The invention relates to a heat exchanger for motor vehicles, comprising: a core (2) comprising a tube bundle of open ends stacked tubes (3) and comprising a top and a bottom extreme tubes (3a,3b); headers (4,5), each having a shaped flange (4a,5a) with corners (4b,5b) and being connected with open ends of the tubes (3,3a,3b); and side housing parts (6, 7) situated on opposite sides of the core (2) and extending at least partly between the extreme tubes (3a,3b) and between the header (4,5). At least one of the side housing parts (6,7) have at least one protrusion (10) projecting from the side housing part (6,7) in a corner thereof and bent to contact the side surface of the tube bundle; the at least one protrusion (10) has an external surface (10′) opposite to the tube bundle and formed into a shape matching the profile shape of the flange (4a,5a) of the header (4,5) in its corner (4b,5b); wherein the said external surface (10′) of the at least one protrusion (10) abuts the flange (4a,5a) of the said header (4,5) to ensure a liquid-tight connection of the header (4, 5) with the flange (4a, 5a) at the corner (4b,5b) thereof.

An engine includes: two cylinder rows so placed as to be aligned side by side; a turbocharger; and an intercooler shared by the two cylinder rows, and connected to the turbocharger. The intercooler has: a cool liquid flow path through which a cool liquid flows, and an intake air flow path through which intake air from the turbocharger flows. The cool liquid flow path has an inlet and outlet of the cool liquid on one side in a first direction along the flow of the cool liquid. The intake air flow path has an inlet of the intake air on one side in a second direction along the flow of the intake air, and an outlet of the intake air on another side.

An intake device for an internal combustion engine includes: a main pipe having an upstream end forming a suction port and a downstream end configured to be connected to an intake port of an internal combustion engine main body; a compressor of a supercharger provided in the main pipe; an intercooler provided in the main pipe at a position downstream of the compressor and including a cooling part, an upstream header provided upstream of the cooling part, and a downstream header provided downstream of the cooling part; a throttle valve disposed in the main pipe at a position downstream of the intercooler; a bypass pipe having a first end and a second end, the bypass pipe being connected to a part of the main pipe between the cooling part and the throttle valve; and a catch tank provided in the bypass pipe and configure to catch condensed water.

An apparatus for removing condensed water of an intercooler includes a collecting portion for collecting condensed water, the collecting portion being provided at a lower end of the intercooler; and an ultrasonic wave vibrator provided in the collecting portion, the ultrasonic wave vibrator being operated to introduce the condensed water collected in the collecting portion toward an engine so that the condensed water is vaporized, thereby removing or significantly reducing an amount of condensed water in the intercooler. The apparatus for removing condensed water of the intercooler can prevent engine damage and ignition failure due to the presence of the condensed water in the intercooler.

Disclosed is an air intake manifold including a heat exchanger built into its body and including at least two ducts for supplying and removing heat-exchange liquid, the ducts extending through the wall of the body of the manifold with a liquid-tight seal and an airtight seal, which are distinct and mutually offset along the longitudinal axis of the relevant duct being created on each of the ducts. The unit creating the liquid tight seal is arranged between the relevant duct and a circulation pipe connected to the free end of the duct. The unit creating the airtight seal is positioned between the relevant duct and the body of the distributor. A leakage path associated with the liquid-tight seal is created between the latter and the airtight seal.

Methods are provided for engines. In one example method, at higher engine load, cool compressed air is drawn into an engine via an air intake passage, and at lower engine load, ambient air is drawn into the engine via a duct while retaining cooled compressed air in the air intake passage. The compressed air may be released from the air intake passage based on heat transferred to the compressed air during the lower engine load, in at least one example.

An intercooler is a two-stage water-cooled intercooler having a first core and a second core. A condenser for an air conditioner includes a water-cooled condenser and an air-cooled condenser. A drive system electrical component such as an inverter, the second core, and the water-cooled condenser are cooled by a second cooling water circuit including a sub-radiator. Cooling is carried out by the second cooling water circuit including the sub-radiator. The sub-radiator and the air-cooled condenser are located in front of a main radiator.
