Abstract: Device for exchanging heat between an acidiferous gas and a heat transfer medium, with at least one flow duct for the acidiferous gas which consists essentially of aluminum and/or an aluminum alloy.

Abstract: A method comprising a step of providing a cooling plate having at least one exposed cooling channel designed for guiding a cooling fluid. The method further comprises a step of providing a mounting unit designed for receiving and fixing at least one energy storage unit. The method finally comprises a step of connecting the cooling plate to the mounting unit, whereby the at least one cooling channel is closed.

Abstract: The invention relates to an air-conditioning system, in particular for a motor vehicle, in which a fan takes in air which flows through an evaporator and/or a heater, wherein the fan has arranged downstream of it an air-bypass channel, which contains a bypass damper and guides air past the evaporator. In the case of an air-conditioning system in which the air-mass flow which flows through the air-bypass channel and/or evaporator can be adjusted in a particularly variable manner, an air-throttle element is arranged in and/or on the air-bypass channel and/or upstream or downstream of the evaporator.

Abstract: The invention relates to a radial blower for delivering an air flow, having a drive motor, having a motor holder and having a fan impeller which has a hub bell at least partially overlapping the drive motor, wherein the fan impeller can be driven by the drive motor via an axially running shaft, wherein a surface, which faces toward the fan impeller, of the motor holder has flow-manipulating elements.

Abstract: A cooling device for a battery system may include at least two battery units. The cooling device may include at least a first and a second cooling plate able to be flowed through respectively by a coolant. The first and second cooling plate may be arranged respectively for thermal coupling with a respective battery unit. The first and second cooling plate each may include a first fluid inlet, which is connected fluidically with a first fluid outlet via a first fluid duct extending along an extent direction, and a second fluid inlet, which is connected fluidically with a second fluid outlet via a second fluid duct extending along the extent direction.

Abstract: A thermoelectric module may include a fluid-tight housing having at least one thermoelectrically active element arranged therein. The at least one thermoelectrically active element may have a coating. The housing may form an outer encapsulation and the coating may form an inner encapsulation for the at least one thermoelectrically active element.
