Mouth connects described gas-liquid separator by an expansion valve, and the import of described condenser 4 connects described gas-liquid by a compressor and divides
From device
The heat exchange principle of heat pipe is, utilizes the continuous phase of internal working medium to complete the lasting transfer of heat, and self does not produces
Heat, has the highest heat conductivity and good isothermal.In heat pipe, vaporizer 3 working medium will be seethed with excitement or evaporation after being heated, and inhale
Receiving external heat source heat, produce the latent heat of vaporization, liquid become steam, the steam of generation under the effect of pressure reduction, flows in pipe
Condenser 4, steam is met cold wall face and external source, is condensed into liquid, release the latent heat of vaporization simultaneously, and pass to outside by tube wall
Low-temperature receiver, condensed fluid 4 can rely on action of gravity to be back to vaporizer 3 again to evaporate, and the most repeatedly, can realize passing outside heat
Pass and exchange.
In condenser 4, heat exchange area can be increased by fin, or increase heat-transfer surface by the quantity increasing copper pipe
Long-pending.Described condenser 4 can be air cooling water condensation device, and it uses diameter 0.7mm ~ 1mm(such as 0.8mm) copper pipe system
