The present invention relates to a cooling device for an automobile, and more particularly, by mounting a cooling water inlet for connecting a cooling water flow hose between a radiator and an engine to an intake manifold side, thereby forming a gap (up and down height difference) between the top of the cooling device and the hood. Automotive cooling system that can maintain the level to satisfy pedestrian protection legislation, reduce vibration transmitted from engine to radiator through driver's seat, and guarantee design freedom for each configuration of cooling system It relates to a mounting structure.

The high temperature heat generated from the combustion chamber is transferred to the cylinder block, cylinder head, piston, etc. when driving the engine of the vehicle, which prevents the engine from overheating and increases the temperature of each component such as the piston or gasket above a certain temperature. It is well-known that cooling devices are installed to prevent them from becoming damaged.

Recently, the heat load of an engine increases with the increase of the output of an automobile engine, and with the increase of this heat load, the importance of the cooling performance of an engine becomes more important.

In general, a vehicle uses a water-cooled chiller that uses cooling water to cool the water. A water-cooled engine cooler, in which a coolant is circulated inside the engine and cooled, is cooled by a water pump. The engine is sent to the water jacket formed in the cylinder head to cool the engine, and then flows from the engine to the radiator through the coolant hose and cooled by the cooling fan or pumped back to the cylinder block by the water pump when the engine is not overheated. It is coming true.

4A and 4B, the conventional automotive cooling apparatus and its problems will be described as follows.

As shown in Figure 4a, the coolant return hose 101 for the coolant flow to be returned to the engine is connected to the upper end of the radiator 30, the coolant supply hose 102 for supplying the cooled coolant to the engine to the lower end of the radiator Is connected, and a separate cooling water inlet 10c is integrally mounted on the upper surface of the radiator tank.

At this time, the lower end of the radiator 30 is in a state substantially coinciding with the body underbody line, the coolant return hose 102 is arranged in the radiator side is lower than the engine side.

Meanwhile, recently developed vehicles must satisfy the pedestrian protection legislation of Europe, and in 2008, mass production vehicles must satisfy the pedestrian protection legislation step 1, and the pedestrian protection legislation step 1 is shown in FIG. The gap between the hood panel 32 covering the engine room and the parts in the engine room (the radiator's coolant inlet 10c), that is, the vertical distance is maintained at 60 mm or more, so that the buffing force does not touch the parts in the engine room when the pedestrian is hit. The provisions that make it possible to provide

However, the conventional cooling apparatus illustrated in FIG. 4A has the following problems because the conventional cooling apparatus shown in FIG. 4A cannot maintain a reference gap of 60 mm or more.

First, in the conventional cooling apparatus, the component located at the top of the hood outer panel is a cooling water inlet formed integrally with the radiator tank to satisfy the standard gap by lowering its formation position to satisfy the regulations. The size of the radiator tank and the core of the radiator Since the size can not be reduced, there is a concern that the cooling performance is deteriorated.

Secondly, since recently released cars tend to be gradually lowered in the line of hood panel covering the engine room to emphasize the agility with its exterior design, increase the hood panel to increase the gap with the coolant inlet and increase the reference gap. The satisfactory method causes the design freedom with respect to the hood panel.

Third, when only the position of the coolant inlet in the conventional cooling apparatus is lowered, as shown in FIG. 4B, the coolant return hose 101 has a lower radiator side in the cooling water circulation process of the vehicle cooling system, so that the engine side is higher and eventually returns to the coolant. Bubble discharge of the cooling water flowing through the hose 101 is not smooth, there is a problem that lowers the cooling performance of the vehicle.

Fourth, the cross flow (CROSS FLOW) type radiator has a disadvantage in that the design freedom is also reduced by fixing the nipple position when designing the hose for the flow of coolant.

In view of such a problem, the automotive cooling apparatus shown in FIG. 5A has been applied, and a separate coolant inlet 10b is provided so that it can be separately installed without forming a coolant inlet at the upper end of the radiator. It was possible to satisfy the reference gap with the hood panel 32.

That is, the engine side connector 103 is formed on the rear side, the lower end side of the writer tank side connector 104 is formed, the upper surface of the separate type of cooling water inlet 10b with a pressure cap 106 is a radiator ( 30) It was mounted lower than the upper end portion, so that the reference gap with the hood panel 32 could be satisfied.

However, as shown in FIG. 5B to which the vibration of the engine is attached, the radiator hose 101 → the separate cooling water inlet 10b → the body 28 at the portion where the radiator is mounted → the driver's floor panel (not shown) → steering. There is a problem in that it is delivered without filtration in the order of the wheel (not shown) to reduce the ride comfort.

The present invention has been made to solve the above-mentioned conventional problems, by mounting a cooling water inlet port connecting the cooling water flow hose between the radiator and the engine on the intake manifold side, the gap between the top of the cooling device components and the hood (up and down) Height difference) can be maintained to a level that satisfies pedestrian protection laws, vibrations transmitted from the engine through the radiator to the driver's side floor can be reduced, and design freedom of each configuration of the cooling system can be guaranteed. It is an object of the present invention to provide an automobile cooling device mounting structure.

The present invention for achieving the above object is characterized in that the cooling water inlet is connected to the cooling water flow hose between the radiator and the engine side to the engine, it is possible to maintain the gap between the components of the cooling device and the hood panel more than 60mm Provided is an automobile cooling device mounting structure.

In a preferred embodiment, the cooling water inlet is a pressure cap attached to the upper surface, the radiator tank side connector and the engine side connector is formed through the middle portion of the vertical bent form, the mounting plate having a mounting hole to be mounted to the engine Characterized in that formed integrally.

In a preferred embodiment, the mounting plate of the cooling water inlet is mounted on the upper surface of the intake manifold of the engine.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In order to satisfy the pedestrian protection regulations, the present invention can maintain the cooling performance of the radiator while maintaining the height difference (gap) between the hood panel and the radiator cooling water injection section, which is the uppermost part in the engine room, to 60 mm or more, which is the reference gap. The main point is that the damping effect of the engine vibration can be obtained, and the degree of freedom of design of each chiller component including a hose for cooling water flow can be improved.

To this end, the engine is equipped with a coolant inlet 10 to which the hoses 22 and 24 for cooling water flow between the radiator 30 and the engine, respectively, are connected. It is mounted on the upper surface of the fold cover 26.

Thus, as the mounting plate 20 is assembled to the upper surface of the intake manifold cover 26 of the engine by bolts inserted through the mounting holes 18, the cooling water inlet 10 is mounted, resulting in a hood. It is possible to attenuate the transmission of the engine vibration to the vehicle body while maintaining the vertical height difference (gap) between the panel and the coolant inlet 10, which is the uppermost part in the engine room, to 60 mm or more, which is the standard gap prescribed by the pedestrian protection law.

Here, looking at the operation of the engine vibration attenuated according to the structure for mounting the vehicle cooling apparatus according to the present invention.
