Abstract:
The invention relates to a laminar flow water cooler (110) for a microprocessor comprising an integral radiator (112) provided with thin-walled and hollow fins which are produced by controlled compression of double convex bellows of a polymer or glass hot-blown blank. In order to form a closed circuit filled with water at the atmospheric pressure, the manifolds (113, 114, 115) of the radiator (112) are connected to the manifolds of an original component (114) formed by a mini heater (116) provided with a copper heating plate with internal grooved face and a mini pump (118) provided with a brushless electric motor devoid of a centrifugal turbine, wherein said mini heater and mini pump are disposed in a rigid small-sized moulded polymer hose.
Abstract:
The invention constitutes an arrangement for cooling a vehicle component, for example a transmission (2), disposed adjacent to an engine (1), which arrangement comprises a cooling circuit (8) designed to feed a coolant through said transmission (2) and comprising a line (16) for coolant to the transmission (2) and a line (17) for coolant to the transmission (2). According to the invention, said cooling circuit (8) is also designed to cool said engine (1) and comprises a further line (13) for feeding said coolant to the engine, and the cooling circuit (8) comprises a flow control valve (15) for controlling the coolant in the cooling circuit (8) such that the flow of coolant to the vehicle component (2) is lower than the flow to the engine (1). As a result of the invention, an improved arrangement is obtained for cooling, for example, a transmission, for example in heavy goods vehicles.
Abstract:
The invention relates to a cooling system for a motor vehicle, comprising at least one coolant pump (30), which is provided for circulating a coolant in the cooling system, and a main cooler (10), which has at least one main cooler inlet (11) and at least one main cooler outlet (12). The main cooler inlet (11) is connected at least temporarily to a coolant outlet (24) of a combustion engine to be cooled (20), while the main cooler outlet (12) is connected to a coolant inlet (23) of said combustion engine (20). According to the invention, at least one first aggregate (60, 80) to be cooled is connected parallel to the combustion engine and/or the main cooler (10).
Abstract:
The invention relates to a cooling fan (10), comprising a frame (12) which has a distributor device (14) to which an electromotor (16) is fixed, said electromotor driving a fan wheel (18). According to the invention, a control device (20) for the electromotor (16) is integrated into the frame.
Abstract:
Die Erfindung betrifft ein Verfahren zur Kühlung eines Steuergerätes(28)eines Fahrzeugs mit einem Verbrennungsmotor (4) und einer den Verbrennungsmotor (4) kühlenden Kühleinrichtung(10), die einen Lüfter (22) aufweist. Es ist vorgesehene, dass der Lüfter (22) das Steuergerät (28) in Abhängigkeit von einer ermittelten Steuergerät-Temperatur (T) mit mindestens einem Teil-Luftstrom kühlt. Weiterhin betrifft die Erfindung eine entsprechende Vorrichtung (44).
Abstract:
Die Erfindung betrifft eine Beleuchtungseinrichtung mit mindestens einer Leuchtdiode und einem Kühlkörper (1) zur Kühlung der mindestens einen Leuchtdiode, wobei der Kühlkörper (1) entweder mit Anschlüssen (13, 14) für einen Kühlmittelfluss durch den Kühlkörper (1) versehen ist oder die Beleuchtungseinrichtung zur Kühlung der mindestens einen Leuchtdiode mindestens ein Peltier-Element oder mindestens ein Heat-Pipe-Element umfasst.
Abstract:
The technique of the invention determines whether input data for driving and controlling a cooling fan have any abnormality (steps S100 and S110), sets an actual drive level F* of the cooling fan to a high level (Hi) in the event of detection of any abnormality (step S130), and controls a fan motor to drive the cooling fan at the set drive level F* (step S140). This arrangement effectively prevents a temperature rise to an abnormally high level in any of an engine and motors even in the event of any abnormality arising in the input data.
