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

Disconnectable heat exchanger

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.

Device for cooling and heating a motor vehicle

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