Detailed Description

The following description will be made in conjunction with the specific embodiments of the present invention to further explain the cooling water path structure of the plug-in hybrid power system, so as to help the technicians in the field to understand the technical solution of the present invention more completely, accurately and deeply.

Example 1

As shown in fig. 2-3, the plug-in hybrid cooling water path structure of the embodiment includes an engine water jacket 10, a motor water jacket 20, and a radiator 30, where a liquid outlet end of the engine water jacket 10 is connected to a liquid inlet of the radiator 30 through a pipeline, a second thermostat 52 is disposed at a liquid inlet end of the engine water jacket 10, and a main liquid inlet end of the second thermostat 52 is connected to a liquid outlet of the radiator 30 through a pipeline. The liquid outlet of the radiator 30 is communicated with the main liquid inlet end of the first thermostat 51 through a pipeline, the liquid outlet end of the engine water jacket 10 is communicated with the auxiliary liquid inlet end of the first thermostat 51 through a pipeline, the liquid outlet end of the first thermostat 51 is connected with the liquid inlet end of the motor water jacket 20 through a pipeline, the liquid outlet end of the motor water jacket 20 is connected with the liquid return end of the engine water jacket 10 through a pipeline, and a water pump 60 is arranged at the liquid return end of the engine water jacket 10. The plug-in hybrid power cooling water path structure further comprises an auxiliary water tank 40, wherein the auxiliary water tank 40 is connected with a water inlet of the radiator 30 and a water inlet of the engine water jacket 10 through water pipes.

In the plug-in hybrid cooling water path structure of the present embodiment, the operating state of the first thermostat and the coolant circulation path are as follows:

a. when the temperature of the cooling liquid is lower, the second thermostat is closed, such as a warming-up stage. At this time, the first thermostat blocks the coolant flowing out of the radiator, feeds the coolant of the engine to the motor, and returns the coolant flowing out of the motor directly to the engine water jacket. In this way the optimum operating temperature can be reached quickly and the operating state of the first thermostat is shown in fig. 4.

b. The first thermostat is thus partially open due to the high engine coolant temperature. So that the high-temperature coolant from the engine and the low-temperature coolant from the radiator are mixed with each other. The coolant temperature is self-regulated in this "hybrid mode" in the coolant supply line to the motor to bring the motor to the optimum temperature range (about 80 c), the operating state of the first thermostat being shown in fig. 5.

c. This will occur if the coolant temperature in the radiator continues to rise, the first thermostat will be fully open, for example, when the second thermostat of the engine is open for a large cycle. The first thermostat closes the coolant line from the engine as the coolant temperature warms up. At this time, all the coolant from the radiator flows into the motor, and the first thermostat operates as shown in fig. 6.

For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
