Technical field
The utility model relates to a kind of vaporizer of LNG Liquefied natural gas, specifically is meant a kind of LNG Liquefied natural gas car load vaporizer.Belong to the motor car engine fuel supplying device.
Background technique
The cryogenic gas fuel (162 ℃) that is stored in the LNG Liquefied natural gas gas cylinder enters vaporizer by pipeline, and vaporizer utilizes the heat energy of engine coolant to come heated air fuel.When the LNG Liquefied natural gas car load when winter or northern area use, coolant temperature during engine start is lower, the heat that provides can not satisfy its gaseous fuel needed heat of vaporizing, cause the vaporization effect of gaseous fuel undesirable, cause the engine start difficulty, LNG Liquefied natural gas car load user is bigger to this complaint.
Summary of the invention
The purpose of this utility model is that to overcome existing vaporizer low-temperature vaporization effect relatively poor, and the defective and the deficiency of LNG Liquefied natural gas car load starting difficulty provide a kind of LNG Liquefied natural gas car load vaporizer.It is simple in structure, and the vaporization effect under the low temperature environment is better, can effectively improve the cold starting performance of LNG Liquefied natural gas car load.
For achieving the above object, the technical solution of the utility model is as follows: a kind of LNG Liquefied natural gas car load vaporizer, an airtight housing is arranged, housing is provided with intake interface, the interface of giving vent to anger, cooling liquid inlet and cooling liquid outlet, LNG Liquefied natural gas pipeline one end of enclosure interior is connected with intake interface, its the other end is connected with the interface of giving vent to anger, and the inside of described housing is provided with electrical heating element, two terminal of electrical heating element respectively be arranged on housing on two tenminal blocks be connected.
Electrical heating element described in the utility model is the water-proof type electric heating tube.
Electrical heating element described in the utility model is arranged on the spiral axis part of spirality LNG Liquefied natural gas pipeline.
Electrical heating element described in the utility model is coiled on the outer wall of LNG Liquefied natural gas pipeline.
Compared with prior art, the beneficial effects of the utility model are: 1, integrated electrical heating elements on the water-bath type vaporizer, the heat that can make full use of engine coolant comes heated air fuel, again can be under the low situation of ambient temperature, utilize electric heating element to heat vaporizer shell interior cooling liquid and LNG Liquefied natural gas, thereby improve the effect of its low-temperature vaporization, solved the starting problem of LNG Liquefied natural gas car load under low temperature environment well.2, simple in structure, compact in design does not increase the shared space of original vaporizer substantially, and it is convenient to change, and the LNG Liquefied natural gas car load that is particularly suitable for cold area uses.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of electric heating element 3 another kind of arrangements in the housing 1.
Among the figure: housing 1, LNG Liquefied natural gas pipeline 2, electrical heating element 3, intake interface 4, the interface 5 of giving vent to anger, cooling liquid inlet 6, cooling liquid outlet 7, tenminal block 8.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, a kind of LNG Liquefied natural gas car load vaporizer of the present utility model has an airtight housing 1, and housing 1 is provided with intake interface 4, the interface 5 of giving vent to anger, cooling liquid inlet 6 and cooling liquid outlet 7, LNG Liquefied natural gas pipeline 2 one ends of housing 1 inside are connected with intake interface 4, and its other end is connected with the interface 5 of giving vent to anger, the inside of described housing 1 is provided with electrical heating element 3, two terminal of electrical heating element 3 respectively be arranged on housing 1 on two tenminal blocks 8 be connected.Promptly be connected to the intake interface 4 that communicates with housing 1 inside, the interface 5 of giving vent to anger, cooling liquid inlet 6, cooling liquid outlet 7 and tenminal block 8 in housing 1 outside weld, be packaged with LNG Liquefied natural gas pipeline 2 and electrical heating element 3 in the housing 1, its complementary space in the housing 1 has been full of cooling liquid.Its cooling liquid is communicated with engine coolant circuit by cooling liquid inlet 6, cooling liquid outlet 7.Described electrical heating element 3 is the water-proof type electric heating tube, as the heating pipe in the electrothermal kettle.Also can adopt the PTC electrical heating element.
In Fig. 1, the LNG Liquefied natural gas pipeline 2 in the housing 1 is coiled into spiral-shaped, can increase the area of contact of LNG Liquefied natural gas pipeline 2 and engine coolant, thus the Liquefied Natural Gas fuel effectively in the heating pipe.At this moment described electrical heating element 3 can be arranged on the spiral axis part of spirality LNG Liquefied natural gas pipeline 2, promptly pass the spirality center of LNG Liquefied natural gas pipeline 2, make the heat energy of electrical heating element 3 can be liquefied morely natural gas line 2 absorb, to shorten the time of liquefied natural gas vaporization in the pipeline.
In Fig. 2, also described electrical heating element 3 can be wound directly around on the outer wall of LNG Liquefied natural gas pipeline 2.Directly LNG Liquefied natural gas pipeline 2 is heated, to improve its vaporization effect.
During the work of LNG Liquefied natural gas car load,-162 ℃ Liquefied Natural Gas fuel enters the utility model vaporizer from the LNG Liquefied natural gas gas cylinder by pipeline, cooling liquid inlet 6 on the vaporizer, cooling liquid outlet 7 is communicated with engine coolant liquor charging, liquid return pipe road respectively, and two tenminal blocks 8 on the vaporizer are connected with the motor power circuit respectively.If it is very low to enter the Liquefied Natural Gas fuel temperature of vaporizer, particularly at winter or north cold area, coolant temperature was also lower when motor had just started, the interior electrical heating element 3 energising work of vaporizer this moment, engine coolant and LNG Liquefied natural gas pipeline 2 in the heated shell 1 are normally vaporized to guarantee the Liquefied Natural Gas fuel in its pipeline.After motor moves a period of time, detect coolant temperature by temperature transducer and reach desired value, the expression engine coolant temperature is enough to satisfy the requirement of Liquefied Natural Gas fuel vaporization, its ECU (Electrical Control Unit) is with regard to the solenoid valve of control connection electrical heating element 3, disconnection is connected with the energising of electrical heating element 3, and at this moment vaporizer can rely on engine coolant to heat Liquefied Natural Gas fuel.
