Embodiment Construction

[0015] Now, an embodiment of the present invention will be described with reference to FIGS. 1 to 3 . In the drawings, front and rear, up and down arrows indicate directions when the air intake device integrated with the heat exchanger unit is installed in the vehicle.

[0016] Referring to FIG. 1 , a heat exchanger unit 10 is installed in an engine compartment of a vehicle (not shown) on a rear side of a front bumper (not shown) with a predetermined gap. Heat exchanger unit 10 includes: condenser 11 for vehicle air conditioning; radiator 12 for cooling engine coolant; electric fan 13 for causing air to flow through condenser 11 and radiator 12 ; and fan shroud 14 . The fan shroud 14 keeps the condenser 11 , the radiator 12 and the electric fan 13 in predetermined positions. The condenser 11 is arranged in front of the radiator 12 .

[0017] Vehicles typically have air intake openings (not shown) above or below the front bumper. An air guide duct (not shown) is provided bet...

Abstract

The present invention relates to an air-injection device which provides the entering air to the internal combustion engine of the vehicle, and the device is provided with an air filter unit, an entry pipeline and an outlet pipeline. The air filter unit is provided with an air filter outer shell, an air filter cover and an air filter element for purifying the entering air. The air filter outer shell is connected with the air filter cover together by the air filter element. The air inlet pipeline is connected to the air filter outer shell and is used for importing the entering air to the air filter unit. The outlet pipeline is connected to the air filter cover and is used for directing the entering air which is filtered by the air filter element to the engine. The outer shell of the air filter is molded integrated with the fan protecting grill of the heat exchanger unit to one module.

Description

technical field [0001] The present invention relates to an air intake device for introducing air into an internal combustion engine, and in particular, the present invention relates to an air intake device integrating an air cleaner unit with a fan shroud of a heat exchanger unit. Background technique [0002] In an internal combustion engine, since the temperature of the incoming air is low, the air filling efficiency increases and thus the torque increases. Therefore, it is known that air (outside air) that has not passed through a radiator and has a relatively low temperature is introduced as intake air into an internal combustion engine (hereinafter, referred to as an engine). For example, Japanese Unexamined Patent Publication No. 2000-257522 discloses arranging an opening of an inlet duct of an air cleaner unit at a front position to draw air not heated by a radiator. [0003] However, even in this configuration, the air may be heated by heat from the engine compartme...
