Embodiment Construction

[0021] Embodiments of the present invention are described in detail below.

[0022] Such as figure 1 , figure 2 and image 3 As shown, the tunnel anti-icing composite plate based on phase change material in the present invention is composed of six parts, which are outer shell 11, insulation layer 12, phase change material heat storage module 13, waterproof layer 14, deflector 15, Terminal 16. The outer casing 11 is a rectangular box structure, with an opening 111 on the upper side to sequentially put in the insulation layer 12, the phase change material heat storage module 13, the waterproof layer 14, and the deflector 15; the outer casing 11 is provided with terminals on both sides for assembly Groove 112, to put terminal 16 into. The thermal insulation layer 12 is provided with a rectangular groove 121 to accommodate the phase change material heat storage module 13 .

[0023] In this example, if figure 2 , the thermal insulation layer 12 is placed in the opening 121 ...

Abstract

The invention discloses a tunnel anti-icing composite plate based on a phase-change material. The tunnel anti-icing composite plate comprises an outer shell, a heat insulation layer, a phase change material heat storage module, a waterproof layer, a flow guide sheet and a wiring terminal, wherein heat stored in the phase change material heat storage module is released through the waterproof layer and the flow guide sheet so as to achieve the anti-icing and ice thawing effects. When the temperature of the phase change material is lower than a critical temperature T, a carbon fiber heating cable starts a heating mode; and the generated heat is directly transferred into the phase change material to realize phase change heat accumulation. The tunnel anti-icing composite plate has the advantages that the composite phase change material and the carbon fiber heating cable are combined; the intermittent heating, heat storage and ice thawing mode is realized; the initial cost and operation cost are reduced; and the anti-icing efficiency is improved. Meanwhile, the phase change material heat storage module, the waterproof layer, a heat insulation module and a system control module are combined and integrated; and the system structure is simplified, so that the installation is convenient, and the safety is improved.

Description

technical field [0001] The invention relates to a tunnel anti-icing composite board, in particular to a tunnel anti-icing composite board based on a phase change material. Background technique [0002] Tunnel icing is a cold area (the average temperature of the coldest month is -50 o C~-150 o C) and severe cold regions (-15 o Below C) the water flow in the tunnel and the water in the surrounding rock freeze, causing ice on the tunnel arch, ice on the side wall, ice on the network cable equipment in the tunnel, frost heaving of the surrounding rock, swelling of the lining, ice cones in the tunnel, freezing of the lines, etc. Affect the safe operation of trains and the normal use of buildings, and serious traffic accidents will also occur. Therefore, it is very important to adopt reasonable anti-icing technology for tunnels to reduce driving hazards and avoid traffic accidents. [0003] Tunnel icing is also a common problem in the world. At present, there are several treat...
