Description

Combine {Combine}

The present invention relates to a combine, and more particularly to a combine configured to effectively collect and remove the air (Air) generated by the rise of the water temperature of the cooling water using a surge tank.

Combined diesel engines are usually installed in the combine, and the engine can easily overheat due to the nature of the work, which is mainly done in high load environments. In order to prevent overheating of the engine, a cooling system in which a high temperature coolant circulated inside the engine is cooled with air and then supplied to the engine is generally applied. Such cooling systems typically include radiators, water pumps, and the like.

For example, Japanese Laid-Open Patent Publication No. 2011-188815 discloses that a radiator is disposed on the gas side outside air introduction path so that cooling can be performed by wind caused by a suction force of a cooling fan suctioned toward the engine main body, and is disposed adjacent to the outside of the radiator. Disclosed is a configuration in which an oil cooler, an intercooler, and the like are arranged in a frame to be used.

In addition to the configuration disclosed in Japanese Patent Application Laid-Open No. 2011-188815, most of the cooling systems applied to combines are configured to simultaneously cool the radiator, the oil cooler, and the intercooler using the wind generated by the engine's cooling fan. do. That is, it is configured to cool the cooling water, the working fluid, and the intake air by the wind by the suction force of the cooling fan.

To this end, a radiator, an oil cooler, and an intercooler are formed in an assembly form in front of the fan shroud surrounding the cooling fan based on the flow of air generated by the cooling fan, and the outside air passes through the oil cooler and the intercooler. After the radiator is forcibly introduced into the engine room, the cooling fan is configured to provide efficient cooling performance.

In order to maintain the temperature of the cooling water below a certain temperature, a thermostat is installed on the cooling water introduction side of the radiator. The thermostat operates according to the water temperature of the cooling water to control the flow of the cooling water. When the cooling water is below the set temperature, the thermostat closes the flow path connected to the radiator side, and when the thermostat is above the set temperature, the flow path is opened to allow the radiator side flow.

That is, after the engine is driven, the inlet of the radiator is blocked by the thermostat until the temperature of the coolant reaches a certain temperature so that the engine can be preheated to an appropriate temperature within a short time. By allowing radiators to flow in, engine preheating and heat dissipation to the engine can be efficiently utilized.

On the other hand, the cooling water has a characteristic of repeating the expansion and contraction according to the temperature, and when the temperature rises, the evaporated portion remains in the cooling water in the form of bubbles, which acts as a major factor to reduce the engine cooling performance. That is, the main factor that lowers the cooling performance is air due to the increase in the cooling water temperature. Nevertheless, conventional cooling systems of combines are inadequate measures to prevent this.
