Abstract: A method for operating a cooling unit that contains a slightly inflammable refrigerant is provided. The method is used with refrigerant circuit containing the slightly inflammable refrigerant and at least two shut-off devices that can be controlled by a computer, in which the computer closes the at least two shut-off devices thus dividing the refrigerant circuit into at least two separate segments when the cooling unit is switched off.

Abstract: A device, e.g., a heat exchanger, is disclosed. The device includes a first component and a second component. The first component has at least a first surface portion and a second surface portion. The first surface portion and the second surface portion are located opposite to one another and are spaced apart from one another. The first component includes a first support groove provided at the first surface portion and a functional groove provided at the first surface portion. The functional groove is arranged spaced apart from the first support groove at least in some sections. The functional groove is structured and arranged for partially receiving a second component for a substance-to-substance bond.

Abstract: The present disclosure concerns a method for embossing a component, a method for connecting a component to a second component via a substance-to-substance bond, and a device, e.g., a heat exchanger, having such a component. The method for embossing includes embossing a support groove into the component at least in some sections at a first surface portion of the component; embossing a functional groove into the component at the first surface portion; wherein the functional groove is arranged spaced apart from the support groove at least in some sections; and wherein the functional groove is formed for partially receiving a second component for a substance-to-substance bond.

Abstract: The disclosure relates to an actuator module at least consisting of an electrical machine and an application module. The electrical machine consists of a stator and a rotor, the rotor is slidably mounted directly on the stator, and the stator and the rotor are surrounded with plastic at least in the region of the inner bearing face. The plastic coating of the cylindrical rotor outer face has structures which extend as a spiral continuously over the height of the rotor.

Abstract: A system for cooling a mobile device within a vehicle is provided. The system includes mounting structure within the vehicle cabin, which can be a portion of the center console. The HVAC system of the vehicle provides forced air to the mobile device when the mobile device is mounted to the mounting structure. The system may include a supplemental passageway in which forced air will be provided toward a supplemental air outlet disposed adjacent the mounting structure. The mounting structure may include a movable flap that is biased to a closed position that blocks the flow of air out of the supplemental air outlet, and that moves to open the supplemental air outlet in response to mounting the mobile device. The mounting structure may include nubs on a base surface to space the device away from the base surface and allow air to flow around the mobile device.

Abstract: A dual DC-DC converter includes a controller signaling a plurality of switch sets for charging a first battery connected to a first DC output and a second battery connected to a second DC output. Each of the switch sets includes a high-side switch configured to switch a DC electrical input to a common node and a low-side switch configured to switch a ground to the common node. A filter capacitor is connected between each of the DC outputs and a ground. A mode switch is connected between the DC outputs and is opened to allow the dual DC-DC converter to be operated with each of the DC outputs having different voltages for independently charging the batteries at different states of charge. The mode switch is closed when the voltages on each of the DC outputs are equal or within a predetermined threshold.
