Abstract

The utility model discloses an engine waste gas heat supply system with a bypass valve. The engine waste gas heat supply system with the bypass valve comprises a first waste gas exhaust pipe, a second waste gas exhaust pipe and a third waste gas exhaust pipe. One end of the first waste gas exhaust pipe is connected with an engine waste gas exhaust outlet and the other end of the first waste gas exhaust pipe is connected with an air inlet of the bypass valve one end of the second waste gas exhaust pipe. An air outlet of the bypass valve is connected with an air side inlet of a heating heat exchanger through a first waste gas bypass pipeline. The water side of the heating heat exchanger is connected with an engine cooling water pipeline. An air side outlet of the heating heat exchanger is connected with one end of a second waste gas bypass pipeline, the other end of the second waste gas bypass pipeline and the other end of the second waste gas exhaust pipe are both connected with one end of the third waste gas exhaust pipe, and the other end of the third waste gas exhaust pipe is connected with the external environment. According to the engine waste gas heat supply system with the bypass valve, heat is exchanged in the mode that engine cooling water is heated through engine waste gas, even though waste gas is leaked from the waste gas exhaust pipes of an engine, waste gas can not flow into a vehicle, and therefore safety of the heat supply system is improved.

Description

With the engine exhaust heating system of bypass valve

Technical field

The utility model relates to a kind of engine exhaust heating system with bypass valve.

Background technique

The heating system of most internal-combustion engines vehicle air-conditioning is to utilize the heat of automobile engine cooling water to carry out heat supply, and for car and truck, little owing to taking space, this method is feasible.But for motor bus, large owing to taking space, the heating load needing is large, and the heat of engine cooling water is limited, often can not meet the requirement of heat supply, a lot of motor buses have adopted heat pump heat supply mode for this reason, thereby have increased load and the oil consumption of motor.

When motor car engine work, there is the heat of half left and right to be taken away by waste gas, if utilize the heat of waste gas to carry out heat supply, can meet the heat request that supplies of motor bus.But original engine exhaust heater, by add tubing on engine exhaust pipe, utilizes waste gas to add hot air, more heated air is directly sent in car.If leaking appears in outlet pipe, the waste gas of discharging so will be together with heated air into the car, thereby the personnel in harm car are very dangerous.

Therefore, model utility goes out a kind of waste heat that can utilize engine exhaust, and the waste gas that can prevent again motor heating system is into the car highly significant.

Summary of the invention

Goal of the invention: the purpose of this utility model is to provide a kind of engine exhaust heating system with bypass valve, can utilize the heat heat supply of engine exhaust, thereby reaches fuel-efficient effect, can prevent again the waste gas of motor simultaneously into the car.

To achieve these goals, the utility model has adopted following technological scheme:

A kind of engine exhaust heating system with bypass valve, comprise engine exhaust gas exhaust piping, described engine exhaust gas exhaust piping comprises the first waste gas exhaust pipe, the second waste gas exhaust pipe and the 3rd waste gas exhaust pipe, one end of described the first waste gas exhaust pipe is connected with engine exhaust emission mouth, the other end of the first waste gas exhaust pipe is connected with one end of the second waste gas exhaust pipe with bypass valve suction port respectively, bypass valve air outlet is connected with the air side import of heating heat exchanger by the first exhaust gas bypass pipeline, the water side-entrance of heating heat exchanger is connected with cooling water pipe of engine road outlet pipe, the water side outlet of heating heat exchanger is connected with cooling water pipe of engine road intake pipe, the air side outlet of heating heat exchanger is connected with one end of the second exhaust gas bypass pipeline, the other end of the other end of the second exhaust gas bypass pipeline and the second waste gas exhaust pipe is all connected with one end of the 3rd waste gas exhaust pipe, the other end of the 3rd waste gas exhaust pipe is connected with the external world.

Beneficial effect: the utility model adopts the mode heat exchange of engine exhaust heated engine cooling water, even if leaking appears in engine exhaust gas exhaust piping, does not have waste gas yet and enters in vehicle, thereby improved heating system Security.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing, the utility model is done further and explained.

As shown in Figure 1, a kind of engine exhaust heating system with bypass valve of the present utility model comprises engine exhaust gas exhaust piping, described engine exhaust gas exhaust piping comprises the first waste gas exhaust pipe 1, the second waste gas exhaust pipe 2 and the 3rd waste gas exhaust pipe 3, one end of described the first waste gas exhaust pipe 1 is connected with engine exhaust emission mouth, the other end of the first waste gas exhaust pipe 1 is connected with one end of the second waste gas exhaust pipe 2 with bypass valve 4 suction ports respectively, bypass valve 4 air outlets are connected with the air side import of heating heat exchanger 6 by the first exhaust gas bypass pipeline 5, the water side-entrance of heating heat exchanger 6 is connected with cooling water pipe of engine road outlet pipe 8, the water side outlet of heating heat exchanger 6 is connected with cooling water pipe of engine road intake pipe 9, the air side outlet of heating heat exchanger 6 is connected with one end of the second exhaust gas bypass pipeline 7, the other end of the other end of the second exhaust gas bypass pipeline 7 and the second waste gas exhaust pipe 2 is all connected with one end of the 3rd waste gas exhaust pipe 3, the other end of the 3rd waste gas exhaust pipe 3 is connected with the external world.

In the time of needs heat supply, bypass valve 4 is opened, an engine exhaust part of being drawn by the first waste gas exhaust pipe 1 is directly discharged by the second waste gas exhaust pipe 2 and the 3rd waste gas exhaust pipe 3, another waste gas divides by bypass valve 4 and the first exhaust gas bypass pipeline 5 and enters heating heat exchanger 6, the engine cooling water that heating is sent into through cooling water pipe of engine road outlet pipe 8, then discharge through the second exhaust gas bypass pipeline 7 and the 3rd waste gas exhaust pipe 3, the heat exchanger that the engine cooling water being heated by waste gas is admitted in car by cooling water pipe of engine road intake pipe 9, thereby give Vehicle Heating.

In the time not needing heat supply, bypass valve 4 cuts out, and the waste gas of motor is discharged by the first waste gas exhaust pipe 1, the second waste gas exhaust pipe 2 and the 3rd waste gas exhaust pipe 3 completely, does not heat and changes the engine cooling water of holding 6 li of devices.

Due to the mode heat exchange of the utility model employing engine exhaust heated engine cooling water, even if leaking appears in engine exhaust gas exhaust piping, do not have waste gas yet and enter in vehicle.

The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
