It is born from and swashs circulation and carry out work, while transmitting the latent heat and sensible heat of working fluid, the type of flow of internal working fluid can be with
The difference of heat pipe angle and change, mainly performance be exactly internal work liquid can be formed in the heating part of two sides it is dynamic
The scarce liquid compensating action of state.This is mainly the energy receiver and power source that evaporator is system, the heat being loaded on evaporator
Amount is transmitted to capillary wick core outer surface by evaporator shell first, so that liquid working substance is by thermal evaporation, and in capillary wick
The meniscus of vapour-liquid boundary is formed in the capillary of core.Due to the effect of capillary force, the steam generated in liquid-vaqor interface passes through steaming
Vapour channel flows into steam pipework, is finally condensed into liquid within the condenser, heat is transmitted to external heat sink by condenser tube wall.
The liquid working substance condensed out within the condenser under gravity, is flowed back into working medium liquid storage device, work by liquid line
Matter is promoted again by capillary wick from working medium liquid storage device to evaporator interface, is then absorbed heat, is steamed in evaporator again
Hair, flowing, and constantly the heat transfer in evaporator to the heat sink of distal end.
Due to the presence of loop, the flexible arrangement of heat pipe can have multiple evaporator sections and a condensation segment, and can 0 °~
It rotates and uses between 90 ° of any angles, overcome the phenomenon that single siphon heat pipe uses heat transfer deterioration near 0 ° of angle, increase
Its flexibility and adaptability for applying.
The heat-transfer capability of loop parallel type heat pipe radiator is 2~4 times big compared with siphon heat-pipe radiator, before same heat radiation power
It puts, volume ratio siphon heat-pipe radiator is small by 25% or more.
