  • Patent number: 11145436
    Abstract: An assembled wire has a substantially rectangular cross section, and is formed by assembling a plurality of strands. Each strand has a conductor portion and a strand insulating layer covering the conductor portion. At least a part of the assembled plurality of strands in the longitudinal direction is covered with an outer insulating layer. The strand is formed as follows. First, the strand insulating layer is coated on the outer periphery of the conductor portion. A large number of voids are formed in a resin constituting the strand insulating layer. From this state, the strand is formed, for example, by collapsing the strand insulating layer by heating and pressurizing. At this time, it is possible to uniformly collapse the strand insulating layer by crushing the internal voids. Therefore, the voids in the strand are crushed and flattened in the thickness direction of the strand insulating layer over the entire periphery.

  • Publication number: 20200386489
    Abstract: An evaporator for use in a loop heat pipe includes an evaporator body, a heat receiving portion, an inflow portion, a discharge portion, a wick, and a partition. The evaporator body includes an internal space. The heat receiving portion forms an outer surface of the evaporator body to receive heat from an outside of the evaporator body. A working fluid condensed into a liquid phase by a condenser flows into the inflow portion in the internal space. The discharge portion is in the internal space, to discharge a gas-phase working fluid evaporated by the heat received by the heat receiving portion. The working fluid flowing into the inflow portion permeates into the wick in the internal space. The partition partitions the internal space into the inflow portion and the discharge portion with the wick. The wick is sandwiched between a surface of the partition and the heat receiving portion.
