System, electromotor self is with water pump and built-in thermostat, in whole cooling system, when engine water temperature is relatively low, joint temperature
Device cuts out, and now cooling water is without water tank, only circulates at engine interior, is commonly called as partial circulating；When engine water temperature reaches joint
When temperature opened by temperature device (thermostat is opened temperature and is generally 80-90 DEG C), now thermostat is opened, and cooling water is carried out by water tank
Cooling, be commonly called as systemic circulation, whole cooling system make with time electromotor can only be cooled down, change speed gear box and retarder can not obtain
To cooling.

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is this utility model partial circulating trend when engine water temperature is relatively low；
Fig. 3 is this utility model systemic circulation trend when engine water temperature is higher.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further:
One in-line power assembly cooling system as shown in Figure 1, including water tank 1, electromotor 2, retarder 3 and outer
Putting thermostat 4, the outlet of water tank 1 is connected with electromotor 2, and the outlet of electromotor 2 is connected with retarder 3, the outlet of retarder 3
Import with external thermostat 4 is connected, and the first outlet of external thermostat 4 is connected with electromotor 2, the second of external thermostat 4
Outlet is connected with the water inlet of water tank 1.
Further, electromotor 2 is integrated with water pump 21 and electromotor thermostat 22, and retarder 3 is integrated with retarder heat and hands over
Parallel operation 31, the outlet of water tank 1 is connected with water pump 21, and the outlet of water pump 21 is connected with electromotor thermostat 22, and electromotor saves
The outlet of temperature device 22 is connected with retarder heat exchanger 31, the outlet of retarder heat exchanger 31 and the import of external thermostat 4
Being connected, the first outlet of external thermostat 4 is connected with water pump 21, and electromotor thermostat 22 is normally open.
Further, the water inlet of water pump 21 is connected with expansion tank 5 simultaneously.
Further, the unlatching temperature of external thermostat 4 is 80 DEG C～90 DEG C.
Further, when external thermostat 4 is in open mode, the import of external thermostat 4 communicates with the second outlet, the
One outlet is closed；When external thermostat 4 is closed, the import of external thermostat 4 is connected with the first outlet,
Second outlet is closed.Namely when engine water temperature reaches the unlatching temperature 80 DEG C～90 DEG C of external thermostat,
External thermostat 4 is just opened.
Operation principle of the present utility model is as follows:
As in figure 2 it is shown, when engine water temperature is relatively low, external thermostat is closed, now the second outlet of external thermostat
Closing, the import of external thermostat and the first outlet communicate, and cooling water is without water tank, only at retarder heat exchanger, external
It is circulated between thermostat and electromotor, is commonly called as partial circulating；The concrete trend in its water route is: water pump → electromotor thermostat →
Retarder heat exchanger → external thermostat → water pump.
As it is shown on figure 3, when engine water temperature reach external thermostat open temperature time, external thermostat opens, now outside
Putting the first port closing of thermostat, the import of external thermostat communicates with the second outlet, cooling water by water tank, water tank,
Electromotor, it is circulated between retarder heat exchanger and external thermostat, is commonly called as systemic circulation；The concrete trend in its water route is:
Water tank → water pump → electromotor thermostat → retarder heat exchanger → external thermostat → water tank.
In sum, this utility model is by the connected mode of series connection, it would be desirable to the power assembly parts of water-cooled are connected to
