  • Publication number: 20240298427
    Abstract: An in-vehicle device includes a housing, one or more coolers, and one or more turbulence generating members. The housing is attachable to a railway vehicle and accommodates an electronic component that generates heat. The one or more coolers are attached to and located outside the housing, with the one or more coolers thermally connected to the electronic component, to dissipate heat transferred from the electronic component to passing air occurring when the railway vehicle travels. The one or more turbulence generating members are located on a flow path of the passing air to cause turbulence by partly interrupting a flow of the passing air flowing to the at least one cooler.

    Abstract: A cooling device includes a heat-receiving block on which a heat emitter is mounted, a first heat pipe fixed at the heat-receiving block, and a second heat pipe located adjacent to the first heat pipe. The first heat pipe accommodates a first refrigerant in the gas-liquid two-phase state, and the second heat pipe accommodates a second refrigerant in the gas-liquid two-phase state. The ratio of the amount of the second refrigerant in the liquid state to the volume of the second heat pipe is higher than the ratio of the amount of the first refrigerant in the liquid state to the volume of the first heat pipe.
