Abstract
The utility model relates to a kind of marine diesel engine water-cooling exhaust pipe, comprises housing and interts the gas exhaust duct that is arranged in housing, and gas exhaust duct stretches out the outside of housing as one end of smoke exhaust port; Chamber between described gas exhaust duct and housing forms cooling water channel, housing is provided with the water intake and water outlet that are communicated with cooling water channel, after this water-cooling exhaust pipe, the temperature of smoke exhaust port can drop to about 80 degree, improve the environment of engine environment greatly, time particularly cabin is less, obvious improvement result is played to the temperature of surrounding aboard ship.
Description
Technical field
The utility model relates to a kind of cooling unit of diesel engine, particularly relates to a kind of marine diesel engine water-cooling exhaust pipe.
Background technique
Because marine diesel engine is in the process of work, the temperature of its engine smoke discharging mouth is often very high, usually about 400 degree are reached, thus cause engine environment ambient temperature too high, have a strong impact on the working stability of motor and the working life of engine components, particularly when cabin on ship is less, this drawback is more obvious, also can cause certain potential safety hazard simultaneously.
Model utility content
For above deficiency, the utility model provides a kind of marine diesel engine water-cooling exhaust pipe, effectively reduce the temperature of engine smoke discharging mouth, and structure is simple.
To achieve these goals, the technical solution adopted in the utility model is: a kind of marine diesel engine water-cooling exhaust pipe, comprises housing and interts the gas exhaust duct that is arranged in housing, and described gas exhaust duct stretches out the outside of housing as one end of smoke exhaust port; Chamber between described gas exhaust duct and housing forms cooling water channel, and described housing is provided with the water intake and water outlet that are communicated with cooling water channel.
Preferably, described housing is provided with at least one motor and enters mouth, and accordingly, described gas exhaust duct is provided with at least one smoke inlet flue be connected with gas exhaust duct for described motor being entered mouth vertically.
Preferably, in the cooling water channel of described smoke inlet flue between described gas exhaust duct and housing.
Preferably, described housing is provided with at least one motor and enters mouth, and accordingly, described gas exhaust duct is provided with at least one smoke inlet flue vertically.
Preferably, described housing, gas exhaust duct and smoke inlet flue are integrated casting.
The beneficial effects of the utility model:
The utility model structure is simple, novel, effectively utilize the circulating water of motor, the design of Water-cooling circulating pipeline is added between the housing and gas exhaust duct of motor, gas exhaust duct is made to be positioned at cooling water channel, enter the cooling water channel in this outlet pipe when circulating water of engine after, timely gas exhaust duct can be cooled, thus effectively reduce the temperature of engine smoke discharging mouth.The temperature of usual engine smoke discharging mouth is at about 400 degree, after this water-cooling exhaust pipe, temperature can drop to about 80 degree, improves the environment of engine environment greatly, time particularly cabin is less aboard ship, obvious improvement result is played to the temperature of surrounding, for the operation that engine high-efficiency is stable provides abundant guarantee, effectively extend the working life of engine components, simultaneously, effectively stop potential safety hazard, optimize working environment.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, referring to figs. 1 through Fig. 4, marine diesel engine water-cooling exhaust pipe of the present utility model, it comprises housing 1, gas exhaust duct 2 and cooling water channel 3, and housing 1, gas exhaust duct 2 and smoke inlet flue 21 are integrated casting.
The inside of housing 1 is the chamber of hollow, and gas exhaust duct 2 is interspersed to be arranged in housing 1.
Gas exhaust duct 2 is arranged along the length direction of housing 1, and the left end of gas exhaust duct 2 is closed and is positioned at the chamber of housing 1, and the right-hand member of gas exhaust duct 2 is that opening arranges and stretches out the outside of housing 1, thus forms smoke exhaust port 23, for getting rid of flue gas; Smoke inlet flue 21 is arranged on gas exhaust duct 2, and arrange several along the axis of gas exhaust duct 2, each smoke inlet flue 21 extends on housing 1 along the radial direction of gas exhaust duct 2, smoke inlet flue 21 defines into mouth 22 on housing 1, for entering in gas exhaust duct 2 by the cigarette that motor is discharged, in housing 1, multiple gas exhaust duct 2 also can be set.
Cooling water channel 3 is formed by the chamber between gas exhaust duct 2 and housing 1, and housing 1 is provided with the water intake 31 and water outlet 32 that are communicated with cooling water channel 3.
Working procedure of the present utility model is: when after engine operation, the temperature of motor smoke outlet flue 22 rises rapidly, simultaneously, circulating water of engine is by entering the cooling water channel of this water-cooling exhaust pipe at the water intake of housing 1, utilize circulating water of engine that the gas exhaust duct 2 in housing 1 is cooled timely and effectively, and then effectively reducing the temperature of engine smoke discharging mouth 23, the circulating water then absorbing heat is discharged from water outlet 32.
The foregoing is only better embodiment of the present utility model, the utility model is not limited to above-mentioned mode of execution, the structural modification that local is small may be there is in implementation process, if do not depart from spirit and scope of the present utility model to various change of the present utility model or modification, and belonging within claim of the present utility model and equivalent technologies scope, then the utility model is also intended to comprise these change and modification.
