Heat Pipe
- Heat flow density change function
- Passive component
- Fast temperature uniformity
Heat pipe is a component that can quickly solve the single point of heating, using the two-phase change process of material vapor, liquid, and convection principle design. Strictly speaking, heat pipe can only be regarded as part of the heat dissipation device, and is a heat conduction element rather than a heat dissipation element. Its rapid temperature uniformity makes its application and popularity very wide and high.

Heat Dissipation Mechanism
The heat pipe process first removes the internal air and then injects the working fluid with a seal. The vaporization temperature of the working fluid drops significantly under low pressure. The evaporation zone absorbs heat and vaporizes rapidly. The vapor moves to the condensation zone, exchanges heat with the external heat source, condenses into a liquid state, and then flows back to the evaporation zone by gravity or capillary force and pressure difference of the tube wall, and the cycle continues again and again. By the principle of two-phase flow, the heat transfer coefficient is about 50~100 times that of pure aluminum.
Heat pipe is a special material with rapid temperature uniformity, and its hollow metal body makes it light. Its rapid temperature uniformity characteristic is designed by using the two-phase change of material vapor and liquid, and the principle of convection. Strictly speaking, the heat pipe can only be regarded as a part of the heat dissipation device and can be called a heat conduction element rather than a heat dissipation element. Its rapid temperature uniformity makes its application and popularity very wide and high. It has been widely used in various heat exchangers, coolers, geoheat uses, etc. It plays the role of fast heat conduction and is the most common and efficient heat conduction (not heat dissipation) element in the heat dissipation device of today's electronic products. For example, 5G related industries, cell phones, servers, etc., all have achieved better product performance due to the efficient thermal conductivity of heat pipes.
Thermal conductor element
Heat pipe is a heat conduction element, which is designed by using the two-phase change of material vapor and liquid and the principle of convection.
Large heat transfer, highly efficient
The heat transfer coefficient is about 50-100 times higher than that of pure aluminum.
Fast temperature uniformity
Compared with the forced air cooling path, the efficiency of the heat pipe can be increased by 50 times.
Use with a heat sink or fan
Although the heat pipe is efficient, it still needs to be designed as a module with a heat sink and thermal interface material to effectively reduce the temperature.
