US 2015/0176549 A1 · AIR INTAKE MANIFOLD

Abstract

An intercooler (5) is received in an intercooler receiving portion (6) of an intake manifold (1) leaving a given space therebetween and longitudinally opposed walls (10a, 10b) of the intercooler receiving portion (6) are formed with ribs (11) to increase a mechanical strength thereof, so that, even when a heat exchanging device (5a) of the intercooler (5) is set in the intercooler receiving portion (6) having longitudinally opposed walls thereof placed close to the longitudinally opposed walls (10a, 10b) of the intercooler receiving portion (6). undesired contact or interference between mutually opposed ones of the longitudinally opposed walls is suppressed permitting a larger amount of intake air flow through a major portion of the heat exchanging device (5a) thereby causing increased cooling efficiency of the intercooler (5).

1-4. (canceled)

A resin-made intake manifold having an intercooler receiving portion for receiving therein an intercooler,

in which the intercooler receiving portion is formed in a rectangular parallelopiped shape extending along a cylinder line direction of an engine and has an opening exposed to the outside of an outer surface of the intake manifold, one end part of the intercooler receiving portion being placed in the vicinity of an air inlet opening formed in the intake manifold,
in which of wall portions that constitute the intercooler receiving portion, wall portions placed at the one end part and the other end part in the cylinder line direction are formed, on inner surfaces thereof with ribs that project toward the inside of the intercooler receiving portion for suppressing interference of the inner surfaces with the intercooler, and
in which a clearance between the intercooler in the intercooler receiving portion and the intercooler receiving portion is set to a minimum value in such a range as not to bring about interference between the intercooler receiving portion and the intercooler while permitting a clearance between the intercooler and leading ends of the ribs to take a minimum value.

Dependencies are inferred from the claim text.
