  • Cyclone cooler device
    Patent number: 11573053
    Abstract: A cyclone cooler device includes a housing that defines an interior channel elongated along a center axis. One or more of the fluid passage or configuration of an inlet end of the channel is shaped to induce a swirling flow of a cooling fluid within the channel while the channel is thermally coupled with one or more heat sources. The swirling flow of the cooling fluid removes thermal energy from and cools the one or more heat sources. During the swirling flow, the cooling fluid rotates around the center axis of the channel while also moving along the length of the center axis. The cooling fluid changes phases during the swirling flow to cool the heat source(s).

  • Heat exchanger
    Patent number: 11408686
    Abstract: A heat exchanger prevents cracking in heat transfer plates while avoiding lowering heat-exchange efficiency. Heat transfer plates are arranged with a space between them, and a hollow pipe extends through the plates. A high-temperature gas flows through the space to exchange heat with a liquid in the hollow pipe. The heat transfer plates are elongated in the direction in which parts of the hollow pipe are aligned and can thus have thermal expansion accumulating in the elongation direction. The heat transfer plates each include a thermal expansion absorber between an edge of the heat transfer plate receiving inflow of the high-temperature gas and an inter-pipe portion between adjacent parts of the hollow pipe to absorb thermal expansion of the heat transfer plate. A selected one or more of the inter-pipe portions, rather than all, include the thermal expansion absorber.
