Patent DE-19804567-A1 (DE)
Inventor: WOLF FRANZ JOSEF
IPC: G10K11/172
Filed: 1998-02-05
Abstract: The invention relates to a broadband surface absorber which is especially provided for absorbing interference noise from the acoustic frequency range in the atmosphere. The broadband surface absorber which operates according to the Helmholtz resonator principle is characterized by having an irregularly constructed lattice work whose connecting elements, with the narrow sides thereof, are aligned vertically in relation to the main surface of the aperture plate. The lateral edges of said connecting elements are, on the sound side, connected to the rear side of the aperture plate in an acoustic pressure-proof and fluid sealed manner and, on the rear side, are also connected in the same manner to a flat cavity delimitation, said delimitation being aligned in the same direction of the aperture plate, thereby forming differently matched chamber resonators.

IPC: F01P7/04
Filed: 1999-07-19
Abstract: A cooling device for a liquid-cooled IC engine (100) which makes use of a coolant comprises: a radiator (200) to cool the coolant which circulates between the engine and the radiator; a bypass opening (300) to supply the coolant which flows from the liquid-cooled engine out directly to the outlet side of the radiator, so as to go round the radiator in the bypass; and a flow control valve (400) with a bypass-side inlet (411) through which flows the coolant which passes through the bypass, a radiator-side inlet (412) through which flows the coolant that passes through the radiator plus an outlet (413) to output the coolant that flows in the flow control valve to the engine. The valve does all the above to control the bypass flow rate of the coolant that passes through the bypass opening and the cooling flow rate of the coolant that passes through the radiator, by changing the degree of opening of the flow control valve. The degree of opening of the flow control valve is controlled on the basis of a first temperature of the coolant that is output from the outlet, a second temperature of the coolant that flows through the bypass opening and a third temperature of the coolant which flows out of the radiator.
