    摘要: A cooling device for cooling a traction battery of a vehicle by means of a fluid. The device includes an evaporation device for installing in a housing body of the traction body, at least one condensation device for installing on the vehicle outside of the housing body of the traction battery, and connection lines which conduct fluid evaporated in the evaporation device to the at least one condensation device and condensed fluid from the at least one condensation device back to the evaporation device. The evaporation device, the at least one condensation device, and the connection lines form a first cooling circuit. The first cooling circuit is designed in the form of a natural circulation. The circulation of the fluid through the first cooling circuit includes the process of transporting gaseous fluid from the evaporation device to the at least one condensation device and liquid fluid from the at least one condensation device back to the evaporation device, and during operation the circulation is carried out on the basis of a difference in the density of the fluid evaporated in the evaporation device and the fluid condensed in the at least one condensation device and on the basis of a difference in the height of the at least one condensation device and the evaporation device.

    摘要: A method for producing hollow bodies made of plastics by blow molding or deep drawing using a deep-drawing tool or a blow-molding tool, comprising the extrusion of preforms from thermoplastics, the method comprising a wall thickness control of the preforms, wherein a measurement of the wall thickness of the preforms takes place within the tool on the mold cavity side on at least one reference point of a preform, the measured value obtained is compared as an actual value with a predetermined target value and the wall thickness control is triggered to change the wall thickness of the preform during extrusion or between extrusion cycles depending on the deviation between the actual value and the target value.

    摘要: A roof lining system for motor vehicles, has an air supply connection for connecting the roof lining system to an air conditioning unit of the motor vehicle and at least one outflow device which is in fluid connection with the air supply connection. The outflow device has a central outflow region and a peripheral outflow region, which each have at least one separate air supply channel. Each outflow device has at least two flow actuators, with a first flow actuator being assigned to the central outflow region and a second flow actuator being assigned to the peripheral outflow region. The first flow actuator is arranged in the air supply channel of the central outflow region, and the second flow actuator is arranged in the air supply channel of the peripheral outflow region, and in that the peripheral outflow region at least partially surrounds the central outflow region.

    摘要: The invention relates to a method for controlling the recovery of water in a motor vehicle, in which method, to recover water in an air-conditioning system (12) of the motor vehicle, air is cooled to a temperature below its dew point, and the water dropping out as a result of the cooling is collected in a water container (13). During water recovery, the air-conditioning system (12) is controlled by means of a water recovery control device (11), wherein, to control the water recovery by means of the water recovery control device (11), the air-conditioning system (12) is adjusted on the basis of at least one parameter value which is detected by a detection unit (10) and transmitted to the water recovery control device (11).

    摘要: A valve module for an operating fluid container system. The valve module has a housing which has a first connection for fluidically connecting to an operating fluid container interior, a second connection for fluidically connecting to a filler tube, and a third connection for at least indirectly fluidically connecting to the atmosphere. The valve module comprises the following features: the first connection is connected to the second connection and the third connection within the housing in a fluidic manner in each case; the second connection is connected to the third connection within the housing in a fluidic manner; and the first connection, the second connection, and the third connection can each be adjusted independently of one another between an open position, in which fluid communication through the respective connection is allowed, and a closed position, in which fluid communication through the respective connection is prevented.
