Abstract

PURPOSE:To improve the heat exchange efficiency of an auxiliary cooling element, by providing an air inlet port in a part of a splash over. CONSTITUTION:Outside fresh air taken in through a front air inlet port 37 is guided to an auxiliary cooling element 41 by an upper panel 33, walls 9, 11 and a floor 19 to perform cooling by the air. After the cooling, the air is discharged to the outside through an air outlet port 39. The auxiliary cooling element 41 is thus always supplied with the cooling wind. The cooling element is not directly affected by a stone flipped during the movement of a vehicle, splashes, etc. A tongue is cut and erected at the air outlet port 39 so that negative pressure is very likely to occur near the port. According to this constitution, the efficiency of the discharge of the air is enhanced to improve that of intake of the air to heighten the cooling performance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for arranging cooling auxiliary parts of an automobile, such as an oil cooler and an intercooler.

[Prior Art] Conventionally, air-cooled cooling auxiliary equipment components such as an oil cooler for cooling hydraulic oil in an automatic transmission and an intercooler used in the turbocharger units 1 to 1 have generally been placed in the engine room. However, since the engine and power train are located inside the engine room, the temperature rises to such high temperatures that the heat exchange efficiency of cooling auxiliary parts deteriorates, and the degree of freedom in designing the engine room is restricted.
At worst, there was a problem that the vehicle body would become larger.

[Object of the Invention] Therefore, the present invention provides a cooling auxiliary component arrangement structure that can improve the heat exchange efficiency of the cooling auxiliary components and expand the degree of freedom of F+Q fi in the engine room. The purpose is to

[Detailed Description of the Invention 1 In order to achieve the above-mentioned object, in the present invention, a cooling auxiliary component is disposed in a space in front of the wheel formed by a hood ledge panel and a fender panel, and the cooling auxiliary component A splash cover is installed above, below, and between the hood ledge panels and fender panels above, below, and behind the machine parts to form a cooling auxiliary parts room, and an air intake is provided in the vehicle body in front of this cooling auxiliary parts room. By providing air intake ports in each part of the splash cover, the space within the engine room is not affected, and the cooling efficiency of the cooling auxiliary equipment components is improved.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 and 2.

In the figure, 1 indicates the engine room of automobile A. A hood 3 that can be opened and closed via a hinge (not shown) is arranged above the engine room 1, and
A cooling auxiliary parts chamber 7 is formed on the side of the engine 1 and in front of the front wheels 5.

The cooling auxiliary equipment parts room 7 is a room with walls on the top and bottom, front and back, left and right, and of the left and right side walls 9 and 11, the inner side wall 9 uses a hood ledge panel 9a, and the outer side wall 1
1 utilizes a front fender panel 11a. Further, the appetizer 13 uses the front apron 13a. Note that 15 is a bumper disposed above the front apron 13a via a stay (not shown).

On the other hand, the rear rear wall 17 and the lower floor wall 19 are connected to the hood ledge panel 19a and the front fender panel 11.
It consists of a splash cover S made of synthetic resin or metal that is installed between the space a, and the front end of the floor wall 19 arranged almost horizontally is fixed with screws 21 to the front apron 13a. Further, the rear end of the floor wall 19 is connected to the lower end of the almost vertical rear wall 17 which is screwed 25 to a splash cover 23 made of metal or synthetic resin (synthetic resin is shown in the figure) that covers the wheel house 29. Screw stopper 2
7 has been done.

Note that the rear wall 17 and the floor wall 19 may be formed of a single-piece splash cover S integrally formed with a continuous angular cross section.

The splash cover 23 has a rust-preventing function and is installed in the wheel house 29 of the wheel 5, and its front end and rear end extend forward and rearward of the wheel 5, respectively.

The upper wall 31 of the cooling auxiliary equipment compartment 7 has an upper panel 33 made of synthetic resin or metal that covers the front half of the upper wall 31.
and the splash cover 2 covering the latter half of the upper wall 31.
The upper panel 3 is formed by the front half 23a of the upper panel 3.
The front end of 3 is fixed to the front apron 13a with screws etc., and the rear end is fixed with screws 35 to the radiator air support panel 10 which is the front wall of the engine room 1 of the vehicle body A.
etc., and the upper panel 33 is fixed by
It serves as a support member that also serves as a bracket that supports the upper end side of the front apron 13a.

The cooling auxiliary parts chamber 7 is provided with an air intake port 37 for taking in cooling air and an air take-off port 39 for releasing the taken air to the outside. An air intake port 37 is formed in the front apron 13a at the front, and an air intake port 39 is formed in the floor wall 19 and rear wall 17 of the rear splash cover S, respectively. It has a blocking function to prevent direct intrusion into the cooling auxiliary parts chamber 7, and in this embodiment, - and have a shape with a tongue piece cut out in the direction of the vehicle [1]. Reference numeral 41 indicates an air-cooled cooling auxiliary component such as an oil cooler or an intercooler. It is fixed with screws or the like and placed in the cooling auxiliary equipment parts chamber 7. 43 indicates a headlamp, and 45 indicates a cross member.

In the cooling auxiliary equipment arrangement structure configured in this manner, air taken in from the front air intake port 37 is routed to the upper panel 33 and the side! 9, 11, fresh outside air is sent to the floor wall 19 and guided to the cooling auxiliary parts 41 side for cooling. Since the cooling auxiliary equipment parts 41 are configured to be discharged, they are constantly exposed to cooling air, and stones and splashes thrown up while driving are not directly affected. It is not directly affected by the heat of the air.Furthermore, the air outlet 39 has
Since the tongue piece is cut and raised, negative pressure is likely to be generated near the air intake port 39', increasing the air discharge efficiency, thereby improving the outside air introduction efficiency and increasing the cooling performance. It happens.

[Effects of the Invention] Therefore, according to the cooling auxiliary component arrangement structure of the present invention, it is possible to improve the heat exchange efficiency of the cooling auxiliary component, and there is no need to particularly arrange the cooling auxiliary component in the engine room. Therefore, the degree of freedom in designing the inside of the engine room is increased, and maintainability can be improved, and the engine room can also be made smaller, so that the size of the vehicle can be reduced. Furthermore, since there is no direct impact from splashes or flying stones during driving, the cooling auxiliary parts can maintain their functions in good condition.
