Exhaust cooling apparatus for construction equipment

Abstract

An exhaust cooling apparatus for construction equipment, having a cooling fan taking external air into an engine room for heat exchange with a oil cooler and a radiator, and a blower flowing air out of the engine room to the atmosphere. In the apparatus, an outlet of an exhaust pipe for emitting exhaust gas from an engine is fixedly disposed toward a discharge direction of the blower. The discharge direction of the blower is upwardly vertical to the ground. The exhaust cooling apparatus is effective in preventing combustible matters from burning, or preventing plant lives 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 through air flowing out of the engine room.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based on and claims priority to Korean Patent Application No. 10-2008-0120229, filed on Dec. 1, 2008, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.FIELD OF THE DISCLOSURE[0002]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.BACKGROUND OF THE DISCLOSURE[0003]Exhaust gas discharged from an engine of heavy construction equipmen...

Problems solved by technology

Exhaust gas discharged from an engine of heavy construction equipment such as excavator contains various kinds of harmful ingredients that may incur atmospheric pollution.

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.

Owing to such disposition of the exhaust 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.
