Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
The invention discloses a kind of booster auxiliary coolant system, tee pipe coupling 1, check valve 2, electric water pump 3 and
Respective line 4 forms, and check valve 2 and electric water pump 3 be arranged in parallel, the output end of the output end of check valve 2 and electric water pump 3 it
Between be provided with tee pipe coupling 1.Further, electric water pump of the invention is connect using tee pipe coupling with check valve or will
Check valve is integrated in tee pipe coupling, facilitates arrangement of the cooling system in vehicle body.
When electric water pump 3 does not work, coolant liquid flows to booster by the impeller gap of bypass line 5 and electric water pump 3
6；After engine stop work, the starting of electric water pump 3 provides coolant liquid circulation power, since check valve 2 forbids the anti-of coolant liquid
To flowing, booster 6 is all passed through by the coolant liquid of electric water pump 3, the shutdown to guarantee booster 6 is cooling.
When engine operates, electric water pump 3 does not work, and booster 6 provides cooling by the mechanical water pump that crankshaft drives.At this time
Most coolant liquids are flowed through by bypass line 5, small part coolant liquid by the impeller clearance of electric water pump 3, electric water pump 3
It is showed only as a flow resistance in systems.Cooling system running signal is as shown in Figure 3.Check valve positive pressure is higher than reversed pressure
Power, in positive opening state, resistance is lower.On the one hand, the check valve with electric water pump 3 of open state is in parallel, reduces increasing
System resistance before depressor 6 is conducive to guarantee to enter turbocharger bypass flow；On the other hand, the check valve of open state is to electric water
Pump 3 forms bypass and is shorted, and most water flows enter booster 6 by the lower check valve branch of resistance, pass through auxiliary on a small quantity
Electric water pump branch follows operating wasted work by water flow driving to reduce auxiliary electric water pump vane.
When engine stop operates, electric water pump 3 starts under the control of Engine ECU.Check valve buffer brake is higher than
Positive pressure is in reversed closed state, prevents the generation of reverse reflux, guarantees that the water outlet of electric water pump 3 fully enters booster
Branch.Since check valve 2 forbids the reverse flow of coolant liquid, booster 6 is all passed through by the coolant liquid of electric water pump 3, with
Guarantee that the shutdown of booster 6 is cooling, as shown in Figure 4.
The above is only a specific embodiment of the invention, but scope of protection of the present invention is not limited thereto, any to be familiar with
Within the technical scope disclosed by the invention, any changes or substitutions that can be easily thought of by those skilled in the art, should all cover
Within protection scope of the present invention.Therefore, protection scope of the present invention should be with protection scope defined by claims
It is quasi-.
