  • Patent number: 11220915
    Abstract: A component wall of a hot gas component for a gas turbine, which in a double-walled design, has an outer wall which is hotter and an inner wall which is cooler during operation. The interior is divided by partition walls extending between the inner and outer walls. A coolant flows into the interior through inlet openings in the inner wall and out through outlet openings in the outer wall. An inlet cavity is directly connected to at least one of the inlet openings without being directly connected to outlet openings. A second cavity is provided directly next to the inlet cavity. The second cavity is directly connected, as an outlet cavity, only to at least one of the outlet openings, without being directly connected to inlet openings. The partition wall has at least one through-opening for conducting the coolant from the inlet cavity into the outlet cavity.

  • Patent number: 11172590
    Abstract: The disclosure provides a fluid driving device including a casing and an oscillation film. The casing has a fluid chamber, a liquid inlet, a liquid outlet, and a vent hole. The oscillation film is movably disposed in the fluid chamber so as to divide the fluid chamber into a liquid channel and a gas channel that are not fluid-connected to each other. The liquid inlet and the liquid outlet are connected to the liquid channel, and the vent hole is connected to the gas channel. When the oscillation film oscillates, it forces liquid to flow into the liquid channel from the liquid inlet and forces gas to flow out of the gas channel from the vent hole, or it forces the liquid to flow out of the liquid channel from the liquid outlet and forces the gas to flow into the gas channel from the vent hole.

  • Patent number: 10478790
    Abstract: The problem of providing a stirrer capable of more effectively shearing a fluid to be treated is addressed, by using the action of an intermittent jet stream. A stirrer is provided with a rotor having a blade and a screen, which are relatively rotated such that the fluid to be treated is discharged from the inside of the screen to the outside as an intermittent jet stream through a slit in the screen, the stirrer satisfying condition 1 and condition 2. (Condition 1) the relationship among the width b in the rotating direction of a tip part of the blade, the width s in the circumferential direction of the slit, and the width t in the circumferential direction of the screen member is b?2s+t. (Condition 2) the relationship between the width b in the rotating direction of the tip part of the blade and the maximum inner diameter c of the screen is b?0.1c.

  • Patent number: 10480872
    Abstract: A heat exchange tube combines an external surface feature, for example having crushed fins and cavities, which can have very high boiling enhancement characteristics, with an internal surface feature, for example having high performing intersecting helices, e.g. “cross hatched” with an intersecting helix angle. The new tube can provide a high performing tube in a shell and tube evaporator that can be relatively smaller, more efficient, and that can use relatively lower refrigerant charge.
