In addition, another object of the present invention is to manufacture the shape of the ECU cradle in the shape of a quadrilateral, the engine control unit of the agricultural work vehicle to prevent the failure by preventing the heat of the radiator directly transmitted to the engine control unit directly to prevent the failure To provide a layout structure.

An object of the present invention described above is an agricultural work vehicle in which an engine is mounted at a rear side of an engine room, and an air cleaner, a radiator, and a cooling fan are sequentially installed in a front space in which the engine is mounted.

The cooling fan shroud is installed between the radiator and the cooling fan for guiding the flow of the heat exchange fluid, and an ECU cradle is formed on the cooling fan shroud, and the engine control unit is mounted on the ECU cradle. It can be achieved through the engine control unit arrangement of the working vehicle.

Here, the cooling fan shroud is manufactured in the form of a partition wall fixedly installed on the engine floor, the cooling fan is installed through the center of the cooling fan, the heat exchange fluid flow around the radiator is extended to the conical shape of the cooling fan to the cooling fan To be concentrated in the lateral direction, the upper portion is characterized in that the ECU mounting base on which the engine control unit is mounted.

In addition, the ECU cradle may be manufactured in a quadrangular enclosure shape, and an air supply pipe through hole to which an air supply pipe connected to an air cleaner is fixed may be formed at one side of the upper left and right sides where the ECU cradle is formed, and the cooling fan shroud Cooling water pipes through which the cooling water pipes are fixed at both ends of the upper left and right sides may be formed.

According to the present invention, the engine control unit may be installed between the radiator upper portion and the bonnet, thereby minimizing the risk of getting wet or exposed to water, thereby solving the electric failure problem.

In addition, the present invention is to be installed on the top of the cooling fan shroud ECU, it is possible to easily secure the installation space of the engine control unit without significantly modifying the existing engine room structure, the installation structure has a solid effect.

In addition, the present invention has the effect of preventing the failure by blocking the heat of the radiator directly transmitted to the engine control unit by manufacturing the shape of the ECU cradle into a quadrangular enclosure shape.

1 is a view showing the engine room in plan view to explain the engine control unit arrangement of the agricultural work vehicle according to the present invention.
Figure 2 is a front view of the engine room to explain the engine control unit arrangement of the agricultural work vehicle according to the invention.
Figure 3 is a perspective view of the inside of the engine room from the front to explain the engine control unit arrangement of the agricultural work vehicle according to the invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show the internal structure of the engine room 100 of the agricultural work vehicle of the present invention. As shown in the figure, the agricultural work vehicle of the present invention has an engine 110 mounted on the rear side of the engine room 100.

In addition, the engine room 100 is installed with various accessories for driving the vehicle, including the engine 110, in the inner space of the bonnet 101 is closed. In particular, an air cleaner 140 for filtering combustion air supplied to the engine 110 is installed in the front space in which the engine 110 is mounted, and the filtered air is supplied to the rear end of the air cleaner 140. Air supply pipe 141 for transferring to the side is connected.

In addition, a radiator 120 is installed at the rear of the air cleaner 140 to heat-exchange coolant for cooling the engine 110 with the atmosphere.

At this time, the radiator 120 receives the coolant heated from the engine 110 and heat-exchanges it with the atmosphere so that the cooling is performed, and recirculates the coolant that has undergone the heat exchange process to the engine 110 to heat the engine 110. It is cooling down.

Here, the radiator 120 forms inlets and outlets of the coolant on both left and right sides, respectively, and the inlets and outlets are connected to the engine 110 through the coolant pipes 151 and 152.

In addition, the cooling fan 130 is installed behind the radiator 120, that is, between the radiator 120 and the engine 110. The cooling fan 130 is an atmosphere that passes through the radiator 120, that is, heat exchange. By forcibly blowing the fluid to the engine 110 side, the circulation of the atmosphere around the radiator 120 is promoted to improve the cooling efficiency.

At this time, the cooling fan 130 is a state that is receiving the rotational power from the engine, the cooling fan shroud 131 is installed in the rotation radius, the cooling fan shroud 131 is a fluid around the radiator 120 It serves to guide the flow constantly in the cooling fan 130 side direction.

The cooling fan shroud 131 is manufactured in the form of a partition wall fixed to the bottom of the engine 110, the cooling fan 130 is installed through the center thereof, the shape of the cone around the cooling fan 130 It consists of a structure that forms an extension. The reason for having the cone-like expansion structure is to allow the air (heat exchange fluid) around the radiator 120 to be concentrated toward the center of the cooling fan 130.

At this time, the present invention is to install the engine control unit (ECU: Electronic Control Unit) (ECU) 200 using the upper space of the radiator 120, ECU mounting base 132 for mounting the engine control unit 200 is a cooling fan It is formed integrally on the shroud 131.

Here, the engine control unit 200 is an electronic control device that controls the state of the engine, automatic transmission, ABS, etc. by a computer, and serves to control all parts of the vehicle, including control, drive system, braking system, steering system, and the like. I'm doing it.

For example, for engine control, the water temperature sensor, oxygen sensor, etc. are calibrated by querying the ignition timing MAP (Manifold Absolute Pressure) value and the fuel injection MAP value that are set in advance according to the engine's intake air amount, intake pressure, opening degree, etc. The opening and closing rate is adjusted, thereby determining the fuel injection amount and the ignition timing.

Such an engine control unit 200 has a property that is vulnerable to moisture or moisture, it is preferable that the installation position is located above the radiator 120 and the cooling fan shroud 131, not the bottom of the engine 110. .

In this case, an ECU cradle 132 is mounted on the cooling fan shroud 131 to mount the engine control unit 200. The ECU cradle 132 may be formed in a quadrangular enclosure shape.

In addition, an air supply pipe through hole 133 to which an air supply pipe 141 connected to the air cleaner 140 is fixed is formed at one side of the upper left and right sides where the ECU mounting base 132 of the cooling fan shroud 131 is formed. In addition, coolant pipe through-holes 134 to which the coolant pipes 151 and 152 are fixed are formed at both left and right ends of the cooling fan shroud 131.

According to the present invention, the engine control unit 200 may be installed between the upper portion of the radiator 120 and the bonnet 101, thereby minimizing the risk of getting wet or exposed to water, thereby causing an electrical failure. Will be able to solve.

In addition, by installing the ECU mounting base 132 on the cooling fan shroud 131, it is possible to easily secure the installation space of the engine control unit 200 without significantly modifying the structure of the existing engine room 100, It will provide a solid installation structure.

In addition, the present invention by manufacturing the shape of the ECU cradle 132 in a quadrangular enclosure shape, thereby preventing heat from being transmitted directly to the engine control unit 200 by preventing heat from being lowered to the radiator 120.
