Description

Integrated radiator {INTEGRATED RADIATOR}

The present invention relates to an integrated radiator, and in more detail, the inverter cooling heat exchange medium or oil cooler cooling heat exchange medium is circulated in the upper and lower regions of the radiator so as to heat exchange the engine cooling heat exchange medium, which is the original function of the radiator, and at the same time the inverter. And it is possible to miniaturize by the heat exchange for the cooling of the oil cooler, and relates to an integrated radiator that can increase the 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, internal combustion engines always generate a very large amount of heat in the process of burning high-temperature, high-pressure gas. 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 efficiently cool the inverter, 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. have.

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.

On the other hand, the oil cooler (Oil Cooler) is provided in the automatic transmission vehicle is a device for cooling the engine oil of the torque converter or power transmission system. Since the temperature of the automatic transmission oil communicating with the inside of the oil cooler is higher than the temperature of the radiator, heat is exchanged by using the engine coolant of the radiator and cooled.
