What isLHP
LHP(Loop Heat Pipe) is a hermetic closed-loop device filled withworking fluid. When LHP is operating, vapor is generated by heatingat the evaporator and flows to the condenser in which vapor iscondensed into liquid due to heat dissipation to the surrounding.Liquid working fluid then flows back to the evaporator throughconnecting pipe, and it is driven by capillary force induced by awick material inside the evaporator. Liquid is continuouslysupplied to the evaporator for evaporation again to complete acycle. The wick is made of porous material with micro pores to actas a powerful capillary pump for returning liquid from thecondenser.
Features of HeatDissipation Module for Electrical Devices There are several special features of LHP(1) Heat transport in long distance, may be severalmeters distance.(2) High power, as high as several hundreds Watts.(3) Flexible, bendable connecting pipe.(4) Anti-gravity operation, maintaining high heattransfer capability in anti-gravity direction.(5) Passive heat-transfer device, no external powerinput. We can help clients tosolve the thermal problem and also design customized product. Heat-Transfer Modelfor Street Lamp
Thestreet lamps made by ATD dissipate waste heat by using a majoradvantage of Loop heat pipe (LHP): it can transport heat in longdistance. As the model presents, the waste heat generated by theLED lamp (shown as “Heat source”) will be transported to the lampcase (“Cooling plate”) through the copper pipe (“Transmittingpipe”). By the contact of lamp case and air, LHP can circularlytransport waste heat and dissipate it to the surrounding by naturalconvection without extra power. Therefore, we can effectively solvethe thermal problems and extend the lifetime of LED lamps at thesame time.
Picture of Heat-TransferModel
Infrared RadiationDisplay of Street Lamp Application Take 100W Lamp for example, we can see how theheat is transfered to the lamp case through the Loop Heat Pipe(LHP)below:(1) LHP starts working, and heat quicklytransfers from Loop Heat Pipe to condenser L1, L2,L3.(2) With the increasing of heat moved,temperature between up-case and condenser L1, L2, L3 increasestoo.(3) Temperature in up-case increases withtime.(4) The temperature in the contact areabetween up-case and connecter starts todiffuse.(5) The temperature of the up-case and thecontact area between up-case and connecter will increase withtime.(6) Heat transfer system reaches steadystate.
