High ground temperature tunnel cooling heat dissipation and heat energy conversion apparatus

Abstract

The invention discloses a high ground temperature tunnel cooling heat dissipation and heat energy conversion apparatus, comprising a cold water circulating cooling apparatus, a thermoelectric generation module and an accumulator electric set. The thermoelectric generation module comprises a thermoelectric generation cold end, a thermoelectric generation hot end, a heat insulation material, a lead, silicon semiconductors, germanium semiconductors and flow deflectors. The thermoelectric generation module is arranged between a cold water tank and a hot water tank; the thermoelectric generation cold end is in contact with the cold water tank; the thermoelectric generation hot end is in contact with the hot water tank; the heat insulation material is filled between the thermoelectric generation cold end and the thermoelectric generation hot end; the silicon semiconductors and the germanium semiconductors are in connection with the flow deflectors; cold water in a tunnel circulates in a pipeline to discharge high temperature heat quantity, thereby reducing the tunnel inner high ground temperature influence to a tunnel structure and the safety; cold water is changed into water with heat quantity, and enters the hot water tank; under the temperature difference effect of the cold water tank and the hot water tank on two sides, the thermoelectric generation module generates electric energy; the electric energy is stored in an accumulator set by employing the lead to supply power for an electric device.

Description

technical field [0001] The invention relates to the application technical field of cooling and heat dissipation and heat energy conversion, in particular to a cooling and heat dissipation and heat energy conversion device for high ground temperature tunnels. Background technique [0002] Driven by the rapid development of the national economy, tunnel engineering and other underground engineering have made continuous progress. Due to the needs of water conservancy and transportation, it is often necessary to construct deep tunnels, and high ground temperature has become an urgent problem to be solved in tunnel construction. Especially in many areas in the west of my country, due to the abundant geothermal resources, it is very easy to encounter the problem of high ground temperature in the construction of deep buried tunnels. For example, the maximum buried depth of Yunnan Gaoligongshan Railway Tunnel is 1155m, and the highest ground temperature reaches 60 degrees; Both the...

Problems solved by technology

[0003] At present, the treatment of the problem of high ground temperature in tunnels is only a single heat insulation and cooling treatment, such as sprinkling water to cool down, setting up heat insulation layers, cold water circulation, etc., but they have not made good use of the continuous energy of high ground temperature, which is undoubtedly a problem. a waste of resources
