Description

Radiation prevention structure of radiator {PREVENTION STRUCTURE OF THERMAL DAMAGE OF RADIATOR}

The present invention relates to a thermal damage prevention structure of a radiator for a vehicle, and more particularly, by a thermal radiation radiator coupled to the exposed portion of the upper support of the radiator by a connection bracket, The present invention relates to a structure for preventing thermal damage of a radiator that prevents burns and can be used for various kinds of products.

Generally, an engine, a cooling device for cooling the engine, and an air conditioner are installed in an engine room of a vehicle. The cooling device includes a radiator for cooling the engine's cooling water and a fan shroud assembly that induces air flow to the radiator to increase the heat dissipation efficiency of the radiator surface and consequently promote the cooling water cooling efficiency. do.

The radiator may be classified into a down flow method and a cross flow method according to the flow direction of the cooling water.

The downflow method is a method of allowing the cooling water to flow from the upper tank to the lower tank by the own weight of the cooling water, and cooling the cooling water by a tube and a heat radiation fin formed between the upper tank and the lower tank.

In the downflow radiator, when the coolant moves from top to bottom through the tube, the driving force of the water pump and the potential energy of the coolant are combined to allow the coolant to pass through the tube at a high speed. In this case, a turbulent flow phenomenon occurs and a cavitation phenomenon occurs at the end of the tube, and bubbles may be formed in the coolant under the influence of such cavitation, thereby causing a problem that the bubbles flow into the engine.

The cross flow method applied to solve the above problems is a method in which the coolant flows in the lateral direction by the driving force of the water pump with the tanks in parallel, and a plurality of tubes are formed between the tanks formed on both sides. A plurality of heat dissipation fins are formed between the tubes.

1 shows a schematic front view of a conventional cross flow radiator.

Referring to the drawings, in the cross flow radiator 10, two upper and lower supports 15 and 15 'are arranged horizontally, two tanks 14 and 14' and a header 11 , 11 ') are arranged vertically.

The header is composed of a first header 11 and a second header 11 'that are spaced apart from each other left and right, and a plurality of tubes are disposed between the first header 11 and the second header 11'. (12) are combined. The heat dissipation fin 13 is interposed between the plurality of tubes 12 to expand the heat dissipation area.

The first tank 14 is coupled to the first header 11, and the second tank 14 ′ is coupled to the second header 11 ′, respectively. The first and second tanks 14, 14 'coupled to the first and second headers 11, 11', respectively, form a flow passage for the coolant, and the coolant flowing therethrough is a water pump (not shown). By circulating through the tube 12 by the driving force of, the heat accumulated in the cooling water is discharged to the outside air.

In addition, the support is composed of an upper support 15 connecting the first header 11 and the second header 11 'horizontally from the top and a lower support 15' connecting the horizontally from the bottom, It forms the outer structure of the radiator and serves to support a number of tubes and fins inside the radiator. The upper support 15 has a fan shroud engaging portion 16 formed with a coupling hole 17 for bolting to a fan shroud assembly (not shown) on both the left and right sides thereof, so that the fan shroud is located from the rear of the radiator. Allow the assembly to engage.

In the operation of the radiator 10, the cooling water discharged from the water jacket formed in the engine (not shown) of the vehicle is heated to form a cooling water inlet 14a formed at one side of the first tank 14. After flowing through and flowing through the tube 12, it flows out through the cooling water outlet 14a 'formed at one side of the second tank 14'.

At this time, the fan shroud assembly (not shown) is coupled to the rear of the radiator 10 so that the forced flow of air generated thereby accelerates the dissipation of heat in the radiator 10. The fan shroud assembly is bolted to the two tanks 14, 14 ′ and the two supports 15, 15 ′ at the rear of the radiator.

However, in the conventional cross flow radiator as described above, the upper support 15 of the radiator is exposed. The coolant flowing inside the radiator of the vehicle may be raised to a temperature of about 100 degrees Celsius. The high heat of the coolant is transferred to the support, so that when the user opens the hood of the vehicle, There was a risk of being burned by the part exposed to the outside.

In order to solve this problem, a structure for preventing a user's burn has been proposed by covering the exposed portion of the upper support of the radiator with an extension that is integrally injected with the fan shroud, but such a conventional structure has various types of fans. There was a problem in common with shrouds and radiators.

The present invention has been made to solve the above problems, by combining the thermal protection cover on the exposed portion of the upper support of the radiator with a connection bracket, to prevent burns of the user by the high-temperature radiator, to various kinds of products It aims at providing the thermal damage prevention structure of the radiator which can be shared also.
