Abstract

A variable intake system for a vehicle to regulate an amount of intake air according to driving conditions of an engine may include an air cleaner connected to an intake duct which draws in intake air and forms a flow path for the intake air inside the air cleaner, a battery assembly installed in the flow path inside the air cleaner, which includes a plurality of cooling paths that allow the intake air to flow through the plurality of cooling paths, and a valve body installed in the air cleaner and selectively varying the flow path of the intake air.

First claim

What is claimed is:

1. A variable intake system for a vehicle to regulate an amount of intake air according to driving conditions of an engine, the system comprising:
an air cleaner connected to an intake duct which draws in the intake air and forms a flow path for the intake air inside the air cleaner;
a battery assembly installed in the flow path inside the air cleaner, wherein the battery assembly includes a plurality of cooling paths that allow the intake air to flow through the plurality of cooling paths; and
a valve body installed in the air cleaner, the valve body selectively varying the flow path of the intake air,
wherein a part of the intake air that is detoured toward the battery assembly is blocked by the valve body in a second driving condition of a second speed of the engine.

2. The variable intake system for the vehicle of claim 1 , wherein a part of the intake air is detoured toward the battery assembly through the valve body in a first driving condition of a first speed of the engine.

3. The variable intake system for the vehicle of claim 2 , wherein the part of the intake air that is detoured toward the battery assembly is blocked by the valve body in a second driving condition of a second speed of the engine, the second speed being higher than the first speed.

4. A variable intake system for a vehicle to regulate an amount of intake air according to driving conditions of an engine, the system comprising:
an air cleaner connected to an intake duct, wherein a flow path of the intake air flowing through the intake duct splits into a main path and a detour path;
a battery installing part positioned inside the air cleaner to form the detour path therein;
a battery assembly installed in the battery installing part, and including a plurality of cooling paths that allow the intake air to flow through the cooling paths;
a valve body installed between the main path and the detour path in the air cleaner and selectively fluid-connecting the main path and the detour path of the intake air;
a housing wall installed in the battery installing part to form an installation space therein, wherein an outlet is formed at the housing wall and fluid-connected to the installation space, and wherein the intake air passing through the cooling paths of the battery assembly is exhausted therethrough; and
a resonator including the detour path therein.

5. The variable intake system for the vehicle of claim 4 , wherein an outermost cooling path of the cooling paths is continuously fluid-connected to the main path.

6. The variable intake system for the vehicle of claim 5 , wherein diameters of the outermost cooling path in the main path and an innermost cooling path in the detour path is larger than diameters of remaining cooling paths of the cooling paths.

7. The variable intake system for the vehicle of claim 4 , wherein the air cleaner includes:
an intake inflow part integrally connected to the intake duct; and
an intake exhaust part configured to be connected to an intake system of the engine,
wherein the intake inflow part and the intake exhaust part are continuously fluid-connected through the main path and selectively connected through the detour path.

8. The variable intake system for the vehicle of claim 4 , wherein the battery installing part is provided as a resonator to decrease an intake noise.

9. The variable intake system for the vehicle of claim 4 , wherein an intake filter that removes foreign substances contained in the intake air passing through the main path and the detour path is installed inside the air cleaner.

10. The variable intake system for the vehicle of claim 4 ,
wherein a battery case formed with a plurality of sectioned cell spaces is included inside the battery assembly;
wherein a plurality of barriers are separately positioned at predetermined intervals inside of the battery case; and
wherein a cell space is formed between the plurality of barriers.

11. The variable intake system for the vehicle of claim 10 , wherein the cooling paths are formed on the battery case and on the barriers.

12. The variable intake system for the vehicle of claim 10 ,
wherein the cooling paths are formed on a bottom panel, on both a first side panel and a second side panel, and on the barriers of the battery case, which are mutually connected; and
wherein the cooling paths are formed extending from a front panel through a rear panel of the battery case along a flow direction of the intake air.

13. A variable intake system for a vehicle to regulate an amount of intake air according to driving conditions of an engine, the system comprising:
an air cleaner connected to an intake duct, wherein a flow path of the intake air flowing through the intake duct splits into a main path and a detour path;
a battery installing part positioned inside the air cleaner to form the detour path therein;
a battery assembly protrusively installed in the battery installing part towards the main path, wherein the battery assembly includes a plurality of cooling paths that allow the intake air to flow through the cooling paths; and
a valve body installed between the main path and the detour path in the air cleaner and selectively connecting the main path and the detour path of the intake air,
wherein diameters of an outermost cooling path disposed in the main path and an innermost cooling path in the detour path is larger than diameters of remaining cooling paths of the cooling paths.

14. The variable intake system for the vehicle of claim 13 , wherein a part of the cooling paths of the battery assembly are connected to the main path.

15. The variable intake system for the vehicle of claim 14 , wherein a remaining part of the cooling paths of the battery assembly are connected to the detour path.

16. The variable intake system for the vehicle of claim 13 , further including:
a housing wall installed in the battery installing part to form an installation space therein, wherein an outlet is formed at the housing wall and fluid-connected to the installation space, and wherein the intake air passing through the cooling paths of the battery assembly is exhausted therethrough; and
a resonator including the detour path therein.
