Dozer
A dozer including a cabin, the dozer includes: an engine room located in front of the cabin, where an engine is disposed; an exhaust gas after-treatment device for purifying exhaust gases emitted from the engine; a first cooling device located in front of the cabin and capable of cooling the exhaust gas after-treatment device; and a second cooling device spaced apart from the first cooling device, with the cabin midway therebetween, and capable of cooling the engine.
1 . A dozer including a cabin, the dozer comprising:
an engine room located in front of the cabin, where an engine is disposed;
an exhaust gas after-treatment device for purifying exhaust gases emitted from the engine;
a first cooling device located in front of the cabin and capable of cooling the exhaust gas after-treatment device; and
a second cooling device is disposed behind the cabin and capable of cooling the engine,
wherein
the exhaust gas after-treatment device is disposed above the engine in the engine room and disposed between the cabin and the first cooling device, and is configured to be cooled by the first cooling device, and
the first cooling device is located in the engine room.
2 . The dozer of claim 1 , further comprising a top cover covering at least one area above the engine room, with a top discharge opening formed therein through which air that has passed through the first cooling device is discharged.
3 . The dozer of claim 2 , wherein the top cover is configured to slope away from the cabin toward a distal end thereof.
4 . The dozer of claim 1 , further comprising a front grille portion formed with a front inlet opening for guiding outside air into the first cooling device.
5 . The dozer of claim 1 , further comprising a lateral body formed with a lateral intake opening for guiding outside air into the second cooling device.
6 . The dozer of claim 1 , wherein the first cooling device includes a charge-air cooler core.
7 . The dozer of claim 1 , wherein the second cooling device includes a cooling module for cooling a fluid therein through heat exchange with outside air.
8 . The dozer of claim 1 , further comprising a fuel tank located under the cabin, for supplying fuel to the engine.
9 . The dozer of claim 8 , further comprising an oil tank located under the cabin between the fuel tank and the engine, for storing a working fluid required for operation.
10 . The dozer of claim 9 , further comprising a main frame formed longitudinally in one direction, for supporting the engine, the fuel tank, and the oil tank.
11 . The dozer of claim 10 , wherein the first cooling device is situated farther away from the main frame than the engine.
12 . The dozer of claim 1 , further comprising a dividing member that divides the engine room and supports the exhaust gas after-treatment device so as to be located above the engine.
13 . The dozer of claim 1 , wherein the first cooling device is located in front of the exhaust gas after-treatment device and is inclined downward relative to the exhaust gas after-treatment device as the first cooling device extends toward a side relatively distant from the cabin.
14 . A dozer including a cabin, the dozer comprising:
an engine room located in front of the cabin, where an engine is disposed;
an exhaust gas after-treatment device located above the engine, for purifying exhaust gases emitted from the engine;
a first cooling device located in front of the exhaust gas after-treatment device in such a way as to slope away from the exhaust gas after-treatment device toward a distal end thereof, and capable of cooling the exhaust gas after-treatment device; and
a second cooling device located behind the cabin and capable of cooling the engine.
