- Exemplary embodiments relate to an exhaust cooling apparatus capable of discharging exhaust gas from an engine of construction equipment to the atmosphere after cooling it down. More particularly, exemplary embodiments relate to an exhaust cooling apparatus for construction equipment, which sends exhaust gas to the atmosphere after cooling it down. In this disclosure, hot exhaust gas (about 1000° C.) emitted through an exhaust pipe from an engine of construction equipment such as excavator is mixed with air flowing out of an engine room and then cooled down in temperature.
- Exhaust gas discharged from an engine of heavy construction equipment such as excavator contains various kinds of harmful ingredients that may incur atmospheric pollution. For that reason, temperature of exhaust gas emitted from an engine is regularized on the level about 1000° C. on the legal standards (
Tier 4,Step 4, etc.). - Hot exhaust gas discharged to the atmosphere from an engine of construction equipment such as excavator, without removing or diminishing its toxicity, is easy to badly affect buildings or plant lives around the equipment, e.g., causing combustible matters to burn or plant lives to wither.
- As shown in
FIGS. 1 and 2 , a general crawler-type excavator is usually organized of a lower driving structure (or traveler) 1, an upper swing structure 2, anoperation cab 3, anengine room 4, aworking device 11, acounter weight 12 and anexhaust pipe 13. The upper swing structure 2 is mounted on thelower driving structure 1. The operation cab and theengine room 4 are disposed at the upper swing structure. Theworking device 11 is organized of a boom 6, an arm 8 and abucket 10. The boom 6 is movably coupled to the upper swing structure 2 and driven by a boom cylinder 5. The arm 8 is coupled to the boom 6 and driven by anarm cylinder 7. Thebucket 10 is coupled to the arm 8 and driven by a bucket cylinder 9. Thecounter weight 12 is installed at the rear of the upper swing structure and functions to balance the excavator at work. Theexhaust pipe 13 discharges hot exhaust gas to the atmosphere from the engine of the excavator. - In the meantime, referring to
FIG. 3 , a cooling system, which is usually employed in construction equipment such as the crawler-type excavator shown inFIGS. 1 and 3 , is generally organized of theengine room 4, theexhaust pipe 13, aradiator 20, anoil cooler 16, anoil cooler fan 17, aradiator fan 18 and ablower 19. Theengine room 4 accommodates anengine 14, theradiator fan 18, theoil cooler fan 17, ablower 19 and a hydraulic pump P, all of which generate noise at work, in a closed space by awall 4 a. Theexhaust pipe 13 discharges exhaust gas, which is emitted from theengine 14 through amuffler 15, to the atmosphere. Theradiator 20 cools down a coolant of theengine 14. Theoil cooler 16 cools down hydraulic fluid that returns to a hydraulic tank from an actuator (e.g., the boom cylinder 5). Theoil cooler fan 17 enables theoil cooler 16 to make a heat exchange by introducing external air into theengine room 4 through rotation of a hydraulic motor M. Theradiator fan 18 enables theradiator 20 to make a heat exchange by introducing external air into theengine room 4 through rotation of the hydraulic motor M. Theblower 19 discharges internal air to the outside from theengine room 4 by means of rotation of the hydraulic motor M. - In
FIG. 3 , thereference numeral 21 denotes a noise trap disposed at the side of the intake of theengine room 4, shielding and reducing noise that would be exposed to the outside of the construction equipment from theengine room 4. - With this organization, during work of the
engine 14, external air is introduced into theengine room 4 through rotation of theradiator fan 18 that is driven by the hydraulic motor M. Such external air taken into theengine room 4 is helpful to cooling down the coolant of theengine 4 by passing trough the radiator for heat exchange. - Meantime, the
oil cooler fan 17 rotated by the hydraulic motor M introduces external air into theengine room 4. The external air, which is taken into theengine room 4, passes through theoil cooler 16 for heat exchange and then cools down hydraulic fluid that returns to the hydraulic tank from the actuators. - The external air introduced into the
engine room 4 by rotations of theoil cooler fan 17 and theradiator fan 18 is discharged to the outside (i.e., to the atmosphere) by rotation of theblower 19, which is installed on the upper part of theengine room 4, after passing through theoil cooler 16 and theradiator 20. - In the cooling system aforementioned, the
exhaust pipe 13, which emits exhaust gas from theengine 14 by way of themuffler 15, is disposed toward the rear of theexcavator 13. Owing to such disposition of theexhaust pipe 13, exhaust gas of hot temperature could inadvertently harm or damage buildings or plant lives which are placed around the rear of the excavator. - Accordingly, the exemplary embodiments have been made to solve the above-mentioned problems occurring in the prior art while advantages achieved by the prior art are maintained intact.
- Exemplary embodiments of the present disclosure are directed to an exhaust cooling apparatus, for construction equipment, capable of preventing combustible matters, which are placed around the construction equipment such as excavator, from burning by hot exhaust gas. The final exhaust gas is discharged to the atmosphere after being cooled down, for which gas emitted from an engine through an exhaust pipe is mixed with air flowing out of an engine room through a blower.
- In an embodiment, there is provided an exhaust cooling apparatus for construction equipment having: a cooling fan taking external air into an engine room for heat exchange with an oil cooler and a radiator; and a blower flowing air from the engine room into the atmosphere. In the exhaust cooling apparatus, an outlet of an exhaust pipe for emitting exhaust gas from an engine may be fixedly disposed toward a discharge direction of the blower.
- In this embodiment, the discharge direction of the blower may be upwardly vertical to the ground.
- The above and other objects, features and advantages of the present disclosure will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:
-
FIG. 1 is a side view of a general crawler-type excavator; -
FIG. 2 is a schematic top view of the excavator without the working device shown inFIG. 1 ; -
FIG. 3 is a schematic configuration view of a general cooling system for construction equipment; -
FIG. 4 is a schematic configuration view illustrating an exhaust cooling apparatus for construction equipment according to an embodiment of the present disclosure; -
FIG. 5 is a top view illustrating an excavator equipped with the exhaust cooling apparatus shown inFIG. 4 ; -
FIG. 6 is a schematic view illustrating an operative feature of the exhaust cooling apparatus shown inFIG. 4 ; and -
FIG. 7 illustrates an operative condition of the exhaust cooling apparatus, according to exemplary embodiments of the present disclosure, in construction equipment. - Hereinafter, exemplary embodiments of the present disclosure will be described in conjunction with the accompanying drawings. The matters defined in the description, such as the detailed construction and elements, are nothing but specific details provided to assist those of ordinary skill in the art in a comprehensive understanding of the disclosure, and thus the present disclosure is not limited thereto. The same reference numerals are used for the same elements throughout the accompanying drawings.
- Referring to
FIGS. 4 through 7 , an exhaust cooling apparatus according to exemplary embodiments of the present disclosure may be applicable to construction equipment that has a cooling system including:cooling fans engine room 4 for heat exchange with aoil cooler 16 and aradiator 20; and ablower 19 discharging air from theengine room 4 into the atmosphere. The exhaust cooling apparatus is configured such that anoutlet 13 a of anexhaust pipe 13 for emitting exhaust gas from anengine 14 is fixed toward the discharge direction of theblower 19. - The discharge direction of the
blower 19 is upwardly vertical to the ground. - Except the
exhaust pipe 13 installed to cool down exhaust gas by mixing the exhaust gas, which is emitted from theengine 14 through theexhaust pipe 13, with air flowing out of theengine room 4 by theblower 19, the exhaust cooling apparatus shownFIGS. 4 through 7 is substantially similar to the cooling system shown inFIG. 3 . - Hereinafter, an operative condition of the exhaust cooling apparatus for construction equipment will be described with reference to
FIGS. 5 through 7 . - As illustrated in
FIGS. 5 through 7 , hot exhaust gas emitted from theengine 14 is discharged to the atmosphere by way of themuffler 15 and theexhaust pipe 13. External air taken into theengine room 4 by rotations of the cooling fans (i.e., anoil cooler fan 17 and a radiator fan 18) is heat-exchanged through theradiator 20 and theoil cooler 16. This heat-exchanged air is discharged to the atmosphere from theengine room 4 by rotation of theblower 19. - During this, as shown in
FIG. 5 , since theoutlet 13 a of theexhaust pipe 13 is fixedly disposed toward the discharge direction of theblower 19, the hot exhaust gas from theexhaust pipe 13 is mixed with air that flows out of theengine room 4 by theblower 19. - As a result, it is able to cool down the finally discharged exhaust gas in temperature by mixing the hot exhaust gas (about 1000° C.) with air (about 70° C. by heat exchange through the
radiator 20 and the oil cooler 16) that flows out of theengine room 4. - Summarily, hot exhaust gas emitted through the
exhaust pipe 13 is cooled down in temperature after mixing with air flowing out of theengine room 4 through theblower 19. Then, the cooled-down exhaust gas can be discharged to the atmosphere away from the ground as the discharge direction of theblower 19 is looking upward (seeFIGS. 5 and 7 ). - Therefore, even when there are buildings or combustible matters over the excavator, it is possible to prevent a fire because exhaust gas from the
engine 14 is discharged to the atmosphere in cool temperature. Moreover, even when the excavator is working under plant lives, it prevents the plant lives from withering due to hot and harmful exhaust gas. - As described above, the exhaust cooling apparatus for construction equipment according to this embodiment of the present disclosure is effective in preventing combustible matters from burning, or preventing plants from withering, due to hot exhaust gas around construction equipment such as excavator, by discharging the hot exhaust gas to the atmosphere after cooling it down by means of air flowing out of the engine room.
- Although exemplary embodiments of the present disclosure have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the disclosure as disclosed in the accompanying claims.
