Abstract: A heating exchanger (10) between a cooling conduit and an exhaust-gas line of an internal combustion engine includes a coolant inflow (26) and a coolant return (28) for coolant ducts (14), as well as an exhaust-gas inlet (30) and an exhaust-gas outlet (32) for exhaust-air ducts (36). The heat exchanger is arranged in a main exhaust-gas flow (34), and a shutoff device is provided in the coolant inflow (26).

Abstract: The current invention relates to an apparatus for cooling and/or heating a motor vehicle, with at least one coolant pump for circulating a coolant in a cooling and heating system, with a main cooler segment, which has a main cooler inlet and a main cooler outlet, wherein the main cooler inlet is at least intermittently connected to at least one coolant outlet of an engine to be cooled, in particular an internal combustion engine, of the vehicle, and its main cooler outlet is connected to at least one coolant inlet of the engine, and with at least one other, secondary cooler segment provided in addition to the main cooler segment and at least one other unit to be cooled, which is connected to the cooling and heating system, and the apparatus have at least one bypass line with a bypass valve, which is associated with the at least one secondary cooler segment and is disposed parallel to this secondary cooler segment in the cooling and heating system of the motor vehicle.

Abstract: The current invention relates to an apparatus for cooling and/or heating a motor vehicle, with at least one coolant pump (30, 32) for circulating a coolant in a cooling and heating system, with a main cooler segment (10), which has a main cooler inlet (11) and a main cooler outlet (12), wherein the main cooler inlet (11) is at least intermittently connected to at least one coolant outlet (24, 224, 225, 229) of an engine to be cooled (20), in particular an internal combustion engine, of the vehicle, and its main cooler outlet (12) is connected to at least one coolant inlet (23) of the engine (22), and with at least one other, secondary cooler segment (15, 215, 315, 415, 515) provided in addition to the main cooler segment (10) and at least one other unit to be cooled (60, 61, 70, 80, 90, 97, 170, 186), which is connected to the cooling and heating system.

Abstract: The present invention relates to a cooling device, in particular for cooling of components of power electronics, using a coolant which flows through a micro heat exchanger (10) having a good heat contact with the component (1), and wherein the coolant is selected in such a way that it evaporates in the micro heat exchanger (10) at the desired component temperature.

Abstract: A method and an apparatus for transporting thermal energy produced in a motor vehicle provides that the waste heat of an electronic component (42), such as a pulse-controlled inverter, be utilized to heat other vehicle parts, such as the internal combustion engine (12) or the passenger compartment. To that end, preferably two coolant circuits (10, 40) are provided, which can be coupled to one another or decoupled from another in order to control the flow of heat.

Abstract: The invention concerns a cooling system for a motor vehicle having at least one coolant pump (30) that is provided in order to circulate coolant in the cooling system, and having a main radiator (10) that has at least one main radiator inlet (11) and at least one main radiator outlet (12), whereby the main radiator inlet (11) is interconnected at least part of the time with a coolant outlet (24) of an internal combustion engine (20) to be cooled, while the main radiator outlet (12) is interconnected with a coolant inlet (23) of the internal combustion engine (20).

Abstract: The invention is based on a heat exchanger (10) between a cooling circuit and an exhaust-gas line of an internal combustion engine that comprises a coolant inflow (26) and a coolant return (28) for coolant ducts (14), as well as an exhaust-gas inlet (30) and an exhaust-gas outlet (32) for exhaust-air ducts (36).
