Engine temperature controller and temperature controlling method thereof

Abstract

The invention relates to an engine temperature controller and a temperature controlling method thereof. The engine temperature controller comprises a large circulation outlet pipe and a small circulation outlet pipe, wherein a temperature controller base is communicated with the large circulation outlet pipe and the small circulation outlet pipe; the upper part of the temperature controller base is provided with a temperature controller cover plate; the temperature controller cover plate is provided with a water inlet; an intermediate slide plate is arranged between the temperature controllercover plate and the temperature controller base; and the intermediate slide plate is provided with a water inlet, and can slip horizontally by the control of a motor. In the invention, the position of the intermediate slide plate is controlled by the motor, thereby realizing the accurate control of a valve.

Description

technical field [0001] The invention relates to an automobile engine thermostat and a temperature regulating method thereof. Background technique [0002] In the prior art, the thermostat commonly used on automobile engines is a paraffin structure thermostat, and the working principle of this thermostat is based on the property of paraffin wax melting and expansion. When the engine water temperature is low, the main valve of the thermostat is closed, the auxiliary valve is opened, and the engine cooling water goes through a small cycle without cooling. When the engine water temperature rises, the paraffin wax melts and expands in the temperature sensing body of the thermostat. During the expansion process, the push rod inside is pushed to move. When the push rod moves, the main valve of the thermostat is driven to open, and the auxiliary valve is closed. The engine cooling water goes through a large circulation to cool the engine, thereby reducing the engine temperature. T...

Problems solved by technology

The work of this kind of paraffin thermostat is completely controlled by the water temperature of the engine. The opening of the thermostat valve cannot be adjusted according to the actual working conditions of the engine, and the water temperature of the engine cannot be accurately controlled, which is not conducive to the reduction of engine fuel consumption and emissions.

Moreover, the manufacturing process of this paraffin thermostat is complicated, requiring high manufacturing precision and high production cost

[0003] Another thermostat commonly used on automobile engines is the electronic thermostat, which can work according to the water temperature and actual working conditions of the engine. Although this thermostat overcomes some shortcomings of the paraffin thermostat , but its structure is still based on the ordinary paraffin thermostat, and an electric heating element is added to the temperature sensing body of the thermostat to achieve

Therefore, this kind of electronic thermostat still opens the valve of the thermostat according to the characteristics of paraffin melting and expansion, it is difficult to realize precise control of the opening of the thermostat valve, and the electric heating element in the temperature sensitive body of the thermostat and the paraffin wax The sealing requirements between the two parts are relatively high, and the material and technology of the sealing related parts have high requirements, and the development cost and cost are relatively high.
