  • Patent number: 8813689
    Abstract: A centrifugal fan with a pot-like impeller and with a housing, having a first circumferential wall region with an arc-like curvature which extends directly along the impeller. The housing includes in a direction of rotation of the impeller a second circumferential region with a radial distance from the impeller increasing spirally up to an outlet region. The housing includes in an opposite direction a third circumferential wall region extending to the outlet region, having an S-curvature and including a sub-region curved in the same direction as the first circumferential wall region forming a flow baffle element. Two side walls cover the axial end faces of the impeller wherein one of the side walls extends into the pot-like impeller and divides its interior into a first suction chamber having an intake and a second suction chamber. The outlet region expands in cross-section in the outlet flow direction.

  • Publication number: 20030217705
    Abstract: A vaporizer includes a pump for pumping liquid stored in a liquid store tank, a helical vaporizing tube, and a control system connected to two ends of the vaporizing tube for functioning to make the vaporizing tube produce high temperature so as to heat up swiftly liquid flowing through the helical vaporizing tube and finally vaporize liquid at the outlet end of the vaporizing tube, with the liquid in the helical vaporizing tube never reversely flowing back to the pump owing to low temperature of liquid at the inlet end of the helical vaporizing tube.

  • Patent number: 6591789
    Abstract: A high-speed and high-pressure injection heat-generating device is provided, and enables liquid injected at a high speed and under a high pressure to become heated by the force of the friction and resistance generated from the collisions of liquid molecules as passing through a heating generating unit, and thus the heated liquid can be used for the purpose of heating water. By connecting a liquid circulating pump to a liquid feeding tube through which source liquid is supplied to the heating generating device on the outlet side of the liquid circulating pump and providing a tube with bends in the heating unit, where the tube includes a plurality projections closely formed on an inner surface thereof, more heating efficiency can be obtained. Therefore, the heat generating device can provide a heating source or hot water thereby obtaining a high temperature efficiency in variety of fields such as heating and hot water supply, without consuming energy sources like oil or gas.

  • Patent number: 6427636
    Abstract: The invention relates to a method of heating a liquid medium by means of a first thermal system (2, 3, 4, 7, 12, 13) and at least one second thermal system (5, 6, 6A, 15, 16) following said first thermal system (2, 3, 4, 7, 12, 13), which thermal systems each have at least one heat exchanger (2, 5) through which the medium flows, and which second thermal system (5, 6, 6A, 15, 16) is operated at a higher temperature level than the first thermal system (2, 3, 4, 7, 12, 13). The method is characterized in that, for the accelerated raising of the temperature of the medium in the first thermal system (2, 3, 4, 7, 12, 13), the direct feed of the medium to the same is reduced and in the extreme case prevented, and in that medium flowing through the first thermal system (2, 3, 4, 7, 12, 13) is directed in a circuit. The invention also relates to a plant for carrying out the method.
