Background technique
In order to reduce the operating temperature of motor; Through cooling system motor is cooled off; General cooling system is to utilize cooling liquid to take the heat of motor to radiator to dispel the heat; Reduce through the coolant temperature behind the radiator heat-dissipation, get back to motor heating place then and blow heat once more, so move in circles.And thermoregulator is one of important components in cooling system, and its function is through the induction coolant temperature, and the large and small circulation of control engine coolant is worked under the optimal state of being everlasting to guarantee internal-combustion engine.When coolant temperature when setting value is following, thermoregulator will lead to the pathway closure (being that major cycle is closed) of radiator, cooling liquid turns back to motor through short circle.When coolant temperature was elevated to the temperature value of setting, the path that thermoregulator will lead to radiator was opened, and cooling liquid is promptly returned behind radiator heat-dissipation with the major cycle return engine, thereby guaranteed the motor proper functioning.
Existing motor thermoregulator generally all is the mechanical type thermoregulator that adopts a kind of olefin structure, and the working principle of this thermoregulator is melted the characteristic that expands based on paraffin and promoted main valve.When engine water temperature was low, the main valve of thermoregulator was closed, and engine coolant is not walked major cycle; When engine water temperature was high, paraffin melted in thermoregulator wax bag, and the push rod that promotes in it moves, and drove the thermoregulator main valve and opened, and engine coolant is walked major cycle.The work of this kind paraffin thermoregulator all relies on the temperature of engine coolant to control fully; Can not regulate the opening degree of thermoregulator main valve according to the actual operating mode of motor; Also just can not realize accurately controlling the water temperature of motor, be unfavorable for the reduction of engine consumption and discharging.
Summary of the invention
The purpose of the utility model is to provide a kind of car engine electronic thermoregulator, can be according to the real time temperature state of motor, and the main valve of precisely controlling thermoregulator opens and closes.
The described a kind of car engine electronic thermoregulator of the utility model; Comprise thermoregulator lid, with thermoregulator cover cooperate be positioned at the main valve on the major cycle water route, the wax bag that is fixedly connected with main valve, be provided with water intake and short circle water outlet in the described thermoregulator portion of covering; Below described main valve, be provided with spring and support, this support is fixedly connected with the thermoregulator lid, and described spring lower end is fixed on the support, and main valve is withstood to valve closing direction in the upper end; In the thermoregulator lid, be provided with the push rod of band heating element, the upper end of the push rod of this band heating element is connected fixing with the thermoregulator lid, and insert in the wax bag lower end; The push rod of described band heating element is electrically connected with the ECU of automobile.
Cover at described thermoregulator and to be provided with the plug that is electrically connected with ECU, this plug is electrically connected with the push rod of being with heating element through lead; On main valve, be provided with seal rubber sleeve; Push rod at the band heating element is provided with seal ring at the fixed position that is connected with the thermoregulator lid.
The beneficial effect of the utility model is: on the function basis of existing thermoregulator, be provided with heating element, this heating element is controlled by vehicle-mounted ECU.ECU then comes the temperature conditions of real-time monitoring engine through each temperature transducer in the motor, adjust the heating-up temperature of heating element, the degrees of expansion of control wax bag, thus reached active, precisely control for the thermoregulator main valve.On the other hand, when heating element can't be worked, the cooling liquid that flows through in the thermoregulator lid also can make the wax bag expand, and realizes opening the function of main valve.

Embodiment
Engaging accompanying drawing and embodiment below does further to set forth in detail to the utility model:
Like Fig. 1, Fig. 2, shown in Figure 3; A kind of car engine electronic thermoregulator; Comprise thermoregulator lid 1, with the cooperation of thermoregulator lid be positioned at the main valve 3 on the major cycle water route, the wax bag 5 that is connected with the main valve soldering, cover 1 top at described thermoregulator and be provided with water intake and short circle water outlet; Below described main valve, be provided with spring 4 and support 6, this support 6 snaps onto on the thermoregulator lid 1, and described spring 4 lower ends are fixed on the support 6, and main valve 3 is withstood to valve closing direction in the upper end; In thermoregulator lid 1, be provided with the push rod 7 of band heating element, the upper end of the push rod 7 of this band heating element is connected fixing with thermoregulator lid 1, and insert in the wax bag 5 lower end; The push rod 7 of described band heating element is electrically connected with the ECU of automobile.Described thermoregulator lid 1 is provided with the plug 8 that is electrically connected with ECU, and this plug 8 is electrically connected through the push rod 7 of lead 2 with the band heating element; On main valve 3, be provided with seal rubber sleeve 9; Push rod 7 at the band heating element is provided with seal ring 11 at the fixed position that is connected with thermoregulator lid 1.
As shown in Figure 4; When lower or motor needs higher temperature when engine water temperature; The ECU system does not heat the push rod 7 of band heating element through plug 8; The wax bag 5 that is connected with the push rod 7 of band heating element can not expand, Gu main valve 3 is closed major cycle passage complete closed under the effect of spring 4.
As shown in Figure 5, when engine water temperature is higher when needing cooling or motor to need lower temperature, the ECU system makes push rod 7 heating of band heating element through plug 8, and the paraffin expanded by heating in the wax bag 5 drives main valve 3 and moves down, and then major cycle is opened.The ECU system is with the degree of heat of the push rod 7 of heating element according to motor real-world operation operating mode, engine water temperature, ambient temperature through judging control again, thus the opening clearance of adjustment main valve 3.In this way, can control the opening degree of main valve 3, motor major cycle water route flow is controlled in good time, thereby realize active, precisely control engine coolant temperature according to the actual requirement of motor.On the other hand, when the push rod 7 of band heating element can't be worked under ECU thrashing or other situation, the high temperature coolant that flows through in the thermoregulator lid also can make the wax bag expand, and realizes opening the function of main valve.
As shown in Figure 6; Described ECU gathers the foundation that the temperature of cooling water is judged the most according to the temperature transducer at the temperature transducer at motor water outlet place and cooling flange water outlet place; After ECU carries out analysis and judgement, export control signal again the device that adjusts the temperature electronically is controlled.
As shown in Figure 7; ECU sets the target temperature value of different phase according to the engine operation situation; When the coolant temperature that receives as ECU is higher than desired value; The ECU control device that adjusts the temperature electronically is opened valve, when the coolant temperature that receives as ECU is lower than desired value, and the ECU control device throttle down that adjusts the temperature electronically.
