Description

Vehicle Reservoir Tank The present invention relates to a reservoir tank for a vehicle, and more specifically, to a reservoir tank for a vehicle that enables the reduction of weight and material costs by integrating a plurality of reservoir tanks, each containing coolant at a different temperature to satisfy the cooling performance of different parts. Generally, in vehicles equipped with internal combustion engines, the temperature of the heat generated when the engine heats up reaches a high temperature of approximately 1500°C or higher. If this heat is transferred directly to the cylinder head, piston, valve, etc., the temperature of these parts becomes excessively high, and due to thermal expansion or deterioration, deformation of the parts, breakdown of the lubricating film, and lack of lubricating oil occur. Furthermore, the combustion state deteriorates, leading to knocking or premature ignition, which reduces engine output, and in severe cases, causes engine overheating that results in inability to drive. In contrast, when the engine temperature is too low and the engine is in a supercooled state, the gasoline in the atomized mixture drawn into the cylinder is not sufficiently gasified, resulting in poor combustion and increased fuel consumption. Furthermore, unburned gasoline remains on the cylinder walls, causing the lubricating oil to become lean and affecting the operation and durability of the engine. Therefore, automobiles are equipped with a cooling system to maintain the optimal temperature for engine operation. Such cooling systems are divided into air-cooling, which cools the high-temperature engine by directing external air to the engine area, and water-cooling, which cools the high-temperature engine by circulating coolant to the combustion chamber. However, because air-cooling has lower cooling performance than water-cooling, automobiles primarily use water-cooling due to its superior cooling effect. Typically, a cooling system using coolant comprises an engine consisting of a cylinder head, coolant passages, and a combustion chamber; a radiator that cools water heated within the engine; a cooling fan that draws in air through the radiator to assist in the ventilation of the radiator; a water pump that supplies water cooled in the radiator back to the engine's coolant passages; and a reservoir tank provided in the coolant passages. These reservoir tanks store a constant amount of coolant to continuously discharge bubbles generated in the radiator and engine system that form in the coolant passages, and supply a constant amount of coolant via a water pump to prevent the occurrence of negative pressure in the coolant system. However, reservoir tanks must be provided separately, for example in the case of electric vehicles, because the type and temperature conditions of the coolant required for the cooling circuit to cool electrical components differ from the type and temperature conditions of the coolant required for the cooling circuit to cool the battery. Consequently, the increase in reservoir tanks for injecting and storing cooling water is causing problems such as increased weight, material costs, and investment costs.
