RADIATOR EQUIPPED WITH INVERTER COOLING PART

[0001] The present invention relates to an inverter-cooled radiator, and more particularly, to a radiator for cooling an inverter, in which a heat exchange medium for cooling an inverter is circulated on the upper and lower sides of a radiator to heat exchange the heat exchanging medium for cooling the engine, To an inverter cooling integrated radiator which can be miniaturized and can increase heat exchange efficiency.

In recent years, interest in the environment and energy has been increasing worldwide in the automobile industry, and studies for improving fuel efficiency have been made. Research and development for lightening, miniaturization and high performance are continuously carried out in order to satisfy the needs of various consumers.

Meanwhile, the radiator is a component included in the category of the heat exchanger, and the radiator is a structure for preventing the temperature of the engine from rising to a certain temperature or higher.

Generally, the internal combustion engine always generates a very large amount of heat in the process of burning high temperature and high pressure gas, and various components including the cylinder and the piston are damaged due to overheating unless the heat is properly cooled.

Accordingly, a jacket for containing cooling water around the cylinder is provided, and the cooling water in the jacket is circulated so that the cooling water absorbs heat generated from the engine to cool the engine.

That is, the radiator circulates the inside of the engine, while the high-temperature cooling water that absorbs the heat generated by the combustion is circulated by the water pump, thereby releasing heat to the outside, thereby preventing the engine from overheating and maintaining the optimum operating condition Heat exchanger.

Meanwhile, the inverter is a driving motor for driving a compressor for compressing a refrigerant supplied to the evaporator, or a device for shifting the main motor for driving the electric vehicle.

The inverter is mainly made of a semiconductor material. When heat is generated in the switching operation for control, and the inverter is not properly cooled, the inverter affects the semiconductor element by the heat, and the operation of the driving motor or the main power motor Abnormalities may occur.

Conventionally, there has been proposed an air-cooling system in which a heat-radiating plate is attached to one side of an inverter to cool the inverter, air is blown through the cooling fan, and a water-cooling system in which cooling water is circulated by cooling water as in the case of the radiator.

However, the inverter cooling apparatus of the air-cooling type is difficult to efficiently cool the inverter, and in order to sufficiently cool the inverter of the high temperature, the size of the heat sink must be increased, and the blowing capacity of the cooling fan is increased to increase energy consumption .

In addition, since the water cooling type inverter cooling apparatus has a separate circulation line through which cooling water is circulated and a separate heat exchanger for lowering the temperature of the cooling water, there arises a problem that it interferes with downsizing of an automobile.

That is, in the dual heat exchange system, the engine cooling water is circulated to one side of the single radiator tank and the tube, and the inverter cooling water is circulated to the other side, so that the inverter can be cooled in a conventional radiator configuration without a separate heat exchanger for the inverter And the two heat exchange areas are integrally formed.

However, in the dual heat exchange system, the second heat exchange region for cooling the inverter is formed on one side of the radiator, and the first heat exchange region is formed to be much wider than the second heat exchange region to increase the cooling efficiency of the high- In particular, when the second heat exchange area (inverter cooling water flow area) is provided on the lower side of the vehicle, the amount of air passing through the second heat exchange area due to accumulation of external foreign substances and pin damage There is a problem that the inverter can not be cooled properly.
