Heat pipe technology has revolutionized the cooling performance of DC computer fans. Heat pipes are highly efficient heat transfer devices that can quickly move heat away from the heat source.

A heat pipe consists of a sealed tube filled with a working fluid, such as water or a refrigerant. The tube has a wick structure on the inner wall. When heat is applied to one end of the heat pipe (the evaporator section), the working fluid inside the heat pipe vaporizes. The vapor, being less dense, rises to the other end of the heat pipe (the condenser section) where it releases the heat to the surrounding air and condenses back into a liquid. The liquid then returns to the evaporator section through the wick structure, driven by capillary action. This continuous cycle of evaporation, condensation, and liquid return allows for extremely efficient heat transfer.

In DC computer fans, heat pipes are often used to connect the heat source, such as a CPU or GPU, to the heat sink. They can effectively transfer heat from a concentrated heat source to a larger surface area of the heat sink, improving the overall cooling efficiency. For example, in a high - end gaming PC, multiple heat pipes may be used to connect the powerful GPU to the large - sized heat sink. These heat pipes can quickly transfer the intense heat generated by the GPU, ensuring that the GPU operates at a safe temperature even under heavy - load conditions.

Heat pipe technology also offers the advantage of flexibility in design. Heat pipes can be bent into various shapes to fit different computer case layouts and component arrangements. This allows for more efficient use of space inside the computer case while still maintaining excellent cooling performance.
