Description

Tank for radiator {TANK FOR RADIATOR}

The present invention relates to a tank for a radiator, and more particularly, to a tank for a radiator configured to increase heat exchange performance by preventing drift of the coolant flow and improving the coolant fluidity.

In general, internal combustion engines generate a lot of heat during operation, which is conducted to cylinder headers, pistons, valves and the like. Excessively high temperature delivered to these parts not only causes the strength of the parts to decrease due to thermal expansion or deterioration, and shortens the engine life, but also worsens the combustion state, leading to knocking and premature ignition, thereby lowering the engine output. In addition, when the engine is incompletely cooled, the oil film on the inner circumference of the cylinder is broken, and the lubrication function is deteriorated. Also, the engine oil is deteriorated, which causes abnormal cylinder wear, and the piston is fused to the inner wall of the cylinder. .

In order to cool the engine, a car is usually equipped with a water-cooled cooling device, which is configured to circulate the coolant by a water pump in a water jacket provided in the cylinder block and the cylinder header to promote the cooling operation of the engine. Radiator, cooling fan and water temperature controller are provided.

On the other hand, the radiator is a device for circulating the cooling water heated in the engine to cool by heat dissipation, as shown in Figure 13, the upper header pipe 91, the lower header pipe 92, the upper and lower header pipe ( A plurality of tubes 93 connecting 91 and 92, corrugated heat dissipation fins 94 laminated between the tubes 93 to dissipate heat, and the tube 93 and fins 94 It includes both supports (95, 95) installed on the outermost side of the reinforcement. The upper header pipe 91 has a header 911 having a plurality of insertion holes (not shown) formed in a lengthwise direction along the bottom of the tube 93 so that the ends of the tubes 93 can be coupled to each other, and the header 911 having an upper opening. It is composed of a tank 912 coupled to the upper to form a flow path therein, and the lower header pipe 92 also includes a header (not shown) and a tank 922 formed like the upper header pipe. The tanks 912 of the upper header pipe 91 are provided with a filler neck 914 to which the cooling water inlet 913 and the radiator cap 915 are opened and closed, and the tank 922 of the lower header pipe 92. The cooling water discharge port 923 and the drain cock (not shown) are provided in this order.

In the conventional radiator configured as described above, when the coolant flows into the upper header pipe 91 through the coolant inlet 913, for example, the coolant flow cross-sectional area at each point is substantially the same along the length of the upper header pipe 91. Therefore, a large amount of coolant flows through the tubes 93 located near the coolant inlet 913 and the coolant flows through the tubes 93 near the supports 95 and 95 at a location far from the coolant inlet 913. Since a drift phenomenon in which the flow amount decreases occurs, there is a problem in that heat radiation of the cooling water is not evenly performed throughout the radiator.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a radiator tank that can increase the heat dissipation of the coolant by preventing the coolant flow from flowing and allowing the coolant to flow evenly throughout the radiator.

In order to achieve the above object, the present invention is coupled to the upper portion of the header 11 is inserted into the end of the tube (3) of the radiator to form a header pipe (1) of the radiator and a radiator with a coolant inlet 13 formed on one side In the tank for cooling, the ceiling 122 of the tank 12 is inclined downward or recessed toward the rear wall 123 so that the distance from the center of the cross section to the rear wall 123 is reduced, so that the coolant flow cross-sectional area is the coolant inlet 13 It is characterized in that it is made to increase while going to both support (5,5) side of the radiator.

 According to the tank for a radiator according to the present invention configured as described above, since the cross-sectional area of the coolant flow increases gradually from the region adjacent to the cooling water inlet side of the tank toward both support side regions of the radiator, compared to the conventional support area of both radiators Since a relatively large amount of coolant flows, the flow of the coolant is evenly distributed, thereby improving heat exchange efficiency.

Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings.

The upper tank 12 is provided with a coolant filler neck 14 and a coolant inlet 13 to which the radiator cap 15 is coupled, and a coolant outlet 23 and a drain cock (not shown) are installed in the lower tank 22. do. In addition, an oil cooling pipe (not shown) for cooling the transmission oil may be built in the lower tank 22.

The upper and lower header pipes 1 and 2 are connected to each other by inserting the upper and lower end tubes into the insertion holes corresponding to each other, and the upper and lower header pipes 1 and 2 are connected to each other. The flow paths communicate with each other, and the heat dissipation fins 4 are sequentially stacked between the tubes 3. In addition, side supports 5 are respectively installed at the outermost sides of the tubes 3 and the heat dissipation fins 4.

According to the first embodiment, the upper tank 12 is formed such that the coolant flow cross-sectional area gradually increases from the region adjacent to the cooling water inlet 13 toward the region of both supports 5 and 5 of the radiator.

The distance to the rear wall 123 of the upper tank 12 gradually decreases from the region of the cooling water inlet 13 side (see FIG. 3) to the region of the two support 5 side (see FIG. 4), thereby to the cooling water inlet 13 side. The cooling water flow cross-sectional area of both support 5 side regions becomes wider than the region adjacent to the side wall.

Preferably, the partition wall 121 has a quadrant or quadrant elliptical cross section (see FIGS. 3 and 4), and in this case, the center distance of the partition wall 121 from the region of the cooling water inlet 13 may be 5) It decreases toward the area. In addition, as shown in FIG. 5 (the cooling water inlet 13 side) and FIG. 6 (the support 5 side), the cross-sectional shape of the partition wall 121 may be diagonal, but is not limited thereto. Any partition wall 121 may be employed as long as the cross-sectional area of the coolant flow in both support 5 regions is wider than the region adjacent to the &quot;

According to the tank for a radiator according to the first embodiment configured as described above, both supports (5, 5) of the radiator from the region adjacent to the cooling water inlet 13 by the partition wall 121 installed in the upper tank 12 Since the cross-sectional area of the coolant flow increases toward the () side area, a relatively large amount of coolant flows to both the support (5, 5) side areas of the radiator, so that the flow rate of the coolant is evenly distributed, thereby improving heat exchange efficiency. .
