Abstract:
Device for damping of sounds which comprises a casing (11 ) intended to be placed round one or more sou nd-generating equipment items, and a sound-damping panel (20) via which air is allowed to flow out from the casing. The sound-damping panel comprises a throughflow space (23) situated between a first wall (21 ) which faces towards the inside of the casing and a second wall (22) which extends along and at a distance from the first wall. The first wall is provided with a plurality of apertures (24) via which air is allowed to flow into the throughflow space. A diffuser means (25) is situated on the second wall directly opposite each aperture to deflect the air which via this aperture flows towards the second wall so that this air flow then proceeds in various different directions in the throughflow space. At least some of the internal surfaces of the throughflow space are covered with sound-absorbing material (29). Air is allowed to flow from the throughflow space and proceed to the surroundings via outlet apertures (31 ) of the sou nd-damping panel.
Abstract:
A cooling system (10) for a vehicle (14) includes a radiator (18) disposed on the vehicle and configured to receive airflow (F) through the radiator. A fan (24) is disposed on the vehicle (14) downstream of the radiator (18) with respect to the direction of airflow (F). An engine (12) is disposed on the vehicle (14) downstream of the fan (24), and an engine shield (26) is disposed on the vehicle downstream of the fan and upstream of the engine.
Abstract:
The present invention relates to a ventilating system for ventilating an engine space in a vehicle (1), the system comprising an enclosure (10) with walls (11), which encloses the engine space (18), at least one inlet (20) for entrance of air into the engine space (18), at least one outlet (23) for exit of air from the engine space (18) and a fan (16) being positioned outside the enclosure (10) and in fluid communication with the outlet (23) for providing a ventilating air flow (27) in the engine space (18) from said at least one inlet (20) to said at least one outlet (23) when the fan (16) is operated
Abstract:
A system for cooling a power source enclosure (34) may include a power source enclosure configured to substantially enclose a power source (12), and an airflow provider, located separately from the power source enclosure. The system may further include a conduit (50) configured to provide a fluid connection between a section of the airflow provider and an area inside the power source enclosure, wherein the conduit includes a first end (61) configured to terminate near the section of the airflow provider, such that during operation of the airflow provider a pressure differential exists at the first end, and a second end (62) configured to terminate on or within the power source enclosure.
Abstract:
A cooling system of a horizontal diesel engine digital generator unit is disclosed, wherein a main cooling ventilating cavity (A) of magneto is formed by a air-guiding cover, a cylinder cover and a box body (2) of the horizontal diesel engine; an upper air-guiding plate (3) of the cylinder, a lower air-guiding plate (4) of the cylinder and the box body (2) of the horizontal diesel engine are integrated; a left and a right main cooling ventilating cavities (B, C) are formed by the upper air-guiding plate (3), the lower air-guiding plate (4), the cylinder cover (11) and the box body (2); a main cooling ventilating cavity (D) in the bottom of the diesel engine is formed by the lower air-guiding plate (5), the engine side cover (6) and box body (2); and an additional cooling cycling cavity (E) of the silencer is formed by the side cover (6) and the rear cover casing (7) of a silencer.
Abstract:
Die Erfindung betrifft eine Kühlluftführung für einen in einem Motorraum angeordneten Verbrennungsmotor (6) einer Sattelzugmaschine (1) mit Frontlenkerfahrerhaus (2), umfassend wenigstens eine im Bereich der Sattelzugmaschinenfront (10) angeordnete Einlassöffnung (14) zur Zuführung von Kühlluft. Die Erfindung sieht vor, dass zur wenigstens teilweisen Durchströmung eines wenigstens den Verbrennungsmotor (6) aufnehmenden Motorraumes (4) mit einem Kühlluftstrom (26, 28) eine erste Strömungsverbindung (12) zwischen der wenigstens einen Einlassöffnung (14) und dem Motorraum (4) und eine zweite Strömungsverbindung (16) zwischen dem Motorraum (4) und wenigstens einer im Bereich einer Rückwand (18) des Fahrerhauses (2) in die Umgebung mündenden Auslassöffnung (20, 22) vorgesehen ist.
Abstract:
Amphibious vehicle (3) has one or more ducts (9) running from a first to a second end of the vehicle; from vent (5) to vent (7), or vice versa. The vehicle prime mover (19), transmission brakes, and / or electronic controls, may be cooled in the duct. Fan (19) draws or blows air through the duct. The hull may comprise one wall of the or each duct; hull surface coolers may be provided for cooling liquid. The duct(s) may pass through one or more bulkhead(s) (11, 13) of the vehicle. A separate engine cooling system may comprise a radiator (23) and fans (29). The marine drive may be a jet drive; the vehicle road wheels (6, Figures 4 and 6) may be retractable above the vehicle water line when the vehicle is in marine mode.
