1results about How to "Small temperature fluctuation range" patented technology

This utility model belongs to the field of heat dissipation technology, specifically relating to a loop heat pipe structure, including an evaporator, a condenser, and a liquid receiver. A liquid pipeline connects the condenser, liquid receiver, and evaporator, and the liquid pipeline contains a working fluid that circulates within the loop heat pipe structure. The evaporator is also connected to the condenser via a steam pipeline. A spiral guide vane is provided on the inner wall of the steam pipeline, and a cooling pipeline is coaxially fitted on the outer side of the steam pipeline to form a cooling channel. The cooling pipeline is connected to a cooling device and a circulating pump via a coolant pipeline. This utility model reduces steam flow resistance and improves condensation efficiency by setting spiral guide vanes within the steam pipeline. Especially in vertical pipe sections, it avoids localized overheating caused by steam stagnation. Furthermore, the cooling channel actively dissipates heat, preventing heat accumulation on the pipe wall and reducing the range of steam temperature fluctuations.
