Description

Fitting and supporting structure of radiator

The present invention relates to an improvement in mounting support structure for common use of radiators for radiant cooling of engine coolant.

The temperature of the combustion gas in the cylinder reaches 2000 ° C or more, but not all of the combustion heat is converted into power, but a considerable amount of heat, about 30%, is absorbed by the cylinder, the cylinder head and the piston, resulting in heat loss.

However, if the temperature of each part of the engine rises excessively, the cylinder may be deformed or the cylinder oil film may be broken, resulting in poor lubrication. In severe cases, the engine may be stuck, and the combustion may be bad, resulting in knocking or premature ignition. Makes engine power lower.

For this reason, an engine cooling device is installed to cool the engine to prevent overheating and to keep the engine at a low temperature (when the engine is cooled too much, the thermal efficiency is greatly reduced). Water jacket, a water pump to circulate water into a cylinder, a radiator that cools the engine and releases the heat of the cooled coolant to outside air, a cooling fan to help forced ventilation of the radiator, and the coolant immediately after starting the engine. A water-cooled chiller composed of a thermostat for raising the temperature is used.

The radiator has a large heat dissipation area, and is a kind of tank that can hold a large amount of water. The radiator is composed of an upper tank, a lower tank, and a core part having a large heat dissipation area to quickly dissipate heat into the atmosphere.

The radiator is installed in front of the engine room so that the running wind generated when the vehicle travels can pass through the core portion to radiate and cool the coolant that has been heated.

However, since the radiator 20 is a very heavy structure, the inertia is large, and since many pipes through which the coolant passes are disposed, the radiator 20 is vulnerable to external shocks, thereby forming a vehicle body such that vibration noise does not occur as shown in FIG. 3. The radiator lower bracket 21 is mounted and supported via a rubber insulator 22, which is a buffer material of rubber material.

Accordingly, the vibration force is absorbed by the rubber insulator 22 when the radiator 20, which is a heavy object, vibrates up and down by the vibration of the vehicle, thereby preventing the vibration and noise from being transmitted to the interior of the vehicle to lower the riding comfort.

However, the above-described method is fixed because the fixing pins 23 inserted into the rubber insulator 22 are integrally formed in the lower tank 24, and thus the rubber insulators 22 cannot be used for different vehicle types. There was a problem in that it was a disadvantage in terms of cost burden.

In other words, the size, mounting position, and mounting structure of the radiator when designing a new car model are necessary items for the initial design, so it is necessary to check various items such as whether to share with other car models and to set the parts sharing and mounting structure. If the fixing pin 23 is different in the mounting position, the existing radiator itself cannot be used for other models with slightly different mounting specifications, resulting in an increase in cost in terms of inventory management. .

Accordingly, the present invention has been proposed in view of the above problems, and its object is to provide a mounting structure of a radiator which can be used by mounting a radiator in common regardless of a vehicle type.

In order to achieve the above object, the present invention is to support the radiator including the upper and lower tanks and the core portion to be mounted so as to be buffered to the radiator lower bracket via a rubber insulator,

An insertion groove formed at a bottom of the lower tank;

A fixing protrusion to be detachably inserted into the insertion groove to fix and fix a lower tank;

And a separable connection support member having the support protrusion fixed to the upper part to support the load of the lower tank, and having a support shaft inserted and supported by the rubber insulator to the bottom.

According to the second aspect of the present invention, an auxiliary rubber shock absorber for buffering and supporting the load of the lower tank is mounted on the upper surface of the detachable connection supporting member.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

1 is a view showing a radiator mounting structure according to the present invention, Figure 2 is a view showing a detachable connection supporting member according to the present invention.

The radiator (1) comprises a core (2) consisting of a thin tube through which the coolant passes and a cooling fin, a lower tank (3) which collects the coolant from the tube and sends it to the engine and an upper tank (not shown). On the bottom of the lower tank 3, an insertion groove 4 recessed toward the upper side is formed.

The insertion groove 4 of the lower tank 3 is fitted with a fixing protrusion 6 protruding from the upper portion of the detachable connection support member 5, and the load of the radiator 1 is applied to the detachable connection support member 5. It passes through the radiator lower bracket (7).

The fixing protrusion 6 is formed by a separate body and the separate connection supporting member 5, which is a main body, or is formed as a separate body, and is fixed by fixing means such as a screw 8 or integrally formed by welding as shown in FIG. do.

A support shaft 9 protrudes downward from the lower end of the detachable connection supporting member 5, and the support shaft 9 is formed in the hole 11 of the rubber insulator 10 mounted on the radiator lower bracket 7. It is fitted and supported.

An auxiliary rubber shock absorber 13 is mounted on the upper surface 12 of the detachable connection support member 5.

In the present invention as described above, when the vehicle vibrates, the load of the radiator 1 is transmitted to the lower radiator bracket 7 through the detachable connection supporting member 5, and vibration noise is attenuated by the rubber insulator 10 in this process. In addition, the vibration noise is also attenuated by the auxiliary rubber buffer 13 provided on the upper surface 12 to support the load of the lower tank (3).

However, since the radiator 1 manufactured as described above may be separated from the detachable connection support member 5, only the detachable connection support member 5 is changed when the mounting instruction position is changed when the radiator 1 is to be mounted on another vehicle. It is possible to apply the radiator 1 in common by changing the fabrication according to the specification.

According to the present invention as described above, the radiator is supported in the radiator lower bracket via a rubber insulator through a rubber insulator, so that the support position of the radiator varies depending on the vehicle type by supporting it via a detachable connection supporting member that can be separated from the radiator. Even though the radiator, which is an expensive structure, can be used in common through the adjustment of the detachable connection support member, it can bring about a cost reduction effect due to the use of parts.
