Patent ID: 8872071

Claim:
A welding implement coupleable to a power supply that is capable of delivering a welding current to the welding implement and imparting a thermal energy to the welding implement, comprising: a body having a proximal end and a distal end, the proximal end coupleable to the power supply; a head proximate the distal end of the body to receive the thermal energy imparted to the welding implement from the power supply; a heat pipe, the heat pipe having a closed passage contained within the welding implement, a casing surrounding the dosed passage, a wick covering at least a portion of an interior surface of the casing, and a vapor cavity located inside the casing and in communication with the wick, the casing to carry the welding current received from the power supply to the head, the heat pipe containing a working fluid in thermal communication with the head to extract at least a portion of the thermal energy from the head; and a fluid channel extending over at least a portion of an exterior of the heat pipe to receive a cooling fluid flowing from the proximal end toward the welding implement.
