National energy conservation and emission reduction schemes and application markets for heat pipes

First, the state attaches importance to the environment

First of all, China’s statement at the Copenhagen conference. Explosion-proof heat pipe radiators, the state first set limits standards for the four major industries, focusing on steel, non-ferrous metals, chemicals, building materials and other aspects. For example, small-scale enterprises with a steel construction area of 400 meters and backward iron-making blast furnaces, their unfavorable economic development and the state's attitude toward environmental pollution are confrontational, and the country resolutely rectifies and bans. At present, the country proposes that CO2 emissions will fall by 40%--45% in 2020 compared with 2005. Therefore, the above four industries are the focus of national rectification, energy conservation and consumption reduction to protect environmental pollution. At the same time, the state also promotes new energy power and new technologies.

Second, the state's support for new energy power and new technologies.

This can be echoed by the circular economy promotion law and the energy conservation law advocated by the state.

1, heat pipe

a, heat pipe introduction:

 A heat pipe is a novel heat transfer element with extremely high thermal conductivity. The heat pipe originated in the United States in the 1960s. In 1967, the first stainless steel water-water heat pipe was first put into the orbit of the Earth's satellite and successfully operated. The heat management theory was highly valued by scientists from all over the world. The research work has enabled the development of heat pipe technology. Heat pipe technology began to be mainly used in aerospace industry. China has been researching heat pipes since the 1970s. Since the 1980s, heat pipe gas-gas heat exchangers, heat pipe gas-water heat exchangers, heat pipe waste heat boilers have been developed. Heat pipe steam generators, heat pipe hot blast stoves and other heat pipe products make heat pipes widely used in building materials industry, metallurgical industry, chemical and petrochemical, power engineering, textile industry, glass industry, electrical and electronic engineering and other fields.

b, heat pipe working principle:

The heat pipe is made by filling the heat-conducting medium with steel, copper and aluminum pipes, and is sealed by a certain vacuum. The working medium in the pipe is made up of a mixture of various inorganic active metals and their compounds, and has super thermal activity and heat sensitivity. Sensual, sucking when exposed to heat, letting it cool. The thermal superconducting medium is activated at a certain temperature and transmits heat in a molecular oscillating phase deformation mode. Its super thermal conductivity makes its thermal conductivity 10,000 times that of a general metal, and the heat transfer temperature is not attenuated and can Passing at a very fast speed

c, heat pipe features:

(1), a wide range of work. Heat can be conducted in the temperature range of -30 ° C - 1000 ° C.

(2), safe and reliable. There is no overpressure in the tube and it is not afraid of dry burning. After the liquid working fluid is vaporized, the internal pressure of the heat pipe does not change with the change of temperature.

(3), easy to install. Not limited by the installation location, the heat pipe can be installed according to the design requirements, as long as there is a temperature difference to heat transfer.

(4), super thermal conductivity. The heat conduction speed is fast, the strength is high, the efficiency is high, and the transmission of the super heat pipe increases as the temperature difference increases.

(5), good isothermality. The heat pipe is input at 100 ° C on one end and 100 ° C at the other end. Good isothermality allows the heat pipe to transfer a large heat flux with a small temperature difference, and the heat transfer resistance is small.

(6), a wide range of applications. The ultra-thermal tube shape has greater flexibility and a wider range of applications to adapt to a variety of harsh working environments.

2. Application of heat pipes in new industries (farming, railway, etc.)

3. The application of heat pipes in waste heat boilers.
