Description
Technical field
The present invention relates to a kind of structure based on NG electromotor passenger vehicle warm braw pipeline, belong to passenger vehicle heat dissipation pipeline technology neck
Territory.
Background technology
At present, rearmounted NG electromotor passenger vehicle all replaces independent heating apparatus with heater exhaust gas, to meet inside passenger vehicle
The thermal source supply of frost removal and radiator, makes passenger vehicle travel under safety, comfortable duty；But with heater exhaust gas
NG electromotor, vehicle is when running summer, and the current after heating equally can return to the water inlet steel pipe of electromotor, enters into and starts
In the great circulation system of machine self-radiating device, so that the heat-sinking capability of NG engine radiator declines, NG time serious, can be caused to send out
The damage of motivation.
By the various attachment structures on rearmounted NG electromotor passenger vehicle warm wind water pipe road carry out actual analysis, find to send out because of NG
Motivation passenger vehicle, when running summer, is easily generated a large amount of gas through heater exhaust gas liquid after heating, and now produce
A large amount of gases will circulate together with warm braw water in pipeline, forms the current of intermittent, and this kind is with the current of gas section
Because of circulation theory, eventually flow in engine radiator through the water inlet steel pipe of electromotor, cause the gas of engine interior
Resistance strengthens, and current now also can continue to increase at the resistance of engine interior；When coolant at engine interior because of gas
Generation and when cannot circulate smoothly, now will the most outwards overflow coolant by the expansion tank of electromotor, as
Now vehicle will show electromotor in running and the most easily lacks coolant, causes the operating temperature of electromotor not
Disconnected rising, strong influence electromotor safety in car load running.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of structure based on NG electromotor passenger vehicle warm braw pipeline, effectively
Solve rearmounted NG electromotor passenger vehicle to bear in the high problem of operating engine water temperature in summer, the heat radiation alleviating engine radiator
Load, makes engine operating efficiency higher, it is ensured that bus safety runs reliably.
It is an object of the invention to be achieved through the following technical solutions:
A kind of structure based on NG electromotor passenger vehicle warm braw pipeline, including frost removal, NG electromotor, water pump, heater exhaust gas, goes out
Water main line and backwater main line, be respectively arranged with multiple radiator on water outlet main pipe road and backwater main line, also include
First pipeline and the second pipeline；The water inlet of frost removal is provided with the first two-position three-way valve, at the water outlet of frost removal
Being provided with the second two-position three-way valve, the water outlet at water pump is provided with the 3rd two-position three-way valve, at the electromotor of NG electromotor
Tee T it is provided with at water return outlet；The engine water outlet of NG electromotor is connected to the water inlet of water pump by pipeline；Tail gas adds
The water inlet end of hot device and the first pipeline is respectively connecting to the 3rd two-position three-way valve, and the water inlet end on water outlet main pipe road is connected to tail gas and adds
The outlet pipe of hot device, the water side of water outlet main pipe road and the first pipeline is respectively connecting to the first two-position three-way valve；Backwater main line
Be respectively connecting to the second two-position three-way valve with the water inlet end of the second pipeline, the water side of backwater main line and the second pipeline respectively with
Tee T connects.
Preferably, the outlet pipe of heater exhaust gas is provided with the first non-return valve.
Preferably, described first pipeline and the second pipeline all use rubber tube.

Arm for backwater degasification is connected to expansion tank, and this expansion tank is provided with overflow pipe.Arm is set, can be by current
Gas cause expansion tank, reduce current vapour lock, it is ensured that the smoothness of current.
Compared with prior art, beneficial effects of the present invention is as follows:
The present invention by the warm braw pipe-line system of traditional rearmounted NG electromotor passenger vehicle is improved, add the first pipeline,
The water pipe in these two two independent loops of the second pipeline, with first, second and the 3rd two-position three-way valve jointly with the use of, shape
Become two set completely self-contained loops, i.e. winter modes with two different performance loop of pattern in summer.
Summer pattern: after current are flowed to water pump by NG electromotor, the control of the 3rd two-position three-way valve at pump outlet
Under, control current and flow at the first two-position three-way valve from the first pipeline, then in the control of the first two-position three-way valve downstream to defrosting
Device, current, after frost removal, flow back to the water return outlet of NG electromotor under the control of the second two-position three-way valve through the second pipeline,
Complete whole circulation.In this operating mode, current are only through frost removal, and not through heater exhaust gas, the most do not pass through
Radiator on water outlet main pipe road and backwater main line, i.e. this pattern mask the water lines of the radiator in car the most completely, by
Electromotor water out flows directly to frost removal after being extracted out by water pump, is being returned directly to electromotor after frost removal.The present invention closes
Reason utilizes the flow direction on NG electromotor passenger vehicle warm wind water pipe road, solves NG electromotor passenger vehicle when summer is run because of heater exhaust gas
The water temperature problem that reason causes, alleviates the heat radiation burden of engine radiator so that the temperature that electromotor worked in summer keeps
In the reasonable scope, it is ensured that the work efficiency of electromotor.
Winter modes: after current are flowed to water pump by NG electromotor, the control of the 3rd two-position three-way valve at pump outlet
Under, the direction controlling current can only arrive the water inlet of heater exhaust gas with guarantee current, and current heat through heater exhaust gas
After, after flowing through the radiator on water outlet main pipe road and water outlet main pipe road, then it flow to the frost removal of front part of vehicle, at second liang
Under the control of position three-way valve, current finally flow back to NG after the radiator on backwater main line and backwater main line and start
The water return outlet of machine, completes whole circulation.
Present configuration is simple, and the first pipeline and the second pipeline are rubber parts, low cost, only need to use monolithic pipe during installation
Folder support is bolted, easy for installation.
The present invention significantly reduces the probability that vehicle NG when summer is run develops engine trouble, and effectively reduces NG
The maintenance period of electromotor and cost.
The present invention arranges multiple non-return valve, can avoid backflow phenomenon, it is ensured that whole pipeline is properly functioning.
