Thermosiphon is a novel heat transfer element with exceptionally high thermal conductivity. Originating in the United States during the 1960s, a stainless steel water thermosiphon was successfully operated in Earth's satellite orbit in 1967. Once the thermosiphon theory was proposed, it garnered significant attention from scientists worldwide, leading to extensive research efforts. This rapid development of thermosiphon technology began primarily in the aerospace industry. China started researching thermosiphons in the 1970s and has been developing and utilizing them since the 1980s.
Operation Principle:
Heat pipes are made by filling steel, copper, or aluminum tubes with a thermal conductive medium, then evacuated to a certain vacuum and sealed. The working medium inside the tube is a mixture of various compounds, exhibiting extraordinary thermal activity and sensitivity; it absorbs heat and releases it when cooled. This superconductive working medium is activated at a certain temperature and transfers heat through a molecular vibration phase change. Its strong thermal conductivity results in a thermal conductivity coefficient about ten thousand times that of ordinary metals, with no temperature attenuation and the ability to transfer heat at an incredibly fast rate.
Features:
1. Excellent thermal conductivity: Fast, strong, and highly efficient heat conduction, with a reliable heat conduction speed that reaches the speed of sound.
2. Excellent Isothermal Performance: The excellent isothermal property allows the heat pipe to transfer a large heat flux under very small temperature differences, with low thermal resistance.
3. Heat flux variability: Heat pipes can alter the heating area of the evaporation section and the cooling section, meaning they can input a smaller heating area while outputting a larger cooling area, or vice versa, with a larger heat transfer area input and a smaller cooling area output.
4. Reliability: There is no overpressure within the tube. After the liquid working substance vaporizes, the internal pressure of the heat pipe does not change with temperature.
5. Environmental Adaptability: Heat pipes are not constrained by the environment and can be individually designed to meet the specific environmental needs.
6. Wide Application Scope: The shape of superconducting heat pipes offers greater flexibility, catering to a broader range of applications and the ability to withstand various harsh working environments.
Performance characteristics of heat pipe waste heat recovery:
Heat pipe waste heat recovery offers high heat transfer efficiency and significant energy-saving effects.
2. Flexible Installation and Layout: The structural design and placement are highly flexible, suitable for a variety of complex environments.
3. Longevity: With a lifespan of over 15 years, individual heat pipes are replaceable and removable, making maintenance simple and cost-effective.
Investment payback period is short: typically, the full investment can be recouped within six months to one year.
