Soojuspippe

Soojuspippe is an Estonian term that translates to "heat pipe." It refers to a passive heat transfer device that uses phase change to transport heat. A heat pipe typically consists of a sealed tube containing a working fluid. The fluid is heated at one end, causing it to evaporate. The vapor then travels to the cooler end of the pipe, where it condenses back into a liquid, releasing its latent heat. The liquid then returns to the heated end via a wick structure, completing the cycle.

Heat pipes are highly efficient at transferring heat with very little temperature drop. Their effectiveness stems from the large amount of energy absorbed and released during the phase change of the working fluid. They are used in a variety of applications where efficient and passive heat transfer is required. Examples include cooling electronic components, solar thermal collectors, and spacecraft thermal management systems. The specific working fluid and materials used in a heat pipe depend on the temperature range and the heat transfer requirements of the application. Their simplicity, reliability, and lack of moving parts make them an attractive solution for many thermal challenges.
