Abstract

The invention discloses a corrugated fin heat exchange structure for a mine air cooler and a design method of the corrugated fin heat exchange structure. The corrugated fin heat exchange structure comprises multiple rows of heat exchange pipes and a corrugated fin. The corrugated fin is a sawtooth-shaped corrugated plate. The heat exchange pipes in the two rows of adjacent heat exchange pipes are staggered. The corrugated fin comprises a plurality of corrugated fin units. Each corrugated fin unit comprises two symmetric strip-shaped plates. A heat exchange pipe laying plate for allowing one row of heat exchange pipes to be laid is defined by three adjacent strip-shaped plates. Heat transfer enhancement structures are arranged on the outer sides of the heat exchange pipes. The design method comprises the following steps that first, the size parameters of the corrugated fin are determined; second, the distances between any two adjacent heat exchange pipes are determined; and third, the size parameters of the heat transfer enhancement structures are determined. The corrugated fin heat exchange structure is reasonable in design, simple and convenient to process and manufacture, and good in using effect. The heat exchange pipes are arranged on the corrugated fin, and the heat transfer enhancement structures are arranged on the outer sides of the heat exchange pipes, so that the heat exchange efficiency can be improved effectively, the size of the mine air cooler can be reduced, and installation and arrangement of high temperature borehole operation places are facilitated.

Description

technical field [0001] The invention belongs to the technical field of heat exchange, in particular to a corrugated fin heat exchange structure for a mine air cooler and a design method thereof. Background technique [0002] At present, with the increase of coal mining depth and the improvement of mechanization, high temperature heat damage in mine working face has become one of the bottlenecks restricting deep mining, and seriously affects the life safety and work efficiency of operators. Mine air-conditioning is the main means of treating and controlling high-temperature heat damage. As the terminal equipment, the air cooler is the most important heat exchange component in the mine cooling system. Its flow and heat transfer characteristics have an important impact on the operating efficiency and stability of the cooling system. . The widely used arrangement form of air cooler is the tube-fin type. Due to the limitation of the thermal properties of the air outside the tube...
