Abstract
The utility model relates to the technical field of an engine and specifically relates to a cabinet for a single-cylinder air-cooled diesel engine. The cabinet for the single-cylinder air-cooled diesel engine comprises a crank case, wherein a cylinder is arranged above the crank case; the crank case comprises a front wall, a lateral wall and a bottom part; a cavity for accommodating the crank case is formed by the front wall, the lateral wall and the bottom part; a radiating fin is arranged on an outer wall of the bottom part; a cross section of the radiating fin is in a wave form; a reinforcing rib is arranged on the outer wall of the lateral wall. The strength and the radiating property of the single-cylinder air-cooled diesel engine are enhanced by the cabinet provided by the utility model.
Description
Technical field
The utility model relates to a kind of technical field of engines, specifically relates to single-cylinder air-cooled diesel engine casing.
Background technique
The feature that single-cylinder air-cooled diesel engine is lightweight with it, volume is little, simple in structure, easy to maintenance, is subject to users' favor deeply.Yet, compare with water-cooled diesel engine seem especially " fragile ".Air-cooled diesel engine is that the strong air flow blowing out by impeller flows rapidly along radiating fin, thereby reduces organism temperature.And if by existing single-cylinder air-cooled expansion cylinder increasing power, just the radiating efficiency of the intensity of single-cylinder wind cooling diesel engine body and body is had higher requirement.
Model utility content
The purpose of this utility model is to provide a kind of single-cylinder air-cooled diesel engine casing that can increase casing intensity and heat dispersion.
The utility model is achieved through the following technical solutions: single-cylinder air-cooled diesel engine casing, comprise crankcase, crankcase top is provided with cylinder, crankcase comprises positive wall, sidewall and bottom, the cavity that holds bent axle is formed on positive wall, sidewall and bottom, wherein, bottom outer wall is provided with radiating fin, and the cross section of radiating fin is waveform; The outer wall of sidewall is provided with stiffening rib.
The beneficial effects of the utility model are: existing radiating fin cross section is regular rectangular mostly, the air-flow that impeller blows out flows along the surface of radiating fin, take away the heat that diesel engine produces, the cross section of radiating fin of the present utility model is waveform, so just increased the surface area that air contacts with radiating fin, make moving air can take away more heat, improved the radiating efficiency of radiating fin; It is in order to increase the intensity of diesel engine box body that stiffening rib is set on the outer wall of sidewall.
Further, the inwall of positive wall is provided with connection bump, in connection bump, be provided with ventilation flue, the intake grill of ventilation flue is positioned at positive wall outer wall, the exhaust outlet of ventilation flue is positioned at bottom outer wall, and connection bump is arranged on positive wall inwall and contacts with the high machine oil in diesel engine box body, impeller produce high velocity air by the ventilation flue in connection bump, air-flow is taken away the heat of ventilation flue inside, accelerates the heat radiation of diesel engine box body.
Accompanying drawing explanation
Fig. 1 is the perspective view in the utility model single-cylinder air-cooled diesel engine casing front;
Fig. 2 is the perspective view of the utility model single-cylinder air-cooled diesel engine box back surface.
Embodiment
Single-cylinder air-cooled diesel engine casing shown in 1,2 by reference to the accompanying drawings, comprise crankcase, described crankcase top is provided with cylinder 1, described crankcase comprises positive wall 7, sidewall 5 and bottom 6, positive wall 7, sidewall 5 form with bottom 6 cavity that holds bent axle, wherein, described bottom 6 outer walls are provided with radiating fin 3, and the cross section of described radiating fin 3 is waveform; The outer wall of sidewall 5 is provided with stiffening rib 2, and the inwall of positive wall 7 is provided with connection bump 8; Connect in protruding 8 and be provided with ventilation flue, the intake grill 4 of ventilation flue is positioned at positive wall outer wall, and the exhaust outlet of ventilation flue is positioned at bottom outer wall.
During single-cylinder air-cooled diesel engine running, the heat that body produces is transmitted to radiating fin 3 and ventilation flue through casing, in single-cylinder air-cooled diesel engine, impeller produces air-flow, airflow passes radiating fin 3 and ventilation flue, air-flow is taken away the temperature that heat has reduced body, on sidewall 5 outer walls, the intensity that stiffening rib 2 has been strengthened body is set simultaneously.In the time of cooling, strengthen cylinder block strength, guaranteed single-cylinder air-cooled diesel engine normal operation.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
