Abstract
An integrated intercooler apparatus, which is supplied with intake air and recirculating exhaust gas, and cools the intake air and the recirculating exhaust gas, may include: a heat exchanger in which gas passageways through which the intake air and the recirculating exhaust gas pass and coolant passageways through which a coolant passes are alternately formed from a front side to a rear side thereof; and a variable device which controls an area of an exhaust gas supply region and an area of an intake air supply region at a front side of an inlet side of the heat exchanger.
Claims16
An integrated intercooler apparatus which is supplied with intake air and recirculating exhaust gas, and cools the intake air and the recirculating exhaust gas, the integrated intercooler apparatus comprising:
- a heat exchanger in which gas passageways through which the intake air and the recirculating exhaust gas pass and coolant passageways through which a coolant passes are alternately formed from a first side to a second side of an intake manifold;
- and
- a variable device which controls an area of an exhaust gas supply region and an area of an intake air supply region at a front side of an inlet side of the heat exchanger.
An engine system having an integrated intercooler apparatus which is supplied, from one side thereof, with intake air compressed by a compressor and recirculating exhaust gas which are recirculated, cools the intake air and the recirculating exhaust gas, and supplies the intake air and the recirculating exhaust gas to an engine,
- the integrated intercooler apparatus including:
- a heat exchanger in which gas passageways through which the intake air and the recirculating exhaust gas pass and coolant passageways through which a coolant passes are alternately formed from a front side to a rear side thereof;
- a variable device which controls an area of an exhaust gas supply region to which the recirculating exhaust gas is supplied and an area of an intake air supply region to which the intake air is supplied, at a front side of an inlet side of the heat exchanger;
- and
- a controller which is configured to control the variable device based on a driving condition.
