Advantages of heat pipe heat sink

Heat pipe heat sink is a kind of high efficiency heat dissipation device, which has unique heat dissipation characteristics.That is to say, it has high thermal conductivity, and the temperature distribution between evaporation section and cooling section is uniform and basically equal along the axis.

The thermal resistance of the heat sink is determined by the thermal conductivity of the material and the effective area within the volume. When the volume of a solid aluminum or copper heat sink reaches 0.006m cubed, increasing its volume and area does not significantly reduce the thermal resistance. For discrete semiconductor devices with dual cooling, the thermal resistance of air-cooled all-copper or all-aluminum heat sinks can only reach 0.04℃/W. The heat pipe heat sink can reach 0.01℃/W. Under the condition of natural convection cooling, the performance of heat pipe heat sink can be improved more than ten times than that of solid heat sink.

Heat pipe heat sink has the following advantages:

(1) thermal response speed, it transfers heat capacity than the same size and weight of copper tube is more than 1000 times;

(2) small size and light weight;

(3) high heat dissipation efficiency, LORI can simplify the heat dissipation design of electronic equipment, such as variable air cooling for self-cooling;

(4) do not need external power supply, work without special maintenance;

(5) has a good isothermal, thermal balance, the evaporation section and cooling section of the temperature gradient is quite small, can be approximately regarded as 0;

6 safe and reliable operation, does not pollute the environment.
