A Tunnel Cooling Vehicle Convenient for Hot Air Collection

Abstract

The invention relates to a tunnel cooling vehicle which is convenient for collecting hot air, which comprises a vehicle jet fan, a quick cooling grid, a liquid outlet pipe, a liquid return pipe, a circulation pump, a heat exchanger and a closed refrigerator; the inlet end of the jet fan is connected to There is at least one intake pipe, and the servo motor drives the drive rod to rotate at a fixed axis to adjust the intake direction of the intake end of the intake pipe; the control device controls the servo motor according to the temperature detection data in the upper and lower directions of the two temperature detectors Adjust the intake end to rotate along the side with higher temperature; the circulation pump drives the heat exchange fluid to make a continuous one-way circulation flow along the heat exchanger, circulation pump, fast cooling grid, pre-cooling grid, liquid return pipe, and heat exchanger . The intake pipe can automatically adjust the suction direction, effectively absorb the hot air in the low-lying place and inject it tangentially into the jet channel to form a swirling airflow, which is conducive to the uniform, comprehensive and efficient cooling of the hot air, and the cold air shoots to the high place and drives the heat downward. The air forms a heat exchange cycle of cold and hot air, and the cooling effect is obvious.

Description

technical field [0001] The invention relates to the field of tunnel cooling equipment, in particular to a tunnel cooling ventilation device with low-humidity air supply. Background technique [0002] During the construction of railways and expressways, tunnel construction projects are often encountered. In the construction of tunnels, high rock temperature is often encountered, which leads to high construction environment temperature (the Sangzhuling Tunnel of Sichuan-Tibet Railway with the highest rock temperature currently encountered The rock temperature is 81.9°C). When the construction temperature is higher than the temperature in the tunnel of 28°C stipulated in the "Railway Tunnel Construction Code" TB10120-2002, the high ground temperature and heat disaster in the tunnel will reduce the labor capacity of the construction workers, have a great impact on health, and the incidence of altitude sickness will increase significantly, and mechanical equipment will fail. The...
