Dual cooling system of single-cylinder diesel engine set

Abstract

The invention discloses a dual cooling system for a single-cylinder diesel unit, which includes a dual cooling system for a diesel engine, including an air-cooled cylinder liner, a water-cooled surrounding pipe and a water tank cooling system. A water-cooling surround pipe is arranged between two adjacent air-cooled heat dissipation fins; the water tank of the diesel engine is connected to the water tank cooling system, and the water tank cooling system includes a blower. A driven pulley is installed on the external wheel shaft, and the driven pulley is connected to the flywheel pulley on the flywheel of the diesel engine through a belt, and the air outlet of the blower is connected to the air-cooled coil pipe arranged in the water tank of the diesel engine through a pipeline; the present invention combines water cooling on the basis of air cooling. Cooling, high efficiency, and equipped with a water tank cooling system, driven by the power of the diesel engine itself to cool down the diesel engine water tank, avoiding excessive water temperature in the diesel engine water tank, and improving water cooling efficiency, it is worthy of vigorous promotion.

Description

technical field [0001] The invention relates to the technical field of diesel engines, in particular to a dual cooling system for a single-cylinder diesel unit. Background technique [0002] Diesel engines have high thermal efficiency, good economy, and easy starting. They are used in working environments that require greater power. The existing single-cylinder diesel engines use flywheel fans and wind guides to control the cylinder liners with heat sinks, cylinder heads and aluminum alloys. The alloy body is forced air-cooled to reduce the working temperature of the cylinder liner, cylinder head and the temperature of the whole machine. The cooling efficiency of this air-cooled heat dissipation method close to the simple flywheel fan is low. The high temperature of the diesel engine has a direct impact on the output power, operation reliability and service life of the diesel engine. In severe cases, the diesel engine will burn oil or bite. Bearing bush and other vicious ac...

Problems solved by technology

The cooling efficiency of this air-cooled heat dissipation method close to the simple flywheel fan is low. The high temperature of the diesel engine has a direct impact on the output power, operation reliability and service life of the diesel engine. In severe cases, the diesel engine will burn oil or bite. Bearing bush and other vicious accidents, so it is necessary to design a cooling system that can improve the heat dissipation of the diesel engine
