Problems solved by technology
[0002] With the increase of coal mine mining depth, the temperature of the underground working face continues to rise. When the mining depth exceeds 1 kilometer, the summer temperature can reach above 35 degrees Celsius, which seriously affects the health and work efficiency of workers. The traditional serpentine single-pipe radiator The length of the copper tube is long, the resistance of the fluid is large, and the heat transfer effect is poor

The invention discloses an evaporator for underground cooling. The evaporator for underground cooling comprises a shell, an air inlet, an air outlet, heat dissipation pipes, a main pipe, cleaning nozzles and a water baffle. An air inlet is formed in the left side of the shell, an air outlet is formed in the right side of the shell, the water baffle is installed on the air outlet, and the cleaningnozzles are installed in the air outlet and the air inlet. The heat dissipation pipes are evenly arranged along the inner wall of the shell, the two ends of each heat dissipation pipe are of double-helix structures, and the heat dissipation pipes are connected with the main pipe through pipelines. According to the evaporator for underground cooling provided by the invention, through the double-helix design, the length of a copper pipe is shortened, the fluid resistance is reduced, a heat exchange effect is better, and compared with an existing S-shaped single pipe, the wind resistance can be reduced, and the heat exchange efficiency is improved.
Description
technical field [0001] The invention relates to an evaporator for downhole temperature reduction, which belongs to the technical field of coal mining equipment. Background technique [0002] With the increase of coal mine mining depth, the temperature of the underground working face continues to rise. When the mining depth exceeds 1 kilometer, the summer temperature can reach above 35 degrees Celsius, which seriously affects the health and work efficiency of workers. The traditional serpentine single-pipe radiator The length of the copper tube is long, the resistance of the fluid is large, and the heat transfer effect is poor. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides an evaporator for downhole cooling. Through the double-helix design, the length of the copper tube is shortened, the fluid resistance is reduced, and the heat exchange effect is better, which is different from the previo...
