Roundabout cooling and filtering type engine oil cooler

Abstract

Provided is a roundabout cooling and filtering type engine oil cooler, comprising an upper housing, a lower housing, a upper backflow guiding dike, a lower backflow guiding dike, and cooling fins. The upper housing and the lower housing are connected in a sealed manner to form a closed container. The top end of the upper housing is provided with an oil inlet and an oil outlet. The upper backflow guiding dike is arranged between the oil inlet and the oil outlet and is on the inner wall of the upper housing. The lower backflow guiding dike is arranged on the inner wall of the lower housing. The shape of the lower backflow guiding dike is the same with the shape of the upper backflow guiding dike, and the position of the lower backflow guiding dike is corresponding to the position of the upper backflow guiding dike. When the upper housing and the lower housing are closed, the top end face of the upper backflow guiding dike contacts the top end face of the lower backflow guiding dike. The cooling fins are uniformly arranged on the outer walls of the upper housing and the lower housing. The upper housing is arranged on the lower end of a diesel engine block, and the oil inlet of the upper housing is abutted against the oil outlet on the bottom surface of the engine block in a sealed manner. Using the oil cooler, temperature of machine oil can reduce by 14 to 30 DEG C, and machine oil cleanliness is ensured, and continuous operation of a good state and long service life of an engine are ensured.

Description

technical field [0001] The invention relates to a vertical single-cylinder air-cooled diesel engine, in particular to an engine oil cooler for a vertical single-cylinder air-cooled diesel engine. Background technique [0002] When the engine is working at high load, it will generate a lot of heat. In the actual use process, we will find that the oil temperature of the diesel engine will be very high under the condition of high speed and heavy load, sometimes even exceeding 130°C. If the engine oil of the diesel engine If the temperature is too high for a long time, the viscosity of the oil will decrease, the fluidity of the oil will increase, it will be difficult for the oil to form an oil film between the friction pairs, and the pressure of the oil will drop, resulting in poor lubrication of parts and accelerated wear. Hold the tiles, etc., so that the engine fails. Therefore, most of the heat generated by the engine is taken away by the engine cooling system circulation, ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a detour cooling filter type engine oil cooler, which can not only increase the oil storage capacity of the engine, effectively reduce the temperature of the engine oil, but also carry out two-stage filtration of the oil, so as to overcome the problem of engine oil in the prior art. The inventory is too small, the oil cleanliness is not high, and the oil temperature is too high to cause many problems
