Inverter cooling integrated radiator {RADIATOR EQUIPPED WITH INVERTER COOLING PART}

The present invention relates to an inverter cooling integrated radiator, and more particularly, the heat exchange medium for inverter cooling is circulated on the upper side and the lower side of the radiator to heat exchange the engine heat exchange medium and at the same time, the heat exchange for the inverter cooling is made, integrally. The present invention relates to an inverter cooling integrated radiator capable of miniaturization and increasing heat exchange efficiency.

In recent years, as the interest in the environment and energy in the automobile industry is increasing, researches for improving fuel efficiency have been conducted, and research and development for light weight, miniaturization, and high functionalization have been steadily made to satisfy various consumer needs.

On the other hand, the radiator is a component included in the category of the heat exchanger, the radiator (radiator) is a configuration for preventing the temperature of the engine rises above a certain temperature.

In general, the internal combustion engine always generates a very large amount of heat in the process of burning a gas of high temperature and high pressure, and if the heat is not properly cooled, various components including the cylinder and the piston are damaged due to overheating.

Therefore, a jacket is provided around the cylinder to accommodate the cooling water, and the engine is cooled by absorbing heat generated from the engine by circulating the cooling water inside the jacket.

That is, the radiator circulates through the engine while absorbing the heat generated by the combustion, and the hot water is circulated by the water pump, thereby dissipating heat to the outside to prevent overheating of the engine and to maintain an optimal operating state. Heat exchanger.

On the other hand, the inverter (Inverter) is a device provided for the transmission of the drive motor for driving the compressor for compressing the refrigerant supplied to the evaporator or the main power motor for driving the electric vehicle.

The inverter is mainly made of a semiconductor material, the heat is generated during the switching operation for control, when the inverter is not properly cooled, the heat affects the semiconductor element to operate the drive motor or the main power motor Anomalies may occur.

Conventionally, in order to cool the inverter, a heat sink is attached to one side of the inverter, an air cooling method for blowing air to a cooling fan, and a water cooling method for cooling by circulating cooling water like the radiator has been proposed.

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

In addition, the water-cooling inverter cooling device has a problem that acts as a factor that hinders the miniaturization of the vehicle because a separate circulation line through which the coolant is circulated, and a separate heat exchanger for lowering the temperature of the coolant.

However, in the dual heat exchange system, a second heat exchange area for cooling the inverter is formed on one side of the radiator, and a first heat exchange area is formed to be much wider than the second heat exchange area to increase the cooling efficiency of the high temperature engine coolant. Therefore, the inverter cooling water cannot be sufficiently cooled, and in particular, when the second heat exchange zone (inverter coolant flow zone) is provided under the vehicle, the amount of air passing through the second heat exchange zone due to accumulation of external foreign matter and fin damage. There is a problem that the lower the inverter can not be properly cooled.
