Method for controlling valve opening in thermostat by engine cooling water channel temperature and oil-water thermostat

Abstract

The invention relates to an oil-water temperature saver and a method for controlling the opening of a valve inside a temperature saver body by the temperature of an engine cooling water way. The engine cooling water way is provided with the oil-water temperature saver, the opening of the valve inside the temperature saver body is controlled by utilizing the temperature of the engine cooling water way to automatically adjust the oil flow capacity of an oil valve so as to control the rotating speed of a fan with a hydrodynamic coupler, thereby the purpose of automatically controlling the engine temperature of vehicles is achieved. Furthermore, the starting control temperature of the oil-water temperature saver is between 70 DEG C and 90 DEG C, the oil-water temperature saver comprises a temperature saver sleeve assembly and a temperature saver body, wherein screwed connections arranged on the temperature saver body and the temperature saver sleeve assembly are connected together through screw threads, and adjusting washers are arranged between the temperature saver body and the screwed connections; the oil-water temperature saver is arranged on an engine water way in a connecting way through screw threads, a temperature sensing body of the oil-water temperature saver is arranged in the engine water way, and the position of the temperature sensing body inside the engine water way is adjusted and fixed by a nut and a washer.

Description

technical field [0001] The invention relates to the technical field of the vehicle cooling system, specifically controls the opening of the valve in the thermostat according to the temperature of the engine water channel, thereby controlling the speed of the fan with the fluid coupling to automatically control the temperature of the vehicle engine method and device. Background technique [0002] Generally, vehicles are equipped with heat sources such as engines, and the engine temperature must be automatically controlled within a certain range. Therefore, a fan with a certain displacement must be designed for cooling, and a thermostat with high sensitivity that matches the fan and automatically controls the fan speed must be designed. Deutz's BF / L413 series exhaust gas thermostat for air-cooled diesel engines can only collect the temperature of the exhaust pipe, which is affected by the large temperature range of the exhaust pipe and has poor sensitivity. The water channel ...
