe absorbs instant heat; and meanwhile, a working medium in the evaporator buried in the phase change material layer absorbs the heat and transmits the heat to a condenser in a soil layer; the condenser coiled pipe is connected with the municipal water supply network branch; and water flow flowing in a pipe network takes away the heat. According to the subway station load-bearing column heat radiation system using the loop heat pipe, the collapsing, caused by fire disaster, of a subway station load-bearing column can be slowed and even avoided during the fire disaster to provide a precious time for follow-up fire-fighting and disaster-relief work and reduce property loss and personnel casualties.
一种应用环路热管的地铁站承重柱散热系统，属于地下空间安全领域。本发明以隧道承重柱为载体，以隧道突发火灾为背景，应用环路热管和相变材料解决因突发火灾，承重柱因短时间大量受热导致强度下降而坍塌的问题。主要部件包括液体补偿器、蒸发器、液体管线、冷凝器蛇形管、相变材料层以及地下市政供水管网支路。当隧道发生火灾时，本系统覆盖在柱子上的相变材料层吸收瞬间热量；同时，埋在相变材料层内的蒸发器中工质吸收热量传导至土层内的冷凝器，冷凝器蛇形管与市政管网支路连接，管网流动的水流带走热量。本系统在火灾时可以延缓甚至避免地铁站承重柱因火灾而坍塌，为后续灭火救灾工作提供宝贵时间，降低财产损失和人员伤亡。
