Intercooler assembly
An intercooler assembly includes: a cooler body having a heat exchanger; an upper tank formed at an intake air inlet connected to the heat exchanger and coupled to an upper portion of the cooler body; a lower tank coupled to the lower portion of the cooler body to form an intake air discharge part connected to the heat exchanger; a bypass unit connected to the intake discharge part separately from the intake inlet; and a valve unit connected to the intake air inlet and the bypass unit and selectively introducing intake air supplied through a turbocharger into the intake air inlet and the bypass unit.
1. An intercooler assembly, comprising:
a cooler body having a heat exchanger;
an upper tank formed at an intake air inlet connected to the heat exchanger and coupled to an upper portion of the cooler body;
a lower tank coupled to a lower portion of the cooler body to form an intake air discharge part connected to the heat exchanger;
a bypass inlet unit which is integrally provided with an intake inlet unit through a valve mounting unit located outside of the upper tank and configured to form a passage partitioned separately from a passage of the intake inlet unit;
a bypass conduit configured to connect the bypass inlet and the intake air discharge part;
a valve housing having a main inlet connected to an intake inlet and the bypass inlet and mounted to the valve mounting unit; and
a valve body assembly installed in the valve housing and configured to selectively open and close a passage of the intake inlet and the bypass inlet by a driving force from an actuator,
wherein the valve housing is configured to form a first valve passage portion and a second valve passage portion connected to one main inlet portion,
wherein the valve body assembly includes:
a valve rotation shaft configured to traverse the first and second valve passage portions and connected to the actuator;
a first valve body fixed at a first location on the valve rotation shaft in the first valve passage portion; and
a second valve body fixed at a second location on the valve rotation shaft in the second valve passage portion, wherein the first location is spaced apart from the second location, and
wherein the first and second valve bodies are respectively provided in a form of a circular flap, and flat surfaces of the circular flaps of the first and second valve bodies are arranged to be perpendicular to each other, such that the flat surfaces of the circular flaps of the first and second valve bodies rotate together with the valve rotation shaft and respectively close or open the first and second valve passage portions at different rotation angles about a rotation axis of the valve rotation shaft.
2. The intercooler assembly of claim 1 , wherein:
the first valve passage portion has a predetermined passage cross-sectional area and is connected with the intake air inlet, and
the second valve passage portion has a passage cross-sectional area different from the passage cross-sectional area of the first valve passage portion and is connected to the bypass inlet.
3. The intercooler assembly of claim 2 , wherein:
the passage cross-sectional area of the second valve passage portion is smaller than the passage cross-sectional area of the first valve passage portion.
4. The intercooler assembly of claim 2 , wherein:
a central axis of the first valve passage portion is disposed closer to a central axis of the main inlet portion than the second valve passage portion.
5. The intercooler assembly of claim 1 , wherein the bypass conduit includes a condensate collector at a connection end connected to the intake air discharge part.
