Materials Of Copper Heat Pipes

Wiki Article

‌The materials of copper heat pipes are mainly high-quality copper and oxygen-free copper. ‌

High-quality copper is a copper material with high purity and good thermal conductivity. Its main components are copper (Cu) and manganese (Mn). Its electrical conductivity and mechanical properties are better than ordinary oxygen-free copper, and it is widely used in the manufacture of high-quality copper heaters. Oxygen-free copper refers to copper materials that do not contain oxygen in precision copper materials.

Its main components are copper (Cu) and a small amount of residual impurities. Oxygen-free copper has excellent thermal conductivity and good machinability, and is widely used in heaters, cables, transformers, conductive wires and other fields.

Advantages Of Copper Heat Pipes

The advantages of copper heat pipes mainly include the following aspects:

Excellent heat transfer performance: Copper has good thermal conductivity, which makes copper heat pipes more efficient in transferring heat and can quickly transfer heat from one end to the other.

Easy to weld: Copper is easy to weld, which can simplify the process and improve production efficiency when manufacturing heat pipes.

Corrosion resistance: Although copper is not as corrosion-resistant as stainless steel, copper heat pipes still perform well in non-corrosive liquid heating environments and can work stably for a long time.

Relatively low price: Compared with stainless steel heat pipes, copper heat pipes are usually cheaper, especially in some specific application scenarios, such as non-corrosive liquid heating, copper heat pipes are more cost-effective.

Composition Of Copper Heat Pipes
Copper heat pipes are mainly composed of the following parts:

Pipe shell: The pipe shell of a copper heat pipe is usually made of copper and has high thermal conductivity. The inside of the pipe shell is evacuated and a small amount of working liquid, such as pure water or ethanol, is injected.

‌Liquid wick: The tube is equipped with a capillary structure (liquid wick), which is usually made of fiber or fiber sinter. These wicks can absorb and store the working liquid. When the liquid evaporates, the wick draws the liquid back to the evaporation section through capillary action.

‌Working liquid: The working liquid (such as pure water, ethanol or naphthalene) filled in the tube evaporates when heated, and the vapor flows to the condensation section under the action of pressure difference. After releasing heat, it condenses into liquid, and then flows back to the evaporation section through capillary action to form a cycle.

‌End cap: There are usually end caps at both ends of the heat pipe to seal the pipe shell and prevent leakage of the working liquid.
