Abstract
The utility model discloses a heating structure for a liquefied natural gas evaporator of a motor vehicle. The heating structure comprises a motor exhaust pipe and has the technical key points that a helix tube of the liquefied natural gas evaporator is arranged at the inner side of the motor exhaust pipe. The helix tube of the liquefied natural gas evaporator is arranged in the motor exhaust pipe, that is, the liquefied natural gas evaporator is connected to the middle section of the motor exhaust pipe as one part of the exhaust pipe so as to be used as one part of the exhaust pipe, and is connected onto the pipe wall of the motor exhaust pipe by external threads of the inlet and the outlet of the helix tube of the liquefied natural gas evaporator, therefore, the structure has simple form, is easy to realize and reduces the installing and fixing cost. The heating structure changes the form that the evaporator is heated by adopting motor cooling liquid or air conditioning medium in the traditional liquefied natural gas evaporator and adopts the motor exhaust heat to heat the evaporator, thereby not only meeting the functional requirements of the evaporator, but also improving the fuel availability of the whole vehicle, protecting environment and saving energy.
Description
Technical field
The utility model belongs to natural gas vaporization device mode of heating technical field on the Motor Vehicle, specifically a kind of heating arrangement that utilizes engine exhaust to Motor Vehicle natural gas vaporization device.
Background technique
Serious year by year along with the exhausted day by day and environmental pollution problem of the energy, countries in the world are more and more paid attention to the energy-conserving and environment-protective problem.Automobile industry has consumed a big chunk of world oil output, countries in the world are also more and more paid attention to the hybrid vehicle Study on Technology under this overall background, each big auto vendor drops into the exploitation that substantial contribution carries out various alternative fuel cars one after another, and the car that acts as a fuel with rock gas arises at the historic moment.LNG Liquefied natural gas (LNG) becomes the important development direction of type energy car owing to be convenient to storage and characteristics such as transportation, Security height, is subjected to paying close attention to widely and attention highly.
Summary of the invention
The purpose of this utility model provides a kind of heating arrangement that utilizes engine exhaust to Motor Vehicle natural gas vaporization device.Utilize engine coolant or air-conditioning medium to the form that vaporizer heats thereby change the conventional lng vaporizer, utilize the function of the heat realization vaporizer in the engine exhaust pipe.
The purpose of this utility model is achieved in that it includes engine exhaust pipe, is characterized in that: be distributed with natural gas vaporization device volute in the engine exhaust pipe inboard.
Natural gas vaporization device volute of the present utility model is arranged on middle one section of engine exhaust pipe inboard by position-limited rack.
Above-mentioned position-limited rack comprises: worm structure and spacing shim that vaporizer volute two ends are threaded with the engine exhaust tube wall.
The utility model the utlity model has following advantage with respect to conventional natural gas vaporization device:
1, simple in structure.The heat that conventional natural gas vaporization device utilizes is all from vehicle engine compartments, and the natural gas vaporization device generally is installed in the vehicle mid-rear portion, this circulation loop and pipeline that just must need a cover heat medium moves towards complicated, and problems such as fixing, sealing, protection have been produced, increase system and got complexity, caused cost to increase.The utility model only needs the natural gas vaporization device is connected on the engine exhaust pipe and gets final product, and having omitted a series of costs that the heat medium pipeline brought increases problems.
2, energy-conserving and environment-protective.Through the fuel combustion process of cylinder, the delivery temperature height of motor is finally discharged car body as tail gas, and this causes the waste of energy undoubtedly.The utility model utilizes the heat of engine exhaust to come the functional requirement of vaporizer has promptly been satisfied in the vaporizer heating just, has improved the fuel availability of car load again, has realized energy-conserving and environment-protective.
Description of drawings
Fig. 1 is a structural principle simplified schematic diagram of the present utility model;
The structural representation sketch that Fig. 2 vaporizer volute is fixed in outlet pipe
The symbol description of accompanying drawing major component
The 1-engine exhaust pipe; The import of 2-LNG Liquefied natural gas; 3-natural gas vaporization device volute;
The outlet of 4-LNG Liquefied natural gas.
To be described in further detail the utility model by example below; but following example only is the utility model example wherein; the rights protection scope of not representing the utility model and being limited, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
Example 1
Shown in Fig. 1～2,1 among the figure is the engine exhaust pipe of middle one section of Motor Vehicle, is distributed with natural gas vaporization device volute 3 in the inboard of this section engine exhaust pipe 1; Export 4 places in the LNG Liquefied natural gas import 2 of this natural gas vaporization device volute 3 and LNG Liquefied natural gas and have outside thread respectively, and be threaded on the tube wall of engine exhaust pipe, the wing plate 6 and the spacing shim 5 of the effect of being tightly connected also have been disposed with in the joint, make wing plate 6 be fitted in the outer surface of engine exhaust pipe fully, play fixation.
Natural gas vaporization device volute 3 is arranged in the engine exhaust pipe 1, is about to the natural gas vaporization device and is connected middle one section of engine exhaust pipe, as the some of outlet pipe.It changes the form that the conventional lng vaporizer utilizes engine coolant or air-conditioning medium that vaporizer is heated, but utilizes the function of the heat realization vaporizer in the engine exhaust pipe.This structural type simply is easy to realize, has reduced mounting cost, has improved the utilization ratio of car load fuel again, has reached effect in energy saving and environmental protection.The utility model adopts single spiral tube structure, can guarantee that exhaust fully heats vaporizer, can too not increase the engine exhaust resistance again, can not have influence on the power performance of car load.
Claims (3)
