However, the blower-type cooling fan 5 described above has a problem in that airflow efficiency is relatively lower than that of the suction-type cooling fan because the blower type 5 must blow external air and blow air toward the radiator assembly 4 due to the characteristics of heavy equipment. (5) The noise generated during operation caused the operator to work in a harsh environment due to various noises emitted from the equipment.

In addition, when the above-mentioned cooling fan 5 is driven, the hot air passing through the engine compartment 2 is blown directly to the radiator assembly 4 side, thereby lowering the cooling efficiency. Due to this, as the cooling fan 5 is rotated at high speed in order to increase the cooling efficiency, the power loss of the engine 1 is increased, and due to the high speed rotation of the cooling fan 5 described above, it is radiated from the equipment as a whole. The driver had a problem with noise.

Accordingly, an object of the present invention is to separate the heavy equipment cooling chamber such as a wheel loader from the engine compartment independently to prevent the hot air passing through the engine chamber directly to the radiator assembly to improve the cooling efficiency of the cooling device. It is to provide a parallel cooling system for heavy equipment to enable.

Another object of the present invention is to reduce the noise emitted when driving the equipment by lowering the rotational speed of the cooling fan due to the increase in the cooling efficiency of the cooling device, thereby providing a parallel working cooling for heavy equipment To provide a device.

Another object of the present invention is to provide a parallel cooling device for heavy equipment to maximize the cooling efficiency by applying a cooling fan therebetween to have an air flow having air flow characteristics suitable for the radiator and the oil cooler.

Another object of the present invention is to prevent the occurrence of thermal lamination due to stagnation of air inside the engine compartment due to the thrust of the air passing through the radiator assembly of the cooling chamber to prevent damage to various electrical appliances mounted inside the engine compartment. It provides a parallel cooling system for heavy equipment that extends the lifespan and increases cooling efficiency by joining fresh air from outside through the radiator assembly and then cooling the oil cooler.

A cooling room 24 is formed which is mounted and separated from the engine chamber 12 described above.

The radiator assembly 13 described above is mounted inwardly of the cooling chamber 24 to face the inlet grill 16 so that external air sucked in when the cooling fan 15 is driven is passed. An oil cooler 14 blows the air sucked in the aforementioned cooling fan 15 into the oil cooler 14 described above and then faces the outlet grill 17 so as to be discharged to the outside. It is mounted inside one cooling chamber 24.

The above-mentioned cooling chamber 24 is sucked into the first cooling chamber 18 and the above-mentioned cooling chamber 24 which suck the external air through the above-mentioned radiator assembly 13 when driving the above-mentioned cooling fan 15. The air is blown to the above-described oil cooler 14 and divided into a second cooling chamber 19 for discharging.

When the above-mentioned cooling fan 15 is driven at a predetermined position of the diaphragm 21 which partitions the engine chamber 12 and the cooling chamber 24 described above, the air thrust passing through the first cooling chamber 18 described above is explained. An engine compartment air vent 22 is formed inside the engine compartment 12 to prevent thermal lamination due to air congestion, and the air passing through the above-described radiator assembly 13 at a predetermined position of the second cooling chamber 19 is formed. The cooling chamber air vent 23 is formed to join the fresh outside air to increase the cooling efficiency of the oil cooler 14 described above.
