Abstract:
1. A loop heat pipe, comprising: an evaporator to convert liquid phase working fluid into vapor phase working fluid; a condenser to convert vapor phase working fluid into liquid phase working fluid; a first vapor pipe and a first liquid pipe to allow the evaporator to communicate with the condenser and form a circular main loop; and a second vapor pipe and a second liquid pipe to allow the evaporator to communicate with the condenser and form a circular auxiliary loop, wherein the evaporator includes a reservoir that temporarily stores the liquid phase working fluid flowing from the first liquid pipe and the second liquid pipe, a first vapor collector that communicates with the first vapor pipe, a second vapor collector that is closer to the condenser than to the first vapor collector and that communicates with the second vapor pipe, a partition wall that separates the first vapor collector from the second vapor collector, a first wick formed from a porous member and disposed between the reservoir and the first vapor collector, and a second wick formed from a porous member and disposed between the reservoir and the second vapor collector.
