Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a temperature control device in an engine room of an automobile.

[0002]

[Prior Art]

 In conventional automobiles, the engine room is not actively ventilated, and the heat-affected auxiliary equipment parts are exposed to high temperatures.

[0003]

[Problems to be solved by the device]

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

Therefore, an object of the present invention is to provide an engine room temperature control device capable of performing active ventilation in the engine room.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a switching valve that guides outside air to an arbitrary position in the engine room in a vehicle engine room and selectively guides warm air in the engine room into the duct. Is provided.

[0006]

[Action]

 A duct that guides the outside air to an arbitrary position in the engine room and a switching valve that selectively guides the warm air in the engine room are provided in this duct, so you can freely control the temperature in the engine room as needed. Is.

[0007]

【Example】

 An embodiment 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, 4 is an intake manifold, 5 is an injector, 6 is a body panel, 7 is a front grille, 8 is an outside air inlet, 9 is a front bumper, 11 is a front skirt, 12 is an outside air inlet, and 13 is a 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. An injector 5 is attached to the intake manifold 4. Outside air inlets 8 are formed on the left and right of the front grill 7 in front of the engine room 1, and a louvered outside air inlet 12 is formed in the front skirt 11 below the front bumper 9. A radiator and a cooling fan (not shown) are disposed 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, forms the outside air outlet 15 that faces the injector 5 portion from above in the rear portion, and forms 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 16 a is formed at the rear side of the warm air introducing port 16. The control flap 17 pivots a support shaft 18 on the front side thereof to the front side of the warm air introduction port 16 to open and close the warm air introduction port 16 from above. The protrusion provided on the front side of the control flap 17. An actuator 21 such as a solenoid installed in the duct 14 is connected to the piece 19.

With the above-described configuration, when the warm air inlet 16 is closed by the control flap 17, the outside air from the front flows from the outside air inlets 8 and 8 on the left and right of the front grill 7 to the lower left and right sides of the bonnet hood 13. Through the ducts 14, 14 of the engine, and from the outside air outlets 15, 15 at the rear portion thereof to the portion of the injector 5 mounted on the intake manifold 4 at the rear of the engine 2. When the control flap 17 opens the warm air inlet 16 by the operation of the actuator 21 based on the temperature information from the computer, it enters through the outside air inlet 12 of the front skirt 11 and cools the radiator and the exhaust manifold 3. The warm air flows into the left and right ducts 14 and 14 from the warm air inlets 16 and 16, and similarly, flows out together with the outside air from the outside air outlets 15 and 15 at the rear part.

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 so on. 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 inlet, the duct, the outside air outlet or the warm air inlet, and the specific structure of the switching valve, the actuator thereof, etc. can be arbitrarily set in addition to the embodiment.

[0013]

[Effect of the device]

 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 switching valve for selectively guiding the warm air in the engine room into the duct are provided. Because it is equipped, the temperature inside the engine room can be freely controlled as needed.
