Heat pipe

Heat pipe

●A conversion of the density of heat flow

●Fast heat-balancing

●Passive components


It is a special material with fast heat-balancing characteristics. It utilizes the vapor phase and liquid two-phase change of the material, and the convection principle to achieve multiple times of heat transfer than the metal heat conduction.


Working theorem

The first step of heatpipe processing is to remove the internal air then injects the working fluid and to seal. The vaporization temperature of the working fluid in the low pressure environment is greatly reduced. The evaporation zone absorbs heat and then vaporizes rapidly. The steam moves to the condensation zone. After exchanging heat with the external heat source, it condenses into a liquid state, and then flows back to the evaporation zone by gravity or pressure difference between the capillary wall and the wall, and the cycle is repeated. With the principle of two changes in fluid, the coefficient of heat transfer is about 50 to 100 times that of pure aluminum.

Vapor Chamber

●Horizontally conduction

●Passive components

●High stability

●Efficiency higher than heat pipe 10 times

Vapor chamber's function and working theory is same as heat pipe. In order to achieve a cycle working system, it works through the evaporation and condensation of the working fluid in the platy cavity. Vapor chamber is a product that can conduct a small part of heat source to a large area evenly and rapidly.


Cooling fan has been the major components of different kinds of industrial products, such as electrical machinery and electronic products which all requires cooling fan as the major device for thermal management. By creating the air flow, cooling fan provides cool air to lower the temperature of the industrial equipment, also, helps the industrial electric or electronic projects to keep the high efficiency and its performance will not be lowered due to the heat generated.
