- the present invention relates to ventilation systems for tunnel engineering, and more particularly, to a ventilation system configured for use in tunnel engineering and operated by a heat-driven cooling mechanism.
- Taiwan Due to its socioeconomic development, the densely-populated Taiwan has an inevitably great demand for electricity. In Taiwan, the dependency upon electricity is most markedly manifested in metropolitan areas and science parks. Hence, elevated high-voltage power cables play an important role in electric power transmission. However, in a city, high-voltage power cables have to work underground in order to let the city look neat and tidy and to prevent the high-voltage power cables from being damaged by an earthquake or typhoon.
- underground high-voltage power cables are confronted with problems, such as heat dissipation.
- Underground high-voltage power cables have to be installed in tunnels.
- tunnels are known to be less ventilated.
- high-voltage power cables in operation generate heat.
- the heat accumulated in tunnels that accommodate high-voltage power cables increases with the time of electric power transmission; as a result, the copper cores of underground high-voltage power cables are susceptible to damage, and the efficiency of electric power transmission by underground high-voltage power cables greatly deteriorates.

- FIG. 3 is a schematic view of operation of the ventilation system for use in tunnel engineering in the first embodiment of the present invention
- FIG. 4 is a schematic view of the ventilation system for use in tunnel engineering in a second embodiment of the present invention.
- FIGS. 5 and 6 are schematic views of operation of the ventilation system for use in tunnel engineering in the second embodiment of the present invention.
- a ventilation system 100 for use in tunnel engineering comprises a heat collecting device 10 and at least one piping system 20 .
- the ventilation system 100 is applicable to a tunnel 101 having at least one first shaft 102 and at least one second shaft 103 .
- the heat collecting device 10 collects heat.
- the heat collecting device 10 coupled with the piping system 20 , allows the temperature in the first shaft 102 to rise.
- the first shaft 102 manifests a chimney effect.
- the chimney effect speeds up convection between the air inside and outside the tunnel 101 .
- the heat collected by the heat collecting device 10 is the major energy source for driving the entirety of the ventilation system 100 .
- the heat thus collected may originate from solar energy, geothermal energy, fuel gas energy and/or waste heat. Any source of heat other than electric heat can be the source of heat collected by the heat collecting device 10 .
- the heat collecting device 10 comprises a heat collector 11 and a heat exchanger 12 .
- the heat thus collected originates from solar energy
- the heat collector 11 is a solar heat collecting panel or a solar vacuum heat collecting tube.
- the heat collector 11 absorbs solar radiation energy.
- the heat collector 11 is connected to heat exchanger 12 and stores, through the heat exchanger 12 , the absorbed thermal energy in the form of a heat transfer medium.
- water functions as a heat transfer medium, because water is characterized by high latent heat of evaporation, high stability, and no toxicity.
- Each said piping system 20 comprises a first pump 21 and a first pipeline 22 .
- the first pump 21 is connected between the heat collecting device 10 and the first pipeline 22 . Water is heated up by the heat collecting device 10 .

- the chimney effect means the enhanced natural convection between ascending hot air and descending cold air inside a vertical ventilation pipe.
- the heating spiral pipe 22 a speeds up the chimney effect taking place in the first shaft 102 , and enables cold air to be introduced into the tunnel 101 from the second shaft 103 , thereby achieving ventilation and renewal of air.
- the dashed-line arrows indicate the directions in which the hot water in the heating spiral pipe 22 a flows
- the white arrows indicate the directions in which gas flows. Due to the hot water introduced into the heating spiral pipe 22 a , the temperature of air inside the first shaft 102 rises, and thus the gaseous pressure inside the first shaft 102 rises. As a result, the air inside the first shaft 102 moves upward, and thus the air inside the tunnel 101 is guided out of the tunnel 101 . Since the air inside the tunnel 101 is discharged by means of the first shaft 102 , pressure inside the tunnel 101 drops. Eventually, ambient air enters the tunnel 101 via the second shaft 103 to thereby finalize a complete gas circulation process.
- the chimney effect is induced by the heating spiral pipe 22 a inside the first shaft 102 , such that air is discharged from the first shaft 102 and then fed through the second shaft 103 to thereby achieve ventilation and renewal of air.

- a portion of the first pipeline 22 and a portion of the second pipeline 24 coil inside the first and second shafts 102 , 103 to form the heating spiral pipe 22 a and a cooling spiral pipe 24 a inside the first and second shafts 102 , 103 , respectively, and the second pipeline 24 communicates with the second pump 23 to form a circuit.
- the cooling spiral pipe 24 a is made of metal or non-metal material.
- the ventilation system 100 ′ for use in tunnel engineering operates in a most-power-saving mode in different scenarios by taking account of extrinsic conditions.
- the dashed-line arrows indicate the directions in which the hot water in the heating spiral pipe 22 a flows
