Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described in detail.It should be appreciated that this place is retouched
The detailed description of the invention stated is merely to illustrate and explains the present invention, is not limited to the present invention.
As in figure 2 it is shown, the present invention provides the cooling system of a kind of vehicle, vehicle includes electromotor 10 and Retarder
20, wherein, cooling system includes the water inlet of radiator 30 and thermostat 40, the outlet of electromotor 10 and Retarder 20
Being connected, the outlet of Retarder 20 is connected with the water inlet of thermostat 40, the first outlet of thermostat 40 and radiator 30
Being connected, the second outlet of thermostat 40 is connected with the water pump 50 of electromotor 10.
As shown in fig. 1, pipeline 3 connects outlet and the water inlet of Retarder 20 of electromotor 10, and pipeline 1 connects
The outlet of Retarder 20 and the water inlet of thermostat 40, pipeline 4 connects the first outlet and radiator 30 of thermostat 40,
Pipeline 2 connects the second outlet of thermostat 40 and the water pump 50 of electromotor 10, and pipeline 5 connects radiator 30 and water pump 50.
Temperature when electromotor 10 normally works is usually 80 DEG C to 95 DEG C, when the temperature of coolant is less than 80 DEG C, and joint
First port closing of temperature device 40, the second outlet is opened.Coolant enters fluid power from the outlet of electromotor 10 through piping 3 and delays
The water inlet of speed device 20, coolant flows out from the outlet of Retarder 20 after Retarder 20.Subsequently, coolant
Enter pipeline 1, and flowed into thermostat 40 by pipeline 1, owing to the first port closing, second outlet of thermostat 40 are opened, therefore,
Enter the coolant of thermostat 40 from the second outlet flow ipe 2, and enter water pump 50 and complete a circulation.
When the temperature of coolant is higher than 80 DEG C, the first outlet of thermostat 40 is opened, the second port closing.Coolant from
The outlet of electromotor 10 enters the water inlet of Retarder 20 through piping 3, coolant after Retarder 20 from
The outlet of Retarder 20 flows out.Subsequently, coolant enters pipeline 1, and is flowed into thermostat 40 by pipeline 1, due to joint temperature
First port closing of device 40, the second outlet are opened, and therefore, the coolant entering thermostat 40 exports flow ipe 4 from first,
Then stream carries out radiating and cooling as in radiator 30, and the coolant after cooling enters pipeline 5, then flows into water pump 50 from pipeline 5
Complete a circulation.
When electromotor 10 works, Retarder 20 does not works.When Retarder 20 works, electromotor 10 does not works.
No matter coolant is circulated according to which kind of mode above-mentioned can cool down electromotor 10 and Retarder 20 simultaneously.
That is, electromotor 10 and Retarder 20 shares same set of cooling system, thus has saved the parts of cooling system, and reduces
Space shared by cooling system, the beneficially layout of cooling system.
Steam is easily produced, in order to prevent steam from hindering the circulation of coolant when coolant at high temperature circulates, it is preferable that
