Abstract
A system for heating a cabin of a vehicle can include: a liquid-cooled charge air cooler configured to receive a liquid, to receive heated air from one of a turbocharger and a supercharger of the vehicle, to cool the heated air via the liquid, thereby heating the liquid, to output the cooled air to an intake manifold of an engine of the vehicle, and to output the heated liquid; and a multi-function heat exchanger connected to the liquid-cooled charge air cooler, the multi-function heat exchanger configured to receive the heated liquid outputted by the liquid-cooled charge air cooler, to generate heated air via the heated liquid, and to output the heated air into the cabin of the vehicle, thereby heating the cabin of the vehicle.
Claims13
A system for heating a cabin of a vehicle, the system comprising:
- a liquid-cooled charge air cooler configured to receive a liquid, to receive compression-heated air from one of a turbocharger and a supercharger of the vehicle, to cool the compression-heated air via the liquid, thereby heating the liquid, to output the cooled air to an intake manifold of an engine of the vehicle, and to output the heated liquid, wherein the compression-heated air is heated by compression at the one of the turbocharger and the supercharger;
- and
- a multi-function heat exchanger interconnected with the liquid-cooled charge air cooler, the multi-function heat exchanger configured to receive the heated liquid outputted by the liquid-cooled charge air cooler, to generate heated air via the heated liquid, and to output the heated air into the cabin of the vehicle, thereby heating the cabin of the vehicle,
- wherein the multi-function heat exchanger is further configured to output the liquid which is received by the liquid-cooled charge air cooler, and
- wherein the liquid output from the multi-function heat exchanger is supplies to the liquid-cooled charge air cooler without passing through the engine.
A method comprising:
- receiving a liquid at a liquid-cooled charge air cooler disposed in a vehicle;
- receiving compression-heated air at the liquid-cooled charge air cooler from one of a turbocharger and a supercharger of the vehicle wherein the compression-heated air is heated by compression at the one of the turbocharger and the supercharger;
- cooling the compression-heated air by the liquid-cooled charge air cooler via the liquid, thereby heating the liquid;
- outputting the cooled air by the liquid-cooled charge air cooler to an intake manifold of an engine of the vehicle;
- outputting the heated liquid by the liquid-cooled charge air cooler to a switching unit through which the heated liquid passes;
- controlling the switching unit, thereby affecting a flow path of the heated liquid, in accordance with an operation mode of a plurality of predefined operation modes;
- and
- outputting the liquid, when having received the liquid in accordance with the operation mode, by a multi-function heat exchanger to supply the output liquid to the liquid-cooled charge air cooler without passing through the engine,
- wherein the multi-function heat exchanger is disposed in the vehicle and configured to generate heated air via the heated liquid and to output the heated air into a cabin of the vehicle thereby heating the cabin of the vehicle.
