I'm a little slow today, but which way is the energy flowing? Or can it flow in either direction depending on the relative supplies of wind, solar, etc.?sophiecentaur said:
I remember my Dad describing a system with mercury arc rectifiers as switches in the cross channel (English) to France. Dc transmission was novel in UK at the time. Probably 1960s when UK and France tended to co-operate about things.berkeman said:
Heat dissipation tubes, also known as heat pipes, are components used in electronic systems and other applications to transfer heat away from sensitive parts to prevent overheating. They utilize the phase transition of a working fluid inside a sealed tube to efficiently manage heat.
Heat dissipation tubes work by exploiting the latent heat of vaporization of a liquid inside the tube. When one end of the tube, known as the evaporator, is heated, the liquid inside turns to vapor, absorbing heat in the process. This vapor travels to the cooler end of the tube, the condenser, where it releases the heat and condenses back into a liquid. The liquid then returns to the evaporator by capillary action through a wick or by gravity, completing the cycle.
Heat dissipation tubes are widely used in a variety of applications where effective thermal management is crucial. Common uses include in computer processors, high-performance GPUs, telecommunications equipment, aerospace components, and even in climate control systems to enhance energy efficiency.
Heat dissipation tubes are typically made from materials that have high thermal conductivity such as copper or aluminum. The choice of material depends on the specific requirements of the application, including thermal conductivity needs, weight considerations, and cost. The working fluid inside the tube is usually water, but in high-temperature applications, other substances like ammonia or acetone might be used.
Heat dissipation tubes offer several advantages over other cooling methods. They are highly efficient at transferring heat due to the phase change mechanism, which allows for rapid heat transfer over relatively long distances with minimal temperature difference. They are also passive, requiring no external energy input, which makes them reliable and maintenance-free. Furthermore, they can be designed to fit various geometries, making them versatile for different applications.
