A waste-heat collection system for a vehicle is provided. The vehicle includes an internal combustion engine and an exhaust manifold via which exhaust manifold hot exhaust gas coming from the internal combustion engine is introduced into an engine-side segment of an exhaust system. The exhaust manifold and/or the engine-side segment of the exhaust system, an exhaust gas turbocharger and/or a catalytic converter are at least partially surrounded by a waste-heat collecting housing. Air contained in the waste-heat collecting housing is heated by waste heat of these components and the heated air is used to charge a latent heat accumulator.

A device and to a method are provided for using part of the heat given off by an internal combustion engine. A waste-heat-collecting housing surrounds at least part of an exhaust-gas manifold and/or at least part of an engine-side segment of an exhaust-gas system of the internal combustion engine. Air contained in the waste-heat-collecting housing is heated, and the heated air is used indirectly or directly to heat at least one of air that is introduced in a passenger compartment of the vehicle, cooling liquid of the internal combustion engine and oil in an oil circuit of the internal combustion engine. The waste-heat-collecting housing is similarly useable in a stationary apparatus having an internal combustion engine.
