A heat transport apparatus comprises an evaporator saddle having a pair of bores for housing two evaporators. The apparatus also comprises a condenser saddle having a pair of bores defining two condensers. One embodiment comprises a first loop heat pipe having a first condenser in fluid communication with a first evaporator, and a second loop heat pipe having a second condenser in fluid communication with a second evaporator. The two loop heat pipes share a single evaporator saddle and a single condenser saddle. A continuous conductance heat pipe may be placed in contact with either the evaporator saddle or the condenser saddle.
