The present invention relates to a radiator, and more particularly, to a radiator capable of simplifying the drain hole configuration for discharging the cooling water, and easily discharging the cooling water inside the radiator to the outside, preventing leakage and reducing the manufacturing cost.

In general, in a vehicle equipped with an internal combustion engine, heat generated during engine operation is conducted to a cylinder head, a piston, a ball, and the like. When the temperature of these parts becomes excessively high, the strength of the parts decreases due to thermal expansion or deterioration. The service life is shortened, the combustion condition worsens, knocking or premature ignition occurs, and the output of the engine is reduced.

In addition, when the engine is incompletely cooled, the oil film on the inner circumferential surface of the cylinder is broken, and the lubrication function is degraded. Also, the engine oil is deteriorated, which causes abnormal cylinder wear and the piston is fused to the inner wall of the cylinder. do.

Therefore, in order to cool such an engine, an automobile is usually provided with a water cooling chiller.

The water-cooled cooling device is to lower the temperature while the coolant circulates the cylinder block and the cylinder head by a water pump, and is provided with a radiator, a cooling fan, and a water temperature controller for heat dissipation of the coolant.

The radiator is a device for dissipating and cooling the coolant whose temperature has risen while passing through the engine, and a perspective view of a conventional radiator is illustrated in FIG. 1. In brief, the radiator 1 is briefly spaced vertically and ends at both openings. A plurality of tubes 13 are connected in parallel so that cooling water flows between the upper and lower header tanks 10 and 11 to which the cap 12 is coupled, and the heat transfer area is widened between the tubes 13. The heat dissipation fins 14 for heat-exchanging the cooling water passing through the tube 13 are fixed, and the deformation of the tube 13 and the heat dissipation fins 14 is prevented between both ends of the upper and lower header tanks 10 and 11. The side support 15 is assembled so that it can be carried out.

In addition, a cap 16 is installed at the upper header tank 10, and a valve packing (not shown) and a spring (not shown) capable of selectively opening and closing a flow path in accordance with the internal pressure of the radiator 1. Not shown) is installed.

In addition, the upper and lower header tanks 10 and 11 are provided with inlet and outlet pipes 17 and 18 connected to the hoses 19 and 19a to allow the coolant to flow in and out.

Therefore, the coolant heated while passing through the engine is introduced into the upper header tank 10 along the hose 19 and gradually cooled while performing active heat exchange with the outside air through the tube 13, and then the lower header tank ( 11) it is discharged to the hose (19a) to be introduced into the engine again to repeat the cooling of the overheated automobile engine. Then, when the internal pressure of the radiator 1 rises, the flow path formed in the cap 16 is opened so that the coolant flows out into the reservoir tank (not shown). On the contrary, when the internal pressure decreases, the coolant flows from the reservoir tank. .

And, as shown in Figure 2, one side of the lower header tank 11 of the radiator 1 is provided with a drain port 11a having a screw portion formed on the inner circumference to discharge the cooling water inside the radiator 1 to the outside The drain plug 20 is fastened by screwing to seal the drain port 11a. In other words, when the coolant is used for a long time, it is necessary to periodically change the coolant because scale is generated in the flow path. At this time, when the drain port 11a is opened by removing the drain plug 20, the coolant inside the radiator 1 is discharged to the outside.

However, as the drain port 11a is separately formed in the lower header tank 11 and the drain plug 20 is coupled thereto to simply discharge the cooling water to the outside, the number of parts and the manufacturing process are increased, thereby increasing the manufacturing cost. There is a problem.

In addition, when the drain plug 20 is damaged near the screw portion, the drain plug 20 cannot be easily removed from the drain port 11a, and thus, it is difficult to discharge the cooling water to the outside.

An object of the present invention for solving the above problems is to omit the drain port and the drain plug, and to simply form a drain hole, such as a hose or clamp that is connected to the outlet pipe, and to easily cool the water inside the radiator to the outside. The present invention also provides a radiator that reduces manufacturing costs by reducing the number of parts and manufacturing process by preventing leakage and leakage.

The present invention for achieving the above object is provided with the inlet and outlet pipes coupled to the inlet and outlet side hose and clamp to inlet / outlet the coolant, and also the upper and lower headers having a passage therein spaced apart from each other side by side And a tank 31, a plurality of tubes 33 installed in communication with the upper and lower header tanks 31, and heat dissipation fins 34 interposed between the tubes 33. In the radiator provided with a drain hole in the outlet pipe for discharging the cooling water to the outside, a hose drain hole is formed in the outlet hose is characterized in that the cooling water is discharged in accordance with whether or not the drain hole .

In addition, the inlet and outlet pipes coupled to the inlet and outlet side hoses and clamps to inlet / discharge the coolant, and the upper and lower header tanks 31 and the upper and lower header tanks 31 having a passage therein spaced in parallel to each other, and the upper , And a plurality of tubes 33 installed in communication with the lower header tank 31 and heat dissipation fins 34 interposed between the tubes 33 to discharge the internal cooling water to the outside. In the radiator provided with a drain hole in the outlet pipe, a stopper having a constant elasticity is inserted into the drain hole to prevent leakage.

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

The same parts as in the prior art are denoted by the same reference numerals, and repeated description thereof will be omitted.
