Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temperature control device in an automobile engine room.

[0002]

2. Description of the Related Art In a conventional automobile, active ventilation in the engine room is not performed, and accessory parts and the like that are affected by heat are exposed to high temperatures.

[0003]

For this reason, there has been a problem that auxiliary equipment parts and the like suffer heat damage such as temperature rise.

Therefore, an object of the present invention is to provide an engine room temperature control device capable of positively ventilating the engine room.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a duct for guiding outside air to an arbitrary position in the engine room of a vehicle, and the inside of the engine room is provided with the duct. It is characterized in that a switching valve for selectively guiding the warm air of is provided.

[0006]

Since the duct for guiding the outside air to an arbitrary position in the engine room and the switching valve for selectively guiding the warm air in the engine room are provided in this duct, the temperature in the engine room can be freely adjusted as necessary. It can be controlled.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 showing the inside of an engine room to which the present invention is applied, 1 is an engine room of an automobile, 2 is an engine, 3 is an exhaust manifold, and 4 is an engine.
Is an intake manifold, 5 is an injector, 6 is a body panel, 7 is a front grille, 8 is an outside air inlet,
Reference numeral 9 is a front bumper, 11 is a front skirt, 12 is an outside air introduction port, and 13 is a hood hood.

First, an engine 2 is horizontally arranged in an engine room 1, and an exhaust manifold 3 is connected to the front of the engine 2 and an intake manifold 4 is connected to the rear thereof. Intake manifold 4
An injector 5 is attached to the. Outside air inlets 8 are formed on the left and right of the front grill 7 in front of the engine room 1, and the front skirt 11 below the front bumper 9 also has a louvered outside air inlet 1.
2 is formed. A radiator and a cooling fan (not shown) are provided behind the outside air inlet 12 of the front skirt 11.

On the lower surface of the bonnet hood 13,
Left and right ducts 14, 14 connected to the outside air introduction ports 8, 8 of the front grill 7 are attached. That is, the duct 14 extends in the front-rear direction with the panel itself of the bonnet hood 13 as an upper surface, and forms the outside air outlet 15 that faces the injector 5 portion from above in the rear portion, and the exhaust manifold 3 portion in the lower surface of the intermediate portion. A warm air inlet 16 is formed to face above.

A control flap 17 which is a switching valve is incorporated in the warm air introducing port 16, and a warm air guide portion 16a is formed at the rear side of the warm air introducing port 16. The control flap 17 has a support shaft 18 on its front side.
Is supported on the front side of the warm air inlet 16 to open and close the warm air inlet 16 from above.
An actuator 21 such as a solenoid installed in the duct 14 is connected to the projecting piece 19 provided on the front side of 7.

With the above structure, the warm air inlet 1
6 is the state that the control flap 17 is closed,
The outside air from the front passes from the outside air introduction ports 8, 8 on the left and right of the front grill 7 to the ducts 1 on the lower surface of the hood 13
4 and 14, and the outside air outlets 15 and 15 at the rear part thereof
As a result, it flows to the injector 5 portion mounted on the intake manifold 4 behind the engine 2. Then, the control flap 17 is caused to operate by the operation of the actuator 21 based on the temperature information or the like by the computer.
When opening 6, the outside air inlet 12 of the front skirt 11
Enter from the radiator and exhaust manifold 3
The warm air that has cooled the air and the like flows into the left and right ducts 14 and 14 from the warm air inlets 16 and 16, and similarly flows out from the rear outside air outlets 15 and 15 together with the outside air.

Here, it is possible to appropriately change the mixing ratio of the outside air and the warm air in the duct 14 by the control flap 17, and to stop the flow of the outside air in the duct 14, and the like. The temperature in the engine room 1 can be controlled while appropriately controlling the flow of warm air. Incidentally, the specific structure of the outside air introduction port or duct and its outside air discharge port or warm air introduction port, as well as the switching valve, its actuator, etc. can be arbitrarily set in addition to the embodiment.

[0013]

As described above, according to the engine room temperature control device of the present invention, the duct for guiding the outside air to an arbitrary position in the engine room and the warm air in the engine room are selectively introduced into the duct. Since it is provided with a switching valve, the temperature in the engine room can be freely controlled as needed.
