Application of heat pipe air cooler

　　heat pipe air cooler is mainly used for power supply and coil system cooling of industrial electric furnace in casting, forging, heat treatment and other industries, because of its advantages of energy saving, consumption reduction, less investment and quick effect, it has been listed in the ""best energy saving practice case study"" by the energy saving information dissemination center of the State Economic and Trade Commission, and the application and benefit of the system are analyzed. Heat pipe air cooler is the 1 new type of cooling equipment that applies heat pipe technology to cooling systems. Its working principle is to pump a certain degree of vacuum inside the pipe, and then inject a certain amount of liquid (working fluid) and seal it, which is a heat pipe. Place the heat pipe vertically. If the lower part of the heat pipe is heated and the upper part is cooled, the working medium in the lower part will boil or evaporate, and the steam will rise to the cooling section. The cold wall will be condensed into liquid, and the latent heat of vaporization will be released at the same time. The condensed liquid will return to the heating section under the action of gravity to restart the evaporation and heat absorption process. In this way, the continuous transfer of heat is completed by the continuous phase change of the working medium in the pipe. The cooler consists of two parts: a water circulation system and a heat pipe system. The upper part of the equipment is a heat pipe bundle with fins. The finned tube side is equipped with a fan for heat dissipation. The lower end of the heat pipe bundle is placed in a water sink. The pipe pump sends the circulating water in the water tank into the water sink. The heat in the water is transferred to the fin part through the heat pipe blank, and the heat is dissipated by the fan, the cooled circulating water is sent out from the upper water pipe to cool the induction coil and the power supply system and enters the water tank through the return pipe, thereby completing the entire cooling process.

　　Compared with the pool cooling system, the equipment has obvious advantages: it has extremely high torsional heat coefficient, and the equivalent thermal conductivity can reach hundreds to thousands of times that of red copper; it has good isothermal characteristics, 2 meters long steel-water heat pipe, The working temperature difference between the hot end and the cold end is less than 3 degrees Celsius; the heat flux is high, and the heat transfer power of a single tube can reach tens of kilowatts; due to the use of closed circulation, pure water for circulating water, no scaling, and the amount of water compared with the cooling tower and pool cooling has greatly reduced; high reliability, simple operation, eliminating equipment maintenance and other problems. Through the analysis and on-site monitoring of the data and relevant data provided by electric furnace , which was selected as the case source, based on the average monthly steel output of 75 tons, the annual power consumption is 32960 kW hours (the average annual power consumption by pool cooling is 43800 kW hours), the annual power saving is 10840 kW hours, and the electricity cost is saved by 4878 yuan (calculated by Xi an electricity price of 0.45 yuan); Save water charges by 1741 yuan (calculated by Xian water price of 0.60 yuan); Save 9000 yuan for management and maintenance personnel and reduce carbon dioxide emissions by 11.4 tons annually. The total investment of the project is 20300 yuan. The payback period of the project investment is 1.34 years.
